Planned random donor blood transfusion in preparation for transplantation. Sensitization and graft survival.
Random donor blood transfusions were used to prepare 183 prospective recipients for one-haplotype living-related donor (LRD) grafts or cadaver donor (CD) grafts. Five units of packed red blood cells were administered over a 7-10 day period, and weekly sera were monitored for six weeks. Sensitization was uncommon in men and nulliparous women (8/153), was of low reactivity, and was not a barrier to transplantation. Multiparous women had a 44% frequency of sensitization on presentation and 11/24 initially lacking cytotoxicity developed reactive serum following transfusion. Single-haplotype LRD recipients had 96% one-year graft survival. CD recipients had one-year graft survival of 72%. The rate of transplantation in surviving candidates exceeded 90%, and supports the hypothesis of a protective immune response.
