Abstract
There is uncertainty about the role of blood transfusion of potential kidney graft recipients. In this study baboons were transfused under conditions mimicking the clinical situation and then callenged with kidney allografts. Eleven baboons were transfused 10 times with blood from different donors. Lymphocytotoxic antibodies induced against the separated B and T cells of a panel of 12 normal baboons were as follows: B-T- 30%; B+T- 3%; B-T+ 1% and B+T+ 66%. Kidney transplantations were done from donors against which the recipients had negative B-T- cross-matches. Median allograft survival time (MST) of 12 days in this group, which was immunosuppressed with azathioprine and prednisolone, was not prolonged when compared with non-transfused, immunosuppressed animals (MST 12 days). A second group of 14 animals was screened for cytotoxins after each transfusion against a panel of five to six normal baboons. The antibody profile of 80 combinations tested after three transfusions was as follows: B-T- 65%; B+T- 16%, B-T+ 0% and B+T+ 19%. Transplantation was with donors against which the transfused recipient had formed B+T- antibodies. Kidney allograft survival was again not prolonged (MST 13 days) but the mean serum creatinine level 8 days after transplantation was significantly lower than that observed in the first group.
