The effect of mismatching and sharing of HLA-A, -B, and -DR antigens on kidney graft survival in Eurotransplant 1982 to 1988.

1. Cyclosporine significantly improved kidney graft survival by 10-15%. 2. Matching for HLA-DR, HLA-B + DR and HLA-A + B + DR improved kidney graft survival significantly in non-CsA-treated patients. 3. Matching for the HLA-A, -B, and -DR loci, apart and in combination, significantly improved kidney graft survival in CsA-treated patients. 4. The best kidney graft survival was observed in HLA-A + B + DR identical combinations treated with CsA (76% at 5 yrs).
