Cytotoxic T lymphocyte changes after HLA-DR match and HLA-DR mismatch blood transfusions.

In the present study, we analyzed transfusion-induced cytolytic T lymphocyte (CTL) changes in patients who received either a one-HLA-DR-match or a zero-HLA-DR-match pretransplant blood transfusion. Twenty-four nonimmunized naive patients awaiting kidney transplantation received one planned, HLA-typed blood transfusion. The frequencies of CTL precursors (CTLp) directed against blood donor cells and controls were evaluated before and sequentially at days 7, 28, and 60 after transfusion.
