[Transmission of the human immunodeficiency virus by a dry heat-treated Factor VIII concentrate?].

Short presentation of the common procedures to avoid transmission of human-immunodeficiency-virus (HIV) by hemoderivates especially clotting-factor-preparations. The stepwise seroconversion (ELISA, IFT, Western-blot) of HIV is shown in a 7 5/12 ys old boy with hemophilia A after administration of a dry-heated factor VIII-preparation. Seven similar observations were reported in the literature. On the other hand HIV-seroconversion could not be observed during treatment with wet-heated factor VIII-preparations. In consequence only wet-heated factor VIII-preparations and factor IX-preparations respectively should be administered to hemophiliacs without HIV-antibodies. By this precaution transmission of non-A, non-B-hepatitis may be avoided simultaneously.
