title: Renal retransplantation in patients with HLA-antibodies.
abstract: The results of 92 consecutive renal retransplantations, performed during a 5-year period in recipients with HLA-antibodies, were retrospectively analysed. The actuarial 1-year graft survival (1-y GS) was 65% for all retransplantations, as compared with 63% for first grafts in sensitized recipients. For the second (n = 56), third (n = 24) and fourth-fifth (n = 12) grafts 1-y GS was 64%, 71% and 58%, respectively. Acute rejection was the major cause of graft loss (45%). Recipients with > 3 years GS of the preceding transplant had significantly better GS at retransplantation. Also, grafts with no HLA mismatches had significantly prolonged GS. One-y GS was 78% when PRA (panel reacting antibody) was less than 50%, and 60% when PRA was more than 50%. A benefit of repeated mismatches was demonstrated in the subgroup with PRA < 50%, in contrast to recipients with PRA > 50%, suggesting that, in some patients, an absence of antibody response against certain antigens might be used as a basis for future deliberate mismatching.
