WITNESSES
Dr. PATRICIA A. GRADY, DIRECTOR
DR. MARY LEVECK, ASSOCIATE DIRECTOR FOR SCIENTIFIC PROGRAMS
HERIBERTO RIVERA, BUDGET OFFICER
WILLIAM V. ROSANO, EXECUTIVE OFFICER
DR. RUTH L. KIRSCHSTEIN, ACTING DIRECTOR, NIH
DENNIS P. WILLIAMS, DEPUTY ASSISTANT SECRETARY, BUDGET, DHHS
Mr. Porter. The subcommittee will come to order. We
continue our hearings with the National Institute of Nursing
Research. We are pleased to welcome, again, Dr. Patricia Grady,
the Director. Dr. Grady, it is wonderful to see you. You always
do such a fine job before our subcommittee, as well as at the
Nursing Institute.
You are the institute that had the single largest
percentage increase of all last year. So you have special
responsibilities to tell us how you spent the money, or are
spending the money, I should say. So please, introduce the
people with you, and then proceed.
Opening Statement
Dr. Grady. Thank you, Mr. Porter.
Good afternoon, Mr. Chairman, and also members of the
committee. It is a pleasure to appear before you today.
I would like to thank the committee for its strong support
of NINR and nursing research. In this period of rapid
technological and demographic change, it is incumbent upon us
to ensure that nursing research grow to meet the present and
future health care needs of our nation's people.
Today I will discuss our achievements and goals for fiscal
year 2001 that relate to these concerns, especially in the
areas of chronic illness, end of life, and health disparities.
The President's budget provides a 3.3 percent increase or
$2,900,000 total AIDS and non-AIDS funding for NINR in fiscal
year 2001.
CHRONIC ILLNESS RESEARCH
With regard to chronic illness, NINR is committed to expand
this research to help patients manage their conditions.
Progress in this area is encouraging. In one recent
accomplishment, nurse researchers have further tested and
confirmed the value of a transitional care model using a
multidisciplinary team and advanced practice nurses. This model
involves comprehensive discharge planning for continuity of
care from the hospital to the home setting.
The results of this study, as shown on the chart before
you, clearly indicate that at six months following discharge
the intervention group, in this case older adults with common
medical and surgical problems, spent 65 percent fewer days in
the hospital and had 48 percent fewer re-hospitalizations, at a
total savings of 48 percent or nearly $600,000 to the health
care system.
Widespread use of this model could save significant health
care dollars and improve quality of care. This model is
currently being tested in patients with congestive heart
failure and also in a rural setting in Western Pennsylvania.
Most nursing research is clinical in nature and may be
carried out in settings that range from the hospital to the
community. Another recent finding concerns the use of feeding
tubes that are required to provide nutrition in many conditions
of acute or chronic illness. Incorrect placement of the tube
may deliver food to the respiratory system, which would have
serious consequences.
Currently, a stethoscope or x-rays are used to determine
tube placement. Nurse investigators have discovered that simple
rapid chemical test of aspirated feeding tube contents is a
more accurate alternative to the use of a stethoscope, and a
safer and less expensive one than x-rays. Clearly, it is also
more convenient for use in homes or long term care facilities.
This new method has identified the misplacement of tubes in
lungs with 100 percent accuracy.
END-OF-LIFE RESEARCH
Just as biomedical advances are changing the way we live
with illness, they are also changing the way we die. The
duration of both chronic illness and the dying process is now
prolonged. NINR is the lead institute for coordinating end-of-
life/palliative care research at NIH. Last year's request for
applications for research on end of life resulted in more than
100 responses, an impressive result for a relatively new area
of research.
Those studies that were funded will form a basis upon which
to build an important, growing effort. In fiscal year 2001, we
plan to expand our focus on end of life to better understand
and improve symptom management, decisionmaking, and also
communication between the family, the patient, and the health
team.
HEALTH DISPARITIES RESEARCH
With regard to health disparities, our efforts are directed
toward closing the gap. Historically, nursing research has
focused on minority issues. Currently, about 20 percent of our
budget is directed towards this area. In fiscal year 2001 we
will focus particularly on diabetes self-management and the
influence of ethnic and cultural differences on health.
An example of progress in our efforts to reduce health care
disparities is a study in which nurse researchers adapted an
arthritis self help questionnaire. Hispanics with arthritis
have had limited resources to help them manage their condition,
and sometimes restricted fluency in English may have excluded
them from certain health research projects.
The researchers have developed and tested a successful
Spanish language education program that includes how to better
communicate with the health care team members and manage
problems of mobility, pain, fatigue, and depression with their
arthritis. Throughout a one-year period of follow up, patients
experienced significant improvements in all of these areas.
Another version of this program is currently being tested
in Hispanic populations with other illnesses that are chronic,
such as diabetes, coronary artery disease, and chronic
obstructive pulmonary disorders. It has the potential to be
expanded throughout our country.
TRAINING AND CAREER DEVELOPMENT
Finally, we continue to emphasize training and career
development. Building nursing research capacity remains an
important challenge. In fiscal year 2001, NINR is reissuing its
institutional program request for pre- and postdoctoral
students with increased attention to two specific areas:
reducing health disparities and incorporating genetics into
nursing research.
This year we are also launching the Summer Genetics
Institute for extramural nurse researchers. A career
development program, now in its fourth year, offers mentored
research experiences for minority investigators. Examples of
studies being carried out by these investigators include
reduction of developmental problems of migrant infants,
prevention of suicide in rural Native American youth, and
improved screening for prostate cancer in African American men.
Conclusion
In conclusion, continued growth of nursing research is
vital to meet public demands and pressing national health
needs. Our contributions to the scientific foundation for the
work of health care practitioners, including the 2.5 million
nurses across the country, are already making a difference and
have further significant potential to do so.
There is still much to be done. The base of knowledge will
require considerable expansion in creative new directions as we
face the health challenges of the 21st century. And we at NINR
look forward to making a difference with research findings that
will help drive those changes.
Mr. Porter, we regret that you will not be here to hear the
results of these studies in person. We also know that you have
had a very important leadership role in making this research
possible and we are grateful.
Mr. Chairman, I am pleased to answer any questions that you
and the committee members may have at this time.
[The written statement of Dr. Grady follows:]
Mr. Porter. Thank you, Dr. Grady.
I am going to call on Ms. Lowey first, if she has
questions.
Ms. Lowey. Thank you, Mr. Chairman, and I do apologize, Dr.
Grady, that I have to run to another appointment, so I will
submit most of the questions for the record, and I thank you
for your important testimony.
PAIN RESEARCH
I just wanted to discuss one area very briefly, because you
talked about the end-of-life care and the treatment of pain.
There was an interesting story in a New York magazine recently
that examined the issue of pain management, and the article
discussed how patients' reports of pain are routinely
underplayed by providers, and that treating pain is not only a
problem at the end of life, it is not handled well for young
children with terminal illnesses.
I would be interested in an elaboration from you concerning
the treatment of pain. But one quick question before I run out
of the room.
I would be interested to know if the research has shown a
gender disparity on the reporting of pain.
Dr. Grady. It is interesting. We have funded several
studies that do show disparities on reporting of pain between
what the patient reports, what the relatives report that they
perceive the patient is experiencing, and also between what the
health team members report having observed these interactions
and observed the patients.
As far as gender reporting of pain, first of all we did
fund the study that you have heard about previously that showed
a difference in response to certain pain medications, that
women respond better to certain medications than men do. So
that there are gender differences that are biological, in terms
of responses. Whether it is the number of receptors or the
density is still being determined, but certain specific
chemicals work better with women and do not work with men.
Originally there was an interesting anecdotal report. The
study was thought to be a failure and the only persons who were
responsive to these particular chemicals were women. And then
the study was done in women and it was found that that, in
fact, was a gender difference. This was a remarkable finding
and precipitated a two-day workshop at NIH to look at other
biological changes.
But the studies also report differences in gender reporting
in the types of pain, that both genders subjected to the same
painful stimuli will report different levels of pain over
different levels of stimuli and different types. We are still
refining that, but evidently women mind certain kinds of pain
more than men and men object to other types of pain.
So there are some differences which are not clearly worked
out, but we are working on it.
Ms. Lowey. I have always been interested in the connections
between knowledge and pain. In other words, for those of us who
have given birth, if you know what is happening and you are
getting briefed, you can deal with pain very differently than
unexpected pain without any explanation.
Dr. Grady. Yes, that is a very good point. And just as an
aside, I am not sure if you were reading my mind. What I did
not say in the earlier study--that the one instance in which
the kappa-opioids, which were the substances effective in women
and not men, were reported to be effective--was in labor. So
one of my non-scientific staff said I wonder why labor was not
considered as painful as other things.
Ms. Lowey. It is just a delight.
Thank you very much, and I would like to follow up with you
on the research that you are doing in this area. I thank you
again for your testimony.
Thank you, Mr. Chairman.
Mr. Porter. Thank you, Ms. Lowey.
EDUCATION LEVEL OF RNS
As I explained, Dr. Grady, I have a meeting at 3:30, but I
want to try to pursue one line of questions before I turn the
chair over to Mr. Miller.
You said there are 2.5 million nurses; is that correct?
Dr. Grady. Yes.
Mr. Porter. Are those registered nurses, RNs?
Dr. Grady. Yes, those are registered nurses.
Mr. Porter. How many of the 2.5 million, if you know, and I
do not know if this is a question you would necessarily have
the answer to, but how many of those RNs have four year degrees
and what percentage have two year degrees?
Dr. Grady. The Division of Nursing compiles these
statistics, our partners in HRSA, but roughly about 50 percent
of those have baccalaureate degrees. As time goes on, the
percentage of baccalaureate is increasing over two-year
degrees. There are also some regional differences as well.
The statistics that we are learning about now, as the
enrollment in nursing schools has been going down, indicate
that we are seeing a resurgence in graduate education, higher
education. So that there is more of an attraction toward
baccalaureate and higher education.
Mr. Porter. I know this is properly a question for HRSA,
but we have already heard from them, so you are the target of
opportunity here.
Dr. Grady. I am perfectly happy to try and fill in the
blanks.
Mr. Porter. One of my educators came to me and said we
offer a two-year degree in nursing. They believe that, in many
instances, that is all that you need to be a competent nurse,
yet the nursing profession is pushing that everybody has to
have a four-year degree and they are basically going to put us
out of business. What would you tell them? What should I tell
them?
Dr. Grady. That is a difficult question and it is a very
controversial issue in the field. In this field, as in many
other fields, there is a drive toward advanced practice and
toward additional education. Typically when there is a nursing
shortage, it has come upon us rather suddenly because although
there is a cycle, for some reason it is difficult to predict
exactly when it is going to happen.
We are now predicting one for 2002, just so you can be
ready.
Mr. Porter. We are in one now, are we not?
Dr. Grady. We are just approaching one and we predict that
it will be fairly serious by 2002. So we are trying to do
something about it up front. We are meeting with our partners
in HRSA and the Department.
But the issue is a difficult one. Historically, when nurses
were in positions where they were assuming less responsibility
than they are expected to assume now, there was more of an
emphasis on a two-year degree. And now that they are expected
to assume more responsibility and they are more independent,
and in many settings where they are performing with a physician
colleague who is miles away or at the other end of a computer,
we are seeing more nurses with advanced certifications and
advanced clinical experiences, masters degrees, nurse
practitioners.
So I would say that it is a way to get started, but that
one would want to continue gaining new expertise and to keep on
moving.
Mr. Porter. Thank you, Dr. Grady. You are doing a fine job
there. It is wonderful to see you again. I am going to turn the
chair over to Mr. Miller.
Dr. Grady. Thank you, Mr. Porter.
HEALTH CARE OF THE FUTURE
Mr. Miller [presiding]. Dr. Grady, thank you. It is a
pleasure to be here. My mother was a nurse. She was one of the
old fashioned ones. She passed away two years ago at age 89,
but she finished the hospital-based nursing school, the real
old fashioned type.
Dr. Grady. So did I, Mr. Miller. And so did my mother. Yes,
about two years ago, I gave the graduation speech at that
school and closed down the school as it transitioned toward a
baccalaureate program. My mother and her twin sister, both
graduates of the same school, were there as well. So 60 years
later they were not practicing, but still active. So I can
identify with your mother.
Mr. Miller. When Mr. Porter was asking about the two-year
program, we have a community college that generates that. My
area is Bradenton, Florida, lots of elderly. I have lots of
senior citizens. Health care is our biggest industry. We do not
have much manufacturing, because of the hospitals, the nursing
homes, the home health agencies, and such, all have tremendous
demands.
One question, and unfortunately during this process, Dr.
Kirschstein, we have so many hearings going on at one time, it
is so frustrating, and I have had to miss so many. That is the
unfortunate part of these other challenges you have to try to
balance your time. So a couple of the questions may be a little
more general if you do not mind.
One of the things I like to talk about is what health care
is going to be like 20 or 25 years from now. I have been around
a lot because of my mother. Our family used to be in the long-
term care business, although we are no longer. And I was
chairman of a hospital for 10 years, in our community. So I
kind of have been around it. It was a volunteer job at a
community hospital.
I have seen it change dramatically, as you have. You talk
about the reason you need baccalaureate degrees is the
technology is amazing. Though I think, in many ways, the
technology has been slow going into patient care, compared to
what has happened in other areas of industry.
And then we have gone through all the NIH research. Dr.
Collins was here yesterday. We are just on the verge of such
changes. Newt Gingrich used to like to talk about that health
care 20 years from now would be a replacement business. That is
real futuristic, but you have seen it change. How do you see it
20 or 25 years from today?
SELF-MANAGEMENT OF CHRONIC ILLNESS
Dr. Grady. We have been seeing a number of changes. The
technology will impact on us because of making certain things
easier and making many things possible. One of the things that
we are noticing and we are expecting and preparing for, and you
can see in the studies that we are funding in our areas of
emphasis, is that as we are living longer and living better we
hope, that people will be living longer and will be
experiencing chronic illnesses, but in general will be learning
to better manage those themselves.
So we are focusing a great deal of our efforts on helping
patients in self-management of their disorders, whether it is
diabetes, whether it is arthritis. These will be chronic
illnesses that one will be able to manage and keep on with
activities of daily living and living a fulfilling and rich
life.
So we are directing a lot of our focus on that area,
through the use of prevention, exercise programs, dietary
modification, trying to get, for example, the elderly to remain
active and to remain in the community. To test out programs as
to whether or not, for example in South Florida on the other
coast, we are testing out a program of exercise in older
individuals, whether or not the resistive exercise program
versus the walking program versus just ordinary lifestyle that
they would live. Which of these is most beneficial and why? We
are looking at outcomes such as increased aerobic capacity,
decreases in body weight, and so on.
One of the risk factors for falls in the elderly, in
addition to the bone density issues, a study that we have done
that has identified that the problem of balance is one of the
more difficult ones in the elderly is related to weight. It is
not perhaps a surprise, but people who are thinner have a much
better balance. People who have extra pounds, even a small
percentage of body fat, tend to have balance problems and tend
to be more vulnerable for falls.
So we are doing a number of studies in this area.
Mr. Miller. It is not out of the question, 10, 20, 15 years
from now, that cancer, Alzheimer's, some of these things that
are the dread diseases of today, I know you do not want to say
that is going to be the case, but it is not far-fetched to say
that. We are making progress all the time.
I was fortunate with my mother, my mother-in-law just
recently, and my father, they were all up in their late 80s,
early 90s. So old age eventually got them.
PREVENTION OF ILLNESS
Dr. Grady. We are rapidly approaching what we call the
post-genomic era. The genome will be identified and we will be
in a time when genes for certain disorders, or as Mr. Porter
and Dr. Olden were talking about earlier, a propensity for a
disease will be identified. Then only about 5 percent of genes
will be one gene/one disease. But the others will identify the
risk factors or people who are at risk.
So then it will be up to those of us in the health
community, particularly the nursing community, to identify and
to help modify the other risk factors. For example, in the case
of lung cancer or even a respiratory disorder, that the other
factors of the environment, factors of smoking, factors of
occupational choices will be risk factors that would be
identified for increasing your propensity to develop that
disease since you already have the gene, or would decrease your
propensity.
So we are already starting to look at some of those areas.
TELEHEALTH TECHNOLOGY
Mr. Miller. I made a comment in my opening statement about
technology. I have not been as close to it in recent years, but
technology really has not come to the bedside as quickly in
health care as you would have expected it. It is in the
laboratory. It is there.
Now the bedside is the nursing area. Maybe we are getting
ready to see a rapid movement in that direction. What is
happening in that area?
Dr. Grady. Let me, if I might, take that question and
approach it from a slightly different tack. We have a small but
growing program in telehealth. We are using technology, putting
it to work in a somewhat different way. So that we have
programs directed in several areas.
We have several studies using telephone monitoring and
telephone touching bases with patients to determine how they
are following a particular program of prescription of
activities or how they are doing. We are also using that
technology for screening programs and monitoring.
A second way that we are testing technology is that of home
monitoring for patients who have certain chronic illnesses. One
population of patients that we are following is a patient
population who are post-transplant, lung transplant. Using a
home monitoring system, including spirometry, electronic diary,
et cetera, those patients are being monitored. The chance of
infection or rejection is very high during the first year. So
in the patients who are being tested, there is a high rate of
compliance and we have been able to detect some early changes
using this technology and report that and attend to them.
Another way that we are using technology is in children
with asthma. As all of those of you in the room who are parents
know, children do a great deal of learning at a very early age
through the use of computers, much more than we did as
youngsters, and even some of us as adults. But there is a
computer program that was designed for adults with asthma that
is being adapted for children and tested by nurse researchers,
in fact, at Johns Hopkins University.
This computer program, working with the children, helps the
children to identify allergens in the home and how to modify
their behavior to decrease the number of asthma attacks. For
example, bedroom allergens and things of that sort. It is being
tested out, and the early preliminary studies do show a
decrease in the number of asthma attacks in those children. We
cannot say what the final outcome will be, but it is very
promising so far.
MEDICAL ERRORS
Mr. Miller. There has been publicity about the medical
errors within hospitals, and I do not know if this fits into
NIH research but it--you know, it can fit into nursing research
and it fits into the whole technology area. I mean, what
about----
Dr. Grady. We are actually funding three studies in this
area that are looking at the relationship between nurse
staffing and adverse outcomes, including medication errors.
They are also looking, in addition to medication errors, at
complications such as pneumonia, urinary infection, falls, and
so on. These studies are being carried out--one is a multi-
site, multinational study which is being carried out in the
United States, Canada, Scotland, and the United Kingdom--
specifically England. Another is being carried out in the
Midwest, a multi-site study. And a third one is being carried
out in 11 southeast States and D.C., including North Carolina,
South Carolina, Virginia, West Virginia, et cetera.
Those studies are four- to five-year studies and two of
them are about halfway through, and a third one has just begun
this last year.
Mr. Miller. You are talking about technology, one thing
that our economy that--you know, economics background is always
intriguing. We do not have inflation in this economy and we
have such low unemployment. I mean, that is basic economics 101
does not explain that one away, except for the productivity
increases in, especially because of technology. Are we seeing
those in health care?
Dr. Grady. We are in fact seeing----
Mr. Miller. The productivity. I mean, you are able to
deliver more for less?
Dr. Grady. To some extent, yes. It is difficult to answer
that with a straight yes or no because in some areas we are
seeing major differences. In other areas where patients are
very critically ill, even with the advent and the assistance of
technology, those are still very labor intensive areas. So the
answer is mostly yes, but it is somewhat situation and patient
dependent.
NIH DEVELOPMENT OF TECHNOLOGY
Mr. Miller. Does NIH do any of this technology--I mean,
technology is everything in health care. Because it may not
always be that basic. But I mean, it is kind of like I
mentioned earlier I was visiting the Brain Institute at the
University of Florida and as an institute it brings--the
engineering school is there, and there is engineering
professors involved in the meeting and things. So the
opportunities become--you know, with the magnetic imaging
capacities they were developing there was just so impressive.
But one of the strengths is it is not strictly a medical
school. It is an institute separate.
MEDICAL IMAGING
Dr. Kirschstein. It has become a medical field, Mr. Miller.
The NIH has for many years been involved in particular areas of
technology development. A great deal of technology development
is being performed in the National Heart, Lung, and Blood
Institute such as activities related to pumping; all the
technology that is involved in bypassing the heart during
coronary bypass surgery, for example. And there is more and
more of that.
All the imaging technology that you have been seeing over
the last few days has led to the fact that in fact we have
begun to work very closely with engineers, physicists and
mathematicians. We have had a committee, a coordinating
committee among the institutes called BECON, Bioengineering
Consortium, which will be and already is just about set to
become an office of bioengineering and bio-imaging within the
office of the director, to coordinate all these technologies.
We have had two and will have a third this June, large symposia
on the subject.
The other thing about technology in hospitals, intensive
care units, and particularly intensive care units for premature
infants, are highly dependent on the most sophisticated
technologies, most of which are handled by highly skilled,
hardworking, on the job I do not know how many hours a day,
nurses it is just a remarkable activity, which is all the more
reason I believe that the nurses with the advanced degrees and
bachelor's degrees are required, because the technology is
very, very sensitive and one small error would really be
catastrophic.
Mr. Miller. Maybe I am wrong about this technology. Maybe I
am thinking about the patient in the hospital that is still
charting by hand a lot. I mean, in the specialized areas like
in the intensive care--of course, most people it seemed like in
a hospital are always intensive care anyway. I remember being
told that back in the early 1980s, if you do not belong in
intensive care, you do not belong in the hospital just about.
And it has changed. I mean, our hospital in Bradenton was a
500-bed hospital that I was involved in and you do not--well,
you know the changes.
Dr. Kirschstein. Yes, absolutely.
Dr. Grady. Across the country.
Mr. Miller. It is just a very different institution from
what it was.
I am glad to hear you are working on this end-of-life
studies. Are you the only----
END-OF-LIFE RESEARCH
Dr. Grady. No, actually this is trans-NIH. We are a lead
institute for coordinating, but when we sent out the RFA last
year, the request for applications, there were eight other
institutes at NIH and the then-Agency for Healthcare Policy and
Research that has been renamed Agency for Healthcare Research
and Quality. So that we actually plan to move forward, it is
one of our areas to emphasize in the coming year in 2001. There
is a great deal we do not know, so we are collaborating with
several others.
Mr. Miller. I should not take so much time, but I do not--
--
Dr. Grady. No, that is okay.
Mr. Miller. If you do not mind. I hate to keep everybody
here because we could just sit and talk----
Dr. Grady. We can stay. My time is yours, sir.
Mr. Miller. Well, I do not mean to--it is not fair to take
advantage of the fact that I am sitting up here.
Dr. Grady. We do not feel at all taken advantage of.
REGIONAL DIFFERENCES IN HEALTH CARE
Mr. Miller. Okay. Now I forgot what I was going to ask.
Regional differences. This is years ago, I remember in long
term care is that in Florida, for example, the rate of
institutionalization was significantly lower than the State of
Minnesota. My impression was--correct me if I am wrong. This is
30-year-old data.
But in areas where we have these large retirement--we have
mobile home parks that have thousands of people in one mobile
home park. And they live right next--that is how my
grandparents moved to my area of Florida. They were trailer
parks back then, and they are actually called manufactured
housing. But they are trailer parks. And they are very close
together but they all take care of each other.
I mean, to grow old in Florida is, I find, a lot easier
than growing old--as my in-laws grew old in Baton Rouge,
Louisiana. The doctors and nurses--I mean, if you not into
geriatrics, you do not--you should not be practicing medicine
in my area. So there is that regional difference.
Dr. Grady. We would agree with you. When you look at the
titles of the research that we fund, and when you look at the
States that we fund it in, you can see a number of regional
differences reflected in the types of research studies that we
fund because of that.
But we are, because of the growing age of the population,
the mean age of the population, and consequently, the increase
in chronic illness with that population, we are funding many
more studies dealing with the elderly, and dealing with trying
to help people with what we call symptom management. How do you
carry on quality of life and how to you maintain your lifestyle
despite these annoying chronic illnesses?
COMPETING AND NONCOMPETING GRANTS
Mr. Miller. Let me do something, if I may. I want to kind
of go through--I have been looking at these all day and I just
want to ask a question. I am going to use as an illustration as
I walk through what is on my page 14 or 15. I do not know who--
when we talk about the non-competing research--I mean, this is
the same format for all the institutes so I am just, you know.
How do you define non-competing? Because these are not the
renewal. Or are these renewals?
Dr. Grady. Actually they are in a sense, but when we make a
grant, each year when we have an appropriation approximately
three-quarters of that, up to 75 percent roughly--since the
average length of grant is four years, we make a grant award to
someone and it is for this year, but it is also for what we
call outyears. So it would be for three more years. And those
are the so-called non-competing renewals, because the idea is
that the person, the trust is that they will do good work and
they will report progress each year, so that there will be a
continuation of their funding. But it is a non-competing
continuation.
Then at the end of that period of time, at a four-year
renewal, the application will be renewed competitively. It
comes in again with new goals and shows the progress that they
have made over the total of the award. Then if it competes
successfully it is called a competing renewal and an award is
made to that individual for that year and X number of outyears.
Mr. Miller. How often do you have to suspend or they do not
complete their requirements? I would ask you that, and also for
the other institutes too.
Dr. Grady. That does vary across NIH and Dr. Kirschstein
may want to comment. Our institute is a young institute, as you
know, as we actually--we had a very large increase last year.
It was our best year ever. So we had, prior to that, in 1999 we
had funded about 14 percent of all the research that came in.
We were able to fund 14 percent. So all the rest of
appplications went back to be revised or whatever.
Last year with this really very large budget we hope, we
expect in the year 2000 to be able to fund up to 24 percent of
all the studies that come to us. But those will be the
competitive applications.
Now because we are also new and young, we do not have as
many of the competing applications where people write a grant,
get a grant for four or five years, and then compete. Last year
we funded four competing renewals. So we had four investigators
who had completed the research, wrote a renewal, and came in
and got more funding.
Mr. Miller. How about not completing the four years because
they are, you know----
Dr. Grady. That is unusual in our institute. I believe it
is unusual across the NIH, but I would defer to Dr.
Kirschstein.
Dr. Kirschstein. Mr. Miller, first of all when we make an
award and it has been peer reviewed and the reviewers have said
that the outline of the work that the individual proposes to do
is very meritorious and needs four years to have real progress,
we make the award for one year but we have a commitment to make
continuing awards for the next three years. That is the non-
competing fraction of our budget: the commitment to those
grants.
Mr. Miller. Do those with individuals--it is a combination
of individuals and institutions. When that individual, the lead
researcher moves, which has to happen----
Dr. Kirschstein. There are two possibilities. First of all,
all awards are made to the institution in the name of the
investigator who has described his or her work, and the
institution has signed off that this investigator is on the
faculty of that institution and will do the work. If an
investigator moves, and will be active in research at another
institution, there is basically a gentleman's agreement between
the two institutions that the work will be transferred to the
new institution.
There are rare occasions where that is not true. For
example, an investigator dies or an investigator leaves
academia and goes to industry. That investigator often has left
behind other individuals who are doing the work in the
institution that he or she was in. And if the institution can
justify to Dr. Grady's institute or one of the others that
there is another investigator who is equally qualified to carry
that work forward, then that can be left in that institute.
AVERAGE SIZE OF GRANTS
Mr. Miller. What is the average size in your institute and
overall for the entire NIH?
Dr. Grady. The average size in our institute is
approximately $265,000 for RPG, research project grant.
Mr. Miller. Per year? Or per four years?
Dr. Grady. Yes, per year.
Dr. Kirschstein. That includes indirect costs.
Dr. Grady. Includes indirect costs. That is total cost.
COMPETING RENEWAL GRANTS
Dr. Kirschstein. At the end of the four-year period, as Dr.
Grady described, the investigator has developed a certain body
of knowledge so that he or she is in a position to now move
this forward and to ask a whole new series of questions related
to what was done originally, and puts in what we call a
competing renewal. It goes through the review process again.
Now having proved himself or herself the first time, you would
anticipate that they would be even more successful than the
first time an investigator comes in.
Indeed, when we talk about success rates and we say that
the overall success rate will be 26 percent for all of NIH
which is what we are projecting in fiscal year 2001, it is
about twice as high for competing renewals than it is for new
applications. The new would be, in this projection, 21 percent;
competing renewals, 45 percent, for an averaging out, because
there is a difference in numbers, of about 26 percent.
Now that does not mean that the person who is coming in for
a competing renewal gets a free ride. If, for one reason or
another, the review group feels that either the promise of what
he or she did during the first four years was not sufficient,
or he or she has proposed something that really is not
meritorious, they can be told they cannot have a competing
renewal.
So it is a process that has some self-renewal in it, but we
are also very, very cognizant of the need to bring newly minted
investigators into the field. And we work very hard and we made
a promise, as you all were very generous with our budgets, that
we would support year by year the same number or even more
newly minted investigators because the lifeblood of our
research is the new idea.
Mr. Miller. What is the average size overall for NIH,
about?
Dr. Kirschstein. It is a little larger than what Dr. Grady
funds in NINR--it is about $320,000 to $330,000. So it is a
little larger. This is a small institute and the nursing grants
do come in somewhat smaller than the average.
ADMINISTRATIVE SUPPLEMENTS
Mr. Miller. What is administrative supplements?
Dr. Grady. Administrative supplement is--there are two
kinds. But the most common one that we use is when someone
applies for a grant and they have this award, as Dr.
Kirschstein said, it usually is about four years. During that
time they may find a very interesting finding that would be
small and they would like to have additional funds for. So they
write a smaller grant and ask to compete for more funding, and
that is added onto their award.
Dr. Kirschstein. There is another type of administrative
supplement as well. As we have been talking about this week,
the pipeline for minority investigators, new young graduate
students, new high school students who we want to inspire to do
research is woefully small. We do provide what we call
administrative supplements so that a professor can train some
of these people. We provide money for that training as an
administrative supplement.
RESEARCH CENTERS
Mr. Miller. What are research centers?
Dr. Grady. Research centers are typically aggregates of
investigators who are gathered around a central theme. Now
there are several types of centers. But typically they are the
large centers where you have larger projects around a theme
such as studying various aspects of stroke for a stroke center,
or diabetes for a diabetes center, et cetera. That is a fairly
large center typically. It is called a P-50 on your chart.
Other centers that are smaller are the kinds of centers
that we particularly use in our institute. One of these is what
is called a P-30 on your chart. What that is, it is a core
center, and it is intended to bring investigators together to--
--
Mr. Miller. Specifically for nursing or is it----
Dr. Grady. In our institute it is specifically for nursing.
But ours are multidisciplinary. So we encourage nurses and
others to work together in a multidisciplinary way and to
provide, to share resources so that they can attract other
investigators and get R01 funding. So it really is to form the
infrastructure.
There is yet another kind that we have used that our
council has been discussing; that is what is called a
developmental center. It is an even smaller amount of money for
about three years and it is to get groups that are close to
being competitive, to try to help them to be more competitive.
And to do preliminary studies to show that they have a
hypothesis that looks like it is worth testing, and to come in
for a larger amount of funding.
Mr. Miller. You have 10 research centers?
Dr. Grady. Yes, we have 10, and those are the core centers.
Those are all, they are basically about $300,000 apiece, and
they are--actually one of these is in conjunction with the
Aging Institute network of centers, research centers for aging
minority individuals. So we are funding one of those. We also
participate in the study of women across the Nation, which is
with the Office of Women's Health and other institutes.
Then the remaining ones are the core centers which are
newly let out last year and seven of those have specific
emphasis on health disparities. So that we are trying to build
up the research in that area.
GEOGRAPHIC DISTRIBUTION OF GRANTS
Mr. Miller. At the hearing that I had to leave the first
day and Mr. Wicker was bringing up the situation and you
discussed the geographic issue. I was a little surprised almost
by it in a way, and how Mississippi--you know, his home State
does not really get very much through NIH. I do not think you
should target necessarily just for geography. That is not the
way we want this to be done. But you also have a reason not to
let it all concentrate in Boston, and Chicago, Los Angeles. How
does that play into overall----
Dr. Kirschstein. As Dr. Grady was answering your question
about developmental centers I was thinking about that. Actually
when I realized that the State of Mississippi was not receiving
very much in the way of research grants I was surprised. You
are from Baton Rouge, Louisiana. I went to Tulane Medical
School in the late 1940s and early 1950s, before the University
of Mississippi had a medical school. When they founded the
medical school, which was about 1953, 1954, they took some of
the very best faculty, many of whom I knew, from Tulane and
they all went up to Mississippi. And by the time I went back
there to visit this year or in the fall, many of them were no
longer in practice.
It was a very active medical school. I am not sure what
happened in that period of time, but we are working actively
with them again to try to develop research, and these
developmental centers might be a way to do it.
What was interesting to me was that the pharmacy school,
which is on the main campus at Oxford, had a much more active
research program than did the medical school. Now whether or
not this was because Mississippi needed to do something about
its health care system--in fact the medical students at Tulane
who were from Mississippi when I went to medical school, were
having their tuition and living costs paid by the State of
Mississippi. And the State of Florida did the same thing at the
time before the University of Miami and the University of
Florida had medical schools.
Mr. Miller. Yes, Florida just got a medical school at the
University of Florida in 1958 or 1956.
Dr. Kirschstein. Yes, and Miami was just a little bit
before as I recall. So it may----
Mr. Miller. This is not just Mississippi. I assume there
are other States that have the same concern.
Dr. Kirschstein. Yes, but we visited Mississippi. We have
been working with them. We are planning to do the same thing in
Oklahoma. We told Mr. Istook we would go to Oklahoma in the
spring and we expect to be able to help these schools and these
States to develop programs.
Mr. Miller. Does that come into consideration in anything
you are doing? I am not here to advocate for Mississippi. I
mean, I want to take care of Florida. But I----
AREA PROGRAM
Dr. Grady. Actually it is very interesting. We have a
somewhat different situation in the schools of nursing--there
is a very wonderful program at NIH that is the AREA program,
Academic Research Enhancement Award. That is given to schools
who receive limited NIH funding. And as it turns out, with
schools of nursing across the country, there are only five
schools that are ineligible for this program. So most of our
schools across the country are eligible for these small funds.
They are roughly $50,000 a year for two years. They are
renewable.
So we do fund in a number of States where there are very
good schools of nursing and they are just beginning to be more
research intensive.
We are actually working with Mississippi because the
Jackson heart study has started there. The school of nursing
there is very active and very research oriented. They are
actually coming up next month. We have met with them before,
but we had an RFA that we let out, just in January actually,
for attaching to clinical trials small supplements. We would
give supplements to nurse researchers to be able to work with
ongoing clinical trials, to ask specific questions related to
symptom management or other issues that would complement the
trial but might not be the central focus.
The Jackson heart study group is very interested in it and
we have been working with the Heart Institute and the group
from Mississippi and hope that--they tell us that they will be
responsive to that. We think it would be a good opportunity.
We even have funded studies in Oklahoma.
Mr. Miller. I have taken a lot more time than--so I really
appreciate the opportunity to ask some clarifying questions.
Dr. Kirschstein. We enjoyed it.
Mr. Miller. Thank you very much. And thank you for being
here.
Dr. Grady. Thank you, Mr. Chairman.
Mr. Miller. The meeting is adjourned.

NATIONAL HEART, LUNG, AND BLOOD INSTITUTE
WITNESSES
DR. CLAUDE LENFANT, M.D., DIRECTOR
DR. CARL ROTH, PH.D., ASSOCIATE DIRECTOR FOR SCIENTIFIC PROGRAM
OPERATION
DONALD P. CHRISTOFERSON, ASSOCIATE DIRECTOR FOR ADMINISTRATIVE
MANAGEMENT
JOHN TIBBS, FINANCIAL MANAGEMENT OFFICER
DR. RUTH L. KIRSCHSTEIN, ACTING DIRECTOR, NATIONAL INSTITUTES OF HEALTH
DENNIS P. WILLIAMS, DEPUTY ASSISTANT SECRETARY, BUDGET, DEPARTMENT OF
HEALTH AND HUMAN SERVICES
Opening Remarks
Mr. Porter. The subcommittee will come to order. We
continue our hearings on the appropriations for NIH with the
National Heart, Lung, and Blood Institute. We are very pleased
to welcome once again one of our favorite Directors, Dr. Claude
Lenfant.
If you will introduce the people with you, and then proceed
with your statement, Dr. Lenfant, we will then go to questions.
Dr. Lenfant. Thank you, Mr. Chairman.
On my far left is Mr. Don Christoferson, the Associate
Director for Administrative Management. Next to him is John
Tibbs, who is the Budget Officer; and Dr. Carl Roth, who is the
Associate Director for Scientific Program. And, of course, you
have met Dr. Kirschstein and Mr. Williams.
Let me begin my remarks, Mr. Chairman, by saying that we
are having a wonderful year, which gave us the opportunity to
do much for the scientists that we serve and, most importantly,
for the patients who, in turn, are served by the outcome of the
science we support.
In the next few moments, I would like to highlight some of
the investments that we are making at the present time.
[The information follows:]
Dr. Lenfant. As you can see on this first chart, for the
sake of simplicity I have grouped our investments into four
categories, but I should tell you that each that you see here--
genomic/genetic medicine, clinical research, bioengineering,
and other--each of them comprises a number of initiatives which
I could describe if needed.
The thing that I would like to underscore is that each
initiative that we have is directed toward at least one goal of
our programs; the first goal is to make maximum use of all the
research opportunities and new technologies that are available
today; and the second goal is to to ensure that the health
practices reflect the best knowledge that we have today.
Meanwhile, I would like to show you some specific examples
of how research that began at the very basic levels contributes
to better care of the patients.
[The information follows:]
CONGESTIVE HEART FAILURE
Dr. Lenfant. On the next chart you can see some data
concerning congestive heart failure.
As I trust you remember, Mr. Chairman, of all the areas I
have discussed with this committee, the importance of heart
failure, the prevalence of which today is increasing in
epidemic proportions, is a condition which is very difficult to
treat because of the unpredictability of its course. However,
things are changing.
What you can see here on this chart are two curves which
show the course of congestive heart failure in two patients who
initially had the same symptoms, the same characteristics, but
what distinguished them is a different genotype, which is
indicated here as ``variant A'' or ``variant B.'' These are two
different mutations of the same gene that these patients have.
The important thing is that, as you can see, the patient
with variant B has a course and an evolution of his disease
which is much faster than that of Patient A. And the value of
that knowledge is that it gives us the opportunity to predict
the course of the disease by knowing the genotype of these
patients, and therefore it helps us to develop the appropriate
strategies, which are very important for these patients.
For example, in the case of Patient B, Variant B, you could
predict that this patient would be in need of a heart
transplantation much sooner than a patient with variant A, and,
therefore, you could prepare for that and the therapeutic
strategies.
[The information follows:]
ASTHMA
Dr. Lenfant. The next case that I want to show you has to
do with asthma. Asthma, as you know, is a very prevalent
disease which affects lots of people in this country,
especially youngsters, and most of them are treated with
bronchodilator therapy. The problem is that a great number of
patients do not respond well to this therapy.
Here, again, what genetics teaches us is that we can
predict--as you can see here by looking at different variants
again of the same gene in these patients--who is going to
respond to the therapy.
Of course, the value of that is very important, because you
can therefore select the therapy which you know is going to
work, rather than spending lots of time and sometimes money
administering to these patients therapies which eventually may
not work.
[The information follows:]
MAGNETIC RESONANCE IMAGING
Dr. Lenfant. The third example that I want to show you is
the application of engineering imaging in clinical medicine. I
am referring to magnetic resonance imaging.
What you can see on this chart here is the evolution of
this technology during the last ten years.
In 1990, it would take five minutes to get the picture that
you see here. In 1995, we were able to reduce the time to 20
seconds to get that picture. This year, we can do it in real
time. What we can do with that, I am going to show you on the
wall here with a video.
Here is what you see, putting a patient in an MRI. In real
time, the heart of this patient, you can see the contractions,
the ejection of the blood into the aorta that you see here.
Now, what you can do is take a cross section in this
direction or that direction, whichever direction you want, and
that would allow you to detect immediately any lesion in the
heart of this person.
Now, that is a normal heart. It could be yours, mine, one
of any person in this room, I hope.
[The information follows:]
Dr. Lenfant. Now, I am going to show you, in the last chart
that you see here, the importance of that.
In this country, each year there are millions of patients
who enter an emergency room with chest pain, and the question
is: do they have heart attack or not? And if they have it, it
has to be treated very quickly.
The first thing that is being done when these patients
enter the emergency room is to give them an EKG. Unfortunately,
the electrocardiogram is going to give you definitive answer in
only approximately 20 percent of the cases.
Now, for these cases it is very good. You can treat them
immediately, and within 15 minutes they would have their
therapy, which is a life-saving therapy.
Unfortunately, for 80 percent of them, the EKG is
indeterminate. So in the past, the option that we had was to do
some enzyme measurements, and these enzyme measurements may
take from one to nine hours, during which time the damage to
the heart may increase and basically leap to a much more
serious heart attack or complication than would be otherwise.
With the MRI, the magnetic resonance imaging that I showed
you on the wall, within 35 minutes you can have a precise
diagnosis and say yes, this patient is in the process of having
a heart attack, or not.
The advantage of that is very clear--better result for the
patient, less expensive. If the patient does not have a heart
attack, you do not need to keep the patient in the hospital. If
the patient has a heart attack and it has been diagnosed
quickly, therefore treated quickly, the patient will stay less
time in the hospital.
Finally, because the treatment has been given very early,
the risk of this patient eventually evolving toward heart
failure is much less than it would be otherwise.
It is a considerable saving of time and money for the
patient and for the society, as well.
So these, Mr. Chairman, are a few examples that I wanted to
show you of what we are doing today, and I will be pleased to
answer any questions that you may have.
Mr. Porter. Thank you, Dr. Lenfant.
[The written statement of Dr. Lenfant follows:]
HEART FAILURE
Mr. Porter. I have a question about what you just said.
If you go into the hospital with chest pains and perhaps
other symptoms of a heart attack, don't they treat you as if
you are having a heart attack in any case, even before
diagnosis, just as a precaution?
Dr. Lenfant. No, you would not do that because this
treatment, which is basically, by and large, blood clot
dissolving therapies--most of these heart attacks are due to a
blood clot--there may be some side effects and complications to
which you would not want to expose a patient unless it is
necessary. You need to have a definitive diagnosis before you
do that.
Mr. Porter. You would not even provide, say, aspirin or
nitroglycerin or anything until you have done one of these
procedures?
Dr. Lenfant. Well, that may be done, but nitroglycerin is
also a medication which is not free of side effects, and
aspirin, it would take some time for it to get to do what it is
supposed to do.
Basically, any patient will not go into intensive treatment
unless there is a firm diagnosis of the condition, and that is
why, in most instances, the physicians in charge will want to
have the results of an enzyme test, and that, depending on the
magnitude of the damage to the heart, if there is lots of
damage, the result of the enzyme measurement may be very quick,
but if it is moderate damage it may take a long time. Of
course, during that period of time the damage is increasing.
So the prospect of the MRI diagnosis is a tremendous step
forward in the practice of this emergency medicine.
Mr. Porter. If you can do the MRI in real time, as you
showed us, why does it take 35 minutes to get a diagnosis?
Dr. Lenfant. Because you have to make some slices of the--
what I showed you is the view, if you want, but you have to do
some slices and basically cut the heart, if you want, with the
computer, in a number of slices so that you can determine,
number one, where the lesion is and, number two, the magnitude,
the importance of the lesion.
Now, the reason you want to know where the lesion is,
because you want to know which artery is obstructed so that you
can go and open it up, if necessary, with angioplasty.
Mr. Porter. Is there potential that these slices in the
future, as technology evolves, can be made much more quickly so
that you are not having to wait, because you have obviously had
a great progression from 1990 to the present.
Dr. Lenfant. We are confident that, indeed, this time will
be reduced in time.
The progression of that, as you can see, has been quite
logarithmic. Ten years ago it was five minutes, five years ago
it was 20 seconds, now it is real time.
What we need to do now is to be sure that the computers and
the orientation of the slices that you want to get from the
heart can be done much faster.
That is what we are doing. It is part of our program
research, and it is done in the hospital across the street from
the NIH at the Suburban Hospital.
Mr. Porter. The last time I asked this question it was
unclear what the answer was, but do we know if there are any
side effects from MRI?
Dr. Lenfant. No.
Mr. Porter. Is there any test to----
Dr. Lenfant. I am not aware of any. I am not aware of any
side effects.
Mr. Porter. Are there any studies that have been done to
determine that?
Dr. Lenfant. I am sure it has been done, but I must admit
it is not my field so I do not know. All I know is that there
is an effect on your watch and your credit cards if you were to
go through with them.
RESEARCH OPPORTUNITIES
Mr. Porter. You may have already answered this in an
anecdotal way, but what research opportunities have you been
able to pursue with the increases that NHLBI has had in the
last two years that you would not have been able to pursue if
the increases had not been there?
Dr. Lenfant. That is certainly one.
Mr. Porter. That is what I assumed.
Dr. Lenfant. Another one is the application of the genomic
research that has been supported by our colleagues in the
Genome Research Institute.
We also have initiated a number of clinical trials,
developing actually a new approach to clinical trials which
brings out results much more quickly, and the institute has
multiplied the number of clinical trials, and more are in the
process of being developed.
So I think what has been happening--and I have a list of
specific initiatives that have been started during that period
of time. What we have done is to take full advantage of all the
new technologies and new approaches which have been developed
in other fields--in molecular genetics, in cancer research--and
we have imported that into cardiology and pulmonary medicine
and hematology when needs be, and we are really increasing the
process of translating all that into clinical applications.
One thing, Mr. Chairman, that I would like to comment upon
is that in some fields we know a lot, but I have to say that
the gap between what we know and what is being applied is
widening, and we are aware of that and using all kinds of
approaches--demonstration studies by way of clinical trials,
demonstration studies at the community levels, and public as
well as professional education. We are trying to compensate for
that and to basically speed up the application of what we know.
Mr. Porter. Thank you, Dr. Lenfant.
Mr. Hoyer?
Mr. Hoyer. Doctor, if I understand that answer, we have
greater knowledge today, and the gap between that knowledge and
the application of that knowledge to patients is greater today
than it was ten years ago?
Dr. Lenfant. That is correct. Yes.
Mr. Hoyer. Presumably, that is because we have so much more
knowledge today----
Dr. Lenfant. Yes.
PATIENT INFORMATION ACCESS
Mr. Hoyer [continuing]. But the practitioners are having
difficulty keeping up with that knowledge and applying it.
When I first went on this committee in 1983, I discussed
with the National Library of Medicine--I do not know that I was
certainly one of the first to discuss it, but it was of
interest to me--about having computer access--which now, of
course, is the Internet--computer access to information at the
National Library of Medicine so that the most rural doctor
would have on his or her desk the ability to access the
information to which you now refer.
It seems to me that we are spending a lot of money,
properly so, coming up with, obviously, both diagnostic and
treatment modalities that are far superior to what we had ten
years ago and five years ago, apparently, and I am sure of real
concern to those who are going to get sick, that they do not
have all the information available in their practitioner's
office or the hospital to treat them.
How big a problem do you think this is?
Dr. Lenfant. Well, first of all, I should tell you that
there are many physicians today who have computer facilities on
their desk or in the back room where they can go and get the
information as needed.
I think you have put your finger on what I consider to be
the real issue, which is that research has been extraordinarily
successful. We learn a lot and we learn fast what could be
applied. And it is very difficult, and that requires some work
and new approaches on our part, I think, to speed up the flow
of that information from the physician to the parties.
At the same time, we have to recognize information
overload. In addition, the practice of medicine, for a variety
of reasons which really I cannot comment upon, has become much
more complex in terms of insurance coverage and this thing and
that thing and all kinds of conditions which have made the
practice of medicine a little bit more complicated.
Mr. Hoyer. Doctor, obviously I have some questions that
relate directly to your institute, but I am interested in this.
Let us say I am a doctor practicing in a relatively rural
area and do not have a lot of colleagues with whom to interface
on a particular set of symptoms that confront me. Do I have the
capability of, in effect, logging them in to my computer, or e-
mailing to a central site, either at NIH or some place else, or
maybe even in my State society, and, in effect, getting help
with that diagnosis, based upon these symptoms?
Dr. Lenfant. Yes.
Mr. Hoyer. Do I have that?
Dr. Lenfant. Yes. NIH has the--Dr. Kirschstein can probably
explain that much better than I, because it is a centralized
function at NIH at the Library of Medicine.
Mr. Hoyer. It seems to me, quite obviously, in terms of all
this money we spend, ultimately it is an individual patient and
their treating physician or physicians that we want to make
sure have all that information to treat them with the best
information possible.
Dr. Kirschstein. Mr. Hoyer, the National Library of
Medicine--and when Dr. Lindberg is here you can get more
details from him--has a very wide set of abilities to provide
information to physicians very quickly through PubMed Central,
through MedLine and so forth. What it does is allow people to
put in symptoms or drug names or something of the sort and then
get the literature and search through the abstracts of the
literature.
This will be increased soon something that I described on
Tuesday, which is going to be the clinical trials database,
which was legislated through the FDA Modernization Act, and
that has just been set up. It is about to be launched, and all
clinical trials for various diseases, whether they be Federally
sponsored or privately sponsored, will be eventually entered
into that database for physicians to access.
Mr. Hoyer. Thank you. I will pursue that further with Dr.
Lindberg.
Dr. Lenfant. May I add that I am sure each institute does
its own page now. We have a great number of clinical trials
which were supported. Each time the outcomes of these clinical
studies are known, we put them on our home page, which is very
well known and recognized in the country. I think we get
thousands, tens of thousands of hits each month, so people see
these things.
ASTHMA
Mr. Hoyer. Thank you.
Let me pursue a little bit of your particular institute's
focus.
Asthma--I am somewhat perplexed by--somebody has come into
our office to ask questions about this, and the background is
this: according to the information I have, the recent
situations on the prevalence of asthma reveal that 11,100,000
people in the United States reported having asthma, which is
then said to be a 25 percent reduction from a percentage of
14,900,000 reported in 1995.
Now, that was contrary to the information that I had, where
I thought the incidence of asthma was increasing. Now, maybe it
is increasing among a particular cohort, but in a more broadly-
based, where children are experiencing more asthma but adults
are not.
In any event, can you explain this reduction?
Dr. Lenfant. Yes. What you are referring to is an
unfortunate artifact, I would say, which results from the way
the National Center for Health Statistics has changed the
question in the first survey relative to the second survey.
The second survey was somewhat more restrictive in the kind
of answer that people could give, and that is what has led to
the reduction that you just mentioned.
The fact is that, irrespective of all that, we do know
that, indeed, in this country and in other countries, mostly
western countries, the prevalence of asthma is increasing.
We do know it from other studies and surveys which have
been done by other organizations or agencies.
But what you are mentioning here is a very interesting
phenomenon, which is a change in the definition of the
question, and that, of course, always causes a problem when you
look at trends.
The World Health Organization, for example, each three or
four years has a different classification of disease, and then
you see the number go up and down for that reason.
Mr. Hoyer. Thank you, Doctor. I have other questions, but I
will wait for the second round.
Mr. Porter. We will have a second round.
Thank you, Mr. Hoyer.
Mr. Jackson?
MINORITY DATA COLLECTION
Mr. Jackson. Let me begin by thanking Dr. Lenfant for your
presentation today before our subcommittee.
The President's fiscal year 2001 budget for NHLBI is a
little over 2,000,000,000, an increase of about 108,000,000,
and 5.5 percent above the fiscal year 2000 level.
Included in this total is 40,000,000 for the following NIH
areas of special interest--I want to say NIH areas of priority,
as opposed to special interest. Whenever I hear that word, I
feel like it is a program that is about to get cut.
Health disparities, $6,000,000; new avenues for the
development of therapeutic, 16,000,000; new approaches to
pathogenesis, 7,000,000; new prevention strategies against
disease, 7,000,000; computers and advanced instrumentation,
4,000,000.
Before I ask my question, I want to first acknowledge that
Dr. Lenfant has been quite a champion for addressing some of
the central inquiries that I have raised thus far, Mr.
Chairman, on the issue of disparities in his area of expertise,
and I want to begin by congratulating you for the efforts that
you have made and again to thank the acting director of NIH,
Dr. Kirschstein, for her stick-to-it-ness and commitment in
this area.
My question, Dr. Lenfant, is a question about data
collection. Obviously, your department, based upon its budget,
has a commitment in this area. I am wondering, has your office
collected any data on the prevalence of heart, lung, or blood
diseases amongst Native Americans, Latino Americans, or
geographical data on the prevalence of these diseases, let us
say in Appalachia or in the south by region, or in, for
example, the former rust belt of the Nation.
Dr. Lenfant. Yes. We have several programs for data
collection, and we have this information. I could provide it,
if you wish, for the record. But we know pretty well where the
highest prevalence and incidence of cardiovascular or pulmonary
or blood diseases, as the case may be, are in the country, and
we know also pretty well what the reasons for these variations
between States, for example, might be.
It is interesting, Mr. Jackson, that you asked this
question. Just yesterday, I believe, there was a report that
was published by the CDC and the University of West Virginia
which addresses that very issue, which is the variation of the
differences in prevalence of heart disease in women, especially
African American women in various parts of the country.
But the short answer to your question, yes, we do know this
data and we use them for many of our programs.
Mr. Jackson. Thank you, Dr. Lenfant.
I am wondering, does your institute collect economic data
on the prevalence of these type of illnesses amongst, for
example, the less affluent in our society who might find
themselves working in Appalachia in a coal mine or in southern
Illinois in a coal mine, but, compared to, let us say, someone
in Silicon Valley who might be into computer programming and
therefore never come into contact with an environment that
might create heart, lung, or blood type illnesses?
Dr. Lenfant. No. We do not collect these data because, by
and large, I would say they are well recognized and we know
about these data.
Our way to addressing that is somewhat indirect. For
example, if we think that we need to have a demonstration
project or an educational program, a special action, that is
often where we target it, in these areas of low socioeconomic
status.
For example, just a few days ago we made the awards for a
program on the control of asthma in communities. We made seven
awards, and all seven awards are in low economic status areas
in the country.
JACKSON HEART STUDY
Mr. Jackson. I guess that leads very gracefully into my
next question.
I am wondering, in light of your own testimony today that
there is an increasing prevalence of heart, lung, and blood
type diseases amongst African American women, and that, based
upon certain economic data where someone might find themselves
economically situated in the society based upon their
education, based upon what is available to them in terms of
employment, I am wondering, in light of that information, does
your institute then specifically look for research proposals
that will study even further the prevalence, let us say,
amongst that new data in those particular categories?
Dr. Lenfant. We do that. An example that I mentioned is a
study that we have initiated in Jackson, Mississippi, which is,
I believe, a unique study where--you may have heard about
Framingham, which is a national treasure--that is the way we
like to look at it--because of all the information that has
come from that study.
Basically, Jackson, if you want, is a Framingham South,
where the entire cohort is African American. We have a cohort
of 6,000 men and women who are going to be followed for a long
period of time. Our initial award is for seven years. I am sure
that will be continued after.
Basically, at the end of all that we will know a great deal
about not only the status as it is at the end of the seven
years, but also it will give us a tool to do something about
it.
MINORITY MEDICAL SCHOOL RESEARCH PROGRAM
Mr. Jackson. I also understand, Dr. Lenfant, that there is
some discussion at NHLBI about a minority medical school
research program. I am wondering what the scope of the concept
is and how will it work.
That is my final question.
Dr. Lenfant. That is correct. It is something that we
intend to initiate in the year 2001. The issue, Mr. Jackson, is
really two-fold. First of all, there is plenty of evidence in
all areas that if you want to address a health issue which is
specific to a group, it is better to have physicians and
researchers which are part of that community to work on it.
Therefore, one of our goals is to be sure that there is a
program for all the same minority schools and universities of
individuals who will become interested in biomedical research.
The second thing is that we talk here about clinical trials
and clinical studies. One of the great difficulties that we
have at our institute--and I am sure it is shared by other
institutes--is to recruit a number of participants from all the
groups for which you want to get an answer, the different
ethnic groups. That also requires the participation of
physicians and researchers which are from the same community.
So that is the second goal.
And so the overall goal of this program is to develop a
research interest, but also interest in this community and
actually in these institutions and medical schools, and that
actually is the second phase of a program that we started three
or four years ago but which is reaching full maturity this
year, and that is to establish a research base by providing
resources to recruit very distinguished scientists into these
institutions.
We have six or seven institutions, historically black
colleges and universities, which have been the recipients of
this program.
Mr. Jackson. Let me thank you, Dr. Lenfant, and also
congratulate you once again for your very thoughtful approach
to these issues and this area.
Thank you, Mr. Chairman.
Mr. Porter. Thank you, Mr. Jackson.
Mrs. Northup?
GENE THERAPY
Mrs. Northup. Yes. Thank you, Doctor.
Doctor, I would like to talk to you specifically about the
gene therapy approach that you talked about here, and also some
other approaches to some of these problems.
I am not objecting to the gene therapy. I just, in
particular, have become increasingly aware that there are new
approaches, for example, to sickle cell anemia, actual cures
possible that are related to bone marrow transplants, reducing
the mortality from those by not having 100 percent, not killing
the patient's bone marrow 100 percent so that they are less at
risk, and by, at the same time, using the donor's bone marrow
that may not be perfectly matched, because there are ways that
maybe, instead of six exact matches, you can have four exact
matches.
This has shown to be so successful in the early trials that
I am concerned about two things: one of them, continuing to
pursue mostly just a gene therapy approach to it instead of the
bone marrow transplants; and, number two, whether we are
funding the clinical trials necessary so that we can, as
aggressively as possible, make this treatment widely available
if it proves to be as successful as the initial approaches to
it.
Dr. Lenfant. Yes. Well, your question is absolutely
fascinating and very important to us because these are
activities in which we are very deeply involved.
It is true, indeed, and I can confirm that the reports of
partial ablation of the bone marrow works very well and has
worked very successfully. In fact, in our internal programs we
are pursuing that approach in a number of cases.
The issue of bone marrow transplantation either with
``mature cell'' or stem cell is also an approach and a
technology which is really blossoming at this time.
We do have clinical trials, but these are partial, small
clinical trials, and we do recognize very well with, in fact,
the Cancer Institute, that what is being done is not up to
meeting the needs as we see them.
Mrs. Northup. I think what my question is, though, is that
gene therapy may, in the end, provide answers to things such as
sickle cell, and I am glad we pursue that. But right now in
front of us seems to be--I mean, as I understand the partial
ablation, one of the reasons we did not use bone marrow before
is because with full ablation the death rate was so high that
children had to get so serious that we would take a chance, and
then sometimes you could not reverse the damage the disease had
done all along the way.
But now, with partial ablation and the safety that that
brings, there is a chance that right in front of us in the near
term we could provide an alternative that would avert the
strokes and the other damage to this population.
And your very term, ``we have a few small clinical
trials,'' I think is what worries me. My understanding is that
they are under-funded, they are not at the level that pays for
the cost of treating the patients that are actually in the
trials.
While we invest in long-term, fabulous biomedical research
that will solve this, should we not, in the meantime, invest
moving this apparent solution or possible solution ahead?
Dr. Lenfant. Let me first reassure you by saying that I am
not aware of any attempt to use gene therapy in sickle cell
disease in this country or anywhere in the world.
Mrs. Northup. Well, I thought it said in your
presentation--when it talked about programs, excellence in gene
therapy, I thought it said for cases such as sickle cell.
Dr. Lenfant. To explore the avenue to eventually do it, but
that is not being done. And I can also tell you that our
commitment and investment in bone marrow transplantation is
very large.
I was about to tell you that, jointly with the Cancer
Institute, we are, at present, exploring or pretty much
deciding how to conduct and develop a network for bone marrow
transplantation in this country. We do it with cancer because
clearly malignant blood diseases are the prime target for this
therapy, but there are also a number of non-malignant diseases
which would benefit, one of them being sickle cell.
I would like to say, though, if I may, that the major
answer, sometimes reports on bone marrow transplantation here,
another there, on sickle cell patient with great fanfare. What
needs to be known is that it is still a very dangerous therapy,
even with the caveat that you have mentioned, partial ablation
and the ability to have a match for four or five antigens
instead of the six.
Mrs. Northup. Well, of course, just the fact you have
sickle cell is very dangerous----
Dr. Lenfant. Yes.
Mrs. Northup [continuing]. Because it results in death.
I point out to my colleagues, it is 100 percent African
American.
Dr. Lenfant. Yes.
Mrs. Northup. And the occurrence of the other diseases that
are similar that could benefit from this include--well, I am
drawing a blank, but there are a number of other ones.
Dr. Lenfant. Cooley's anemia, for example, or Fanconi
anemia.
Mrs. Northup. Lupus? Would lupus be an example, or would
that be too removed?
Dr. Lenfant. No.
Mrs. Northup. Well, there are a number of other diseases.
The incidence, I believe, in African Americans is much higher
in these areas, and the fact that there is a possibility of a
breakthrough that even healthy children with sickle cell would
maybe begin to opt for it--as I understand, they actually have,
in certain cases, in certain families, or asked for it--seems
to me that, rather than look way down the line at gene therapy,
we should move these studies ahead, so that if they have the
benefits that they seem like they might have, they are within
reach.
Dr. Lenfant. I really wholly agree with you. I can only try
to reassure you by saying that that is what we are doing.
Mrs. Northup. Okay.
Dr. Lenfant. We are working very hard to bring bone marrow
transplantation and stem cell transplantation to where it is
needed. But at the same time, I want to underscore that it is
not an approach which is free of very, very serious
complications.
Mrs. Northup. Well, I look forward to seeing the review of
the statistics that show what the success and failure rate is,
what the level of danger is, especially as we begin to reduce
the percentage of ablation that--you know, whether it is 90
percent or 60 percent also might be the difference between the
patients making it through. But my understanding is we have
gotten it low enough with good results that it is possible that
it will be a safe procedure.
Mr. Porter. Thank you, Mrs. Northup.
Ms. Pelosi?
PUBLIC ACCESS TO DEFIBRILLATORS
Ms. Pelosi. Thank you very much, Mr. Chairman.
Doctor, welcome. Thank you for your good work and for your
testimony today, to all of you.
Dr. Lenfant, clearly large Federal investments in health
care research and prevention can improve health. We all
stipulate to that. In your testimony, you discuss the
effectiveness of installing automatic defibrillators in public
places to rescue victims who need the assistance. Could you say
a little more about the cost and the benefits of this approach,
including the financial investment that would be required? And
if we were to identify fatal arrhythmias through T-wave
alternans and young athlete screening, what would be the cost
and the benefits if we targeted that way?
Dr. Lenfant. Let me first speak about the defibrillators
and public access to defibrillators.
There is, indeed, a program which is being set up and some
research, as you put it, to establish the efficacy or lack of
efficacy, whichever it is going to be, from this approach,
which basically is to put defibrillators in public places. Our
study is focusing on retirement homes and assisted living
facilities because that is where you have the largest number of
individuals who may experience a sudden cardiac arrest.
The efficacy is not known because it has not been done in
systematic ways. We have anecdotes of that being done on an
airplane, and sometimes it works, sometimes it does not work.
Just a few days ago there was a report in the national news of
a case some place--I forgot where it is--where it did not work.
The patient did not recover.
The issue is largely one of the training and the experience
of those who administer the electric shock.
I cannot tell you either about the cost effectiveness nor
the efficacy of that.
With regard to the cost effectiveness, I can, however, say
that if it was to work, if it was demonstrated that it works,
there will not only be a great social but also financial
benefit from that because if you have an individual who has a
sudden cardiac arrest and whose heart is not made to work very
quickly, but eventually it is done, meanwhile, the patient may
develop some cerebral damages and we find ourselves with a
terrible situation which, of course, is very heavy in
consequences.
You mention in your questions two approaches which are
being now developed and, in fact, have been demonstrated to be
quite effective to predict individuals who may be at risk of
developing a cardiac arrest.
The return to regular, normal heartbeat after exercise is
extremely important for young individuals who engage in very
active sports and things of that sort. It is an unfortunate
case that very often we hear of basketball players or football
players or whatever who literally drop dead during a
performance because nobody knew that they may be at risk.
That approach that you mentioned may be a way to detect
these individuals and keep them from engaging in such
activities.
The other approach that you mentioned, which is to be able
to detect abnormalities in an electrocardiogram reading is also
quite effective. It has been demonstrated to be working well.
However, at this point in time it is not generalized.
But there is great prospect here.
Ms. Pelosi. What does a defibrillator cost?
Dr. Lenfant. I think they go for maybe a couple of thousand
dollars, I think.
Ms. Pelosi. But you said the key is the ability of the
person?
Dr. Lenfant. That is really the issue, because, you know,
if you have somebody who, say, passed out, and people think
that that is a cardiac arrest when it is not, and you start
defibrillating the person, then you can cause the heart to
stop. So you have really got to know what you are doing.
KIDNEY DISEASE
Ms. Pelosi. I understand that hypertension is the second
leading cause of American kidney disease, second only to
diabetes. As you know, hypertension is more prevalent in the
minority community.
Last year you reported on the release of the clinical
guidelines on the identification, evaluation, and treatment of
overweight and obesity in adults. This report was a joint
project of the NHLBI and the National Institute of Diabetes,
Digestive, and Kidney Disease.
Can you identify for the subcommittee specific joint
research projects of the two institutes that relate to kidney
disease? Are there any other plans for additional joint
projects with the NIDDK ahead to discover more about linkages
between hypertension and kidney disease?
Dr. Lenfant. Ms. Pelosi, at this point in time we have no
study which is specifically on kidney disease. However, it so
happened that just a few days ago I was discussing the prospect
of developing such studies with the newly-appointed director of
that institute.
However, the two institutes are supporting two major
clinical trials in diabetic patients in whom, of course, kidney
complications, kidney disease is a very serious complication,
and these are huge clinical trials. The one, which the Diabetes
Institute has the lead, focuses on a population of obese
diabetics. The one that we have does not focus on obese
diabetics, but these patients, as well as those from the
clinical trial, supported mainly by the Diabetes Institute, are
really candidates, if I may say so, for kidney disease.
So there is work which is ongoing in diabetes patients.
Ms. Pelosi. Thank you, Dr. Lenfant.
Mr. Porter. Thank you, Ms. Pelosi.
Mr. Bonilla?
DIABETES
Mr. Bonilla. Thank you, Chairman.
Dr. Lenfant, good to see you again. I have only one
question this morning that relates to the things you are
working on with diabetes. As you know, it is a problem that
many of us on the subcommittee are trying to draw more
attention to.
I understand there are four major clinical trials on
prevention of cardiovascular disease in persons with type two
diabetes. Could you please explain how these trials differ from
one another and what you might expect to gain from each one?
Dr. Lenfant. Two of them I just referred to in my answer to
the previous question. Let me repeat the essentials of this
response.
One of them is supported jointly by the two institutes--the
Diabetes Institute and us. The Diabetes Institute is the lead
institute, and that focuses on obese diabetic patients.
Ours, where we have the lead, but there is a participation
from the Diabetes Institute, does not focus on obese patients.
The purpose of this one is to prevent the development of
cardiovascular complications, which, as you know, are the main
cause of morbidity in these patients.
The third clinical trial, which is supported exclusively by
our institute, is to prevent or interrupt the evolution of
cardiovascular complications in these patients, and the idea
here is to compare an intense medical approach with an
interventional approach, which would be angioplasty in these
patients.
The fourth clinical trial, in which we are involved in a
more advisory way than a financial one, is largely supported by
the Veterans Administration. Here, again, it is on the
prevention of diabetes in patients with elevated glucose.
Mr. Bonilla. Thank you very much, Dr. Lenfant. It is always
good to see you. I appreciate your hard work at the institute.
Thank you.
Dr. Lenfant. Thank you.
Mr. Bonilla. Thank you, Mr. Chairman.
Mr. Porter. Thank you, Mr. Bonilla.
Dr. Lenfant, we have Dr. Slavkin following you today, and
we are running low on time.
I am going to ask whether any member of the subcommittee
has one more question perhaps that they feel they would like to
ask now.
Mr. Hoyer?
Mr. Hoyer. I will submit the questions. I know the time is
short.
Mr. Porter. Ms. Pelosi, any further questions?
Ms. Pelosi. No thank you, Mr. Chairman.
CORONARY ARTERY DISEASE
Mr. Porter. I am going to ask one, myself, so please feel
free. I have a question that I find interesting that my staff
prepared, and that is this one.
Studies have suggested that relatively low bone mass tends
to be associated with relatively high mortality from coronary
artery disease and stroke.
Yesterday we heard from Dr. Alexander that osteoporosis is
a pediatric disease with geriatric consequences, because by age
17, 90 percent of adult bone mass is established. It sounds
like coronary artery disease and stroke could also be called
pediatric diseases with geriatric consequences. Would you agree
with that?
Dr. Lenfant. Well, to that I will say that we know for a
fact that coronary artery abnormalities or any artery
abnormalities develop during the teens and some time before. We
know that. We have done extensive studies. In fact, that
started at the time of the Korean War, when many of these young
soldiers who died and had autopsies, it was found that
sometimes in their late teens and early 20s they had
considerable lesions in their arteries, and that brought the
focus on the early prevention of that state.
So I think I would not go as far as the way it has been
said, but I would certainly comment on the fact that it is
critical that good healthy behaviors start very early in life
to prevent further complications.
Mr. Porter. Dr. Lenfant, what is the connection between
bone mass on the one hand and coronary artery disease, or is it
just a correlation?
Dr. Lenfant. At this point in time, it is an association.
It is true that a number of epidemiological studies have shown
that there is, indeed, an association between osteoporosis in
adults--not in middle-age individuals--and coronary heart
disease.
That is really what has triggered all the interest that you
are hearing now, that if you treat coronary heart disease with
statin--you know, this wonderful drug that really prevents the
development and controls the evolution of coronary heart
disease--if you treat patients with osteoporosis for the
coronary heart disease with statin, you have a reversal of the
osteoporosis.
And so the mechanism at this time of that is not known yet,
but we have an observation which is extremely interesting.
In fact, one of the things that I believe I have in my
testimony is that, jointly with the National Institute on
Arthritis, Musculoskeletal, and Skin Disease, we do intend to
develop a program next year to study the mechanisms--that is,
the basic science--of that, but also the clinical implications,
which are extraordinarily important.
Mr. Porter. So the statin can both prevent further plaque
in the arteries and maybe even reverse it, as well as reduce
the osteoporosis?
Dr. Lenfant. Correct, sir.
Mr. Porter. Fascinating.
Dr. Lenfant. It is. It is an amazing observation, which
clearly has moved to the forefront this year.
Mr. Porter. Well, Dr. Lenfant, thank you for the absolutely
marvelous job you do at NHLBI. We very much appreciate you.
I have so many questions I would love to ask, but
unfortunately we just do not have time. We will have to submit
them for the record. You are doing a marvelous job there, and
we very much appreciate it, sir.
Dr. Lenfant. Thank you very much.
Mr. Porter. Thank you.
The subcommittee will stand briefly in recess.

