title: Low risk of transmission of the human immunodeficiency virus by a solvent-detergent-treated commercial factor VIII concentrate.
abstract: A study evaluating the risk of a commercial factor VIII (FVIII) concentrate's transmitting the human immunodeficiency virus (HIV) was carried out on hemophiliacs, by using multiple serological markers and the polymerase chain reaction (PCR). Twenty-nine hemophiliacs, negative for HIV antibodies, were treated for 18 months with a concentrate that had been inactivated by solvent-detergent. HIV-1 antibodies and antigen were assayed during the follow-up period. At the end of the study, all patients were also tested by the HIV 1 + 2 combined antibody assay; Western blot (WB) antibody analysis; and in eight cases, by an HIV-1 PCR technique. Patients received a yearly median FVIII dose of 35,330 IU (range 3,300-306,000); the median number of lots given to each patient was 6 (1-45). During the follow-up period and at the end of the study, HIV-1 antibodies and antigen were not detected in any of the subjects. The HIV 1 + 2 combined assay and WB analysis carried out only at the end of the study were negative. HIV-1 PCR was negative in all the tested patients. This study has shown that this solvent-detergent-treated FVIII concentrate did not transmit HIV.
