title: [Prophylactic replacement therapy in hemophilia. A case report (author's transl)].
abstract: In a six year old boy with severe hemophilia prophylactic substitution of factor VIII was started in 1973 in order to prevent early invalidity due to series of bleeding in the right anklejoint. A substitution of factor VIII over 8 months with 21 resp. 30 U/kg body-weight did not lead to a significant improvement. But since the factor VIII in a dosage of 18 U/kg body-weight is given three times a week no bleeding occurred during the treatment time of 14 months and also the ability to walk improved to an excellent degree.--So far no signs of hepatitis or an factor-VIII-antibody could be detected.--Some results from the prophylactic treatment of severe hemophilia and Christmas disease are cited from the literature.