the record:]

Institutes of Health with the National Institute of
Environmental Health Sciences, and I am pleased to welcome Dr.
Kenneth Olden, the Director.
Dr. Olden, it is always good to see you.
Dr. Olden. Thank you.
Mr. Porter. How many years have you been Director now?
Dr. Olden. Soon to be nine years.
Mr. Porter. I was going to say----
Dr. Olden. It has been a long time. [Laughter.]
And I have enjoyed every one of them.
Mr. Porter. Not that long.
We think that what you do is very, very important and we
are always pleased to have you come and tell us the progress
that you are making and how you are spending the public's
money.
Dr. Olden. Thank you very much.
Mr. Porter. So, why don't you introduce the people that you

Francine Little, who is a new member of our staff and who is
the Associate Director for Management; Dr. Sam Wilson, Deputy
Director; and you know Dr. Kirschstein and Mr. Dennis Williams
from the Department.
ENVIRONMENTAL HEALTH DECISION MAKING
Mr. Chairman and members of the Committee, there has never
been a more exciting time in environmental health research, so,
I hope that today I can convey the urgency and talk about the
opportunities and the enthusiasm in the field. All of this
excitement and enthusiasm has been generated because we now
have the technologies and tools to answer many of the important
problems in environmental health research.
Our products are used for two purposes, not only to make
public health policy decisions in terms of prevention,
diagnosis and treatment of human illnesses, but our products
are also used by regulatory agencies to make environmental
health policy decisions--two very important activities.
Over the years as I have appeared before this Committee, I
have consistently been an advocate for better science for
better environmental health decisions and better science to
prevent chronic diseases such as cancer, Alzheimer's and
Parkinson's.
Today I want to continue in that vein. I want to comment
again on the state of the science that we use in environmental
health decision making, and about the opportunities that we
have to change that scientific base. Now, when we go to buy a
car or a house the one thing that we spend a lot of time doing
is gathering information. So, information is important in our
personal lives and it is also important to the Government in
terms of making sound public policy. For example, if we are
going to buy a house or a car we consider things like
reliability, safety, and resale value and the investments that
we are making are very small compared to the kind of investment
that we make when we set an environmental health regulatory
standard.
Also, the consequences of buying a house or a car are much
less significant than the decisions as to what is the right
level of exposure to allow the American people to be exposed
to. So, the decisions that we make about environmental health
cost the nation hundreds of billions of dollars in terms of
regulatory compliance and it also could cost the nation in
terms of human suffering and in terms of the health of the
American public if we do not make the right decisions.
Now, when I appeared before this Committee over the past
couple of years, I have indicated that there are nine critical
investments that we need to make to improve environmental
health decision making. Now, on the exhibits that I have over
here in the corner I have identified only four of those areas.
[The information follows:]
Dr. Olden. Now, you can visualize that scheme in that
exhibit as having nine boxes, Scheme A, as being nine boxes
with nine question marks. In other words, issues that we do not
know. Usually, in environmental health decision making, we have
information on environmental quality that we can associate with
specific diseases. Usually we have very little information on
the toxicity of those chemical, physical and biological agents.
We almost never have information on the mechanism of action of
those chemicals. We know very little about exposure and we know
very little about susceptibility and there are a number of
other issues that we also don't have information on that are
not shown.
Now, the debates about risk assessment usually revolve
around one's confidence in Scheme A versus Scheme B. In other
words, to what level must we fill in all of those question
marks before you are satisfied, what is your level of comfort
that we are making the right decision based on Scheme A versus
Scheme B.
Now, no matter what that is, I maintain that all of us
would be much more comfortable if we had eliminated many of the
uncertainties and many of the question marks that are evident
in Scheme A versus Scheme B. So, what we are trying to do at
NIEHS is to generate the data base to fill in the information
that exists between exposure and human diseases.
Even though we don't have the information, regulatory
agencies must still make decisions, so they resort to the use
of default assumptions. Default assumptions, because there are
uncertainties and there is an absence of data. They also use
the precautionary principle in arriving at a regulatory
decision. So, we want to generate the science so that we can
make decisions without doing that.
INDIVIDUAL SUSCEPTIBILITY
Now, it was okay 10 years ago for us to make decisions on
the basis of default assumptions and the precautionary
principle and we should still use them in cases where we have
to. However, I maintain that we now have a sufficient knowledge
base. We know how to ask the right questions and we have the
tools to provide answers to those questions. I am told by my
friends who are practicing physicians that one of the most
common questions that they are asked is. ``Why me, Doc?''
[The information follows:]
Dr. Olden. In other words, why do I have lung cancer,
berylliosis, or asbestosis, while my friends who had similar
exposures don't have these illnesses? Well, one answer may be
differences in an individual's susceptibility.
You will recall a few years ago, two years ago in 1997, we
introduced at this hearing the development of the Environmental
Genome Project to determine the genetic basis for differences
in susceptibility to environmental exposures. Now, even though
we know that we all are not identical, we still regulate as if
one size fits all.
[The information follows:]
Dr. Olden. You can imagine a manufacturer of shirts, for
example, who made the assumption that one mold, one size fits
all. There would be no opportunity for that person to reinvest
profits or to consider expansion because there would be none.
So, we are in the same bind in environmental health decision
making. So, what we are trying to do with the Environmental
Genome Project is to determine what is the genetic basis for
differences in susceptibility to environmental exposures.
Since we announced the Environmental Genome Project in
1997, we have discovered many genes--as a matter of fact they
were being discovered prior to our announcement but the pace
has been greatly accelerated--we have discovered many genes
responsible for differences in susceptibility and I can say
this is now probably one of the most exciting areas in
biomedical research.
ELIMINATING UNCERTAINTIES
Today I want to announce two new initiatives. Both
initiatives will help us in eliminating some of those
uncertainties or some of those question marks that you see in
Scheme 1 in the first exhibit. First, we want to expand the
Environmental Genome Project by developing university-based
mouse genomic centers to construct animal models to mimic the
susceptibility genes that we will discover in the Human Gene
Resequencing Initiative. These genetically-modified animals--
they would be models of human susceptibility--these
genetically-modified animals will be made available to
scientists and investigators worldwide so that we can finally
conduct the experiments to clarify the role of genetics in
environmental susceptibility. The results from these studies
will profoundly alter the practice of medicine and
environmental health decision making in this country.
Secondly, I want to announce the expansion of our efforts
to develop high throughput technologies for carcinogenicity and
toxicity testing. In my testimony before this Committee in
1997, I updated you on our efforts to develop and validate
transgenic animal models for use in carcinogenicity testing
using high throughput approaches. In other words, I said the
current approach using rodent bioassay is too costly and it
takes too long to perform. Well, we have had a lot of success.
And, again, there are now many papers and it is an intensive
area of research in many laboratories to use these transgenic
animal models to identify carcinogen and toxicants in a much
more rapid manner, fashion.
The cDNA microarray technology is really the second
generation of high throughput approaches. I mentioned two years
ago that even though I was excited about our success with
transgenic animal models, that new high throughput approaches
would be on the horizon very soon. Today we believe that that
approach is here. And that is the use of cDNA microarray
technology.
[The information follows:]
Dr. Olden. Now, the expectation is that each class of
toxicants will alter the expression of genes in the cell,
generating what we call a gene expression pattern. So, if you
expose cells to a given class of toxicants there should be an
expression pattern unique to that group of chemicals. So, by
development of a signature data base, which is of all known
toxicants--this is comparable to the FBI fingerprint data
base--we can screen the universe of chemicals to identify
agents whose signature patterns match one that is already in
existence in the data base, just as the FBI can identify an
offender from a population of 200 million with a very high
degree of certainty. We believe that we can use a similar
approach using a signature pattern of gene expression to
identify those chemicals that are going to be toxicants.
The data base will not only contain all the chemicals in
commercial use in the United States and the world, but it will
also contain the signature patterns of chemicals that failed in
industry pre-market testing, because those are also important.
So, we formed a partnership with industry and the Food and Drug
Administration to get access to those chemicals that never made
it to the market place because of toxicity. If we have the data
base on the 85,000 chemicals in commercial use that are
toxicants, as well as those from the various pharmaceutical
industries then we believe that we will have an appropriate
data base so that we can match an unknown.
Now, what are the advantages of this approach? First, it
can be automated so we could screen chemicals 24-hours a day,
7-days a week using robotic technologies. We could screen
thousands of chemicals and we could involve thousands of genes
and we could do it at low-cost, in fact, dirt cheap compared to
what the 2-year rodent bioassay costs. It probably would not
require the use of animals and the mechanism by which the gene
expression signatures are generated also reveals something
about mechanisms. So, already we would know a lot about
mechanism. Also, the interpretation of the results would be
less subjective. In other words, it would be less dependent on
pathological examinations of the tissues.
So, we believe that we can compare the signature pattern of
an unknown toxicant or suspect and match that with the
signature pattern of a known and identify with almost absolute
certainty that this chemical is a toxicant and operates by a
specific mechanism.
In closing, Mr. Chairman, let me say that we have the
opportunity to fundamentally change toxicology as we know it
today. And I hope the Committee shares my enthusiasm for doing
so.
Now, Mr. Chairman, let me finish by congratulating you on
20 years of distinguished public service and I wish you good
health and happiness in the years ahead. The President's budget
request for NIEHS for fiscal year 2001 is $460,971,000. And I
would be pleased to answer any questions that you might have.
[The written statement of Dr. Olden follows:]
CDNA MICROARRAY TECHNOLOGY
Mr. Porter. Thank you very much, Dr. Olden.
What do we call this new--it is high throughput?
Dr. Olden. It is cDNA microarray technology. It has been
around.
Mr. Porter. All right. We will just call it what it says
there.
Dr. Olden. Yes.
Mr. Porter. All right, you are not yet doing this now; is
that correct?
Dr. Olden. We are doing it.
Mr. Porter. You are doing it.
Dr. Olden. Yes. It was developed in the Human Genome
Project in the NIH and the entire NIH enterprise is interested
in this technology for a number of reasons. We are interested
in it from a toxicological point of view. We realize that this
is a very powerful tool for toxicology to advance our capacity
to identify toxicants and carcinogens in a very fast,
economical way. So, we have taken the lead in the NIH to
develop it for that purpose but other institutes are investing
this technology for other purposes and we are doing it in
partnership with other institutes.
But we are focusing on the toxicology aspect of the
technology.
Mr. Porter. All right, now, would you do this by grants or
by contract or intramurally or----
Dr. Olden. Well, what we are proposing at this point,
Congressman, is to create a resource center some place. This
technology is very expensive and also you don't need one in
every laboratory and at every university. You do need centers
that know how to do it because it is also a very difficult
technology and you need to have expert people who really know
informatics and other aspects of the research.
So, what we are proposing at this the moment is to provide
this to the scientific community as a resource. We are
proposing to create centers, one at NIEHS, which we already
have up and running. Our hope is that we will also have four or
five around the country, such as in California, so that all our
investigators who are interested in this toxicology would have
access to it.
We are, however, going to have a national data base. The
only place that the national data base will exist is in the
NIEHS because we have the partnership with industry and Food
and Drug Administration and we have access to many chemicals
that an investigator in a university would not have access to.
So, it is important that we develop the national data base.
TRANSGENIC ANIMALS
Mr. Porter. How are you doing this now except for this? In
other words, haven't you used some kind of transgenic rodent
experiments?
Dr. Olden. Yes, we have. That was the technology that I
described to you last year or two years ago when we gave you a
progress report.
Mr. Porter. Yes.
Dr. Olden. And we started that effort five years before
1997.
Mr. Porter. Right.
Dr. Olden. And I promised you when I came on as Director
that I thought that we could develop test systems that were
faster and cheaper, indicating at the time, that a rodent
bioassay costs us $2,000,000 to $6,000,000, and it takes 2-to-5
years to do and it uses lots of animals. That is too long, too
costly and uses 800 animals per test.
Mr. Porter. Especially if you have 80,000 different
substances to test?
Dr. Olden. Right.
Mr. Porter. Now, with the new technology, assuming you have
it up and running and you have the 4, 5, or 6 centers going,
does this obviate the need to prioritize among the substances
you are testing because you can do it so quickly you don't have
to? You can do them all?
Dr. Olden. I think that is exactly where we are moving to.
I think we can. Of the 85,000 chemicals in commercial use in
the U.S. most of them do not need testing. We know, based on
our experience, that many of them, most of them in fact, are
not going to be toxic at all. If you narrowed that down and
said, well, maybe 10,000 do need testing, we could do a general
screen for every chemical, every suspect toxicant that was in a
given class, and we could do it in a very short period of time
once we had the technology up and running and perfected. The
investment is going to be developing the technology and that is
going to require a huge data base and that is why we have got
to work together with industry and other Government agencies,
but developing the data base is going to take time.
Mr. Porter. You are going to put yourself out of business
here.
Dr. Olden. Well, the estimates are though, Chairman Porter,
that it is going to take really 10 years to put this thing in
place. But once we have got it--in other words, we have a data
base like the FBI's fingerprints--we are home free.
Mr. Porter. This is not all you will have to do though?
Dr. Olden. This is not the only thing that we have to do
but the opportunity to revolutionize toxicology is in hand and,
so, that is what I am really talking about; not doing
toxicology the way we have done it in the past. This is
exciting and it is doable.
Mr. Porter. It is certainly exciting and certainly
something that you have been looking for, for a long time.
Dr. Olden. Exactly.
CHILDREN'S HEALTH
Mr. Porter. And you have obviously found it, so, it is very
exciting to know that you have arrived there.
Can you describe the children's health research agenda that
you are pursuing and what you hope to accomplish by that?
Dr. Olden. Yes. We started a children's health research
agenda in 1993 when the Academy of Science first released a
report on the diets of infants and children with respect to
pesticide content. We started that year to invest in research,
first of all, with animal models, exposing animals--these are
rodents--during the first few weeks of life, phases that
compare to in utero exposure and embryonic and fetal
development, as well as the adolescent years. We exposed
animals to a number of chemicals, pesticides, a number of
chemicals that have estrogenic activity and asked, are there--
and we do this at low-level exposures--and ask, do we see
adverse health effects at low levels in either young children
or in utero that we would not see in an adult? That is one set
of experiment studies.
And the other is we have been supportive for a long time--
long before I got there--of research in air pollution and
pulmonary and asthma and respiratory conditions. We continued
that research. We developed 8 children's health research
centers in collaboration with the CDC and the Environmental
Protection Agency in 1998. And the focus of those centers is on
development and asthma mostly, not on cancer, and also on
cognitive and neurocognitive issues.
We are also collaborating with the National Institute of
Allergy and Infectious Diseases with respect to these diseases
and also an inner-city asthma project and this is the second
phase of the project. The first phase was to identify allergens
in inner-cities and we have identified some--cockroach
allergens, cigarette smoke and dust mite allergens. Now what we
are trying to do in New York City and 8 cities around the
country, is to develop intervention strategies based on
physician or health care provider education as well as
environmental remediation.
We also, with the National Institute of Allergy and
Infectious Diseases, have a project concerning asthma
intervention again, but it is also based on education and that
is based in Atlanta, Georgia.
We have supported for a number of years research on lead,
and we just completed a clinical trial, looking to see if we
could prevent the cognitive loss that kids experience with
blood lead levels in the range of 20 to 40 micrograms per
deciliter of blood and that has come to an end.
Mr. Porter. Would this technology tell us about the
chemicals and the exposure levels that would be toxic to
children? I mean would this lead us----
Dr. Olden. Well, in our rodent bioassays we can't test at
low doses. In other words, the doses which we are exposed to we
cannot test at, because it would take just too many animals and
cost too much to do. So, we typically test at very high doses.
So, the answer to your question is, yes, we could test at very
low doses. We could finally do low-dose exposures to see if we
got a read-out in terms of a signature pattern that would match
a given toxicant.
So, yes, indeed.
Mr. Porter. Thank you, Dr. Olden.
Mr. Hoyer?
LOW LEVELS OF EXPOSURE
Mr. Hoyer. Thank you, Mr. Chairman.
Doctor, like the other institute heads, your enthusiasm and
excitement, I think, is infectious in the best sense of the
word----
[Laughter.]
Mr. Hoyer [continuing]. To all of us.
Dr. Olden. Thank you.
Mr. Hoyer. The threshold on which all of you seem to think
we are, in terms of making very major steps forward and the
interconnectedness and interrelationship of your work, I think,
is very evident.
In your statement and just now, you were talking about low
doses. One of the issues, of course, that confronts us from
time-to-time on riders on this bill is whether or not we ought
to have various regulations that deal with low-dose exposure.
In your statement you seem to indicate that low-dose
exposure may be more dangerous than we think it is or
historically have thought it to be. Am I correct in
interpreting that from what you said?
Dr. Olden. No. I think the point I am trying to make is we
don't in most cases have the data to make that determination.
Mr. Hoyer. Okay.
Dr. Olden. I think that is unfortunate. We now have the
technologies to make those determinations and, so, I think we
ought to get the information in place so that we stop flying
blind basically.
Mr. Hoyer. Now, of course, as a practical matter, you well
realize that at Federal, State and local levels those who want
to do things that may have low levels of exposures of certain
toxics. That may indicate that we, in Government, are crazy and
are costing jobs and economic opportunities with almost--
because we are sort of relying on a no-risk environment--
objective. I guess environment is too precise a word--in terms
of your objective.
Dr. Olden. Well, I come back to the fact that I think you
can argue anything you want in the absence of data.
Mr. Hoyer. Right.
Dr. Olden. And, so, I can cite examples of where low-dose
exposure is a problem, for example, methylmercury.
Methylmercury accumulates in the body until it reaches a
threshold and there are probably a number of other chemicals,
that are lipid soluble chemicals that dissolve in fat tissue
which also do the same thing.
So, just because the exposure is low dose does not mean
that a chemical cannot bioaccumulate in humans to the point
that it does, in fact, approach the levels that we use in our
rodent models. So, low-dose, by itself, does not ensure that
there is no harm. However, I probably could cite other examples
where low-dose is not a problem.
But the issue is we don't have information to make that
determination and I think that is, in a sense, dangerous and it
is not the way that you and I would buy a house or a car. We
would want the information to make that important decision.
So, my plea is to get the information so that you and I can
be sure that the policy that you put in place is, indeed,
protecting the health of the American people, protecting the
environment and is not harming the economy because, as I
mentioned, these decisions cost hundreds of billions of
dollars, either in terms of public health or the economy, in
terms of competition for American industry. So, let's do the
experiments to answer the question.
TIME FRAME FOR NEW TECHNOLOGY
Mr. Hoyer. Remind me of what you think our time frame is in
terms of using the new technology to get it?
Dr. Olden. Well, we are using the technology now. So, we
know. In other words, we have done proof of principle. We know
that the technology will work for the objective that I
indicated.
What we don't have in place, though, is the data base. In
other words, if I wanted to screen an unknown--a suspect--I
don't have a signature pattern that is good or bad to compare
that with.
So, we first have to develop and put in place a data base
based on all of the known toxicants that we can get our hands
on and that will take a while to put in place. And, so, that is
what we are doing.
We got together with industry. We had something like 20
industry representatives around the table like this and that is
what the conversation was about. They want the very same thing
as we do.
So, what we decided to do is to partner and let's generate
this information together as soon as possible so that industry
can save money and they can get their products to the market--
these are pharmaceuticals--faster and that is in the best
interest of all of us.
And, hopefully, we can screen and they will not be toxic.
INDIVIDUAL SUSCEPTIBILITY
Mr. Hoyer. And your mouse genetic engineering will help us
get there.
Dr. Olden. Yes.
Mr. Hoyer. That may be an imprecise way to describe it.
Dr. Olden. We have a number of genomic projects in the NIH.
Almost every Institute, and we have a number of trans-NIH
projects; the single nucleotide polymorphism project that is
operated out of the National Human Genome Research Institute is
one example. What we are doing is we are identifying those
genes where there is a variation that will increase lead-to
susceptibility and/or resistance--both are important--to an
exposure to an environmental pollutant. Once we have those
genes identified, what we want to do is create animal models
containing those variations.
Mr. Hoyer. Am I correct in concluding that there may be, on
certain products, a warning at some time in the future that
states: exposure to low doses of this product will not be
harmful to 90 percent of the population?
Dr. Olden. Exactly.
Mr. Hoyer. But if you fall into this category----
Dr. Olden. Right.
Mr. Hoyer [continuing]. It will be.
Dr. Olden. Exactly.
Mr. Hoyer. We will be able to segregate, if you will, those
at risk and those not at risk?
Dr. Olden. Exactly. Take the beryllium workers. We now
know, in hindsight that 90 percent of the people who have
berylliosis also have the beryllium susceptibility gene. There
is a susceptibility gene that has been isolated and identified.
We now have identified the gene, for example, that protect us
against organophosphate pesticide toxicity. We have identified
at least one gene that we know protects, and there are people
who do not have that, and if we knew who those persons were.
That is an important one because we know that gene is not
expressed early on in children. So children and animals, like
rodents and mice both, are much more susceptible to
organophosphate pesticide toxicity because of the absence of
the expression of one gene. Now, it is later expressed in
children, but it is turned on much later.
Mr. Hoyer. Conceptually, 25 years from now, or it may be
even sooner, at birth, we would get a book all about ourselves.
This is what you need to watch out for?
Dr. Olden. Well, I think Dr. Kirschstein and others would
say here, clearly, medicine is going to become more predictive
and preventive, rather than diagnostic and treatment. And
probably what we are going to do is a stage where we get some
sort of bar code at birth, like one that you use when you go
through a check-out counter at a grocery store. A physician
could just print it out and find out what your susceptibilities
are, and they all are not going to be just environmental. There
are other susceptibilities like breast cancer 1 and 2 genes.
There are different kinds.
Mr. Hoyer. But it is not only your physician, but your
parents.
Dr. Olden. Yes.
Mr. Hoyer. To guard against exposure to things that you are
uniquely susceptible to; IA, IE and the asthmatic.
Dr. Olden. Yes. What we really need, Congressman, is a
comprehensive database that includes a lot of things. All of
the nine issues that I mentioned, if we had information on all
of those issues, then that is exactly what you need to set and
sell environmental health policy to protect the health of the
American public. And so that is what we need.
Mr. Hoyer. Dr. Kirschstein, do you want to make a comment?
Dr. Kirschstein. I wanted to make a comment, that as Dr.
Collins said yesterday, we need to be deeply concerned about
the privacy of that information in terms of discrimination, and
insurance and other aspects that might affect an individual's
life.
Dr. Olden. Right. Absolutely.
Mr. Hoyer. I think the more we can predict the future, the
more complicated it becomes in trying to make decisions about
what our predictions say. I think that we may ask questions we
do not want to know the answers to.
Mr. Porter. Thank you, Mr. Hoyer.
Mr. Jackson?
COLLABORATIONS WITH NCI
Mr. Jackson. Thank you, Mr. Chairman.
Thank you, Dr. Olden, for appearing before our committee
today.
Dr. Olden. Thank you.
Mr. Jackson. I am pretty sure you are familiar with the
line of inquiry that I have been raising amongst NIH directors
over the last couple of hearings.
Dr. Olden. Yes. Yes, I am.
Mr. Jackson. Since you are so familiar, I think I am going
to approach yours just a little bit differently then.
[Laughter.]
As the head of the National Institute for Environmental
Health Sciences, my understanding is that you are charged with
Environmental Health Science is primarily devoted to disease
prevention through understanding and minimizing adverse
environmental effects on human health and that you are the
Nation's premier research organization at NIH. The NIEHS has
been a leader in the area of understanding how poverty,
environmental pollution and health interrelate. The NIEHS has
developed a number of projects and grants programs designed to
define health disparities issue and to arm policy makers with
necessary information to reduce these disparities.
So I was just wondering since prostate cancer, for example,
is very high amongst African-American men and breast cancer is
reportedly twice as more lethal amongst African-American women
than any other ethnic group or even the majority population,
and that incidences, for example, of cancer in our community
are higher, I am just wondering does your Institute, at least
it is my understanding that Institutes are supposed to better
coordinate across the entire NIH, that that is the purpose of
being an Institute, has your Institute worked out any kind of
grant proposals, RFPs, RFAs with Dr. Klausner that you would
like to share with the committee?
Dr. Olden. Yes, we have. We collaborate with the National
Cancer Institute on many projects, including breast cancer and
prostate cancer, not only with prostate cancer and not only
with NCI, but with the National Institute on Aging as well. We
co-fund a program with NCI--as a matter of fact the bulk of the
support is NCI dollars--called the Agricultural Health Study.
The purpose is to look at exposures to pesticides and breast
cancer, but also many other cancers, as well as diseases like
Alzheimer's and Parkinson's. And many of the pesticides have
estrogenic activity, and most of the exposures, 90 percent of
farm-workers in the United States are minorities--mostly,
today, Latinos, not African Americans, but African Americans
certainly, as a population, are second in terms of being
agricultural workers.
This study has been conducted in Iowa and in North Carolina
to bring in the African-American population. In addition to
that, we created a specialized Environmental Health Center. We
have three of them that deal solely with agricultural
chemicals, and two of those are in California. So we have a
number of projects that we are working with NCI on. We also
fund the Long Island Breast Cancer project with NCI.
So the answer is, yes, we share a lot of information with
NCI and work very closely together on both breast and prostate
cancer, and certainly estrogens are also thought to play a very
important role in prostate cancer.
FINDING MINORITY BIOMEDICAL RESEARCHERS
Mr. Jackson. Dr. Olden, the Chronicle of Higher Education
wrote an article on November 10th of 1993 that said that the
National Cancer Institute was having a problem finding minority
researchers. Do you share that opinion?
Dr. Olden. Finding minority researchers? Yes, I do. I have
problems finding minority biomedical researchers. I used to be
director of a cancer center at Howard University, as you
probably know, and when I was there, I had a problem finding
minority biomedical researchers. The truth is there is a
pipeline problem, and we are doing something to address the
pipeline problem.
Mr. Jackson. You will have to forgive me. You have taken me
aback a little bit here. You had a problem finding minority
researchers at Howard?
Dr. Olden. Yes.
Mr. Jackson. Really. Could you care to explain where at
Howard you were looking for them?
Dr. Olden. Well, I think I used every possible mechanism. I
was director of an NCI-funded cancer center, and the
requirement of maintaining an NCI-funded cancer program is that
you have to recruit investigators who are nationally
competitive in terms of being able to secure independent
research dollars. And if you do not do that, you do not exist.
So we had a problem of finding people who had that kind of
experience, and it is a pipeline issue. If only 600 or so have
graduated in ``X'' numbers of years, there is no way that many
of them are going to have the kind of experiences that are
necessary to compete for a grant with the National Cancer
Institute or the National Heart, Lung and Blood Institute or
even my Institute.
So, yes, I did have the problem there, and I still have it
at NIEHS. I have a position open now, and I would be very happy
to have a minority candidate for the position. The position is
my scientific director.
OUTREACH EFFORTS
Mr. Jackson. It is kind of hard for me to, well, and maybe
it is me. I went to North Carolina A&T, and it is really hard
for me to imagine that Howard University, with all of the
funding that this committee and this Congress gives to the
university, has a problem creating a pipeline of minority
researchers for an organization that is like right around the
corner from----
Dr. Olden. Well, Howard is certainly----
Mr. Jackson. Stay with me for a second, Dr. Olden. Stay
with me for just one second. Let me move from that question to
another one.
Then, if you could explain to me, since there is this
dearth of finding minority researchers, maybe you can help me
understand whether or not you share the view that--well, let me
rephrase that.
Maybe you can help me understand what is your assessment,
generally, of the outreach efforts by the NIH to try and find
minority researchers? Sufficient? Could it be better?
Dr. Olden. Well, I think there is no program, no activity,
I have never seen anything, Mr. Jackson, that could not be
improved, and I think NIH is very concerned about improving its
outreach activities to minorities and underserved populations.
But can it be improved? Everything in my Institute can be
improved, and I suspect that effort in the NIH could also be.
Mr. Jackson. Well, towards that very generous spirit, what
recommendations for your own Institute are you moving towards
to improve it?
Dr. Olden. Well, for one thing, I am supporting a number of
programs. I am supporting a Meyerhoff Program at the University
of Maryland Baltimore Campus. It was created and developed by
an African American, who is the president of the university.
Mr. Jackson. I am sorry. Did you say Baltimore, Maryland?
Dr. Olden. Yes.
Mr. Jackson. But not like, let us say, Howard University,
where there would be a natural pool of----
Dr. Olden. I am sorry. All of the students in this, I think
close to all of the students are African Americans, and this
program is recognized as the best program in the Nation at
producing minorities who go on to become biomedical
researchers. And so I have invested in that. As a matter of
fact, we contribute $600,000 per year, and we are now in the
seventh year, I believe. And, in fact, it was co-funded, at the
outset, by the Office of Research on Minority Health.
We are making investments other places, as well. I do not
know if you know about our ARCH program, which is also a
program that we developed, which is a partnership between
research-intensive universities and HBCUs, and we are
reannouncing that to include other minority-serving
institutions.
So we have programs, a number of them, in fact.
Mr. Jackson. Let me just ask one last question, and let me
also thank you very much, Dr. Olden, for your candor.
Are you aware of the persons who are in charge of the
better coordination of addressing these disparities across NIH?
Dr. Olden. You mean the trans-NIH working group?
Mr. Jackson. There is a committee that Dr. Kirschstein has
been----
Dr. Olden. Yes. Yes, Dr. Tony Fauci and Dr. Kirschstein's
deputy director. Yes, I am aware.
Mr. Jackson. Thank you very much, Dr. Olden.
Thank you, Mr. Chairman.
Mr. Porter. Thank you, Mr. Jackson.
Ms. Lowey?
BREAST CANCER
Mrs. Lowey. Thank you very much, and I do want to
apologize, Mr. Chairman, and our distinguished panel for being
late and missing most of the testimony. As you know, we are
pulled in so many directions. But I have such great respect for
the important work you are doing, and I look forward to
continuing to work with you, Dr. Olden.
I know there has been some discussion, and you addressed
the funding of the Long Island Breast Cancer Study.
Dr. Olden. Yes.
Mrs. Lowey. As you know, I have been working with Fran
Visco and the National Breast Cancer Coalition for many years
towards our shared goal of truly understanding breast cancer.
Dr. Olden. Yes.
Mrs. Lowey. While many believe that a link between our
environment, drinking water, soil, and air quality, pesticides
and the incidence of breast cancer in our community can be
readily identified, there has not been very specific research
on these factors. In fact, every year when we bring up the
issue, we really do not get conclusive evidence, and it is
either because the research has shown there is no conclusive
evidence--as Dr. Kirschstein is shaking her head--or perhaps we
have not done sufficient work in this area and maybe some of
each.
There are, to the best of my knowledge, a limited number of
studies, and in many cases these studies have raised, rather
than settled, important questions. And I really do feel that we
have got to get some more information. So I have introduced a
bill to create Centers of Excellence, very much like the
Centers on Children's Health within NIEHS, because I believe
that this kind of focused research would complement programs at
the National Cancer Institute, at the Department of Defense and
at academic medical centers around the country.
What this bill would do is establish cooperative
relationships between institutions so that researchers working
on Long Island would share their findings with colleagues in
New York City, Westchester, Connecticut, Northern New Jersey,
as well as with other areas around the country.
Perhaps most importantly, the proposal would also create a
role for breast cancer patients, their families and advocates
in giving their experiences to the scientists, which we hope
would shed light on the whole issue. I do feel that the
experience of women and families in their neighborhoods should
provide some important information for the investigation. And I
just feel this kind of joint effort could be very, very
critical.
Could you comment on this approach.
Dr. Olden. Well, we would be very pleased to work with the
National Cancer Institute, and I guess if you brought this up
with Dr. Klausner, he also indicated that he would be very
pleased to work with us on this issue. We worked very well with
NCI on a number of issues, and this would be one that I think,
again, that we would be very pleased to get advisers to look at
and develop an appropriate research agenda to address your
concerns.
Mrs. Lowey. I appreciate that, and I hope, as the bill
moves along and the process moves along, that we can continue
our dialogue because I certainly have a great respect for the
important work you are doing.
Dr. Olden. Yes.
Mrs. Lowey. Thank you.
Dr. Olden. We think that is very important work.
Mrs. Lowey. Thank you.
And thank you, Mr. Chairman.
MIXTURES
Mr. Porter. Thank you, Ms. Lowey.
Dr. Olden, getting back to the cDNA microarrays.
Dr. Olden. Yes.
Mr. Porter. In many cases, a worker, for example, is
exposed not just to one chemical substance, but a number of
them at the same time, let us say hydrochloric acid and
ammonia. Will this kind of technology assay two at the same
time or three or four?
Dr. Olden. Yes. That was why we got excited about it day
one, Congressman Porter. It is one of the nine areas that I
identified last year that has been crucial for environmental
health decision making. An area where we had very little
information is on mixtures. Almost all of our studies over the
years in environmental health research and in toxicology have
focused on one chemical or physical or biological agent at a
time, and that is not consistent with the real world. We live
in a world where we are going to be exposed to thousands of
things during the course of this day. So it is the mixtures.
But we did not have the tools to answer the question. That is
one thing that the cDNA microarray approach, we believe, will
allow us to do.
Mr. Porter. If you look at all of the environmental factors
that might affect health, and you begin with synthetic
chemicals, and you said, well, we do not have to look at all
85,000, we can look at just 10,000.
Dr. Olden. Right.
Mr. Porter. And then you add to that the byproducts of
combustion and industrial processes, you look at foods and
nutrients, natural substances, and we talked to Dr. Straus this
morning about an interaction between a natural substance and a
drug if you took them at the same time, prescription drugs,
other pollutants.
How, with so many possible environmental factors, can you
again prioritize or separate out which ones to look at, and are
you looking at real-life situations where you might be exposed
to certain ones and saying, ``Those are the ones that we better
look at''?
Dr. Olden. That is exactly right. That would certainly be
at the top of our list of priorities. We look at the real-world
exposures. I think you can get a panel of 20 people in a room,
and we can pretty much agree on the top 20 or 40 or 100 most
common pollutants to which you and I are exposed to as
mixtures. Automobile exhaust is clearly one. Second-hand smoke
is clearly one. So we can identify them. So I think you can
generate a list of priorities, maybe not narrow it down to ten,
but you do not want to do that. But I think you could get a
consensus on what the top----
Mr. Porter. And will this technology allow you then to
study a group of them?
Dr. Olden. It will, yes. That is what we expect.
Mr. Porter. That is very impressive technology.
Dr. Olden. Right now we are not trying it with mixtures,
but that is the objective because we had no technology for
looking at mixtures. And the technology that we do have is
simply too expensive to take into account all of the different
possible combinations that you just referred to.
If it is going to cost you $2,000,000 to $6,000,000, and
you are only testing ten chemicals a year anyway, you cannot
test all of the different permutations of chemical, physical,
and biological agents. It is not just chemicals. Biological
agents also interact with chemicals and vice versa. So it is
complex, unless you have the right tools.
HERBAL MEDICINES
Mr. Porter. Well, we were, as I say, talking to Dr. Straus
this morning about his mission, and he was talking about all of
the substances that are on the market already and more going on
every day. But if you think of your job, it is even much more
complex than his is.
Dr. Olden. Well, we are collaborating with Dr. Straus
because you remember I believe last year I mentioned our
interest in testing herbal products.
Mr. Porter. That is my next question.
Dr. Olden. All right.
Mr. Porter. You can go ahead and answer it. What progress
have you made there?
Dr. Olden. Well, we have not done any chronic tests yet,
but we have done some pre-chronics on four. We do plan to start
probably as many as two this fiscal year 2000. So it is
important, and that is why we are interested. It is not only
whether this mixture, which they are, is toxic in itself, but
it could interact with pharmaceuticals, which people are also
taking.
So it is a difficult and complex issue that certainly will
require the best of all of the Institutes in the National
Institutes of Health to answer. And so we are very interested
in collaborating with Dr. Straus to help us, in terms of
expertise and advice as to what we need to do.
PARKINSON'S DISEASE
Mr. Porter. There are some studies that suggest that over
90 percent of late-onset Parkinson's disease may be due to
environmental factors. Can you tell us what you are doing in
that area.
Dr. Olden. Yes. We are collaborating. As a matter of fact,
the National Institute for Neurological Diseases and Stroke is
the leader in the NIH, and they brought together three other
Institutes--Aging, and Mental Health and my Institute--together
in partnership, and we have identified a research agenda to
address Parkinson's. There is both a genetic and environmental
component. So we put in place an agenda to address those
issues.
NIEHS is looking at four things. We are looking at
industrial chemicals, agricultural chemicals, which all have
been reported to be risk factors, exposures to industrial
metals--that is, occupational exposure--and finally we are
supporting research on the basic biology of exposures to these
agents. There is evidence that the whole biological cascade has
something to do with protein degradation. And so we are
supporting research at the Parkinson's Foundation to look at
how the proteins that are involved in Parkinson's, they are
also involved somehow in the protein degradation cascade. And
so those are the four.
Another area we are looking at is susceptibility. A number
of our investigators are looking at the genetic bases of
susceptibility, focusing on various enzymes that are involved
in the metabolism of environmental genome biotics.
Mr. Porter. Thank you, Dr. Olden.
Mr. Jackson?
HEALTH DISPARITIES
Mr. Jackson. Mr. Chairman, I have no further questions at
this time. Thank you, sir.
Mr. Porter. Ms. Lowey?
Dr. Olden. May I just respond on one thing to Congressman
Jackson?
Mr. Jackson. I would be happy to engage.
Dr. Olden. When you asked me did I know Dr. Yvonne Maddox
and Dr. Tony Fauci, not only do I know them, I am working with
them on the committee along with all of the Institute
directors. They chair the committee, but Dr. Kirschstein asked
all of the Institute directors to be active and involved, and I
am interested in this issue and have been my whole life,
obviously. When I came on in 1991 as director of the Institute,
I immediately put in place a program to address environmental
justice, which is our piece of health disparities, and I did so
because of having served as director of a cancer center in
Washington, D.C., I was well aware of the fact that many of the
cancers are probably related to the environment, and people do
not control where they live and work. They are there because of
their educational level and poverty.
And so I was very sensitive to issues related to poverty,
race and ethnicity, and we developed a research program that I
am proud of, that responds to these issues.
Mr. Jackson. Let me say, Dr. Olden, I appreciate hearing
that from you. But at least appreciate it from my perspective
that oftentimes it is not so obvious. And when I look across
the money that this committee is asked to appropriate for
various Institutes, Centers and offices at the NIH, it is very
clear that the absence of minority researchers who are not
performing substandard research are absent, and I am trying to
get to the bottom of that and find out what we can do to
increase the likelihood that those who are interested in
research might, indeed, be able or willing and have the
opportunity to do that research with the NIH.
And so I appreciate your interest and obviously your
commitment. I thought very interesting that most of your resume
has Howard University accolades associated with it, various
fellows and various types of honors that the Howard University
had bestowed upon you. But while at Howard University, you sat
before this committee a few minutes ago and said that you were
at Howard, in the middle of Howard Medical School, and could
not find part of the answer to the pipeline problem. You looked
outside of Howard.
And then when I asked you now, as the director of the
Institute for Environmental Health Sciences, what are you doing
about it, and you said, well, you did not see it at Howard
University's campus, you saw it somewhere out in Maryland,
which I, you know, respect. I just think that oftentimes when
we say we are trying to address some of the pipeline issues, we
may not necessarily be looking in the right place. And I am
sure if Dr. Louis Sullivan were here today, he would say that
he has a sufficient amount of pipeline students at Morehouse.
Dr. Olden. And we are supporting two programs at Morehouse
to deal with the pipeline problem. I think we are supporting
about $300,000 worth of pipeline problem issues at Morehouse.
So we are going a number of places, Mr. Jackson. Morehouse
is one of them.
Mr. Jackson. I appreciate that, Dr. Olden.
Thank you, Mr. Chairman.
EDUCATION OF PHYSICIANS
Mr. Porter. Dr. Olden, I am going to ask you a question
about DES and the need for education of physicians and
patients. But I would like you to answer it in a broader
context about any other similar types of problems.
NIH estimates that almost 5 million women took DES, which
is diethylstilbestrol, between 1938 and 1971. Apparently, this
was a drug to prevent premature labor. Preliminary results from
a national research and education program that was started in
1992 points to potential health problems throughout life for
those exposed to DES, not just as adolescents and young adults
as once thought. Also, new findings from animal research
suggest that DES may affect the granddaughters of the original
DES mothers, as well. These findings highlight the need to
educate the medical community that women who were exposed to
DES and their families need to be watched more closely.
What are you doing to educate physicians and patients about
these findings and what are you doing to educate the physician
community about the findings that your Institute makes in
regards to other toxic materials and substances?
Dr. Olden. Thank you. The studies you cite about the
granddaughters were done at NIEHS by an investigator named Dr.
Retha Newbold. And that is a very interesting study because we
thought that it was only the first generation of women who were
exposed in utero that would be at increased risk for certain
cancers. But clearly, her studies with animal models suggest
that the granddaughters may also be at increased risk for
cancers.
We started a number of years ago--in fact my predecessor
started--an environmental and occupational health training
program for physicians. What we tried to do through that
program is to get incorporated into the training of physicians,
while they are in medical school, information about
occupational and environmental medicine. That program is still
ongoing.
So it is okay, but it is not adequate, probably. When we
started the program, I think the estimate was that physicians
were getting roughly four hours of occupational and
environmental medicine training. The last time we did a review
of our program, it had increased some and it was something like
six hours rather than four hours. That is not enough.
So the other thing that we are considering is to have
continuing medical education for physicians who are in
practice, to bring these issues. And certainly we have been
talking with the Association for Physicians for the
Environment, to see if we could develop that kind of activity.
But there are so many physicians who were already in the
practice of medicine--were out of medical school by the time we
initiated our training--and so they clearly did not get much
training in occupational or environmental medicine, unless they
chose that as a specialty.
So we have training programs in medical schools, but we
probably need to do more. In other words, develop continuing
medical education training courses.
OCEANS AND HUMAN HEALTH
Mr. Porter. Dr. Olden, thank you. Finally, are you doing
any research in the area of oceans and their relations to human
health?
Dr. Olden. Yes, we are. We have been very interested for
years in the interrelationship between human health and the
health of other plant and animal species. One of the first
indicators that there are pollutants in the environment that
may represent a threat to human health is often obvious in
marine and freshwater environments.
So we have been supporting research for a number of years.
As a matter of fact, we have five marine and freshwater
biomedical research centers. The main purpose of these centers
is to develop alternative models. Many of the marine species
make excellent models for toxicity testing and evaluation. So
that is one objective.
But the other one is also to use them as sentinel species,
as biomarkers for changes in the environment. For example, the
pfisteria outbreak that happened in this region about two or
three summers ago in Congressman Hoyer's district, I believe,
in Maryland along the Eastern Shore, and also in North
Carolina.
So we supported most of the research that has been used to
prevent further outbreaks in subsequent years. And now we have
a major project at the University of Maryland in Baltimore, in
fact, to clone the genome of pfisteria because the problem was
that we did not recognize when the numbers were increasing,
because pfisteria has 24 different disguises and it is only one
that we recognize, and that is the one that is harmful. It
would be helpful if we had a DNA fingerprint to identify that
microorganism.
So now we are generating that through a grant at the
University of Maryland. It is a partnership between Johns
Hopkins and Maryland.
Mr. Porter. Dr. Olden, thank you for the outstanding job
that you are doing at NIEHS. It has been a real education and a
real pleasure to have you up here before this subcommittee. I
have luckily been here the entire time that you have been at
NIEHS and have been able to hear you each year.
We can tell the enthusiasm that you bring to your work. It
is very evident the knowledge that you bring to your work. We
are very thankful that you are in that position and doing so
well for NIEHS.
Dr. Olden. Thank you very much and I have enjoyed appearing
before this committee.
Mr. Porter. Thank you for appearing.
We will stand briefly in recess.
[The following quesitons were submitted to be answered for
the record:]
Tuesday, February 29, 2000.
NATIONAL INSTITUTE OF NEUROLOGICAL DISORDERS AND STROKE
WITNESSES
GERALD D. FISCHBACH, M.D., DIRECTOR
AUDREY S. PENN, M.D., DEPUTY DIRECTOR
KEVIN E. KIRBY, EXECUTIVE OFFICER
ANDREW C. BALDUS, BUDGET OFFICER
DR. RUTH L. KIRSCHSTEIN, ACTING DIRECTOR
national institute of neurological disorders and stroke
Mr. Porter. The subcommittee will come to order.
We continue our hearings on the budget for the National
Institutes of Health with the National Institute of
Neurological Disorders and Stroke. We are very pleased to
welcome Dr. Gerald D. Fischbach, the Director.
Dr. Fischbach, it is wonderful to see you. We hear so many
good things about the job you are doing within NIH. We are
anxious to have you tell us what your Institute is doing; and,
in that process, I would ask you to give us some understanding
from your perspective as to how we can show that the increases
at NIH are being well spent, are justified, and are being spent
for good science.
Dr. Fischbach. I will try. Thank you, Mr. Porter.
I would like, before beginning, to introduce Dr. Audrey
Penn on my left, the deputy director of NINDS; Mr. Andy Baldus,
our financial officer; and Mr. Kevin Kirby, who is the
executive officer of the institute. Ruth has already been
introduced.
I just want to add that for years before I came to the NIH
I thought of Ruth as the soul of the NIH in many ways, and she
is demonstrating now that the brain and the soul are actually
more connected than many people might think. It is a pleasure
to have her here.
I will try to pay attention to the issue that you raised.
I am pleased to present the President's 2001 budget which
for NINDS amounts to $1,085,000,000, an increase of $55 million
over last year.
I became director of NINDS about 18 months ago with great
respect for the institution and enormous enthusiasm. My
enthusiasm has grown every week on this job because advances in
neuroscience have continued at an incredible pace with direct
impact more than ever on the burden of brain disorders. My
enthusiasm has grown because of the generous support of the
public, largely steered there by this committee and your own
efforts, Mr. Chairman; and I think the entire scientific
community is grateful for that. Although your term is coming to
an end, I do hope you will not be far from the biomedical
enterprise.
STRATEGIC PLANNING
My enthusiasm has also grown because we have a wonderful
staff in the institute, and many of them are here, who have
initiated a very productive and powerful and, in my view, a
very successful planning process.
I discussed last year the reorganization of our institute
into planning panels and clusters and announced our first
strategic plan, Neuroscience at the New Millennium, which
stated very clearly what our vision was, what our goals were,
and now I want to add to that, this supplement, which is the
implementation update as of this month. It is rather rewarding
to review that implementation program. We don't want to just
develop plans and leave them alone. We want to implement them.
The degree of progress, which I will mention a little bit, has
been remarkable.
We planned on a level of basic science, based on a need to
translate basic science into clinical, patient-oriented
research. We have taken into account the changing nature of
science, that it is moving towards more consortium
arrangements, new funding mechanisms, and we have responded to
a need to coordinate our efforts within the institute, between
NIH institutes--and I will mention some of the collaborations--
and between agencies within the government.
We have initiated programs with the VA on Parkinson's
disease and with the Department of Defense on
neurofibromatosis. We had a meeting yesterday with the National
Science Foundation for a growing program in neurocomputation
and with the FDA working on new problems in implantable devices
and in stem cells for neurological research. So I think the
planning process is well underway.
USE OF FUNDING INCREASE
Before describing our plans for fiscal year 2001, I would
like to review a little bit about how we spent our money in the
past year and why I think it has been wisely spent. We had a
large increase 2-years-in-a-row in our budget of about 15
percent. We have used that in several ways.
In the first instance, we increased the number of new
grants that we funded by a total of 202 in 1999, and in 2000 it
will level off a bit to an increase of 24. Our success rate has
increased from 28 to 35 percent. We have decreased the cut in
each grant, and the cost of each grant has gone up to about
$335,000 per grant. That sounds like a big number, but when you
subtact the indirect cost and subtract what an investigator
needs to pay in salary support, it leaves about $50,000 maybe
$70,000 for animal costs, supplies, and crucial small pieces of
equipment, barely enough to support a lab of three or four
people, let alone a lab of 10. So while the funds are
increasing, I feel that we are catching up from several years
of real shortfall.
My thought is that in these new grants we are funding
superb science. The evidence I can offer comes at different
levels. First, my own reading and I think the reading of
experts in the field, of the grant applications, is that they
are better now than they have ever been before and informed by
many new techniques. So the success rate increasing to 35
percent is justified certainly in the area of neuroscience.
You can see it in the quality of research publications at
both the basic science and the clinical levels. The number of
journals has increased, and the quality of the reporting is
actually breathtaking. You can see it in the growth of the
biotechnology industry. You can see it in the fact that we are
attracting the very best and the very brightest people in all
of undergraduate science to come into biomedical science and
into neuroscience in particular.
The Society of Neuroscience continues to grow from 500
people in the early '70s at its founding to over 28,000 today.
I think the U.S. now is the envy of the world in terms of its
biomedical science. Half of our research population and our
meeting participants are from abroad. Most of our trainees are
here from abroad. Hopefully, they will take what they have
learned through NIH funding back to their own countries.
I think in the long run we also see an improvement in
health care. If it was me--and I know this sounds like a bald
statement--I would rather have a stroke today than 5 years ago.
I would much rather have my diagnosis of multiple sclerosis, or
intractable epilepsy, or Parkinson's disease made today than 5
years ago mostly because of very recent advances in each one of
those fields.
I think we are seeing the payoff. You can't see it year by
year, but over the course of 5 or 10 years I think it is very
clear. I think we are spending our money well.
PARKINSON'S RESEARCH
In addition to the grants, the increase in our funding
allowed us to fund eight new Morris K. Udall Centers of
Excellence in Parkinson's disease research. We were initially
scheduled for four, but we funded eight. That brings us to a
total of 11. That group is meeting on March 3 in Atlanta to
plan together in a newly collaborative effort ranging from
basic science through new clinical trials. Eighty investigators
will assemble, and I think they represent a significant force
in the field of neurodegeneration, research which I will say a
bit more about in a moment.
We have had new initiatives in exploratory grants in
pediatric neurological disorders including Friedreich's ataxia,
Rett's syndrome, and a number of others. We have instituted a
very novel call for proposals and a remarkable new therapy
involving deep brain electrical stimulation which has proved so
effective in selected cases of Parkinson's disease and which
appears to have applicability in cases of intractable epilepsy
and in other disorders as well. Although it seems successful,
there is a tremendous amount to be learned about electrode
design, exact placement of the electrodes, and the limits of
use of this technology in conjunction with more traditional
medical therapies.
INFRASTRUCTURE SUPPLEMENT PROGRAM
We have instituted an infrastructure supplement program
which all of our advisors and our council suggested that we do.
We funded that at the level of $20 million last year where we
replaced desperately needed pieces of equipment, outmoded
microscopes and centrifuges, which are crucial for the entire
enterprise. We had 1,800 grantees, and we received 1,500
applications. I suspect that means everyone because people
doubled up on some of them.
PLANS FOR FY 2001
As for our plans for 2001 I want to emphasize four areas
before the questions.
First, we want to maintain our efforts in
neurodegeneration. We want to mount, as we say in our plan, an
attack on neurodegenerative disorders over the entire life
span, from birth to old age. The scope of neurodegeneration I
don't think is generally appreciated by the public. Certainly,
the classic neurodegenerative disorders of Alzheimer's disease,
Parkinson's disease, amyotrophic lateral sclerosis, and
Huntington's disease are included. The neurodegenerative
disorders of childhood, Friedreich's ataxia, cerebral palsy,
and many others are in that category. But neurodegeneration is
ubiquitous. The same processes occur, although they are not the
primary cause, in epilepsy and in multiple sclerosis. Even
disorders traditionally thought of as mental disorders like
depression and chronic stress are now clearly associated with
ongoing debilitating neurodegeneration.
I believe there are reasons for hope in this series of
intractable disorders, not the least of which is we understand
much better now than we did 2 or 3 years ago how cells die in
the nervous system. Regardless of the inciting cause, many of
them follow a single common pathway of enzyme activation and
self destruction. Cells dying in the spinal cord of patients
with ALS die in much the same way as cells die in substantia
nigra of patients with Parkinson's disease, or as they do in
the cerebellum of children with Friedreich's ataxia. We just
have to intervene in that process to make enormous gains.
Now, there is a crucial need for early diagnosis. I think
there is hope in this regard, too, from two fronts. One is the
genomics. The completion of the genome project is providing
tools for us to make diagnoses on blood samples. But also the
expanded use of modern, sophisticated imaging techniques should
allow us to detect neurodegeneration before it is clinically
evident.
MULTIPLE SCLEROSIS
I want to show you in three posters an example involving
multiple sclerosis--this is not a new finding, but this year
its wide applicability in following treatment and early
diagnosis has become manifest.
These are two MRI images. On the left is a normal MRI, and
on the right is one that has been enhanced by gadolinium, a
rare earth element. What is striking here is that gadolinium
crosses the blood brain barrier and stains--makes white--new
lesions which are either invisible or barely detectable by the
usual MRI image. This ability to detect very early lesions has
revolutionized therapy in multiple sclerosis.
The next slide shows that we do have an effective therapy
in this disorder. There are several interferons now, without
becoming proprietary about it, these interferons can reduce the
number of gadolinium-stained new lesions to a very, very low
level. That is a very dramatic curve, repeated now in many
different studies.
The payoff is in the next diagram where you can see the
course of typical multiple sclerosis, which is called a
relapsing and remitting disease. There are pulses of activity
when patients are severely debilitated followed by periods when
they seem to be in remission. It is now clear using the
gadolinium scan that even those patients in remission are
developing new lesions even when not symptomatic. Clinical
practice has changed so that people in remission are being
treated now with interferon with the clear result that severe
disability is postponed and reduced. I have used this as an
example of the need for early markers before the disease has
worked its damage so that early intervention can minimize the
effects of neurodegeneration.
PARKINSON'S DISEASE
Parkinson's disease remains--still on the topic of
neurodegeneration--one of our top priorities, and we have
completed a report requested by Congress on a 5 year strategic
plan for Parkinson's disease which is due March 1. I would be
glad to answer as many questions about that as possible. The
planning process involved extramural and intramural scientists
and virtually every advocacy group in the Parkinson's
community. I think we are all gratified with the process.
In addition to degeneration, we want to emphasize
regeneration and repair of the nervous systems. Our programs in
prosthetic devices have developed exciting new ways of
stimulating the nervous system to produce hand grasp in spinal
order injured patients. There are, as I am sure you know,
extremely promising results in animal studies of stem cell
biology which offer promise in many areas of regeneration and
repair.
HEALTH DISPARITIES
One of our areas of emphasis has been for some time the
issue of health disparities. This is a huge problem, and I
think Ruth and others have recognized it. It requires the
coordinated effort of the entire NIH, but NINDS has a long
history in this area. We are proud of a new Office for
Specialized Programs in Neuroscience, established in November
of 1998 that is headed by a very talented program director, Dr.
Al Gordon, to focus on increasing the number of scientists at
predominantly minority institutions. The budget for this
program, with the help of John Ruffin, has grown from $6
million in 1998 to $23 million this year; and we project an
increase under the President's FY 2001 budget of up to $26
million. If possible during the question and answer period I
would like to discuss these programs and other areas of
outreach.
NATIONAL NEUROSCIENCE RESEARCH CENTER
I would like to end by talking about an effort now under
way at the NIH to create a National Neuroscience Research
Center. This is stimulated by the realization of several of us,
especially Dr. Steve Hyman of Mental Health and myself, that
neuroscience has advanced to the point where these fields are
coming together. The difference between traditional neurology
and psychiatry is disappearing. The basic science underlying
disorders of mood and movement is exactly the same, and studies
of motivation and addiction are converging in the same
direction.
We feel that the field would be served by bringing
scientists together across Institute boundaries and across the
disciplines of clinical research and basic science research
into one facility to focus on translational and patient-
oriented research. It is an extraordinary time in the history
of the NIH. We are discussing this with several Institutes
interested in contributing to the Center.
I remember we discussed this at the very first meeting I
had with you when I first arrived on the scene. You wondered
whether the excellence of the intramural program could be
restored to its tremendously significant history of the early
'70s, late '60s, when it seeded programs throughout the
country, certainly in the area of neuroscience. I am convinced
that it can. I think the excellence can be raised. I think we
can put the brain back together and in the process save
enormous amounts of dollars in the intramural programs. This
comes along with the hope for a new physical structure to jump
start all of the reorganizational efforts.
I am optimistic about the intramural program in setting an
example, being a role model for programs throughout the
country, actually. There should be much closer interaction
between neurology, psychiatry and the basic neurobiology
departments in the extramural community. I am optimistic that
the field of neuroscience will move in a much more coordinated
way. I would be glad to answer any questions about any of that.
Mr. Porter. Thank you, Dr. Fischbach.
[The written statement of Dr. Fischbach follows:]
FROM DISCOVERY TO PRACTICE
Mr. Porter. Earlier you had alluded to the movement of
discovery into practice. I think you said that today, for
multiple sclerosis, a new imaging technique is being used. Can
you give us an overview of what you see in general regarding
the movement of discovery and bringing it into practice and how
we educate practitioners to use new techniques and new
approaches that you--that have been discovered through NIH?
Dr. Fischbach. The education question is a very interesting
one. The movement of discovery into practice I really do
believe is a critical issue. It is much harder than we first
imagined. We have developed new grant mechanisms by which
individuals can travel between labs and collaborate with each
other on a much more intimate basis than ever before. People
working on spinal cord circuits can interact with those
interested in rehabilitation and repair so that they can
develop rehabilitation strategies based on what we know of the
circuits. You can repeat that in every area.
In Parkinson's disease, the need for stimulating the brain
is based on years of experimental work in subhuman primates to
understand the basic circuitry in the basal ganglia. The need
now is to get the circuit and cellular neural science together
with neurosurgeons in the operating room who can think more
clearly about the unique features of human circuits. I think I
can repeat that in virtually every disease that we study.
In every step of the way there is a need to educate
physicians. We have a remarkable success story in the area of
stroke therapy. Tissue plasminogen activator, injected
intravenously within 3 hours of the first signs of a stroke,
can reverse the symptoms of an ischemic stroke. There is a
small subpopulation of hemorrhagic strokes in which that
doesn't occur. In fact, the TPA is a real threat and a danger.
So physicians must be educated to recognize those symptoms, and
we have a large public education effort under way to try and do
that.
Mr. Porter. There are, I think, something like 145 medical
specialty societies. Is there a direct program between NIH and
its various Institutes with going to those medical societies
and educating their members? What do we do in a formal way--
because that seems to me where they meet and have their ongoing
education programs as often through these societies, and it
seems to me that would be a way to get discovery more quickly
into their minds.
Dr. Kirschstein. Yes. Most of those medical specialties
have special societies and special conferences. Our staffs
attend all of the meetings. They have exhibits with the newest
findings. They talk to them about the newest activities, and
they participate in the continuing medical education aspects of
the speciality. Most medical specialties require that their
physicians take continual medical education and pass their
boards on repeated occasions now so they keep up with the new
things that are going on.
Dr. Fischbach. Going on, Audrey and I have spent a lot of
time with the American Academy of Neurology and the American
Neurosurgical Association to attempt to inspire them to move
beyond the traditional notions of how they practice their
medicine to reach out and adopt these techniques. I think that
is a major issue.
REPLACEMENT OF LAB EQUIPMENT
Mr. Porter. You said something about replacement of lab
equipment, and I am not sure whether you meant that
intramurally or extramurally. If you meant it extramurally, why
wouldn't that be done by the Center for Research Resources at
NIH?
Dr. Fischbach. The NCRR has been wonderful in sponsoring
programs for large pieces of equipment, $250,000 on up to a
million dollars, very vital for new technologies. But our
infrastructure program last year focused more on everyday
pieces of equipment. People who had 10- and 15-year-old
microscopes or outdated rotors for centrifuges could apply for
one-time-only supplements to their grants. It has been hard in
past budgets, given the numbers that I gave you with $70,000
left for supplies, to apply for and receive equipment on our
R01 grants. I think more often than not the equipment was cut
from grants, and now more often than not the parent
institutions have not been able to provide the funds. So this
is a more grassroots infrastructure.
Mr. Porter. Is this done in every institute?
Dr. Fischbach. I think it is a growing interest, but I
don't think so.
Dr. Kirschstein. Over the years I think many institutes
have done this. In the days when I was the director of the
National Institute of General Medical Sciences we did a good
deal of that for just the types of instruments that Dr.
Fischbach has mentioned. I think different institutes feel that
the needs of their particular grantees are different. There is
not an across-the-board program. It really should be
individualized to the needs of particular types of grant
applications and grants that are made.
BRAIN CELL REPLACEMENT
Mr. Porter. This is a question designed to simply let me
understand what you were telling us earlier. I think we know
that, for example, brain cells are continually growing. It used
to be thought that from the time of birth we had a finite
number brain cells, and now we believe that we actually grow
new ones. Am I correct so far?
Dr. Fischbach. So far.
Mr. Porter. Basic knowledge. You talked about cell death in
enzymes and interventions. Is this part of the same process--in
other words, presumably, if we can prevent cell death, then we
have done something that obviates any problem with cell growth
or cell regeneration. Are we talking about the same thing?
Dr. Fischbach. We are. It is like an equilibrium. The
number of cells you have is a balance between the number you
are producing and the number that you are losing. Simple
kinetics.
The notion of cells replenishing the store in the adult
brain is a brand new concept. There is some evidence for it. It
has been known for some years in rodents and subhuman primates
that one region of the brain, a very critical region for memory
called the hippocampus, had a population of cells that could be
replaced, as does the olfactory system. Cells in the epithelium
of the nose and in the first relay of the brain seem to be
replaced on a scale of every 120 days; about half of the cells
are replaced. But it was not thought and it is still very
controversial whether the cells are replaced anywhere else in
the huge universe of the brain. It is hoped that that is true.
There is some evidence that there are stem cells in the
adult brain, very rare though. So I don't think that the battle
in our lifetime is going to be won by promoting the formation
of new nerve cells. I think the battle is going to be won by
preventing the degeneration of the ones that we have. But it is
true that there is an increasing interest in the production of
new nerve cells in our adult human brain.
Mr. Porter. That is exactly what I wanted to know. Thank
you, Dr. Fischbach.
Ms. Pelosi.
ALZHEIMER'S RESEARCH
Ms. Pelosi. Thank you, Mr. Chairman.
Thank you all for your testimony and your excellent work.
Dr. Fischbach, I was struck by your testimony and
accompanying material that there really wasn't a great deal
said about Alzheimer's. Is that the Institute of Aging or is
that yours, too?
Dr. Fischbach. No, that is ours, too. We have a large
program in Alzheimer's disease basic research. This is an area
of interesting and I think very productive overlap and
increasing cooperation with aging. It does happen that
Alzheimer's disease increases in prevalence with aging. But
Alzheimer's is not directly caused by aging. In fact,
Alzheimer's disease can begin quite early in life, in the 40s
and 50s. So we have a very large commitment in grants. Indeed,
there are many scientists who feel there is a spectrum between
Alzheimer's disease at the one end and Parkinson's disease at
the other--Parkinson's alone, Parkinson's with dementia,
Alzheimer's disease with certain movement disorders,
Alzheimer's disease and memory loss in isolation. So we are
interested in the whole spectrum.
Ms. Pelosi. I thought maybe there was not as much reason to
be helpful in the Alzheimer's investigations because you didn't
mention it that much in your testimony.
Dr. Fischbach. The reason we have been focused a lot on
Parkinson's disease is that starts in a locus of the brain that
we know a lot about and there are promising medical and
surgical therapies. Alzheimer's disease is more global. I don't
mean to sound less hopeful, but if I were pushed I would say
prospects for advances in Parkinson's disease are more
immediate.
Ms. Pelosi. I have no complaint of what you are doing in
Parkinson's, and I commend you for it. Of course, all of us who
served with Mo Udall saw firsthand the impact of it.
As far as Alzheimer's is concerned, we have had people
testify who were 45 years old, breadwinners of their family,
children going to college, and now afflicted with Alzheimer's
disease in their middle 40s in a crucial time of life for
themselves, but especially for their families. I appreciate
what you are saying, it not being so directly associated with
aging.
Let me start at another place. When we had the Wise Persons
Panel any number of times here in the Decade of the Brain, we
were told over and over again that the greatest area for
scientific opportunity was the area of the brain, is that not
correct, Mr. Chairman? And I was hoping that would also apply
to Alzheimer's, seeing as how it affects so many families in
America. I was on the plane last night coming here, and a young
man was coming back from a conference from a pharmaceutical
company and said that they were on the brink of finding a cure
for Alzheimer's, which I found to be quite interesting. I
assume that you don't know anything about any hopeful
opportunities?
Dr. Fischbach. I do. I believe that there have been a lot
of advances in understanding how a dreaded protein, beta
amyloid, is produced and how it accumulates in the brain. In
the last year a long-sought mythical enzyme that destroys this
protein, which forms clots in the brains of Alzheimer's
patients, has been discovered and purified. A lot of that was
done in private industry based on NIH-funded research. There is
hope now that that enzyme has been identified to develop
inhibitors and prevent the deposition of amyloid. So I think
there are reasons for hope. Five or 10 years ago Alzheimer's
disease was unthinkable as a therapeutic target. Now there is a
lot of hope.
Ms. Pelosi. Do we have sufficient resources as far as grant
applications in this area?
Dr. Fischbach. There are a lot of opportunities. There are
Alzheimer's disease research centers. The area of Alzheimer's
research is well funded. It could always use more. I want to
reiterate that I think some of the very best science in
neuroscience now is being driven by the disorders much more
than in the past. People are entering the field of protein
chemistry because of an interest, the passion that was
mentioned earlier and interest in Alzheimer's disease.
STROKE IN MINORITIES
Ms. Pelosi. When we talk about stroke, again we could have
this question of almost every institute administrator who comes
before us. Obviously, there is a high incidence in the minority
community, for a wide variety of reasons. Could you talk a
little bit about that to the committee?
Dr. Fischbach. Stroke is----
Ms. Pelosi. I am glad to hear that you would rather have
one now than 5 years ago. Hopefully, no one has to have any,
but this disparity has been of concern to the committee for a
long time.
Dr. Fischbach. The disparity is enormous. It is probably
the most glaring and one that we must understand in the next
few years. My numbers show that, even in the stroke belt and
the buckle of the belt, the disparity between minorities and
whites is probably between two- and fourfold. If I have the
opportunity I will talk about our specialized neuroscience
programs in that area at Morehouse College.
Ms. Pelosi. That stimulated my questions, actually, as to
the work of Morehouse College.
Dr. Fischbach. Several years ago I initiated a program for
building research capacity at Morehouse College, whereby we
established a cooperative agreement to help that school build
in the area of neuroscience, recruit faculty, write NIH grants
and grow in size and influence the entire medical school. Based
on the success of that program, we issued an RFA and are doing
it at five other predominantly minority schools around the
country.
The interesting thing at Morehouse is we are beginning to
move beyond building capacity to addressing this issue of
stroke. And in collaboration with the Heart, Lung and Blood
Institute, which also has a program at Morehouse, we developed
a challenge to Morehouse to develop programs dealing with
stroke in the population, prevention, novel methods of
treatment involving the community, and many more
epidemiological and clinical trials. We now have seven clinical
trials funded around the country addressing the issue of stroke
and the minority population. We feel that the involvement of
the local community of minority scientists would be an enormous
help in bringing fresh ideas and methods to the study. But it
is a beginning.
HEALTH DISPARITY
Ms. Pelosi. It is a long overdue beginning, I must say. We
have known for a while about the disparity, but I am pleased to
hear about the initiatives and that Morehouse School of
Medicine is playing such an important role.
Mr. Chairman, as we saw the charts on multiple sclerosis
and the impact of improved instruments and the genome project
and also the need for early intervention that was mentioned in
terms of multiple sclerosis, I think it drives home the point
even more clearly, the need for access to quality health care
for all Americans even more strongly, because to the extent
that we can catch these things early--and if you are not in the
loop of health care, they are not going to be caught early. And
if you can catch it early, the early intervention, as you said,
is crucial.
But the moral responsibility that we have is even greater
since we have so much more opportunity with the genome project
and the instruments, improvements in imaging that we have, that
while we will take these strategies that you have talked about
at Morehouse School of Medicine and all of those discrete
initiatives, it is very positive initiatives, we have to back
up and look at access to quality health care if we are going to
address those disparity issues in this country. If you would
like to comment----
Dr. Fischbach. I absolutely agree. I think it is becoming
even more acute as new therapies, which are going to be limited
initially, surgical therapies, cell implantation therapies,
therapies that depend on very sophisticated technology are not
going to be widespread initially. We have to be sure right from
the beginning these are equally distributed and people have
equal access and an equal voice in deciding about which
therapies can go forward and which can't. So I agree.
Ms. Pelosi. Thank you, Dr. Fischbach, Administrator
Kirschstein, and Dr. Penn. Thank you for your leadership and
for your testimony.
Thank you, Mr. Chairman.
Mr. Istook [presiding]. Thank you, Ms. Pelosi. Obviously,
when you weren't looking, we pulled a little switch on you.
Chairperson Porter had to go on.
Dr. Fischbach, Dr. Kirschstein, Dr. Penn, gentlemen, I am
pleased to be with you. But I believe Mr. Jackson is next. Mr.
Jackson, you are recognized.
Mr. Jackson. Thank you, Mr. Chairman.
I thank you, Dr. Fischbach, for being present today.
The President's fiscal year 2001 budget for NINDS is
$1,100,000,000, an increase of $54,300,000 and a 5.5 percent
increase over fiscal year 2000. Included in this total is
$20,800,000 for the following NIH areas of priorities: biology
of brain disorder, $7,400,000; new approaches to pathogenesis,
$2,000,000; new preventive strategies against disease,
$1,900,000; new avenues for development of therapeutics,
$3,200,000; genetic medicine, $2,000,000; bioengineering,
computers, and advanced instrumentation, $3,100,000; and health
disparities, $1,200,000.
You indicated that in your opening remarks that was an
increase to $24,000,000, which at some point in time in the
not-too-distant future you hoped to move that number to
$26,000,000. My calculation in math--and I may be wrong; I
didn't do very well in math when I was in school--it took us to
24. $26,000,000 is about 2.4 percent of $1,100,000,000.
STROKE RESEARCH
I was reading--I went to a used bookstore this weekend and
bought a number of books on family medical prescriptions--which
I would imagine would be medical school 101 for a lot of
people--because a lot of the language that is used in this
committee are very difficult for me, but I am learning a lot
about the sciences in this examination period.
I was reading under stroke. It said, ``Those at risk,
people who have hypertension and atherosclerosis, are the most
likely to suffer a stroke since both diseases weaken and damage
the arteries. Hypertension probably also encourages hemorrhage.
Heredity may play a role in stroke since the tendency to
develop both hypertension and atherosclerosis appear to be
inherited. Black persons, it says, are more susceptible to
stroke because of high blood pressure, about twice as common in
the black population as in the white population.''
You mentioned some of the work that you are doing at
Morehouse College. While the committee is considering an
increase in your institute for the outstanding work that you
all are doing, I am wondering if, since it is clear that high
blood pressure, for example, is a factor, for example, in
African Americans, what percentage of that increase is being
used for addressing the education associated with high blood
pressure. And since it is clear also that fatty acids or fatty
materials are also a function in slowing down the amount of
blood that gets to the brain, I am wondering if any studies or
RFPs have been issued on the impact of fried food or fried
chicken or fried fish or fried anything and the likelihood that
certain communities are more likely to have their food fried
than baked and, as a result of that, increase the likelihood
that they may one day have a stroke.
Dr. Fischbach. One reason we are focusing on the
predominantly minority schools is we believe these issues are
tremendously important. The best way to intervene in the local
community is by using the local community in trying to
understand these issues better, always emphasizing the quality
of the studies and the investigators involved.
We are proud of the Morehouse program and the five other
programs that we are funding. Several of the epidemiological
studies now underway are addressing issues of diet and genetics
relating to hypertension. The education component of that is
going to be critical. It is going to involve the entire
community outside the medical school.
First, we have to document what we all suspect is the cause
of the hypertension. It is a lot of rumor and innuendo, but we
have to document it with hard data. I think a large fraction of
the studies in our stroke programs will focus on identifying
these factors.
We are also very interested in prevention. Black people do
not only have a higher incidence of strokes, they do worse with
them. If you have a stroke, a black person is more likely to
die with a stroke than a white person.
We have to intervene at all levels and understand the
prevention, the intervention, and the treatment of stroke and
getting that more widely disseminated. All of those account for
big fraction of our increase.
The $23,000,000 and $26,000,000--I just want to add a
note--are related only to this office of specialized
neuroscience programs. We have other programs outside that
office which are also focused on these issues and on other
disparities, including diabetes, trauma, HIV infection. You
know them as well as I do. There are many others.
DIETARY FACTORS AND STROKE
Mr. Jackson. I guess I have one final question. I was
wondering whether or not you were aware of any RFPs that go to
the issue of these fatty foods and a study of diets in various
parts of the population to find out what differentiating
dietary factors might be a factor in incidences of stroke. And
where is the stroke built? You mentioned in your remarks about
stroke built----
Dr. Fischbach. I think many institutes, not so much yet the
neurology institute, have been very interested in diet and the
impact on health. This is a problem that transcends NINDS, and
it is a huge one in the American population. The stroke belt
extends through Atlanta, the Carolinas, Tennessee, through the
southeast. It is most intense--it is called the buckle of the
belt--in and around the Atlanta, Georgia, area. That is the
stroke belt where stroke mortality is 1.5 times as high as for
the rest of the country among whites and blacks. Within the
belt, stroke mortality is 1.4 times higher among the blacks
than among the whites. If you take blacks living in the stroke
belt there is an enormous disparity compared to the rest of the
country.
Mr. Jackson. Thank you. Thank you very much.
Dr. Kirschstein. Mr. Jackson, I have something to add about
studies and activities related to fatty foods. The National
Heart, Lung and Blood Institute in particular has had a very
active program of hypertension outreach and atherosclerosis
outreach with education about diet. They produce a large number
of books about not using fatty foods and perhaps not frying
foods. There is a great deal of work there.
Mr. Jackson. Thank you.
DISSEMINATION OF INFORMATION
Mr. Chairman, if I could add one thing just for the record
to hear, I was shocked to hear that there is a gulf between the
research that these outstanding doctors are doing at NIH and
actually being able to provide that information to surgeons. I
don't know what it is that we can do or what it is that NIH can
recommend on helping us to find a way to help bridge the gap
between the information that you find about--I thought you were
talking about neurological transmitters or something like
that--and how we can actually close that gap, either through
the certification process or the recertification process of
surgeons so that they are current on current information so we
can make their job a little easier.
Mr. Istook. Thank you, Mr. Jackson.
Mrs. Lowey.
Mrs. Lowey. Thank you, Mr. Chairman.
Mr. Jackson, I would just like to say--I don't want to take
time because I wanted to focus on some other areas, but
Secretary Glickman just had an interesting hearing on the
Atkins diet et cetera. This committee and several members on
both sides of the aisle, including myself, have been obsessive
about this issue for a long time. I still wonder why at least a
dozen of my colleagues have gone on Atkins and lost weight,
cholesterol has gone down and they feel great, but I can't
discuss it now. But another time.
I just want to welcome you. As a native of New Rochelle, it
doesn't surprise me that you are a star since it is my
district. I thank you very much for the great success of your
area of expertise.
DUCHENNE'S MUSCULAR DYSTROPHY
Dr. Fischbach, I have in my district a number of families
whose sons are affected by Duchenne's muscular dystrophy, the
most common fatal genetic disorder striking children. As you
know, a child with DMD, like Ben Sernau in my district,
measures his life in months. The parents are, I believe,
understandably frustrated and anguished about the pace of
determining the cause and treatment for DMD. My staff and I
have been researching ways in which we might encourage better
progress. Frankly, we have become frustrated as well. Some say
adding study groups with reviewers who study these disorders
would advance the research. Others point out the lack of
research in choosing to pursue this disorder. How can we
increase the motive and opportunity for DMD research?
Dr. Fischbach. This is something that is actually very
close to my own research and Dr. Penn's before, so I am very
understanding and empathetic.
The gene that is mutant in DMD was discovered 14 years ago.
It was greeted with a tremendous enthusiasm and a sigh of
relief for progress. It has been frustrating for more than a
decade that knowledge has not yet led to improved therapies.
There are many reasons for it. You, being familiar with
families who are very knowledgeable themselves, are probably
aware that it is a very large gene. It is very hard to correct
this gene that can mutate in many different places.
But I do think that in the last year there have been
renewed efforts here by several groups in this country and in
England and some success in introducing a modified healthy gene
back into muscle. So I think there is renewed interest in a
kind of gene therapy and less effort using blood cells as a
source, stem cells, to correct the muscle defect. Muscle is the
largest tissue in the body. So it is a good target for gene
therapy.
There is also some hope, on another front. You probably
have heard of a rather serendipitous finding of an antibiotic,
gentamycin, which seems to improve the outcome of animal models
of muscular dystrophy, and we are sponsoring a trial now using
gentamycin in humans. I think the field will begin to attract
excellent scientists again now that these avenues are open.
We in neurology have talked quite a bit about this in the
last six months. We are re-emphasizing it. NIAMS has a major
interest in muscle disorders. But we want to be better partners
in this. We want to increase our portfolio in this area. I
don't like that word ``portfolio.'' We want to increase our
efforts in that area.
We are co-sponsoring a meeting in May on Duchenne's
muscular dystrophy just for this reason, to invigorate the
field and to get people from outside the field to begin paying
attention to it again. I am hopeful that we will know more late
in the spring.
ALS RESEARCH
Mrs. Lowey. I appreciate that, and I look forward following
up with you on the issue.
As you know, because we discussed it last year, I also have
a great deal of interest among my constituents in ALS. Could
you give me an idea what is the outlook of this terrible
disorder?
Dr. Fischbach. It is a terrible disorder. Right now, you
know, the predictions are rather dire of a 3 to 5 year course
following diagnosis. There is one drug approved by FDA on the
market, an antagonist that seems to interfere with one of the
triggers of the cell death program I mentioned earlier. It
produces a modest prolongation of life.
I think there has been a breakthrough in the genetics of
ALS. A gene has been identified in a few families, less than 1
percent of the patients, but that gene has pointed the way to
defects that may be true of all patients with ALS. We are
sponsoring an effort to develop new medicines based on that
gene. It is a technique that is widely followed throughout the
NIH called high-throughput drug screening. We have a conference
on that in April. It is using large chemical libraries on the
order of a million molecules to screen them for anything that
might affect this mutant gene.
I think now within the last 6 months assays have become
available that make this approach of high-throughput screening
reasonable. I think there is a new interest in new therapeutics
in ALS. But, once again, just like in multiple sclerosis, the
key is going to be earlier diagnosis before these motor neurons
have degenerated too far.
Mrs. Lowey. You also mentioned in your testimony that ALS
and other neurological degenerative disorders have many
features in common, and you have addressed some of them. Can
you tell us a little bit more, or expand on what you have
already told us, as to how these diseases relate and how
research in one area can benefit disorders in other areas?
Dr. Fischbach. It is a wonderful story of discovery in
modern science. It has its home now in neuroscience. It began
with the realization that some cells during very early
development degenerate on cue. It is called a programmed death.
It is part of the normal fate of these cells to degenerate. It
has been discovered that the very same processes occur in the
adult brain when they are challenged or threatened by disease.
It leads to a process that has been named by scientists
apoptosis.
The fact is we know a lot about this process now. Among the
hottest areas of drug development are enzyme inhibitors that
can stop the process. So cells that have been insulted in one
way or another don't necessarily have to go down this death
pathway. The cell death pathway is common in stroke, ALS, and a
number of disorders. We have to find out what is unique about
ALS. Why do these particular nerve cells in the spinal cord
degenerate?
If you had a chance to look at the New Yorker 2 weeks ago
there was an article on discoveries at Johns Hopkins about
local factors that may trigger this death process. It is common
to all of the diseases. That is why I believe, and this is my
own thought, that we ought to declare war on neurodegeneration
in the next 10 years and solve this problem of apoptosis and
neurodegeneration. Even prolonging life by 2 to 3 years would
have enormous impact, and give us enough time to look for the
primary causes.
Mrs. Lowey. I thank you very much and, unfortunately, my
time is up. But I would like to say that many of us feel that
war has to be declared on a lot of fronts. We would greatly
increase the budget to the NIH as much as we possibly could. I
am ready to declare war on that and obesity and a lot of other
areas.
Dr. Fischbach. I am a believer in that diet.
Mrs. Lowey. Thank you.
Thank you, Mr. Chairman.
Mr. Istook. Mrs. Lowey, tomorrow in the defense
subcommittee, we have the Secretary of Defense testifying and
also the chairman of the Joint Chiefs. You may want to attend
that hearing as well.
I certainly appreciate--we know there is a lot of hearings
we get into regarding NIH because there is such a great
interest not only but by this panel and Members in Congress but
by the American public in what is going on, medical research.
We certainly appreciate your commitment and devotion to that,
and I thank you for taking the time this morning.
Mrs. Lowey, was there anything further?
Mrs. Lowey. No. Mr. Jackson left, otherwise----
Mr. Jackson. I have no questions, Mr. Chairman.
POOR DIETARY HABITS
Mrs. Lowey. I would like to say that I am very serious
about following up because I have personally participated in
dozens of conversations, Mr. Jackson--as Dr. Kirschstein
knows--on the whole issue of diet and health and disease. I
think what is very puzzling and very troubling is that there is
so much conflicting information. So for someone like myself who
can start the morning on Atkins by the afternoon you have done
something else and you neutralize the benefits of every one of
them.
Mr. Istook. It depends on what you want right then.
Mrs. Lowey. Exactly. You know that. We have talked about
that. I mean this very seriously, because we see the connection
between poor dietary habits and health. I do hope that,
although there have been dozens and dozens of studies and
reports, that somehow we can gather this information and
present it in a persuasive way. Because although the low fat,
vegetable, et cetera, diet seems to be endorsed by the NIH,
there is evidence--maybe it is circumstantial and anecdotal--
from those who are committed to the Atkins diet, and they walk
around with high fat diets--I forget if that was the one you--
--
Mr. Istook. No, no.
Mrs. Lowey. So I look forward to additional research so
that we all can become better informed, and then we have to
deal with the behavioral issues so we can act on the knowledge
that is available. Let me thank you again for the important
work that you are doing. Thank you.
Mr. Istook. Thank you, Mrs. Lowey.
We thank you, and we stand adjourned.

