    Abstract:
    A retrospective analysis of 300 consecutive cadaveric renal allografts performed at our institution between August 1, 1981, and December 1, 1983, was performed to evaluate the influence of DR typing on graft and patient survival. All patients were treated with low-dose steroids and cyclosporine as the only means of immunosuppression. The group included 246 primary graft recipients and 54 retransplants. DR information was available on the donor and the recipient in 225 of these patients, and it was unavailable on the donor and/or recipient in 75 patients. In 49% of the cases in which information was available, 2 alleles were identified in the donor and in the recipient; in the remainder only 1 allele was identified in either the donor or recipient. The results were analyzed according to HLA/DR match and mismatch. Twelve-month graft survival for the 2-DR-match recipients was 67%, versus 78% for the 1-DR match and 76% for the O-DR match. These differences were not significant. For the O-DR mismatch, the one-year actuarial graft survival was 74%, for the 1-DR mismatch 78%, and for the 2-DR mismatch 79%. Again, there was no significant difference. There was no impact of DR matching on patient or graft survival up to 18 months. Additionally, no difference was found in any of the groups regarding the number of treated rejection episodes per patient or the amount of steroid received per patient at the end of a year. These results suggest that cyclosporine negates the effect of DR matching in cadaveric renal transplantation.
