title: Graft survival with high levels of cytotoxic antibodies.
abstract: In this study, pretransplant transfusions significantly improved the survival of first cadaver kidney transplants. Large numbers of transfusions had the same influence on graft survival as small number of transfusions. Graft survival was not influenced by pretransplant antibody levels, and the beneficial effect of transfusions was also independent of highest pretransplant antibody levels. The positive relationship between transfusions and cytotoxic antibodies was shown to be highly significant. B-warm and T-warm antibodies were both increased by transfusions and tended to occur together. B-cold antibodies occurred independent of transfusions, B-warm and T-warm antibodies. The results of this study suggest, but do not confirm, that B-cold antibodies benefit graft survival, while T-warm antibodies adversely influence graft survival. Transfusions and B-cold antibodies appear to influence graft survival by different mechanisms.
