Hemophilic patients seronegative for HIV treated exclusively with heated concentrates at first showed no seroconversion (1-3). Later, two hemophiliacs seroconverted after having been treated with the same factor VIII concentrate that had been heated in the lyophilized state (freeze-dried) at 60 °C for 30 hours (4, 5). This relatively low heating temperature and short time period might be insufficient to inactivate HIV. During our follow-up of 63 hemophiliacs who were seronegative before the exclusive usage of heated concentrates was initiated, three became persistently...References1.