Mr. Porter. The Committee will come to order. We continue
our hearings on the National Institutes of Health and its
fiscal year 2001 budget. We are pleased to welcome this
morning, Dr. Richard Hodes, the Director of the National
Institute on Aging. Dr. Hodes, it is good to see you. More
members will come back because we just had a vote on the House
floor. Why don't you proceed and then we will follow with
questions.
Opening Statement
Dr. Hodes. Thank you. Let me begin by introducing those
accompanying me. At the far left, Colleen Barros, the Executive
Officer of the institute, Dr. Terrie Wetle, Deputy Director,
and Karyn Ross, the head of our Financial Management Office.
Mr. Chairman and members of the committee, it is a pleasure
to have an opportunity to appear before you again. Since the
inception of the National Institute on Aging some 25 years ago,
there has been truly great progress in understanding the basic
biology of aging, in developing interventions to avoid aging-
related disease and disability, and in understanding the ways
in which the quality of life for older Americans can be
improved. The pace of this progress has been impressive, and I
welcome this opportunity to share with you some of the most
recent progress as well as a description of current research
opportunities.
ALZHEIMER'S DISEASE
One of the very great threats to quality of life among
older Americans remains Alzheimer's disease, a devastating
disease which tragically affects some 4 million Americans at
present. With the current projection for an increase in the
numbers of individuals at highest risk, namely 85 and older, a
population which will increase to an estimated 20 million
Americans by the year 2050, the urgency of solving this problem
has increased.
The National Institute on Aging, as the lead Federal agency
for AD research, has taken this impending public health crisis
seriously. On the basis of recent research-based findings,
enabled by the recent budget increases in the fiscal years 1999
and 2000, the institute has announced the initiation of an
Alzheimer's disease prevention initiative, consistent with
congressional language and in partnership with other public
agencies and the private sector.
In 1999, the first large-scale prevention trial was
initiated for Alzheimer's disease. In this trial, individuals
with a diagnosis of mild cognitive impairment, that is
individuals who suffer minor memory impairment but without
actual dementia, will be treated with either vitamin E or
Aricept, to determine whether it is possible to delay or
prevent the onset of disease.
This trial will take place in some 65 centers across North
America and should offer an answer as to the efficacy and
prevention rather than treatment of this devastating disease
where it would appear that the most hope lies to arrest this
disease at an early stage.
Similar trials, funding permitted, will be initiated over
this year and in connection with agents such as anti-
inflammatory agents and antioxidants and estrogen. In order to
identify individuals at risk and to monitor disease at early
stages, it is critical to develop means for detecting the
changes that occur in the brain prior to the development of
symptoms. Brain imaging that has developed over the last year
offers enormous potential for this. One example shown on the
first poster illustrates recent success in defining the area of
the brain called the hippocampus, which is critically involved
in memory and which is selectively affected in Alzheimer's
disease.
[The information follows:]
Dr. Hodes. What you see on the panel at the left, in the
normal 25-year-old brain, indicated in red, is the relatively
large size of the hippocampus in younger adults. The most
marked contrast is with the picture on the right, where
individuals with Alzheimer's disease have much reduced volumes.
If one looks at 75-year-olds who are normal, there is
relatively little change in the size of the hippocampus
compared to younger adults, and in the intermediate group, mild
cognitive impairment, you can see there is an intermediate
decrease in size. The quantification of that decrease is
actually a strong predictor of the risk of subsequently
developing Alzheimer's disease.
In a research setting, we identify individuals at high
risk, and hopefully use this information to monitor the success
of therapeutic or preventive interventions. In order to enhance
our approach to Alzheimer's disease, an important component of
research is that which is focused on the basic underlying
genetic and cellular mechanisms. In the past year, again, there
has continued to be great progress in that area. Some of that
is illustrated on this slide.
[The information follows:]
Dr. Hodes. From the time that Alzheimer's disease was first
described by Professor Alzheimer in 1906, one of the
characteristics of the brain was that of the so-called amyloid
plaque. Up in the top right corner is an illustration of that
plaque. What has developed over past years is strong progress
in understanding what leads to the development of these plaques
and their precursor and antecedent products. Illustrated here
is the fact that discovered in the last year are two enzymes
called beta secretase and gamma secretase, illustrated as
scissors here because their action is to actually cut from a
normal protein in all cells the beta amyloid. The result of
that cutting is to generate the peptide which forms amyloid
plaques.
The promise of understanding the chemistry that creates
these plaques now offers an opportunity to intervene in an
attempt to arrest and prevent the development of amyloid
plaques with a strong hypothesis being that this will, in fact,
be directed at the most basic molecular underpinning of
Alzheimer's disease itself. Basic science discoveries of this
sort and others will be a primary priority of the institute in
their translation into interventions to prevent and arrest
Alzheimer's disease.
BIOLOGY OF AGING
Similarly, studies of the basic genetic and molecular
biology of aging have elucidated a great deal about the
underlying mechanism of normal aging as well as its
pathologies, as illustrated in the next visual.
[The information follows:]
Dr. Hodes. That is the identification of genes, which in
experimental systems are capable of having marked effects on
how long organisms live. In this case, the experimental
organism is C. Elegans. In the graph shown on the right there
are two lines. The first of them with the open circles
indicates the survival curve of normal or wild types of C.
Elegans, which show that they nearly all died by 20 days of
age. In contrast, the results of a single mutation in a gene,
aptly named age 1, results in an extension of life to a nearly
doubling of life span.
What is particularly interesting is that when one examines
a panel of such mutations as discovered in experimental
animals, they have close homologues or similar genes in the
human. Moreover, the genes that have been identified as
illustrated in this selective list on the left form an
interesting pattern, in this case in coding the genes for
insulin receptors and the molecules that are responsible for
the metabolism of insulin and glucose. This suggests that
longevity in experimental animals may shed a good deal of light
on the underlying processes in disorders such as diabetes and
control of weight and metabolism important to human aging as
well.
REDUCING DISEASE AND DISABILITY
These and other discoveries will be applied to the
development of meaningful interventions to avoid disability and
prolong the quality of life into later adult years. Until a few
years ago, it was widely thought that the increased number of
older people in our society was going to carry with it an
inevitable burden of increased disability. I think it was in
1997 before this subcommittee, we had the opportunity to first
report initial studies which indicated that this was not true,
and in fact, since 1982, there had been a marked decrease in
the rates of disability among older Americans, age 65 and
older.
On the basis of more recent research, it is gratifying to
be able to report that not only have these findings been
sustained and supported by additional studies, but that the
trend towards decreasing disability rates in older Americans
continues through the present, and that it appears to be shared
by both genders, men and women, as well as by minority and
nonminority populations. A high priority of the institute at
this point will be to further understand what factors have
contributed to this decrease in disability and to use such
information in designing strategies to sustain and accelerate
that trend.
It is increasingly clear that among the factors that are
important determinants of quality of life and life expectancy
are behavioral features that include physical conditioning, and
the variable of exercise, which has now been shown to have
positive effects in a remarkable spectrum of disease,
including, for example, osteoarthritis and depression. Exercise
has been shown in experimental animals to actually increase the
number of brain cells formed in adult and even older adult
animals. In humans, exercise has been shown to increase certain
high-order cognitive or intellectual abilities.
[The information follows:]
Dr. Hodes. There also appears to be a strong connection to
overall survival and risk of disease. Illustrated here is the
result of a study that was reported last year in which nearly
10,000 individuals, ages 20 to 82, were studied for physical
fitness by measures such as treadmill performance, and then 5
years later were reexamined by the same tests. Individuals,
following that test, were studied for their subsequent survival
and susceptibility to disease. What is illustrated here is the
relative risk of cardiovascular mortality, that is, death from
cardiovascular disease.
If you look first at the higher light blue curve to the
left, that bar indicates the high risk of disease in
individuals who are noted to be unfit to unfit, meaning that at
the first examination they were unfit and they remained so.
In the right in orange, the lower bar, is the much lower
risk of mortality in individuals who were fit at the time the
study began, and were fit 5 years later. But perhaps most
important of all is that middle bar in blue labeled ``unfit to
fit.'' This is a group of individuals who were not fit at the
time the study began but who, 5 years later, were fit. Remember
these are individuals who were 60 years of age and older at the
time of the study and who, as a result of this change in
physical fitness, had a reduction of nearly half in their risk
of cardiovascular mortality. This is an important suggestion
not only that fitness can be protective against disease, but
that it is not ever too late to start, and that changes in
behavior, even late in life, can have important impacts.
REDUCING HEALTH DISPARITIES
On the background of lessons being learned and their
application to the quality of life in older Americans, the
variable of health disparities is one that looms heavily for
all of us. It has been found, for example in the past year,
that on top of the very high quoted and identified rate of
Alzheimer's disease among nonminority populations, that the
risk of Alzheimer's disease in both African-Americans and
Hispanic populations is higher still.
Moreover, in trying to understand both genetic and risk
factors for Alzheimer's disease, it appears that the risks for
various minority subcomponent populations may not be identical
to those in nonminority populations, so that it is critical to
look at both genetic and environmental factors across
components of populations to best understand the risks that
people have, and to address them.
More broadly, since about a year ago when we first had an
opportunity to meet with Mr. Jackson to discuss our plans to
initiate a widespread strategic planning effort for minority
research, we have carried out, with the help of a panel of
distinguished outside advisors, an assessment of current and
projected research in areas of health disparities and minority
research. We are awaiting in April the report from that study
which we look forward to sharing with the public and with
members of this committee.
CONCLUSION
Mr. Chairman, overall, until a short time ago, there was
little that could be offered by way of interventions to modify
the diseases and disorders that accompanied aging. Over the
past years the situation has changed dramatically and we look
forward to similar opportunities in the future.
It has been a privilege, I must add at this point
personally, to have had the opportunity to testify before you
as well as the rest of the committee over these past years. The
President's proposed budget for fiscal year 2001 for the
National Institute on Aging is $721,651,000, and it will be a
privilege to respond to any questions that you may have.
[The written statement of Dr. Hodes follows:]
ALZHEIMER'S DISEASE
Mr. Porter. Dr. Hodes, thank you very much. Can you put
your first chart back up there.
As you were testifying, I was thinking as to how large your
own hippocampus must be because you always testify a cappella,
and I don't know how you do it. You cover so much ground
without a single note, and it is very impressive, Dr. Hodes, I
must say. I want to ask some questions about some of the things
that you said. You said that you are going to have an effort to
identify things that might prevent the onset of Alzheimer's
disease, and there were three different compounds. One was
vitamin E.
Dr. Hodes. I referred to a study initiated last year in
which two agents were being tested, vitamin E, which is in the
category of antioxidants, and the drug Aricept, which is a now
FDA-approved drug. I also alluded to the fact that there were
future projections to take advantage of the fact that three
categories of agents showed promise in the area of prevention.
One of them is antioxidants which would have included vitamin
E, another anti-steroidal, anti-inflammatories and the third,
estrogen.
Mr. Porter. How do you know that vitamin E might be
something that would help? In other words, how did you get to
the point of identifying this as one of the possible----
Dr. Hodes. That is an interesting question. For each of
these categories, the balance of evidence is somewhat
different. In general, the two broad categories of evidence
that one can conceive of are those which are epidemiologic,
that is, clues as to what seem to be risk or protective factors
from observational studies, and the other, the broad category
of basic science that will look at molecular structural events,
and from those, deduce what might be protective. So that, for
example, in the case of estrogen, the primary drivers come from
both categories. That is, epidemiologic studies suggested that
if one analyzes women who either have or have not had a history
of using estrogen replacement following menopause, the risk of
Alzheimer's disease is about half in those women who have a
history of having taken estrogen versus those who have not.
I will have to quickly add that we don't know if that is a
causal relationship or if it correlates with other factors that
we are not able to identify. That is why we need to conduct
controlled clinical trials to look for direct evidence of
efficacy.
Estrogen is also known to have trophic effects, meaning it
can influence the growth of nerve cells in tissue culture.
There are receptors for estrogen in the brain, so there is a
convergence in this case of epidemiologic data and basic
science data.
For antioxidants, the data are more heavily from basic
science studies where there is evidence that oxidated damage
occurs in the brain, increasingly in Alzheimer's disease and so
agents which could prevent that might have an effect.
In the case of the nonsteroidal anti-inflammatories, again,
there is evidence from both directions. So individuals who have
taken drugs such as ibuprofen for a variety of reasons,
arthritis and other diagnoses, also have something like a 50
percent reduction in apparent risk of Alzheimer's disease, but
once again, we don't know if that is causal. Similarly, there
is evidence for inflammatory processes in the brains of
individuals with Alzheimer's disease. So again, there is a
convergence of basic science and epidemiologic data to suggest
that this is a promising candidate, but one that is certainly
not an established effective one until we have the results of
direct clinical trials.
MILD COGNITIVE IMPAIRMENT
Mr. Porter. When you look at the chart, what is normal at
age 75? In other words, how many people at age 75 as a
percentage of the total fall into the latter two categories?
Dr. Hodes. The precise numbers, the prevalence, really
cannot be given with accuracy, certainly in terms of imaging,
which has not been done on a sufficiently large number of
people to make it a population study, to determine what is
``normal.'' Those data will be forthcoming as there is more and
more experience applying these techniques.
Mr. Porter. So it might be 10 percent fall into the other
category? You might find this in 90 percent?
Dr. Hodes. Possibly. I should note that the definition of
mild cognitive impairment has been classified only recently. So
this is a real element of progress and research. Only in the
past years were definitive studies published, which indicated
that criteria could be set that reliably identified individuals
with mild cognitive impairment, and as a correlate of that
demonstration was the realization that individuals in this
category were at high risk for developing Alzheimer's disease.
So if one looks at individuals with mild cognitive
impairment, there is a risk that approximately 14 to 15 percent
per year will go on to develop Alzheimer's disease versus a
less than 1 percent risk in the same age group of the general
population without mild cognitive impairments. This becomes a
strong predictor of impending Alzheimer's disease.
LIFESTYLE AND HEALTH
Mr. Porter. Much of what we are seeming to find about
disease and about health comes back to us in a way that we all
say well, that is logical. Having a good diet, avoiding toxins
of one type or another, such as the use of tobacco, exercising,
it all seems very logical. We ought to say, gee, that makes
good sense. Knowing as much as we do about the effects of bad
lifestyle, if you want to call it that, are we doing enough in
prevention to keep people healthy long into their later years?
Are we, with all of this knowledge, seeming to look into a lot
of ways where we can develop pharmaceuticals of one type or
another as substitutes for really good living?
Dr. Hodes. That is a very important and insightful
question.
First, I think all of us, perhaps sometimes scientists
above all, are too ready to indicate that something was obvious
after the fact. But, as you pointed out, for example, in the
area of exercise, until not so many years ago, the wisest of
clinicians taking care of older people advised that older
people were frail and needed to be careful and should not
exercise too much. There are cases in which we thought that we
knew what made sense, such as the use of antioxidant vitamins
that remain an area of real controversy. As you know, there are
studies that used some these agents in cancer trials. They
turned out in particular studies to not only not have positive
effects, but to actually be detrimental. There is reason for us
all to be cautious about the basis upon which we make
recommendations.
But the real meat of your question is in those cases where
we have things that not only make sense but where that sense
seems to be sustained by the best objective evidence that we
can muster, are we doing enough to translate that into changes
in behavior? The answer is clearly that we are not, and that
emphasizes a couple of points. One, I think, is that not only
is the molecular biology and the hard bench biology that we
stress a critical science, but so are aspects of behavioral
science. It simply is not as easy as it would appear to let
people know what is good for them and expect that they will be
able to comply.
That is the reason why across NIH and certainly within NIA,
there is an important research program in the behavioral
sciences trying to understand the most effective ways of
encouraging people to initiate and then sustain productive
changes in lifestyle. We have an obligation to communicate to
the public in the case of exercise, for example. One component
of our attempt to communicate the science base has been in the
recent publication of an exercise manual which has received
enormous demand from the public. In response to availability of
this as a free document to individual requests by citizens in
response to a phone call or postcard, we have now distributed
over 300,000 copies of this publication and will continue to
monitor not only its use but the impact that it is having on
the public's behavior.
Mr. Porter. Dr. Hodes, this is a comment for both you and
Dr. Kirschstein. The 300,000 people that called are probably
people that care enough to do the right thing in the first
place and the ones who don't call are the ones that you really
need to reach. It is hard to get from where you are to where
you want to go. I know that NIH's primary responsibility isn't
public health or changing lifestyles, but increasingly, it
seems to me that we need to make a connect between the
knowledge base that we are gaining all the time about that
subject and getting people to change their lifestyles to be
more healthy and save all of the health care costs that follow
if they don't.
I am in discussions right now with CDC, HRSA, SAMHSA, and I
will be including NICHD to talk about what we can do to get a
message in places where people can be reached about children's
lifestyle. Getting kids started at a young age with good
exercise, good diet, avoiding the toxins and all of the rest.
But I think what I would like to see is a greater coordination
between these public health agencies and NIH and a real effort
made to broaden that, to reach older people who ought to be
influenced by this knowledge base and change their lifestyles
as well because as you said, it is never too late. You can pick
it up even if you are 65 or 70 years of age and live a much
more healthy and longer life.
So I would like to really get NIH and the public health
agencies, particularly CDC, working together on this and really
try to impact people with the knowledge we have instead of, you
know, putting it on the shelf and saying now we know it, but
what are we going to do with it? That is just a comment.
Mrs. Northup.
COMPLEMENTARY AND ALTERNATIVE MEDICINE
Mrs. Northup. Thank you, Mr. Chairman. I appreciate your
final comments, Mr. Chairman, and I think as a mom I am really
good at nagging. I have gotten good over the many years that I
have practiced it. I am always finding myself saying to my kids
if tomorrow they invent a cure for diabetes, give everybody
liposuction, hook you up to a machine and it exercises every
muscle, you still won't be as well off as if you drag yourself
out of bed, walk 2 miles, choose bran instead of pancakes and
so forth. But it is not what any of us choose. I would just as
soon hook myself up to a machine as go out and run or walk,
too. So I think it is a real hard sell. And it is a lifetime
sell. I think sometimes we hope that there will be the magic
cure, as I certainly do for AD, and I want to ask you about a
couple of magic cures right now, but I thought I would just say
first of all, I know that there is no magic cure. I wondered
how many of your studies have involved nonpharmaceutical
efforts? For example, if you get any of the magazines, the
health food magazines, there is another thing you are supposed
to take every single month. And most--an increasing number of
50-year-olds are taking.
So I am wondering if memory enhancers, vitamins or gingko,
if you study those? I know that you have like a nonmedical area
or unconventional therapies now that thyroid is seen as maybe
something that declines as you age, there are now thyroid
enhancers. I wonder, first of all, about the safety of those
and about the efficacy of them? Is your institute working in
that area?
Dr. Hodes. These are very important areas where we are
certainly working very heavily. The general caution to the
public in the face of a barrage of recommended interventions
was, for example, the topic of a public service video that was
produced a couple of years ago. I mention it because it
actually won an Emmy, and this was a first for a product by a
Federal agency winning such an award in that category. It was
meant just to alert people to be cautious and provided them
with phone numbers to access information facilities which the
institute sponsored so we could provide what information was
available. We work very hard to try to understand the merits of
any potential interventions, whether they come from
conventional or unconventional sources.
In response to your specific question about ginkgo biloba,
there is currently a controlled clinical trial underway that is
carried out with collaboration between NIA and the Center for
Complementary and Alternative Medicine. We certainly need to be
very careful not to reject out-of-hand promising alternatives
of any sort, but we are committed to making sure that they are
assessed in the most objective way.
We are confronted with circumstances in which many of these
products are available without prescription in an unregulated
way, and that puts a unique burden on us to provide
information. That is sometimes difficult because the background
use of some of these agents in the population confounds efforts
to do systematic studies. We appreciate the importance and are
very committed to looking at these nonpharmacologic
interventions. Another whole category is that of behavioral
interventions themselves, and there we alluded to studies on
exercise, which is a very important example. There are others
as well. For example, treatment of a very common and costly
problem in older people, women predominantly, men as well,
incontinence. There have been some recent studies, which
indicate that behavioral interventions are actually somewhat
more effective than pharmacologic interventions, are better
received by the individuals with a problem, and now provide an
important alternative to a drug or a pill.
Mrs. Northup. But you don't recommend any of the non--or
the alternative medicines for Alzheimer's disease? If you had
a--parents in their 70s, would you recommend that they take any
of the alternative medicines?
Dr. Hodes. The only positive result from a controlled
clinical trial that reached the level of statistical
significance was one reported a couple of years ago. It was an
NIA-sponsored trial which looked at vitamin E for individuals
who had relatively advanced Alzheimer's disease. Vitamin E had
a very modest effect on delaying, on average, the time until
adverse consequences, such as death or institutionalization or
loss of independence.
Interestingly and sobering for investigators in the field,
the same intervention had no detectable effect on measures of
cognition. So all in all, there was a modest effect of that
agent indicating that it would not be irresponsible for a
physician or health care provider looking at such information
to decide that the agent might have some efficacy. That is
really the only one on which there is an equivalent such basis
of data, and again, I emphasize the effects are very modest.
MILD COGNITIVE IMPAIRMENT
Mrs. Northup. Let me ask you, when you say mild cognitive
impairment can be a predictor of AD, is it that or is it just
AD in the earliest stages? And let me say, Mr. Chairman, in the
latest, or in a couple of old-week Newsweek Magazine or Time
Magazine, the statistic was that 50 percent of all seniors, 85
and older, currently have AD. From 75 to 84 it was 20 percent
of all in that age group, 50 percent over 85.
Dr. Hodes. Yes, those two numbers and the 3 percent in the
65-to-74 age were numbers that were actually shared with this
committee when they were reported some years ago. They came
from the first study of that kind done in East Boston. Other
studies would have quantitative differences in the numbers, but
I think they all agree that it is a shockingly high percentage
of individuals, 85 and older, who have Alzheimer's disease and
who are at risk.
The question that you ask about whether mild cognitive
impairment is really just an early stage of Alzheimer's disease
or not is an important one that many of us have asked. I think
that the answer is not known. I quoted a figure that per year,
14 to 15 percent of individuals with mild cognitive impairment
develop Alzheimer's disease. Presumably, if one were to follow
those individuals for enough years, either 100 percent of them
would develop Alzheimer's disease, and that would support the
suggestion that possibly it is just an early stage of
Alzheimer's disease, or we would find that there is a subset of
them that never go on to Alzheimer's. That, in itself, would be
an important observation in trying to understand the difference
between Alzheimer's disease and mild cognitive impairment. At
this early stage of research, we don't know which of those two
is the correct answer.
Mr. Porter. Thank you, Mrs. Northup.
Mr. Hoyer.
DECLINING DISABILITY RATES
Mr. Hoyer. Thank you. Doctor, I looked at your testimony
quickly and I apologize for being a little late.
What should we expect as a society in dealing with old age?
And by that I mean if you could describe the optimum attainment
through medicine and lifestyles, behavior, what would that
optimum be? Presumably we are all going to die. Now do we get
to a point where we turn off the switch, we have been healthy,
our minds are strong and everything or is there an
inevitability about the deterioration of the human
physiological being?
Dr. Hodes. First, I would regrettably concur with your
first conclusion that we are all going to die. And that does
raise the issue then of what the optimum outcome is for aging
research aimed at improving the condition of older people. And
I think it clearly is to minimize the total amount of disease,
disability, the amount of time spent until death in a condition
of lessened independence. Is that realistic or not? Some of the
data that I alluded to about observations of decreased rates in
disability are very heartening. They suggest that having people
live longer is not a guarantee that they are going to spend
more time disabled. There are studies in progress that attempt
to break down the increased life expectancy that we now enjoy
into periods of extended life without disability and periods of
life with disability.
Again, part of the heartening news is that we are not only
increasing life, we are increasing the years of life without
disability. Certainly our objective is to minimize disability
until the final stages of life and ending in death. The ability
of behavioral interventions versus drugs, high technology and
other factors to contribute to this is not at all clear. Part
of the research that we need to pursue is what each factor
contributes. Clearly behavioral aspects can, clearly high
technology can. Public health measures, education, all are
contributing.
The precise mechanisms by which each plays a role are the
subject of current study and are important priorities for what
we continue to support.
COLLABORATION WITH OTHER NIH INSTITUTES
Mr. Hoyer. What impact do you believe that the research
your institute funds and the results have on the other
institutes? In other words, what is the cross-fertilization
between your institute and the other institutes? My thought is
if a lot of the findings that you come up with internally or
externally do in fact impact on what, for example, Dr.
Alexander is going to be thinking about, what are kids going to
be facing? How perhaps--if they are bad consequences, do we
avoid them? And, if they are good consequences, how do we
enhance them?
Dr. Hodes. I think you are absolutely right. I should say
that the background level of collaboration across NIH is
extraordinarily good. As you allude, in the Aging Institute, we
have a yet higher standard and relevance of such interactions
and collaborations. You are correct that with the Child Health
Institute, there is the issue of life course in both
directions, the ways in which events in early life influence
the health status of older people, the way in which older
people impact on the development of children.
Many of the primary problems faced by older people are also
very much at the center of the mandates of other institutes.
Some of the studies that I was able to present in earlier years
allude to the effects of controlling blood pressure on a number
of outcomes. These studies were appropriate collaborations
between the Heart, Lung and Blood Institute and NIA.
In the area of cancer, we are collaborating with the
National Cancer Institute because cancer is predominantly a
disease of older people. In the case of diabetes and
musculoskeletal disease and on and on, these are natural and
compelling collaborations with other NIH Institutes. In many
cases we are taking advantage of the collaborations in very
explicit ways to conduct studies that neither institute could
sustain optimally on its own, not only because of budgetary
constraints but because the expertise that comes to bear on
some of these problems is complex and the collaborations are
far better than the impact of individual institutes.
So you are absolutely correct that it is important that
these collaborations occur, and I think in large measure they
are. I am sure there is room for improvement and we are
constantly looking for new opportunities.
Mr. Hoyer. Doctor, I had questions on Alzheimer's disease
but your statement was thorough and your responses to the
chairman and to Ms. Northup have been pretty thorough so I am
not going to repeat them. Let me make an observation, though.
The name of your Institution, the National Institute on Aging,
is appropriate--as opposed to the National Institute on Aged. I
think we need to redefine when old is old, and maybe I have a
personal interest in this, of course, as does the chairman. Not
Mrs. Northup, of course, as she is much younger than the
chairman and I.
Mrs. Northup. Well, I can at least keep my hair brown.
Mr. Hoyer. But I think our concept, as life expectancy
grows, will fit in with fitness of the psychological, because I
find that I have a lot of friends in my age group who think of
themselves as pretty young, myself included. We do a lot of
things, and there are other people who keep talking about
themselves, well, I can't do that at my age. I frankly think
that is the first step toward going downhill.
What I am saying is that I think the concept of what old is
needs to change. But it is a concept that is tied to my first
question, which asked how long can our physical bodies sustain
a healthy, active vibrant life? Obviously our own observations
indicate that is very different. I had an aunt in England who
wrote me regularly until the age of 96. In the last 6 months
she went downhill pretty quickly and died just after she turned
97. Up until that time, she was obviously both young of mind
and fairly young of body. The psychology of what is old is
something that we need to deal with as well. Thank you, Mr.
Chairman.
Mr. Porter. Thank you, Mr. Hoyer. I think we have time for
one more question each if we would like to do that. I would
like to ask a question. Can we go back to the chart that showed
glucose metabolism.
Dr. Hodes. That is the slide of genetic mutations.
Mr. Porter. There has been a study that indicates that if
there is a substantial reduction in caloric intake and I think
it was done on mice, and I mean 30 to 50 percent, that that is
something that leads mice to live longer and appear more
vigorous and less prone to disease. Is that part of this
approach and what does that tell us about the role of diet and
weight in longevity?
Dr. Hodes. That is an excellent question, Mr. Porter. Yes,
you are quite right. The observation which has been consistent
over some 30 to 40 years now has been in rodents, mice or rats.
The one reproducible intervention which will extend maximum
life expectancy, and that is an interesting distinction, not
just avoid disease and let animals live to the usual life
expectancy without dying prematurely, but actually extend
maximal life expectancy, is caloric restriction.
Typically, this has been done by comparing a group of ad
lib-fed mice or rats, which means that they have all of the
food that they want all of the time, with a group that has
caloric intake restricted by typically 30 to 40 percent below
that level while maintaining nutrition, so they are not
malnourished animals. And the impact of this is to increase
maximum as well as average life expectancy by some 30 to 40
percent over a series of studies.
Mr. Porter. What implications does that have for human
beings?
Dr. Hodes. That is precisely the question that we are now
trying to address. Some have taken that evidence to mean that
it must apply to humans as well, and the fewer calories one
eats, the better, but it raises much more complex questions. We
don't know, for example, whether the critical variable is
maintaining an appropriate body mass, for example, low in fat
and ideal weight, however you achieve that, or whether there is
a distinction between whether one achieves weight control by
exercising but perhaps eating more to maintain weight, or by
simply reducing caloric intake. To translate those animal
studies, then, to these important human relevant questions is a
very specific initiative. In this year, we will be funding in a
more extensive way studies to try to understand these
calorically restricted mice and rats, and on the one hand,
analyze biologically what is going on and what the impact is of
this caloric restriction to see if we can understand the
variety of ways in which they might be reproduced in humans. At
the same time we will be trying to look at pilot studies that
will compare exercise interventions with voluntary caloric
restriction, not an easy study to do in humans, to determine
whether in the human condition what occurs will mimic what has
been observed in the rodents.
There are also studies that are ongoing in nonhuman
primates who are being subjected to caloric restriction as
well. I have to stress that these animals are being well
treated. They are receiving full nutrition and are under
physically optimized conditions, but they are given a percent
decrease in calories. Because of the life span of these
animals, it will take some additional years before we know the
final impact on life expectancy, but early suggest that calorie
restricted animals are healthier. They have lower levels of
lipids, lower sugar, better insulin responsiveness, which gives
reason to have serious interest in seeing whether in nonhuman
primates positive effects on longevity and health might be
achieved.
Mr. Porter. And they might outlive the scientists who are
performing the experiments.
Thank you, Dr. Hodes.
Mrs. Northup.
NUTRITION
Mrs. Northup. Well, I would like to follow up on that. Let
me first of all make one statement, and that is, I hope that
you will use multidisciplinary efforts beyond science, basic
science, that you stretch out to the psychology department, the
sociology department, in order to--but that is not the question
that I have.
I want to ask if you have looked at the Atkins diet in
terms of what you are just talking about, because as you know
the rage--first of all, it was my kids who came home from
college, everybody on Atkins, and it made you sick watching
them fry bacon and eggs and stuff for breakfast. Now it is the
seniors. He has gone into the senior population and claims that
it is sugars that age you and cause obesity, not fats. If you
see the new books and everything, his claims and there are--he
gives lots of examples, and I just wonder, if that is a type of
approach that you've looked at, the high protein, low
carbohydrates?
Dr. Hodes. I am aware of the publicity and popularity, but
the answer to your question directly is no, at least in the
National Institute on Aging. We have not carried out studies
trying to reproduce diets of that composition for their impact
on an experimental system.
Mrs. Northup. It worries me to see such a popularity of
these types of things that we talked about--the ginkgo and so
forth. While all of the people that we are seeking to serve
are, in large numbers, pursuing sort of self diagnosis and
treatment. It seems like science ought to at least try to keep
up with that.
Dr. Kirschstein. Mrs. Northup, nutrition is an area that is
supported by many of our institutes as you will hear when the
Heart, Lung and Blood Institute comes tomorrow, Diabetes and
Kidney Diseases, the National Institute of Child Development,
this afternoon. We set our course as to how we eat, as you well
said, based on how we teach our children to find appropriate
nutritional activities. A lot of this is coordinated through
the nutrition coordinating committee. The lead institute is the
National Institute of Diabetes, Digestive, and Kidney Diseases.
There is also an Office of Dietary Supplements, and we will
talk about that when we testify March 8. So there is a great
deal of activity, and much of this is being looked at. I don't
know the details, but the institute directors will be able to
tell you.
Dr. Hodes. Mrs. Northup, I will add that the ability to
respond to areas of public interest which have promise and/or
are advertised to have promise for so-called anti-aging effects
as well as a variety of others creates an imperative that we
realize. With funding which we have been fortunate enough to
receive this year we will be able to initiate an infrastructure
for the testing of such compounds in which we will have in
place investigators most expert in rigorously carrying out the
interventions and measuring impact on life expectancy and on
disease at intermediate end points. Thus we can attempt, with
as much scientific validity as possible, to be responsive first
at the preclinical experimental level and ultimately at the
level of human interventions to some of these myriad of claims.
Mr. Porter. Thank you, Mrs. Northup.
Mr. Hoyer.
NIA SUCCESS RATES
Mr. Hoyer. Doctor, we talked about pay lines yesterday.
What are your pay lines projected to be under this budget
compared to this year or the year before?
Dr. Hodes. If I could quote success rates, which you know
are the parameter most widely used to reflect what you are
using, last year in fiscal year 1999, our success rate was
approximately 28 percent. This year it is projected to be
approximately 22 percent, and next year under the President's
budget it is projected to be approximately 17 percent.
Mr. Hoyer. Now, that is quite a reduction. Yesterday we
heard that one of the issues impacting that was the increased
dollar value of the particular grants. Can you relate it,
therefore, to the number of grants that are given and the value
of those grants?
Dr. Hodes. Yes. Certainly in the case of the National
Institute on Aging one of the contributors to a projected
decrease in success rate is an increase in average cost. As you
heard yesterday, it reflects a number of variables, in part,
the success of the research enterprise. As we are able to
translate basic science studies to interventions in clinical
trials and studies, those become increasingly expensive, as
well as the fact that many of the costs of basic research are
increasing at a rapid rate. The competition between supporting
research that is expensive but valid, and weighing that against
a success rate that is sufficient that it will not discourage
investigators, particularly a new generation of investigators
coming into the field, is a consideration that I think all of
us across NIH are constantly engaged with.
Mr. Hoyer. In terms of numbers, can you give me that or
provide that for the record? 28 percent--do you recall in the
ballpark how many grants that was? And how many 16.7 percent
is? If it is 16.7 percent of 1,000 applications, that is better
than 22 percent of 500 applications?
Dr. Hodes. Yes. Although the denominator is going up
slightly, it is not going up enough to maintain the number of
successful grants. So 398 was the number actually funded in FY
1999; estimated this year, 389; and next year's estimate is for
a true decrease to 315.
Mr. Hoyer. Now, I presume--I asked Dr. Kirschstein some
questions with reference to the 3,000,000,000, and the
7,000,000,000 and also to the incremental----
Dr. Kirschstein. We are working on that.
Mr. Hoyer. I didn't expect you to have that now. I didn't
mean to imply that. I just asked it yesterday or the day
before.
But clearly one of the things--if Joe Early were still
here, he would be appalled by this reduction. For Mrs. Northup,
he was a member of this committee for many, many years and
clearly was the expert on NIH, immersed himself deeply in NIH
and knew a lot about it, and clearly was its most tenacious
advocate on our committee. But he was always very concerned
about pay lines because he thought it would have a direct
impact on what you referenced, the discouragement or
encouragement of young researchers to go--to believe that there
was an opportunity for them in basic biomedical research
because pay lines were going up and because the percentage of
applicants were greater.
Dr. Hodes. I think in that regard, one thing that all of us
are doing in addition to generally paying attention to overall
success rates is to, in particular, give close scrutiny to the
status of new investigators entering the field. Dr. Kirschstein
can speak to the NIH-wide profiling of that, but we have been
very careful, and so far gratified to find that there has not
been a substantial decrease in the number of new investigators.
It is a critical trend that we need to continue monitoring.
Mr. Hoyer. Also, one of the things that my friend Joe Early
would have been concerned about was how much good science was
not being funded. In other words, obviously at some level, and
I don't know where that is, at 33 percent or 34 percent, at
some level above that what peer groups are saying, this is
interesting, but probably not worth the investment, but clearly
I am presuming that you think that there is good science not
being funded above 16 percent pay line?
In other words what I am asking you, where could you go and
still feel that we are investing our money well?
Dr. Hodes. Despite the fact that it is difficult to give a
high limit to this number, I think it is rather straightforward
and easy to say that at 17 percent that number is clearly too
low. In the range of recent success rates across NIH of late,
in the 25 percent category, there is great confidence in the
fact that the research being supported is uniformly outstanding
as reviewed by the peer review process.
Mr. Hoyer. Thank you. Dr. Kirschstein.
Dr. Kirschstein. I agree with what Dr. Hodes has said and
we have made sustained and strenuous efforts, and we will
continue to do so to assure that in the cohort of individuals
who receive our competing grants, there will be an appropriate
number, in fact, the number equivalent to that which we have
been supporting and probably higher, of new and young
investors. This is a priority for all of the institutes and for
the NIH as a whole.
Mr. Hoyer. Thank you. Thank you, Mr. Chairman.
Mr. Porter. Thank you, Mr. Hoyer.
Dr. Hodes you are doing a marvelous job and I am sorry more
members were not here because I find your presentation and the
discussion of what you bring to us fascinating. We thank you
for the work that you are doing at NIA.
Dr. Hodes. Thank you all.
Mr. Porter. I remind the subcommittee members that we have
NCRR immediately after this vote and the committee will stand
in recess briefly for the vote.
[Recess.]

