In other recent research, a dissimilarity in tissue type between

mother and fetus has been found in many women with rheumatoid arthritis who

improve during pregnancy.

This finding suggests that the nismatch induces an

immunologic reaction that suppresses the arthritis.

Lyme disease, which has both arthritis and skin disease among its major

manifestations, has become a national problem.

It is now the most common

insect-borne disease in the Nation, and its distribution is worldwide.


is giving high priority to both research and outreach programs for Lyme


The Institute has recently funded several new basic research grants

to increase understanding of how the infectious agent causes the disease, with

the hopes of improving diagnosis and treatment, and providing the foundation

for development of an effective vaccine.

NIAMS is also supporting a clinical

trial to determine if antibiotics can prevent Lyme disease from emerging in

people who have been bitten by the deer tick. Programs to better inform both

the public and health professionals about the dangers and prevention of Lyme

disease are under way.

A data base on educational materials was recently

completed; and in early March 1991, a workshop on Lyme disease will be held

with panels of experts to develop up-to-date vital information for physicians

on both the diagnosis and treatment of Lyme disease.

One of the most exciting breakthroughs this year was the identification of

a gene that causes a form of osteoarthritis, the most common form of arthritis,

a disease in which the cartilage that covers and cushions the joints breaks


NIAMS-supported investigators at two different grantee institutions,

working together, isolated and characterized a faulty gene for collagen II, the

main structural protein that strengthens cartilage.

Another exciting breakthrough in arthritis this year was the successful

induction, by transgenic transfer, into inbred rats of both the human gene

(HLA-B27) for spinal arthritis and the entire clinical spectrum of the group of

diseases (spondyloarthropathies) associated with spinal arthritis.

HLA-B27 is

found in over 90 percent of patients with spinal arthritis, and in only 8

percent of the general population. These diseases associated with spinal

arthritis comprise the most common forms of arthritis in young men.


striking mimicry between the disease manifestations found in this animal model

and those found in humans opens avenues for research, including the testing of

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


NIAMS epidemiological investigation of Native Americans in Alaska and Siberian

Eskimos--populations that have a high prevalence of spondylitis--promises 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


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 erythematosus to

assess current knowledge and develop directions for future research,

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


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


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

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

hands to become pale and cold.

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



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.


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


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


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


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


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 methotrexate. Recently, clinical studies established the efficacy of

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


turn, this has led investigators to explore the role of immune-mediated 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 Progran.

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 maturation

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


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-tryptophan.

Collaborations between NIAMS and the Department of Defense continue in

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


Establishment of a new Interagency agreement will significantly

Increase the rate of accrual of HIV-positive subject

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.
