Systemic lupus erythematosus (lupus; SLE), Systemic Sclerosis (scleroderma; SSc) and Systemic Vasculitis (SV) are relatively rare rheumatic diseases that disproportionately impact the African American community, and particularly African American women. The causes of lupus, scleroderma and vasculitis are unknown, but thought to include both genetic and environmental factors. We are enrolling lupus, scleroderma, and vasculitis patients, and healthy control subjects. This is not a drug study. The purpose of this study is to better understand the factors that predispose people to develop lupus, scleroderma, and vasculitis. Information about medical, social and family history, medications, physical exam findings, and laboratory tests will be collected for analysis. This study will involve approximately 1360 volunteers.
