摘要 目的观察肾移植供受者自然杀伤细胞免疫球蛋白样受体(KIR)配体HLA-Bw4 I80相关基因配型情况,分析错配对移植效果的影响。方法用序列特异性引物-聚合酶链反应方法(PCR-SSP)检测223对肾移植供受者的KIR基因型,判断供受者间KIR配体HLA-Bw4 I80相关基因配型情况;观察受者近期移植肾功能延迟恢复(DGF)、急性排斥反应(AR)发生情况,术后随访5年判断移植肾及受者存活情况。结果 223对供受者中,KIR配体HLA-Bw4 I80相关基因配型相合55对(24. 67%)、错配168对(75. 33%),错配是相合的3倍。错配与相合的肾移植受者术后AR发生率、1年移植肾存活率、5年受者存活率比较,差异均无统计学意义;错配者肾移植受者术后DGF发生率高于相合者,5年移植肾存活率低于相合者(P均<0. 05)。结论肾移植供受者KIR配体HLA-Bw4 I80相关基因实际错配概率较高;错配可增加肾移植术后受者DGF发生率,导致移植肾长期存活率下降。
