Absence of Anti-Human Immunodeficiency Virus Types 1 and 2 Seroconversion after the Treatment of Hemophilia A or von Willebrand's Disease with Pasteurized Factor VIII Concentrate

Abstract
Patients with hemophilia A or von Willebrand's disease who are treated with concentrated preparations of human factor VIII made from unscreened pooled plasma are at substantial risk of contracting human immunodeficiency virus (HIV) infection. The purpose of this study was to investigate whether by treating such patients with a pasteurized factor VIM concentrate that had been heated in aqueous solution at 60°C for 10 hours, HIV infection could be avoided.
