【摘要】 目的:探讨吉林地区汉族人群乙型肝炎肝硬化患病与白细胞抗原(HLA)DRB1区等位基因多态性的关联性。方法:采用PCR-SSP方法对吉林地区汉族61例慢性乙型肝炎,44例乙型肝炎肝硬化患者,32名HBV感染自然恢复者及50名健康献血员作对照进行了HLA-DRB1等位基因分型比较。结果:慢性乙型肝炎组HLA-DRB1*1201-3等位基因表达频率为17.21%,明显高于正常对照组8.00%(P=0.0427,RR=2.391);慢性乙型肝炎组与乙型肝炎肝硬化组HLA-DRB1*0701等位基因频率分别为11.48%,12.50%,明显高于正常对照组2.00%(P=0.0066,RR=6.35;P=0.0046,RR=7.00)及HBV感染自然恢复组1.56%(P=0.0183,RR=8.17;P=0.0136,RR=9.00);而所检测HLA-DRB1座位的其它等位基因表达频率在四组间无显著性差异(P>0.05)。结论:吉林地区汉族人群慢性乙型肝炎患病与HLA-DRB1*1201-3、HLA-DRB1*0701等位基因型相关联;而乙型肝炎肝硬化患病仅与HLA-DRB1*0701等位基因型相关联。更多还原

【Abstract】 Objective:To investigate the association of human leucocyte antigen-DRB1 alleles with chronic hepatitis B and hepatic cirrhosis in Han population of Jilin area.Methods:HLA-DRB1 alleles in 61 patients with chronic hepatitis B,44 patients with hepatic cirrhosis,32 spontaneous rehabilitees after HBV infectin,and 50 healthy controls were analyzed by using polymerase chain reaction/sequence specific primer technique.Results:The frequency of HLA-DRB1*1201-3 allele in chronic hepatitis B group was higher than that in healthy control group(17.21% vs.8.00%,P=0.0427,RR=2.391).The frequency of HLA-DRB1*0701 allele in chronic hepatitis B group and hepatic cirrhosis group was markedly higher than that in healthy controls group(11.48 % vs.2.00%,P=0.006 6,RR=6.35;12.50% vs.2.00%,P=0.004 6,RR=7.00)and in spontaneous rehabilitee group (11.48% vs.1.56%,P=0.0183,RR=8.17;12.50% vs.1.56%,P=0.0136,RR=9.00).No significant differences frequencies of the other HLA-DRB1 alleles were observed among the four groups.Conclusion:Alleles of HLA-DRB1*1201-3 and HLA-DRB1*0701 are closely associated with chronic hepatitis B and maybe susceptible genes or linkage genes of chronic hepatitis B.HLA-DRB1*0701 is also closely associated with hepatic cirrhosis and maybe a susceptible gene or linkage gene-posthepatitis B-cirrhosis in Han population of Jilin area.更多还原
