[Effect of HLA matching in renal transplantation].
Evaluation of HLA-matching is useful in determining graft function and survival in a recipient in cadaveric renal transplantation. The effects of HLA on graft function, which serum creatinine indicative of, and graft survival were examined in both living and cadaveric transplantation in 280 Japanese renal transplants performed at Osaka University and Osaka Prefectural Hospital between October, 1982 and December, 1991 (cadaver 68, living 212). HLA-DR mismatch had a strong effect in living transplants, whereas no disparity was found in cadaver transplants with HLA-DR mismatch. HLA-B, DR mismatch had more effect than HLA-DR in cadaver transplants, and the same effect as HLA-DR in living transplants. HLA-AB affected graft function. It can be used to predict the effect of long-term graft survival. The HLA-haplotype match had the strongest association with graft survival and function in both cases of living and cadaver transplants. HLA-haplotypes of a cadaveric donor and a recipient were presumed by means of the linkage disequilibrium. These findings showed that HLA-matching, especially of haplotype, is an essential factor in relatively low risk renal transplant survival and function. 1-haplotype-matched transplantation, determined by the family study or presumed by the linkage disequilibrium is recommended if not 2-haplotype matched.
