Effect of transfusion of donor on allograft survival
It has been reported by two European transplant centers that blood transfusion of cadaver donors with third-party blood prior to nephrectomy increases renal allograft survival rates by approximately 30% at 1 year. A retrospective analysis in our center was performed on 293 kidney recipients, 110 of whom received kidneys from untransfused donors. Actuarial analyses revealed no significant differences in graft survival rates between all nontransfused donor kidneys and all transfused donor kidneys. Considering only first transplant recipients, there was no difference in graft survival rates between nontransfused donor kidneys and transfused donor kidneys. In addition, when only preoperatively transfused recipients receiving first transplants were examined, there was no difference in graft survival rates between nontransfused donor kidneys and transfused donor kidneys. Animal studies were performed with (Lewis x Brown Norway)F1 (LBNF1) hybrid rat hearts transplanted heterotopically to the abdomens of Lewis rat recipients. Six LBNF1 heart grafts had a mean survival time of 8.0 +/- 1.1 days. Five LBNF1 rats received 2 ml of heparinized whole blood from Charles River (CD) rats 24 hr before heart transplantation to Lewis recipients. The transfused LBNF1 grafts had a mean survival time of 6.6 +/- 0.9 days. Therefore, donor blood transfusion does not appear to prolong graft survival in this retrospective human study or in the animal model.
