Application of human leukocyte antigen and cross-reactive group matching in clinical renal transplantation / 中华泌尿外科杂志

ABSTRACT

Objective To investigate the application and significance of human leukocyte antigen (HLA) and cross reactive groups(CREGs) matching in clinical renal transplantation. Methods A total of 312 cases of kidney transplantation were divided into two groups.In one group of 149 cases of kidney transplantations,ClassⅠCREGs matching criteria were applied instead of conventional HLA A,B matching which had two A,B mismatches(MM).In the other group of 163 cases of kidney transplantation there were A,B 0～2MM by the conventional criteria.The graft survival rate at 1 year and incidence of acute rejection within 1 month after transplantation were compared between the 2 groups. Results The percentages of HLA Ⅰ antigens 0,1,2MM were 16.7%,41.6% and 34.2% by CREGs matching criteria,and were 6.7 %,21.5% and 71.8% by conventional matching criteria.The matching rates in CREGs 0,1MM group were significantly higher than those in corresponding conventional matching group ( P 0.05);however,the incidence rate of CREGs 0MM group was obviously lower than that of A,B 2MM group ( P 0.05 ),but the rate of CREGs 0MM group was obviously higher than that of A,B 2MM group ( P
