The hepatitis viruses and HIV threaten the worldwide blood supply
Thousands of plasma donations were combined as starting material for one batch of plasma-derived factor VIII or factor IX concentrate, and by the early 1980s, human blood, plasma, and plasma-derived products were discovered to be transmitting potentially deadly blood-borne viruses, including hepatitis viruses and HIV.
Manufacturers of plasma derived clotting factor concentrates attempted to kill these viruses with dry heat, solvent-detergent treatment, and pasteurization, with varying degrees of success. By 1985, most patients with hemophilia in the U.S. had been switched to heat-treated concentrates, but many had already been infected with HIV and a large percentage of them succumbed to it. Great concern about the safety of plasma derived products continued in the hemophilia community.
