[Anti-HBS, anti-CMV, and anti-HIV antibodies and HBS antigen in patients with hemophilia, malignant lymphomas, leukemias and multiple myeloma].

In 21 patients with haemophilia, 10 with acute leukaemia, 12 with malignant lymphomas, and 12 with multiple myeloma in whom the risk of viral infection is increased the following antibodies were determined: anti- CMV, anti-HIV, anti-HBs, and HBs antigen by ELISA test. Anti-CMV were found mainly in acute leukaemia (90%), in haemophilia (71.4%), in malignant lymphoma (41.7%) and multiple myeloma (33.3%). In 19% of cases of haemophilia anti-HIV antibodies were present. In other groups these antibodies were not found. In acute leukaemias mostly anti-HBs antibodies were present. The group of haemophiliacs is particularly exposed to infection by these viruses which is connected unquestionably to blood transfusions.
