  • Title: Successful transplantation of cyclosporine-treated allograft recipients with serologically positive historical, but negative preoperative, donor crossmatches.

    Abstract:
    Eighteen renal allograft recipients (15 cadaveric and 3 haploidentical living-related donor transplants) with historically (Hx)3 positive, but pretransplant (pre-Tx) negative, donor crossmatches (XM) were treated postoperatively with cyclosporine (CsA) and prednisone (Pred). The one-year allograft survival for the 14 primary allograft recipients was 86% (12/14). This was comparable to, and not significantly different from, the 81% (51/63) graft survival for recipients of primary cadaveric donor allografts transplanted during the same period who displayed a negative donor crossmatch with both Hx and pre-Tx sera. All four retransplant recipients with (+) Hx, but (-) pre-Tx, donor Xms lost their grafts. This result was significantly different (P less than 0.05) from the 75% (27/36) graft survival for retransplant recipients displaying a negative donor crossmatch with both Hx and pre-Tx sera. A significant decrease in PRA of 52 +/- 19% to 19 +/- 16%, P less than 0.05, was displayed by 12/18 CsA patients when comparing (+) Hx to (-) pre-Tx sera, which could have influenced the allograft survival in those patients. However, a graft survival of 44% (4/9) was observed for azathioprine (Aza) and Pred-treated recipients of cadaveric donor renal allografts who also displayed a significant decrease in PRA of 50 +/- 22% to 5 +/- 4%, P less than 0.05 when comparing Hx to pre-Tx sera. The decreasing PRA did not beneficially affect these Aza-Pred patients' graft survival. Therefore, CsA-Pred afforded a beneficial effect when recipients of a primary cadaveric renal allograft displaying a (+) Hx, but (-) pre-Tx, XM were transplanted. Retransplant recipients, however, should receive a cadaveric donor allograft only when they are XM-unreactive, whether testing with pre-Tx or Hx sera.