NATIONAL INSTITUTE OF MENTAL HEALTH
WITNESSES
STEVEN E. HYMAN, M.D., DEPUTY DIRECTOR
RICHARD K. NAKAMURA, PH.D., DEPUTY DIRECTOR
WILLIAM T. FITZSIMMONS, EXECUTIVE OFFICER
J. RICHARD PINE, BUDGET OFFICER
GEMMA M. WEIBLINGER, SPECIAL ASSISTANT TO THE DIRECTOR
RUTH L. KIRSCHSTEIN, ACTING DIRECTOR, NIH
DENNIS P. WILLIAMS, DEPUTY ASSISTANT SECRETARY, BUDGET, DHHS
Mr. Porter. The Subcommittee will come to order. We
continue our hearings on the budget for the National Institutes
of Health with the National Institute on Mental Health and we
are pleased to welcome Dr. Steven E. Hyman, the Director, who
probably has the most fascinating job of all, and as we have
said many times, your area, mental health, is probably the
frontier that we know least about and need to know the most
about.
So, why do you not introduce the people who are with you,
Dr. Hyman, and then proceed with your statement.
Dr. Hyman. Thank you for that very gracious introduction.
On my far left is Gemma Weiblinger, who is my Special Assistant
and Congressional Liaison; Mr. Richard Pine, our Budget
Officer; Mr. Richard Nakamura, who is Deputy; Mr. William
Fitzsimmons, the Executive Officer, who you have just actually
met; and, of course, Mr. Williams and Dr. Kirschstein.
Mr. Porter, this has been a really wonderful year for the
National Institute of Mental Health on several counts. But it
is not an entirely happy moment for me because I realize that I
will be appearing before you for the last time and I just want
to take a moment to say how important this Subcommittee has
been but also, Mr. Porter, you in particular. I met with you, I
think, my second or third day on the job and one of the things
besides the support of this Committee, I think an important
tone that you have set is that along with the healthy
increases, we needed to be fully accountable and demand
excellence. And it is something that has really helped me to do
my job as well as I am able and I appreciate the support of
this Subcommittee but I also really appreciate the integrity
and the seriousness and the high standards that you have
communicated to all of us and it is much appreciated.
GROWING AWARENESS OF MENTAL DISORDERS
This has been a great year for mental health because based
on the accumulation of scientific evidence, based on the
recognition that mental illnesses are real, diagnosable, and
treatable, based on evidence from the World Health Organization
and World Bank that I actually heard Mr. Hoyer quote in his
questions to Dr. Kirschstein, the Nation has begun to confront
some of the issues that you alluded to in your remarks. There
was a White House conference, for example, on mental health
which was a very healthy way of getting the word out, again,
that these are real, diagnosable and treatable illnesses; it
also was a chance for the National Institute of Mental Health
to work very hard in dissemination activities and every one of
you has a copy of our ``Science On Our Minds Fact Sheets'' that
we produced for the White House conference. They are in a clear
folder. And we are keeping these updated. They are also on the
Web and they are extraordinarily popular. In fact, our updated
Web site (www.nimh.nih.gov), designed for the White House
conference, now gets 5 million hits a month.
In addition, based on this science, there was a first-ever
Surgeon General's Report on Mental Health, which we might
discuss further at length but, again, to have the Surgeon
General, the chief public health officer, making mental health
one of his priorities is really critical for us, again, getting
the word out that these are real, treatable illnesses. In
addition, the Surgeon General issued a Call to Action on
Suicide. In all of these activities the National Institute of
Mental Health was pleased to collaborate along with other
Federal agencies as leads for providing the scientific
background.
NEW APPROACH TO CLINICAL TRIALS
But it was also a great year because of the healthy budget
increases which we have used, I think, to do very exciting new
things. Beginning two years ago and continuing vigorously last
year, we began an entirely new style of clinical trials. You
know, the standard clinical trials for an antidepressant or an
antipsychotic drug were really based on the model that industry
would use to get FDA approval, which is often a six-week trial.
But for an illness like depression or schizophrenia, six weeks
is but a moment in the course of a terrible illness. We
recognized that with the healthy increases we had gotten we had
the opportunity to initiate trials that were more true to life,
that is, where people would be followed in larger numbers for
greater lengths of time, helping us to understand the treatment
of these chronic illnesses.
In addition, what we recognized is that traditional
clinical trials, in order to maximize the ability to see the
effect of a drug, would often exclude lots and lots of people
from the trial: in a depression trial anyone who was not say
between 20 and 60 might be excluded, anyone with heart disease,
anyone who had anxiety symptoms and probably anyone who drinks
alcohol excessively.
Well, in reality, of course, people who come for health
care do not always meet textbook criteria, and we need
information that is truly applicable to real populations in
real health care settings to help both patients and doctors but
also, frankly, to convince insurance companies and employers
that the treatments are relevant and effective. In the last
year we were able to initiate two new trials that more closely
reflect reality: one is on the very important topic of
depression that does not respond to initial treatment.
Depression is very common, affecting 19 million Americans
annually, and about 20 percent of them do not really improve
with our current treatments and we need to know how to treat
this very large number of people. A second trial that we
initiated is on the best use of the new antipsychotic drugs.
ATTENTION DEFICIT DISORDER STUDY
We had the release of long awaited results from a clinical
trial called the Multi-Modal Treatment Assessment Trial for
Attention Deficit Disorder and perhaps there will be questions
about psychopharmacology in children given what has been in the
news in the last few weeks, but this was a very interesting
trial. Again, it took 600 children and followed them for what I
think is really the ethical limit for a randomized clinical
trial, which was 14 months.
You know, you could not really ethically randomize a kid
for 10 years, but it was 14 months and we compared Ritalin, a
very, very rigorous behavioral therapy, the combination of the
two, and ordinary community practice. Ritalin emerged in this
age group, which was above the age of 6, as quite safe and
effective, which is important information for parents. But one
thing was really troubling. The children in the community
treatment comparison group were also on Ritalin, but they did
not do very well at all. And we recognized that the use of
Ritalin or other psychopharmacologic interventions in
children--this should be true of all of medicine--the
effectiveness really depends on the quality of the evaluation
and the interaction with the family. We believe that
prescriptions were being written but side effects were not
being ascertained, adherence to treatment was not being
ascertained, there was not the right explanation and help,
frankly, hand-holding, and, so, there were enormous differences
in outcome that we, again, might come back to later.
[The information follows:]
BASIC RESEARCH ON MENTAL DISORDERS
Dr. Hyman. In basic science--and I will go quickly here in
the interest of time--perhaps some of you have heard--and if
you look at this chart on my left--that for severe depression
we actually begin to see physical changes in the brain (Figure
1). A critical part of the brain, called the hippocampus, a
part of the brain that is required for conscious memory, may
begin to atrophy in depression. This is due to the fact that
about half of people with severe depression elaborate very high
levels of a stress hormone, cortisol, which may be toxic to
neurons. This is an MRI scan from grantees at Yale and what you
can see, outlined in red, is the healthy control on my left and
on the right you can see the person with severe depression--and
outlined in red and blown up at the bottom is this hippocampal
atrophy.
Now, this, of course, is very worrisome, brain damage,
could it be irreversible. And one of the issues, certainly
something I learned as a dogma in neuroscience, is that the
brain does not ever make new neurons. You know, you are born
with your full complement of neurons and every kid on the
school bus says if you bump your head you lose some and so on.
In fact, this dogma has turned out not to be true and it is a
message of hope for conditions like this.
[The information follows:]
Dr. Hyman. If I could have the next poster. A number of
investigators, including an NIMH grantee, Elizabeth Gould, at
Princeton has good evidence for the generation of new
potentially functional nerve cells in the brain, including the
hippocampus (Figure 2). Interestingly, this story started with
the study of song birds. Sometimes people wonder why we study
song birds. Canaries sing a wonderful song in the Spring and
they do pretty poorly in the Fall and it turns out that they
actually grow neurons in the Spring before they relearn their
song and they atrophy in the Fall. Now, this wholesale
development of an organ in the brain is very unusual. But it
gave people the opportunity to begin to study the generation of
new nerve cells in the adult brain.
In rat brain, seen here, the blue is the background, the
hippocampus, in red, is the part of the brain that gets damaged
in depression. Staining for DNA, cells that have made new DNA,
therefore, new cells, there are new neurons being made in the
rat brain. Now, strikingly, if the rats get stressed the amount
of neurogenesis decreases. And this could be because the stress
hormone, cortisol is now up. It might have been what is
attacking the hippocampus in people who are depressed. We do
not know this yet. But--and here is something really
interesting--if you train these rats in a hippocampal-dependent
task, new object learning which uses their hippocampus, the
rate of neurogenesis actually increases. So, it is really
fascinating.
So, we do not know yet whether these neurons are really
incorporated into usable circuits. There is a long way to go. I
do not want to oversell this but it is really exciting. It is
the death of a false scientific dogma. The idea is that this
could be happening in the brain. Fred Gage and colleagues have
actually demonstrated this in human beings, in terminal cancer
patients in Scandinavia, who were getting a DNA marker to
follow their tumor size. When those individuals passed away
their brains were looked at and there was actually new growth
of neurons in humans. So, this is a phenomenon that is exciting
and that will really potentially have an enormous impact on
health. Again, we do not know just how far.
APPLYING BEHAVIORAL SCIENCE TO PUBLIC HEALTH
I just want to touch on two other things that, again, the
healthy increases in budget have allowed us to do. One is the
area of translating basic science rapidly and significantly
into the clinical arena. Now, I have talked to you in the past
about how we have done this in molecular biology and in
pharmacology and it is obvious that this is an important goal
for all of NIH.
One area, however, in which this has been lacking is in
basic behavioral science. In some sense we have not asked that
basic behavioral science be translated into public health
applications. And, so, after a National Advisory Mental Health
Council report, and after a meeting that brought together
psychology department chairs who were often sequestered off in
colleges of arts and sciences and never have dealt with public
health issues, with deans of schools of public health, we have
come up with programs to bring what we know from basic
behavioral science to bear on public health issues. Issues like
treatment adherence. Very important in all fields of medicine,
but in depression we know that the major reason for treatment
failure is people do not go to their psychotherapy, do not take
their medications. Clearly there are important behavioral
advances but we need new ideas and new ideas we believe will
come from bringing together basic behavioral scientists, people
who really understand the underpinnings of human behavior, with
people interested in public health applications.
[The information follows:]
YOUTH SUICIDE
Dr. Hyman. Finally, I want to talk a bit about youth and,
in particular, youth suicide. And I am going to highlight this
because there was a hearing in the Senate which was
highlighting problems with youth suicide. What you see here
(Figure 3) is that the rate of suicide among all youth
increased three-fold from about 4 per 100,000, peaking at about
12 per 100,000 a number of years ago and settling back just a
little bit at really unacceptably high rates. And within this--
and you cannot see this--this suicide rate traditionally was
really contributed to almost entirely by young Caucasian males.
However, in the last few years, the rate of suicide among
minority youth has climbed markedly. The rate of suicide among
adolescent African American males doubled between 1980 and
1996. In some Native American groups and Alaska Natives the
rate for young males is a staggering 62 per 100,000. I had the
opportunity to visit Native Alaska villages last summer and to
see firsthand some of the problems.
In order to to gain information about what exactly is
happening, we have funded two studies. One is a very large-
scale epidemiologic study that is going to survey kids as young
as the age of 13, really looking at mental health issues across
the entire population but we are really going down into the
young ages because we do not know what the correlation is in
children between depression, other mental illnesses and
suicide, as well as we know it in adults. But more to the
point, we really do not understand what is happening in
minority youth. And as part of this effort, which is being
directed by Dr. Ron Kessler, at Harvard University, Dr. James
Jackson, at the University of Michigan, is initiating a very
large-scale study of the epidemiology of mental disorders in
African American youth. We have been trying to organize similar
studies to deal with problems in different Hispanic subgroups
and in Native Americans. But we need this data to understand
these suicide rates and the disparities among minority groups.
That is a lot and I could go on but I think it would be
best if I stopped here and I would be pleased to answer any
questions.
[The written statement of Dr. Hyman follows:]
YOUTH VIOLENCE
Mr. Porter. Thank you, Dr. Hyman.
I remember that the canary study was one that was
disparaged by an NGO in Washington and then featured on ``Prime
Time.'' It was, Sam Donaldson saying, wait a minute, there is
something very valuable going to come out of this and, of
course, it has.
I want to start with a question that is on so many of our
minds and that is how in the world a 6-year-old in a class in
Michigan could come to school and shoot a classmate dead? We
can say, well, this is something that is just a total
aberration and dismiss it and say, obviously, it has no meaning
but it seems to me that it does have meaning and that this is
the first time it has happened at this age. I wonder if you
could give us your insights on this specific incident and what
kind of--what are we doing to address this problem and head-off
these kinds of horrible incidents?
Dr. Hyman. We are clearly not doing enough to head these
things off. But, in fact, this does have meaning. It reflects
very clearly on some data that may sound like common sense but
is very, very well established and that data has to do with the
role of families and family supervision. In the case where
families are disrupted, data from a large study in Chicago
being conducted by Dr. Felton Earls, suggest that neighborhoods
can also play a role and that is in the appropriate supervision
of children.
Now, of course, we would assume that at the age of 6 a
child would be very well supervised by a family but, clearly,
in this case from what I understand--and I only know the news
reports--this was a child who was growing up in very, very
chaotic circumstances. But the bottom line is that in many of
these tragic instances--and I am not saying it is easy for
parents to know what is going on with their children--parents
have not known what is going on with their children. In terms
of prevention, and again, this is not generalizable necessarily
to a 6-year-old, we know some really clear facts. Much of youth
violence, in fact, the vast preponderance does not occur during
school hours; it occurs between the hours of 3 and 10 in the
afternoon and a lot of it would be stopped if there were
appropriate supervision of youth with either school-based or
family-based or church-based or any other sorts of programs.
Secondly, we know there is a critical aspect to that
supervision and that is that the aggregation of, let us call
them deviant youth, is the final common pathway toward often
criminal careers and violence.
Parents really should not only supervise their kids but it
is very important to know who their friends are. Peers have
enormous power. And, indeed, it is not only parents.
You know, as a society we tend to aggregate deviant youth
in group detentions, group homes, in alternative schools and
there are alternative models that we are funding. Models for
kids who have already been in bad trouble include therapeutic
foster care, for example, where the foster families are taught
and supported. There is a 24-hour, on-call person. It is a lot
cheaper than incarceration, even though it is labor-intensive.
One of the key things that the parents learn is the need for
supervising kids and the need for keeping them apart from, you
know, bad friends. Again, it sounds like common sense, but we
are not doing it and a lot of the way we are treating kids is
to aggregate kids, creating, in essence, ``graduate schools for
delinquency.''
To return this discussion to this 6-year-old, it is clear
in retrospect and tragic to have to say that this was not an
appropriately supervised child. Whether this child had a
serious emotional disturbance that could have been diagnosed
and intervened with is anyone's guess. But what I will say is
that one of the lessons we have learned from some of the
horrific school violence is that disorders that we have not
previously associated with violence, disorders like depression
and anxiety actually may contribute to violence. Some of the
anxiety disorders might actually come from exposure, witnessing
violence. It turns out that a combination of depression and
conduct problems is a really combustible mix because these
depressed kids are sullen and withdrawn and often irritable and
we do a very bad job of identifying these kids in school
settings. You know, the sullen, withdrawn kid is sometimes
mistakenly considered a good kid. They are not out of their
chair, racing around like the kid with attention deficit
disorder. And we really need to do a better job of identifying
these kids and treating them.
STRESS AND MENTAL HEALTH
Mr. Porter. Dr. Hyman, you mentioned a stress hormone, I
think you called it cortisol?
Dr. Hyman. Hmm-hmm.
Mr. Porter. You said it was a stress hormone, so I assume
there are many.
Dr. Hyman. Yes, there are.
Mr. Porter. There is a good body of information that leads
us to believe that stress has a great role in health,
generally, and one assumes also in mental health. Are there
studies underway in your Institute or elsewhere to figure a way
of preventing the hormone from doing its damage? In other
words, we know that we all are going to be stressed throughout
our lives, but is there a way of perhaps controlling the
damage?
Dr. Hyman. Yes. It is a very interesting and important
question and it is an enormous area of research. So, first of
all, these stress hormones, like cortisol, adrenaline, we have
them because we need them in emergencies. You know, when our
ancestors were faced with a saber-toothed cat, their body
needed to be prepared, right? You need to get the blood away
from where it was digesting lunch and into your thigh muscles
so you can run. You need to do things to your brain. You have
to stop mulling your prehistoric philosophy and start being
vigilant and scanning and really alert. You, interestingly,
have to suppress pain responses. You know, if you are running
from this animal and you cut yourself it is not the time to be
saying, ouch, you have got to keep going. You actually know
this from ordinary life. You might be involved in a heated
tennis match and you hurt yourself and you do not realize it
until you cool down afterwards. And that is sort of a relic of
our ancestors' response. You suppress your immune system. You
know, you better not get a swollen knee at this minute, that is
for later, that is for splinting the knee after you have
finished the tennis match. So, your immune system is
suppressed. Also, you need to produce energy. So, you are
melting away fat and turning it into glucose and melting away
lots of other things.
Well, this is great in an emergency. The problem, of
course, is if this system is activated chronically for no
reason. We see this in people with major depression, we see
this in people with post traumatic stress disorder, and we see
this actually in some youth. It is very interesting, there were
abnormal levels of this hormone, cortisol, in some of the
Rumanian orphans who were brought to the United States and
studied and found probably just ordinary interpersonal
interactions very stressful.
So, we are studying the biology of this to mitigate some of
the damage, to understand how this process is controlled. Just
to take one example: There is actually a medication that is
going to enter clinical trials that blocks the machinery,
upstream of cortisol release. It is another hormone called
corticotropin releasing hormone, and it blocks the functioning
of that master switch. The real question is whether it is going
to do too good a job? You know, again, we need these stress
hormones. We have lots of stressors--we do not meet saber-
toothed cats any more, but we get a viral infection, our body
does have to mount a stress response.
So, the hope is that we are going to find interventions, in
this case a medical intervention but also potentially psycho-
social and behavioral interventions, that can get this stress
response back to where it ought to be; that is responding
briefly and acutely to real stresses, but not flooding our
bodies chronically with these hormones, because you do not want
your immune suppressed over the long-term and so on and so on.
Mr. Porter. Thank you, Dr. Hyman.
Mr. Hoyer.
TRENDS IN YOUTH SUICIDE
Mr. Hoyer. Thank you, Mr. Chairman.
Doctor, I have some questions but let me make an
observation about your response to the question. Initially you
said the child did not have proper supervision. I think that is
such an understatement as to really almost not be accurate.
Dr. Hyman. Yes. I agree.
Mr. Hoyer. There was a story in the ``Washington Post'' 10
years ago about a child named Doonie Waters, who lived in
Prince George's County. He was 6 years of age and he lived in a
crack house. He had no bed, the bathroom was not working, his
bedroom was used to shoot up by his, presumably his mother,
very similar situation. Doonie Waters did not commit a crime
but Doonie Waters was left in that context for way too long a
period of time.
In 1978, we adopted legislation that had the premise that
we needed to keep children with their parents. That was the
primary objective of the system. It had a good premise, that
children with their families that properly supervised them are
better off than they are not. The tragedy is that not only did
the suicide rate go up and I want to ask you about this 1968-
to-1978 spike----
Dr. Hyman. Yes.
Mr. Hoyer [continuing]. Because I look at your--there was
a----
Dr. Hyman. Enormous.
Mr. Hoyer [continuing]. It is interesting the spike is not
recently, the spike was 1968 to 1978, where it doubled from 4
to 8.
Dr. Hyman. That is correct.
SOCIETAL ROLE MODELS FOR YOUTH VIOLENCE
Mr. Hoyer. One of the things that I think in the context of
you and Dr. Alexander and others, this child had no family.
This child had a learning experience which was filled with
violence. Every child in America, of course, has the
opportunity to turn on the television and watch Jerry Springer
that dramatizes and puts before us some of the most
dysfunctional human beings in our society. The Worldwide
Wrestling Federation puts on television activity that is not
conscionable by a civilized society. The National Hockey League
allows people to hit people with sticks and only in the most
egregious events do we respond as we responded just recently.
There ought to be criminal prosecution of somebody that hits
somebody with a stick, I do not care what the game is. So, I
mean it is something that we ought to be motivated as a
society, we teach all of our children violence.
Mr. Porter. Will the gentleman yield on that?
Mr. Hoyer. Yes, sir, I would be glad to yield.
Mr. Porter. You might be interested to know that in my
district the grandson of my finance chairman was recently in a
high school hockey game, and was hit from behind after the game
was over, allegedly. He is paralyzed from the neck down, he is
15 years old, and the State's Attorney of Lake County is
prosecuting the individual who did it as a criminal act.
Mr. Hoyer. Mr. Chairman, I am glad to hear that. Frankly,
Abe Pollin is a good friend of mine and I have had discussions
with him for the last 20 years about the countenancing of
fighting in hockey. You know, they do not do that in the NFL.
The National Football League, are there fights? Yes. It is a
sport and they hit one another and people get mad and they take
a strike. But they are ejected and they are separated
immediately. You know, people do not stand around and watch and
say, you know, the Christians are being fed to the lions, which
is essentially what we have.
So, Doctor, it seems to me that this is a systemic, broad-
based problem. Jerry Springer outrages me. We ought to,
frankly, boycott every advertiser of the Jerry Springer show
because what he is doing--and that is on at 4 o'clock in the
afternoon. It is despicable that a civilized society would
countenance that.
He was going to run for the United States Senate and my
party, I think luckily, was outraged by it and he did not run.
But I mean, you know, the concept that somebody like this would
be--so, I was--your answer was very mild in terms of my
reaction as to why this 6-year-old child, why society did not
rip him out of this context.
I mean if he went to kindergarten, they had to have some
knowledge of what was going on. A child does not live in a
crack house with no bedroom of his own, probably no sanitary
facilities available to him, nobody fixing him breakfast, lunch
or dinner without the system knowing that we have got to save
this child and bring him out and the consequences are not only
that we lost this child, maybe the next child can be saved, but
we lost another totally innocent child.
Dr. Hyman. The tragedy is that one story gets in the
newspaper but this is replicated infinitely across the country.
Mr. Hoyer. And, again, in 1978 our theory was because we
thought about families being functional and if families are
functional, absolutely the children ought to be with them.
Dr. Hyman. Right.
Mr. Hoyer. But to leave a child in this context for very
long is a national disgrace. And it happens in my county. This,
you know, obviously, it was not in my jurisdiction but it
happens in my jurisdiction and every jurisdiction in America.
We need to raise that issue.
Let me ask you some questions about the budget. Where do
you stand relative to other institutes in the rate of grants
submitted and approved?
RESEARCH GRANT SUCCESS RATES
Dr. Hyman. Since my arrival three years ago, we have had a
very healthy increase in the number of grants submitted. We
have, in terms of historical success rates, been rather on the
low side with a success rate in the last year of, I think,
about 26 percent. You know, for me one of the things that has
done my heart good as the director of this institute is that we
have had an increase in very high quality applications. Before
I arrived, as you remember, of course, NIMH was part of ADAMHA,
and when NIMH rejoined NIH in 1992, one of the goals was to
join the review of NIMH grants with the rest of NIH.
Fortunately my colleague at the Neurology Institute at that
time, Zack Hall, agreed with me that the best way to integrate
neuroscience review--and, subsequently, we have done this for
behavioral review at NIH--was to start with a blank sheet of
paper. You know, the study sections were 20 years old, the
science had changed, and we started with a blank sheet of
paper, we involved the extramural community and we came up with
a whole new set of review sections. In those review sections,
grant applications referred to NIMH are doing somewhat better
than would be expected against the rest of the league. So, I am
very happy in the quality of grants. I, obviously, wish I could
do better, given that quality, than a success rate of 26
percent.
Mr. Hoyer. How much good science do you think we leave on
the table? I asked this question last time and I think Dr.
Fauci answered in the neighborhood of 45 percent, which meant
about half of the good science or a little more than half,
probably 60 percent of the good science was funded.
Do you think that is about right?
Dr. Hyman. I think Dr. Fauci is about right. I would tell
you that not being able to pay a success rate of 35 percent
is--I mean if you look at the next 10 percent there is a lot of
really good science there.
USE OF RESEARCH BUDGET INCREASE
Mr. Hoyer. Now, the other related question is--and you have
indicated in your statement that you have been able to expand
some translational research----
Dr. Hyman. Translational research in clinical trials.
Mr. Hoyer [continuing]. You indicated in your statement you
have been able to coordinate better and expand that. You have
gotten generous increases. Are you confident that we are
expending that money effectively and efficiently and can absorb
it at the rate that it has been increased?
Dr. Hyman. In NIMH I am absolutely confident and I am
confident for several reasons. First, the brain sciences are
maturing now at an astounding rate and we now have tools for
really incisive and good investigations. Things like neuro-
imaging, things like you saw on the neurogenesis slide, are
generating an enormous amount of good science.
The second thing is--and I am actually quite proud of this
as an accomplishment for the institute--I think that we were
sort of at the leading edge of the recognition that many of the
most common human illnesses and, indeed, the risk of all mental
disorders is genetically complex. That means that more than one
gene, plus non-genetic factors, all conspire to produce risk,
not a single gene, as is the case for Huntington's disease. And
by using, I think, some of the very best geneticists in the
United States to help us think about how we would solve these
problems, we have actually attracted people into our portfolio:
People who had never had NIMH grants before. And that has been
something that has really been something I have tried to do to
get really the best possible scientists to get interested in
our problems and that is becoming successful.
So, I think that is another hallmark of good science. And
then the clinical trials I described at the outset I feel are
high-risk. You know, when you break out of the usual safe mold
and you start doing trials that look at real people and real
settings, the danger is that they will lose some rigor. Of
course, the danger of having a rigorous trial that is
irrelevant is that you have answered a question that nobody
cares about. So, I think that is going to be very important
science. But I think only in the context of the support that
you have given us can we do good science that also breaks the
mold, you know, where there is risk, where we are going to
start to answer some important questions.
Mr. Hoyer. Thank you very much.
RISK FACTORS FOR YOUTH SUICIDE
I know my time is up, Mr. Chairman, but I would like to at
some point in time pursue why the 1968-to-1978 period was such
a spike because that would be very relevant--suicide is a
critical problem, obviously, in our community. I do not know
whether you want to let him answer that. But I think it is a
relevant question.
Mr. Porter. I think you snuck it in. [Laughter.]
Dr. Hyman. Let me just say about----
Mr. Hoyer. Thank you for your tolerance of letting me do
so.
Dr. Hyman. Let me say something about suicide, which I
think the American people do not realize. There were 31,000
suicides in the United States in the last year, I think 1998,
for which we have good statistics. There were in contrast,
19,000 homicides. So, people tend to read the newspapers and
think that homicide is the leading cause of unnatural death. It
is actually suicide by a long shot.
This is an enormous public health problem. It is the 9th
leading cause of death overall, for young women the second
leading cause of death and for young men the third leading
cause of death. And, of course, it leaves unutterable tragedy
for families.
We believe that this spike had to do with a number of
things but a critical factor had to do with drugs. And we
believe that the rise in African American youth also had to do
with the rise of drugs. Drugs seem to be a lethal co-factor
when mixed with a child who has depression. I mean drugs often
push them over the top.
There are other theories but one of the reasons we want to
do this careful epidemiologic study is we really do want to
understand these risk factors in more detail.
Mr. Hoyer. Thank you, Mr. Chairman.
Mr. Porter. Thank you, Mr. Hoyer.
Mr. Miller.
USE OF PSYCHOACTIVE MEDICATIONS IN CHILDREN
Mr. Miller. Good morning.
First off, there is something that you made a comment about
in your statement and it has been discussed for children and
all of that and it has been in the lay literature about the use
of the Prozac and things like that.
Dr. Hyman. Yes, yes.
Mr. Miller. You know, what we are hearing, you know, what
is your concern about that issue? Just, you know, the over-
medication. Does it lead to violence?
Dr. Hyman. Yes, yes. Well, okay. So, there are a few
things, Mr. Miller. It is a really important question. I would
answer that the real problem is inadequate knowledge and it is
not so much over-medication as over-medication and under-
medication. The wrong kids are often getting these medications.
Now, what do I mean by that?
First of all, there has been a dearth of studies in anybody
under the age of 18 for psychopharmacology and, frankly, for
psychotherapy as well. One of my enormous frustrations as NIMH
Director is the lack of a research infrastructure to deal with
children's problems and we have been working on that with
career awards to welcome pediatricians into the field,
neurologists, any good scientist who wants to come into this
field, we will pay for their retraining and the initiation of
their research.
We have also, for the first time, brought the pediatricians
on board as a critical group because they are the ones who are
really seeing these kids. It is not the psychiatrist. We have
data that for kids above the age of 6, as I was describing,
Ritalin is safe and effective. But let me focus on this for a
minute. What we recognize is that about 3 to 5 percent of
children have attention deficit disorder and that, untreated,
the outcome is bad. These kids, they cannot learn in school so
they do not live up to their potential. They have a higher risk
of eventually using drugs, and here is an anecdote: The number
of kids with untreated attention deficit are so over-
represented in incarcerated populations that the Justice
Department, the Office of Juvenile Justice, co-funds some of
our ADHD treatment studies. So, I think that is testimony to
how badly these kids do untreated.
But here is the problem. In some neighborhoods, especially
Caucasian, upper-middle-class neighborhoods 20, 30 even 40
percent of the boys may be on Ritalin and this is a disorder
that occurs in 3 to 5 percent of children. In contrast,
actually in many inner-city neighborhoods there is no Ritalin
used because the word is out on the street that this is a
chemical restraint to, you know, to take away normal boyhood
and a tool of discrimination. So, the problem is that there are
lots of kids getting Ritalin who really do not need it and
there are other kids who need it who are not getting it. And,
you know, it is true that even for a kid who would not meet
diagnostic criteria for attention deficit disorder, Ritalin
will help them concentrate better, it will make them somewhat
easier to teach and parent, but I would argue that there ought
to be other behavioral means and we ought to reserve the
medication because even though the safety record of Ritalin is
much better than the media would lead you to think, any
medication has side effects and raises concerns. You just do
not want to be reaching for the pill instead of engaging in the
kind of behavioral interactions that would be appropriate.
Now, we know less about antidepressants in children. In
fact, we know virtually nothing about SSRI's, Prozac-like
antidepressants in children below the age of 12. We know very
little about their use in teenagers. One of the things we were
able to initiate, actually two years ago was one of these
clinical trials that I was describing to Mr. Porter and Mr.
Hoyer on adolescent depression, looking at Prozac,
psychotherapy and the combination. We do not actually have
enough researchers yet who could conduct such a trial in
children under the age of 12. So, it is really very much
needed.
Mr. Miller. But how much is it being utilized right now?
Dr. Hyman. A lot. But we believe that perhaps as many as 5
percent of children under the age of 12 get an antidepressant
at some point. Now, the most troubling thing to me was this
recent finding of the use of two types of drugs, clonidine and
tricyclic antidepressants, in preschoolers, age 2 to 4. This
was in the media and on television.
I have a particular problem with the use of the drug,
clonidine and with tricyclic antidepressants in these very
young children because these are drugs that actually have known
side effects, including very rare cases of sudden death.
Clonidine is being used probably to sedate kids who are really
acting up a great deal.
The tricyclics may actually be being used for bedwetting.
You know, at low doses they are very useful for treating
enuresis, or bedwetting. But, you know, I am a parent of a
young kid. If a 2- or a 3-year-old is not ready to be toilet
trained what is wrong with a diaper and a little behavioral
therapy? I mean I would not be giving a kid a tricyclic
antidepressant. And insofar as their being used for depression
it is really an irrational practice because unlike the Prozac-
like drugs, these have been studied in young children and zero
of 13 studies found efficacy.
So, again, we do not know enough but what we know is not
being appropriately applied and we really are going to need to
somehow get the word out, you see, not to psychiatrists but to
family doctors and to pediatricians.
DISSEMINATE BEST PRACTICE INFORMATION
Mr. Miller. What is being done to get that word out? I mean
obviously----
Dr. Hyman. Well, we have been trying to actually engage the
pediatric community in NIMH research. We are also trying to
disseminate, again, you know, it is late, I admit, but in the
context of these news reports, we have put together a fact
sheet to disseminate on what is known and what the best
practices are for primary care providers. We also have been in
contact with the FDA about having a conference about what we
can do in terms of really getting the word out appropriately.
Mr. Miller. What other ways are there to get the word out
besides your institute? FDA?
Dr. Hyman. Child Health. Well, I think that the
professional societies could have an enormous role.
Mr. Miller. With all of this publicity.
Dr. Hyman. We have had some--yes, actually ``U.S. News''
and ``Newsweek'' have helped disseminate this. And actually
were very responsible articles.
Mr. Miller. Were they good articles?
Dr. Hyman. Yes. The ``U.S. News'' article----
Mr. Miller. Good. I have got it sitting on my desk.
Dr. Hyman. Yes, yes.
TRANSCRANIAL MAGNETIC STIMULATION
Mr. Miller. Let me ask a couple of quick questions before
my time is up. In January I was up at the University of Florida
and went to the Brain Institute and I was really impressed with
these magnets, you know, these gigantic ones that they have
there.
Dr. Hyman. Yes.
Mr. Miller. The possibilities there--I mean the really
powerful ones are not designed for humans yet.
Dr. Hyman. Yes.
Mr. Miller. But the ability, what they are talking about
doing is exciting. I mean do you--I know you do some funding
through there.
Dr. Hyman. Yes, yes, a lot.
Mr. Miller. But the potential for that whole magnetic
imaging, you know, because you can really target exactly what
you want in the brain without playing around.
Dr. Hyman. Well, we have created a new psychiatric syndrome
which is ``Tesla envy'' because you measure the strength of
these magnets in Tesla and, you know, you can attract
scientists depending on how big your magnet is. [Laughter.]
NEW BRAIN IMAGING TECHNOLOGIES
The potential is enormous. Let me just give you one example
of something that I have been really trying to facilitate, both
within our intramural program and also extramurally to a number
of sites. High field strength functional magnetic resonance
imaging is going to give us the ability to really see with
incredible spatial resolution the activity of the brain as it
thinks, as it feels, as it performs motor acts.
But one of the things about the limitation of this
wonderful technique is that it collects data no more quickly
than one second. Because what it is seeing is not the neurons
firing, but when neurons fire or work they call for more blood
and more oxygen. You know, they are busy. And what we actually
can see in the magnet is the change in blood oxygenation;
whether hemoglobin has oxygen on it or not, slightly changes
its magnetic properties. But it takes about a second for that
blood flow to arrive.
There is another technology, however, called
magnetoencephalography, or MEG. Neurons are electrical and
every time you have an electric current you generate a tiny
magnetic field. MEG devices are super-conducting devices that
can detect the minute endogenous magnetic fields produced by
human neurons. And they work on the millisecond time scale that
the neurons are actually working on because they are detecting
the results of the actual electrical change in the neurons.
What we are trying to do computationally is put together
FMRI, for its great spatial resolution, and MEG, for its great
temporal resolution, and we are starting to see, obviously
slowed down for us, real time movies of neural activity
following cognition and emotion. And we are just at the
beginning. I think we are going to have an incredible window on
the brain which is obviously going to be very relevant to
making diagnoses and developing new treatments for mental
illness.
Mr. Miller. Thank you.
Thank you, Mr. Chairman.
Mr. Porter. Thank you, Mr. Miller.
Mrs. Northup.
RITALIN AND HYPERACTIVITY
Mrs. Northup. Thank you, Mr. Chairman.
First of all, I would like to go back the question about
Ritalin and hyperactivty. I realize attention deficit disorder
is not the same thing as being hyperactive but they often are
assiciated.
Dr. Hyman. Yes, that is correct.
Mrs. Northup. Children that have attention deficit are
often hyperactive. And, you know, as somebody that had that as
a child and can remember in great detail that I could not sit
in my seat in school. I learned through really wonderful
parents, who helped me see this as a positive. Probably my
husband thought it was great to marry somebody with so much
energy but when we started having 2 year olds with this much
energy it was not quite so much fun.
Dr. Hyman. Right. [Laughter.]
Mrs. Northup. And I was so determined I would not use
Ritalin, no sugar, no artificial flavorings and colorings. You
know, I did it all. Until finally, you know, when the oldest
was 7 the doctor said you really ought to try Ritalin for your
child. I think it is the most wonderful drug. It is the most
amazing drug and I agree with you that learning the skills are
so important too--time management, being organized, running--so
that you can use it effectively.
But what I am getting to is that I really raised my
children with them thinking they were really the most lucky
kids in the world and that is how I feel about myself. Because
I do have more energy than anybody I know and over the years of
working to stay focused, to be organized, to overcome maybe a
natural sense of time and so forth, it has been probably the
luckiest thing I have. It really bothers me to constantly see
this being talked as like a mental illness and my children say
the same thing, how much they got out of it. I would tell you
that in our family of 6 kids the couple that are hyperactive
are looked as the luckiest of our children. They could train
longer in sports, they had to build up the other capabilities
that went with it. But when you see 5 million kids in your
statistics that had ADHD last year and you say 3 to 5 percent
of the kids in this country have it, then we are under-
diagnosing by a lot.
And I wonder if some of that is because of the negative
connotations. I struggle with this because I have a right to
disclose who I am; my children do not necessarily want their
mother disclosing who they are. And yet, recently a talk show
host immediately equated it to schizophrenia drugs and
depression, and I thought--oh, boy, I am really sorry that this
is the message going to parents who have a child they are
considering Ritalin.
``Mental Illness'' STIGMATIZES
Dr. Hyman. Well, your comments are really right on target.
The term mental illness, which we have inherited, is just
completely wrong. We are talking about brain conditions. If I
could get another word besides mental illness it would do a lot
of people an awful lot of good. It is a holdover from ancient
times and bad theories.
TREATMENT OF ADHD
In fact, attention deficit with or without hyperactivity,
may have been useful 300 years ago when a person was out
hunting to survive; then, you would have been a ``healthy
person,'' and it is only in a modern school setting that it
becomes a disease. So, maybe it is better to think about these
things as brain conditions and what you are really trying to do
is help someone achieve their full and healthy potential with
the benefits of modern medicine.
I do not think that we disagree at all about the use of
Ritalin. There are a lot of people out there, frankly, who have
decided without data that these drugs have got to be bad and
are scaring lots of parents. This occurs in general more in
inner-cities than in suburban communities but it is a general
problem. My feeling is that again that lots of kids who need
it, and I think this was your point, are not getting it, but
that some of the kids who are getting it may not need it.
I think what we really need to do is to improve our
practices and, of course, in this era of trying to hold down
medical costs what is happening is exactly the opposite.
Instead of really evaluating kids right, trying them on the
medication, seeing if it does the right thing for them, helping
the family understand side effects, giving them these other
behavioral aspects, the time management, the other things they
need, what we are getting is often slapdash prescription
writing and that is not helping even the kids who would
benefit.
Mrs. Northup. Right. Let me--do I have time for one more
question, Mr. Chairman?
Mr. Porter. Yes.
ENGAGING YOUNG PEOPLE IN MENTAL HEALTH TREATMENT
Mrs. Northup. It seems to me like, a lot of parents, a lot
of moms and dads that are my age, in their 50s, have children,
young adults. A recurring problem with mental health for their
children when they have children is engaging them, just exactly
as you said, in taking their medicine and going to their
appointments.
Dr. Hyman. Right.
Mrs. Northup. And one of the concerns I have about it,
every time we talk about parity for coverage, is that the
children or the 20-year olds or whatever, there is no amount of
coverage that helps if that child does not feel a sense of
being engaged in it.
Dr. Hyman. Right.
Mrs. Northup. And you hear one parent after another talk
about the breakthroughs. I think of this friend of mine who
said, one day my child said to me, ``You know, you need to get
my prescription renewed; The child said I realized I was on the
phone screaming at all my friends. And I went, hey, it is not
my friends, it is me.''
And that is when the child took seriously--I need to get my
medicine, and I need to go see the therapist. But until then,
the child missed appointments regularly, did not take their
medicine, despite the fact that insurance covered it. And I
guess I feel like there has to be some sort of engagement or
feeling that there must be a limit. And I just wonder if you
would address that question of parity and that sense of
entitlement compared to the importance of being engaged in the
therapy and the medicine.
TREATMENT ADHERENCE RESEARCH
Dr. Hyman. Well, what you have struck upon, of course, is
an issue that is true across all age spans, most difficult for
adolescents, true for all diseases. As you know, adolescent
diabetics also do not want to be different from other children
and have problems with adherence.
But this gets back to your first discussion because the
word, mental illness, is highly stigmatizing. I mean, again,
what we want to say is that these kids have real conditions of
a real organ, the brain, just like any other condition and they
deserve treatment.
Having said that, if we can get over this barrier I think
addressing engagement or adherence is really critical. And we
have begun, as I said in my opening remarks, really to work
with the behavioral science community on this and you know,
this is not a trivial problem. We can have all of these
wonderful fruits of molecular medicine but if the pills stay in
the bottle no one is doing any good and also all of the common
sense things have been tried. You know, the finger wagging,
take your pills. I mean we know this does not work.
I think it is really critical to begin to think about peer
level interventions, family level interventions, school level
interventions, really think outside the box, as to how we can
destigmatize these disorders and get kids really engaged in
their treatment for you are right--whether or not someone is
insured is not going to make the difference.
Mrs. Northup. What about the patches that deliver the
medicine----
Dr. Hyman. Well, those----
Mrs. Northup [continuing]. Regularly. I am not so sure that
some of the cases that my friend, I am not so sure that the
child is rebelling as much as they start to get a little bit
better and it does not become important to them.
COMPREHENSIVE TREATMENT APPROACHES
Dr. Hyman. Yes. Or they want to feel like the rest of their
peers. They do not want to be waking up every morning and
taking a pill or reminding themselves that it is different.
Yes, some of the drug companies are working on other ways of
delivery, like patches, but also psychotherapy and skill
building is important.
And I think we can do a lot better job. You know, a kid
arrives for cognitive behavioral therapy. You know, it is
boring. You know, do your cognitive therapy homework. We should
build-in modules for engaging children. I mean we have to--our
behavioral science community I think can contribute real
improvements in these areas.
Mrs. Northup. Thank you.
Thank you, Mr. Chairman.
Mr. Porter. Thank you, Mrs. Northup.
Mr. Jackson.
Mr. Jackson. Thank you, Mr. Chairman.
Thank you, Dr. Hyman, for being here today.
PARENTAL INVOLVEMENT
I find this conversation to be absolutely fascinating. My
experience is just the opposite of Mrs. Northup's. When I was
growing up my parents wanted to put me on all kinds of drugs
because I was a little anxious but my parents made the
objective decision that what Jesse, Jr., fundamentally needed
was somebody to spend more time with him. So, my mother gave up
her career to spend a little more time with the children and
she kind of followed me to and from school and she was very
available whenever I would beat somebody up or bite somebody
or----
[Laughter.]
Mr. Jackson. She was very available to come because she had
this child who had all this anxiety.
Dr. Hyman. Right, right.
Mr. Jackson. So, I am kind of grateful today that my
parents did not put me on any form of medication. And, you
know, the truth of the matter is, at least from my perspective,
that not all children who are expressing a certain level of
anxiety necessarily need medication. I think that oftentimes we
use medication and mental illness and mental disorders, as we
choose to refer to them, to calm our kids down. In other words,
to get our children to fit into our schedules on the terms that
we want our children to relate to us, rather than being anxious
when our children are anxious, and excited when our children
are excited, and want to go out. We want them to calm down
because we are tired, so, take your medication. All too often
this is an excuse for not being a better parent.
And if I had to speak today on this Committee on behalf of
young people across the country who are being forced to down
all kinds of drugs because they will not calm down, I think
that NIH needs to spend some time developing a better parent
drug. [Laughter.]
And parents ought to start taking some drugs that calm them
down and prepare them for parenthood, including taking their
children to and from school, spending time with their children,
making some adjustments around their careers and around their
portfolios so they can raise the babies that they make. That is
my own earnest opinion.
RESEARCH ON ``BAD BEHAVIOR''
But suffice it to say we are not here to discuss that, even
though it is a significant part of what you do. One Committee
in this Congress, the Committee on the Judiciary, allows
certain behavioral disorders to be sufficient pleas or
justification for the criminal defendant. I am sure you are
very well aware of many of them. And I would imagine that the
use of these behavioral disorders for the criminal defendant
come in various forms. Pleas for insanity, temporary insanity,
all suggesting some mental disorder. Someone always pointing
back to their childhood or pointing back to some significant
event in their life that led to their present contemporary
behavior, which the other Committee seems to refer to as
criminal but tends to manifest itself in some significant
behavioral or mental disorder.
I was just wondering if, since the National Institute is
charged with studying mental health, if whether or not the
byproduct, for example, of being sexist, that one might
consider the study of it a significant behavioral disorder,
including the criminal conduct that might result: Beating one's
wife, discrimination on the job, firing someone because they
reject a sexual advance? I am just wondering if sexism and the
study of it, particularly on the male brain, is significant
enough to be categorized as a behavioral disorder?
DEFINING THE BOUNDARIES OF MENTAL DISORDERS
Dr. Hyman. I have philosophically tried to narrow the
medicalization, not to overmedicalize the diversity of human
behaviors for a number of reasons. First of all, we have really
little evidence that any of these things like sexism or racism,
as repugnant as they are, represent a medical condition with
some underlying, perhaps genetic, predisposition.
And I think, insofar as we begin to medicalize these
things, as you imply, you begin to give people exculpatory
stories. And, indeed, in mental health there is a gray zone.
Things are sometimes funny. Schizophrenia, there is no doubt,
it is never normal to be having hallucinations. But when does a
little bit of pervasive blueness, and low energy and excessive
guilt shade over into depressive illness? We have to handle
that gray zone. But I think we err if we begin to take every
negative attitude and social ill and begin to medicalize it.
I also sometimes think about what would have happened to
some of the opposites in other regimes in the world. Perhaps
you recall that in the Soviet Union, people who were dissenters
against the political system were labeled as being mentally
ill, and there was an abuse of psychiatry. So I think it is
very important that we do not medicalize all social problems,
and that we never medicalize evil. We must recognize that when
people have a real mental illness that sometimes, as in the
case of schizophrenia or being in the throes of a manic
episode, you really cannot tell right from wrong. And then, of
course, we do have the insanity defense.
But for many other people the disorders do not usurp their
entire brain. They must remain engageable. We were talking
about----
Mr. Jackson. Dr. Hyman, not the medicalization of the
concept for the purposes of exculpatory for the defendant's
purposes, but for the purpose of the society better
understanding the nature of the problem.
RESEARCH ON STEREOTYPING AND DISCRIMINATION
Dr. Hyman. So we actually do, in our basic behavioral
science portfolio, we actually support social psychology. And
one of the areas that is supported is the study of stereotyping
and discrimination. And we have developed a great deal of
knowledge about the ways in which people create stereotypes and
the impact of those, and those--that research, tragically, I
think has had a greater impact on Madison Avenue than it has
had on the health professions. But the research is being done.
I think it is very important. I would add that it is also
applicable to mental illness because people with mental
illnesses are also stereotyped and discriminated against.
Mr. Jackson. I know this case because I have been trying
to, during the course of my inquiry, trying to find out more
numbers on the number of minority researchers at NIH. And every
time I try and cross-examine or examine the NIH on the question
of these researchers, somehow there is the stereotypical stuff
about substandard research seems to be associated with,
whenever I am asking where are minorities or where are women or
where are Asians, somehow I just end up in a kind of mental
disorder on the question of whether or not blacks with Ph.D.s
and M.D.s are qualified and why they are not pursuing research
at the advanced level at NIH.
But I want to pursue one last question. I think my time is
just about expired. I think it is very difficult, on the one
hand, when we say that insanity is a sufficient defense on the
judiciary side of the equation, but almost all of the insanity
defenses that we have heard, particularly the very public
cases, where the use of insanity became a factor, that there
was some ``ism'' associated with it. O.J.'s view of women was a
factor in O.J.'s case. The Susan Smith case in South Carolina,
the first thing she said was an African American had done it,
and then she claimed insanity on her own basis. The James Byrd
situation in Texas, all of them pled some form of insanity, as
the basis for the justification of their behavior.
So it would appear to me then that while there is this
broad choice that we have as human beings, there is also
sufficient, I think, evidence worthy of study on what some of
the ``isms'' and the implications of those who are less
tolerant have been in our society, and its broad-ranging
implications.
Dr. Hyman. I agree with you. I would say one thing, so that
I do not run on too long. What we have to remember is that our
brain works in--and forgive me one sentence that may be
incomprehensible even to me--works in relatively modular
circuits. One can, on the one hand, hold a certain set of
beliefs about black people, for example, or about gays, you
know, in thinking about these cases, but that does not mean
one's whole brain is taken over by this. At another level, I
think a person has the wherewithal to know that this is not
appropriate in our society and that whatever one's beliefs,
that certain acts are beyond the pale. And I think what we are
allowing is people to generalize from deeply ingrained--let's
imagine very deeply ingrained ideas that may be racist or
intolerant to----
Mr. Jackson. Mr. Chairman, I know my time is expired, but
he just raised a very interesting point, just very quickly.
It is illegal in this society, but that does not change the
individual brain and disorder that may be a deeply held belief
for the individual--I am sorry.
Dr. Hyman. No, no. I do not want to go on for too long. Let
me just say that, remember, the brain is built not only bottom-
up by genes, but the brain is also built by our experience, and
our laws and our social beliefs are part of what built the
brain. In essence, you know, people in drug policies always
separate supply side from demand side. But the laws that have
to do with the supply side also affect the demand side because
they create the moral environment in which we should be raising
our children. It is involved in building their brains. That is
a longer----
Mr. Jackson. Thank you, Mr. Chairman.
Mr. Porter. A very interesting course of questions. Thank
you, Mr. Jackson.
Ms. Lowey.
IMPROVING TREATMENT OF CHILDHOOD DISORDERS
Mrs. Lowey. Thank you, Mr. Chairman. And welcome, Dr.
Hyman. I apologize that I came in in the middle of this very
interesting and very controversial discussion. On the one hand,
I have my colleague talking about how this child is supposed to
be taking Ritalin and is not taking Ritalin, and how are we
going to get the child to take Ritalin. And on the other hand,
another colleague is saying that maybe more mothers or fathers
should stay home and give more attention to the child, and we
are probably all right.
In New York, I am concerned about children being
warehoused, put in institutions because they are not even
examined, they do not have the mother or the father that is
going to be able to stay home with them, even if they choose to
stay home with them. And perhaps if that mother or father got
some more assistance, drugs and therapy for the mother or the
father, maybe the child would not be in such difficulty. And
let us not even talk about that 6-year-old little boy! You
probably did already.
Dr. Hyman. Yes. Yes.
Mrs. Lowey. But clearly it is very complex, and there is
never going to be enough money to do everything we should. And
it is very frustrating to all of us when we think of all of
these lost people in our society, frankly, that are not getting
help, and are being warehoused instead of getting adequate
evaluations.
Would you comment on how NIMH is helping address the
significant need, this tremendous need for better understanding
of childhood mental illnesses, better screening, better
diagnoses, better treatment. We have this constant battle going
all of the time, and I do not know how we can adequately
respond to it. If you spend ``x'' number of your resources on
the four kids in the class, how are you shortchanging the
majority of the class? And we deal with this in just so many
different areas. But I think we have to educate people and
create a better understanding, and if you can comment, I would
appreciate it.
Dr. Hyman. Well, I think your point, actually, relating to
Mr. Jackson's point and also to the discussion I had before, I
do not think anybody means there is an either/or; that pills
should never be used, pills should always be used.
Mrs. Lowey. Right.
CHILD MENTAL HEALTH RESEARCH INFRASTRUCTURE
Dr. Hyman. The problem is what you are talking about, which
is the quality of the evaluation. There are some kids, I mean,
to take an extreme case, who are banging their heads, who are
self-mutilating, who have uncontrollable aggressive rages. We
do them an incredible disservice if we do not use appropriate
pharmacologic methods.
By the same token, as I was saying to Mrs. Northrup, there
are kids out there who may be getting Ritalin really just for
the convenience of teachers and parents. And the goal is to
understand the problems of children as individuals, respond as
best you can, and then--I think this gets to the warehousing
issue--and then to keep evaluating them: Is what I am doing
working? Are the side effects intolerable? Is the kid maturing
and no longer needs this intervention? Is the kid engaged in
treatment? These are critical questions. How do we get the
information?
Well, I have already mentioned that we have initiated
large-scale clinical trials, including both psychotherapy, and
medication and the combination in adolescent depression. We
just completed one in attention deficit disorder. We are
beginning to start one in toddler attention deficit disorder, a
real public health matter. We have research. I do not want to
sit here and give you a laundry list. But I will say one thing.
Childhood mental health is the one area in the portfolio, and
this stretches all the way from autism, to anxiety, to ADHD, to
depression, where every year I would be willing to spend more
money than I am able to spend because of the lack of an
adequate number in this field of highly trained investigators.
When we funded our large-scale clinical trial in adolescent
depression, I wanted to then immediately begin one in kids
under the age of 12, especially with the goal not only of
finding out about the safety and efficacy of medication, but
getting the development of psychotherapies that would be age
appropriate. And, frankly, the infrastructure--the
investigators--was not there. It is one of my goals to be able
to initiate something like that within 3 years.
We have put together expert committees, and from the tone
of my voice, I am hopeful, but still I want outcomes, I want
results. I do not want to just have process. And one of the
things that we have tried to do is to bring pediatricians and
family doctors into this because they are the front line. We
have, I already mentioned, salary awards for anyone who wants
to get into this from the study of adults or from general
pediatrics. We must get the word out and build a cadre of
effective researchers, especially for young children. The
problems are so pressing.
Mrs. Lowey. And once you have the research, do you feel
that there is enough coordination? I mean, you have some
information and you need to do more research, obviously.
Dr. Hyman. Yes. Yes.
Mrs. Lowey. Is there enough coordination with the public
health centers, with the public health programs, with the
community health centers?
ENHANCING PROVIDERS' SKILLS
Dr. Hyman. There is not. There have been unfortunate
educational and guild issues so that, while, actually, Dr.
Robert Johnson, who is a wonderful pediatrician from the State
of New Jersey and was on my National Advisory Council, has
actually been advising us on this. There is an increase in
mental health, mental illness education for pediatricians. It
really is inadequate, given the fact that they see so much of
it, that these illnesses are so common. And breaking down
barriers between guilds, like psychiatry and psychology and
pediatrics and family medicine, is never easy. We really have
to work. I mean, even the fact that I have pediatricians on my
National Advisory Council tells you I am trying to break down
these guild barriers, which get in the way of the flow of
appropriate information.
I also would point out that I do not want to bash family
physicians. These people are under extraordinary time
pressures, and issues about behavior entail very long
conversations. Mothers have no problem bringing a child with a
cough to the pediatrician. But if a child is depressed, the
mother is fearful she is going to be blamed and often there is
a very--there has to be a very delicate interaction to elicit
the proper information.
So we have a big process ahead of us.
COMMUNICATION BETWEEN NIMH AND EDUCATORS
Mrs. Lowey. Do you have superintendents of schools, do you
have teachers, do you have anyone in the education field? Steny
Hoyer and I have been very strong advocates of comprehensive
schools. I just feel it is not sufficient today for the mother
to bring the kid to the pediatrician. We need to have these
services in the schools.
Dr. Hyman. Well, right. Schools should not just be places
where nurses have rows of pills in front of them to give out.
Mrs. Lowey. And one nurse for a thousand kids, right.
Dr. Hyman. We have had, actually, very good meetings, but
of course it is with the Federal Department of Education, and--
--
Mrs. Lowey. You talked about your advisory committee. Do
you have educators?
Dr. Hyman. No, I do not, actually, on my advisory
committee.
Mrs. Lowey. Not a bad idea, right?
Dr. Hyman. That is an interesting idea. But we have had--
that is a good idea. So okay. [Laughter.]
But we have had very good interactions with education in
the area of youth violence. There are some interesting cultural
differences between the way we would approach things. This has
to do with medicalization and the way they see things.
Mrs. Lowey. I guess I heard the bell, so I will have to
save the other questions. But, obviously, we can talk for hours
on this because it is so critical.
Dr. Hyman. These are fundamental issues for America's
children.
Mrs. Lowey. But we appreciate that you are there focusing
on it. Thank you.
Dr. Hyman. Thank you.
Mr. Porter. Thank you, Ms. Lowey.
We will take a short second round.
RATES OF MENTAL DISORDER BY RACIAL/ETHNIC IDENTITY
One of the things that we have heard repeatedly from your
colleagues, the Directors of the other Institutes, is about the
unusually high rates that minorities suffer, whether it is
heart disease or cancer or diabetes or infectious diseases. But
we have not heard that minorities suffer greater mental health
problems necessarily.
Dr. Hyman. That is correct.
Mr. Porter. Is that because we just have not done the
research on it or is it because there is greater mental health
among minorities, and they do not suffer disproportionately in
this area?
Dr. Hyman. Yes. The research is very interesting. For the
most serious mental disorders, such as schizophrenia, the rates
are eerily alike among all races, they are the same in midtown
Manhattan as in rural Kenya, which has been studied. I,
actually, went to India for reasons about AIDS behavioral
prevention, but I stopped at a large mental hospital in
Southern India and interviewed patients who could speak
English, and schizophrenia was entirely the same there. It was
really staggering.
For anxiety and depression, however, there is good evidence
that grinding poverty, that being witness to violence, to
living in a chaotic or disrupted family or a single-parent
family, conditions to which minorities are subjected much more
than the majority population, there is actually an impact on
both anxiety disorders and depression. And people like Dr.
James Jackson at the University of Michigan and Dr. Felton
Earls at Harvard, are very much involved in helping us to
understand the precise impact.
It is important, however, that just because a kid has
gotten depressed because of an experience of discrimination
that we do not fail to treat this as a real medical disorder.
These experiences initiate, in the vulnerable youngster, this
brain condition, this brain disease, depression, and we have to
then, obviously, deal with the social conditions insofar as we
can, but not neglect the medical side.
There is another issue with minority disparities which have
to do with utilization and trust. And there is a tragic
finding, from our Schizophrenia Port study, and also from prior
work of Dr. James Jackson, that black men are much more likely
than white men to get the diagnosis of schizophrenia and to be
treated with high-dose antipsychotic drugs if they have ever
had a psychotic symptom, whether or not they actually have
schizophrenia. And this, again, gets to Mr. Jackson's question
about stereotyping. And it is a very, very important area of
research.
It is interesting, the illness in our portfolio that has a
disproportionate impact on minorities is AIDS. After all, we
have the portfolio on behavioral prevention of HIV/AIDS. And
although African Americans are something like 13 percent of the
general population, they now represent 57 percent of new-
incident HIV infections. So as the demographics of the epidemic
have moved, we have focused our prevention measures, because
prevention measures have to be culturally sensitive, and as of
today, $85,000,000 of the $130,000,000 in our prevention
portfolio are focused on minorities, which is the highest
percentage of any AIDS portfolio at NIH.
PUBLIC EDUCATION ABOUT CHILD HEALTH
Mr. Porter. I am going to sneak in a second question here.
We have been talking with CDC, SAMHSA, HRSA, and others about
some method of getting out some, for want of a better term,
public service interventions--and whether they are on TV or the
Internet, we are not sure yet--that would address children's
health, and particularly behavioral; diet, exercise, avoiding
use of tobacco and alcohol at a young age, and drugs and the
like. Obviously, a part of a child's health is also mental
health. It is a very complex subject, however. Is there any way
that this subject would lend itself to a reach-out to either
children or their parents in a simple way that would impact
their habits that might improve their mental health later on?
Dr. Hyman. Yes. And as you know, we were involved with this
American Health Foundation outreach efforts for children. I
think that kids really would respond to simple messages like,
you know, everybody gets sad now and then, but it is not okay
to be sad or scared all of the time. I think kids would respond
to messages like that.
Mr. Porter. We are actively working on this, and we want to
call on you for your intellect.
Dr. Hyman. I would be delighted.
Mr. Porter. Mr. Jackson, any further questions?
Mr. Jackson. Mr. Chairman, yes, I would be happy to take
this opportunity.
I have a number of questions that I want to submit for the
record.
Dr. Hyman. Sure. Okay.
Mr. Jackson. And if you could get back to me on those, I
would be greatly appreciative.
MINORITY GROUPS' MENTAL HEALTH
I want to associate myself with the Chairman's concern
about mental illness among minorities, schizophrenia and other
fundamental behavioral disorders. I was going to indicate to
the Chairman that this is one subject matter that a lot of
minorities do not want to broach, that we might be twice as
likely to be crazy as everybody else.
Dr. Hyman. But it is not the case.
Mr. Jackson. Right, but it is not the case, and I am happy
to hear that. [Laughter.]
That there is overwhelming evidence that we have fewer
disparities in this area. That is particularly important. And I
am not picking on anyone because they are running for
President, but I just want to make a point. I do not think
anyone in this room can deny that Senator McCain's experience
as a soldier has had a profound impact on who he is as a
person, and I think a favorable profound impact. I think
millions of Americans feel very strongly about the kind of
character that his leadership represents, and I certainly feel
that strongly about him as a colleague of his.
But I also do not think that many Americans fully
appreciate the depth and profundity of these discrimination
experiences on the development of character for young African
Americans, when they experience it from the police, or members
of Congress, like myself, whenever I am trying to argue for
more appropriations funds for my district, some of my
colleagues think they are doing something for me when they have
done something for Chicago, when most of my district is out of
Chicago. They just assume that helping Chicago has helped Jesse
Junior. I say, ``No, I represent 30 cities outside of the City
of Chicago.'' But, no, you are the young African American
inner-city Congressman from Chicago, and we have done something
for Chicago. That is part of the stereotypical kind of problem.
And I say that as a member of Congress, but I would
imagine, if I were moving up the corporate ladder as a woman,
that there are a number of ``isms'' that would put me in a
position where I would have to be as tough as the guys and even
tougher than the guys in order to make it up the ladder because
those experiences, at every step of that ladder, have shaped
the culture of who we are as a Nation, same for every Asian
American, and Hispanic Americans and others who have been
victims of one of the ``isms'' that I think, personally, is
worthy of study.
What we end up finding, based upon the Nation's history and
the very structure of our Nation's Government, and this is a
political statement, is that the study of some of these
``isms'' get quite personal. I mean, the study of racism, in
light of how many Presidents we have had in one category and
how many thousands of people have been in Congress, and less
than 100 of them have been African American. The study of
racism becomes all too apparent the study of white guys. When
we talk about the study of sexism, I mean, the population is,
clearly, you have got to be a guy to be in the category, the
study of men and their behavior towards women, as it has
developed through our Nation's history and what is expected of
men in our society. How we define manhood is a factor, I think,
in that, and we try and pass it on to our sons.
Well, I guess I am suggesting that many of these mental
disorders and behavioral disorders are the sum total of our
experiences in the society. And so I am not so sure that we can
totally separate those experiences that might ultimately
culminate in criminal conduct or in a certain behavior that has
tremendous economic and legal and political consequences for
the individuals who engage in them. So I do not know how long I
am going to be on this committee, and something tells me that I
am going to get run off of here real soon by the line of my
questioning. [Laughter.]
But I am certainly hoping that over time we are at least
open to the idea of broader study on the questions that I am--I
am sorry.
Dr. Hyman. I am sorry. No, no, I am sorry.
Mr. Jackson. No, Dr. Hyman, go ahead. My time has expired.
Thank you, Mr. Chairman.
IMPACT OF LIFE EXPERIENCE ON BEHAVIOR
Dr. Hyman. Again, I wanted to reiterate that in our basic
behavioral science portfolio, we do study these. And, indeed,
we intend to study these issues more as they would impact
things that are in our clear mission, such as the risk of
depression, anxiety disorders, post-traumatic stress disorder
and youth violence among youth. And what you said, I would just
add one thing, the sum total of our experiences, plus what we
bring to the table, from our genes, our early development does
impact who we are.
And I would just, if you reflect for a second on the
behavior of human beings like you and me in the former
Yugoslavia or in Rwanda, what is it in early experience, in
devaluation of other people, how do these ideas take hold so
that you can dehumanize somebody else and then engage in that
kind of violence. Nobody flew over those countries and dropped
new DNA on the people. This really had to do with very deep-
lived experience, and it is very worthy of study.
Mr. Jackson. If I can just sneak a little point in like the
Chairman did. [Laughter.]
The only problem there is it is easy to study mice and
study raccoons and figure out their behavioral disorders. But
when we talk about some of these ``isms'' that are fundamental
to creating anxiety in many of our homes, and the
dehumanization and degradation of some of our men who come home
to their families and take it out on their wives and behave a
certain way because job after job because they are subject to
certain kinds of society-driven, self-study, amongst even white
researchers at that level, particularly white male researchers,
become something that I would imagine through the history of
the NIH is something that is not often engaged in because it is
not easy to just say, ``Well, that is just a general mental
disorder,'' when the ``ism'' itself is inherent in the culture
of the structure of the way it was set up.
Thank you very much, Mr. Chairman.
Mr. Porter. The Chair would note that when the gentleman
talks about projects and programs for the City of Chicago and
stereotyping, that occurs solely on his side of the aisle, not
on our side. [Laughter.]
Mr. Jackson. The Chairman has been generous. Thank you, Mr.
Chairman. [Laughter.]
Mr. Porter. Mr. Miller.
NIMH BUDGET DISTRIBUTION
Mr. Miller. Let me talk a little bit about budgeting issues
and some money issues. I guess that is what we are here for.
Dr. Hyman. Oh, yes. Yes.
Mr. Miller. What percentage of your money is extramural?
Dr. Hyman. It is 12 percent intramural. So I was trying to
subtract the administrative part, but it is about 85/86.
Mr. Miller. About 85/86.
Dr. Hyman. Yes.
Mr. Miller. And that is a little lower or is that about
average?
Dr. Hyman. It is about average. Our intramural program has
gotten smaller, percentagewise, with each year that I have been
director, as we have been bringing in very rigorous review.
BUDGETARY FLUX
Mr. Miller. Hopefully, Congress will continue on the path
of doubling total funding for NIH over a period of time, but
these 15-percent increases are not going to continue.
Dr. Hyman. Yes.
Mr. Miller. And then you reach the stage of, you know,
there will not necessarily be, hopefully not flat funding, but
I do not think the 15 percent will continue.
How much of your grants, extramural, these are multi-year,
most of your----
Dr. Hyman. Yes; four years, on average.
Mr. Miller. Four years, on average. So the problem we
foresee, if you start doing 5 years off, assuming there is
this, you know--you are preparing, and this is----
Dr. Hyman. Yes, we are----
Mr. Miller. All of NIH, I guess, is----
Dr. Hyman. We are very concerned about having a commitment
base which is so large that if one year we go from 15 percent
to zero, there will be no ability to fund new research in that
year.
On the other hand, we have to spend our appropriation
within the given year, and there are just so many things that
we can do to manage those concerns. We hope, obviously, that at
such a time as these healthy increases that we have been
talking about begin to taper, that it is truly a taper and not
a cliff.
Mr. Miller. Right. Just kind of briefly, with what little
time there is left, about how your research priorities and
funding priorities have changed since you have been Chairman,
head of NIMH.
REDIRECTION OF NIMH RESEARCH PROGRAMS
Dr. Hyman. I have to say I have made a very substantial
number of changes. NIMH came from, originally, another agency,
ADAMHA, and the sciences of the brain really have just been
maturing, and our science of genetics. And also, NIMH had not
had stable permanent leadership in some time when I took over.
And I did find it in need of enormous changes in priorities
and, frankly, in standards.
Although I am a psychiatrist, partly because I come from
the mainstream biology community, I was able to call on people
not only within the field, but throughout biological science--
molecular biologists, geneticists, cognitive neuroscientists--
for advice. And, in essence, we have changed the way we do
business; for example, in genetics, to recognize the complexity
of genetic risk. We have changed the way we do business in
clinical neuroscience, bringing together basic neuroscientists
with clinicians, instead of asking clinical investigators to be
all things to all people. We have changed the way we do
clinical trials to have more external generalized ability to
real-world populations. We have changed our commitment to
fundamental neuroscience, increasing it markedly. We have
refocused on the need to take basic behavioral science and make
it strong, but also have asked it to contribute to public
health issues, again, by building teams. I have refocused
prevention research from the romantic idea that we could
prevent mental illness, which we don't know how to do to the
idea of early intervention, early diagnosis.
And I can detail these things for you. It has been a very
exciting time. And there is, of course, a very talented
research field that has helped in all of this reorientation.
This is only possible, again, because of the generosity of the
American people acting through you.
Mr. Miller. Thank you.
Mr. Porter. Thank you, Mr. Miller.
Mrs. Lowey.
Mrs. Lowey. Incidently, Mr. Chairman, I am not sure if I
mentioned that even though Yale, and Harvard and Cambridge can
all claim you, that you did grow up in New York, so I am
particularly proud.
Dr. Hyman. I did. Upper West Side.
Mrs. Lowey. Well, I grew up in the Bronx, but it is close.
Dr. Hyman. My mom came from the Bronx.
Mrs. Lowey. I knew it. I knew it. I had a feeling.
Dr. Hyman. Walton Avenue.
Mrs. Lowey. So did I.
Dr. Hyman. Really? Yeah. Yeah. [Laughter.]
Mrs. Lowey. Not 975 Walton?
Dr. Hyman. That, I do not know. Near Yankee Stadium.
Mrs. Lowey. So did I. [Laughter.]
PREVENTION RESEARCH
I just suspected good, strong roots, Mr. Chairman. We will
have to continue that.
Thank you. I will try to be brief because I know we have
another hearing, and I know you did comment on your work in
trying to reshape research priorities at the NIMH to reflect
public health needs, and this is along your discussion.
In several recent Mental Health Advisory Council reports,
you have recommended improving the relevance of prevention
research into early interventions.
Dr. Hyman. Correct.
Mrs. Lowey. Clinical research to actual practice,
behavioral research to serious mental illness.
Dr. Hyman. Correct.
Mrs. Lowey. And I understand that changing research
priorities at a place like the NIMH is not easy when you are
dealing with such large institutions. But if you can discuss
sone of the successes, some of the difficulties to change the
Institution's direction.
Dr. Hyman. This actually continues from Mr. Miller's
question.
Mrs. Lowey. Exactly.
Dr. Hyman. Exactly. Well, scientists, although we are
objective, of course, we also, like all humans, get into
patterns of doing business, and often it is very hard to change
the way people do research. And what I have invariably done, as
I mentioned, is called on the very best people outside the
Institute, often people who are not directly in this field.
There have got to be some people who do not have necessarily a
vested interest in the field, and also outstanding people who
you want to seduce into your field because you get them
involved in the planning process.
And then I have taken these reports or actually they have
been developed through our National Advisory Council, and there
is always a healthy debate and public announcement. And then we
have been pretty tough about changing policy; meaning, we will
make an announcement that grant funds are available for this
and that, that area of research, which was terrific 10 years
ago, but is no longer relevant, we are just going to start
phasing it out. And it has not always made me popular, but I
think it is the only way to operate. Indeed, I think, just from
my opening comments about this committee's and Mr. Porter's
demand for high standards, I think it is precisely at a time
when we are getting these healthy increases, that instead of
allowing older ways of doing business to just continue, this is
the time to make changes and always to point toward new
opportunity instead of sort of getting into a rut.
Mrs. Lowey. I think that bell counted our Walton Avenue
discussion. [Laughter.]
Mr. Porter. Hey, you chose it. [Laughter.]
Mrs. Lowey. Well, we will let it be.
Mr. Porter. If Nancy was here, she would say you probably
went to San Francisco, too, right?
Dr. Hyman. Yeah. That is right. [Laughter.]
I visited.
Mrs. Lowey. I will have to submit the next question, but I
thank you.
Mr. Porter. Dr. Hyman, we actually have gone way over our
time, and that is the Chair's fault. But the discussion is
fascinating to us, and we have been discussing with Dr.
Kirschstein ways that we can get some of this into the minds of
other members who are not privileged to be members of this
subcommittee. I believe, Ruth, if we had a camera here, and I
will not be here to do this, but if you had a camera here,
videotaped all of the testimony of all of the Directors and
then have somebody edit it and put it together and send it to
the members, they might have a chance to get some of the flavor
of the wonderful experience those of us who are members of the
committee get from listening to the directors.
Dr. Hyman, you do a marvelous job. You have educated us
greatly. The discussion this morning has been just fascinating,
and we cannot tell you how much we appreciate the outstanding
work that you are doing there and how much we want to give you
the resources to continue it and expand it.
Dr. Hyman. Great. Thank you very much.
Mr. Porter. Thank you.
Dr. Hyman. Once again, a special thanks to you, Mr. Porter.
Mr. Porter. Thank you, Dr. Hyman.
The subcommittee will stand briefly in recess.
[The following questions were submitted to be answered for
the record:]

