Abstract
A retrospective investigation was carried out to evaluate the influence of HLA (A, B) matching, blood transfusions, and preexistence of lymphocytotoxic antibodies on the outcome of the cadaver kidney graft: only non-NIH standard antibodies were considered, since patients with NIH standard antibodies do not undergo transplantation in the programme of Milano. It was found that (1) about one-half the patients with transplants had antibodies in their pretransplant serum. The preexistence of antibodies directed against B lymphocytes had an unfavourable effect on the graft survival; (2) the graft did particularly well in the nonimmunized patients who had been previously transfused; the graft survival was about 80% at 3 years in these patients; and (3) the HLA (A, B) match influenced the graft survival only in patients with antibodies.
