Beneficial effects of donor-specific transfusion on renal allograft outcome.

Introduction: Donor-specific transfusion (DST) is claimed to improve graft survival in living kidney transplantation. The aim of this study was to determine the influence of DST on the incidence of acute rejection (AR), graft function and survival in the early and late post-transplantation period in transfusion-naïve patients.
Methods: Three patient groups were compared: group 1 received DST (n = 18), group 2 patients received no transfusion prior to surgery (n = 13) and group 3 consisted of 132 randomly transfused patients. The DST protocol consisted of infusion of fresh whole donor blood (3 × 150 mL) at two-wk intervals accompanied by three d of azathioprine. All patients were grafted within one month after the third DST. Triple drug immunosuppression based on cyclosporine A was given to all patients.
Results: DST and polytransfused patients experienced significantly less AR compared with group 2 patients. Two-yr graft function was significantly better in patients in groups 1 and 3 compared with group 2. Although similar eight-yr patient and graft survival was found in all the groups, delayed graft function patients had the longest graft half-life.
Conclusion: DST imposes a significant beneficial effect on the incidence of AR, DGF and graft function during the first post-transplantation year in transfusion-naïve patients receiving standard immunosuppression therapy.
