摘要: 目的 探讨人类白细胞抗原(HLA)-DRB1、DQB1基因多态性与新疆维吾尔族人群结核病易感性的关联。 方法 采用病例-对照的研究方法,应用聚合酶链反应-序列特异性引物(PCR-SSP)技术对226例新疆维吾尔族肺结核病患者(肺结核病例组)和231例新疆维吾尔族健康对照者(健康对照组)进行HLA-DRB1、DQB1基因分型,比较其等位基因频率(GF),并计算其比值比(OR)。 结果 1. 肺结核病例组中HLA-DRB1*11基因频率显著高于健康对照组,2组的GF分别为4.5%、1.1%,差异有统计学意义(OR=4.388,95%CI=1.618~11.905,Pc<0.05);肺结核病例组中HLA-DRB1*04基因频率显著高于健康对照组,2组的GF分别为12.8%、8.4%,但P值经过校正后差异无统计学意义(OR=1.686,95%CI=1.060~2.684,Pc>0.05)。 2. 肺结核病例组中HLA-DQB1*0201基因频率显著高于健康对照组,2组的GF分别为40.1%、19.2%,差异有统计学意义(OR=3.379,95%CI=2.302~4.960,Pc<0.05); 肺结核病例组中HLA-DQB1*0301/4基因频率显著低于健康对照组,2组的GF分别为6.2%、10.3%,但P值经过校正后差异无统计学意义(OR=0.561、95%CI=0.334~0.941,Pc>0.05)。 结论 HLA-DRB1*11、DQB1*0201等位基因与新疆维吾尔族人群结核病强相关,DRB1*11、DQB1*0201可能是其易感基因。

Abstract: Objective To explore the correlation between the polymorphism of HLA-DRB1、DQB1 genes and the susceptibility to pulmonary tuberculosis (PTB) in a Uyghur population from Xinjiang.  Methods Using case-control study, HLA-DRB1、DQB1 genotypes in 226 PTB cases and 231 healthy controls from Uyghur population in Xinjiang were analyzed with polymerase chain reaction-sequence specific primers (PCR-SSP), in which gene frequency (GF) and odds ratio (OR) were calculated and compared.  Results 1.The frequency of HLA-DRB1*11 gene in PTB cases was significantly higher than that in the healthy controls (OR=4.388, 95%CI=1.618—11.905, Pc<0.05), their GFs were 4.5% and 1.1% respectively. The frequency of HLA-DRB1*04 gene in PTB cases was higher than that in the healthy controls, but there was the statistical difference (OR=1.686, 95%CI=1.060—2.684, Pc>0.05), their GFs were 12.8% and 8.4% respectively.   2. The frequency of HLA-DQB1*0201 gene in PTB cases was significantly higher than that in the healthy controls (OR=3.379, 95%CI=2.302—4.960, Pc<0.05), their GFs were 40.1% and 19.2% respectively. The HLA-DQB1*0301/4 gene occurred less frequently in TB patients than in controls, but there was the statistical difference (OR=0.561, 95%CI=0.334—0.941, Pc>0.05), their GFs were 6.2% and 10.3% respectively.  Conclusion HLA-DRB1*11 and DQB1*0201 alleles were evidently correlated to the incidence of tuberculosis, maybe susceptible genes of tuberculosis in Xinjiang Uyghur population.
