Dataset from Hemophilia Growth and Development Study

A multicenter study of hemophilia and its complications, HGDS was established in 1988. Data were prospectively collected in 14 US hemophilia treatment centers through 1996/97. The HGDS investigated the effects of hemophilia and HIV on physical growth and maturation; immunological, neurological, and neuropsychological functioning; and the pathophysiology of HIV and hepatitis C. Research using the clinical data and stored samples continues and includes the genetic research that paved the way for development of the protease inhibitors currently used to treat HIV; studies that provided clues to viral characteristics of HIV and hepatitis B and C; research to identify genetic factors associated with the development of inhibitory antibodies to factor VIII; the relationship of inhibitors to cognitive development and academic achievement; studies of viral factors and how they relate to progression of HIV and hepatitis C; and research on the parenteral transmission of human viruses. Biospecimens are available.
