title: [Effect of factor VIII, factor IX and immunoglobulin preparations on mitogen-induced lymphocyte proliferation].
abstract: The influence of therapeutic dosages of factor VIII, factor IX and immunoglobulin preparations on the proliferative capacity of mitogen-activated lymphocytes from patients with hemophilia or idiopathic thrombocytopenia was investigated. Addition of protein preparations in vitro led to inhibition of lymphocyte proliferation, predominantly with the mitogen staphylococcus enterotoxin B. After intravenous application of proteins also stimulatory effects were seen. Since long-term treatment with protein preparations might impair immune functions, their application should be considered carefully.
