Impact of Rh(D) blood group system on graft function and survival in live-donor kidney transplantation: a single-institution experience.

One thousand five hundred consecutive live-donor renal transplants were performed in a single institution. Among these patients, 1,372 patients (group I) received Rh-identical allografts and 128 (group II) received Rh-nonidentical allografts. The two groups were homogenous apart from the prevalence of the Rh nonidentity among unrelated donor-recipient pairs. The rate of acute and chronic rejection was comparable in both groups (P = 0.33 for acute rejection and P = 0.66 for chronic rejection). The mean serum creatinine at 5 years was 1.8 +/- 1 mg/dL for group I and 1.7 +/- 0.9 mg/dL for group II (P = 0.5). The 1-, 5-, and 10-year graft survival rates were 94%, 78%, and 54% for group I and 95%, 82%, and 57% for group II. We found that the Rh(D) blood group system is not likely to be a clinically relevant histocompatibility barrier to live-donor renal transplantation.
