    Abstract:
    The functional survival rates of kidney grafts from zero-HLA haplotype-matched sibling pairs are similar to one-haplotype-matched pairs and superior to cadaver grafts. From January 1980 to March 1988, 318 primary renal transplants from sibling donors (151 matched for two, 130 for one, and 37 for zero HLA haplotypes), and 352 cadaver graft transplants were performed at the University of Minnesota. The renal graft survival rates at two years were 94%, 91%, and 94% for the 2, 1, and 0-haplotype pairs versus 75% for cadaver graft recipients (P less than 0.04). When analyzed across the different immunosuppression protocols the same trends held up, similar graft functional survivals for 1- and 0-haplotype-matched pairs both being superior to cadaver graft recipients. The graft functional survival rates at two years of recipients of 0-haplotype-matched sibling donor grafts (n = 37) was 94% versus 80% for recipients of cadaver donor grafts matched for greater than or equal to 4 HLA antigens. In addition, for recipients of 0-haplotype-matched grafts, hospital stay was shorter, fewer patients required dialysis posttransplant, and, despite a slightly higher incidence of rejection episodes (51% versus 40%, P = ns), the creatinine values one year posttransplant were significantly lower (1.5 mg/dl versus 1.9 mg/dl, P less than 0.02) than those of recipients of cadaver grafts matched for greater than or equal to 4 HLA antigens. These data support the use of cadaver grafts for patients not having a willing sibling donor, and the use of all willing sibling donors, whether or not they are a zero-haplotype match, for patients fortunate to have that family commitment.