NATIONAL INSTITUTE OF DIABETES AND DIGESTIVE AND KIDNEY DISEASES
WITNESSES
DR. ALLEN M. SPIEGEL, DIRECTOR, NATIONAL INSTITUTE OF DIABETES AND
DIGESTIVE AND KIDNEY DISEASES, NIH
EARL LAURENCE, DEPUTY DIRECTOR, NATIONAL INSTITUTE OF DIABETES AND
DIGESTIVE AND KIDNEY DISEASES, NIH
CHARLES R. ZELLERS, FINANCIAL MANAGEMENT OFFICER, NATIONAL INSTITUTE OF
DIABETES AND DIGESTIVE AND KIDNEY DISEASES, NIH
DENNIS P. WILLIAMS, DEPUTY ASSISTANT SECRETARY, BUDGET, DEPARTMENT OF
HEALTH AND HUMAN SERVICES
DR. RUTH L. KIRSCHSTEIN, ACTING DIRECTOR, NIH
Mr. Porter [presiding]. The subcommittee will come to
order. We continue our hearings on the budget for the National
Institutes of Health with the National Institute of Diabetes
and Digestive and Kidney Diseases. We are pleased to welcome
for the first time Dr. Allen Spiegel, the new Director. Dr.
Spiegel, we are delighted to see you in this position. You have
been with the Institute for 27 years, I am told, which is a
long time, but now you are the director and we are pleased to
have you here and look forward to your testimony.
OPENING STATEMENT OF DR. ALLEN M. SPIEGEL
Dr. Spiegel. Thank you very much, Mr. Porter. I would like
to begin by introducing Mr. Earl Laurence, who is our deputy
director, immediately to my left; Mr. Charles Zellers, who is
our budget officer, to my far left. I believe you are familiar
with both Dr. Ruth Kirschstein and Mr. Dennis Williams.
Mr. Chairman and Members of the Committee, I am pleased to
testify on behalf of the National Institute of Diabetes and
Digestive and Kidney Diseases, particularly as NIDDK marks its
50th anniversary this year. As you heard, I have been with the
institute for nearly 27 of those 50 years, but just for the
past 3 months as institute director. The challenges poised by
the diseases within the NIDDK mission are enormous, yet we are
poised as never before to make dramatic progress by using new
powerful research tools, including, for example, genomics,
bioinformatics, animal models of disease, and noninvasive
imaging methods. All of these tools are generating new
knowledge that will, I believe, revolutionize the treatment and
prevention of the diseases within the NIDDK mission. Thus, I
have a real sense of excitement and optimism in accepting the
challenge as director of NIDDK of leading the effort to
alleviate the burden of diabetes, endocrine and metabolic
disorders, digestive and nutritional disorders, kidney,
urologic and blood diseases.
POLYCYSTIC KIDNEY DISEASE
One of my main goals as institute director will be to
strengthen the connections between basic science and clinical
research in order to accelerate progress. I will provide, in
the interest of time, just three brief examples of how we can
move from basic science to clinical advances. Polycystic Kidney
Disease, or PKD, is the fourth leading cause of end-stage
kidney failure. Basic research led to the discovery of 2 of the
genes that cause PKD. This in turn permitted clinical studies
that showed that cyst formation, which is the fundamental
abnormality in PKD, like benign tumor formation, is an abnormal
growth process.
Just within the past month, NIDDK-supported investigators
using a drug that blocks growth by targeting a growth factor
receptor, were able to show that they could block cyst
formation and enhance survival in an animal model of PKD. This
holds out real promise for eventual treatment of the human
disease.
HEPATITIS C
Let me turn as a second example to hepatitis C which, as
many of you know, affects an estimated 4 million Americans and
is the most common reason for liver transplantation in the
United States. Basic research first led to the discovery of the
virus. This permitted methods to diagnose the disease and
measure the virus in the blood and eventually led to clinical
studies, which have culminated in the demonstration that anti-
viral agents in combination, interferon and Ribavirin, are able
to clear the virus from the blood of as many as 40 percent of
infected patients. This is not good enough, though. We are now
launching new initiatives aimed at increasing the effectiveness
of anti-viral drug treatment and also combatting the
disproportionate burden this disease places on African-
Americans.
DIABETES RESEARCH
Certainly, I believe one of our greatest challenges is
diabetes. I could recite the statistics on the millions of
Americans of all socio-economic groups that are affected and
the devastating complications, for example, kidney failure,
blindness, amputation and heart disease. But these numbers
alone do not adequately depict the plight of the patients,
young and old, suffering from diabetes. Fortunately, basic and
clinical research offer hope to those who already have the
disease and those who are at risk of developing it in the
future. In type 1 diabetes, we have learned much about how the
immune system destroys the insulin-secreting beta cells.
Advances in genetics and immunology have led to candidate
interventions to reeducate the immune system and allow us to
prevent beta cell destruction. We have also learned how reduced
insulin secretion and resistance to the action of insulin cause
type 2 diabetes. Mutations in several genes causing rare, early
onset forms of the disease have already been identified, and in
each case they have been shown to impair insulin secretion.
A subtle defect recently in one of these same genes has
been discovered in patients with the more common form of type 2
diabetes. In related research, a new class of diabetes drugs
that act by increasing the sensitivity to insulin action was
shown to work on a cellular receptor termed PPAR-gamma. Now, in
very recent work, mutations and defects in the gene for PPAR-
gamma were identified in some patients with type 2 diabetes.
This provides further evidence of the critical importance of
this receptor protein in insulin action.
Let me summarize that clinical trials have already
convincingly demonstrated the importance of maintaining
excellent control of blood glucose in preventing or delaying
the onset of diabetes complications. But tight control through
careful monitoring of blood glucose and multiple daily
injections can be both difficult and frustrating, especially in
children with type 1 diabetes. Thus, the NIDDK is committed to
supporting research to improve existing insulin treatments and
to find innovative new treatments that will represent a true
cure for this disease.
PANCREATIC ISLET CELL TRANSPLANTS
I call your attention to the figure on my left. As shown in
this figure, normal stable levels of blood sugar can be
achieved in monkeys lacking a pancreas who have received a
pancreatic islet cell transplant. In contrast, the 4-year-old
child with type 1 diabetes depicted here, despite intensive
insulin therapy, has, as seen in the jagged line above, wildly
abnormal fluctuations in blood sugar. Importantly, these
excellent results in the transplanted monkeys were achieved
with an innovative form of treatment that allows acceptance of
the transplanted islets without chronic immuno-suppressive
drugs. Even though it is clear that these studies are very much
in their infancy, we have been sufficiently encouraged to open
an entirely new branch in the NIH Clinical Center dedicated to
exploring this and related types of treatment in both kidney
transplants and islet transplants.
These few examples, I believe, show only some of the
remarkable progress we are achieving in biomedical research
related to diseases within the NIDDK mission. Clearly, though,
many, many challenges and opportunities remain. Minorities, for
example, are disproportionately affected by type 2 diabetes,
hepatitis C, and end-stage kidney failure, all diseases within
the core mission of NIDDK. We are committed to addressing those
significant issues in a variety of ways, but I will cite just a
couple of examples.
DIABETES PREVENTION PROGRAM
Our Diabetes Prevention Program is a large multi-centered
trial aimed at testing a variety of interventions that could
prevent or delay the onset of diabetes in high-risk
individuals. The study is notable because it has enrolled
approximately 50 percent of the subjects from minority groups
that are disproportionately affected. We are also supporting an
entirely new initiative aimed at the alarming incidence,
particularly among minority groups, of type 2 diabetes in
children. We are furthermore supporting efforts to understand
why Native Americans and African-Americans show an increased
susceptibility to the kidney complications of diabetes.
DIABETES RESEARCH WORKING GROUP
We will also be actively pursuing the five areas of
extraordinary opportunity--genetics, autoimmunity in the beta
cell, cellular signalling, obesity, and clinical trials--that
were outlined by the Congressionally-established Diabetes
Research Working Group. In the interest of time, I will
elaborate on this during the question-and-answer period with
specific examples of what we are doing and what we plan to do
in these areas.
In my very first few weeks as NIDDK Director, I have been
meeting with a large number of groups, both lay and scientific,
that represent the NIDDK constituencies. I expect in the future
to reach out to those and other groups within the NIDDK family
to work together with them and our superb National Advisory
Council to frame a collaborative research agenda for the
future. I believe that working together, we can take full
advantage of this unique moment of scientific opportunity for
the benefit of all of the people of this country. I am pleased
to present the President's non-AIDS budget for NIDDK for fiscal
year 2001: $1.186 billion, an increase of $66,800,000 over the
fiscal year 2000 appropriation.
Mr. Chairman, if I may, before accepting questions, permit
me to note that one of my few disappointments in becoming NIDDK
Director was the knowledge this would be your last year as
Chairman of this subcommittee. I would like for myself and on
behalf of my colleagues in NIDDK, to thank you for all that you
have done for biomedical research. I now will be pleased to
accept questions.
[The written statement of Dr. Spiegel follows:]
DIABETES RESEARCH ADVANCES
Mr. Porter. Dr. Spiegel, thank you for your testimony and
for your kind words about my retirement. I think it is fair to
say that there is a great deal of excitement about your
leadership at NIDDK, particularly among the patient advocacy
groups. You have been at NIH for 27 years beginning as a fellow
in 1973, and you have seen a great deal of research done on
diabetes. Is it fair to say that while we have developed better
means of diagnosis, better means of treatment, and better means
of taking care of the complications of diabetes, that there
hasn't been a lot of progress up to this point on understanding
the disease and reaching the point where we feel we are making
real progress on it. I get that feeling. I wonder, you said
that you weren't going to recite the statistics, but is it not
true that this is a disease that is getting more prevalent
rather than less prevalent and affecting young people,
particularly more than it used to? In other words, up to this
point, aren't we really just barely holding our own in this
battle and not making a lot of progress?
Dr. Spiegel. I wonder when we will get to the tough
questions. Let me respond in the following way, Mr. Chairman.
First, I know that the parents of children with type 1
diabetes, the relatives and patients themselves with type 2
diabetes, are anxious and eager for cures and prevention. I
absolutely empathize and wish we had these yesterday.
Unfortunately, research in areas that are as complex and
difficult as both type 1 and type 2 diabetes seems to be
painfully slow. I agree with you. I have been with the
Institute all of these years and I have observed lots of
diabetes research taking place. And one could take the
perspective of, ``Have we really made progress?'' I would argue
strenuously that not only have we made very good progress but,
as I implied in my opening statement, I believe that we are on
an accelerating course to be able to make even more substantive
progress given the very generous support that Congress has
provided us.
Let me be specific for a moment. It is absolutely true that
we need to keep this distinction between type 1 and type 2
diabetes in mind. Type 2 diabetes, the more prevalent form,
according to the American Diabetes Association involves as many
as 16 million Americans. Many don't know they even have the
disease--it seems to be an epidemic. Obesity is a very
important predisposing factor and that certainly seems to be an
epidemic. No question that is growing.
Type 2 diabetes in children, not the autoimmune destruction
of the beta cells, but the same disease that we see in adults,
is also increasing. We are aware of this and we are launching
initiatives, as I mentioned, in this direction. Whether the
other form, the autoimmune form, type 1, is increasing in the
United States, is not so completely clear. There are some bits
of evidence that it may be. The fact is that with as many as
800,000 Americans, perhaps even a million involved, it is still
too large a number by any stretch of the imagination.
GENETICS OF DIABETES
Where is the evidence that we are making some headway? I
will just mention the areas of extraordinary opportunity that
are in the DRWG report. First, if you look at genes, several
genes that predispose to type 1 diabetes have already been
discovered. I know you were at the groundbreaking ceremony for
the NIH Clinical Research Center, and perhaps you will recall
former Senator Hatfield's comments there: ``If you tell me you
have identified a new gene for the disease, I will be
interested; but if you tell me you can do something about it, I
will be excited.''
I can relate to and understand what he is saying. It is
important to understand that identifying these genes is a
critical first step. By doing so in type 1 diabetes, we can
determine who is at risk and test various preventive measures
at various stages at the disease. We are doing exactly this and
there are new candidate interventions. In type 2 diabetes,
genes have already been discovered, as I indicated, and some of
these, as in the case of this new class of drugs I mentioned,
are already lending themselves to therapy.
If we take autoimmunity and the beta cell, the islet
transplant example I gave is an important example. Islet
transplants--and this perfectly echoes what you said--have been
around for years and have not been very successful. But now
with newer methods of harvesting these islets, with newer
methods of establishing immune tolerance, they may succeed.
Obesity, a predisposing factor for type 2 diabetes, is an
enormous problem, and yet with the discovery of leptin and
other pathways involved in the regulation of fat we are making
real headway.
And finally, our major clinical trials that we are
supporting will have public health impact, as well as pilot,
small clinical trials to move quickly from basic science
discoveries to an impact on the patient. I would summarize by
saying that I share your impatience and those of the patients
out there who are anxiously awaiting treatments and cures and
prevention, but I really do believe that as we look back over
just the last few years, substantive progress has been made,
and with the appropriate resources, will continue to be made.
DIABETES RESEARCH WORKING GROUP
Mr. Porter. I can squeeze in another question. What kind of
impact on the kinds of scientific opportunities that you have
been describing would it have if we could get to the level of
funding suggested by the working group? In other words, is more
money faster going to get us where we want to go faster? Is
there that much light at the end of the tunnel or not?
Dr. Spiegel. Let me just respond by saying that I am very
much in accord with the scientific opportunities as outlined in
the DRWG report. They do represent a road map for phenomenal
progress. Working within the confines of our existing budget,
we are attempting to address each of these areas as best we
can. I believe that the record will show that NIDDK is
attempting to support these areas by at least 2 percentage
points--and it may end up being more--than the overall increase
that the Institute received. Clearly, in several ways having
additional resources could: (A) allow us to move faster, and
(B) on the issue of genes and clinical trials, the power of
such studies is always greater when you have larger numbers of
individuals, but this is more costly.
Finally, even though it is critical to prioritize, you
can't take every path--but many apparently good science steps,
different interventions for example, would be worth supporting
if we could. Of course, how many of those different paths we
can simultaneously support, for example in diabetes prevention
trials, depends on the level of resources.
Mr. Porter. We probably ought to remind ourselves that
money alone doesn't do it necessarily. Richard Nixon declared
war on cancer 30 or more years ago, and we poured a lot of
money into that research. While we made progress recently, for
a long time we didn't make much progress. We did a lot of
research, but we didn't find what we were seeking and hoping
that the money would get us. I think there is now great hope in
this area, and obviously it is an area that affects so many
Americans, including members of my own family, that I think we
ought to pursue the good science that is available, and I
appreciate your answering my questions.
Ms. DeLauro.
GENETICS OF DIABETES
Ms. DeLauro. Thank you, Mr. Chairman. Just to follow up
what you have been talking about, I have two constituents here,
Paul Rossi and Vera Updike, who represent the Juvenile Diabetes
Foundation of New Haven, both of whom have daughters with type
1 diabetes. You started to talk, Dr. Spiegel, about the
identification of the gene that leads to diabetes. Let me just
ask you about gene therapy and what is your sense of that, and
if that is what you were leading up to talking about, do you
think we are going to see gene therapy available. I can't ever
ask you to guess about time to identifying the screen for
ovarian cancer, but because of what the Chairman was talking
about, we are trying to go a long road here. Where are we on a
time frame?
Dr. Spiegel. Since you raised the subject of gene therapy,
let me address it head on. First, despite the very untoward
recent events, the fact is I firmly believe that gene therapy
will eventually represent an important treatment of many
diseases. It is important not to ``overhype'' this. If you look
at monoclonal antibodies, 20 years ago--and this comes back to
Mr. Porter's comments--they were hyped as ``magic bullets'' and
nothing happened. Now we have biotech companies making
monoclonal antibodies, Herceptin, as an example for breast
cancer, and there are numerous others including Infliximab, a
monoclonal antibody for Crohn's disease. I believe that
eventually gene therapy approaches will also be successful.
But as we look into the Orkin-Motulski report, we need a
lot of basic science to study the vectors and the way of really
being able to deliver this in a safe way. Now, specifically to
your question with diabetes, our institute, with the
sponsorship of several of the other institutes at NIH, co-
sponsored in November a workshop on gene therapy in diabetes.
In fact, there are at least 3 conceptual areas where it may be
useful. We expect as an aftermath of that workshop to issue a
request for proposals and applications relating to gene
therapy. One would be specifically in terms of the
complications. For the wounds, the amputations we hear about in
terms of foot ulcers, there are growth factors that can help in
wound healing and delivering them by gene therapy may be
therapeutic. This needs to be tested.
A second area is in prevention of beta cell destruction. We
know that it is an imbalance of various proteins in the body
that lead to this destruction. By using a gene therapy approach
directed at the beta cells, we might be able to stave off or
prevent that kind of destruction. Those are the two areas we
are expecting to support. A third area is actual insulin
replacement by gene therapy. A paper in Science from a biotech
company just within this month indicated a very novel approach
that worked in animals. Will it work in humans? It is not
clear. But this offers promise. Again, you are absolutely
right, we need to have a long time line. We shouldn't overhype
this.
INTERSTITIAL CYSTITIS
Ms. DeLauro. Thank you. Let me move to another area, and
again, it is constituent-based. I have a constituent who
suffers from a debilitating disease of the bladder known as
interstitial cystitis or IC. She winds up battling with the
insurance company and also dealing with a disabling chronic
pain, a pain so bad she can no longer work outside of her home,
and so her quality of life has clearly suffered. First, can you
tell me how much NIDDK spent last year on basic research on
interstitial cystitis and how much more was this than the
previous year?
Dr. Spiegel. This disease is one of the things that I
really had to learn about from the ground up becoming NIDDK
director. In my intramural role, I was not familiar with it.
The way that I learned about it was we have a superb division
director in this area who spearheaded our efforts. I met with
the Interstitial Cystitis Association very early on and have
learned how frustrating and difficult this disease can be. I
believe that the amount of support for IC has grown
dramatically within NIDDK over the past three years. It is
estimated to be $11,800,000 in fiscal year 2000 and to grow
further in fiscal year 2001. There is definitely a treatment
trial with an agent called Elmiron under way which is supported
by the Institute. It is too early to tell whether this will be
successful. Most importantly, we are trying to address this not
only on a basic level but an epidemiological level. We have
sent out a request for proposals for a urology in America
database. This will help to address how prevalent the disease
really is, and what will be the diagnostic and symptomatic
criteria. So we are committed to addressing this very, very
important problem.
Ms. DeLauro. What we are talking about is the
epidemiological study that was done this spring?
Dr. Spiegel. Exactly. We have convened various
epidemiologists and urologists and we have close ties. Again,
with the help of the Congress, we have a slightly expanded
budget but still a very low Research Management and Support
(RMS) figure. We have been able to hire a basic urologist who
will oversee our bladder programs. Indeed, we are addressing
this at the epidemiologic and clinical level, but also at the
basic level, because as I stress, the basic science is key. So
the overall condition, the painful bladder syndrome, of which
IC is a part--it is one that we are very mindful of and are
supporting significant research.
Ms. DeLauro. Just to reinforce, Dr. Briggs indicated that
there would be an epidemiological study sometime this spring. I
also wanted to add that we have heard from so many people what
a terrific job you are doing and we are delighted that you are
there. Mr. Chairman, I am just going to submit a question which
will be on Cooley's anemia. My time has expired. Thank you very
much, Dr. Spiegel.
Mr. Porter. Thank you, Ms. DeLauro. The subcommittee is
currently operating under the 6-minute rule. We have, in
addition to NIDDK, the National Library of Medicine to hear
this afternoon.
Mr. Bonilla.
TYPE 1 DIABETES PREVENTION
Mr. Bonilla. Thank you, Mr. Chairman. Dr. Spiegel, I was
pleased to hear about NIDDK's plans to support the promising
areas of diabetes research as laid out in the Diabetes Research
Working Group report. I want to ask a couple of questions
related to this research. In your testimony, you mentioned that
current NIDDK studies on type 1 diabetes, particularly studies
on genetic predisposition to the disease, you talked about, and
Ms. DeLauro talked about that as well. Could you expand on the
status of these studies and other NIDDK studies focusing on
prevention of juvenile diabetes in children?
Dr. Spiegel. Absolutely. The prevention studies that we are
currently performing include a very large trial with the
acronym DPT1, for diabetes prevention trial for type 1, which
looks at first degree relatives of people with type 1 diabetes,
screens them for evidence of markers in the blood, antibodies
against the beta cell, and then tries two forms of
intervention. It sounds counterintuitive, but oral insulin or
injected insulin might serve as a way of reeducating the immune
system. For one of those arms of treatment the study has
recruited its target goal and it is near recruiting the target
goal for the other arm. It will still be at least a couple of
years, if not slightly more, before we have an answer. This is
one of the major trials we are investing in. Because of the
accelerated pace of knowledge in this area, I met with the
investigators in that area and others from around the world in
a meeting recently in January. It is clear that we need to
simultaneously launch pilot interventions, using the same
clinical infrastructure, for other promising types of immune
re-education. Those haven't yet been launched, but we intend to
do that with the appropriate resources within the next fiscal
year. This will be a kind of diabetes trial net, to allow us to
pursue pilot interventions for things that show promise to be
able to prevent type 1 diabetes.
Mr. Bonilla. Is immune system re-education a fairly recent
development?
Dr. Spiegel. Yes and no. It is recent in terms of coming to
the point where we consider testing it in humans. It is not
recent in the sense that the basic science underpinning, the
understanding of the intricacy of the immune system, is a
years-long enterprise, but one that has been accelerating. The
islet transplants figure I showed is yet another example of
educating the immune system. I feel confident without putting a
time frame on it that this will lead to a successful
conclusion.
END-STAGE RENAL DISEASE
Mr. Bonilla. A lot of us are huge advocates on this
subcommittee for the work that you do. Chairman Porter raised
an interesting question whether or not we are making
significant progress relative to the amount of money we are
investing. It was a good point that he raised, but you should
know that we are going to give you all of the help that we
possibly can. Many of us are committed on the subcommittee to
doing that, to continue doing that as we have in years past.
I have one final question here. As you know, Dr. Spiegel,
more than 350,000 Americans have end-stage renal disease, but
many more are at risk for the disease that could benefit from
prevention strategies. Last year this committee expressed
interest in exploring opportunities to develop early prevention
technique interventions to slow the progression of kidney
failure. On page 40 of your budget justification, you discussed
some initial plans for NIDDK studies in this area. Could you
elaborate on those plans, first of all, and tell us how could
we include primary healthcare practitioners in the development
and implementation of such early intervention strategies. Two
parts to the question.
Dr. Spiegel. I appreciate that question. Again, let me try
to be brief. First the meetings that we have had with the
American Society of Nephrology and with the National Kidney
Foundation have led to very concrete plans to evaluate and move
forward with the so-called National Kidney Education Program.
The data on end-stage kidney failure in this country are
staggering. Of course, there is a coincidence with diabetes
there. Fully 44 percent of those cases are coming from
diabetes. It is critical that we address it. Shockingly and
surprisingly to me, we know very little about the progression
before patients reach the end-stage renal failure. So it is
this progression that we are going to need to evaluate in terms
of the best interventions. There are certain kinds of drugs for
blood pressure lowering, the so-called ACE inhibitors that may
prevent kidney failure. The question of measuring protein in
the urine as a screening method needs to be evaluated. We
intend to convene the very best experts in all of these areas
to determine: can we mount an effective public education
campaign that would be a worthwhile National Kidney Education
campaign in the same vein as the anti-hypertensive and anti-
cholesterol programs of NHLBI.
In terms of implementing that campaign at the level of the
primary practitioner, I think it is critical that we be able to
demonstrate with evidence-based medicine that such screening
measures, for example for urine protein, would be cost
effective and relevant. This is going to require perhaps
clinical studies, appropriate targeted studies. But I think it
is critical that we move in that direction.
Mr. Bonilla. Dr. Spiegel, thank you very much. I may have
some questions for the record. Thank you for coming here today.
Mr. Porter. Thank you, Mr. Bonilla.
Mrs. Northup.
GENE THEREAPY AND ITS ALTERNATIVES
Mrs. Northup. Thank you, Doctor. I would like to pursue the
question on the time line and ask you about the question of
gene therapy versus other initiatives you are talking taking. I
do believe that the gene investigations are very important in
terms of overall direction, and NIH is clearly the organization
to coordinate that across the country. But I do have some
questions, that we are looking so far down the road at those
opportunities that we are maybe failing to fund and address
nearer at hand approaches to treating people, preventing it,
and possible cures. You know, I guess I feel that in terms of a
whole new approach, it is great. It is still so unclear to me
when we will ever really know that we will get clear enough
information to apply it, that maybe we are overlooking
applications today that would bring us quicker results.
Dr. Spiegel. Let me address that in the following way.
First of all, prevention is absolutely critical wherever we
have the means to implement it by whatever techniques, whether
behavioral, public health methods, or, in certain cases,
vaccines. What about those who already have the disease though,
where it can't be prevented? We have to come to grips with
that. Your point about prevention is obviously critical. I want
to correct perhaps a misimpression. Maybe I sounded impassioned
about gene therapy. The sole justification for investigating
genes and understanding what all of the human genome consists
of is not to do gene therapy. There are many short-term payoffs
both in terms of diagnosis, prevention, and, indeed, of knowing
who is at risk. I could give you an example for sickle cell
anemia, if I might, just as a brief way of capturing this.
Just recently a publication on an animal model, a mouse
model of sickle cell anemia, showed a gene therapy approach of
raising fetal hemoglobin which was very effective in these mice
of curing what is very similar to the human disease. That is
great, but you are right; how long will that take in humans? It
may take long, yet we may eventually get there. At the same
time there are other studies using agents like hydrea and other
types of drugs that have been shown to be effective in multi-
center trials. They are not the perfect answer, but they are a
lower tech but effective approach to some extent. I think it
comes back to what I was saying earlier, we need to be able to
travel multiple paths. We need to be able to do the best we can
do now in real time with the available evidence. But that
doesn't mean that we should shoot for the sky. We should always
aim high for the thing that will be most effective eventually.
Mrs. Northup. I think you just gave a perfect example. I
raised the question last week about sickle cell anemia and some
of the trials that looked very promising regarding bone marrow
transplants where you don't have to have exact matches and you
don't have to do total ebullition, yet they are very lowly
funded compared to the amount of money and hope we are placing
with gene therapy. I have wondered, in sort of along the same
lines that Mr. Porter raised, that we seem to be going so
slowly down the road to finding real cure, real cure. It may
eventually be that we will have to travel the whole road
through the genetic. But in the meantime, I am concerned that
we are not funding closer at hand possible cures.
Dr. Spiegel. I read your questions to Dr. L'enfant and his
responses along these lines. I am very respectful of what you
are saying and share your views. Let me just illustrate. Dr.
Griffin Rogers, an African-American who is the first branch
chief in NIDDK that I named while intramural director, is a
pioneer in the study of treatment of sickle cell anemia. He is
currently launching specific hematopoietic stem cell transplant
therapy studies. This is not the totipotential stem cell, these
are blood stem cells that in a partial way without what is
called ablative therapy may be able to address the problem of
sickle cell anemia. Certainly we are attempting to cover all
bets. In a way, it is hedging your bets but as I implied, that
is important. We can't be focused solely on some distant
future. That is not soon enough, but we can't ignore those
possibilities.
Mrs. Northup. I am not saying that you are ignoring them. I
am saying that you may be underfunding them so that they are
not moving as quickly as they could be, or we are not getting
the test number of patients to the level that we could make
better application of these. It is a relative question rather
than an open or shut door on these.
Dr. Spiegel. I really appreciate your input and this is
something that we will have to reevaluate in light of what you
are saying. I appreciate your comments.
Mrs. Northup. Mr. Chairman, I think that is all. I have
some other questions that I will submit for the record, but
those are the main questions.
Mr. Porter. Thank you, Ms. Northup.
Mr. Jackson.
Mr. Jackson. Thank you, Mr. Chairman, and thank you, Dr.
Spiegel, for your testimony today. I must tell you that you
began your testimony so enthusiastically I thought you were
going to announce a cure for diabetes.
Dr. Spiegel. I wish that I could. That is what I would most
like to do.
HEALTH DISPARITIES RESEARCH
Mr. Jackson. Let me also congratulate you in your new role
as the director of the Institute. The President's fiscal year
budget for NIDDK is $1,186,000,000, an increase of $66,800,000,
and a 6 percent above fiscal year 2000 level. Included in this
total is $34,000,000 for the following NIH areas of priority:
New approaches to pathogenesis, $4,000,000; new preventative
strategies against disease, $5,000,000; new avenues for the
development of therapeutics, $2 million; genetics of medicine,
$8,000,000; advanced instrumentation, $1,000,000; and health
disparities, $14,000,000.
I was reading a very interesting article that indicated
that the President has made a commitment to the Nation to an
ambitious goal by the year of 2010 of eliminating the
disparities in six areas of health experienced by racial and
ethnic minority populations while continuing to make progress
on the overall health of the American people. It just so
happens that one of the six areas that the President has put
particular emphasis on is diabetes, diabetes research, but most
importantly, eliminating--the President says--the disparities
that presently exist between the majority population and ethnic
minorities.
My question for you is based upon your budget request of
$1,186,000,000, and your 6 percent increase over the fiscal
year 2000 level, do you believe that the President's request
are on target toward eliminating those disparities by 2010?
Dr. Spiegel. What I would say is that working within the
envelope of the President's budget, working within that
context, it is an extremely high priority to address these
problems in terms of the disproportionate effect that type 2
diabetes and other diseases that I have mentioned have on
minorities. One gets into definitional problems in terms of
singling out these areas of emphasis that you refer to. We have
a figure, which nominally is on the order of $88 million within
the institute that is very specifically targeted to minority
health research. Much of what we do is in the areas of
hepatitis C and type 2 diabetes, and some of the other diseases
in terms of basic fundamental work, is surely relevant.
I would just briefly respond by saying that this is an
incredibly important priority to me. How could it not be, given
the fact these diseases are within the core mission of NIDDK,
but we must not overpromise. NIDDK and indeed NIH alone cannot,
by themselves, eliminate these disparities. But I think by
highlighting the areas where there are disproportionate effects
on minorities, by trying to understand the scientific basis, by
developing better treatment, by making sure that minorities are
included as I alluded to in our important clinical trials, I
will do my utmost to address this within the context of the
budget.
Mr. Jackson. I appreciate that, Dr. Spiegel. But one of my
concerns here is the President's goal of eliminating the
disparities by 2010 has very little to do with your own
inclusive programs in your department, which I think are
important. It is clear that you have the commitment to address
some of the disparities in terms of where the resources are
going and access to those institutions that are producing
minority researchers. But the President here set a very
ambitious goal of eliminating the disparities in six areas of
health. I am just wondering if you are part of any of the
coordination associated with the 2010 plan.
OBESITY RESEARCH
Dr. Spiegel. We are part of the coordination to the extent
that our Diabetes Division has participated in that area, the
obesity area which is an important part of this as well,
requiring appropriate nutrition and physical activity. We are
actually doing some of these things. The Diabetes Prevention
Program that I mentioned that has 50 percent minorities, which
include Native Americans, Hispanic Americans, African-Americans
from all over the country is testing not only drug
interventions but healthy lifestyle modifications of diet and
exercise. So we are committed to doing these things. We are
coordinating in terms of nutrition in these other areas. We
have led the trans-NIH effort in the obesity preventive
initiative. Again, I come back to the point that we need to
strain to do the utmost that we can within the budget context
that we are given.
HEALTH DISPARITIES RESEARCH
Mr. Jackson. Can you say with some certainty how much of
your budget has been dedicated to help disparities in fiscal
year 1999 and fiscal year 2000?
Dr. Spiegel. Again, coming back to this strict definition,
this would include a sum for training minority investigators,
for a variety of supplements and education at all levels. We
participate and have participated in training at every stage
from high school through graduate and medical school. The
figure for 1999, as I quoted earlier, is on the order of
$88,000,000. But in my own estimation, this is really the most
narrow, restricted definition. Many of the other things that we
are doing are fundamental to these diseases as well. For fiscal
year 2000, the estimated budget is $98,900,000.
MINORITY INVESTIGATORS AND NIH PEER REVIEW
Mr. Jackson. Let me ask you a question, Dr. Spiegel, since
I still have a little time and the little bell hasn't gone off
yet. The chronicle of higher education a few years ago wrote an
article that said there was a racial imbalance at NIH. Let me
just read a couple of paragraphs of that to you. It says--it
begins--by Steven Byrd, ``that while scholars received 90
percent of the research grants awarded competitively by the
National Institutes of Health in 1991 according to a study by
the agency. The study found in the same fiscal year, Asians had
received about 8 percent of such grants, Hispanics 1.5 percent,
and blacks about .4 percent. Those rates have been fairly
consistent over the last decade,'' the report on the study
says.
Then it went on to say that ``many representatives of
minority groups say that low levels of support result largely
from flaws in the agency's peer review system. The system they
say is made up overwhelmingly of white researchers who
consciously or unconsciously dismiss proposals from minority
researchers.''
Last paragraph. ``NIH officials say that the peer reviewers
are not told the race of grant applicants but critics of the
agency say that the peer reviewers do not have difficulty
discovering an applicant's racial identity. I think the people
serving on the peer panels know the race of applicant by the
resume, the school, and then people make assumptions.''
I am wondering, Dr. Spiegel, since I know that you are new
to the department, are you aware of any of this data as it
might relate to your institute?
Dr. Spiegel. As the Chairman said, I have actually been
here for about 27 years in the department, so I can't evade
responsibility. I am painfully aware of some aspects of it. Let
me briefly respond. Within our intramural program, we have not
a large number of minority investigators. There are four, for
example, African-American tenured investigators, including one
that I personally mentored in terms of becoming tenured, and
another I alluded to who was appointed a Branch Chief. This is
a woefully low number in comparison to the percentage of the
population. Yet, sad to say, it is one of the highest numbers
among the NIH Institutes.
In terms of the general problem that you are talking about,
which relates to extramural investigators, investigators
applying for grants, I think that we have to address this in a
number of ways. I would turn to Dr. Kirschstein, not to
respond, but just to say that I know for all of her career at
NIH and certainly now in her capacity as the Acting Director,
she is a passionate advocate on this subject. She has launched
a strategic planning effort that I believe will address this
issue head on. I think under her leadership----if I can take a
moment, to express thanks to her for her mentorship of me as I
came in----the fact is that even with her commitment we cannot
guarantee success. The problem needs to be addressed, and
working with her, I believe we will do our best to address it.
Mr. Jackson. Thank you, Dr. Spiegel. By the way, I have no
doubt of Dr. Kirschstein's commitment. Thank you very much.
Mr. Porter. Thank you, Mr. Jackson.
Mr. Hoyer.
Mr. Hoyer. Thank you, Mr. Chairman. Dr. Kirschstein, I
would like to follow up on some of Mr. Jackson's questions. As
you have experienced, while while you sat at the table through
at least 3 or 4 directors, Lou Stokes and I have raised this
issue on a repeated basis over the last 2 decades. We have had
meetings in Congressman Stokes' office. I think we must have
had six or seven at least over the last 12 years. This is a
problem that is not only confronts NIH, but so many areas where
we have great difficulty. And try as we might, the unconscious
bias created by nonminority members participating in reviews
and basic research, it does have an impact. We know that.
I don't know what the answer is and I know Congressman
Stokes was frustrated as well. I think you sincerely have
addressed this issue. I refer to Dr. Kirschstein because it
really is, as you pointed out, an institute-wide problem.
Frankly, it is far beyond the Institute. My advice would be to
you, Dr. Kirschstein, and to Dr. Spiegel, to work more closely
with the minority members of the Congress. They have incredible
contacts around the country. They have incredible contacts with
young people, sons and daughters of their peers. Not Jessie's
peers, because Jessie is so young. Jessie's peers presumably do
not have 25- and 26-year-old young researchers ready to go. You
heard my point. This is almost an intractable problem because
when you look at the statistics that Lou Stokes and I started
with back in probably 1983 or 1984 or 1985, they have changed,
but not marketedly.
MINORITY MEDICAL STUDENTS AND LOAN REPAYMENT
Dr. Spiegel. If I may, I would interject one point. This
planning effort is in the President's budget, and it is
something that I am sure can be effective. It needs to be
monitored and tracked. I think there is a missed opportunity
here in terms of medical students. Since I started out my
career--maybe this is just sort of self-serving--having been
what I would characterize as a physician scientist, I know it
is something that we are in danger of losing. We have something
called the MARC program, Minority Access to Research Careers,
which NIDDK has strongly participated in. Again, I have had
several students in this program, both African-American and
Hispanic, over the years. The success has been that they have
ended up in medical school. Have they ended up in research? It
is not clear. Not everyone necessarily should end up in
research. But I believe that we have a desperate need for
physician scientists, for clinical researchers. I believe loan
repayment, which I believe is in the President's budget, could
be an enormous incentive.
Now, it is not just money that should be cast out there. It
would need to be tracked and evaluated, but I think loan
repayment is potentially a valuable approach. There are four
historically black medical schools. Clearly, the students there
are very bright people. Many of them should, as many of them
do, go back to serve inner city populations. That is very
important. But if we could recruit some of those medical
graduates into the ranks of physician scientists, this could
address part of the problem.
Dr. Kirschstein. I, of course, echoed that statement for
the last several hearings. I want to tell you what I did last
week, Mr. Hoyer, because I anticipated, perhaps without knowing
it, what you might say. I called Mr. Stokes, and as of this
Friday, he is going to be a consultant to NIH in regard to how
we increase the numbers of minority scientists we hire
intramurally as well as work on our programs.
CROHN'S DISEASE
Mr. Hoyer. I think that is spectacular. I really do. I did
not know that. I talked to Congressman Stokes about a month ago
before you talked to him. He is one of the most sincere,
thoughtful human beings I have ever served with in the State
legislature or here. He would be a wonderful addition because
he cares greatly about this problem. He cares about it in a
very constructive way and in a nonpolitical way. In terms of
insuring that we have the kind of feel that we need
intellectually, emotionally, viscerally, experience-wise, I
think will be very helpful. That is a great step. Thank you,
Doctor. I think, Jessie, that is a very positive step forward.
Let me try to sneak in one question on the subjects I had
down here. We talked about diabetes. I am not going to go
through those. I am going to submit some questions for the
record, which I think are sort of repetitive in some respects.
Let me ask you about Crohn's disease. In response to one of my
questions last year, I would like to discuss ongoing research
into the cause of a chronic inflammatory disease that affects
the digestive tract, also known as Crohn's disease. I
understand there is new evidence that suggest Crohn's disease
may be caused by infectious bacteria. Can you comment on that?
Dr. Spiegel. Let me comment briefly. There are certain
chronic diseases where a bacteria or other microorganism has
been suspected for years. The most recent New England Journal
included a report that a scientific team finally succeeded in
culturing a bacterium for something called Whipple's disease.
In the case of Crohn's disease, it has been long suspected, but
there is still no cogent evidence. It needs to be looked at and
I know that NIAID, under Dr. Anthony Fauci's leadership, is
actually specifically addressing this problem. We want to
cooperate with him. In terms of Crohn's disease, a type of
inflammatory bowel disease, we are definitely pushing forward
in terms of genetics and many other opportunities in terms of
both prevention and treatment.
Mr. Hoyer. Thank you, Doctor. I have other questions, but I
will submit them.
Mr. Porter. Mr. Wicker.
Mr. Wicker. Thank you. I will try not to take my full 5
minutes because I have another hearing.
Mr. Porter. Six, actually.
RESEARCH FUNDING ACROSS THE NATION
Mr. Wicker. Well, who knows. Where are you--how many
colleges and universities are participating currently in
diabetes research? Do you have any idea? We are farming it out
all across the country, undoubtedly.
Dr. Spiegel. When you say how many colleges and
universities, we certainly have investments in research in
diabetes throughout virtually all of the 50 states. If you are
asking about Mississippi specifically, perhaps none.
Mr. Wicker. Perhaps none there. You cut right to the chase
there.
Dr. Spiegel. I should say I haven't invoked my predecessor
yet but I believe he was from a small town in Mississippi.
Mr. Wicker. Indeed. I was going to suggest to follow up on
Mr. Hoyer and Mr. Jackson that in addition to Lou Stokes, that
maybe you hire as a consultant a former president of a very
small university in one of those states that doesn't typically
get the research dollars. I just want to say--and I think Mr.
Jackson and Mr. Hoyer will agree with this--we want the best
research done. We are not looking for substandard science just
so we can get economic development for our constituencies. But
it is a fact, and I would point out to you and I have mentioned
it to Dr. Kirschstein in several hearings, that the fact that
about half of the states receive approximately 90 percent or
more of the research dollars. And the other half of the states,
including my state of Mississippi, as you have already
mentioned, are left to fend for less than 10 percent of the
research money. I would like for you to get back to me on the
record as to the quality of the research that you have been
able to get from the smaller states, the F score type states,
if you will, that traditionally have not been the beneficiaries
of large research grants.
And because of that, perhaps there is an institutional bias
towards the large research universities. I would just like for
you to look at that and comment on the record as to the quality
of the research that you are getting, because I know that Mr.
Jackson wants minority research. And you know that I want
research conducted in the small states. But we want to have it
good research. That is the first priority. But if there is a
way to include us in this great experiment of your entire
agency, but particularly prevention of the disease of diabetes
or a cure for this dread disease, which I am personally
affected by, then we would like to participate. I would like to
have your comments on that, either today or on the record.
Dr. Spiegel. I will not give more extended comments in the
interest of time. But the only thing I would say is I know
about the IDEA program which is a version of the EPSCOR program
run by NCRR. I learned that NIDDK had not been participating.
This is something I want to evaluate very closely because I
think it is an opportunity. It is not a huge amount of money
necessarily, but this is one opportunity where we could support
research in your state. The other thing is I know that Dr.
Gorden, in his last period as NIDDK director, did join a group
visiting and looking into the Jackson heart study and other
things going on in Mississippi. I have met with Dr. L'enfant.
We are looking at a variety of areas of collaboration between
the 2 institutes because diabetes and heart disease are very
close. I think there may be some opportunities for NIDDK
involvement within that context.
[The information follows:]
NIDDK Support for the 20 States Receiving the Least NIH Research
Funding
The list below summarizes the NIDDK support provided in 1999 for
sixteen of the twenty states receiving the least research funding from
the NIH. We awarded 198 projects for a total of approximately $44.1
million. Missing from the list are Alaska, Idaho, Mississippi, and
Montana, which did not receive any NIDDK research support in 1999. Also
missing because of a lack of research support from the NIDDK in that
year is Puerto Rico, whose scientists are eligible for NIH support.
These grant proposals competed against those of scientists from all
of the other institutions and states, and each succeeded in achieving a
percentile ranking which placed it within our payline. The science
supported is of equal quality to the other projects supported by NIDDK
programs. The more fundamental problem is how few proposals are
received from scientists in these states.

Dr. Kirschstein. Maybe I could add something, Mr. Wicker.
As you know, Dr. Gorden and I did visit your fair state. We do
have some grants at Millsaps College. We are very pleased by
that. I hope that the next time we can go we can visit Millsaps
in addition to the University of Mississippi. We have been
working with the school of pharmacy at Oxford which has a
larger grant portfolio right now than does the medical school,
a fact that quite surprised me. We have been working with
members of the faculty of the school of medicine who have been
coming up to learn about opportunities and we hope we can add
to their grant portfolio.
Mr. Wicker. Thank you very much. I would just say, in
conclusion, that I think you know of the tremendous support
that you have in this subcommittee led by our chairman. We
certainly want to be helpful and we want to look forward to the
day when your coming before us and say we have phenomenal
results in the prevention and treatment of this disease.
Dr. Spiegel. I appreciate that support. Thank you.
Mr. Porter. Thank you, Mr. Wicker.
Mr. Cunningham.
STEM CELL RESEARCH
Mr. Cunningham. Thank you, Mr. Chairman. I have a question
and I have got a direct purpose in asking it. My own personal
beliefs are pro-life and I don't believe in supporting taxpayer
funding for abortions. Saying that, I support stem cell
research and Dr. Larry Goldstein at UCSD has worked with my
daughter in research areas. An issue has come up. Instead of
using potent cells, I understand that you can pursue the same
kind of research from umbilical cords or other stem cells, but
the research, as I understand it, is different. Can you
elaborate on why we need to do both on that? I support stem
cell research. I would tell if you, I have had a child like I
have met that had to take blood samples 5 times a day, and I
have seen these parents that they don't know if their child is
going to live--or in the future the potential damage that the
disease could cause, I would do anything, anything, including
stem cell research. I would try to put myself in those parents'
and children's shoes. But I also feel that if we do this within
the government, then many of those moral and ethical values
that many of us hold, not saying pro-life have all ethical or
moral values, but generally, I think that a lot of those
concerns would be met in government involvement where they
wouldn't otherwise. My real concern is for the funding of the
diversification of the research itself.
Dr. Spiegel. I would respond to that, first, by saying I
obviously respect your personal views, and those of Mr. Dickey,
who is not here. I have heard his views on the subject and
those of many others. It is clearly a very important subject
that a wide diversity of Americans could differ on. Having said
that, it is clear that type 1 diabetics, as well as people with
spinal cord damage, Parkinson's disease, and many other
diseases, stand to benefit from research in this area. Let me
just confine my comments to some technical ones. Every cell has
all of the genes in the human genome. When we are talking about
these stem cells of various kinds, we are talking about ones
that are on a spectrum from those that are capable of
activating every one of those genes: so-called toti potential
or pluri potential stem cells to others that can activate only
a subset of cells. Studying pluripotent stem cells can address
new kinds of questions that studying the others can't. At the
same time though, what you are referring to, cells from the
umbilical cord, are hematopoietic stem cells. The ones that I
refer to in this recent diabetes development are pancreatic
duct cells that can then turn into insulin-secreting beta
cells. It is clearly very important to study those that are
further along the path of differentiation. We can learn a
tremendous amount. Let me just leave it at that.
HEPATITIS C
Mr. Cunningham. In the other questions they talk about,
maybe we don't fund certain research. I wouldn't want the job
of deciding precisely where the research goes. I don't think
Members of Congress ought to do it. I don't think that the
President ought to do it. I think it belongs in the hands of
the professional researchers to see where the science is taking
us, if there is any overlap.
Another disease that is becoming at least maybe just my
awareness more and more prevalent, Rolf Benerschke, who used to
kick for the San Diego Chargers, has hepatitis C. He got it
through a blood transfusion. Many of the hemophiliacs have come
to me in the district, and not only did they pick up HIV, but
hepatitis C. Do we have, from NIH perspective, hope in the
areas of hepatitis? I look at Rolf Benerschke and people like
that, and it is tearing his families apart. I haven't heard of
any specific research in that direction.
Dr. Spiegel. There certainly are important advances there.
First, with regard to the issue of transfusion, due to the
epidemiologic efforts of the CDC, NIH and others, we really do
feel that new infections attendant to blood transfusions should
no longer happen and they have not perhaps since 1992. But in
terms of patients who have the disease, in terms of treatment,
the combined agents that I referred to, interferon and
Ribavirin, are able to actually clear the virus from as many as
40 percent of people who are infected. We need to do better
than that. We are launching this year a multi-million dollar
major clinical trial called HALT C, which will look
specifically at longer, more intensive treatment with
interferon and other agents to see if we can improve on that.
I mentioned African-Americans who have a disproportionate
burden of Hepatitis C. It turns out not only is there a higher
incidence in terms of African Americans, but there is also a
reduced response to treatment. One initiative we are planning
is to explicitly enroll African-Americans in the trial to look
at the reasons why they don't respond, in order to develop
better treatment. The other point that needs to be made though
is prevention, and the possibility of a vaccine. This is being
worked on intensively both in the intramural labs of NIAID and
NIDDK as well as in other labs.
Mr. Cunningham. I would also like to add my support of most
of the people that I respect. On the other side of the aisle,
Lou Stokes is one that I think is very well respected from his
professionalism and what he could do for NIH. I know I
personally laud that decision.
I want to couch this next thing very carefully and I would
like Jesse to listen. I am not being partisan, not even one
ounce of it. But I want you to understand maybe where I am
coming from. Quite often Republicans talk, I think, too often
without thinking about what the results are. For example, if I
say I am against bilingual education, there is a certain group
of people that think I don't care about them, that they can't
learn. If I say I am against affirmative action, there is a
group of people that say ``well, Duke doesn't care about us.''
I think we have done that too much in some cases, at last until
we come forward and say we have a better plan to affirmative
action or bilingual education or many other areas.
And in line with Mr. Jackson's comments, I had--I know at
one time I heard that for example black pilots weren't as good
as white pilots. All you have to do is look at the Tuskegee
airmen and see what their record was given the chance. I had an
African-American pilot who was my operations officer. He could
hold hands with anybody. We had a spot open in the Blue Angels.
His name was Donny. I can't remember Donny's last name, but he
hadn't had a chance to fly the A-4, and I had him in my
squadron, so I let him fly just so he could compete. And he
won. But with affirmative action, and I know I have heard many
people talk about it, I think there is a better way than
affirmative action. I really believe that. I know it is a big
political issue, but I am not being political here. For
example, I went the other day to see if I could have keratotomy
done with surgery. The doctor came out and he was African-
American. Some wonder if that doctor got in his position
because of affirmative action, or could one have gone to a
doctor that had more quality, but that individual was there
because of affirmative action. I guarantee he wasn't because he
is a very noteworthy doctor, but there is a perception out
there in many of these cases that I think in some cases is
taking place, especially in the higher skilled areas. I think
the answer to concerns about affirmative action is education to
make sure at the beginning that we don't have those disparities
or those incorrect perceptions that exist. As we go forward in
medical research like Mr. Jackson requests, I hope that those
kinds of things are split apart, because I have met some very
fantastic doctors from diverse ethnic backgrounds, not just
African-American, but Asian as well.
I would also hope that would extend, since my daughter
plans on getting an M.D. Ph.D., that that goes along with women
scientists as well, that we don't have a perception that a
woman maybe can't perform as well as a man. I want to tell you,
my daughter is going to kick rear end when she gets up there. I
hope all of those opportunities--and I support the line that
Jesse was talking about as far as the actual research in it.
Thank you.
Mr. Porter. Thank you, Mr. Cunningham.
Mrs. Lowey.
TYPE 1 DIABETES TRIAL NETWORK
Mrs. Lowey. Thank you, Mr. Chairman. And I want to thank
you, Dr. Spiegel, for your presentation for all of the good
work that you are doing, and Dr. Kirschstein, it is also a
pleasure to see you. I want to welcome Bruce Siegel, a
constituent, a downstate leader in JDF. Nice to see you here
today.
Dr. Spiegel, Mr. Bonilla asked you and you referred in your
testimony to the pilot studies network for type 1 diabetes. How
would that coordinate with the NIH clinical trial web site that
was just announced? Would your network be helpful to families
or more targeted towards researchers and physicians?
Dr. Spiegel. They should coordinate very well. I think that
you are about to hear from NLM, so I am sure you will hear
about the clinical trial web site. The intention is to be
certain that every NIH-supported trial is listed there. It will
be accessible in a way that will provide links for primary data
from the published literature for physicians, and information
that is patient-friendly as well. So the trials that we are
contemplating would certainly be represented there.
INTERSTITIAL CYSTITIS
Mrs. Lowey. I know that we talked about stem cell research.
I also want to follow up on my colleague, Rosa DeLauro's
question about IC. I have several constituents, one a good
friend, who suffer from IC. And I understand that NIDDK is
planning an epidemiology study on IC and that there are
meetings to develop this study in April. Are you going to be
doing them? Attending them? How long will the study take? How
much money would be committed? Could you explain?
Dr. Spiegel. Yes, just very briefly. I would say that I
have met with Vicki Ratner, who is the head of the Interstitial
Cystitis Association. I will be meeting on March 27 with
Deborah Slade, who is head of the National Bladder Foundation.
We are looking for input, as I alluded to earlier, from all of
our constituency groups. There has been some delay I am aware
of in launching this epidemiology study but we are committed to
it and we will do it in the best possible way and as quickly as
possible.
INFLAMMATORY BOWEL DISEASE
Mrs. Lowey. One last question before I yield a little of my
time to my good colleague, up to a million people in America
suffer from inflammatory bowel disease. In the committee report
last year, we encouraged the NIDDK to support basic
investigations that were outlined in challenges and IBD, a
document assembled by the scientific community. Is there any
progress being made on this? Could you discuss it with us?
Dr. Spiegel. Yes. Very briefly, on March 10 we are going to
be holding, as part of our digestive disease interagency
coordinating committee, a meeting on the genetics of
inflammatory bowel disease. This is, again, a complex genetic
disease, but it offers some opportunity for progress. There
have been important advances in Crohn's disease with the use of
a monoclonal antibody that can treat a certain significant
subset of the patients. That grew out of NIDDK-supported work
on an animal model. It is important to be aware of that. Of our
12, soon to be 13, digestive disease centers, several are
committed to studies of inflammatory bowel disease. We are also
spurring even further developments in this field in the
intramural program as well, with NIAID.
Mrs. Lowey. Thank you very much. I appreciate your
important responses and the fact that you even spoke like a New
Yorker, so I would have time to yield to my good friend, Jesse
Jackson.
MINORITY INVESTIGATORS
Mr. Jackson. Let me thank the gentlelady for yielding. I
want to offer some clarity in the strongest possible language
that I can possibly offer. I offer to my good friend on the
other side of the aisle, Mr. Cunningham, and Mr. Wicker, who
departed earlier. I want to make it very clear what the context
is. Because of the coordination problem on these disparity
issues which continue to get worse, and because of your
consistent increase request in your budget, as a member of this
body, I have some very legitimate questions about the road and
the path that this research is taking, particularly the
resources for this research. It just happens to coincide with
the dearth, if you will, or the absence of a number of minority
researchers who could be pursuing this research if, in fact,
NIH as an institution were open to that. My colleague a few
minutes ago said that he doesn't believe that these decisions
should be in the hands of Congress, he doesn't believe these
decisions should be in the hands of the President, but
presently in the hands of professional researchers which he
presently supports.
There are enormous disparities in every institute across
the NIH. That is what I am seeking to address with H.R. 2391
which is a bipartisan bill that has Mr. Norwood on it, it has
J.C. Watts on it, and a number of other prominent members of
your party who recognize that what I am trying to do to address
these questions to a single center at the NIH who would be
responsible for that coordination across the entire institute,
who will keep me every year from having to ask various
institute officers and directors the same questions, because I
will be able to drill one person, whose responsibility it will
be to bring me the information back at every one of these
appropriations hearings.
But I want to be clear about one thing that I have begun to
determine and pick up in this committee. Quite frankly, it is
something that I am beginning to resent. Ever since I have been
asking these questions across the center, some of my colleagues
have offered almost a caveat to every one of their statements
that somehow the researchers that I am talking about, those
African-Americans with medical degrees and Ph.D.s are extremely
qualified people, that somehow there is always this caveat. I
know Congressman Jackson, for example, doesn't support
substandard research. Somehow my arguments about better
coordination about the NIH happen to be tied to affirmative
action. I have never mentioned the words ``affirmative
action.'' I am talking about the $18,000,000,000 that we spend
at NIH that presently is not being coordinated across the
minority research community, and I assume that researchers use
fundamentally the same methods to be able to test research so
that people can test their evidence against other research and
be able to make determinations about that.
But the fact that Members of Congress even refer to my
efforts and my questions across this committee as somehow being
supportive of or even adding to the conversation that I am
having as substandard research, or somehow affirmative action
related or some special program for minorities in these
departments is precisely, Mr. Chairman, the problem that exists
in this Congress. But beyond that, if the same culture that I
am most worried about at NIH exists, that somehow in our effort
to reach out to minority researchers or to find minority
researchers or women researchers or Asian American researchers
or Native American researchers, if there is such a culture that
exists at NIH that suggests that their research is inferior
based upon some of the questions that my colleagues have
attempted to reduce my questions to, this is precisely what I
am going at at NIH, and that is what I am trying to do with
this bill----
Mr. Cunningham. If the gentleman would yield, I hope you
understand I was saying that in support of your position.
Mr. Jackson. I appreciate that. Let me reclaim my time.
Whenever I sit here and listen to a lot of big words that end
in ``ology'' and ``ism'' from a lot of different directors and
listen to all of their very sophisticated analysis of what has
transpired over the last year before they came and asked our
committee for 3 more billion dollars or an increase of 6
percent, at no point in time does anyone ever question their
research, at no point in time, not from cancer, not from
diabetes, not from any of the institutes.
But when I talk about minority researchers, the first thing
someone mentions over there is substandard as if the same tests
that are used for those researchers would fall under some
different standard than the research that I am talking about or
something associated with affirmative action or somehow not in
the hands of Congress when we have responsibility and oversight
for the money of this institute and there is documented data--
he says he has been there 27 years and still feels bad about it
because he knows there is a dearth of researchers.
Mr. Cunningham. If the gentleman would yield, the point
that I mentioned wasn't a negative. It was the fact that I was
trying to point out that given a chance that it wasn't
affirmative action. I was speaking on the other side--oh, it
was Donny Cochran that went with the Blue Angels. There is a
perception out there which is not true. That is why I was
trying to use that as an example. Not as a negative that you
took it----
Mr. Jackson. Reclaiming my time, I respect the gentleman.
The gentleman knows that he and I have a great personal
relationship, nor am I trying to suggest or use the platform
today. Anything I have to say in private to the gentleman, the
gentleman knows that I will handle it. But I want to be really
clear that even having a conversation as being couched about
the questions that I have been raising about NIH to suggest in
any way, shape or form, there is a trailer of affirmative
action associated with it or some special interest center that
need to be created or associated with it or some substandard
research that is associated with it, the fact that that is even
associated with my line of questioning, which has absolutely
nothing to do with substandard research, I deeply resent that.
I want to make it clear for the record so my colleagues and
some of the staff when they go back to their various offices,
when they come back next week and we talk to other institutes
do not associate those terms with the line of questioning that
I am raising at the NIH because I want answers to my questions
and they have nothing to do with substandard research. I thank
the gentleman.
Mr. Hoyer. I would like to make a comment, if I can.
Mr. Porter. Mr. Hoyer.
WOMEN IN CLINICAL TRIALS
Mr. Hoyer. One of the things that concerned this committee,
about 10 years ago--Mrs. Lowey, would you wait one second--was
when we found out the very low number of women in clinical
trials, even on diseases that mostly affected women. So what
Mr. Jackson is talking about he is correct, Duke. This is not
affirmative action, but a recognition what we need to do in
order to get good answers. That is what he is talking about.
And the failure to include--I was appalled when we heard at the
low number of women--I am sure you were, too, Dr. Kirschstein--
the low number of women in clinical trials. It was incredible.
I don't know whether you were on the committee at that point.
John, you remember it. And we all said, ``How can you do
that?'' I don't think it was an effort to discriminate against
women per se, but there was a lacking in consciousness of the
impact of the cohorts in the research groups. So I think that
is what Mr. Jackson is saying.
Mrs. Lowey. In fact, as long as my colleague asked me to
remain, if the gentleman would yield just briefly, I do
remember that, Mr. Chairman, when including women in the
clinical trials--and Dr. Kirschstein probably remembers--made
them too complicated. This is what we were told, that it would
just complicate the studies. At that time even the rats were
all male.
Mr. Hoyer. We won't go into that last comment, thank you
very much.
TYPE 1 DIABETES
Mr. Cunningham. This is just one of those children that has
diabetes that I was talking about. You can see that she is an A
student, she is a doll. She looks like she just stepped out of
Saks Fifth Avenue.
Mr. Hoyer. I can't from here observe that she is an A
student, but I can certainly observe that she is a doll.
Mr. Cunningham. Her name is Sara.
Mr. Porter. Sara, welcome.
Mr. Cunningham. This is her diabetes bear. She wouldn't
give it to me.
Mr. Porter. We are pleased to be joined by our colleague
from Washington, not a member of our subcommittee, but the
cochairman of the Congressional Diabetes Research Caucus and a
man who has provided tremendous leadership and strong pressure,
as I am sure Dr. Spiegel is aware, for increases for research
into this dread disease. Our colleague, Congressman George
Nethercutt. George.
DIABETES RESEARCH WORKING GROUP
Mr. Nethercutt. Thank you, Mr. Chairman, and I appreciate
your indulgence and the indulgence in the members of the
subcommittee in allowing me to join here for a few minutes just
to say hello to Dr. Spiegel and certainly welcome you, sir. I
know that you have energized the institute already. Dr.
Kirschstein, I am so happy to see you and Mr. Laurence and
others who have been so much a part of this effort that affects
so many in this country. And is indiscriminate in its impact on
men, women, people of all races, religions--disproportionately,
I might add, on the minority populations in our country. It is
in our national best interests, it seems to me, to cure this
disease.
Dr. Spiegel, I welcome you, sir, and all of you here who
are dedicated to this the same thing, in my judgment. I want to
ask just a few questions as it relates to the actions that the
Congress has taken and that the caucus, the Diabetes Caucus,
has taken in the House. We have so many people who are members
of it representing both parties, obviously, and all regions of
the country. It is a wonderful bipartisan effort to focus on
this disease that has such tremendous impact on our economy and
human health.
Dr. Spiegel, I know that you are aware of the Diabetes
Research Working Group Report. This subcommittee and this House
and Appropriations Committee has graciously put in the funding
early to conduct the research and impanel the people to come up
with the report. And it is a good report. It is comprehensive.
I would just ask, sir, if you in your position and in your
responsibilities would feel encouraged about the
recommendations of the Diabetes Research Working Group Report,
and what approach you might recommend to this committee for its
implementation.
Dr. Spiegel. First, I appreciate your being here and I
appreciate your leadership in this very important issue. I
absolutely am in accord with and view the DRWG as just the kind
of planning process we need: with community input, public
input, and expert scientific input. The five extraordinary
areas of opportunity are ones that are right on the mark, and
the specific areas of complications and other kinds of targeted
interventions are critical. We are trying within the context of
our existing budget to meet those recommendations as nearly as
possible. I could get into very detailed budget specifics, but
what I would say is fiscal year 2000 is a difficult year for us
in that regard. We have a huge noncompeting growth of $105
million in the research project grants mechanism. That limits
our flexibility. Nonetheless we are aiming for at least a 2-
percentage-point increase greater than our appropriation
increase for diabetes research using those recommendations. At
the same time I believe that diabetes clearly is a disease that
affects every organ system, and every NIH institute needs to be
and is involved. I am meeting with each of the institute
directors and meeting with Dr. Kirschstein as well. This is a
point that I have driven home and I believe there are obvious
areas of shared interaction with the NIAID vis-a-vis type 1
diabetes, and with the NHLBI vis-a-vis the cardiac
complications. I hope in that respect that we will be able to
stimulate substantially the effort across NIH.
DIABETES--HEALTH AND ECONOMIC BURDEN
Mr. Nethercutt. I appreciate that. I think those of us who
are eminently involved with this whole subject are looking for
a commitment on the part of NIDDK and NIH to allocate in such a
way that we look at the dollar figures as it relates to the
institute opportunities. And our hope is and expectation would
be that there would be a push to try to have the dollars follow
the disease and the impact of the disease. We think--we, I will
speak for myself and others I think who share this view--that
because diabetes has such a disproportionate impact on our
health condition in this country, productivity costs are
staggering, the Medicare costs are staggering, that is it is in
our national best interests and NIH's best interests to
recognize that and seek to have an application of funds that
recognize that disproportionate impact of diabetes on our
society. Is that something you can accept, adopt, would push
for without pinning you down too much? We have a research
working group recommendation on an annual basis over a period
of time that we aren't meeting. I am wondering to what extent
you feel that it is in our best interests to meet those
recommendations and what you intend to do about it.
Dr. Spiegel. I have to be perfectly candid. The
recommendations in terms of scientific opportunities are ones
that I totally embrace. I will do everything within the budget
context that I am given to reach those. We are taking very
concrete steps both in NIDDK and in terms of leadership across
the NIH to try to increase diabetes spending. At the same time
I would have to be candid and say that if one looks at the
target figures--actual numbers given in what I consider a
professional judgment budget--there isn't flexibility within
our existing budget envelope to allow us to reach those
figures.
DIABETES RESEARCH FUNDING
Mr. Nethercutt. Would you want this committee or the
subcommittee or the House and the Senate to reconfigure the
figures so that it would be easier to reach the goals that you
think we might seek?
Dr. Spiegel. You are putting me on the spot. I want to give
the best answer that I can to that--and I want to be mindful of
what the DRWG report said. The chairman of that group is
someone I met with very recently, and we had extensive
discussions about this. The DRWG report did point out that it
did not recommend detracting from the other very important
diseases within the NIDDK mission. We don't want to do that.
Given the opportunity to get additional resources, yes, we
would be able to move faster, and we would be able to move down
multiple paths. We would be able to put in the infrastructure
that would enable further hypothesis-driven research. So
certainly that would be very welcome, but on the other hand, I
am prepared to do the best I can within the existing budget
context.
Mr. Nethercutt. This subcommittee and the chairman of the
subcommittee have been extraordinary in terms of recommending
additional funding for NIH for this effort to increase funding
for biomedical research. It is a marvelous undertaking and it
is very difficult in this particular subcommittee and such a
tough one with lots of good reasons to spend money. So this
leadership here, Mr. Hoyer, Mr. Porter and everybody else has
been extraordinary.
I would close because I know I am out of time. I have
questions, if I may, Mr. Chairman, submit for the record,
submit and seek your responses. And also offer, sir, to work
with you and everyone at NIH and NIDDK most particularly to
figure out ways we can hasten the cure of this disease and the
research potential that is out there for the cure of this
disease. Those of us who are involved in it feel absolutely
confident that we are on the edge of a breakthrough and relief
for the 16 million people and the next generation of Americans
who are going to be affected by this and people around the
world as well. So I hope we can work together and try to make
this happen.
Dr. Spiegel. I really look forward to working together and
seeing you in another context.
Mr. Porter. Thank you, Congressman Nethercutt, for being
with us. First of all, let me say to Dr. Spiegel, you handled
all of those questions very good. They were all real easy. Next
time when you come we will think of some really tough ones.
Thank you for the fine job you have begun to do there and
have done there for many years prior to becoming Director. We
do look forward to working with you, and I would say to my
colleague from Washington, we are just as anxious as he is, and
you are, to get the resources that you need to reach the goal
of the working group and go down the multiple paths and see if
we can't provide those kinds of research. We obviously can't do
it in one year or maybe even two, but if we set it as our goal
and keep working toward it we can get there, and sooner rather
than later. So thank you for the fine job you are doing. Thank
you for answering all of our questions.
Dr. Spiegel. Thank you very much.
Mr. Porter. The subcommittee will stand briefly in recess
and then we will hear the National Library of Medicine.

the record:]

NATIONAL INSTITUTE OF ARTHRITIS AND MUSCULOSKELETAL AND SKIN DISEASES
WITNESSES
STEPHEN I. KATZ, DIRECTOR, NIAMS
STEVEN J. HAUSMAN, DEPUTY DIRECTOR, NIAMS
MARGARET S. KERZA-KWIATECKI, ASSOCIATE DIRECTOR FOR MANAGEMENT AND
OPERATIONS, NIAMS
ROBYN J. STRACHAN, BUDGET OFFICER, NIAMS

