摘 要:目的:研究人类白细胞抗原(human leukocyte antigen,HLA)多态性与慢性肾功能衰竭(chronic renal failure,CRF)的遗传易感性。方法:采用聚合酶链反应-序列特异引物(PCR-SSP)技术,对2002~2007年间来我室配型的377例汉族慢性肾功能衰竭患者以及1212例正常无血缘关系汉族人群进行HLA-A/B/DRB1/DQB1基因分型,并对其在CRF患者及正常人群中的基因频率、单倍型频率以及相对危险度(RR)等进行统计学分析。结果:疾病组HLA-A*02[RR(95%CI):1.3598(1.2345,1.4978)]、DRB1*04[RR(95%CI):1.3651(1.1052,1.6862)]、DRB1*12[RR(95%CI):1.3162(1.0824,1.6006)]、DQB1*0301[RR(95%CI):1.3434(1.1745,1.5367)]以及DQB1*0302[RR(95%CI):1.5330(1.1136,2.1104)]可能是慢性肾功能衰竭的易感基因,而HLA-A*11[RR(95%CI):0.5782(0.4978,0.6849)]、B*46[RR(95%CI):0.6580(0.4930,0.8082)]、DQB1*02[RR(95%CI):0.7452(0.5961,0.9317)]以及DQB1*05[RR(95%CI):0.7742(0.6470,0.9264)]可能是慢性肾功能衰竭的保护性基因。DRB1*11-DQB1*0301[RR(95%CI):1.5539(1.1896,2.0298)]、DRB1*12-DQB1*0301[RR(95%CI):1.3315(1.0869,1.6311)]、A*02-B*15[RR(95%CI):1.4654(1.0751,1.9973)]可能是慢性肾功能衰竭的易感单倍型型别。结论:慢性肾功能衰竭发生、发展与HLA基因型及其单倍型多态性有关,探讨该病与HLA多态性的易感性,对于研究CRF致病因素及治疗等具有一定意义。Objective:To study the relationship between the polymorphism of human leukocyte antigen (HLA) and genetic susceptibility for chronic renal failure (CRF). Methods:By using polymerase chain reaction sequence specific primer (PCR-SSP) method, 377 CRF patients and 1 212 unrelated donors of Han population, whose blood samples were collected during their HLA matching in our laboratory from 2000 to 2007, were HLA-A/B/DRB1/DQB1 genotyped. Then, the frequencies of HLA genotypes and haplotypes were statistically analyzed, and the relative risks (RR) for the disease were calculated between CRF patients and unrelated donors. Results: In the CRF groups, HLA-A * 02[ RR(95% CI) : 1. 3598 ( 1. 2345, 1. 4978) ], DRB1 * 04 [ RR (95% CI) : 1. 3651 ( 1. 1052, 1. 6862 ) ], DRB1 * 12 [ RR ( 95 % CI) : 1. 3162 ( 1. 0824, 1. 6006) ], DQB1 * 0301 [ RR (95% CI) : 1. 3434 ( 1. 1745, 1. 5367) ] and DQB1 * 0302 [ RR (95% CI) : 1. 5330( 1. 1136, 2. 1104) ] might be the susceptibility genes for chronic renal failure. On the other hand, HLA-A * 11 [ RR (95 % CI) : O. 5782 (0. 4978, O. 6849) ], S * 46 [ RR (95% CI) : O. 6580 (0. 4930, 0. 8082) ], DQB1 * 02 [ RR (95% CI) : O. 7452(0.5961, O. 9317) ] and DQB1 * 05[ RR (95% CI) : O. 7742(0. 6470, O. 9264) ] might be the pro- tective genes for chronic renal failure. At the same time, DRB1 * ll-DQB1 * 0301 [RR(95% CI): 1. 5539( 1. 1896, 2. 0298) ], DRB1 * 12-DQB1 * 0301 [ RR (95% CI) : 1.3315 ( 1. 0869, 1.6311 ) ] and A * 02-B * 15 [ RR (95% C I) : 1. 4654 ( 1. 0751, 1. 9973) ] might be the susceptible haplotypes for chronic renal failure. Conclusion: The results preliminarily confirm the relationship between the polymorphism of HLA and genetic susceptibility for chronic renal failure. Therefore, to study the relationship between the polymorphism of HLA and genetic susceptibility of CRF will facilitate understanding of the pathog
