innovative therapies, that were unimaginable just a few years ago.

Ongoing

NIAMS epidemiological investigation of Native Americans in Alaska and Siberian

Eskimos--populations that have a high prevalence of spondylitis--pronises to

shed light on the roles of genetic factors and environmental triggers, such as

bacterial infections.

Systemic lupus erythematosus (lupus) is an immune -mediated inflammatory

disease that afflicts numerous Americans, largely young women, especially black

women of child bearing age.

The disease affects the skin, joints, kidneys,

brain, and other organs.

Recently, a new antibody was identified that is

clearly associated with psychiatric disorders due to lupus; this antibody will

make better diagnosis possible.

The Institute has set up a task force to study lupus in high-risk

populations.

With advice from the task force, NIAMS is developing Instructive

kits that will help health care providers and community organizations conduct

health promotion programs targeted to young black women.

The Institute also

plans to sponsor an international workshop on systemic lupus erythenatosus to

assess current knowledge and develop directions for future research.

Scleroderma is a serious disorder of connective tissue and the fine blood

vessels.

Besides damaging the skin, muscles, and joints, the disease may also

affect internal organs, such as the kidneys, heart, and lungs, making it life

threatening in some people.

Women are affected three times more often than

men.

The first symptom of scleroderma is usually Raynaud's phenomenon, wherein

blood vessels in the fingers narrow as the result of vasospasm, causing the

There is also pathologic evidence of vascular

disease seen under the microscope. Accordingly, there is keen interest in exploring vascular abnormalities that may contribute to the etiology of the

disease.

NIAMS will issue a program announcement to stimulate more research on

causal mechanisms in scleroderma.

Over 100 different conditions are included among the heritable connective

tissue disorders, all of which stem from abnormalities of connective tissue,

the scaffolding that girds bone, skin, blood vessels, and the protective

coverings of internal organs. Although the disorders are uncommon, they are

tremendously disabling.

In April 1990, NIAMS cosponsored a multidisciplinary

scientific workshop on heritable connective tissue disorders.

Workshop

participants made it clear that sophisticated research methods are enabling

scientists to unravel the complex biology of connective tissue and to uncover

the several defects that cause the disorders.

The Institute is encouraging

additional research in this area, and is exploring the possibility of a patient

registry to facilitate progress against these diseases.

Reducing the risk of sports injury is important to millions of Americans

who participate in exercise programs and athletics.

The Institute's mission

Includes responsibility for research on exercise physiology and sports

medicine,

Basic facts about how muscles function at the molecular level are

now being discovered.

Recent research has revealed a mechanism by which a

serious knee injury can destroy a joint.

In April 1991, the Institute, in

concert with the National Advisory Board, will hold a workshop on scholastic

sports Injuries to monitor the causes of athletic injuries and identify ways to

prevent them.

We are continuing to make progress in research on the numerous skin

diseases that affect so many Americans.

In epidermolysis bullosa, a

devastating inherited blistering disease that affects the skin and mucous

membranes, researchers have found that the anchoring fibrils--which link the

outer layer of the skin to the inner layer--are conspicuously absent or

altered.

Recent investigations have also shown that type VII collagen, the

major structural protein of anchoring fibrils, can be broken down by both

collagenase and gelatinase.

Other research, utilizing patients assembled by

the National Epidermolysis Bullosa Registry, suggests that abnormal synthesis

of type VII collagen be responsible for the reduced number of anchoring

fibrils.

Alopecia areata is a disease of the hair follicle that results in patchy

or total loss of hair.

The psychological impact of the disease can be

debilitating, especially in young people.

In October 1990, NIAMS and the

National Alopecia Areata Foundation sponsored a 2-day research workshop on the

disease.

Experts in a wide variety of areas were convened for an open exchange

of information on clinical and histopathologic features of alopecia areata,

factors controlling hair growth, autoimmune aspects of the disease,

pharmacologic interventions, and animal models.

A new anatomic site that

controls hair growth has been discovered, and the ability to grow hair in a

test tube has been achieved.

These findings open new avenues of research that

will be pursued.

Psoriasis is a common chronic skin disease characterized by scaling and

redness produced by skin cells that divide rapidly.

For many years, psoriasis

was treated with preparations of tars and chemotherapeutic agents, such as

me thotrexate. Recently, clinical studies established the efficacy of

cyclosporine A, an immuno-suppressive drug in the treatment of psoriasis.

In

turn, this has led investigators to explore the role of immune - pediated factors

in causing the disease and to search for alternative drugs that cause fewer

side effects than does cyclosporine A.

The NIAMS is encouraging further

exploration of molecular, immunologic, and pharmacologic aspects of psoriasis.

Significant strides have been made in the Institute's Intramural Program.

This past year two new laboratories were established to expand the scope of

research: the Laboratory of Skin Biology and the Laboratory of Structural

Biology Research,

Fundamental studies of proteins responsible for naturation

of the epidermis, the skin's outer layer, are the focus of research in the

Laboratory of Skin Biology. In the Laboratory of Structural Biology Research, new sophisticated Instrumentation is facilitating analysis of extremely small

structures, including membrane-associated components of the AIDS virus.

In the area of orthopaedic research, Intramural scientists have identified

the various phases through which an injured bone must pass to heal properly.

They have detected the presence of a specific natural protein, transforming

growth factor-beta (TGF-beta), between and around the ends of fractured bone;

and determined that TGF-beta not only initiates a repair response,

but also

controls the rate of fracture healing.

Another ground-breaking accomplishment achieved by intramural scientists

was the development of an animal model for eosinophilia-myalgia syndrome (EMS),

a new epidemic inflammatory disease associated with ingestion of contaminated

L-tryptophan. Symptoms range from those of the flu, to severe rashes and

permanent nerve and muscle damage.

The new animal model provides the first

direct, experimental evidence linking EMS to contaminated batches of the

dietary supplement L-tr

tophan.

Collaborations between NIAMS and the Department of Defense continue in

studies of skin manifestations in human immunodeficiency virus (HIV)- Infected

individuals. Establishment of a new interagency agreement will significantly increase the rate of accrual of HIV-positive subjects into the studies to give

us an earlier estimate of the prevalence of skin disorders and accelerate the

pace of this research.

Mr. Chairman, the budget request for NIAMS for fiscal year 1992 is

$204,797.000.

I will be pleased to answer any questions you may have.

I'm sorry.

NATIONAL PLAN Senator HARKIN. Thank you very much, Dr. Shulman. How soon are we going to have this national plan, did you say? Dr. SHULMAN. It is going to be before the next hearings. Senator HARKIN. Good.

Well, I had a question on osteoporosis, but you covered that. And lyme disease you covered that quite well. And lupus.

Just a moment. (Pause.) My apologies. I have to run over and cast another vote right now. My apologies.

(A brief recess was taken.)

QUESTIONS SUBMITTED BY THE SUBCOMMITTEE Senator HARKIN. Thank you very much. There will be some additional questions which will be submitted for your response in the record.

[The following questions were not asked at the hearing, but were submitted to the Institute for response subsequent to the hearing:)