DENNIS P. WILLIAMS, DEPUTY ASSISTANT SECRETARY, BUDGET, DHHS
Introduction of Witnesses
Mrs. Northup. Good afternoon, welcome. We're going to begin
the afternoon's hearing with the National Institutes of Health,
National Institute of Arthritis and Musculoskeletal and Skin
Diseases. Dr. Stephen Katz is with us today. Thank you, Dr.
Katz, and welcome.
Dr. Katz. Thank you very much, Mrs. Northup.
May I introduce the people at the table? To my far left is
our Associate Director for Management and Operations, Ms.
Margaret Kerza-Kwiatecki; the head of our Budget Office, Ms.
Robyn Strachan; the Deputy Director, Steve Hausman; and of
course, you know the Acting Director of NIH, Ruth Kirschstein,
and Mr. Dennis Williams from the Department.
Statement of the Director
I'm honored to appear before this Committee today. As
Director of the National Institute of Arthritis and
Musculoskeletal and Skin Diseases, I'm acutely aware of the
everyday lives of American people that are enormously improved
by the research that our Institute supports. Children on the
playground, women and ethnic minorities affected by so many of
our diseases, particularly autoimmune diseases, adults in the
workplace, elderly Americans striving to live independently--
their lives are enhanced or compromised by the health and
functioning of their bones, joints, muscles and skin.
I want to express my appreciation for the Fiscal Year 2000
appropriation. It enabled us to invest in medical research with
much greater depth and breadth than ever before. I want to
share some examples of advances and opportunities, and also
talk to you about our commitment to addressing health
disparities in all areas of our mission.
CLINICAL RESEARCH
The focus of my remarks today will be on clinical research.
The ultimate goal, of course, is to improve health through the
translation of basic research findings. Some of these research
findings include the finding that low dose estrogen, in
addition to calcium and vitamin D, can prevent bone loss. New
therapies have been developed for rheumatoid arthritis. The
bases for these new therapies were all supported by the NIH and
the National Institute of Arthritis and Musculoskeletal and
Skin Diseases.
New findings tell us that normal hair growth is controlled
by newly identified genes. These genes produce proteins that
then form the targets for new therapeutic interventions.
MUSCULAR DYSTROPHY
Research has revealed that a common antibiotic, gentamicin,
may be useful in the treatment of Duchenne muscular dystrophy,
a disease which is due to a genetic mutation. And with this
antibiotic, you can overcome this mutation or so-called stop
codon in the gene and have the gene produce a normal protein.
This has been shown not only experimentally, in a cell culture
situation, but also in experimental animals that have the
disease.
Also in gene therapy, muscular dystrophy, there's another
disease called limb-girdle muscular dystrophy. This is a
muscular dystrophy in which there is a mutation in a gene that
encodes for a smaller protein; that may be an excellent target
for new therapies. We are studying mice that have this
particular disease, another very important advance.
OSTEOPOROSIS
And another very exciting, very recent advance shows us
that new drugs or old drugs, as well as recently identified
hormones, can be very important in terms of the treatment for
osteoporosis. So let me give you a couple of examples. The
statins, for example, which are commonly used drugs to lower
cholesterol, have been shown to have a profound effect on bone
formation. As well, leptin, which is a hormone that's produced
by fat cells in the body and that controls obesity, has also
been shown very recently to control bone growth. Two very
exciting findings that I'm sure will yield to important new
scientific discovery.
CLINICAL RESEARCH
Through our generous appropriation in Fiscal Year 1999, we
launched a number of studies that I am sure will yield valuable
information. I want to briefly highlight seven new studies
we've initiated. Again, the focus is on clinical research. The
first is a study in osteoporosis in men. We established a
multi-center consortium to look at risk factors for
osteoporosis in men, clearly an underserved area. We've
initiated studies that assess combination drug therapies for
osteoporosis; two drugs from different companies are used in
combination. These are the types of studies that would not be
supported by the pharmaceutical industry.
We initiated a large, multi-center study which addresses
surgical versus non-surgical interventions for low back pain.
We also initiated many pilot studies in rheumatic and skin
diseases. These are pilot studies of therapeutic interventions
that include new treatments for leg ulcers, scleroderma, lupus
erythematosus, and rheumatoid arthritis.
One component of our pilot trials was the autoimmunity
initiative. These are funds that were added in addition to the
appropriation last year by the Congress. The NIAMS received had
an additional $4 million for new research on autoimmunity that
enhances and strengthens our current portfolio of research in
this area.
FIBROMYALGIA
Another area of growth in Fiscal Year 1999 was our
commitment to 15 new grants in the area of fibromyalgia. And
these grants will cover areas from behavioral to genetic to
early interventions in disease. They also will identify new
opportunities for research.
We've also started a network, a gene searching expedition,
in the area of the spondyloarthropathies, which is an
inflammation of the spine, with the American Spondylitis
Association being a true partner in this consortial
arrangement.
Finally, we have continued our commitment to clinical
research training and career development. And in this area we
went well beyond our initial commitment and funded numerous
awards in many of our research areas.
Through our Fiscal Year 2001 planning process, we've
identified needs and opportunities that we will pursue. These
are, for example, in osteoarthritis, in scleroderma, in skin
gene therapy, in arthritis of the spine, in muscular
dystrophies as well. And in this latter area, we have two
meetings scheduled for May--one in the area of Duchenne
muscular dystrophy, with the Parent Project--as well as one in
fascioscapulohumeral dystrophy with the FSHD Society. These
workshops are being developed along with our colleagues in the
National Institute of Neurological Disorders and Stroke, as
well as with the NIH Office of Rare Diseases.
HEALTH DISPARITIES
In the area of health disparities, we've taken a multi-
pronged approach. With regard to research, there are a number
of diseases that affect minorities disproportionately. We
intend to help correct this disparity through our significant
investment in these diseases, including lupus erythematosus,
scleroderma, osteoarthritis, and vitiligo, which is a skin
disease in which individuals lose pigmentation from their skin.
It affects majority light-skinned individuals as well as dark-
skinned individuals, but psychologically, dark-skinned
individuals are affected to a much greater extent. Keloids,
which is an overgrowth of scar tissue, affects minorities
disproportionately, particularly African-Americans.
We also have a new scientific director at the Institute,
who has initiated a new health partnership program including a
diversity outreach program with the greater DC community. We
hope to use this as a launching pad for a national initiative
in this area.
We've also expanded our information dissemination programs
to include materials for Spanish-speaking people, as well as a
new toll-free line in Spanish and English. We've also had
discussions with leaders at HBCUs as well as developed new and
enhanced programs for scientists at HBCUs as well as at
Hispanic intensive institutions.
Mrs. Northup, the President's budget for the National
Institute of Arthritis and Musculoskeletal and Skin Diseases is
$368,712,000, and I'm happy to answer any questions that you
may have.
Thank you.
[The prepared statement follows:]
LUPUS
Mrs. Northup. Thank you, Dr. Katz.
I think I'll start right where I left off last year,
questions about lupus. You talked about the gene therapy in
your presentation. I'd like to go back to the gene therapy,
because I guess it's something I don't understand, both how far
away solutions might come, who would benefit from it, in terms
of, are there people that already have lupus, or would there be
people that we would test that would be predisposed to it,
where we would think maybe we could intervene before that
happened.
Dr. Katz. The area of lupus is not the area that we're
particularly focusing on in terms of gene therapy. There's not
enough known.
Mrs. Northup. You talked about the chromosomes. I guess I
just assumed that that was----
Dr. Katz. Actually, you're right, I discussed it in some
detail last year, in terms of our commitment to identifying
susceptibility genes in lupus. Lupus is clearly not a single
gene mutation disease. Undoubtedly, there are many regions in
the genome that help predispose individuals to lupus
erythematosus.
What we're trying to do with our investment, large
investment, actually, in many centers around the country, is
identify those genes that increase the susceptibility of
individuals to lupus. Once we identify those genes, that's only
the first step. The second step is to find out the function of
those genes. Once one finds out the function of those genes,
one can try to interfere or somehow promote their activity.
Mrs. Northup. And would that be done for people that
already have developed lupus, or to protect people from
developing lupus?
Dr. Katz. Of course, the ultimate would be in prevention.
But one would have to identify very strong susceptibility genes
if one were going to try to intercede in that area. I would
imagine that prevention would not be in the area of gene
therapy, but would be much more in the area of conventional
therapeutics or biologicals.
Mrs. Northup. So then the benefit would be, once you
developed it, you would intervene somehow. I have to admit,
understanding what you do to intervene, I'm not sure whether
you're talking about a pharmaceutical intervention, whether
you're talking about some sort of transplant, whether you cause
some mutation. Can you help me with what sort of therapy we're
talking about?
Dr. Katz. Yes. I would say the answer to that is yes, yes
and yes. Because it includes all those possibilities.
Ultimately, the goal really is to try to identify increased
susceptibility to disease and identify the reason for the
increased susceptibility. And ideally, we want to prevent in
some way or somehow mask that susceptibility.
That would occur in people who tend to be more susceptible
to lupus erythematosus. We're trying to find out who is more
susceptible to lupus and why. We know that it occurs in women
to a much greater extent than men. We know that it occurs in
the Hispanic and African-American populations to a much greater
extent. We're trying to find out why.
Once the disease occurs, and is identifiable, we try to
identify who's susceptible for more severe disease, who is
susceptible for less severe disease. It covers a broad spectrum
of disease. Those people who are more susceptible to the kidney
disease may get much stronger therapies early on, because that
will obviate their getting disease later on.
Mrs. Northup. Well, where I'm trying to go with this, I
guess my interest is, how clearly do we know where the path is
going to take us. It sounds like it's a wonderful path, but
we're not sure where the path is going to take us or how fast.
So what today are the most promising investments that you're
making in trying to relieve the effects of lupus?
Interventions, I know there's no cure.
Are there any possibilities outside of the gene therapy or
chromosome, where there are cures? If they're not cures, are
there much better abilities to manage it? And how close are we
to finding those? What is the level of our investment we're
making in that?
Since the gene, and again, I have to say, I'm not opposed
to investing in long-term gene therapy. It just seems like
we're becoming so fascinated with that that we're not maybe
funding or trying to address today's need.
Dr. Katz. Let me answer that by providing a perspective in
terms of lupus erythematosus. You know the clinical center that
we have on the Bethesda campus is charged with doing a lot of
clinical studies. Well, one of the major advances in lupus
erythematosus came about because of a very long-term investment
in a research project that dealt with treatment of people with
lupus nephritis. Lupus nephritis is one of the main causes of
death of patients with lupus.
This study began in about 1987. It ended in 1997, and the
data are still being looked at. It has clearly changed the way
rheumatologists and nephrologists think about treating patients
with lupus erythematosus. The treatment is high dosage
cyclophosphamide, which is a drug that interferes with the
immune system, in addition to prednisone. Prednisone alone is
helpful, but prednisone alone has many, many, many side
effects. Cyclophosphamide has side effects not quite as severe.
So the whole treatment of lupus was changed over those
years, because of the investment in the intramural program at
the NIH. People approach patients very differently nowadays.
We continue those investments in terms of developing new
therapies with fewer and fewer side effects. In addition, we
know much more about the immune system. We know some, not all,
about what causes some of the autoimmune reactions. We at least
know how cells interact. And I will tell you that some of the
most exciting work that's going on now in lupus erythematosus
tries to block cells from interacting with one another, because
we know a lot about the molecules that sit on cells.
We have funded much of the fundamental research that now is
being addressed by many pharmaceutical companies to try to
block that interaction so that this cell of the immune system
doesn't kill this cell of the skin, this cell of the central
nervous system, this cell of the kidney, which are all affected
in lupus erythematosus. So it's really a multi-pronged
approach. It is not only from a more fundamental, long-term
approach, but also for the here and now.
Mrs. Northup. Okay. Thank you.
Mr. Jackson.
LUPUS
Mr. Jackson. Thank you, Madam Chairwoman.
Let me thank you, Dr. Katz, for your testimony today and
for your work at NIAMS. The President's fiscal year request is
$363.5 million, an increase of $19 million, and a 5.5 percent
increase over Fiscal Year 2000. Included in this total is $9.5
million targeted to the following NIH priorities: new
approaches to pathogenesis, $5 million; new avenues for
development of therapeutics, $2.5 million; genetic medicine, $1
million; health disparities, $1 million.
You indicated in your testimony that lupus is more
prevalent in African-Americans, Latinos, Native Americans and
Asians. Among African-American women, the disease afflicts
minorities three times more frequently than white women, an
estimated 1 in 250 African-American women between the ages of
15 and 65 develop the disease. Unfortunately, many people,
especially minorities, are not even aware of the disease.
I wonder what action has NIAMS taken to augment the
awareness of lupus in minority communities. I was also hoping
you could comment on the number of minority researchers who are
participating with NIH to find a cure for lupus.
Dr. Katz. Thank you very much, Mr. Jackson.
The effort in lupus has been long-term. We have developed
programs, information programs, particularly targeted to black
women. I'll be happy to send you some of that information. We
have in small booklet form, and large booklet form, for people
who are reading impaired, a booklet called, What Black Women
Should Know About Lupus Erythematosus, or What Black Women
Should Know About Lupus, I think the exact title is.
We have also tried to work with local communities through
our centers program to reach out to communities to increase the
awareness of lupus erythematosus. We've also developed
information systems for the Hispanic community now to allow
them to make a toll-free call to the NIAMS information
clearinghouse to become more aware of the problem.
It is a clear problem in terms of getting the information
out. We know from studies that we've supported that the earlier
the diagnosis can be made, the less severe the treatment has to
be. So it's an area that we are particularly concerned with. We
have a very large study called the LUMINA study, which is Lupus
in Minorities. It is run by a group in Alabama, but it
encompasses many of the programs in the south and particularly
addresses some of the concerns of the minority communities and
what we can do to intervene.
We know for example that if you even correct for
socioeconomic status, self-efficacy--the wherewithal that one
has in affecting one's disease--has a lot to do with how much
one participates, how much one knows about one's disease. All
of this is very, very important. And we're trying to address
that.
Mr. Jackson. Do you have any idea how many minority
researchers are participating in your agency or your Institute
to find a cure for lupus?
Dr. Katz. Yes. We have awarded 4.3 percent of our grants to
individuals who are minorities.
Mr. Jackson. You're not aware of any of those minorities
participating in any substandard research?
Dr. Katz. No. Not at all. Not at all.
NIAMS RELATIONSHIP WITH ORMH
Mr. Jackson. Let me ask you a question. How would you
characterize your Institute's relationship with ORMH?
Dr. Katz. My relationship with, my and the Institute's
relationship with ORMH is, I would characterize, excellent.
Since I became Director of the Institute, and I should say that
Dr. Ruffin was the co-chair of the search committee that
identified me as a candidate for this position, we have
interacted very, very closely. We have co-funded many, many
applications. We work collegially.
I think this past year, in Fiscal Year 1999, we had $2.5
million, close to $2.5 million of co-funding with the Office of
Research on Minority Health. I will tell you a recent
initiative that we've undertaken with some of the leaders at
the HBCUs has been done in collaboration with Dr. Ruffin, and
he and I are working on how best we can implement this.
HEALTH DISPARITIES
Mr. Jackson. Let me ask one final question. You indicate in
your opening testimony that there were a number of things that
you have done to address some of these fundamental health
disparities. Could you expound upon some of them and also let
us know, let the Committee know what in the future you're also
planning to do to help reach out to qualified minority
researchers?
Dr. Katz. Sure. I would say the most recent study that has
yielded very important information is the LUMINA study that I
just referred to. It's a study, again, based at the University
of Alabama that addresses not only the racial differences, but
also socioeconomic differences in terms of what brings a person
to the doctor more readily than others. The reason for that,
obviously, is to get patients in with chronic disease at a much
earlier time than they would otherwise come.
Other types of studies that we're doing are funded by our
multi-purpose arthritis and musculoskeletal diseases centers,
again to address socioeconomic differences, behavioral
differences, how one motivates people to actually participate
in the activities of the disease, of the treatment.
Mr. Jackson. Thank you for your work, Dr. Katz. Thank you,
Madam Chairman.
Dr. Katz. Thank you very much.
Mrs. Northup. Ms. Pelosi.
Ms. Pelosi. Thank you, Madam Chair.
Dr. Katz, welcome.
Dr. Katz. Thank you.
EHLERS-DANLOS SYNDROME
Ms. Pelosi. It's nice to see you again. Dr. Katz, I
appreciated the discussion about lupus. Because many of us have
constituent and personal concerns about that, so I appreciate
the Chairperson and my colleague asking about that. It allows
me to proceed to another issue that I think you're aware of my
interest in. I wanted to ask you some specific questions about
it, Ehlers-Danlos Syndrome.
I didn't see anything mentioned in your presentation on it.
But I was pleased when you said, children on the playground,
women and ethnic minorities are disproportionately affected by
many diseases that affect their daily activities. And this is
one where women would be particularly disproportionately
afflicted.
Since we spoke last year about this, there has been a
conference that was held in April by the Ehlers-Danlos National
Foundation. They have a report on clinical and biological basis
for Ehlers-Danlos Syndrome. I would hope that when you respond
to it, you can be specific about this disease, as I know you
are working very hard advancing all of the research that might
affect it.
One of the problems that comes forth is that knowledge of
the clinical manifestations and natural histories of the
different types of EDS is still evolving, whether it's the
classical type, the vascular type, the hypermobility type, etc.
It is thought that some of the research in some of this, and if
I may, I'd like to give you this report, if you don't already
have it.
Dr. Katz. I appreciate that.
Ms. Pelosi. Because it's a very useful resource. They are
trying to move on their own. But of course, none of this will
be successful unless we can have the cooperation of the
National Institute of Arthritis and Musculoskeletal and Skin
Diseases.
On the clinical side, there's a need for cross-sectional
and longitudinal studies, therapeutic trial, natural history of
all known individuals of less common types of EDS, and it goes
on and on. On the basic science side, Ehlers-Danlos Syndrome
provides an outstanding opportunity to study the biomechanical
ultrastructural and regulatory roles of collagens and
connective tissue biology.
In any event, this research will be beneficial not just for
EDS sufferers, but for other diseases as well. That's what this
summary says, which I would like to submit to you.
So I would hope that because of the people who are
suffering from this, the challenge that it presents, and
hopefully the opportunity not only for EDS but for other
diseases, that you can tell me something about the priority you
can make this at your Institute.
Dr. Katz. The priority is a very real one. I know of your
concern, I know of the concern of others as well. Although I am
sorry not to be specific, Ehlers-Danlos does fit into the group
of diseases of heritable disorders of connective tissue. And
that is one of our initiative areas for Fiscal Year 2001. We
are planning a meeting, the third international meeting on
heritable disorders of connective tissue; of course, Ehlers-
Danlos is one critical area, osteogenesis imperfecta another,
Marfan Syndrome is yet another. We bring researchers in to try
to identify those opportunities, similar to the meeting that
you talked about in April, to try to identify opportunities, so
that we at the NIH can respond, can announce to the community--
either in the form of a request for applications, which is a
specific setaside of dollars for studies in these areas, or
with a program announcement--that this is a high priority.
By virtue of our having a workshop in this area--by virtue
of our bringing in the best scientists in this area--and also
by the way, scientists who are not so familiar with this area,
to get them to interact to identify those scientific
opportunities, is what our goal is for Fiscal Year 2001. That
is a priority I have stated in my opening statement and in the
written opening statement.
We do need for a group of investigators to apply to the NIH
for grants. That is critical in this area. There are some very,
very good scientists who are working in this area. We would
like to see more activity in this area. And that's one of the
reasons for putting on a workshop.
Ms. Pelosi. That's a positive side, when I can say to my
constituents is that in this more general conference, in
which----
Dr. Katz. Well, Ehlers-Danlos is an integral part of it.
Ms. Pelosi. No, I appreciate that, I'm not challenging it,
I'm just saying that they should try to be involved with that?
Dr. Katz. I'm sure they will be involved with it. If we are
doing our job, they will be involved with it.
Ms. Pelosi. Okay, but you're doing the appropriate
outreach, so that they would be, and they're doing the
appropriate field for it?
Dr. Katz. I believe we are. Because of my concern in this
area for the last couple of years, I asked Priscilla
Ciccariello to become a member of our advisory council. She has
been an active member of the council, not only at council
meetings, but also at retreats, at planning retreats, where we
include people from the public, whether it's a scientific
planning retreat or it's a planning retreat to organize a
strategic plan.
Her organization is really a coalition organization, of
which Ehlers-Danlos is a strong part.
Ms. Pelosi. If I just may conclude, not a question, but
just say, I appreciate that. Thank you. EDNF, the Foundation,
is going to have a learning conference for those with EDNF and
physicians around the country who treat them in California in
July. So hopefully we can have some representation from the
Institute, if that's possible.
Dr. Katz. If we are invited, we will be there.
Ms. Pelosi. Wonderful. That's great. Thank you very much,
Dr. Katz.
Thank you, Mr. Chairman.
Mr. Wicker [assuming chair]. Thank you.
Mrs. Lowey.
DUCHENNE MUSCULAR DYSTROPHY
Mrs. Lowey. Thank you, Mr. Chairman.
And thank you, Dr. Katz. I talked last week with Dr.
Fischbach about families in my district whose sons are affected
by Duchenne muscular dystrophy, which strikes children. As you
well know, a child with DMD measures his life in months.
The parents are understandably frustrated, anguished about
the pace of research determining the cause and treatment for
MD. And my staff and I have been researching ways in which we
might encourage better progress. I know NIAMS will be part of a
conference later this spring on MD.
But I want to ask you to comment specifically on this
issue. Some say that adding a specific study group on muscle
would increase the opportunities for muscular dystrophy
research. Do you think that would help?
Dr. Katz. I don't think it would help, although I am not an
expert in this area. Dr. Ellie Ehrenfeld is the head of our
Center for Scientific Review. And as you know, she has recently
undertaken, with tremendous collaboration and input from the
entire scientific community, the reorganization of the study
sections.
We have a very large investment in muscle biology and
muscle diseases. So the review process obviously affects us
very, very much. We have two council members who are experts in
this area. We've discussed the issue very openly with Dr.
Ehrenfeld in terms of study section designations.
The study of muscle covers a broad spectrum, from
electrical stimulation to motors. The same people who would
review one type of application would not really be equipped at
times to review another type of application. The spectrum in
terms of our investment in muscle, goes to exercise physiology
and to clinical studies in the muscular dystrophies, whether
they're Duchenne, Beckers, fascioscapulohumeral dystrophy, or
limb-girdle dystrophy. All of those on that clinical spectrum
would not be able to be reviewed by people who are
electrophysiologists who are studying electrical stimulation of
muscle.
I don't think that one study section that would address
clinical muscle diseases would really be effective, because
there probably are not enough applications to come into that
study section. I think what we have to be diligent about, and I
know that Dr. Ellie Ehrenfeld is diligent about it, is to make
sure that we have good representation on those committees to
which the applications go. We as directors of the Institutes
work with her to make sure that that does happen, so there is
peer review which is really the basis of the way that we award
grants.
OSTEOPOROSIS
Mrs. Lowey. That's very helpful, and I hope we can work
together closely on this issue.
This morning, during the public witness hearings, I
understand that Catherine Sharp, a 31 year old woman, shared
her struggle with osteoporosis, and the particular difficulties
encountered by pre-menopausal women. I want to ask you about
the use of oral contraceptives, which Ms. Sharp referred to,
and its impact on bone density. Can you tell us anything about
the relationship, if any, between the use of the pill and
osteoporosis?
Dr. Katz. I can't tell you anything about the use of the
pill and osteoporosis in pre-menopausal women. In post-
menopausal women, it's well known that estrogen alone, in women
who have had a hysterectomy, or estrogen with progesterone in
women who have a uterus, is very effective in terms of
preventing bone loss. It's probably the best of the medications
that can be used to prevent bone loss.
We are now doing studies, as I said in my opening
statement, where we're looking for combinations of drugs that
affect osteoporosis. So two recently initiated studies, one
this year, one last year, are looking at alendronate, which is
otherwise known as Fosomax, in association with either low dose
estrogen or in association with parathyroid hormone that builds
up bone cells to see whether those combinations of therapies
will be effective.
This is a start into increasing our clinical studies in
this particular area. In terms of the major advance this year,
we know that half the usual dosage of estrogen, along with
vitamin D and calcium, can prevent bone loss. A very important
advance, because it enables women to make the choice a little
bit better in terms of the potential adverse effects.
Mrs. Lowey. You're talking about post-menopausal women.
Dr. Katz. That's in post-menopausal women. In pre-
menopausal women, we are addressing the issue of the ability of
patients with lupus to take estrogen to, theoretically, prevent
bone loss.
Mrs. Lowey. Thank you. Thank you, Mr. Chairman.
CLINICAL RESEARCH
Mr. Wicker. Thank you, Ms. Lowey.
Let me ask you, Dr. Katz, I'm sorry I had to come in late,
and I'm sorry that so many of our members are tied up with
other hearings. I think some of us have three hearings at the
same time. But let me just ask you about your clinical
research. Where is it taking place? How many locations and
who's doing the clinical research?
Dr. Katz. Specifically for clinical research, I would have
to give you an answer for the record. All of our research is
being supported at over 230 institutions around the country.
[The information follows:]
Mr. Wicker. And those institutions would be hospitals,
teaching universities?
Dr. Katz. Yes, hospitals, teaching universities, research
institutions.
Mr. Wicker. Research institutions?
Dr. Katz. Right.
Mr. Wicker. Universities?
Dr. Katz. Universities, right, academic health centers.
Research is also taking place in companies through the SBIR
grants program. So the research is taking place in many, many
areas.
Mr. Wicker. I see. And those are clinical research grants,
typically, is that correct?
Dr. Katz. Well, we have in the last couple of years started
many more clinical research programs than we were able to in
the past. That was the emphasis of my opening statement,
because the appropriation, the generous appropriation that came
from this Committee last year, enabled us to go into greater
breadth and greater depth in terms of research. And it enabled
us to initiate many clinical research studies.
Mr. Wicker. I see. And typically, how long would one of
these research institutions be involved in a specific research
program? Would it be for just one year at a time and has to be
renewed, or is it a five year program? How does that work?
Dr. Katz. It's anywhere from three to five years, and in
unusual circumstances, seven years, if we think that that is
really needed to do the study. But it's more typical for those
studies to be five years.
It depends on the type of study. For example, some of the
pilot studies that we were able to initiate this year are
taking place for three years. This is because a pilot study
really enables a group to see whether there is a feasibility to
a certain type of therapeutic intervention. And then hopefully
if it is promising, it will lead to a larger study.
PEER REVIEW PROCESS
Mr. Wicker. Where does your peer review process come in
with the awarding of these contracts and these grants?
Dr. Katz. Our peer review process comes in in two areas. In
one area, it comes in through the Center for Scientific Review.
In the other area, about 50 percent of our clinical studies or
perhaps even more, are reviewed by our study sections within
the Arthritis and Musculoskeletal and Skin Diseases Institute.
The reason for that is because those particular study sections
that we form will have the required depth and breadth in the
particular area that we are interested in.
So for example, if a project is in an area of autoimmunity,
whether it's lupus or whether it's Wegener's granulomatosis, we
can gather people within our study sections to provide that
peer review. And we have a review branch that organizes that
type of review. More of our clinical studies are reviewed by
our NIAMS study sections than by the Center for Scientific
Review.
Mr. Wicker. Okay. Well, thank you very much. I'm sure
you've been advised, as most witnesses have, that I have an
interest in how the research dollars are awarded and how
they're distributed and what sort of research you might get in
some of the smaller States that traditionally haven't had an
opportunity to participate in good research. I know Mr. Jackson
has already asked about minority research, too.
So I'm still, I'll say to you, Dr. Katz, and to Dr.
Kirschstein, I'm still trying to get my arms around this
process. I just think it's helpful for the Subcommittee to
understand the whole peer review process and the award process.
We just need to make sure that while we're getting the best
science possible that we're also involving as many of our
citizens as possible, and that we give everyone an opportunity
to participate to the extent that it's feasible.
Would you like to comment on that, Dr. Kirschstein?
Dr. Kirschstein. Yes, Mr. Wicker. We've talked about this
before. And I want to assure you, we are working on this.
Scientists from your State will be coming up and we will be
going back again in the spring. We will do that for all the
States that have not participated as much as others. We're
going to work very hard toward that.
Mr. Wicker. Thank you very much.
Dr. Katz. During those times when people come to the NIH,
we put them together with people who are specialists in those
areas.
Mr. Wicker. Indeed.
Dr. Katz. We try to give them really an educational program
in terms of how it's done, what's needed in order to be
successful.
Mr. Wicker. Great. Well, thank you very much.
Mr. Porter.
Mr. Porter [assuming chair]. Let me apologize to you, Dr.
Katz. I was called into a meeting with Chairman Young and the
Chairman of the Senate Subcommittee, Arlen Specter, and
couldn't be here. I apologize for that. I thank Mr. Wicker and
Mrs. Northup for chairing in my absence.
We have two votes coming up at a quarter of four or so, and
because we have an entire panel to consider with the Office of
the Director, the Office of AIDS Research, and Buildings and
Facilities, we will need to move on. I will have to reserve my
questions and ask that you answer them for the record.
TRIBUTE TO MR. PORTER
Dr. Katz. I would like to personally thank you, Mr. Porter,
for your support during my five years as Director of the
Institute, and for your support of our medical research and
improvement of the public health, your difference has been
tremendous in terms of your vision, your commitment. I think on
behalf of all my co-directors, we really are very, very
grateful to you.
Mr. Porter. You're very kind. As I said the other day at
our meeting with the advocacy group, the pleasure has been all
mine. I've learned so much, and as I said then, there isn't a
lot, sometimes, serving in Congress, to inspire us. But NIH is
something that does inspire all of us, and the work that you do
is so important. We want to be just as supportive as we
possibly can.
Dr. Katz. Thank you very much.
Mr. Porter. Thank you, sir.
We'll stand briefly in recess.

Mr. Porter. The subcommittee will come to order. We welcome
Dr. Vaitukaitis, the Director of the National Center for
Research Resources. Dr. Vaitukaitis, please proceed with your
statement.
Dr. Vaitukaitis. First, I would like to introduce the
people who are with me from NCRR, Dr. Louise Ramm is to my far
left. She is the Deputy Director. Next to her is Dr. John
Strandberg who is the Associate Director for comparative
medicine. To my immediate left is Anne Summers, who is director
of our Office of Finance, and of course you know the
individuals to my right very well.
OPENING STATEMENT
Mr. Chairman and members of the committee, I am pleased to
present the President's non-AIDS budget request for the
National Center for Research Resources, NCRR, for fiscal year
2001, a sum of $602.7 million, which reflects an increase of
$33.6 million over the fiscal year 2000 appropriation.
Including the estimated allocation for AIDS, total support
requested for NCRR is $714.2 million, an increase of $39.1
million over the fiscal year 2000 appropriation. Funds for the
NCRR efforts in AIDS research are included within the Office of
AIDS Research.
It is a pleasure once again to have the opportunity to
present the accomplishments of NCRR-supported investigators and
future directions for NCRR programs. Before the recent turn of
the millennium, doomsayers predicted the end of the world as we
know it, and in some respects they were right. Advances in
computer technology, bioengineering, imaging technologies,
neuroscience and genomics will revolutionize biomedical
research in the 21st century.
The NCRR mission is unique among the NIH institutes and
centers. While the other NIH components focus on particular
diseases, organ systems, or categories of research, NCRR alone
has a trans-NIH mandate--to develop and maintain the research
infrastructure that enables all lines of biomedical inquiry.
This effort transcends both clinical and basic research.
NCRR's nationwide networks for basic and clinical research
discern the molecular causes of disease, develop new preventive
strategies, and assess novel therapies for diseases that affect
majority as well as minority populations across this Nation. By
providing scientists access to advanced technologies and
sophisticated research facilities for collaborative clinical
and basic research, NCRR serves as a facilitator, or catalyst,
for biomedical discovery.
One of NCRR's main objectives is to utilize scarce or
expensive resources to the fullest by sharing them among many
investigators. This strategy is efficient and cost effective.
Each year more than 20,000 investigators, supported by more
than $2.5 billion in competitive grant support from the other
NIH components, use NCRR-supported research resources. To meet
the needs of biomedical investigators for access to costly
technologies, NCRR collaborates with the Department of Energy
and the National Science Foundation, NSF, to provide access for
biomedical investigators to high energy X-rays at the
synchrotron facilities operated by those two agencies.
BIOENGINEERING, COMPUTERS, AND ADVANCED INSTRUMENTATION
In addition, NCRR provides access to advanced computing for
health-related research by partnering with the NSF-supported
San Diego Supercomputer Center, one of the two national
partnerships for advanced computational infrastructure
currently supported by the NSF.
NCRR-funded resources have been critical to numerous
projects that advance biomedical science. Many NCRR-supported
discoveries have immediate benefits for patients; others help
basic research move forward toward this ultimate goal. For
example, separate groups of scientists, using NCRR-supported
beam lines for X-ray crystallography, have determined the
three-dimensional structure of ribosomes--our cells' protein
factories--in unprecedented detail. These studies may expedite
discovery of newer, more effective antibiotics.
Animal studies conducted at an NCRR-supported primate
center have shown that it is possible, by gene therapy, to
reverse the brain cell destruction that is characteristic of
Alzheimer's disease; and NCRR-supported clinical investigators
have developed methods to assess changes in particular areas of
the brain of depressed patients. The identification of these
specific brain areas is fundamental to designing improved
treatments for depression. According to the National Institute
of Mental Health, depression affects more than 19 million
American adults and cost society more than $30 billion in 1990.
The ongoing technological revolution has made it abundantly
clear that biomedical science is no longer the sole province of
physicians, biochemists and biologists. Engineers, physicists,
and computer scientists are essential partners for developing
and adapting new instruments and technologies for health-
related research. For example, improved imaging systems are
needed to investigate the pathophysiology of human disease by
studying patients, as well as small animals and nonhuman
primates, as disease models. NCRR proposes to support further
technological development of high-resolution imaging tools that
include computed tomography, magnetic resonance imaging [MRI]
and positron emission tomography.
Functional MRI imaging has provided investigators a
powerful technology for studies of the human brain and has
contributed significantly, with other complementary
technologies, to a virtual revolution in neuroscience research.
To further take advantage of these imaging and related
technologies, NCRR proposes to support the establishment of
regional MRI imaging resource centers where experts in
developing and using functional MRI can work with
neuroscientists to study brain disorders and also explore novel
therapies.
NCRR plans to functionally link those NCRR-supported
biomedical technology research resource centers equipped with
sophisticated imaging capabilities with general clinical
research centers at the same host institution in order to
accommodate patients from across this country for studies of
neurodegenerative and other brain disorders.
BIOINFORMATICS
The use of high-level computers and advanced computer
programs are essential components of today's health-related
research, but many biomedical scientists are not sufficiently
familiar with bioinformatics, a key enabling technology.
To help alleviate this urgent need, NCRR proposes to
establish bioinformatics centers that will advance research in
categoric areas of biomedical investigation. Those centers will
create homes for interdisciplinary teams that will establish
nurturing environments for exploration and research. Biomedical
investigators are generating data in profuse quantities.
For example, a single biomedical laboratory can generate up
to 100 terabytes of information a year--about the same as the
information in 1 million encyclopedias. In order to be useful,
the data must be indexed and stored, analyzed and abstracted.
To facilitate analysis of this data, NCRR proposes to establish
another program that will foster development of tools to
visualize data for analysis and to design future studies.
SYNCHROTRONS
Synchrotron resources, which produce the high energy X-rays
used to determine the 3-D structures of molecules, have an
enormous impact on structural biology and drug design. The
number of NIH users at NCRR-supported synchrotron beamlines
doubled between 1995 and 1997, and requests for access to these
facilities are increasing at an exponential rate. NCRR proposes
to alleviate the projected substantial shortfall for access to
beamlines by adding more staff so that the technical support is
available around the clock. This is a short-term fix.
New beamlines at the Advanced Photon Source at the Argonne
National Laboratory will allow investigators to address more
advanced structural biology grand challenges. In addition,
several new beamlines must be built at the Advanced Light
Source at the Lawrence Berkeley National Laboratory and
designed for high throughput studies of less complex structures
to meet the anticipated investigator need. This effort will
combine new developments in beamline design, X-ray detectors,
crystallography, robotics, and computational software.
GENETIC MEDICINE
Manifestations of gene action are explored through
phenotypic assessment of genetically altered animals. NCRR
proposes to support regionally linked resource centers for
these studies. In addition, NCRR must provide support for more
technical staff to maintain the rapidly expanding biologic
collections that include genetic stocks of zebra fish, fruit
fly and C. elegans. Additional staffing is also needed to
curate and standardize the genetic databases associated with
these expanding collections. Without continuous updating and
editing, databases quickly become useless and as a result,
unnecessary duplication of research results.
Health Disparities
NCRR proposes to help reduce health disparities in several
diseases that disproportionately affect minority populations by
competitively establishing several Comprehensive Centers on
Health Disparities, CCHD. Those centers are to be hosted by
medical schools located at universities that have an NCRR-
supported Research Center in Minority Institutions, RCMI,
facility for clinical research. The NCRR-CCHD initiative will
focus on diabetes, AIDS, and infant mortality, but initially
will place increased emphasis on cancer screening and
management of cardiovascular disease and stroke. This effort
will be in partnership with appropriate categoric NIH
institutes and with nearby general clinical research centers.
RESEARCH CAPACITY
NCRR proposes to continue support for construction or
renovation of biomedical research facilities to assure that
state-of-the-art research laboratories are available to conduct
the most sophisticated research. According to a 1998 National
Science Foundation survey, at least 65 percent of biomedical
research laboratories are inadequate to host sophisticated
research.
In addition, NCRR proposes to expand its Animal Facility
Improvement program to meet the institutions' needs nationally
to upgrade animal research facilities to perform genetic
research with rodents, nonhuman primates and other animal
models. To assist research-performing Historically Black
Colleges and Universities and other minority-serving
institutions in bringing their animal research facilities up to
AAALAC standards, NCRR proposes a special initiative to address
this problem.
CAREER DEVELOPMENT
Over the past several years, fewer young physicians have
pursued research careers. To help address that problem, NCRR
has initiated programs to increase the number of young
physicians in the clinical research pipeline. NCRR proposes to
extend that effort in fiscal year 2001 to include support for a
year-long medical student mentored clinical research training
program. The intent of this program is to serve as a catalyst
for young physicians to pursue careers in patient-oriented
research. The institutional GCRC or the RCMI-funded Clinical
Research Center will serve as a focal point for patient-
oriented research, through mentored, didactic training and
hands-on research.
NCRR also proposes to increase the number of Mentored,
Patient-Oriented Research Career Development Awards to
physicians and dentists at GCRC sites. This very successful
effort was formerly known as the Clinical Associate Physician
program, or CAP.
NCRR proposes to initiate a 1-year program for veterinary
students that will provide a mentored biomedical research
experience at research-intensive institutions and will enhance
the pipeline for research-oriented veterinarians. In addition,
NCRR proposes to increase the number of Special Emphasis
Research Career Awards to train veterinarians in health-related
research. The NCRR programs that I described are intended to
address the inadequate number of research-trained veterinarians
who participate in biomedical research.
I will be happy to respond to any questions you may have.
[The written statement of Dr. Vaitukaitis follows:]
RESEARCH FACILITIES
Mr. Porter. Thank you, Dr. Vaitukaitis. I want to kind of
bottom-line things at the beginning and ask you, in the face of
very strong increases for research grants at all of the
Institutes over the last few years and with the intention, that
that would continue so that the entire NIH enterprise would
have doubled over 5 years, are we presently keeping up with the
need?
I am not talking about within NIH; I am talking about the
extramural community as well. Are we keeping up with the
laboratories and research facilities and equipment that is
needed for this endeavor? Will we be able to stay ahead with
those things as we continue to provide more research funding?
That is the unfortunate bottom line, isn't it?
Dr. Vaitukaitis. That is the bottom line. It is a complex
problem because the funding that NIH, through NCRR, provides
for upgrading laboratory facilities is only a small part of the
total cost. In fact, on average, the Federal Government
provides approximately 6 to 8 percent of the cost of upgrading
facilities in general. So the onus falls on institutions for
the most part. The institutions appreciate getting competitive
grants for upgrading facilities from NIH because it helps them
provide a sign of credibility to the lay community to get
cofunding and support from donors for upgrading their
facilities.
One of the needs that is problematic for universities is
paying for high-end scientific equipment. The shared
instrumentation grant program has helped immeasurably, but that
only provides funds for equipment up to a half million dollars.
We do have a memorandum of understanding with the National
Science Foundation; if a piece of equipment is to be used by
NSF grantees, each agency contributes up to a half million
dollars, thereby contributing to equipment that may cost more
than a million dollars.
It is the equipment that costs more than a million dollars
that is problematic for universities and academic health
centers. Academic health centers are no longer in a position to
have a large amount of money available to help pay for high-end
equipment, because of the impact of managed care.
Universities are having the same problem. They don't have
sufficiently flexible funds, although there are some programs
that provide equipment as part of a centers program. For
instance, through our biomedical research technology program,
we do provide some funding. It is problematic because, for
instance, building a new beamline at Argonne may cost $10
million; fortunately the cost is spread over a couple of years
because of the time that it takes to build such a facility. But
the universities and their investigators are having a problem
coming up with the high-end equipment, and that is an unmet
need.
Mr. Porter. Originally it was thought--and you can correct
me if I'm wrong, and Dr. Kirschstein may wish to comment on
this as well--originally the idea of indirect costs in a grant
were to allow the academic medical center or whoever is
receiving the grant to have the resources to rebuild or build
new facilities as they were needed to conduct further research.
And yet, and you alluded to this in your answer to the larger
question, academic medical centers are under great siege
because of the HMO revolution going on, and there seems to be
great concern out there that they won't have the resources
needed to build the facilities in order to absorb the grants
and do the research that we hope will all flow from this
increased commitment to biomedical research funding.
I would like you to comment on that, and then I would like
you to comment on the fact that as I read it, the President's
budget would cut, not including the AIDS increase, about $77
million out of your present budget. And if you include AIDS,
its about $38 million. While the President's budget may lead to
lower figures on grants, how are you going to make up that kind
of money when you need it for facilities to have the research
institutions perform their research function?
Dr. Vaitukaitis. Let me address the indirect cost issue
first.
There exists no hard data to support or deny the fraction
of indirect costs that goes to upgrading facilities. No
systematic data has been collected that specifically identifies
NIH indirect costs as part of that pool because it includes
several other factors. There are two major components of
facilities costs, including those that are paid for directly
out of institutional funds.
But the bigger component of the indirect cost pool probably
is a factor of debt financing for borrowing. No data exists to
establish what part of that cost is included within the
indirect cost pool. Some of the accounting people at academic
health centers and universities whom we have asked about this
say that the indirect costs don't cover more than 10 percent of
the cost; but that is based on impression and not fact. I
strongly feel, and I know others feel this way, that a
systematic study needs to be undertaken so that we know exactly
where we stand and how to address this ever-increasing problem,
because research is becoming more complex.
Dr. Kirschstein. Mr. Chairman, in fact, we plan such a
study. Dr. Varmus asked and I have also asked a subunit of the
Advisory Committee to the Director to add several members to
that group, persons who are knowledgeable about construction
from our academic centers--both those that have medical schools
and those that do not--and they will be meeting sometime in the
spring to come up with an entire analysis and perhaps a new
thought, some new recommendations as to what to do about this
situation.
I have asked Dr. Vaitukaitis to chair this committee, with
these people, and we hope we will have some answers.
It is not an easy problem. The indirect costs clearly were
intended for this. They have not been able to handle it very
well. We have had funds for the construction, and the shared
instrumentation funds. Facilities are getting more and more
sophisticated, and we really need to work on this.
Mr. Porter. Now the question about the President's budget.
How are you going to do this with $80 million less next year
than you got last year?
Dr. Vaitukaitis. It will be creative on our collective
part.
Mr. Porter. I might be misreading this, my staff tells me.
I am looking at the appropriation for fiscal year 2000,
$680 million, and the request for fiscal year 2001 at $602
million.
Dr. Kirschstein. That is non-AIDS. The total is $714.2
million.
Mr. Porter. I am looking at parallel lines, but that is not
the way that you compare it. So there is some increase in the
President's budget, some $34 million. I apologize and withdraw
the question.
Mr. Bonilla.
Mr. Bonilla. Thank you, Mr. Chairman.
SOUTHWEST FOUNDATION
Dr. Vaitukaitis, it is good to see you again, and I thank
you for all of your work. I understand that the NCRR is
planning to increase funding for the Regional Primate Research
Center at the Southwest Foundation for Biomedical Research in
San Antonio. We have had one on one conversations about this
obviously over the last couple of years, and I appreciate the
support that you have given it. They are doing good work and
there is a true commitment from the community to make this a
premier center. I hope if we are able to increase your budget,
you will be able to increase their funding as well.
Dr. Vaitukaitis. They would be pleased.
Mr. Bonilla. We will give it every shot we possibly can. My
question does not involve the Primate Research Center today. I
want to go directly to a question about diabetes research.
DIABETES RESEARCH
Last year Congress asked NCRR to follow the diabetes
research working group's recommendation to increase NCRR
support of diabetes research. I understand that NCRR is
accepting applications to establish centers to isolate islet
cells for transplantation in diabetes patients.
Can you expand on your goals for diabetes research at NCRR?
Dr. Vaitukaitis. We are still negotiating this, but it is
our intent to put together a request for applications for
fiscal year 2001 to establish three to four centers that would
have standardized protocols for isolating human pancreatic
islet cells for both basic research and for transplantation
into Type I diabetics.
Mr. Bonilla. But you expect this to happen?
Dr. Vaitukaitis. I am an optimist. We had a meeting
yesterday with the NIH representatives to the Diabetes Working
Group to discuss this, and this is our highest priority.
Mr. Bonilla. If you run into unforeseen barriers, let me
know because we would like to help you work through those.
Dr. Vaitukaitis. Thank you very much.
Mr. Bonilla. Thank you, Mr. Chairman.
Mr. Porter. Thank you, Mr. Bonilla.
Mr. Dickey.
Mr. Dickey. Dr. Vaitukaitis, how are you?
Dr. Vaitukaitis. Just fine.
INSTITUTIONAL DEVELOPMENT AWARDS
Mr. Dickey. Yesterday, I mentioned to Dr. Kirschstein my
concern that Arkansas was not getting its share of NIH research
grants.
Dr. Vaitukaitis. Yes, I heard that statement.
Mr. Dickey. Well, that is all that I want, favoritism. In
what ways can we increase the research capabilities in rural
Arkansas?
Dr. Vaitukaitis. The institutions in your State are
eligible for the IDeA program that we have designed
specifically to enhance the competitiveness and train young
investigators in IDeA-eligible States. The reason that the 23
IDeA-eligible States and Puerto Rico get so little NIH funding
is that they account for only 8.5 percent of all of the NIH
applications. That was based on data analyzed in 1998, and that
indicates too few investigators who are trained in biomedical
research. We designed a program intended to address that
problem, which requires that a multidisciplinary center be led
by an established investigator, who already is funded and who
can serve as a mentor for more junior faculty. This, in turn,
will enhance the quality of faculty at the universities and
enhance recruitment of students who will be trained in these
areas. We think that this has a reasonable chance to work.
The other wrinkle is something novel. We invited program
staff from the other institutes to work with NCRR and with the
applicants from the various states where it relates to the
mission of their institute. For instance, we have NCI program
staff who will work with those applicants who are putting
together cancer-related applications. All of the major NIH
institutes are participating.
We are hoping with this kind of approach and follow-up
after awards are made that we will be able to help transition
the centers to be supported, not through the IDeA program, but
by the categoric institute to which the center relates. That
would be a sign of success for us.
Just for your information, last year we awarded a General
Clinical Research Center to the University of Arkansas for
Medical Sciences.
Mr. Dickey. I knew that. That is fantastic. Last year, was
it?
Dr. Vaitukaitis. Yes.
Mr. Dickey. Tell me again what that does.
Dr. Vaitukaitis. It is a General Clinical Research Center.
It provides infrastructure for doing clinical research and the
institution at the University of Arkansas competed very well.
Mr. Porter. We are going to look into this. I am not sure
that----
Mr. Dickey. Are you saying that we don't have enough
applicants?
Dr. Vaitukaitis. The bottom line is that there are not
enough trained investigators who do health-related research. In
some cases it is because there are no medical schools in the
State, but that is not true of yours.
Mr. Dickey. That is correct.
Dr. Vaitukaitis. It should be easier to work with faculty
at the medical school to help address this problem in Arkansas.
Dr. Kirschstein. Indeed, Mr. Dickey, it seems to me that
this notice of a General Clinical Research Center could be very
important, because physicians who are in rural parts of
Arkansas, but who want to do research related to health in
those rural areas, could spend time coming to Little Rock to
work with the physicians in the General Clinical Research
Center; and we probably could work up some sort of a program in
that regard.
I would suggest that Dr. Vaitukaitis work with many of us
and, in addition, with some of the activities of the former
Agency for Health Care Policy Research, now the Agency for
Health Care Research and Quality; that could be a combined
effort, too. So we will look into that and work with you.
Dr. Vaitukaitis. Actually, we host a lot of research from
that agency.
Mr. Dickey. Dr. Vaitukaitis, you mentioned 24, and I had
26.
Dr. Vaitukaitis. It is 23 States and Puerto Rico.
Mr. Dickey. That is 24. I thought 7 percent was spread over
26 states.
Dr. Vaitukaitis. You are quoting the number that is in Mr.
Istook's bill. Currently there are 23 States and Puerto Rico
that are eligible for funding through the IDeA program.
Mr. Dickey. Thank you very much for your consideration, Mr.
Chairman.
Mr. Porter. Thank you, Mr. Dickey.
CHIMPANZEE MANAGEMENT PROGRAM
Dr. Vaitukaitis, I want to raise a question about
chimpanzees. This is a very small part of your overall
responsibility, and yet I sit here and worry about things like
a headline saying NIH neglects aged chimps. It is not a good
headline. We see some problems with the Coulston Foundation and
the way that they are maintaining about 600 chimpanzees that
are no longer used in research and tend to be something that is
over there and we don't have to worry about it, but we do. I
wonder if you can give us your take on how well the Coulston
Foundation is doing the job that they are entrusted with? What
are the costs and what are the problems and isn't there a
better way that we can do this?
Dr. Vaitukaitis. The Coulston Foundation is a private
foundation. NCRR currently supports a colony of about 110
chimpanzees at the Coulston Foundation as one of the five sites
that we have supported for several years. In addition to that,
many of the animals at the Coulston Foundation have been used
by investigators for HIV-AIDS related research, and for
hepatitis B and hepatitis C vaccine development and other
activities, as well as studies trying to develop childhood
vaccines for RSV, respiratory syncytial virus. We have been
very concerned about the animal well-being at the Coulston
Foundation, and Dr. Wendy Baldwin, the Deputy Director of
Extramural Research at NIH, has been working closely with the
USDA and with my staff to assure that the animals are being
well maintained. The animals have been systematically examined
by veterinarians that are responsible to us, and they have
advised us that the animals are well taken care of.
We have worked with the USDA on this issue. We do not own
any animals at the Coulston Foundation. One of the agreements
with the USDA is that Coulston has agreed to divest himself of
several hundred chimpanzees. We would be willing to assume
ownership of those chimpanzees if they were offered, but we
cannot make a request to the Coulston Foundation because of
technicalities legislatively.
Dr. Kirschstein. We are deeply concerned at NIH and are
giving it one of the highest priorities to try to solve this
problem. Dr. Baldwin and the staff that is seated here with Dr.
Vaitukaitis are working very hard, and we hope we will have a
reasonable solution. We know that it is important to make sure
that these chimpanzees, many of whom are young and will live to
be 50 years of age are appropriately cared for, regardless of
expense.
Mr. Porter. There is legislation that has been introduced
in Congress to provide a permanent chimpanzee sanctuary. Does
NIH support that?
Dr. Vaitukaitis. We have developed a Chimpanzee Management
Plan in keeping with the study that the National Academy of
Sciences carried out a couple of years ago. We have the
elements of that administratively in place so that we would be
able to have chimpanzees in reserve for research purposes, for
development of vaccines should they be needed.
We are between the proverbial rock and a hard place. If we
were to place the animals in a sanctuary, as outlined in that
bill, we essentially would not have access to them for
biomedical research except for some noninvasive kinds of
activities. If a virus that is unknown to us currently became
problematic and a chimpanzee was an ideal model to develop the
vaccine, we would have no real place to turn to.
Mr. Porter. What if we could work out that problem?
Dr. Vaitukaitis. We could handle that currently within the
Chimpanzee Management Program, and if we could adapt any
program that was like that, we could work within that
framework.
Mr. Porter. I think we need to sit down and work this
through and see if we can't find a better way to address this.
Dr. Kirschstein. Dr. Baldwin has met with Congressman
Greenwood several times, and we are trying to work out these
issues. It is one of our highest priorities.
Mr. Porter. Thank you very much.
Dr. Vaitukaitis. We are concerned about the animals.
Mr. Porter. I know you are. I don't want to let this thing
drift. There seem to be some problems.
Dr. Kirschstein. I agree.
CLINICAL RESEARCH TRAINING
Mr. Porter. We are aware of the decline of physician
scientists going into clinical research and the need to do
something to stop this decline. Support for the General
Clinical Research Centers is one step in this process. What is
NIH doing to enhance the centers and encourage more medical
students to pursue a career in clinical research, and what are
your plans for the future?
Dr. Vaitukaitis. In speaking with representative physician
investigators across the GCRC sites, one recommendation was to
initiate a program to support medical students at those sites
to have hands-on clinical research opportunities and to work
with established investigators. We are putting this kind of
program in place hoping to maintain the interest of medical
students in patient-oriented clinical research so they will
pursue a career.
Another component has been included in other bills that are
still pending: a loan repayment program for clinical
investigators. This has been supported at various levels at
NIH; the burden of debt is seen as one of the barriers to
attracting and maintaining well-trained, patient-oriented
physician investigators in clinical research.
Separate from that, you are well aware of the several
programs that NIH started about a year and a half ago. These
new career developments mechanisms, the K-23 and the K-24, are
programs to support physician investigators who have completed
fellowship training, for the most part, as well as to support
faculty members half-time, who can then serve as mentors for
junior investigators, including medical students to try to
enhance research opportunities.
We are also trying to provide ancillary support through the
GCRCs to facilitate research, for instance, to provide more
research nurses that go out of the physical unit to work with
investigators to facilitate their research needs, to provide
data managers and computerization of data that would help the
investigator. They are more pressed for time than ever, but by
the same token, the research tools that are available for
clinical research are unprecedented.
There is a tension with investigators being pressed for
time and junior investigators being pressed because they have a
large debt. There are a significant number interested in
careers in clinical research when they graduate from medical
school, but we are not taking advantage of that. We are hoping
that we are starting to address that issue.
Mr. Porter. I want to try to remember something from
yesterday and that was, New Jersey is the first State to--
correct me if I'm wrong--to require repayment of the cost of
clinical trials?
Dr. Kirschstein. Yes. That is correct.
Mr. Porter. Would that help with this problem where there
is a flow of funds, if other States were to adopt or the
Federal Government were to adopt a standard?
Dr. Kirschstein. It would help clinical research trials if
there really was that type of support. Then I suspect that
physicians in training, medical students, would see something
that would give them the stability to want to enter research
careers.
Mr. Porter. Because they would know the funding would be
there, which has been threatened by this revolution in health
care delivery?
Dr. Kirschstein. That is correct.
SYNCHROTRONS
Mr. Porter. Dr. Vaitukaitis, can you tell me whether a
synchrotron is very similar to a particle accelerator?
Dr. Vaitukaitis. It is a form of a particle accelerator,
except that you are accelerating a lot more electrons in a
physical facility that could be as long as a mile--in a circle,
that is.
Mr. Porter. Could Fermi Lab's particle accelerator be used
for this same purpose?
Dr. Vaitukaitis. I am not a physicist----
Mr. Porter. Neither am I.
Dr. Vaitukaitis [continuing]. So I would have to check. I
think it is a different kind of device. Usually they are used
for bombarding in a straight line, whereas synchrotrons have
magnets that bend the electrons and photons around the field
and then use the X-rays that they can bend off with special
adjusting devices to bombard a crystal to calculate the
structure of the protein.
Mr. Porter. How many synchrotrons do we have available now?
Dr. Vaitukaitis. The Department of Energy has synchrotrons
at the Advanced Light Source, at Lawrence Berkeley, at
Stanford's Synchrotron Radiation Resource, at Argonne National
Laboratory and at Brookhaven. And then the National Science
Foundation supports one at Ithaca, New York.
Mr. Porter. Does NIH pay for users to use each of those
facilities?
Dr. Vaitukaitis. We don't pay for users, per se. We pay for
building the beamlines, and we provide staffing for the
beamlines because research is becoming very complex for
investigators. They have to use a lot of different kinds of
technologies, and they don't have time to learn
crystallography, although they have to understand the
principles. So they are requiring more support time at the
beamline sites that we support. We are also providing access
around the clock to increase the throughput at each beamline.
Mr. Porter. And the use of these facilities has increased
greatly in recent times.
Dr. Vaitukaitis. Yes. With the several genomes being
sequenced, there are many with unknown function and very small
crystals for study of macromolecules expressed by these genes.
They are using synchrotron radiation, because one can use very
small quantities of crystallized material to get the three-
dimensional structure for many if not most proteins.
Mr. Porter. So we can expect that the use of these devices
will increase even more?
Dr. Vaitukaitis. Substantially, absolutely.
Mr. Porter. And will we have enough time to meet the need?
Dr. Vaitukaitis. Our current professional judgment is that
we won't.
Mr. Porter. Did you say $10 million?
Dr. Vaitukaitis. $8 to $10 million for a single beamline,
but that is at Argonne. At the Advanced Light Source it costs
about a quarter of that for building--one could argue why not
build them all at ALS? The capabilities at Argonne are
considerably greater for dealing with more complex substances,
and we don't have that capacity at ALS. By addressing the needs
at both resources, one can do it more cost effectively.
Mr. Porter. I went out and saw the facility at Argonne and
they didn't call it a synchrotron when I was there.
Dr. Vaitukaitis. Advanced Photon Source.
Mr. Porter. That is what they called it.
Dr. Kirschstein. The National Center for Research Resources
and the National Institute of General Medical Sciences are both
deeply concerned about this and have been keeping up with a
study of what would be needed and are trying to help in this
regard. You will recall that Dr. Varmus used his 1 percent
transfer money to provide funds for upgrading the synchrotron
facilities to third generation light sources.
SCIENCE EDUCATION
Mr. Porter. What role does NCRR have in encouraging science
education? Do you do a lot in that area?
Dr. Vaitukaitis. With this committee's help and your help,
we now have an expanded program, which I think is going to be
dynamite. The report language encouraged us to include science
museums and technology centers within the cohort of resources
that we support for science education.
With that in mind, I attended the meeting of the
Association of Science Museums and Technology Centers last year
in Florida and met with the leadership of the science centers
and technology centers. I was so impressed with how creative
and imaginative these individuals are. I think it is going to
be a very creative approach collectively to addressing the main
issue, which is enhancing the public's knowledge of what NIH is
doing in its research and how that research impacts on our
educational lives and our choice of lifestyles. It will also be
designed to pique the interest of youngsters in science so they
can make appropriate lifestyle changes, but also select
appropriate courses in school and perhaps choose science as a
major in college, and then go on to graduate school.
The main focus is for public education. We held a technical
assistance workshop for these individuals about 6 weeks ago on
the morning after a snowstorm shut down the airports in
Washington. These people drove from New York, Philadelphia, and
they arrived at the meeting and the local people stayed home.
We had over a hundred attendees at this meeting, and Dr.
McNairy and his staff put together a summary of the meeting up
on our Web site, so those who could not make the meeting
because of the problems with weather have access to the
information and the advice that was provided at the meeting. We
are very enthusiastic about this and we think that this may
have a major impact in helping inform the public.
Mr. Porter. Anecdotally, if you look across the research
spectrum, don't you find a lot of the scientists to be foreign-
born, and perhaps foreign trained? Haven't we made up a lot of
our deficiency in science interest or education in our country
with people coming in from other societies to enrich ours and
provide this additional intellectual power?
Dr. Vaitukaitis. I think that is a fair observation.
Mr. Porter. It seems to me as a matter of policy, we should
not assume that this is going to happen forever. We hope it is,
but we better be doing something to get our young people into
science and interested in science at a young age and looking
forward to careers in science, or we are going to find
ourselves in a bind at some point. I think we have been very
fortunate. That is one of the great attractions of freedom,
scientists believe in truth, and obviously have to have freedom
in order to do their work and the United States has gotten the
benefit of that. I wonder why we can't do more with our own
young people.
Are you seeing a change in interest among young people that
you didn't see five or 10 years ago, or are we still seeing
that everyone wants to be a stockbroker?
Dr. Vaitukaitis. We have not been exposed to a large enough
cohort.
Dr. Kirschstein. I think there is still concern. I would
like to see this change. Many of us go out and talk at schools
and bring young people to NIH for the summer, but I don't think
that we are doing enough.
Mr. Porter. I wonder when you sit here on the Committee and
just listen to the Directors of the Institutes, you get a
feeling, I think, if you are not science trained, of the
overwhelming complexities that are there today, and I wonder if
a lot of young people say, oh, my goodness, this is too
difficult for me to think about undertaking when really if you
get the training and break it down, they could easily be a part
of it.
Dr. Kirschstein. You are absolutely right, but part of the
issue is how they are taught. If you make any field, reading,
mathematics, geography and science interesting, and if the
teachers are absorbed in the subject, the young people will get
stimulated. But that does not always happen. We have a program
in the intramural part of NIH where we bring local teachers to
the campus for the summer, so they can get hands-on experience
with our intramural scientists that undoubtedly makes them
better teachers when they go back to teach science.
Mr. Porter. I think we ought to put a lot more resources
into this area. I think the initiative is a good start, but we
have to do more.
Dr. Kirschstein. This has been a sort of pull-and-push area
for NIH. The major mission of both the Department of
Agriculture and the National Science Foundation is science
education. So we have, to some extent, used those
organizations. The Office of Research on Minority Health has a
memorandum of understanding with the National Science
Foundation about providing money to that organization for
science education for young, particularly minority, students.
So we have tended to do pilot programs like those Dr.
Vaitukaitis has described, and some others, but also to try to
help the major agencies that have the responsibility.
Mr. Porter. What we need to do is bring some of our great
marketers in here to reach kids with the right messages and the
right inspiration to get them locked into that as a possibility
for their career path.
Dr. Kirschstein. Exactly.
Mr. Porter. Dr. Vaitukaitis, you are doing a wonderful job.
I very much appreciate your testimony this morning. We want to
provide you the resources you need to meet all of the
challenges out there, and there are many, and we are going to
do the best to provide those resources. Thank you for appearing
today.
Dr. Vaitukaitis. Thank you, and I would like to thank you
on behalf of my staff and the grantees in the community for all
of your enthusiasm for biomedical research in general.
Mr. Porter. Thank you for saying that. It is easy to be
enthusiastic when I hear all of the wonderful things that are
happening.
The subcommittee will be in recess until 2:00 p.m.

