Abstract
One hundred ninety-one consecutive living related transplants performed from 1969 to the end of 1978 have been analyzed for the effect of pretransplant blood transfusions. Superior graft survival was observed in transfused patients transplanted with a one HLA haplotype-disparate kidney, whereas no effect of blood transfusions could be observed on the survival of HLA-identical transplants. The frequency of first rejection episodes was significantly reduced in transfused compared to nontransfused one haplotype-mismatched transplants, while no influence of blood transfusions was seen in patients with HLA-identical transplants. The survival of patients was, however, not influenced by previous transfusions. Pretransplant hemodialysis improved graft survival and patient survival; the difference was, however, only significant at 2 years in the one haplotype-mismatched group. When analyzed separately, both blood transfusions and hemodialysis had a beneficial effect on graft survival in one haplotype-mismatched transplants.
