    Abstract:
    A positive effect on survival of renal grafts of pretransplant blood transfusions have been reported from several centers. The aim of this study was to study if the described graft-protecting effect of blood transfusion was present in the Gothenburg material of transplanted patients, and if this effect could be achieved by deliberately transfusing previously non-transfused patients with two units of leukocyte-reduced blood. The effect on graft survival (GS) of the number and timing of transfusions to recipients, transfusions to the cadaveric donors, HLA-A, B matching, lymphocytotoxic antibodies and pretransplant hemodialysis was also studied. The study includes 844 recipients of primary renal grafts from living related and cadaveric donors (LRD, CD) and 70 patients waiting for transplantation. In the retrospective part of the study the GS of previously transfused and non-transfused non-transfused patients was compared. In the prospective part of the study a protocol with two deliberate transfusions (DT) to previously non-transfused patients was introduced. The GS of the DT group was compared to that for patients transfused for strictly medical reasons (MT) and non-transfused patients (NT). Survival of patients and grafts was calculated according to the life table method. In the retrospective part of study one year GS in LRD transplantation was 86.6% for transfused and 38.4% for non-transfused patients (P less than 0.01). In the first period one year GS in CD transplantation was 62.1% for transfused and 35.1% for non-transfused patients (P less than 0.01). The corresponding figures in the second period were 68.1% and 39.5%, respectively (P less than 0.001). In transfused recipients receiving kidneys from transfused and non-transfused cadaveric donors, the GS was 76.3% and 55.4%, respectively (P less than 0.05). In the prospective part of study the one year GS after LRD transplantation was 85.0% in both the DT and MT groups. In CD transplantation the one year GS was 73.4% and 75.7% of the DT and MT groups, respectively. The GS of each of these two groups was significantly better than that of 20.8% for the NT group (P less than 0.01). Lymphocytotoxic antibodies were detected in 5.0% of the DT group and 23.0% of the MT group (P less than 0.001). Foreign HLA-B series antigens had a negative influence on GS in the first period of the retrospective CD study. Later, no influence on GS was noted of HLA-A, B matching. Hemodialysis prior to transplantation did not influence GS.(ABSTRACT TRUNCATED AT 400 WORDS)