DENNIS P. WILLIAMS, DEPUTY ASSISTANT SECRETARY, BUDGET, DHHS
Mr. Porter. The subcommittee will come to order. We
continue our hearings on the budget for the National Institutes
of Health, with the National Institute of Allergy and
Infectious Diseases. We are pleased to welcome Dr. Anthony S.
Fauci, the Director. Wonderful to see you, as always. I know
you have got an interesting presentation for us, and let me say
that we appreciate the outstanding work that you do at NIAID.
We think you do an absolutely marvelous job.
Dr. Fauci. Thank you.
Mr. Porter. Good to see you again.
Dr. Fauci. Thank you.
Mr. Porter. Why don't you proceed with your statement.
Dr. Fauci. Thank you very much, Mr. Chairman. Before I do
proceed, let me introduce my colleagues at the table. On my far
left is Dr. Milton Hernandez, who is the Director of the Office
of Special Populations and Research Training; Dr. John La
Montagne, who is the Deputy Director of the Institute; and Mr.
Thomas Williams, who is the Director of the Office of Financial
Management; and you know Dr. Ruth Kirschstein and Mr. Dennis
Williams.
Before I get started and give my formal oral presentation,
Mr. Chairman, I just want to take the opportunity, as many of
my colleagues have, to tell you how much I have appreciated and
continue to appreciate all of the extraordinary things that you
have done for the biomedical research community and for the
health of our Nation. You have earned our universal respect and
affection, and we will miss you very much. Thank you for
everything.
GLOBAL HEALTH
My written statement is submitted for the record. I would
like to just spend a few moments reviewing for you some of the
past accomplishments and future directions of NIAID.
[The information follows:]
Dr. Fauci. You recall from last year that I emphasized, as
I did the year before, the question of global health and how
that fits in not only with NIAID, but with the NIH in general.
But we are particularly attuned to the concept of global health
from a number of standpoints. There are many reasons to be
intimately involved in the global health endeavor. The
humanitarian objectives, in and of themselves, are enough
reason. But also there is relevance to domestic health
problems, as well as globalization of health problems, not the
least important of which we discussed at this committee many
times, including malaria, tuberculosis, and AIDS, particularly
its impact in the United States, as well as what we are paying
more attention to. For example, the economic development and
political stability of nations that we deal with in a very
close manner who are impacted in a very negative way by
problems in their nation, such as sub-Saharan Africa.
[The information follows:]
INFECTIOUS DISEASES
Dr. Fauci. Given that this is the NIAID, we are interested,
obviously, infectious diseases to point out that infectious
disease is the leading cause of death worldwide in young people
less than 45 years old. And if I showed you a chart of less
than 5 years old, it would be even a greater disproportion of
deaths due to infectious diseases. These are due to standard
diseases that we see all of the time, as well as to the
emerging and re-emerging infections, one of which we have been
discussing with this committee now for the last 18 years, and
that is HIV/AIDS.
[The information follows:]
AIDS
Dr. Fauci. This little inset is the chart I showed you last
year, you might recall, where the deaths due to AIDS were
rising until 1995. And then with the advent of the combination
therapies that have placed a major impact positively on HIV-
infected individuals, there was a dramatic decrease in deaths
due to HIV.
I also mentioned at that time that there are problems that
we were starting to see with the currently available anti-HIV
drugs. Now, one further year into that, we are starting to see
that, despite these extraordinary positive effects, there are
limitations in the current anti-HIV drugs: quality of life
issues; toxicities; persistence of viral reservoirs and
persistence of the replication of the virus; appreciating now,
to our dismay, that we will probably not be able to eradicate
the virus from these individuals, we have to think of creative
ways to control the virus, and I hope we get a chance to
discuss that during the question period; the emergence of
resistance; and cost access.
[The information follows:]
NEVIRAPINE
Dr. Fauci. There was one thing that happened this year, and
I will not use the word ``breakthrough,'' Ms. Pelosi, but
something really very important happened this year that I want
to point out to you that I am sure you have heard of, and that
is a collaborative study that was done with NIAID, the Fogarty
International Center, and our Ugandan colleagues, which studied
the transmission of HIV from infected mother to a baby,
comparing a regimen of a drug called Nevirapine in a single
dose to the mother at the onset of labor and a single dose to
the baby within 72 hours of birth and compared that with the
much more expensive AZT regimen. As a matter of fact, the
Nevirapine did 50 percent better than the AZT. The important
part about the study is that the total cost of the whole study
was $4, which now makes this economically feasible in countries
that just brushed off the possibility of ever treating anybody
for HIV under any circumstances. And this is something I
believe we need to pursue.
[The information follows:]
EMERGING DISEASES
Dr. Fauci. Now, one of the other things I spoke to you last
year about was emerging and re-emerging diseases. I know you
see a lot of charts, but I showed a chart that had about 20 to
35 new emerging infectious diseases that had occurred over the
past 5 to 10 years.
Just to underscore the point I was making last year, these
are just what happened since I testified before this committee
last March. You are aware of it. We have the West Nile fever
problem in New York and surrounding States; we have dengue now
in Texas and in Florida; and we have the ever-present threat of
influenza, which I hope we also will get a chance to talk to
you about in a little bit more detail later because this is
something that I think will dwarf some of the other emerging
disease threats, but because of the word ``influenza,'' the
flu, we tend to think it is not something very important when
compared to some of the more esoteric infections.
[The information follows:]
PATHOGEN GENOME SEQUENCING
Dr. Fauci. One of the approaches we are having towards
these infectious diseases is bringing infectious disease into
the age of genome. You have heard a lot about the Human Genome
Project. We have a project now that is sequencing many of the
major human pathogens. And the reason this is important, just
as when you get the human genome, you could do so many things
with it, when you get the genetic sequence of these microbes,
you can then have a much greater ability to develop
diagnostics, drugs and vaccines.
A couple of examples is the sequencing of the second
chromosome of the Plasmodium falciparum, the sequencing of the
Haemophilus influenzae b, the sequencing of syphilis
microorganisms, tuberculosis, et cetera.
[The information follows:]
IMMUNOLOGY
Dr. Fauci. Let me switch very briefly to the question of
immunology, the other major discipline that we cover. This is
the cover of the journal Cell from January of this year making
the point that I would like to underscore; namely, as we enter
the 21st Century, immunology is coming of age and beginning to
translate what I have been talking to you about over so many
years of basic research findings into something that really is
a practical benefit for human health.
[The information follows:]
IMMUNE TOLERANCE NETWORK
Dr. Fauci. And, again, just to make the connection between
last year and this year, this slide I showed you last year
explaining the mechanisms of what we call immunological
tolerance; how you can stop the body from reacting against
something that you do not want it to react against, like a
transplanted tissue, like its own tissue in autoimmunity or to
have a better insight into vaccine development. You can do that
by interfering with certain of the signals that the cells show
to each other.
This is fine in its conceptual standpoint. What we have
done since last year is implement now our clinical research on
immunological tolerance into a network. In other words, we have
40 research institutions with the largest contract that was
ever let by NIAID, $144,000,000 over 7 years involving
transplantation, autoimmunity, and most recently, asthma and
allergy, which I hope will really bring asthma and allergy into
the 21st Century as a sophisticated science.
[The information follows:]
HEALTH DISPARITIES
Dr. Fauci. One of the things that has been brought up
several times during this hearing, particularly when we were
all here for Dr. Kirschstein's hearing, is the question of
health disparities. NIAID, because of the nature of what we do
and the diseases that we study, is particularly sensitive to
that from three standpoints:
Many of the diseases that we are involved with--sexually
transmitted diseases, HIV/AIDS, tuberculosis, malaria--from a
scientific standpoint, are involved in the question of
disparity; also, our attention to training minority scientists,
which I hope we get a chance to get into; as well as the
question of enrollment of minorities into our clinical trials
process.
[The information follows:]
NIAID STRATEGIC PLAN
Dr. Fauci. And, finally, let me close by putting forth the
question that is asked of us here at the hearings, and a lot of
other places: Can we well spend the money that has been so
generously given to us over the past several years and
hopefully into the future?
We, as other institutes, have developed a strategic plan,
the cornerstones of which are listed here: Global health and
emerging infections, HIV/AIDS, vaccines and immune-mediated
diseases. And we have a process that goes from the grassroots
of the constituencies, our individual scientists, as well as
input from a number of ad hoc groups that has put into the
planning process something that I think will be a very good
road map for spending the money very well that hopefully you
will give to us.
Thank you very much. I would be happy to answer any
questions.
[The written statement of Dr. Fauci follows:]
WORLDWIDE DEATHS FROM INFECTIOUS DISEASES
Mr. Porter. As always, Dr. Fauci, that is a fascinating
presentation.
Dr. Fauci. Thank you.
Mr. Porter. Can you give us an idea of worldwide deaths or
death rates from HIV/AIDS, tuberculosis, malaria and influenza,
give us an idea of the impact. And maybe I am leaving out
something major, but----
Dr. Fauci. No, actually, if you look at the totality of the
AIDS epidemic, for example, there 50 million people infected,
33/34 million of which are still alive, which means about 16
million have already died, 2.6 million of which have died just
last year. So AIDS is accelerating with regard to deaths.
However, we often forget or at least put on the back burner
the diseases that I alluded to in my presentation regarding
global health. Tuberculosis kills up to 3 million people a
year; malaria kills 2.7 million people, most of which are
babies under 1 year of age in sub-Saharan Africa.
Influenza is an ever-present threat. It depends on the
individual year. In the United States, the baseline that you
see of epidemic threshold in the winter months is generally
about 20,000 deaths per year. When you have a bad year, like we
had in 1957 or 1968, it can go up to 35,000-45,000 or more.
When you have a catastrophic year, like 1918, it goes up to 20
million worldwide and 750,000 or more in the United States. So
these are real threats. The numbers are really astounding.
The thing that we are concerned about, why I, for the past
couple of years, have been emphasizing global health is that
although AIDS is always on our radar screen, we really need to
pay very special attention to diseases like tuberculosis and
malaria because the number of deaths from those really actually
outstrip HIV/AIDS.
INFLUENZA
Mr. Porter. If you look at all of these diseases and the
emerging diseases, what worries you most?
Dr. Fauci. Well, I sort of alluded to that on my emerging
disease slide. What I am concerned about a lot, I mean, I am
concerned about all diseases, be they esoteric or common
diseases, that have the capability of re-emerging in a form
that we cannot control, one of the examples of which is
antibiotic-resistant microbes, which is of great concern.
The thing that I think potentially can be the most
catastrophic is another influenza epidemic the likes of which
we saw in 1918 because of the nature of the spread of this
virus, respiratory borne, in an era of travel, where you can
have someone get influenza in China and then fly in 13.5 to 14
hours to the United States and all of a sudden you see it in
the United States.
The problem with influenza is that we know historically,
and we have decades of experience of this, is that there are
drifts of antigenicity or those components of the virus that
the body recognizes, and then there are shifts. We have drifts
from year to year. So that if I get infected with the flu and I
get a subclinical infection this year, next year, get my
vaccination, I get a little boost, then I probably will avoid
flu disease or if I get infected, it will be subclinical. But
when you have a complete shift of the antigenicity, and there
are what we call naive people in the population, and the
majority of the population is naive, they do not have that kind
of immune protection, and what you see is a normal season that
is just the people who are missing work for several days to a
week to a catastrophic situation. That can happen. I do not
want to do scare tactics, but that can happen.
Mr. Porter. And the vaccine would not be of any help
because there has been this shift.
Dr. Fauci. In general, we are pretty good at predicting the
drifts. But when you have an abrupt shift; for example, we
really dodged that silver bullet a few years ago with the bird
flu in Hong Kong that I spoke to this committee about, the H5
N1. Luckily, it did not mutate enough to be able to get
transmitted from person to person. It got transmitted from pig
to person. Had there been enough mutation in that, there would
have been complete naivete in the population against that
particular strain. So we would have been in serious trouble if
that had happened.
Mr. Porter. Do we adjust the vaccine year by year?
Dr. Fauci. Yes.
Mr. Porter. It is not the same vaccine that you got a year
ago.
Dr. Fauci. Yes. There is a committee, a coordinated group
of people--CDC, FDA, NIH, et cetera, World Health
Organization--that gets inklings and samples from what was
there the year before to be able to predict, given the level of
immunity in the population, as well as the antigenicity, which
is the reason why next year there is going to be a slight shift
in the flu components, the three components that we had this
year. There is going to be a slight shift in the year 2000.
IMMUNE TOLERANCE NETWORK
Mr. Porter. You mentioned a $144,000,000 contract with 40
institutions over 7 years. Did you mean contract?
Dr. Fauci. Yes.
Mr. Porter. Is this a contract?
Dr. Fauci. It is a contract, yes.
Mr. Porter. Give us some more background on this because
this is very unusual in size, at least.
Dr. Fauci. Yes. It is unusual in size, but what we have
done is that we have gotten truly the cream of the crop of
immunology and the cream of the crop of transplantation and
autoimmunity, and now we are enlisting our colleagues in the
asthma and allergy field.
And what we have done is made a long-term investment in
translational research from the fundamental basic observation
that you can interfere with the immune system's ability to
recognize an antigen without necessarily coming in with a
sledgehammer and suppressing everything. You know, one of the
real problems with both transplantation and autoimmunity is
that in order to suppress the aberrant immune response, you
have to suppress the entire immune response, which leaves
people at great risk for opportunistic complicating infections.
With tolerance, you can selectively block only the response to
the particular antigen.
So what we have done is that now that we have this
knowledge, we have set up this network of centers that are
going to entertain proposals to put these into clinical trials.
We actually just had the first meeting of the group that is
going to look at the proposals that came in, and I had the
opportunity to address them and talk to them a little bit about
some of the things that we are talking to you about here now.
NEVIRAPINE
Mr. Porter. You mentioned a new drug that is being used for
preventing the transmission of HIV/AIDS from mother to child.
Dr. Fauci. Right.
Mr. Porter. And you said that it was Nevir----
Dr. Fauci. Nevirapine.
Mr. Porter. Four dollars per dose.
Dr. Fauci. Four dollars for both doses. Four dollars for
the mother's and the baby's dose.
Mr. Porter. That sounds to me like a really very
inexpensive drug, but to many African countries that I
understand spend $1 or $2 per person on health care--all health
care--a year, it is probably still very expensive.
Dr. Fauci. Yes.
Mr. Porter. How do we propose to get the resources to get
countries to even use this drug?
Dr. Fauci. There are foundations, and I believe there are
Government organizations, also. See, what you are talking about
is there have been estimates, that if you really wanted to
treat everyone in Africa the way we treat people here in the
United States, notwithstanding the infrastructure problems you
are going to get in trying to even deliver the drugs, but just
the drugs themselves, it would cost in the tens of billions of
dollars. When you are talking about $4 per save here, you are
not talking about billions of dollars, you are talking about
millions of dollars, and I think that is doable.
There are foundations that we are working with right now
that are willing and able to go ahead and do that. What we have
got to do now is build up the trust of our African colleagues
that this is something that will ultimately be to the benefit
of their country, because there are concerns about the
development of resistant microorganisms or the inequity of
giving it just to infected mothers. Should you then have to
treat the mother? But we will do that in a very ethical way in
getting the ethicists from those countries, as well as our own
people, to sort of work together to come up with a plan.
Mr. Porter. Is there any money in the President's budget to
UNAID or any direct aid proposal that the United States would
give additional money for this purpose?
Dr. Fauci. Certainly not in our budget.
Mr. Porter. No, I know it is not in yours.
Dr. Kirschstein. Mr. Chairman, I think there was some
proposed at a speech that the Vice President made at the United
Nations.
Mr. Porter. Yes, I think it was Vice President Gore that
did make that proposal. I have not seen the numbers.
Dr. Kirschstein. I have not either.
Dr. Fauci. Right.
Mr. Porter. Thank you very much.
Ms. Pelosi?
Ms. Pelosi. Thank you very much, Mr. Chairman.
Welcome, Dr. Fauci, and to all of your colleagues, Dr.
Kirchstein, welcome to you as always. Thank you for your
excellent presentation.
A couple of things, and I know the time is short and there
is so much to ask. I was very impressed by what your study in
Uganda produced and I am always interested in communication and
collaboration, domestically and internationally. What is
important about Uganda is that the leadership of Uganda, the
President and the First Lady took responsibility, freed
themselves of the denial that many countries experience,
including our own, in the early stages of HIV/AIDS. This is an
example where we can learn from Africa, as well as transmit our
expertise to them.
So congratulations on that. And hopefully, in our foreign
operations budget, the Chairman sits on that committee as well,
as does Mr. Obey, Mr. Jackson, and Mrs. Lowey, we can make sure
that we have some funds specifically for Nevirapine.
The Vice President mentioned at the UN that he was going to
ask for an increased number for U.S. International AIDS. We
have been fighting that fight for many years. Hopefully, this
additional visibility and your success will make our job
easier. Congratulations on that.
Later this morning, I am going to join with Senator John
Kerry in introducing legislation for tax credits on the
research and sale of vaccines for AIDS, malaria and
tuberculosis. We introduced this bill last year, Senator Kerry
and I just for research and development, and then when the
President mentioned in his State of the Union that he wanted to
include a credit for the sale of the vaccine, we expanded it.
That is what we are introducing today. So, hopefully, we will
be able to assist with tax credits, in addition to
appropriations.
Again, I always ask in our other committee, ``What
collaboration do you have with our domestic agencies?'' and I
am asking you, here, what collaboration do you have with our
international agencies? You have made the point.
Dr. Fauci. Yes.
ASTHMA
Ms. Pelosi. So getting back to communication, on the
subject of asthma, we have seen in our other hearings, et
cetera, that children going to schools that are not clean,
where there are roaches and all that comes with them, it
increases the incidence of asthma attacks, if not increases
asthma. Do you have any collaboration or communication with the
Education Department? For example, the School Modernization
bill that the President is proposing to build new schools and
to upgrade the condition of many schools would have an impact,
especially on children in poor areas. It certainly is true in
the African-American community in our city.
Dr. Fauci. Yes. The study you are referring to actually was
done by an inner-city asthma study group that the NIAID and
NIEHS did.
Ms. Pelosi. It was yours.
Dr. Fauci. And we found that relationship between cockroach
antigens and asthma and pollutants and cleaning up the
environment. I am pleased to say that an important part of that
study has been outreach and education, not only of the
physicians in their treating, but also of the patients
themselves and their surroundings, including schools. So we do
have that kind of outreach and collaboration.
When we set the program up, we even had some criticism that
it was not all basic science, and we should just be worrying
about the scientific components. But we insisted that we would
have an important outreach and educational and behavioral
modification component of those inner-city asthma programs. And
they have been very, very successful.
Ms. Pelosi. Well, I appreciate that. And I think that your
study is a good argument for the President's School
Modernization bill as well. You talk about other environments
in which children spend time, but school is one very important
place, and we have a responsibility for that directly.
AIDS
Moving on to AIDS. Research on HIV and AIDS has led to
scientific advances that go well beyond the AIDS epidemic. You
have testified to that many times. Can you tell the committee
how the research being done by your Agency on HIV/AIDS is
advancing the field of immunology and helping NIH develop
treatments for other diseases?
Dr. Fauci. Yes. There are some very good examples of that.
The opportunities, the way some of the original immunologists
used to say decades ago, are an experiment of nature, really,
which is what AIDS is. It happens to be a microbe that
specifically and directly infects the immune system and a
particular type of cell of the immune system.
The insight we have had into what we call the regulation of
the immune system has really been astounding and has caused us
and allowed us to learn about things, like the tolerance that I
mentioned to you, and our tolerance networks, and suppression
of immune responses and hyperactivity that one sees in
autoimmunity.
Specifically, if I can give you some hard facts about what
has happened, in the arena of drug design, the whole concept of
targeted drug design is now spilling over into other areas, and
we are seeing targeted drug design for other diseases. And even
some drugs that were originally made for HIV/AIDS are now
having a great impact on other infections. Lamivudine, which is
one of the better drugs for AIDS, is now the state-of-the-art
treatment of hepatitis B, as is a drug that did not do very
well with HIV/AIDS, Adefovir is now used for hepatitis B. We
also have interferon alpha and ribavirin for hepatitis C. All
of these things had their beginnings when we were looking at
the earlier treatments of HIV. So there are conceptual
connections like understanding the immune system, as well as
specific drugs that actually got developed.
Ms. Pelosi. I appreciate that. Thank you, Dr. Fauci.
Ever since I have been in Congress, and certainly on this
committee, I have known how blessed we have been to have you
where you are, especially one whose district is so affected by
the AIDS/HIV epidemic. Over 15,000 people in my district have
died. But you have been relentless in your work to find the
details of how HIV works and to develop effective drugs, and I
want to congratulate and commend you for that breakthrough.
How are we doing on time? I should not have asked.
Thank you, Mr. Chairman. We will have another round, I
hope.
Mr. Porter. We are operating under the 7-minute rule. Maybe
we should give you a warning.
Mrs. Lowey.
HPV AND TOPICAL MICROBICIDES
Mrs. Lowey. Thank you, Mr. Chairman. I want to join my
colleagues in admiration for you too. Things are going
extraordinarily well, and we are so proud of the work you do,
and we thank you.
I want to particularly ask you about sexually transmitted
diseases, and we did talk about HIV quite a bit. And we know
that there are 15,000 a day new HIV infections around the
world. These numbers are extraordinary. And I am particularly
interested in a lot of the information that, at least for me,
is rather new concerning HPV. Obviously, the information to
date is that some strains of HPV lead to cervical cancer. We
have discussed these issues with Jeff Koplan at CDC, Rick
Klausner at the NCI, and I want to ask you to address the issue
of microbicides or any other information you have, research
that has been conducted, specifically focused on HPV. It is
extraordinary to me that there is so much ignorance out there
regarding HPV and that there is no prevention, there is no
drug, there is no cure. And we know that it is a smaller
number, a smaller percent that leads to cervical cancer, but I
am really very focused on what we are doing about it and the
progress that is currently being made.
Dr. Fauci. There are a lot of things we could say. Let me
just take two components of it. One is the question that you
brought up about what we are actually doing scientifically. As
you probably know, when you discussed with Rick Klausner, that
the NCI and NIAID have a major collaboration in HPV. The
collaboration is from both an epidemiological, as well as from
a fundamental basic science standpoint.
Our science now in microbes is very heavily centered, and
it will be with HPV, in both the sequencing of the microbes and
the determination of important antigenic determinants in
diagnostics, therapeutics and vaccines. Clearly, the answer to
the HPV problem is going to be vaccination so that women can be
vaccinated, particularly women who are at high risk of getting
transmission from a partner. We have been very successful in
the sequencing of a number of microbes such as chlamydia
trachomatis, which is a very important sexually transmitted
disease.
The other side of the coin is what you alluded to earlier;
namely, the topical microbicides, where we have really, I
believe, are starting to make some progress. I had the
opportunity to meet just a few weeks ago in early February with
Polly Harrison, who is the Director of the Alliance for
Microbicide Development, and we discussed our game plan for the
development of microbicides, the testing of new concepts, what
we have, where we are going. And, in fact, we put in an extra
$6,500,000 into that effort for Fiscal Year 2001. So we are
accelerating our effort.
I believe not only for microbes like HPV and others, but
also for HIV, that the idea or the concept of being able to
empower women to take into their own hands their ability of
inhibiting or blocking sexually transmitted diseases that their
sexual partner may not be amenable to, because of a variety of
sociological and other reasons, is a very important priority
for us.
HPV VACCINE RESEARCH
Mrs. Lowey. Could you discuss any research that is ongoing
with a vaccine. Because as you well know, many women are not
even aware they have HPV, a smaller percent of the strains lead
to cervical cancer. I think a vaccine is really critical.
Dr. Fauci. Well, we are obviously working on it. I mean, we
do not really have a vaccine right now, but we are working on a
vaccine. We are also working on more sensitive diagnostics at
the molecular level, the same way we did with chlamydia
trachomatis, where you can actually diagnose something without
necessarily culturing the microbe by doing molecular probing
with what we call PCR, polymerase chain reaction. So there is
both a diagnostic and a vaccine component to the work.
Hopefully, in future hearings, I will be able to report more
success in that.
Mrs. Lowey. So when you are talking about diagnostics, you
are talking about once the infection is there.
Dr. Fauci. Right, finding out if it is there, and then
seeing if one can develop a specific treatment for it.
Mrs. Lowey. To neutralize it and to actually cure it.
Dr. Fauci. Exactly. Right.
Mrs. Lowey. Not continue to treat it.
Dr. Fauci. Right. Microbes that ultimately lead to cancer
generally need to be around for a significant period of time.
So if you can get someone early in the diagnosis and have an
effective treatment, you may be able to avoid the problem that
one has with the development of cancers, in the same way that
hopefully the adequate treatment of some of the hepafitic now
will decrease the incidence of hepatic cancer associated with
them.
Mrs. Lowey. I thank you very much. I am particularly
interested in this area, and I look forward to being kept up-
to-date on it, and I thank you.
Dr. Fauci. You are welcome.
ASTHMA
Mrs. Lowey. My colleague, Congresswoman Pelosi, referred to
asthma, and we are all aware of what a tremendous health
problem this is, specifically in inner cities. Can you update
the subcommittee on your research regarding asthma.
Dr. Fauci. Yes. We are particularly pleased with what I
alluded to just a little bit earlier about the inner-city
asthma study that we are doing in collaboration with the
National Institute of Environmental Health Sciences, where we
looked at up to 1,000 children and made the important
observation of the connection, the causal connection, between
environmental antigens, such as cockroach antigens, and the
triggering of asthmatic attacks. Inherent in that also is the
educational component, whereby we educate both the physicians
and the patients, or prospective patients, in how to self-
manage asthma.
One of the real tragedies, particularly in inner-city areas
among minorities, which is very likely one of the reasons, one
of the important reasons, why the deaths due to asthma are much
higher in minorities than they are in nonminorities, and that
is the environment in which they are in and the fact that they
do not get what I consider to be adequate instruction in self-
management. Asthma is a disease that you can manage yourself,
with the help of physician. But if we do not take the time to
go into the community and tell people how to self-manage, then
they have a problem. This is something we are working on, and I
think The results are going to show some considerable
improvement.
On a more fundamental science basis, just this past few
months, we have now integrated our asthma and allergy program
into the immunological tolerance network. Of the $144,000,000
contract that I told you about, there were several components:
kidney and islet cell transplantation, autoimmunity, and now we
are going in with asthma and allergy.
So I am optimistic that this is going to elevate the
science of asthma and allergy really, as I say, into the 21st
Century, to not just make it something that you hit the person
with a lot of different drugs, which are good and work, but you
can actually turn off the mechanism that triggers the asthma
attack. That is really where we are going now in the 21st
Century to turn the mechanisms off and get away from this
carpet-bombing type of approach that we have with therapy,
which, as difficult as it is, it works in many people, but it
has a significant degree of toxicity. So I am actually very
excited about what is going to be happening in asthma over the
next few years. We just initiated this program, literally
within the past 6 months.
Mrs. Lowey. Thank you, Dr. Fauci.
Thank you, Mr. Chairman.
Mr. Porter. Thank you, Mrs. Lowey.
Mr. Jackson?
HEALTH DISPARITIES
Mr. Jackson. Thank you very much, Mr. Chairman, and thank
you, Dr. Fauci, for your testimony, but also for your
outstanding work at the Institute. And I want to associate
myself with all of my colleagues who congratulated you for the
work that you have done.
Mr. Chairman, Dr. Fauci's work is so outstanding that I
understand that he has been appointed to co-chair an effort to
strategically improve NIH's response to health disparities. I
am wondering, Dr. Fauci, if you could tell the committee what
exactly this effort and work will do and what you hope to
accomplish. And I am also interested in your role in
interacting with Dr. Ruffin's office.
Dr. Fauci. I would be happy to do that, Mr. Jackson.
The panel that I co-chair with Dr. Yvonne Maddox, under the
broad leadership of Dr. Kirschstein, is a panel that is going
to take a fresh, new look at the health disparity situation at
the NIH. And what our task is, and we are really on a fast
track, we have had our first meeting, we have had our
instructions sent out to the ICD Directors, and there are a
couple of components that Dr. Kirschstein alluded to in her
testimony at the overview.
First of all, this is going to be a committee of Institute
Directors. It is not going to be a committee of people who
report to the people, who report to the people, who report to
the Institute Directors because we want the Institute Directors
there, understanding and hearing what is going on.
We have charged them, at our first meeting, to develop,
according to a framework that has some commonality to it, so it
is not disparate and everybody does their own thing, to have a
strategic plan for the individual institutes. Then we are going
to develop an overall NIH strategic plan, and that is really
the bottom-line task of what this panel is. And we want very
much for it not to be just the sum of the strategic plans of
the individual institutes, but something that is far greater
than the sum of the parts and have a philosophy, a road map, of
where we are going.
The fast track is looking to get it done by the end of the
spring, so that when we get into our next budget cycle, we can
actually translate this health disparity situation into
something that will be in our budget-building process for the
next fiscal year.
NIAID MINORITY PROGRAMS
Mr. Jackson. Let me thank you for that answer, Dr. Fauci. I
think all of my colleagues acknowledge that at the Institute
for Allergy and Infectious Diseases, there is probably no one
better in the country to do and who continues to do what you
do.
One of the reasons that I filed my bill, H.R. 2391, was so
that you could continue to do what you do well, and the
responsibility for coordinating across the entire NIH these
issues of disparities would not fall upon you, it would fall
upon someone else who would cover for this committee and tell
us and share with us what that overall strategic plan is and
how each of the institutes are indeed addressing that. So I do
want to thank you for the added burden that we have placed on
you and that the director has placed on you to try and follow
up on some of this.
In your written testimony, you say that NIAID has a
longstanding commitment to increasing the cadre of minority
investigators in biomedical research. I am wondering can you
elaborate on this statement.
Dr. Fauci. Actually, could I post it up for you?
Mr. Jackson. Sure, you can, sir.
[The information follows:]
Dr. Fauci. As I mentioned, there are three ways that we try
and do this. We have basic research, we have people accruing at
the clinical trials, and we have programs. There are a number
of programs, some of which are shared with other institutes, or
other institutes actually take the lead. You are familiar with
many of them, but let me just point out a couple. I do not
think we have time to go through all of them. The research
supplements for underrepresented minorities you know about. We
have at NIAID a ``Bridging the Career Gap'' symposium, where we
bring in minority investigators and essentially try to get them
into the mainstream of grantsmanship, about how you can get in
and compete with people who have more experience, who have been
more successful.
The Minority Scientist Enhancement Awards, the Introduction
to Biomedical Research Program, I'm particularly proud of this.
We have done this now for 21 years. Each year we bring in 50/
60/75 minority students to the NIH for an intensive 3- to 4-
day, getting to know us, and we are getting to know them, and
we use----
Mr. Jackson. Dr. Fauci, let me ask you just one question,
if I can. Are you aware of any of these programs promoting or
supporting substandard research?
Dr. Fauci. No.
Mr. Jackson. None of them.
Dr. Fauci. No.
Mr. Jackson. Has it been your experience that your minority
investigators promote substandard research?
Dr. Fauci. No.
Mr. Jackson. And that has not been acceptable standard.
Dr. Fauci. No.
Mr. Jackson. Okay. But these programs do reach out and
broaden the pool of minority researchers.
Dr. Fauci. This one, I would like you to see sometime.
These kids are extraordinary. The track record of these
youngsters, who have gotten their M.D.s, their Ph.D.s and their
M.D.Ph.Ds, who come back to the NIH and work in our labs, this
is a showcase program, this Introduction to Biomedical Research
Program, and we are happy to compete with anybody, wherever
they come from.
Mr. Jackson. Is this the kind of coordination that you
would like to see across the entire NIH, in terms of----
Dr. Fauci. A lot of it is going on, but I think that making
it even more coordinated would be better.
Mr. Jackson. Thank you, Dr. Fauci.
Thank you, Mr. Chairman.
Mr. Porter. Thank you, Mr. Jackson.
Mr. Wicker.
HIV/AIDS
Mr. Wicker. Thank you, Mr. Chairman. And, Dr. Fauci, it is
good to have you with us today. The testimony is fascinating,
and it always strikes me how interrelated the various
Institutes are at NIH and how you have to work together because
the diseases that affect us and that affect people worldwide
cross so many disciplines.
Let me start by asking about HIV/AIDS. You say, in your
written testimony, HIV infections have reached an unacceptable
plateau of 40,000 per year in the United States. How long have
we been at that plateau?
Dr. Fauci. About 8 or 9 years.
Mr. Wicker. How is the rate of HIV/AIDS infection, then, in
Africa, as compared to that?
Dr. Fauci. Let me mention, if I might, Mr. Wicker, just
backtrack on your question because that is a misleading number,
40,000. Although the 40,000 has plateaued for 8 or 9 years,
there is a shift in the demography within that, where it is now
disproportionately going towards African-Americans and
Hispanics and disproportionately going towards women. So
although it has plateaued, we really need to pay attention to
making sure that we shift the direction of our education, our
behavior modification, as well as our getting these people into
the appropriate clinical trials, which is one of the things
that I alluded to about as one of the three-pronged components
of our health disparity initiative.
But getting back to Africa, sub-Saharan Africa right now,
as we have said here for a couple of years, is really a
disaster. There are 33 million people living with HIV infection
in the world today; two-thirds of which are living in sub-
Saharan Africa. The number of new infections per day is about
16,000, about 75 to 90 percent of which are in sub-Saharan
Africa. Just last year there were over 4 million infections,
about 5 million infections with HIV. So it is on this type of a
curve in sub-Saharan Africa.
What is even as frightening as that is that we are starting
to see the same thing now a couple of years behind in India,
and Asia and South Asian countries. So developing countries
have not even begun to peak yet.
Mr. Wicker. If that trend continues in Asia and sub-Saharan
Africa, play the scenario out for us a decade from now.
Dr. Fauci. A decade from now, if there is absolutely no
leveling off and decreasing in that, we are going to have
nations that are going to fall. I believe so. And when I spoke
last year here I made the comment, and I was a little hesitant
because it is getting out of my field--I know you were talking
about foreign ops and things like that that we do not do--but
this is something that should almost be a foreign policy
initiative I think, and we have heard inklings of that now. We
have heard inklings of that from the Congress, we have heard
inklings of that from the administration.
We are going to have allies that we depend upon, not only
economically, but politically and militarily, who are going to
actually fall. When you have an army in which 45 percent of the
officer corps is infected with HIV, that is just completely
unacceptable. So the implications completely transcend a very
important component, which is the humanitarian. It goes into
the economic, the political stability. So there is really going
to be truly a disaster on several fronts.
[The information follows:]
NEVIRAPINE
Mr. Wicker. And that brings me then, and I hope someone
will put up that slide about Nevirapine in Uganda while I ask
this question. I have been curious for a while, and I hope you
will help the subcommittee understand the process for the type
of research that has gotten us to the point where we are now
with the Nevirapine drug that costs $4 for the two doses and
can potentially save 400,000 lives worldwide, I understand.
So how long have we been working on that? How many
consortiums have been involved?
Dr. Fauci. Well, let me give you an example. It is years.
The drug itself got developed as part of a drug development
program that we have been involved in, in collaboration with
our industrial counterparts, our pharmaceutical colleagues and
collaborators. So it started off as a basic science approach:
Here is a target of the virus. We know that if you block this
component of the virus, we can block transmission.
Mr. Wicker. And when was that that it got started?
Dr. Fauci. That was at least 6 or 7 years ago. Then you
wind up showing that that drug works in a combination in what
we call highly active anti-retroviral therapy, forgetting
transmission from mother-to-child, for people who are already
infected. We know that it works.
But we find out something about it, and this is the real
fun and excitement of it, that unlike other drugs, it has a
particularly long half-life; in other words, if you give it to
me today, it hangs around for a day or two or three, as opposed
to giving me a drug that you have to take three or four or five
times a day.
So then you get the idea, if you want to do an experiment
and you want to do it in a way where you just want to hit that
virus at that one point as it is getting transmitted from the
mother during labor to the baby and then give it to the baby
during that first couple of days when the baby is breast-
feeding and may still have some virus from the mother. So you
give a dose to the mother, a dose to the baby, and it is purely
done on the basis of what we call the pharmacokinetics of the
drug. We know how the drug acts. Now, that is the science of
it.
The infrastructure is something that we built up again
several years ago.
Mr. Wicker. Well, where are these experiments taking place?
Any number of places across the United States? Are they taking
place in Africa?
Dr. Fauci. This is a totally African collaboration. This
was done in Uganda, in collaboration with the NIAID, the
Fogarty International Center, and the Ugandan Ministry of
Health, and it was done in our network of vaccine prevention
therapeutic trial network.
We have, in the United States and worldwide, in sub-Saharan
Africa, in Uganda, in Mali, in Tanzania, in South Africa, these
networks where we train people, we bring investigators there,
we support their infrastructure so that when you are ready for
a trial like this or a vaccine trial, you are there.
Mr. Wicker. Let me just follow up. You say a trial and a
potential. How far along and how sure are you that this is the
way to go? Have you determined that this is going to work or is
it just----
Dr. Fauci. If I had my way and I had the control of
everything, I would get some money from some foundations, and I
would go there, and with a minimal infrastructure, I would
start treating HIV-infected mothers. In fact, there is even an
argument----
Mr. Wicker. And then what is to stop you from having your
way? Does some agency have to further approve this and
clinically try it some more?
Dr. Fauci. In fairness to the other agencies, who are as
excited as I am about it, there are difficulties in getting the
host nations to buy into something like this because they get
involved in a lot of political and in-country type things that
really get in the way of what the real issue is.
Mr. Wicker. What kind of things, if I may----
Dr. Fauci. Well, for example--I hope I do not get into
trouble, but what the heck. [Laughter.]
Mr. Wicker. You will not be the first one this week.
[Laughter.]
Dr. Fauci. But I am, hopefully, going to do it for a good
reason here.
The idea that if you give a single drug to a woman and a
single dose to a baby that you might then develop resistance to
the antiviral drugs is a real consideration, if you are going
to go in and treat people, everybody in the country with the
antiviral drug. So, in other words, they are saying, ``Well, if
I give a single dose to the mother, then that mother might
develop resistance to antiviral drugs.'' So that in the
hypothesis that we are someday going to treat that mother with
an $18,000-a-year regimen, which is completely ridiculous
because we will never treat them with that, that is given as a
reason to not treat the mother to prevent infecting the baby,
which I, quite frankly, with all due respect, find to be a very
spurious argument.
Mr. Porter. Who makes that argument?
Dr. Fauci. The Ministers of Health of the developing
countries.
Mr. Porter. Why? I mean, obviously it is a spurious
argument. What is their interest here?
Dr. Fauci. It is very complicated, Mr. Chairman. It really
is. There are a lot of political things that go on between
Ministers of Health and Ministers, Prime Ministers, that I
just, I am not experienced enough to be able to decipher that
out, but it does not happen.
Mr. Hoyer. Experienced enough not to comment on it.
[Laughter.]
Mr. Porter. Thank you, Mr. Wicker.
Mr. Hoyer?
IMMUNE TOLERANCE NETWORK
Mr. Hoyer. I think your phrase about humanity's shared
vulnerability to disease is a wonderful phrase and the AIDS
epidemic, like so many others, point out how shared this
vulnerability is. We tend to think we are relatively secure in
the United States. We thought that from a defense standpoint
and we now think about it from a health standpoint, but you
pointed out that 13.5 hours from some place in Asia somebody
can be in the West Coast or for that matter the East Coast.
But let me ask you some questions about the budget. I know
that is sort of unique in this Committee. A $144,000,000 for
one contract----
Dr. Fauci. Right.
Mr. Hoyer [continuing]. Which is about what, 16 percent of
last year's budget of $881,000,000.
Dr. Fauci. Right.
Mr. Hoyer. Now, that $144,000,000, is that a----
Dr. Fauci. Seven years.
Mr. Hoyer. Seven years. So, we are talking about two--
$20,000,000 this year.
Dr. Fauci. Right. For 40 sites. So, about a half a million
a site.
Mr. Hoyer. And that is what I was going to ask. Forty
sites?
Dr. Fauci. Forty sites, right.
Mr. Hoyer. Okay. Now, how does that make it one contract?
Is it one----
Dr. Fauci. Yes.
Mr. Hoyer [continuing]. Recipient?
Dr. Fauci. What we have, when we do these clinical trial
networks, our experience, Mr. Hoyer, over the years has been
you get the very best person as sort of the head of the
executive committee for all of the sites. Because if you just
go out and say, do your own individual thing, any individual
site may not be able to get enough patients to ask and answer a
question that you need a coordinated effort among 40 sites.
So, you cannot do them individually. You have got to have
one group, one center, one person who is the primary, what we
call, principal investigator. And that person is a fellow named
Jeffrey Blustein from the University of Chicago, really one of
the best immunologists in the country and he is the head of
that executive committee, but the members of the executive
committee are representatives from all of those sites. So, when
you let a contract, you give the contract to the PI and then
the money is disbursed among the different groups, depending on
their size, depending upon their application, depending upon
their capability of conducting whatever particular type of
research you are interested in.
We do the same thing with the AIDS Clinical Trial Group. It
is a single cooperative agreement, a single grant, as it were,
but there is an executive committee that runs that.
Mr. Hoyer. How does that affect, the question I have asked
from time-to-time, the payline? That is to say is this
perceived as one grant?
Dr. Fauci. No. It does not have any impact whatever on the
payline because it is a contract.
Mr. Hoyer. Okay. So, it is not----
Dr. Fauci. It does not enter into the payline at all.
NIAID PAYLINE
Mr. Hoyer. Then let me ask you, what is the payline now at
your agency?
Dr. Fauci. Ours is----
Mr. Hoyer. What will it be based upon the 2001 budget?
Dr. Fauci. Same as last year, 20th percentile which would
give us a projected success rate of about 31, 30.5 percent
success rate, which is about the same as it was last year.
UNFUNDED SCIENCE
Mr. Hoyer. All right. Given that percentage of grantees
awards, how much good science in terms of a percentage, Doctor,
do you believe that we are unable to fund?
Dr. Fauci. You can never give an exact number but I have
thought about this a lot over the years as we have gone better
and worse and I think when you get to about 45 percent, 44, 45
percent, you are still doing very, very good science. So, if I
could fund 40 to 45 percent of the grantees that come in as
opposed to 31 percent I would be doing top-notch science, top-
notch science.
Mr. Hoyer. Am I correct in interpreting those numbers to
say then that we are leaving approximately one-half of the good
science unfunded?
Dr. Fauci. Right. If you take 15 percent of the 30, it
would be about one-half.
ASTHMA
Mr. Hoyer. Let me go to a specific question. A lot of
questions have been asked about asthma. Obviously, asthma is a
growing concern. Although I heard some sort of conflicting--I
think Dr. L'Enfant said in point of fact it is how you count
that really may have some impact on what the incidence of
asthma is.
Dr. Fauci. Right.
Mr. Hoyer. But cigarette smoking, tobacco smoking, have we
made a nexus between cigarette smoking and asthma?
Dr. Fauci. Oh, there is no question about that. I mean not
only cigarette smoking----
Mr. Hoyer. Or any other tobacco products.
Dr. Fauci [continuing]. But a lot of these nondescript
environmental pollutants. In fact, that was one of the things
that came out of our inner-city asthma study, the most
publicized of which because it was such a concrete example, was
the cockroach allergen exposure. But in addition to that, there
are a number of pollutants in the inner-city areas that make it
even more problematic for the youngsters who are getting an
ever-increasing amount of attacks from asthma. So, there is no
question environmental and cigarette smoke, either directly
your own smoking, or secondary smoke is clearly an
environmental pollutant, without question.
Mr. Hoyer. You mention in the context of one of your
answers to asthma was the management was a great problem and
those who managed it better, who had more knowledge, were very
substantially less at risk of death as a result of that.
Dr. Fauci. Correct. And hospitalization. Because our metric
was not only death, it was hospitalization and the
hospitalizations were decreased by about 30 or 40 percent.
Mr. Hoyer. In that context, all of us, many of us saw the
movie, ``As Good As It Gets'' which was about an asthmatic
child who did not get proper----
Dr. Fauci. Right.
Mr. Hoyer. And, of course, we used it, talking about
managed care reform et cetera, et cetera, but it occurs to me
as you said that, that there probably is no third party
reimbursement for education and training of how to manage that
except presumably through a doctor or health professional who
will take the time to do that, in effect, on the side.
Dr. Fauci. Yes.
Mr. Hoyer. Is that correct?
Dr. Fauci. That is correct. That is correct.
Mr. Hoyer. Have we talked to CDC and others about that
question? I mean this is the whole question of healthy
lifestyles and how you keep healthy. But it seems to me this
may be, particularly when--I am sorry Mr. Jackson has left the
room--because what your point was that there are a lot of
families who do not have the ability to manage well and the
child suffers great damage as a result of it.
Dr. Fauci. Right.
Mr. Hoyer. Have you thought about how we could perhaps get
at that?
Dr. Fauci. Yes, I have, but it is, again, one of those
things unfortunately, Mr. Hoyer, that is out of our purview.
But the only thing that I think I can do and I try to do is to
keep hammering away at that and advertising it, publishing it
in the proper journals, when we go to conferences to make that
point. To me management of a youngster with asthma with
standard drugs properly to me is as important as developing a
new wonder drug. So, if they are going to pay for the new
wonder drug, you would think maybe we should think about the
possibility of fostering the self-management.
Mr. Hoyer. Mr. Chairman, frankly, I think that was an
excellent statement and, Mr. Chairman, I think that is a very
pointed critical statement and it responds to the concerns some
have about well, we have got an existing illness, we know how
to treat it and we are spending money on finding out about new
illnesses. Obviously, we have to do both. The good news is our
country is wealthy enough to do both.
But, Mr. Chairman, we, I think, ought to address that issue
and, in particular, when you have our expert saying if you
manage this well you are going to prevent deaths,
hospitalization, incredible loss of time at schools,
absenteeism through proper management. We ought to pursue that
and I will do that with you, Mr. Chairman.
Thank you.
Dr. Fauci. Thank you.
Mr. Porter. We will have a second round at 3 minutes and
try to get in four questions. There is some research that
suggests HIV prevalence in one area versus another is not due
to behavior only. Is this good research and, if so, what are
the implications?
Dr. Fauci. I am not sure when you say--I would have to say
and, as a scientist, I flinch away from criticizing statements
or research that I have not examined, but I know a lot about
HIV and it is due to behavior. Now, the only thing that I think
you might be referring to is the transmission from mother to a
baby. I mean the baby has no behavior that the baby can avoid
to not get infected. And that is what we often hear when people
who are making a statement against the behavioristic approach,
namely, what are you talking about behavior? There are a lot of
situations. Someone who gets transfused in a country that does
not screen their blood, that is not a behavior problem. A baby
who gets infected, that is not a behavior problem.
Mr. Porter. Those are the only two instances.
Dr. Fauci. Right, exactly.
Mr. Porter. Doctor Klausner has told us about
collaborations on cancer research on a multi-nation basis where
we all ought to say the next world war ought to be the war on
disease and if we can get enemies together at the table working
on the same problem maybe that will head off future conflict.
Do you do the same kinds of things in your Institute?
Dr. Fauci. Absolutely. In fact, the international nature of
the diseases that we study are extraordinarily amenable to that
philosophy, which as I showed on my first slide, I mean that is
our early theme, global health and----
Mr. Porter. But I am talking about getting two nations that
might be at each other's throats, otherwise, working together.
Dr. Fauci. Well, we have in the Middle East the Anasheim
University collaboration between Israel and Egypt that has been
on parasitic diseases. I believe it is schistosomiasis, John,
is it?
Dr. La Montagne. Tick-borne diseases.
Mr. Porter. Yes.
Dr. Fauci. We have that. In fact, we have had that now for
I would say at least 15 years.
HUMAN CHOREATIC AND AUTOTROPHIC HORMONE
Mr. Porter. I think the more we can do in this area of
finding ways to work peacefully toward the same goals is very,
very helpful.
Researchers have found that a human hormone found in
pregnant women's urine contains a protein which destroyed the
HIV virus in preliminary experiments. Is this something that
NIAID is researching?
Dr. Fauci. Again, I am not sure what they are referring to.
In the urine that destroys----
Mr. Porter. It contains a protein which destroyed the HIV
virus in preliminary experiments. You have not heard that one?
Dr. Fauci. Well, can I poll the audience? [Laughter.]
Yes. Okay. I think I know what you are talking about. See
that? Thank you, the audience. There is a hormone called human
choreatic and autotrophic hormone, HCG, and there is a lot of
work done by a former NIH'er, Bob Gallo, who is now up at the
Institute for Human Virology at the University of Maryland, who
has demonstrated that actually not the hormone, itself, but
something that co-purifies with the hormone, is capable of
blocking HIV and also having an anti-Kaposi's sarcoma effect.
So, it is real research and it is good research.
I have seen it, if that is what you are referring to.
Mr. Porter. And this is not funded by NIAID?
Dr. Fauci. Oh, yes.
Mr. Porter. It is funded?
Dr. Fauci. Oh, yes, we fund Gallo very heavily.
Mr. Porter. And, so, you are saying that this ought to be
pursued?
Dr. Fauci. Yes, yes.
Mr. Porter. Thank you.
Mrs. Lowey.
LYME DISEASE
Mrs. Lowey. Thank you.
The question that I wanted to pursue comes from
constituents, who have been victims of Lyme disease. I just
asked my staff to give to me more information on a particular
constituent recently who came to me regarding the success of a
longer treatment for Lyme disease as compared to the usual
shorter course of antibiotic treatment.
Dr. Fauci. Right.
Mrs. Lowey. Now, she was all upset because I guess this is
controversial, the longer treatment is controversial. It worked
with her and it has not been accepted by the scientific
establishment. I would not give you the name, it probably would
not be appropriate even if I remembered it now, but perhaps you
could comment on it.
Dr. Fauci. Yes. There is a study that we are sponsoring
right now to address just this question. One of the problems
with Lyme disease is that there are two components of Lyme
disease. One is very well characterized, relatively easily
treatable, and successfully treated. That is acute Lyme
disease. If someone gets bitten by a tick you identify the
original and early manifestations which are skin
manifestations, you treat someone, the success rate is very
high.
There is another form of Lyme disease that is more
controversial but I believe, nonetheless, real. There are
probably more people who are diagnosed as chronic Lyme disease
who actually do have chronic Lyme disease which actually clouds
the picture but it is a situation that is felt to be due to the
fact that the microbes, after they initially infect you, get
into your joints, into your meninges and the brain, and cause a
variety of neurological and arthritic problems. The difficulty
in proving that is that the organism is in such a form when it
gets to that point or it is being relatively well-contained by
the immune system or maybe even the immune system is doing
damage, that it is unclear what we call the pathogenesis of
chronic Lyme disease is. Is it micro-driven or is it an
aberrant immune response to the microbe?
With that as a background, investigators have decided to do
a clinical trial to determine if you treat someone not for the
usual 10-days-to-2-weeks, the way you would do for acute Lyme
disease, but treat them for 6 months, would you get that very
last microbe out of there that would turn the disease off? And
some people have empirically tried that and it has worked, and
other people have empirically tried it and it has not worked.
Now, the problem with that statement is that there are
people in that group who do not really have chronic Lyme
disease. So, they may go on a chronic therapy for 6 months and
at the end of the 6 months feel better because they had
something else that spontaneously got better or there may be
people in there who truly do have chronic Lyme disease. So, in
order to answer that very perplexing question, we have a
clinical trial going that will hopefully do that.
Mrs. Lowey. I heard the bell go off but perhaps just a
quick one. Are the longer treatments covered by most insurance
plans or is that part of the controversy?
Dr. Fauci. I do not think so. I do not think it is an
accepted therapy so it probably would not be covered by
standard third party payers.
Mrs. Lowey. So, we will have to wait for the completion of
this trial?
Dr. Fauci. Right. Once something is established in the
literature as being an effective therapy then what usually
happens is that the companies come in and then put it on their
list of payable expenses.
Mrs. Lowey. Was that bell real so I should wait or ask the
next question.
Mr. Porter. That was real.
Mrs. Lowey. Thank you, Doctor.
Mr. Porter. Thank you, Mrs. Lowey.
Mr. Jackson?
MICROBICIDE RESEARCH
Mr. Jackson. Thank you, Mr. Chairman.
Doctor Fauci, I have three questions and I am going to read
them all so that in light of the time constraint maybe you can
answer them at your leisure.
Dr. Fauci, from a variety of statements that you have made,
I know you strongly support microbicide research and
development and I appreciate the work that NIAID is doing in
this area. Microbicides will be an important complement to the
HIV vaccines currently under development since they are likely
to be available sooner. I am wondering also because it is clear
that they will also be easier and cheaper to distribute and it
will be effective against a range of sexually transmitted
diseases in addition to HIV.
A central problem for microbicide development is a lack of
adequate Federal investment. And I understand that you have
personally recently committed to increasing NIAID investment in
this area. I am wondering what NIAID spent on microbicides in
fiscal year 2000 and what you plan to spend in fiscal year
2001? And given that your fiscal year 2001 figure is based on
the President's budget, if this Committee is able to increase
NIH's budget above what the President has recommended can we
expect to see additional resources devoted to microbicides R&D
during fiscal year 2001?
And I have also heard the concern that an additional
problem is that NIAID does not have staff scientists who are
solely dedicated to microbicide R&D. I understand that you have
two individuals who work on this issue in addition to managing
other responsibilities. Can you dedicate more focused staff and
resources on this issue?
Thank you.
Dr. Fauci. Okay. I will try to give you some quick answers.
The amount that we spent in fiscal year 2000 was about
$20,000,000. The amount we are spending with the President's
budget is about $22,000,000. And if we do get more money I have
already promised Polly Harrison, who is from the Alliance for
Microbicidal Research, that we will give an extra amount of
money probably to the tune of about of $6.5 million or more
depending upon the budget. So, we are committed to increasing
it.
A designated staff for a portfolio of that size, I think is
somewhat problematic. We will pay attention to it, Mr. Jackson,
I promise you that. If we get some activity going and the money
gets to be a greater amount and we have greater programs we
will put more people on that, I promise you.
Mr. Jackson. Thank you, Dr. Fauci.
Thank you, Mr. Chairman.
Mr. Porter. You see, even the newest member of our
Subcommittee has learned how to get around the 3-minute rule
and ask all his questions. [Laughter.]
He knows I will not cut off the answers, you see.
[Laughter.]
Well, Dr. Fauci, thank you for your testimony today. I say
often I have the greatest job in the world. I am not sure that
you do not have the greatest job in the world. But one of the
great rewards of my position has been the opportunity for all
these years to listen to you and your colleagues at NIH and to
learn and try to understand the great progress that is being
made in the war on disease. If every member of Congress could
be here this morning and listen to your testimony and
understand what is going on and the great intellect that is
brought to bear on problems afflicting humankind, I do not
think there would be any doubt about achieving greater funding
and funding all of the science that is truly good science that
is available to be funded and you have indicated that we are
funding maybe half of it in your institute.
So, I thank you for all of these years of inspiration and
understanding and learning that I have gained from listening in
the short time that we have had to do that. I just know that
the work that is being done in NIH by you and your colleagues
is always going to have the support of the American people and
of Congress, if only they can learn more about it. We talked
with Ruth about this yesterday how we can get that information
out to more members of Congress. You are just doing an awesome
job.
Dr. Fauci. Thank you.
Mr. Porter. Thank you so much.
Dr. Fauci. Thank you very much, Mr. Chairman.
Mr. Porter. We stand briefly in recess.
[The following questions were submitted to be answered for

NATIONAL EYE INSTITUTE
WITNESSES
DR. CARL KUPFER, DIRECTOR,
DR. JACK A. McLAUGHLIN, DEPUTY DIRECTOR
JUDITH DUFF, EXECUTIVE OFFICER
CAROL LIPSON FIVOZINSKY, BUDGET OFFICER
DR. RUTH L. KIRSCHSTEIN, ACTING DIRECTOR, NIH
DENNIS P. WILLIAMS, DEPUTY ASSISTANT SECRETARY, BUDGET, DHHS
Mr. Porter. The subcommittee will come to order. We
continue our hearings with the appropriation for the National
Eye Institute, and we are very pleased to welcome the dean of
the Institute directors, Dr. Carl Kupfer.
Dr. Kupfer, it is always wonderful to see you, and we just
cannot tell you how much we appreciate the job that you are
doing there at the Eye Institute, and obviously, we want to be
as supportive as we possibly can.
Why do you not proceed with your statement after you
introduce the people that are with you, and then we will have
some questions.
Introduction of Witnesses
Dr. Kupfer. Fine. Thanks, Mr. Chairman.
To my far left is Ms. Judith Duff, Executive Officer, and
to my immediate left is Ms. Carol Lipson Fivozinsky, who is our
Budget Officer. To my right is Dr. Jack McLaughlin, the Deputy
Director, and of course, Dr. Kirschstein and Mr. Williams.
Opening Statement
Mr. Chairman, I would like to start with the fact that the
National Eye Institute was created in 1968, and I came to be
its first director in January of 1970. It seems to me it would
be appropriate to give you a 30-year report, but not take a
long time to do that.
I think it is worth just looking at some of the
accomplishments. In the opening statement that I have prepared,
we list 12, but I would like to call attention to three or
four. And what I really think we want to stress is what have we
done to change the practice of ophthalmology to benefit the
American public.
I think our first major contribution has been to decrease
blindness from diabetic eye disease from 50 percent, when I
came here in 1970, to less than 5 percent today.
A second contribution that we really are very proud of
deals with the inflammation of the optic nerve that occurs
primarily in young women, and very often leads to multiple
sclerosis. A recent clinical trial has shown that with
appropriate treatment, we can not only increase the speed with
which the vision recovers, but perhaps equally important,
reduce the recurrence rate, so that patients do not have this
loss of vision once again.
A third area is the work done on premature infants with,
retinopathy of prematurity. We all recognize that although this
only affects maybe 2,000 infants a year, a blind infant, will
be blind for 50, 60, 70, 80 years. So it is very, very
important to have a major impact. We first examined the effect
of freezing the retina, where the abnormal blood vessels were
growing, and now we are using the laser and can reduce, by
almost 50 percent, the rates at which these children will
eventually lose vision.
I think these are just some of the success stories, and
there are many more, that are listed in the opening statement.
I want to stress that the major results that I find most
fulfilling are those that result from our clinical research
activity.
Now, what are the challenges in the future? Well, the nice
thing about being successful is that it generates more
questions and it generates more research opportunity. So what
are we looking at now? Well, the first area really plays very
well into what Dr. Collins has just been talking about. Once we
find the gene, the work has really just begun, because we must
find out what protein that gene produces, where the protein is
in the cell, what the normal function of the protein is, and
what happens when the gene is mutated and produces either an
abnormal protein or no protein at all. This is the area that
all the institutes, including ours, are moving ahead very, very
rapidly at the present time. As the genome project begins to
fill in the gaps, our job now is to find out what is the normal
situation and what happens when there is a mutation. So
functional genomics is going to be a very major thrust of the
Eye Institute.
The second area that is very exciting is anti-angiogenesis
activities of certain drugs on certain naturally occurring
proteins. The Eye Institute is very well situated for this,
because the problems that we have with new vessel information
are in the area of diabetes and the area of macular
degeneration. We can look into the eye and see these new
vessels growing, so if we are going to develop agents that stop
this abnormal growth, we can see it very, very easily by just
looking into the eye. And just recently some very exciting
results have come from some agents which stop the new vessel
development in animal models of diabetes, and I think we are
going to see, in the next 5 or 10 or 15 years, a major thrust
in not only preventing blood vessels in diabetic eye disease
and macular degeneration, but in other areas. It is a very
important area for cancer research, because of the need for
cancer to be nourished with blood vessels. If we could turn
those blood vessels off, that will have a major impact, and of
course, it is very important in heart disease also.
A third area is to look at the reason why various racial
groups respond differently to diseases. African-Americans have
about a 5- to 6-fold increase in glaucoma and rates to
blindness are equally high. Hispanics have a very high
prevalence of complications of diabetes. Asians have a very,
very high prevalence of high myopia. Now, usually when you
think of myopia, oh, yes, you put on a pair of glasses and
everything is all right. But if you have high-myopia, this
predisposes to retinal detachment and to holes in the macula,
in which there is a significant loss of visual function and
sometimes blindness.
So these are three areas where we are moving very, very
rapidly forward.
I want to mention very briefly the National Eye Health
Education Program. Last year you were interested in the point
that we were making on having an exhibit in shopping malls, and
we had our first in Birmingham, Alabama just a couple of months
ago. It was a great success. You had raised the question
whether people who go to a shopping mall are more interested in
shopping and do not want to stop and look at educational
things. We are told by the owners of shopping malls that the
shopping mall has now become Main Street, USA, and people go
there, not only to shop, but to congregate, to attend art
shows, music festivals, all sorts of activities. And the owners
of these malls are very anxious to have health fairs and health
projects introduced. So we are looking forward to this being a
very effective way of bringing information about diabetes,
about glaucoma, and now more recently, low vision and what can
be done about it, to the American people.
We are very much involved in translational research. We
like to take things from the laboratory and apply them to the
clinic, and this is moving ahead very, very rapidly in the
areas of autoimmune disease and in inflammatory disease.
And finally, bio-engineering is an area that is suitable
very much to the visual system, because we are dealing
basically with an optical instrument, the eye, and the bio-
engineer has many, many techniques to enhance the image that we
can see. The whole area of adaptive optics is moving very, very
rapidly.
The budget request we have for fiscal 2001, the non-AIDS
budget is $462,776,000, and the budget with the AIDS is
$473,952,000. I will be happy to answer any questions.
[The written statement of Dr. Kupfer follows:]
COMPUTER CHIP FOR RETINITIS PIGMENTOSA
Mr. Porter. Has there been a development in respect to
retinitis pigmentosa that involves the implantation of a
computer chip? Can you describe that to us?
Dr. Kupfer. Yes, sir. There has been great interest in
trying to introduce visual stimuli that are translated into
electrical impulses that would stimulate the remaining cells in
the retinas of patients with retinitis pigmentosa.
Although the cells that capture the light have usually
disappeared in retinitis pigmentosa, the cells that directly
connect the eye with the brain still appear to be present and
normal. So the idea is that if you can stimulate these cells
with images, then an individual might be able to see general
shadows, general shapes, nothing that is going to enable the
individual to read, but perhaps be helpful in ambulating,
getting about.
The latest development has used a small video camera
mounted on a pair of glasses, and the video camera translates
the light that comes in to a series of electrical impulses
which then goes through a small implant that either can be
positioned on the retina, or what has been done up to now,
several fine wires from the implant actually sit on the retina
for short periods of times. And when that video camera is
exposed to a letter or an object, the individual can ``see''
certain areas of darkness and light. And I think this is really
the first step to--if you will--provide proof of principle,
that, yes, you can stimulate a retina of a patient with
retinitis pigmentosa, yes, there can be some visual result, and
yes, this is a feasible approach.
The approach up to now has always been to try to stimulate
the brain directly, what is called the visual cortex. That is
fraught with many, many complications, so I think the fact that
the area has moved into a situation where the retina is
stimulated directly is a major step forward. We have just
funded a very major program which will involve four or five
centers throughout the United States to work on this project in
the animal, and perfect it. And the interesting thing about
this is that it is not only a multi-center study at about $2
million a year, but it is going to have matching funds from a
private donor organization to enhance the effectiveness of this
project. So we are moving very rapidly. This is a good example
of bio-engineering application.
Mr. Porter. Just to clarify something, when you said
``high-myopia,'' that would be severe myopia; is that correct?
Dr. Kupfer. Yes, sir.
Mr. Porter. Very, very poor far vision.
Dr. Kupfer. That is correct.
FUNDING INCREASES
Mr. Porter. Is it possible for you to tell us what projects
you have been able to pursue by reason of having larger
increases than the Administration has suggested for the past
two years, that you would not have been able to pursue if you
had not had that money? This is sort of another way of seeing
whether the money is well spent.
Dr. Kupfer. Right. Well, I think the first thing I would
like to mention is that we have been doing program planning
since 1972, and we are in our sixth iteration. Our plan is 1999
to the year 2003, so we are basically in the second year. We
lay out, every 5 years, where the research opportunities are,
and where the needs are and try to match those two up. So that
what we now are able to fund has sort of been identified by the
vision research community itself, and looked at by a number of
organizations representing scientists, representing lay people
who are advocates of various diseases.
The area of trying to determine what genes do normally and
what happens when they are mutated is an area that we are
moving into, and could not have moved into without increased
funding, because the technology is important, very expensive,
and the computer requirements are very intensive. As Dr.
Collins pointed out, the need to marshall large numbers of
people to collaborate on these types of projects is great. We
have got to supply resources in terms of reading those chips.
As Dr. Collins said, you can run the chip in the afternoon, but
the analysis may take months. So this is a very expensive,
intensive type activity, and we are really able to move into
this area because of the resources that are being made
available.
The whole area of angiogenesis is going to take tremendous
effort and resources to develop a whole host of new drugs and
new therapies to prevent the development of these abnormal
vessels. This is a very important determinant of preventing
diabetic eye disease, not to treat it, but to prevent it, and
to prevent macular degeneration, the wet type, which is what
usually causes the blindness.
The area of bio-engineering is going to require major
expansion. I mentioned the adaptive optics. This is a new
technology introduced from astronomy, interestingly enough,
because the astronomers have trouble when there is a lot of
turbulence in the atmosphere. The light from the stars become
distorted, so the light, which consists of many, many
wavelengths, does not reach the telescope at the same time.
There is distortion. What has been developed is a telescope
mirror and lens system which actually can change its curvature
in response to the aberration in the light coming in. In other
words, you want the light to come in as a straight plane, but
if it is distorted, the mirror and the lens will distort in the
opposite direction to correct for that. This has now been
picked up by bio-engineers, who are incorporating it into
instruments to view the back of the eye.
And just to give you an idea of the technology, the photo
receptors, the little elements that capture the light, are
about 3 microns across in diameter. A red cell is about 8
microns, so you could probably fit about 3 of these in a red
cell. You know how small the red cell is. And we can now
visualize these photo receptors individually with great
clarity. So this gives you an idea of the potential of
harnessing bio-engineers to biological problems, and I think
this whole area is going to open up. Without additional funds,
we would not have been able to move in this direction.
ADDITIONAL OPPORTUNITIES
Mr. Porter. Dr. Fauci this morning was able to say--and I
am not sure this is a fair question--he was able to say that he
felt that in his area we were funding perhaps 50 percent of the
good science that was available. Are you able to quantify that
in any way, or even give us a feeling about the availability of
good science and the chance with increasing funding of doing
better?
Dr. Kupfer. We have five programs. We have a program in
corneal disease, in cataract, in glaucoma, in retina, and in
the central nervous system. The last two, retina and central
nervous system, account for about 70 percent of all our
funding. We, at every single Council meeting, with Council
members, agonize over the fact that there are insufficient
funds to fund the best science that is there.
Vision research tends to attract people outside vision
research when there are new research opportunities, and
bioengineering is a good example. It is just suited to the
study of the visual system. So we are seeing people coming in,
excellent researchers, who want to begin on problems in the
visual system and we do not have sufficient funds, despite the
fact that almost all our funds extramurally, as you well know,
go to the individual investigator-initiated research grants. We
do not fund large center grants. We do not fund large program
projects. We have a very small contract program. We put our
money into the individual researcher. And even despite that, we
are falling short of being able to fund the very best
researchers.
I think we could easily move our funding rate up to 50
percent and still fund the very, very best research that is
being done in any field.
Mr. Porter. Dr. Kupfer, members of Congress need to know
this. Obviously when you increase any institution or program as
rapidly as we have, questions are immediately raised: Is the
money being well spent? How can it possibly be well spent?
Somehow the Directors need to send a message to members that,
in fact, it is and there is even more out there that is going
unfunded that is good science and they need to know that.
I do not know how we can do that, Ruth. I am looking at Dr.
Kirschstein here as I talk to you. We really need to get the
message into their minds.
Dr. Kirschstein. We are working on some plans.
Mr. Porter. Good.
Dr. Kirschstein. One of the things we want to do is involve
the director of the Center for Scientific Review, who gets an
overall picture of the kinds of grant applications that are
received and who can elucidate quite well what she thinks is
left over by the peer review groups, and we are going to work
on that.
MYOPIA AND NIGHT LIGHTS
Mr. Porter. Left unfunded, yes.
There was an article in USA Today back in May that talked
about in an NEI-funded study that found the rate of myopia or
nearsightedness was higher among children who had slept with a
light on. Is this so and what are the implications?
Dr. Kupfer. I would like to answer that at two levels.
First of all, the research was actually stimulated by some very
interesting observations in animals, especially chickens. If
the light is kept on 24 hours a day, seven days a week, the eye
of the chicken will slowly become larger and larger and the
chicken will become myopic. That is a fact. Everyone agrees to
that.
Now what these investigators did at the University of
Pennsylvania, very cleverly, was to look at a group of children
who they had been examining, some who were myopic, some who
were not, and they asked the parents whether the child slept
with a light on in the room when they went to sleep, whether
the light stayed on for an hour or two, or whether it stayed on
all night long.
And based upon that, they concluded that there appeared to
be more children with myopia in which the parents had kept the
light on all through the night.
This is very, very interesting, but when you do an
experiment like this where the design of the experiment was not
to ask the question is light causing the development of myopia,
you can sometimes be led astray.
For instance, it may be that parents who would tend to have
more myopia amongst themselves and for whatever reason may be
from a different group would tend to keep the light on and, of
course, their children will tend to have a higher amount of
myopia, unrelated to the light being on but due to the fact
that the parents have myopia. There are many other confounding
variables.
Now, there will soon be publications by two other
investigators using the same technique with the same flaws who
will not be able to confirm this. But what we want to see is a
controlled clinical trial done where we can really get the
answer in the appropriate way, and I think we will slowly move
in this direction.
LIGHT-ACTIVATED DRUG FOR AGE-RELATED MACULAR DEGENERATION
Mr. Porter. At this time last year there was a light-
activated drug being tested that might slow down vision loss
due to age-related macular degeneration. Is it anticipated that
this drug could be available within a year? Can you tell us the
status of this? And is there currently available anything to
slow the process of vision loss, either a drug or behavioral
treatment, for patients with AMD?
Dr. Kupfer. Yes, Mr. Porter. This is a dye that is actually
injected into the blood vessels and if there are abnormal
vessels, such as there are in macular degeneration, one can
then use a laser that will activate the drug which is in these
abnormal vessels. The drug will release poisons that will cause
the wall of the vessels to trap platelets and a clot will form
and the blood supply will be turned off to that cluster of
vessels. And this works; there is absolutely no doubt about it.
The problem is that the clot eventually will reopen and
another treatment must be required in two or three months.
However, it still is very effective in about 15 to 20 percent
of patients with this wet type of macular degeneration. The
FDA, just last month, issued a letter of intent saying that
they were going to consider approving this and I think it will
be approved within the next month or two.
So this again is another approach to the treatment of
macular degeneration. It is not perfect but for those who would
be eligible for this and who are willing to undergo treatment
every three or four months, it can maintain good vision.
CATARACTS
Mr. Porter. If you look at cataract surgery, it is a major
component of the cost of Medicare Part B and presumably as we
live longer, it is likely to grow as time goes on. Is there any
new treatment on the horizon that might bring that cost down or
make it simpler than it is today?
Dr. Kupfer. Well actually, the reimbursement for Medicare
for cataract surgery has come down considerably as----
Mr. Porter. I know. I am talking about on the technical
side.
Dr. Kupfer. We have a very high priority of trying to find
out how to slow down the development of cataracts. We would
settle for slowing it down because we know if we could slow it
down just by 10 years, we would reduce the number of cataract
operations by 50 percent, so that would be a major impact.
We have a number of very good researchers, but I cannot say
at this time that we have had any major breakthrough that is
going to be helpful. Now, this may happen tomorrow or next week
or next month.
VISION CORRECTION SURGERY
Mr. Porter. We talked last time you were here about radical
keratectomy. Am I pronouncing it correctly?
Dr. Kupfer. Radial keratotomy.
Mr. Porter. Radial keratotomy. We talked about how safe it
was and you assured us it was a fairly safe procedure.
My question, and I may be seeking free medical advice here,
but my question is, if a person, an older person, has this
procedure to correct myopia, what effect does this have upon
the problem of reading and the hardening of lenses?
Dr. Kupfer. Well, Mr. Porter, there are a number of
operations now. Radial keratotomy, which I think you are
referring to, is the first operation that was developed. That
has now been----
Mr. Porter. That is not what I am referring to. I am
referring to the LASIK surgery.
Dr. Kupfer. LASIK; that is correct. And the LASIK operation
is being done; I think it is very rapidly approaching a million
operations a year. It is considered both safe and effective by
the FDA that has reviewed the data, but you put your finger on
a very important point. That is that those of us who reach the
age of 45 notice that we need reading glasses, except if you
are very nearsighted. Then all you have to do is take your
regular glasses off and you read perfectly well.
Well, if you are nearsighted and you have an operation done
like LASIK and then your eye is corrected for distance, you are
now going to have to use reading glasses.
So it is very important to realize that you cannot throw
your glasses away. You are just exchanging glasses that you
must wear for distance for glasses you must wear for reading.
Mr. Porter. So it has no effect upon that problem.
Dr. Kupfer. That is correct.
COLLABORATIONS
Mr. Porter. Interesting.
I was interested as you gave your opening statement how
much effect the health of the eye has in respect to other
health problems and you described some of them. What kind of
collaborations do you have, for example, with NINDS and the
National Institute of Mental Health on brain function and
neurology and the eye? Are there any projects that are going on
now?
Dr. Kupfer. Well, this is a very interesting question
because I have had discussions with Dr. Fishbach, the director
of NINDS. There is a tremendous amount of overlap in what our
interests are and they are complementary. They are not
duplicative.
Let me give you an example. We are very much interested in
damage to the optic nerve. We can take the cells that make up
the optic nerve--the cell body is in the retina and the ending
is in the brain--and we can grow these cells in tissue culture.
These are the only cells of the central nervous system today
that can be grown in media that is free of all other enzymes or
hormones or any growth factors. We can study what keeps these
cells alive, what is needed. For instance, they will not stay
alive unless they are stimulated electrically and there are
certain enzymes that must be present. We learned this.
Those cells are the equivalent of the cells in the spinal
cord. So what we learn about the optic nerve is directly
translatable to the spinal cord and vice versa. Some of the
most interesting experiments about regeneration have been done
in the spinal cord and those experiments are translatable to
the optic nerve.
So in that sense we are working in parallel with very good
cross-talk, if you will.
I was having a discussion with Dr. Fischbach about the fact
that one of the things we know in Parkinson's disease is that
if in an experimental animal like a monkey that is alert and
awake--and this is a technique that is used in a number of
laboratories; it was begun in our intramural laboratory by
people who were trained to do this--you can selectively and
reversibly inhibit that part of the brain that makes dopamine,
the substantia nigra. You can just inhibit it for two or three
hours, and the monkey will show certain eye movements which are
characteristic of Parkinson's disease. And, of course, as the
inhibition wears off, the normal movements will return.
Now, this seems to be a very interesting model to develop
further and see whether we can monitor eye movements in
Parkinson's because it is very, very difficult to make the
diagnosis in early Parkinson's, and this may be a very
effective way. So discussions are being held with Dr. Fishbach
along these lines.
I would say that I know we all talk about trans-NIH
activities. I think all the things that each institute does are
trans-NIH. Back in the mid-1980s we had an investigator who was
looking at the gene-causing retinoblastoma, which is a tumor of
the eye. They isolated the gene, the RB gene, which was the
first gene to be shown to prevent cancer as long as it was
present but allowed cancer to develop if it was absent. That
had a major impact on the whole area of cancer biology.
Equally, the cancer community has come across treatments
for graft rejection which we are now using to treat uveitis in
the eye. So there is a tremendous amount of trans-NIH activity
going on all the time. I think it is only going to increase
because our problems are becoming more complex.
CONGENITAL NYSTAGMUS
Mr. Porter. I am going to try to pronounce this correctly.
Congenital nystagmus is a condition where the eyes oscillate
continuously and uncontrollably, which begins at birth or early
infancy. I understand NEI is conducting a phase one clinical
trial in humans on a surgical procedure that has been shown to
decrease nystagmus and improve visual function. Are infants
included in this clinical trial and is there a difference in
brain behavior as patients with this condition mature?
Dr. Kupfer. The condition of congenital nystagmus is a
problem because with the eyes continually moving, the visual
acuity for distance is usually not very much better than 20/
200, which means you can barely see the top letter on the
chart.
We have begun a phase one/phase two study of an operation
which has been shown to be effective in a group of dogs that
are born with congenital nystagmus. It reduces the nystagmus
and from a behavioral point of view, appears to enable them to
see better.
We have begun the study, to do the operation, first in
adults to be absolutely certain that it is safe to do. As soon
as the Data and Safety Monitoring Committee is convinced of
that, and they are the people who are watching the results of
this study, we will then probably move to children over the age
of six.
Now, it is important to move to children because if we are
really going to effect the reduction of this congenital
nystagmus, the earlier we do it, the more flexible the brain
will be in being able to respond to any surgical intervention.
So eventually we will move to children, but I think at
first we will say age six and over and then gradually lower the
age if we find it to be successful.
Mr. Porter. Dr. Kupfer, thank you for your testimony.
I was thinking as Dr. Kupfer was answering the questions
and before in his opening statement, Dr. Kirschstein, that if
we videotaped these sessions and got Members into a theater
situation and showed them the testimony, they would be as
excited about the developments in biomedical research as the
Members of this subcommittee are and I think we would not have
any problem getting the increase in funding.
Dr. Kirschstein. You get the Members; we will do the
videos.
Mr. Porter. Getting the Members is a little more difficult
than doing the videos. But it is absolutely fascinating to see
all the wonderful developments over which you are presiding and
to understand the depth of the connections in human health that
involve the eye, which is rather amazing, I think.
And, as I said before, I have benefited greatly all these
years. I had not realized that you had been--I knew you were
here before I was here. I have been here 20 years now but you
were here 10 years before I was here. That is a wonderful,
wonderful----
Dr. Kirschstein. He preceded me by four.
Mr. Porter. By four.
Dr. Kupfer. Mr. Porter, I want to add my voice to thanking
you for the energy and the understanding that you have had of
what we are doing at the National Institutes of Health and your
fantastic support.
Mr. Porter. Well, Dr. Kupfer, I was going to thank you
because I have benefited more than anyone. I really stand in
awe of the work that you do at the Eye Institute, at all the
Institutes. It is just amazing, the progress that has been and
is being made. If only Members of Congress knew about it
better, again we would have no problems.
So thank you so much for the outstanding work that you do.
We stand in recess until 10 a.m. tomorrow.

