NIH Funds Scleroderma Research
The division of rheumatology of the department of medicine has
been awarded a four-year grant totalling $911,935 to study biochemical and
vascular alterations in scleroderma, a progressively crippling and often
fatal disease attacking the skin and internal organs. Sergio A. Jimenez,
MD, the Dorrance H. Hamilton Professor of Medicine, director of rheumatology,
and professor of biochemistry and molecular biology; and Elena Hitraya,
MD, PhD, research assistant professor of rheumatology, are co-investigators
of the project funded by the National Institutes of Arthritis and Muscular
Skeletal Diseases of the National Institutes of Health.
Drs. Jimenez and Hitraya are examining the mechanism responsible for the
exaggerated production of collagen which leads to the clinical manifestations
of scleroderma. The cause of scleroderma is unknown, but by gaining a better
understanding of the disease process, the researchers hope to discover new
and improved therapeutic remedies. "If we can prevent the development
of fibrosis (thickening of the skin caused by uncontrolled accumulation
of fibrous tissue), we can control the clinical symptoms that can lead to
death. We'll be using the most advanced methods of molecular biology and
genetics," says Dr. Jimenez, who has been studying scleroderma for
nearly 30 years.
Jefferson boasts one of the foremost research and clinical centers for scleroderma
in the world. The grant from NIH is one of only a handful awarded for scleroderma
research over the last decade, according to Dr. Jimenez. About 500,000 Americans
suffer from scleroderma, the majority being women between the ages of 25
and 45.
