[Prolonged renal graft survival induced by blood transfusion (author's transl)].

All renal allotransplants performed at the Cantonal Hospital, Zurich, in 1975 and 1976 were analysed with respect to pre-transplant blood transfusions, excluding secondary transplants, patients on dialysis outside of Switzerland, combined renal and pancreatic transplants, and women with previous pregnancies but without transfusions. Among 72 patients left for analysis there were 16 who had never received any pre-transplant blood transfusion. Their graft survival was much worse (one-year graft survival 36%) than that in patients with previous transfusions (one-year graft survival 70--80%). Patients without previous blood transfusion should, therefore, no longer be admitted for renal transplantation.