Opening Remarks
Mr. Porter. The Subcommittee will come to order.
We're pleased to have Dr. Ruth Kirschstein, the Acting
Director of NIH, to head a panel that I'm going to allow her to
introduce. This is our last hearing on NIH budgeting.
I would inform members of the audience that I have also
asked Dr. Kirschstein to bring with her Dr. Francis Collins,
who will be back about 4 o'clock to address some questions that
we have about gene research that has been discussed recently in
the press. So Dr. Collins will be able to talk to us about that
as well.
Dr. Kirschstein, we're going to have votes shortly, so
we're going to try to get as far as we can along.
INTRODUCTION OF WITNESSES
Dr. Kirschstein. Thank you, Mr. Chairman.
And we're going to have a panel at this last session. I
want to introduce the members at the table. We will start with
Dr. Neal Nathanson, who is to my far left and will be
presenting the Office of AIDS Research. Then when we have time,
Dr. Yvonne Maddox, whom I personally chose as my Acting Deputy
Director, will present the Office of the Director. And I will
then present the request for buildings and facilities.
Dr. Vivian Pinn, the Director of the Office of Research on
Women's Health and Dr. John Ruffin, the Director of the Office
of Research on Minority Health, are also here because I think
there will be members of the Committee who wish to speak to
them specifically. And I have my colleagues from the Office of
the Director behind me to help us with the questions.
We'll start with Dr. Nathanson.
BUDGET REQUEST FOR THE OFFICE OF AIDS RESEARCH
Dr. Nathanson. Thank you.
Mr. Porter, members of the Committee, I am pleased to
present the President's request for the Office of AIDS Research
for fiscal year 2001. And before I begin, I also want to join
the many other directors of NIH institutes and centers in
thanking you and the whole Committee for your stalwart support,
not only of the whole of NIH, but also for the AIDS research
program.
I am going to speak from these boards, so if you don't
mind, I'll stand up and speak from there.
This year, I would like to focus on two major issues in my
presentation to the Committee. I'll try to speak loudly so you
can all hear me. One is the global situation and particularly
in the developing world, the impact of the AIDS pandemic. The
other is the AIDS epidemic in the United States and its impact
on minority communities and the health disparities, which this
reflects. I will start off by reviewing briefly some facts that
you're all generally familiar with, namely the AIDS epidemic,
which in fact drives our research programs. Then I will turn to
some of the research programs themselves.
[The information follows:]
AIDS EPIDEMIC
Dr. Nathanson. This first board shows, for sub-Saharan
Africa, which is the epicenter of the global epidemic, exactly
how severe the epidemic has become. There are now over 20
million individuals living with HIV or AIDS [Figure 1]. And of
course, there are 10 to 15 million in this area who have
already died of AIDS.
This pandemic is so severe that in one of the recent
reports from Senator Durbin, who recently returned from Africa,
he referred to one of the countries as ``a nation turned
hospice,'' which says it all. For the first time in January,
the U.N. Security Council recognized a disease, namely the AIDS
epidemic, as a security risk. So clearly, this is the biblical
plague of our times.
[The information follows:]
Dr. Nathanson. Now, turning to the United States, we have a
somewhat different situation. Compared to 4 million new
infections a year in Africa, we're talking about 40,000 in the
U.S. [Figure 2]. But there are two problems here. The first to
which Dr. Fauci made reference last week, is the fact that the
number of new infections per year, which is the most important
index of our public health success, has remained constant for
almost 10 years. This should really be considered a public
health failure. To get this disease under control, we should be
reducing the number of new infections each year.
Another reflection is that we have approximately 800,000
individuals living with HIV or AIDS in the United States, all
of whom under present circumstances will eventually die of this
disease, because at present we do not have any cures.
[The information follows:]
Dr. Nathanson. The other problem that we face in the United
States is shown on the next board [Figure 3], namely, the fact
that the AIDS epidemic in fact is not static. I'm sorry that
Mr. Jackson can't see this board, although you are aware of all
the facts. The AIDS epidemic is moving more and more into our
minority communities. Over two-thirds of those affected with
AIDS each year are from the minority communities. In addition,
of course, women are much more affected now, representing about
25 percent of the new cases of AIDS.
[The information follows:]
Dr. Nathanson. When you look at the incidence of new
infections, the discrepancies, the health disparities, are even
more extreme [Figure 4]. On the left, African-American men and
women, in the middle, Hispanic men and women, and on the right,
the white population. Certainly, this is a very dramatic
demonstration of a health disparity that has, in fact, been a
major theme in developing our research programs.
[The information follows:]
AIDS RESEARCH PROGRAMS
Dr. Nathanson. Now, I want to turn to the research programs
themselves. I would like to focus first on our therapeutics
program [Figure 5]. I will have to be quite brief here, then of
course I'll be glad to answer questions. In therapy, we are
continuing to invest a large amount of money in the development
of new targets and new drugs. This program is the one that gave
rise to the drugs we presently have.
But turning to the clinical application, we have run into
two major problems, to which Dr. Fauci also alluded. The first
is that although we have a very effective group of drugs called
highly active anti-retroviral therapy, these have failed to
cure infections and eliminate the virus. That has meant that
individuals who are under therapy must continue indefinitely.
This has led to the discovery that there are many side
effects and other problems, such as drug resistance, and
there's also a problem of adherence or compliance. It's very
difficult for people to take these drugs, a very complicated
and expensive regimen, for many, many years. That's led to a
whole paradigm shift, or an additional set of clinical trials
that focus on issues like when to start therapy, what drugs to
use.
But the third point down here which I want to emphasize is
one that impacts particularly on minority communities, namely
that the application of optimal therapy is not equal throughout
the United States. In one survey, approximately 25 percent of
people were estimated to be getting less than optimal
treatment. So we are also supporting research efforts that are
focused on trying to reduce this health disparity, including an
outreach to minorities and training of minority investigators.
[The information follows:]
Dr. Nathanson. Turning now to prevention, of course, that's
the ultimate approach to an infectious diseases, and this
summarizes a great deal of work in many, many programs [Figure
6]. The essence of prevention is starting with an infected
individual, to prevent transmission to an uninfected
individual. Our programs, and I don't have time to go into all
of them specifically, partly attack the various ways in which
we can reduce the possibility or the probability or the
likelihood that an infected individual will transmit to an
uninfected individual. Then we have a set of approaches that
are designed to protect the uninfected individual, again using
a variety of approaches.
[The information follows:]
Dr. Nathanson. Of course the ultimate prevention technique
is a vaccine. My last board focuses on vaccines [Figure 7]. Our
progress there is incremental. It is substantial but slow. This
just epitomizes one piece of the research program, namely an
animal model, where we can quickly test vaccine candidates.
What this shows is the amount of virus in the blood of a monkey
infected with a simian AIDS virus that will in fact develop a
counterpart of human AIDS. And by contrast, the effect of a
vaccine which reduces progression to AIDS and also reduces the
amount of virus, although it doesn't give absolute protection.
[The information follows:]
Dr. Nathanson. Now, I would like to summarize by returning
to the global picture and pointing out that our program really
focuses primarily in two major areas [Figure 8]. First of all,
the developing world, particularly sub-Saharan Africa, where
approximately 95 percent of all AIDS cases and infections take
place. There our focus is on prevention including perinatal
prevention that Dr. Fauci described, but moving on to
prevention of heterosexual transmission and of course,
increasingly, vaccine trials.
In the United States, where 800,000 to 900,000 people are
living with HIV and AIDS, our focus is on trying to go where
the epidemic is to deal with health disparities and also to add
to a prevention agenda a major investment in improved therapies
and new therapies. But also with considerable attention to
making sure that these are delivered where the epidemic is,
which is increasingly in our minority communities.
We thank you again for your support, and of course, I'd be
pleased to answer your questions.
[The prepared statement follows:]
BUDGET REQUEST FOR THE OFFICE OF THE DIRECTOR
Dr. Kirschstein. We're going to ask Dr. Maddox now to
present the Office of the Director's budget.
Dr. Maddox. I'm pleased to present the President's fiscal
year 2001 budget request for the Office of the Director of the
National Institutes of Health. This is the first time that I've
had an opportunity to come before this Committee to provide
testimony, and I welcome the opportunity to do so.
Mr. Porter, I too would like to join my colleagues in
thanking you for all your efforts under the auspices of this
Committee. We really appreciate all that you've done on behalf
of the American people and I thank you on behalf of the
National Institutes of Health.
As you know, the Office of the Director provides leadership
and coordination related to the research activities of the
entire agency, both the intramural and the extramural programs.
Thus, the OD is the entity that's responsible for the
management of the essential centralized services, programs and
functions. In addition, the OD is responsible for a number of
special research programs and offices established within its
purview.
The President's fiscal year 2001 budget request for the OD
is $262.5 million, an increase of $25.2 million over the fiscal
year 2000 appropriations, not including AIDS, of which Dr.
Nathanson has already addressed.
I should mention that the specific budgets for each of the
offices that come under the purview of the OD are contained
within this budget request. The specific dollar figures are
each within the entity and also these can be found in the
justification document, as well as a description of each
individual office. I've also added some specifics of the
offices in my written statement.
Thus, I would like to take the few minutes left to me to
highlight some of the accomplishments of the offices that come
under the Office of the Director of the National Institutes of
Health. I have sat and listened attentively at these hearings
and have heard members of this Committee speak about the
importance of engaging youngsters early in life in the science
arena. And particularly, we've heard that there is a role for
NIH in this. And also, that there's a role for NIH in making
the public more aware of what NIH is and what NIH does.
OFFICE OF SCIENCE EDUCATION
I'm pleased to present to you some of the activities that
come within the purview of the Office of the Director, and
specifically, some of the activities that have been coordinated
through the Office of Science Education. I'm pleased to have
Dr. Bruce Fuchs here with me today, who is helping in the
display, but, also, he is the director of that office. You have
at your place settings some of the specific brochures that have
come out of this office.
[The information referred to follows:]
Dr. Maddox. I'm using this simple poster [Figure 1] to
illuminate and to speak to you about some of the special
programs that we have put in place over the last year. In the
area of science education, we're very much interested in
developing curriculum that will assist teachers as well as
parents in educating children early on. Here, we're speaking to
a curriculum supplement series that we developed that serves
the kindergarten as well as through 12th grade programs. These
supplements were developed with the Office of Science
Education, but not in isolation. The Office of Science
Education works with the Office of Research on Women's Health,
the Office of Research on Minority Health, the ICs and
specifically works with the scientists in the community as well
as the teachers to develop these series.
The series that you have in front of you is a series that
we have developed for grades 9 through 12. But on the left
here, you'll see a new series that we are developing for
youngsters in grades first and second. This series will be
available to the teachers and the community beginning in late
fall.
We also believe in and agree with everything that this
Committee has said to us as it relates to our role in educating
the adult public. And specifically, we're talking about the lay
as well as the professional public. The Office of Science
Education has also worked with scientists and experts in the
community to develop a mini-med school. This is a program in
which we actually design curricula as well as lecture series
that we present on the NIH campus. We're now working with
universities and colleges around the country to assist them in
developing their own mini-med schools.
Another attraction that the Office of Science Education has
been very active in producing has been something that we call
our science in the cinema series. And this series has allowed
us to bring more than 15,000 participants to the NIH campus to
visualize films that have a medical or research theme. We bring
in expert scientists who actually introduce the films and are
available for discussions of the films later.
LOAN REPAYMENT PROGRAM
The reason I bring up this whole business of cultivating
medical researchers is because it's important not only to plant
the seeds of medical research, but also to support the plants.
This other mechanism that I'm bringing to your attention is our
loan repayment program. The loan repayment program is a program
that is right now, for the most part, a program that's
conducted through the intramural program at NIH.
This program allows us to provide loan repayment to
clinical researchers, undergraduate scholarships for
disadvantaged students. We also have a loan repayment program
for individuals who come to the NIH who want to work in AIDS
research, and we have a general research loan repayment program
for individuals who want to do clinical as well as basic
research.
For the fiscal year 2001 budget request, you will also see
$1.4 million requested to bring a loan repayment program to the
extramural program. This would be specifically to develop a
clinical research loan repayment program for the extramural
scientists.
Mr. Porter. Dr. Maddox, I'm sorry to interrupt you, but
we're going to have to go vote, and take a short recess. Then
we'll be right back. Time is running out.
The Subcommittee will stand in recess for the votes.
[Recess.]
Mr. Porter. Now, then, please proceed.
ACADEMIC RESEARCH ENHANCEMENT AWARD PROGRAM
Dr. Maddox. I'd like to finish this segment on cultivating
medical researchers by spending some time talking to you about
the AREA research program, or the Academic Research Enhancement
Award Program. This program is designed to support research at
institutions that are less research intensive. So here we're
talking about the smaller universities that don't have an awful
lot of NIH funding. For fiscal year 1999, the OD provided
support for 164 of these awards to various programs around the
country for an amount of about $16.5 million. We're requesting
as part of the President's budget request $17.3 million to
advance and enhance this program.
We do feel that smaller institutions and colleges need to
be involved in our research endeavor, and specifically as it
relates to cultivating researchers. Because many of the
researchers do go to the smaller institutions.
[The information follows:]
HEALTH DISPARITIES
Dr. Maddox. Each of the institute directors who has come
before you at this hearing, as well as Dr. Kirschstein, when
she began her opening remarks, spoke to you about how NIH plans
to address the issue of health disparity. I bring this chart
[Figure 2] to your attention, there are copies of it at your
places. I will say that the NIH certainly is committed to
addressing and eliminating health disparities.
But we plan to do more than just develop a strategic plan.
You've heard many of the institute directors speak about the
trans-NIH working group made up of IC directors and how this
group will be working to devise their own individual strategic
plans as well as to come up with an NIH plan that will then be
overseen by Dr. Ruffin and his office, as well as Dr.
Kirschstein. It is important to have a research agenda as part
of our plan.
We believe that NIH, being a premier research enterprise,
needs to do more than just establish a research initiative. We
need a program of action. In looking at this poster, you can
see that we are planning to put together a real effort here to
recruit and train more minorities to go into research
investigations. We also plan to do more in the community
outreach phases and to enhance public awareness of the NIH
programs that are directed toward research in minority
communities.
We're going to work hard to include more minorities in the
rank and file, as well as to include more minorities in peer
review groups as well as in conferences. And when we talk about
enhancing the public awareness, we believe that this is a time
for us to be more proactive, and we have a health fair that's
coming up in June, on the 2nd and 3rd. We will be focusing
specifically on health disparities at this fair.
We also believe that we could be doing more in building
bridges and partnerships between the various institutions, both
the Hispanic serving institutions as well as the historically
black colleges and universities and the tribal colleges, and we
will be stepping up our activities in those arenas.
Last, but not least, we believe that we need to do more in
defining health disparities and then being able to code, to
track, to analyze and to evaluate the progress and results that
we have. This would be important for us in budget
considerations, but also in informing the public about what NIH
is doing in this area.
We believe that this is an important time for the agency.
We think we've learned a lot over this last year in particular,
as it relates to issues surrounding health disparities. And we
think the time has certainly come for us to be addressing this
and aggressively approaching solutions.
Thank you, Mr. Chairman.
[The prepared statement follows:]
Mr. Porter. Thank you, Dr. Maddox.
[The following questions were submitted to be answered for

BUDGET REQUEST FOR BUILDINGS AND FACILITIES
Dr. Kirschstein. Mr. Porter, I'm now going to speak to the
Buildings and Facilities Request. Our scientists have to have a
safe and efficient set of operating facilities, facilities
which continually evolve to meet the changing demands of the
new facets of science and technology. So our B&F program
involves a multi-year planning process, of requirements not
only for new facilities, but for facilities improvements and
for essential maintenance. And I want to describe these to you
by four examples.
First, we are, through the generosity of this Committee,
halfway through the construction of the new Clinical Research
Center. We're carefully planning the occupancy, for 2003, of
this wonderful, new modern hospital and clinical research
facility. We're excited by the great opportunities that
clinical research can provide to us through our modern
surgical, imaging and day care facilities.
But its activities must be and will be, through further
careful planning, fully integrated into the research programs
of the rest of the NIH intramural activities.
Second, as you heard the other day from Dr. Fischbach, we
will be creating a national neurosciences research center on
the NIH campus. This is needed because the area of neuroscience
is rapidly expanding through collaborations, to name but a few,
among basic neurobiologists, neurophysiologists, behavioral
scientists and neurochemists, along with clinical researchers
in neurology, neurosurgery, brain imaging and the sciences
related to addiction, aging, communications disorders and
ophthalmology. And there are many other areas as well.
We are asking to be able to have this new facility where
interactions can occur naturally and easily and where there
will be modern equipment, imaging facilities and laboratory
space that can be shared. We're requesting $47.3 million for
fiscal year 2001 and an advanced appropriation of $26 million
for fiscal year 2002 for the first phase of this neuroscience
center. It is going to provide us with opportunities for major
advances in many diseases: autism, mental illness, alcoholism,
drug abuse, Alzheimer's and Parkinson's disease, and
depression.
Third, our current central facility to house animals is a
one story complex which has long been outmoded and totally
inadequate to sustain the new technologies and needs of modern
American animal research. Animal models are becoming more and
more important to elucidate all aspects of human disease and to
develop new diagnostics and therapeutics. The fiscal year 2001
request is for funds to develop schematics and the design of a
central vivarium which will have a state of art modern animal
holding and quarantine facility.
Finally, fourth, in order to assure that our scientists and
staff throughout the NIH facilities, but particularly on the
NIH central campus, can perform their important duties and be
creative and productive, we must provide them with safe,
healthy, comfortable and efficient facilities. This is assured
through the general repair and improvements programs for
physical facilities and utilities and by the renovations as
needed.
The request for the buildings and facilities program is
$148.9 million.
With that, the presentations are completed, and my
colleagues and I will be pleased to answer questions.
[The prepared statement follows:]
Mr. Porter. Thank you, Dr. Kirschstein.
Dr. Collins has returned just this moment. Before I call on
him, I just want to say, Dr. Maddox, that was your first
presentation before this Subcommittee, if I am correct, is that
right?
Dr. Maddox. Yes.
Mr. Porter. Very, very impressive job. You did a wonderful
job. I'm very impressed with how you handled that. Thank you.
Dr. Maddox. Thank you, Mr. Chairman.
SEQUENCE OF THE HUMAN GENOME
Mr. Porter. Dr. Collins, why don't you join your colleagues
at the table. Dr. Collins, what I'd like you to do is to give
us your perspective on the dispute that apparently exists or
the discussions at least that have been underway for some time
with Celera and what you see might be happening in the future
with respect to those discussions.
Dr. Collins. Thank you, Mr. Porter. I really appreciate the
opportunity to appear as part of the OD presentation today and
clarify some of those issues, because I think they are quite
important.
First of all, let me say that I was personally stunned by
the decision of the Wellcome Trust to release this confidential
letter this past Sunday. I think that was a regrettable
decision on their part. I'm also disturbed and distressed by
the level of rhetoric that's appeared in the press over the
last two or three days about negotiations with a private
company called Celera. Those negotiations were between a group
of four of us representing the international sequencing
consortium and representatives of Celera Genomics Corporation.
We had hoped that these discussions would lead to a
collaborative outcome that would have satisfied Celera's
business needs but also benefitted the public.
Unfortunately, that was not the outcome. As a little bit of
background, informal conversations between the sequencing
consortium and Celera began back in October, 1999, leading over
the course of several months--with much time being devoted to
this by our busy genome center directors and by myself and by
Harold Varmus, acting as an advisor, not as NIH director, but
as a senior scientist--to a meeting that was held on December
29th with top executives of Celera to talk about a possible
model, where their data set, which they are producing with
their own funds, and the public DNA sequence information, might
be merged in a way that would be beneficial to all.
The model that we put forward, which we thought might well
be acceptable to them based on informal discussions, was that
the merging process would begin this summer, would extend over
the course of about three months time, and then would result in
a joint publication by both groups and release of the data into
the public domain for all to use.
I'm sure you know, Mr. Porter, because you've been a strong
supporter of this, that the need for access to the data has
been a cardinal principle of the Human Genome Project since its
outset. So we were very concerned to know if there would be any
limitations on access to this information.
Unfortunately at that meeting on December 29th, it became
clear that for business reasons Celera was not in a position to
have the access be as broad as our negotiating team felt it
should be. To be specific, Celera expected that this merged
database, which included roughly half publicly produced data
and half data that they had produced, would not be permissibly
used in any other commercial database other than their own.
Furthermore, they specified that it could not be used for the
generation of important research tools like DNA chips, because
that was also part of their business plan.
This came as somewhat of a surprise, particularly the part
about using this collaborative effort for things other than
databases, and the public consortium representatives felt
rather strongly that agreeing to these conditions would be a
betrayal of our responsibility to make this data available for
any scientist who has a good idea.
It seemed we were quite far apart at that juncture. Over
the course of two months, efforts were made to try to see if
there was grounds for continuing the negotiations. But there
was no real encouragement coming back from Mr. White, the CEO
of the parent company of Celera, that such negotiations were
going to be fruitful.
So in an effort to define the position that we felt put us
in a circumstance where we could not really go forward, a
letter was constructed from the four of us who had served as
negotiators, those being myself, Dr. Varmus, Robert Waterston
of the St. Louis sequencing center, and Martin Bobrow, a member
of the Wellcome Trust Board of Governors. That letter was sent
to the Celera team, basically outlining the points that we felt
we could not agree to and giving the reasons why. Virtually all
of those points surrounded the process of public access.
These are very important issues, and one of my concerns is
that the unfortunate rhetoric that's going on right now in the
press has clouded over the really important principles. This is
not just any old product, this is the sequence of the human
genome. This is our shared inheritance. This is the bedrock
information on which much of the future of medical research
resides.
To have that data restrained in any way, particularly to
have it restrained in a way that prevents many of the most
creative tools of the future from being developed by other
companies or academic institutions with good ideas, is an
outcome which we just could not agree to. That is the reason
that these collaborations did not succeed.
Now, I am happy to report that yesterday we did receive a
letter from Dr. Craig Venter indicating that there might still
be some grounds for re-entering those conversations. As Dr.
Varmus is in India, I have not yet had a chance to discuss this
letter with him and the other two negotiators. When that
opportunity arises, which will be soon, we will see whether
there are some possible grounds for re-entering those
conversations and if so, we will be happy to do so--but only
under the circumstance where we feel we've lived up to our
obligation for public access to this critical information for
all.
Mr. Porter. Thank you, Dr. Collins. Looking at this
situation, one would say, I think, isn't there an inherent
conflict here? You want to get the data into the hands of
scientists and the public, without charge, immediately, and
their interest is to get it into their hands only on their
terms and with costs involved. It seems to me, at the very
outset, what's there to negotiate about, except that I realized
there must have been some kind of an agreement regarding the
fruit fly genome where you did collaborate and where you did
combine data.
Can you kind of put that into perspective for us and tell
us why you thought there was a possibility of getting an
agreement in this instance?
Dr. Collins. That's a very appropriate question. With the
fruit fly, the sense, at the time of entering into that
collaboration a little more than a year ago, was that the value
of the sequence information itself as a commercial product was
much more limited. Hence, Celera was willing to agree to a
collaborative effort where our grantee, Gerry Rubin at the
University of California-Berkeley, would work with Celera using
two different but complementary scientific strategies to
assemble this sequence. Dr. Rubin had been working on this
sequence for three years and had already finished 25 percent of
the work, but this collaboration could make it go faster.
In that instance, perhaps because of the perceived lesser
value of the sequence itself as a product, Celera was willing
to enter into the collaboration with no strings attached as to
how that sequence would be used. In fact, this collaboration
specifically implied and insisted that the sequence would be
placed in Genbank, which is a database that everybody has
immediate access to with no strings attached.
We would have loved to work out a collaboration like that
for the human sequence. Those terms would have been entirely
acceptable and most welcome. But what has happened is, over the
course of time, I think the business needs of what is clearly a
commercial concern have become more prominent. What might have
been at the outset of the founding of this company an intention
to make the sequence itself available and to try to make money
by providing annotations of it, has gradually merged into a
different view--that the sequence itself also needs to be part
of their property.
That is reflected not only by this changed view in terms of
access to the data, but also by patent filing, which initially
had been projected by Celera as something that would be done
very sparingly, and in fact has been done on quite a large
scale. Understandably, in a business perspective, this may make
good sense. But having a monopoly on the human genome sequence,
while it might be a good business plan, is clearly not in the
best interests of science or the general public.
FRUIT FLY COLLABORATION
Mr. Porter. Dr. Collins, is it fair to say that in
reference to the fruit fly sequencing, what basically was done
here is that you purchased the data that Celera had developed,
sequences that they had developed from them? They must have
been paid something for all of this sequencing that was done,
is that correct?
Dr. Collins. No, actually, it was done as a collaboration
where they provided the funding for the sequencing they were
doing out of their own private sources.
Mr. Porter. They did? What did they get out of this?
Dr. Collins. They got a wonderful opportunity to work with
an experienced investigator who had already started down this
path and who was a fruit fly expert. They had the opportunity
to work with him on a daily basis, scientifically to see how to
merge these two very different sorts of data, which is
effectively a pilot project for what they wanted to do for the
human sequence.
Mr. Porter. But they got no compensation for this?
Dr. Collins. They did not get compensation directly for the
sequence they produced.
Now, I will tell you, they do have an intention of
providing a version of the fruit fly sequence with a lot of
other added value information attached to it and putting that
on a database that you have to pay to see. We have no trouble
with that.
Mr. Porter. But you have it already out in the public.
Dr. Collins. The sequence itself, the As, Cs, Gs and Ts, is
publicly accessible. Their commercial product in that instance
is not the sequence, it's other things attached to it.
SEQUENCE OF THE HUMAN GENOME
Mr. Porter. My final question, if I may. When you went to
these discussions with the four representatives and Celera,
were you authorized to enter into an agreement with Celera at
that point, or would you have had to bring that agreement back
to NIH?
Dr. Collins. Oh, absolutely we would have had to bring it
back.
Mr. Porter. You weren't prepared to contract at that time,
it was just a discussion, is that correct?
Dr. Collins. Right. We were there as the chosen
representatives of the 16 genome centers around the world that
are doing the majority of the work. The sequencing consortium
had basically felt that these four people could represent their
views. But we were there as negotiators without decision making
authority. If we had arrived at some sort of a model for
collaboration, we would then have brought it back to those 16
centers and to the funding agencies, which would be the NIH
most prominently, but also the Department of Energy and the
Wellcome Trust in the United Kingdom.
Mr. Porter. Given where you are today, do you see any
possibility of this discussion leading to an actual
collaboration on the human genome?
Dr. Collins. It's possible that some other more limited
model might be developed where we could agree to cooperate and
coordinate with the various aspects of the work. I think this
very close collaboration--where there would be a fairly open
exchange of data and co-publication of the results--seems, as
you have very articulately pointed out, to collide with the two
very different missions of the enterprise, and not, to my view,
to be all that viable.
I would be happy to find out otherwise, and we will
continue to explore that.
Mr. Porter. Well, if I may say so, it seems to me that what
the American public is entitled to is to have this data put
into the public stream of information, and for scientists to
have it readily available to them, which is exactly what you're
doing. Any means of disrupting that ready availability, it
seems to me, is counterproductive to the public investment.
Dr. Collins. I appreciate your saying so, Mr. Porter. I
want to reassure you that the public sequencing effort is in
very good shape. We are within a few months of having 90
percent of this sequence in working draft form and in the
public domain where anybody can use it with no strings
attached. We'll move on from that to close up all the gaps and
have the final coverage of all the human chromosomes by 2003 or
hopefully sooner.
Mr. Porter. Thank you, Dr. Collins.
Mr. Jackson.
OFFICE OF RESEARCH ON MINORITY HEALTH ADVISORY COUNCIL
Mr. Jackson. Thank you, Mr. Chairman.
Dr. Kirschstein, during last year's hearings, we began a
very extensive dialogue regarding NIH and its Office of
Research on Minority Health. This dialogue was prompted in many
ways by the IOM report that outlined many shortcomings within
the NIH organization as it relates to addressing minority
health and training issues.
The main outcome of this discussion was my proposal to
elevate the Office of Research on Minority Health to center
status. On issues of importance to NIH, such as the NIH
graduate school, among other issues, I am aware of the value
that the agency places on the advice of advisory councils. It's
my understanding, and I remember reading this, that the
advisory council to then-Director of NIH Harold Varmus, Nobel
laureate, NIH director, that the advisory council did not agree
with the director's planned development of an NIH graduate
school, and the agency has at least for the time being
abandoned the idea of pursuing the development of a graduate
school.
First, I have several questions for you regarding the
Congressionally-mandated ORMH advisory committee. What are the
qualifications for becoming a member of the Congressionally-
mandated advisory committee on research on minority health?
Dr. Kirschstein. I think in some ways Dr. Ruffin could be
better able to answer the question, but I will start. I think
the requirements are that they be scientists, and perhaps, I
don't know, do you have any lay people on your advisory
committee?
Dr. Ruffin. Most of the individuals on the committee are
scientists.
Dr. Kirschstein. The reason I raise the issue of lay people
is that there is a requirement for advisory councils to have
one-third of the members be lay members.
Mr. Jackson. Who makes the appointments, Dr. Kirschstein?
Dr. Kirschstein. The advisory councils are appointed by the
Secretary.
Mr. Jackson. They are appointed by the Secretary.
Dr. Kirschstein. But in the case of Dr. Ruffin's advisory
committee, there was not, I didn't think, but I didn't remember
quite, that's why I asked him, a requirement that there be lay
people. So the individuals are scientists who work in various
areas of science, most of whom either have worked in
specifically minority educational institutions that do
research, or majority educational institutions where they have
had interests in minority activities and many of them have run
training programs for minority scientists.
CENTER PROPOSAL FOR OFFICE OF RESEARCH ON MINORITY HEALTH
Mr. Jackson. What if any advice has the committee provided
to the NIH Director regarding the status of ORMH?
Dr. Kirschstein. The Committee has met several times. In
its first set of meetings, as I recal--and I attended all those
meetings although I may not have stayed for the entire meeting,
when I was Deputy Director--they were learning a great deal
about the activities of the ORMH. The Committee then began to
advise Dr. Ruffin specifically on what might be important
programs.
In regard to your question as to whether that committee was
specifically asked to review your center proposal, it did
eventually do so, but it took some time. It did it at its last
meeting and maybe the meeting before. And actually sent several
letters to NIH about it.
Mr. Jackson. Yes, I am aware of the advisory committee on
research on minority health and all the members of the advisory
committee signed a resolution in support of elevating the
Office of Research on Minority Health to the level of center
status. I'd like to submit this for the record, also, to
provide Chairman Porter with a copy, as well as other members
of the Committee.
I was just wondering, it appears that when the advisory
council indicated to Dr. Varmus that they disagreed with his
idea of creating an NIH graduate school, it appeared that the
Director of NIH followed the advisory committee's advice. But
when the advisory committee for the Office of Research on
Minority Health offered its advice that therefore, we
unanimously support H.R. 2391 to elevate ORMH to center status
as one step in increasing the focus on investment in reducing
the continuing disparities in minority health status and
minority research training, I'm wondering what was NIH's
response to the advice it received from the Congressionally-
mandated advisory committee on research on minority health
regarding the status of ORMH?
Dr. Kirschstein. Mr. Jackson, I cannot tell you
specifically what the response was. What I can tell you, and
I'm not using this as an excuse, is that when legislation is
introduced, it is the position and must be the position of all
the agencies under the Department of Health and Human Services,
to ask what the Department's position and the Administration's
position is in regard to specifically supporting such
legislation.
Mr. Jackson. I can understand that. But certainly, I would
imagine that those advisory committee members, Ph.D.s, M.D.s,
all the scientists that you have suggested have obviously
acknowledged that the Office of Research on Minority Health is
worthy of such elevation, they go on to say that organization
elevation alone will not be enough. That's pretty
authoritative.
Authority to grant priorities, to direct grant priorities
to disparities in minority health with the appropriate
increased funding resources to support it is clearly needed for
the proposed center to succeed. They conclude, we expect that
this additional funding should supplement and not supplant
existing institute-specific activities.
The reason I'm raising this concern, Dr. Kirschstein, while
I've simply tried to codify some of the concerns that they
feel, the advisory committee, are problematic and existing at
NIH already, it didn't require Congressional legislation for
then Dr. Harold Varmus to consider elevating or creating a
graduate school at the agency. And obviously, if he was going
to create such a graduate school at some point in time it would
have required Congressional legislation to fund such a graduate
school.
So there was certainly some activity occurring under Dr.
Varmus' leadership that would have created a graduate school
that would have ultimately led to legislation. And I simply
have legislation that might be on, I actually think it's on the
back side of activity that's already taking place over there on
these questions. But that notwithstanding.
I do have a couple more questions, Mr. Chairman. I have a
report from the U.S. Commission on Civil Rights dated September
1999. This report is entitled Health Care Challenge,
Acknowledging Disparity, Confronting Discrimination and
Ensuring Quality. At a minimum, I recommend that each member of
the Subcommittee read the level of transmittal and summary.
I have yet to complete all my review, but what stands out
most to me are not only the laudatory comments about the Office
of Research on Minority Health, but also the recommendations to
elevate the office to center status. In fact, the report
references my proposed legislation.
There are eight findings and recommendations related
specifically to ORMH. I'm wondering, Dr. Kirschstein, one, are
you familiar with this document?
Dr. Kirschstein. Yes, indeed. I participated in discussions
with the Civil Rights Commission, as did Dr. Ruffin and many
other members of my staff. I was deeply involved, and I think
if you'll read that report carefully, they will talk about the
various activities which I was involved in which they found
laudatory.
Mr. Jackson. I'm really interested in this. We have
scientists on the one hand who are saying, elevate the Office
of Research on Minority Health to center status, we have a
former director of NIH that doesn't need the support of an
advisory council in order to create a graduate school, but
followed the advisory council's advice to not create a graduate
school. But when I asked about elevating the Office of ORMH to
center status, you indicated in your previous answer that
somehow, we're waiting, that it requires some approval or
something from the Secretary or the President. Help me
understand that.
Dr. Kirschstein. What I'm explaining to you is what was the
situation. That when specific legislation has been introduced
into Congress, as you have done, it is the Department's
position that its agencies are not to support or provide lack
of support to such legislation until such a time as the
Department has a position. Mr. Jackson, if I may.
Mr. Jackson. Yes, ma'am.
Dr. Kirschstein. The issue, I think, of what's gone on this
past year is something that happened and I would like to say we
should move on. And I hope we will. We are already in the
process of developing a center within the Office of the
Director, because that's the only authority we have by which we
can do that now. We cannot unilaterally establish an
independent center as are the Institutes and other centers
without some sort of authority.
I agree with you----
Mr. Jackson. But let me say, Dr. Kirschstein, that, Mr.
Chairman, I have enormous respect for the outstanding work that
Dr. Kirschstein has done, and I could not possibly begin the
process of even coming close to challenging her commitment to
this. And I also want to congratulate Dr. Ruffin and all of you
who have been through a very lengthy hearing process with me on
some questions that I've been raising.
Mr. Chairman, I have examined and queried across the NIH
and I must tell you that there is definitely the spirit and
commitment to address some of the fundamental concerns that
exist at the NIH. What I am suggesting now is that at the level
of the Secretary and at the level of the President, we are
still at loggerheads on the appropriate policy to pursue. And
while I cannot hold these institute directors responsible, that
our legislation is raising some very important questions at the
level that should be answered at the level of the Secretary and
answered at the level of the President.
So I want to thank you, Dr. Kirschstein, and all of the
centers and directors at NIH who have put up with me through
this period, and I want to thank all of you once again for the
outstanding work that you continue to do. I suspect next year
when we sit down again hopefully we will have made significant
progress on what Dr. Maddox has presented for us today.
Thank you, Dr. Kirschstein, and thank you, Mr. Chairman.
Dr. Kirschstein. I want to thank you, Mr. Jackson. I think
you've clarified our thinking a good deal. What we want to do
now, before the inception of the 2001 budget, is to work to
establish a center so it will be a jump start for what we do
when we start fiscal year 2001 and, of course, when we present
the fiscal year 2002 budget, which will have the plans and the
fiscal aspects based on the strategic plan.
Thank you very much.
Mr. Jackson. Thank you, Dr. Kirschstein. Thank you, Mr.
Chairman.
AIDS CLINICAL TRIALS
Mr. Porter. Thank you, Mr. Jackson.
Dr. Nathanson, in your presentation you talked about an
AIDS vaccine trial that's going on with animal models. Is there
not one also going on with humans?
Dr. Nathanson. The clinical trials in humans, Mr. Porter,
are phase I, which is safety, phase II, immunogenicity, and
then phase III, are efficacy. There are and have been many
phase I and a number of phase II trials being conducted. There
is currently a phase III trial that is mainly supported by
VaxGen, a private company.
But in addition to that, we are heading into a decision
whether or not to start another phase III trial, and with a
recent meeting about 10 days ago, meeting, but I know the
essence of it, where a plan for a phase III trial, another
phase III trial of a fairly promising product, was discussed in
some detail. That will come to a decision, and if it's a
positive decision, probably move forward to begin in another
year or so.
Just for your information, that's what's called a prime and
boost regimen, where you start with a recombinant virus that
contains some of the genes of HIV incorporated in an attenuated
pox virus, similar to vaccinia that was used for vaccination
but attenuated from that. Then there's a protein boost, that
boosts the antibody response.
And that's looking fairly promising, although there's some
discussion in the scientific community as to how promising it
is. But my guess is that will probably move forward to a phase
III trial. So that will be a second phase III trial.
But meanwhile, many other things are being tried for
immunogenicity in phase I and phase II trials.
AIDS VACCINE
Mr. Porter. When Dr. Fauci was here, and I'm asking you to
confirm it or correct me, my understanding was that the
knowledge that we have of the HIV virus is such that because it
mutates or changes, that you can't develop a vaccine like a
polio vaccine to eradicate the disease. All you can develop,
and likely will be able to develop, is a vaccine like the flu
vaccine where you have to change the vaccine each year or so in
order to try to anticipate the mutation of the virus. Is that
correct or not?
Dr. Nathanson. Well, this is my personal opinion, I don't
know exactly what Dr. Fauci's view would be, that it is true,
this is a virus that does change and mutates quite rapidly. But
in fact, the problems in developing the vaccine are in a sense
more profound than that. I will only mention one aspect just to
give you an idea.
With polio or many of our other viruses, people who are
naturally infected develop what we call neutralizing
antibodies. That means antibody in the blood serum that will
inactivate the virus. And then it's relatively easy to
replicate that with either a live attenuated or an inactivated
version of the virus. In fact, Dr. Kirschstein and I both
worked many years ago on the polio vaccine in that respect.
And with the AIDS virus, people who are naturally infected
develop antibodies. But those antibodies do not inactivate the
virus, they don't neutralize the virus. And it's been very
difficult to make a candidate vaccine which produced that
neutralization even against the virus that you started out
with, so you didn't have to worry about antigenic variation.
So we have problems even before you get to the issue of
antigenic variation. This virus has been a peculiarly difficult
one to develop a vaccine for, for basic biological reasons.
That's only one of them, actually.
U.N. AIDS
Mr. Porter. I know this is not a fair question, but you
might have some information that we don't have. You raised the
question of the terrible situation in Africa and other places
in the world. The President proposed earlier this year or maybe
late last year a very significant contribution by the United
States to UNAIDS, I believe it was $1.3 billion.
Do you know the status of that whole situation?
Dr. Nathanson. I don't, actually. One of the things we did
look into as a follow-up to the discussion you had with Dr.
Fauci was the deployment of Nevirapine for perinatal
transmission. Actually, we've talked to Brooks Jackson, who is
the professor at Johns Hopkins who did the Nevirapine trial in
conjunction with his colleagues in Uganda. He had just returned
from Uganda, so I can give you a little more information.
Because that would be an example of an immediate application.
Uganda is not a country which is generically opposed to the
use of Nevirapine. The main issue is that they simply don't
have the resources to apply it widely. They are probably going
to do some pilot projects, particularly in Kampala, the
capital, where the main medical school is located and where
most of the research takes place.
But they have calculated that to apply this regimen to the
whole country would cost about $10 million. They don't have
those resources. And less than 10 percent, it turns out, would
be for the price of the drug itself. They would start with a
population in which there are about a million pregnancies every
year. Of these, approximately 160,000, about 16 percent, are
women who are HIV-infected. Of those 160,000 births in infected
women, about 40,000 would be infected babies. Nevirapine
potentially could reduce that 40,000 by half to about 20,000.
This just gives you a sense of the numbers.
But in order to do this, they would have to do voluntary
counseling and testing on an individual basis for all the
million women and then go on to test them individually. Those
who are tested would have to be counseled again about
Nevirapine. So there's a lot of ancillary expenses which turn
out to be about 10 times as much as the drug itself. The truth
is that they don't have the money to do this. But also, they
probably lack the infrastructure to do this. Because their
medical infrastructure is rather minimal at present.
But that is a potential application. We also did query the
folks at CDC who are much more involved with this deployment.
Because this is not research, it's sort of deployment. They
knew of no immediate plan to use any of the money that the
President has talked about for this purpose. We certainly would
think, if I can say so, that this would be an appropriate use
of some of those funds. Because that's the most immediate
intervention that we're aware of in countries that really don't
have the infrastructure to support therapy.
I just wanted to expand on that because I knew you were
very interested in the Uganda situation, from your questions to
Dr. Fauci.
Mr. Porter. That would be a bilateral intervention,
presumably.
Dr. Nathanson. Oh, yes.
Mr. Porter. Not through UNAIDS, is that correct?
Dr. Nathanson. Well, it could be done by either the leading
public health people and medical researchers in Uganda, some of
whom I know quite well, would be very pleased to interact with
any agency that came forward to support that.
Mr. Porter. I understand. What I'm asking really is, would
you be confident if we worked with the UN agency and worked
through them?
Dr. Nathanson. Oh, yes. We're on very close terms with
Peter Piot, who heads UNAIDS. Frankly, they are underfunded but
they have some very competent, very dedicated people at UNAIDS.
I think they would be very capable of playing a major role in
all this. Yes.
BECON
Mr. Porter. Thank you, Dr. Nathanson.
Dr. Maddox, Dr. Baldwin is doing a great job with BECON,
the bioengineering consortium. There was language in the report
accompanying the bill last year talking about creating an
office first, with the thought that a thorough review would be
made discussing the potential of creating an institute of
bioimaging and bioengineering. Can you give us the status of
all that and what the latest thoughts are?
Dr. Maddox. Yes, Mr. Porter, we have begun to really look
at the Office of Biomedical Engineering and Bioimaging very
carefully. Dr. Baldwin, who is here with us today, has assured
us that she has now begun to look at establishing a position
description to hire someone to actually run the office. As you
may recall, we had $200,000 put in the fiscal year 2000 budget
to sort of get the idea off the ground and started. And in
terms of fiscal year 2001, we are also expecting to put
additional funds in there, pending the outcome of the budget
process.
But we are underway to getting the office established. We
are looking now to put some personnel in place. Dr. Baldwin has
someone working in her office now to sort of get this off the
ground and running before the time we can actually hire
someone.
Also, I should add that the BECON effort, which is an
effort that's been ongoing, would be one of the aspects that
this office would take under its consideration and would be
coordinating. I'm wondering if Dr. Baldwin had anything she
wanted to add.
Dr. Baldwin. The establishment package is moving forward. I
hope to have the search underway shortly. The community, as you
know, AIMBE has been very supportive and very helpful in this.
And what we'd like to do is make sure we can build on the
accomplishments of BECON which we've really tried to construct
in a way that is an additional help to the Institutes, as
opposed to being competitive with the Institutes.
I think that is essential for an office like this. For the
office to really make the most of what we can do in
bioengineering, it needs to work with the Institutes and
Centers. Certainly the bioengineers have been very happy with
the outcome of the BECON initiative so far, and the growth in
support for bioengineering. So we're cautiously optimistic.
Mr. Porter. Where does the $200,000 come from? From the
Office of the Director?
Dr. Kirschstein. Office of the Director.
Mr. Porter. Is $200,000 enough?
Dr. Baldwin. It's enough for this year because we won't
have the office up and running until the end of FY 2000. Even a
new Director, hired this year, probably wouldn't come on board
until the end of the fiscal year. So the $200,000 is fine for a
startup level. That was never intended as the ongoing level for
that office.
But the office was not intended to be a granting office. It
was to provide an institutional home for the activities of
BECON, and the bioengineering research would stay in the
Institutes.
Mr. Porter. Thank you, Dr. Baldwin.
Dr. Maddox. Mr. Porter, our estimate in the President's
budget for 2001 would be that we would need about $1 million
for that office in 2001.
REFORM OF THE PEER REVIEW PROCESS
Mr. Porter. All right. I think that Dr. Katz began talking
about this when I came in the room, but I'd like, Dr. Maddox,
if you would tell us about the reform of the peer review
process. Where are we in all that?
Dr. Maddox. Through the period of time that Dr. Ellie
Ehrenfeld has been on board as the Director of the Center for
Scientific Review, indeed, peer review has undergone a lot of
changes. As you might recall, when Dr. Ellie Ehrenfeld came on
board, the Center for Scientific Review at that time was called
the Division of Research Grants. But with the arrival of Dr.
Ehrenfeld, she not only looked to giving the office more
visibility and sort of raising the stature of the office, as
well as the employees associated with it, but also she began
looking at the structure of the study sections.
At this point in time, we have completed the rearranging
and the restructuring of the neurosciences study sections.
We've completed the reorganization and restructuring of the
AIDS study section. And at this point in time, you may have
heard of Dr. Ellie Ehrenfeld's report, the first draft of this
report that we've termed the Boundaries report, which again is
looking at a more formal reorganization and perhaps assessment
of all of the study sections, not just the ones in the
neurosciences or the AIDS arena.
In particular, there's been a lot of interest in the
community at reorganizing and restructuring study sections
based on diseases and disease entities, as opposed to
scientific areas. So the first phase, the first report of the
Boundaries committee is out, and I believe that the second
phase is underway.
SCIENCE EDUCATION ACTIVITIES
Mr. Porter. Thank you. You talked about science education
activities funded through the Office of Science Education. How
do those differ from the activities funded through the science
education partnership award program within NCRR?
Dr. Maddox. Actually, Mr. Porter, all of the ICs really
contribute significantly to the activities of the Office of
Science Education that come out of the Office of the Director.
You may recall in looking at our budget figures that the budget
for the Office of Science Education is very slim, it's slightly
over $3 million. So, much of the activities that we have
undertaken within the Office of Science Education is through
collaborative efforts.
In fact, the supplement program that I spoke of earlier is
a program in which three Institutes get involved in the
supplement series. And it's through their funding and
collaboration with Dr. Fuchs and his staff that we're able to
move these programs along. The budget of the Office of Science
Education would not allow us to conduct these types of studies.
As we talk about the program that comes out of the NCRR,
again, that program is supported in collaboration with the
Center, as well as with the Office of Science Education. So the
minimal amount of funds that come out of the Office of the
Director are mainly for staffing and for some small support for
resources. But the bulk of the funds that come to these
programs, and to developing these programs, are in
collaboration with the Institutes and Centers.
Dr. Kirschstein. Mr. Porter, in addition, both the Office
of Research on Women's Health and the Office of Research on
Minority Health contribute to those programs.
CHILD CARE FACILITIES
Mr. Porter. Dr. Kirschstein, since you did the buildings
and facilities yourself, I have one question. My understanding
is that there is a joint child care facility being constructed
in the research triangle park with NIEHS and EPA. I wonder, in
the original design, was this child care facility included in
the original design of the EPA facility? What's the total cost
of it, and how much is EPA contributing to it?
Dr. Kirschstein. I'm going to ask Mr. Ficca to answer that
question.
Mr. Ficca. This child care facility will replace the child
care facility supported through a lease. The collaboration with
EPA was to share the cost. The money that's in our budget is
only the NIH portion. I am not sure that I can give you the
exact figure that EPA is contributing to that. But I would be
happy to provide that for the record.
[The information follows:]
The Research Triangle Park child care faciltiy was included
in the original design of the EPA facility. At the time of the
design, the capacity of the child care facility was only
projected for 100 children in 9,900 GSF (6875 (NSF) of space at
a cost of $2 million (EPA's contribution to the facility).
Since then, the projected need for child care has increased to
180 children. The NIH Buildings and Facilities request for
funds of $1.6 million raises the total funds required to $3.6
million and the building space to approximately 18,000 GSF.
Mr. Porter. Another question, while you're there. There's a
request for $500,000 for a child care facility on the Bethesda
campus. How would this facility compare in size to the one in
North Carolina?
Mr. Ficca. The proposed child care facility on the Bethesda
campus, what is called the northwest temporary facility, will
replace an existing temporary facility on campus. It will house
approximately 100 to 120 children. The one shared by the EPA
and the National Institute of Environmental Health Sciences is
about the same size. I can provide the approximate size of the
Bethesda facility for the record as well.
Mr. Porter. I would appreciate your doing that. Thank you
very much.
[The information follows:]
The initial request of $500,000 is only for the design of
the new child care facility on the NIH Bethesda campus. This
facility is planned to be approximately 20,000 GSF.
Mr. Porter. I want to thank all of you. In fact, Ruth----
Dr. Kirschstein. Mr. Chairman, may I make a final
statement?
Mr. Porter. Certainly.
Dr. Kirschstein. On behalf of all of us, in closing these
sessions, Mr. Porter, my colleagues and I, in particular, want
to thank you for your support and efforts on behalf of
biomedical research, which have been of so much importance to
improving the health of the American people, and in fact, the
people of the world. We wish to present you with a framed
photograph that was taken several weeks ago, and we want to
rise and salute you.
[Applause.]
Mr. Porter. Ruth, that is really special. I had no idea you
were going to do this.
I've said it many times before, but let me say again that
the work that is done by all of you, all the people at NIH, the
whole community, is of such great importance to all of
humankind. We think of it as the American people, but it's
really the whole world. We just feel that our role is to give
you all the support we possibly can to further the wonderful
scientific opportunities that are now available to help to
conquer disease.
For me, during all the 21 years I've been on this
Committee, I have found such fascination and inspiration with
what has been done at NIH, the research that has gone forward
and the progress that has been made, that to me, I think if
every member of Congress were able to hear what I've heard,
they wouldn't have one moment's hesitation in saying that this
is the best spent money anywhere in Government, that it
furthers the interest of human beings everywhere, and that it
ought to be increased as rapidly as we can possibly increase
it, so that the discoveries that are waiting to be made can be
brought on-line faster.
So everything that you do is, I think, done so well, so
thoughtfully, there's so much intellect that goes into every
aspect of NIH. I have just felt that the NIH story needs to be
known by more people. I know you're working on it. [Laughter.]
It is so fascinating and so compelling, and so inspiring.
In a time when the news is often so negative, we need the
inspiration that NIH provides us.
This picture will have the most honored position in
whatever office I have next year. I can't tell you how much I
appreciate the association, the friendship and the sharing of
values that I think all of us have, both on this side of the
table in this Subcommittee and on that side in terms of the
interests of our country and all human beings.
So thank you for this, it's so special to me. I really
appreciate it. Thank you so much.
The Subcommittee will stand in recess until 10:00 a.m.
tomorrow.

WITNESSES
STEPHEN E. STRAUS, M.D., DIRECTOR
RICHARD NAHIN, PH.D., DIRECTOR, OFFICE OF EXTRAMURAL PROGRAMS

CHRISTINE HOLLINGSWORTH, FINANCIAL MANAGEMENT OFFICER
RUTH KIRSCHSTEIN, M.D., ACTING DIRECTOR, NIH
DENNIS P. WILLIAMS, DEPUTY ASSISTANT SECRETARY, BUDGET, DHHS
Opening Remarks
Mr. Porter. The subcommittee will come to order. We
continue our hearings with the National Center for
Complementary and Alternative Medicine. We are pleased to
welcome, for the very first time, Dr. Stephen Straus, the new
Director.
Dr. Straus, I apologize to you that the first Institute
went so long this morning. We will allow extra time. We are
very anxious to hear what you have to tell us.
Dr. Straus. Thank you, Mr. Chairman.
Allow me, first, to introduce, on my far left, Dr. Richard
Nahin, the Director of our Extramural Program; to my immediate
left, Ms. Christine Hollingsworth, our new chief budget
officer; and, of course, Dr. Kirschstein, who has been a great
adviser, and who has been very accessible in helping me grow
into this position.
Thank you. It is an honor to appear before the subcommittee
for the first time. Let me say, as Dr. Hyman did, that my
pleasure is tempered by the fact that this will be my one
opportunity to appear before you in your period of truly
inspiring leadership of the subcommittee.
Mr. Chairman, and members of the subcommittee, the very
establishment of the National Center for Complementary and
Alternative Medicine, a little over a year ago, is testimony to
the extraordinary, growing interest of the American people in
the opportunities that complementary and alternative medicine
appear to hold for them. By many estimates, over 40 percent of
Americans today are using one or more such modalities with the
belief and expectation that it will sustain and improve their
health. It is unfortunate that they do so, however, without the
guidance of a true evidence base that the American public needs
and deserves to help in their selection of these modalities. It
is the challenge to provide
that evidence base that energizes both me and my new colleagues
in the Center to help apply the well-established tools of
excellent and rigorous research.
[The information follows:]
STRATEGIC PLAN
Dr. Straus. We have begun our efforts by developing a
strategic plan. I have outlined for you on the display board to
my left the cardinal priorities that guide our approach to
succeeding in this area. First and foremost, as with all NIH
Institutes and Centers, is our investment in research. In this
context, this is research of the highest standard. It is not
the generation of additional anecdotes, but true solid
evidence.
Because ours is a new scientific venture, addressing a very
ancient and venerable series of practices, we need to invest in
training of investigators to seduce them, as Dr. Hyman said,
into joining our field and sharing with us the excitement and
opportunity that it represents.
We need to articulate to the American public, in a very
clear way, the results of our research findings; to reach out
to our many stakeholders and constituents and explain to them
what works and what does not work, what is safe and what is not
safe. The end result of our research should provide the kind of
evidence that will allow the seamless integration of those safe
and effective practices into the daily practice of medicine in
the United States today. Finally, in our strategic plan, we are
cognizant of the responsibility that we bear to steward the
resources you have placed in our hands.
It is this strategic plan that guides the diverse research
portfolio that we are in the process of developing. That
portfolio extends, on the one end, from novel and unbiased
investigations of modalities that the public has great interest
in, but for which there is, in fact, very little or no
scientific support, such as magnet therapy and energy healing.
On the other end of the spectrum, we extend to the largest and
most definitive randomized trials ever conducted of
complementary and alternative medical modalities. I will
illustrate one such study for you to show how our philosophy
bears on this approach.
DEPRESSION
Dr. Hyman introduced the area of depression very well, and
the ability to address depression with powerful synthetic
drugs. This is an opportunity that we, in NCCAM, can address as
well, because ancient herbs, such as St. John's wort, are
widely used with the expectation that it sustains mental
balance and improves mild to moderate depression. We are
mounting a definitive study in collaboration with Dr. Hyman and
his colleagues, and with the Office of Dietary Supplements,
just as we mount all of our large studies in collaboration with
the other Institutes, Centers and health agencies, we are
mounting a definitive study.
[The information follows:]
Dr. Straus. I show you two pieces of data here that provide
the important backdrop for this study. Data from the British
Medical Journal, from this past November, show the results of a
randomized trial in which patients with depression were treated
with St. John's wort, or with an old mainline tricyclic anti-
depressant, Imipramine, or with a placebo. As Dr. Hyman
indicated, this was a typical brief 6-week anti-depressant
study. Here, we are showing the improvement in depression with
St. John's wort as comparable to that with Imipramine, and, in
both cases, superior to that of placebo. Thus, St John's wort
is a natural product which appears to be active. The study we
are mounting, together with NIMH, is substantially larger and
is a 6-month study. We can address efficacy and safety in ways
that represent a new standard for the field.
[The information follows:]
If we expect these agents to be active, they should, as
well, have potential risks; we need to address these as well.
They are illustrated here with data from my colleagues at the
NIH, published in the Lancet on February 12th, where volunteers
were given the highly active and important HIV protease-
inhibiting drug, Indinavir.
[The information follows:]
Dr. Straus. It sustained a high blood level, shown in
green, and that level exceeds the threshold, the dotted line,
that one needs to successfully inhibit the growth of the virus.
It does so routinely in people, and that is why it is a great
drug. When St. John's wort, in standard dosage, was added to
the Indinavir treatment, it so sped up the body's metabolism of
Indinavir that it reduced the blood levels tenfold, to a level
that is no longer therapeutic for HIV.
NEW RESEARCH PRIORITIES
We have to appreciate the opportunity and the challenge,
and that is what guides our research portfolio. In addition to
studies like that of St. John's wort other large clinical
trials, our new priorities for the year 2001 are listed in this
next display panel.
[The information follows:]
Dr. Straus. First, we are expanding rapidly our investment
in investigator-initiated research, the jewel in the crown of
the NIH research portfolio. We will increase by approximately
threefold the number of such investigations we fund from 1999
to 2001. Because so much of complementary and alternative
medicine has arisen in the context of many indigenous peoples
and cultures over the millennia, we have a special privilege
and opportunity in NCCAM to conduct our research, and at the
same time address issues of health disparities. We will speak
more about that issue.
As I indicated, one of our goals is to have successful data
lead to successful integration, and we will be performing
studies of the barriers that prevent physicians from taking on
new ideas and integrating them into their practice, as well as
the tools that facilitate that process.
We will be mounting, in 2001, a new large definitive trial,
like the St. John's wort study, of an ancient herb known as
milk thistle or Silybum marianum, which is long believed to
treat cirrhosis and chronic hepatitis. We and NIDDK held a
workshop this past fall which coalesced the preliminary data,
saying that the time is right for such a study.
Finally, we are now building our own intramural research
program, guided on a large clinical research emphasis. We
believe that the unique and rich environment of the NIH
Clinical Center and the new, Clinical Research Center, that you
are permitting us to build provides an opportunity to us to do
unparalleled research, and for us to bring to NIH itself the
concept of integration of successful CAM therapies.
It is my belief that this approach will make NCCAM the
international leader in applying rigorous scientific tools. We
have a bully pulpit to occupy, to spread to the American public
the word that science can help provide them definitive answers.
The tools of science will permit medicine in its virtual
and longstanding dynamic process to evolve, to change, and to
integrate the best practices, while the data will be so clear
that an informed American public will embrace the best of them.
They will reject those practices that are marketed to them
today, which are neither safe nor effective.
Thank you. I am happy to take your questions.
[The written statement of Dr. Straus follows:]
SETTING RESEARCH PRIORITIES
Mr. Porter. Thank you, Dr. Straus.
Your mission is different from almost all of the
Institutes, because they are working to develop a base of
knowledge that leads to new discovery. While that may be a part
of your portfolio, the main part is that there are already, on
the market, many different alternative therapies We do not know
whether they are safe or efficacious; we do not know that they
may have drug interactions, that may be dangerous, or that they
make other drugs less efficacious.
I guess that the end product of what you do will be to
integrate certain nontraditional therapies that are found to be
safe and efficacious into the traditional therapies, and to
expand the base of what is available and effective for people
to address health problems.
The first question I have is how do you determine where to
start? Because there are so many different things out that are
on the market already. What gives you a look at what you ought
to be doing? Do you try to balance those that may have positive
therapeutic and safe advantages against those that you worry
that the public is buying that are either unsafe or
nonefficacious?
When you find something that is unsafe or nonefficacious,
how do you change behavior in the marketplace? How do you get
that information across to people so that they will not waste
their money or endanger their health?
Dr. Straus. Thank you, Mr. Chairman. Those are excellent
questions.
Our prioritization, of course, is complex. There are at
least 1,500 different herbs, not to mention other biologicals,
chemicals, natural products, energy-healing systems, massage
therapies and body work, and spirituality. It is a huge buffet
to choose among.
Our prioritization is based upon a number of
considerations. First and foremost is which of these modalities
are used the most by Americans today? Which have the potential
to address the most important public health problems? So our
modalities are towards diabetes, mental health, cancer, and
heart disease. Our priorities, in terms of the disease areas,
are the same as those of the other Institutes, because we know
the public health message is important.
We invest the largest amount of our energy and funds in
those areas that seem, at this time, to be the most promising,
like the preliminary data from the St. John's wort study,
because the American public deserves definitive answers sooner.
At the same time, we invest lesser amounts in exploratory
studies to create a pipeline that will explore things that are
more novel, for which there are little preliminary data. This
entire analysis is not done by sitting in our Offices in
Bethesda, but through the context of a constant dialogue with
the American public, with patients, with their advocates, with
members of industry, advocacy groups around specific diseases,
and our advisory councils.
I had the pleasure of addressing our Council for the first
time on January 24th; I shared with them our prioritization,
and their feedback was a very important, and instructive
process for me.
The results of this investigation, as you correctly said,
Mr. Chairman, will have two potential outcomes. It will either
show that something is effective or it is not. Frankly, if
everything we do proves ineffective, no one will believe our
message. In all honesty, one of our strategies for starting
with things for which there is good evidence today, is to
provide successes which will build trust with the American
people, their advocates and our many constituents.
If we give clear messages in an unbiased and scientific way
that this works, but this does not, they are inclined to
believe both of them. Because these products are in the
marketplace, there may still be individuals who will have the
freedom to choose what they wish. However the message from
science can be a strong and effective one. Let us witness, for
example, the change in demands for Laetrile 15 to 20 years ago,
when many individuals were clamoring for it. Very good studies
suggested, in fact, that it was not effective. There are still,
today, people who seek and use Laetrile, but the number is much
smaller. I think our message can have an impact on the public
use.
Mr. Porter. Thank you, Dr. Straus.
Ms. Lowey.
DIET AND EXERCISE
Mrs. Lowey. Thank you, Mr. Chairman, and welcome Dr.
Straus. We wish you great success, as another New Yorker, even
though you grew up in Brooklyn. I will not take too much time
for that. [Laughter.]
This is an Institute that has interested me for a long
time, and I look forward to working with you because I think it
is so very important for the public, for all of the reasons
that our distinguished Chairman mentioned.
In several of these hearings, we have been talking about
diet, exercise, the confusing messages that have come out:
drink a glass of red wine, do not eat the pasta, better to have
fats and bacon, et cetera. I think most people do agree that we
should exercise a few times a week and that Snickers and candy
are not good for you.
But the messages really are very confusing. And I wonder to
what extent this Institute will be focusing on diet and the
connections between that and good health. I would be interested
in your comments.
Dr. Straus. Thank you.
First of all, Mrs. Lowey, let me say it is a pleasure to
testify before you, and I look forward to establishing a
relationship with your office. In sharing our experiences, my
mother was born in the Bronx. [Laughter.]
The issue of diet and exercise is a very important one to
public health today. Fortunately, Americans are changing their
practices, and it is for that reason that the mortality from
cardiac disease has decreased as much as it has. Our young
people are getting the message better than before, but it is
still not adequate.
The importance of diet and exercise are agreed upon by
public health authorities and physicians. While we in NCCAM
speak to the very same message, diet, merely for the sake of
weight loss is not a high imperative for our research portfolio
because that is so well-integrated into studies by NIDDK and
others Institutes.
Mrs. Lowey. Which diet?
Dr. Straus. Ah.
Mrs. Lowey. You see, it is the contradictory messages.
Dr. Straus. Thank you.
Mrs. Lowey. And I refer to the panel and the discussion at
the Department of Agriculture, when you had Dr. Atkins on one
side, Barry Sears on the other, Dean Ornish, I do not know,
someplace in the middle. I guess he would be on the other side.
Dr. Straus. There was an interesting debate among them. In
the context of normal diets, low cholesterol, and low fat, I
think we can agree with the limitation of calories. You are
correct. There are extreme diets, and fad diets, and diets that
incorporate the use of additional botanical products and
supplements to help speed weight loss. Those are areas that we
can address and invest in, and we do so.
One of the issues related to diet, in fact, that bears on
the Chairman's question as well has to do with the use of
herbal and metabolic products along with diet, such as ephedra
to speed weight loss.
Mrs. Lowey. What is that in picolinate [ph.]? Something
like that.
Dr. Straus. I am sorry?
Mrs. Lowey. Picolinate or that is in almost all of these--
--
Dr. Straus. No, that is chromium.
Mrs. Lowey. Chromium.
Dr. Straus. Yes.
Mrs. Lowey. But there is a second word, ``chromium''----
Dr. Straus. Picolinate.
Mrs. Lowey. Right.
Dr. Straus. Yes. Thank you.
Ephedra, a botanical that speeds metabolism, it is a drug
like amphetamine, actually, and its chemical composition is
used for diet. That is something we are interested in studying.
In fact, I met recently with Mr. Levitt from the FDA. His group
is charged with looking at all of the incidents of serious
toxicity from long-term ephedra use in otherwise healthy young
individuals. Chromium is important in its use in diet, both
because it is said to ``burn fat,'' as well because of claims
that it balances the body's use of sugar and sugar metabolism.
We are developing a program, together with Dr. Alan Spiegel and
his colleagues in NIDDK, to mount some studies of chromium for
its effect on diabetes and diet.
There are many dietary areas that do fall within the
context of critical public health issues to which we can
address our resources.
Mrs. Lowey. How high a priority is it? Because we hear, and
we discuss this probably because so many of our personal
experiences bear on it, we have discussed this with many
Institutes because obesity is the cause or one of the factors
in so much illness. How high a priority is it at the Center?
I have known several people who have been taking chromium
picolinate. Where is it in terms of priorities?
Dr. Straus. The Center is one year old and we are just
mounting our portfolio, but it is already on our list of the
top ten new priorities for new investment, depending upon our
budgetary options for 2001. This is a priority that I have
discussed with NIDDK.
Mrs. Lowey. Well, I thank you, and I hear the buzzer. I
look forward to working with you because, as our distinguished
Chairman has said, these are, substances that millions of
people are using. The health food stores are selling them, and
I think it is an absolute priority and an urgency for the
Institute to really do more research.
Dr. Straus. Thank you. I agree with you. It is the public
health opportunity that exists to address complementary and
alternative medicine that really convinced me to take this
position. I think this is a truly important issue for the
American public. Because a substance is natural does not mean
that it is ineffective or effective, and it certainly does not
mean that it is safe. We need to address both of those at the
same time.
Thank you, Mrs. Lowey.
Mrs. Lowey. Thank you.
And thank you, Mr. Chairman.
Mr. Porter. Thank you, Ms. Lowey.
Mr. Jackson?
ESTABLISHMENT OF NCCAM
Mr. Jackson. Thank you, Mr. Chairman, and thank you, Dr.
Straus. I want to welcome you and thank you for taking the time
to talk about NCCAM's budget.
Dr. Straus, when was the Office of Alternative Medicine
elevated to the National Center for Complementary and
Alternative Medicine?
Dr. Straus. The language, I believe, was in 1998, and it's
established by the Secretary February 1999.
[Clerk's note.--The Language was part of the FY 1999
Omnibus Appropriation and its establishment was approved by the
Secretary in February 1999.]
Mr. Jackson. How many people were using alternative
medicine at the time OAM was elevated to a Center?
Dr. Straus. The estimate that year was upwards of 40
percent of Americans.
Mr. Jackson. That is very interesting because many of the
disparities that I have been talking about over the course of
the line of my questioning during these hearings actually
predate the elevation of your department to a center, but I see
that this approach to alternative medicine has at least been
elevated to the level of a center as a priority. I am wondering
what was the need to elevate the OAM?
Dr. Straus. I was not in the OAM at that time and cannot
speak to all the issues. I am sure that Dr. Kirschstein could
give you that history better than I. As I reflect on it, I know
that it was in response to the true public health significance
of the opportunities and challenges brought by complementary
and alternative medical practices today.
Mr. Jackson. Public health significance?
Dr. Straus. Yes.
ROLE OF FDA
Mr. Jackson. One of the reasons I have been trying to
elevate the Office of Research in Minority Health to the level
of center is because I have always, at least from my
perspective, assumed that addressing some of these disparities
are of significance as well.
I assume that before alternative medicines can be used that
they are researched and approved by the FDA?
Dr. Straus. No.
Mr. Jackson. They are not?
Dr. Straus. These are modalities that are in the market
place and available today. You could walk into the supermarket
and pull off the shelf and purchase any of the hundreds of
different supplements and botanical products.
DRUG INTERACTIONS
Mr. Jackson. I would imagine then that part of the
responsibility and mandate of your center is to make sure that
the coordination of various types of alternative medicines do
not create complicated problems for individuals who might be
taking, let us say, ginko biloba on the one hand, but drinking
Earl Gray tea on the other hand, that that such combination
might be troubling for someone?
Dr. Straus. Exactly right. If we are to presume that the
chemical and biological modalities, as opposed to magnets and
other things, are truly active then they can be active only
because they can affect the body's inherent physiology. This
would mean that you are drawing upon its effects for beneficial
purposes; there may be expected or unexpected and, in some
cases, serious untoward effects as well. As I illustrated in my
prior comments, our studies of St. John's Wort provide just one
such example. We are funding investigations through botanical
centers, together with the Office of Dietary Supplements, to
address the pharmacology of these substances, and drug
interactions.
As I pointed out in the display panel, there was a 10-fold
reduction in blood level of an important HIV drug, simply by
adding St. John's Wort into the drug cocktail, at a level which
is now at risk of being ineffective in promoting treatment
effectiveness.
Your question is a very important one for our research
agenda.
DEMOGRAPHICS OF CAM USE
Mr. Jackson. I have just maybe two more questions if I can
squeeze them in before the bell goes off.
You said an estimated 40 percent of Americans were using
alternative medicines. I wonder if there is any data to suggest
that let us say 45 million Americans who do not have any form
of health care are using alternative medicines because they
cannot afford prescription drugs, or the vast majority of those
Americans who have no form of health coverage, whatsoever, that
they are using alternative medicines as a way around a system
that they fundamentally cannot afford?
Dr. Straus. That is an important question. Although there
are surveys reported, I believe that we can do better in
surveying the American people, and I have been meeting with
staff from the Centers for Disease Control to talk about how we
can do a better analysis of the demographics of CAM use across
the country regionally, in terms of ethnic and racial groups,
by gender, and by socioeconomic and educational status.
The existing data suggest that there is a greater use in
wealthier Americans, because these treatments are not
reimbursable and they are paid for out-of-pocket. Americans
spent over $27 billion out-of-pocket in 1996 to 1997 for these
therapies.
But individuals who do not have the same disposable income
do turn to complementary and alternative therapies, because in
many instances they have grown up with them. Our studies have
the capacity to address health disparities in a unique way
through our center. African Americans in the rural South,
Hispanic Americans in the Southwest, Native Americans in the
Southwest, the Inuits and the Hawaiians, as well as immigrants
from other countries, brought with them or sustain from their
own cultures the belief in their own approaches to health care.
In some instances, these practices do replace mainstream,
conventional therapeutics.
TOTAL HEALTH CARE COSTS ASSOCIATED WITH CAM
Mr. Porter. Thank you, Mr. Jackson.
Dr. Straus, let us talk about dollars. Are there estimates
as to the total health care costs including all forms, all
therapies and then is there an estimate of those that are under
your purview? In other words, what proportion of the total
health care costs would you be looking at?
Dr. Straus. Mr. Chairman, I do not know the answer to that
question because a lot of that data has not been accumulated. I
do know the estimates of out-of-pocket expenditures, as I have
indicated, and I also know that health maintenance
organizations and insurers are increasingly reimbursing the
costs of cam treatments, particularly for acupuncture and
chiropractic care. Over 70 percent of HMOs are offering some of
these practices, not necessarily because they are proven.
Although there are proven benefits of acupuncture for chronic
pain, for example, some are offered because the market is
demanding it.
Mr. Porter. I guess that there is no way to really draw the
line between what is traditional because acupuncture, for
example in my judgment, has crossed the line into traditional
now.
Dr. Straus. Yes. That is absolutely correct.
Mr. Porter. It is accepted.
Dr. Straus. Acupuncturists are licensed in many states and
it is practiced in all 50 States. Many individuals are turning
to acupuncture for relief of chronic pain when they cannot
obtain relief elsewhere.
FUNDING GOOD SCIENCE
Mr. Porter. If we look at the office that preceded you and
we looked at their budget, and then we looked at where we are
today and where we are likely to go, in fiscal year 1998 there
was about $20,000,000 put in this account and none of that
could be used directly by the office to fund research. It had
to go through an institute----
Dr. Straus. That is correct.
Mr. Porter [continuing]. And get them to approve it. We
raised it to $50,000,000--I am using round figures--in fiscal
year 1999; $68,000,000 in this fiscal year and while the
President is indicating $72,000,000, we hope to go considerably
higher than that. And, so, your office, now-center, is going to
have perhaps a 400 percent increase in four years or 100
percent average increase per year.
Now, there is not a research community out there that has
been doing this kind of research, at least on these particular
therapies or modalities. Are you able to spend that kind of
increase wisely? In other words, has science lined up to do
this kind of research in the last year or two in a way where
you know you are funding good research, using the money wisely?
Dr. Straus. That is a very important question. And let me
say that I am convinced that we are funding good science, that
we are getting increasing numbers of applications and they are
increasingly excellent. In fact, our ability to fund
applications, percentage-wise, will fall over the coming year
or two because of the rate of new applications.
Part of the reason for the growth in applications and their
quality has to do with the fact that there is, a latent need
that had not been addressed previously to study these various
modalities. Many of these modalities have been, can be, and are
now being studied by some of the country's best investigators.
So, for example, the St. John's wort study is a multi-
center trial that is being conducted by some of the best mental
health scientists, psychiatric experts and investigators of
antidepression, of antidepressant drugs. Our Ginko Biloba trial
is being conducted together with the National Institute on
Aging by the best individuals who understand the process of
dementia in aging Americans. So, a lot of our early research
advances require nothing more than seducing good, smart people
to turn their focus where there is a great new opportunity and,
of course, money speaks.
These investigators recognize the potential of cam. Not
only is the scientific community embracing what we are doing,
the patient advocate community seems to be thrilled as well
with what is happening. My colleagues in the other NIH
institutes and centers have come to the plate, as well. I have
personally met with all the institute and center directors as
well as representatives of all the other health agencies in a
trans-agency committee that I chair and they are eager to
collaborate. For example, this afternoon I am addressing a
planning committee for the FY 2002 portfolio for the Aging
Institute. I will be addressing the advisory council of the
Arthritis Institute.
We are joining together and funding good research. While
your generous funding has allowed a rapid growth in NCCAM's
budget, at the same time the total spending over the past three
years by the other institutes has not diminished; it has
increased by an additional 181 percent. So, we could address
the increase. Now, if you gave us a billion dollars tomorrow we
could not address wisely. We have to do this in a tiered,
thoughtful way.
Mr. Porter. Yes, sir. Well, that is exactly what I wanted
to know. Mrs. Lowey, any further questions?
Mrs. Lowey. I do not think so, Mr. Chairman.
Mr. Porter. Mr. Jackson
Mr. Jackson. Thank you, Mr. Chairman.
I just have a brief statement. Dr. Straus has really
motivated me today.
Mr. Porter. Good.
Mr. Jackson. Because of the rapid growth of his field of
expertise and the rapid growth of funding across NIH and
certainly the considerations that this Committee are going to
make with respect to his budget but particularly his ability to
offer grants in areas that further explore and study this has
just motivated me for a number of reasons, Mr. Chairman, and I
want to congratulate Dr. Straus for what I am sure will be an
extremely beneficial effort on behalf of all the American
people in the Office of Alternative Medicine, now, elevated to
National Center for Complementary and Alternative Medicine. I
hope to elevate at some point in time if we see the wisdom in
this, the same type of coordination across centers for minority
health and minority research so that whomever that director
might be one day they might be able to come and say that I got
a very busy schedule this afternoon because I have to go to the
Cancer Institute and I have to go to the Diabetes Institute and
I am coordinating across the entire Center these efforts and we
are going to be issuing some grants to study this in this area.
And I want to make just one other brief argument. And that
is the cultural argument that you made that some of these roots
in alternative medicines come from Native American culture,
they come from Africa, they come from a lot of rural cultures
that have had to rely upon not the sophistication that NIH has
offered but what is available to them as alternatives to pain
and disease and illness. It would just seem so logical to me
that these alternative medicines which have deep roots in these
various cultures, that much of the research since these have
been very long-standing traditions in many of these cultures
that the experts in this area would, at some point in time,
begin to reflect those cultures for which have been using these
various remedies for a number of years.
And, so, I thank you, Dr. Straus and thank you, Mr.
Chairman, for the time.
Dr. Straus. Thank you, Mr. Jackson.
Mr. Porter. Thank you, Mr. Jackson.
Dr. Straus, what you are doing is to us very, very
important. The buying habits of people in a free society ought
to direct us to have our energies applied to making sure that
their money is wisely spent and they are safe from materials or
therapies that could be dangerous to them. And I think the
amount, the field that you have to cover is absolutely huge. We
are anxious to give you the resources you need to do as much of
that as quickly as possible but with good science.
I will watch, perhaps a little bit outside the institution,
but watch with great interest as your mission grows and is
fulfilled and see the kinds of good scientific work that can be
brought to bear on understanding what does work and what does
not.
I think it is very, very important. We am glad you are
there. We wish you well.
Dr. Straus. Thank you, Mr. Chairman, and I look forward to
continuing to learn your perspective for coming years.
Mr. Porter. Thank you, Dr. Straus.
The Subcommittee will stand in recess until 2 p.m.
