[The beneficial role of blood transfusion and preganancy in the survival of renal allografts].

This analysis involves 93 cases of transplants of non-related cadaver kidneys. The result was better (p = 0.02 at 1 year) in recipients transfused before the graft (73 cases) than in those who had not been trasfused (20 cases). However, this latter group had a shorter average period of haemodialysis (p = 0.05 than the first. The benefits of pre-immunisation appear from 1 to 2 transfusions or 1 pregnancy onwards (p = 0.02 at 1 year). Subjects transfused during the 6 months prior to the transplant had a graft which was functional more often than those who had been more than 6 months before the operation (p = 0.01 at 6 months). These results would be in favour of routine small quantity transfusions, approximately every six months in patients undergoing haemodialysis and on a waiting list for transplantation.
