摘要:

目的 探讨新疆地区慢性丙型肝炎患者病毒基因型、病毒载量对丙型肝炎病毒(HCV)抗体S/CO值、肝酶、外周血T淋巴细胞亚群的影响。方法 收集2014年1月至2015年9月新疆医科大学第一附属医院慢性丙型肝炎住院患者106例、体检正常者(正常对照组)30名,分别采用化学发光法、酶法、荧光定量逆转录聚合酶链反应(PCR)、PCR-反向点杂交技术和流式细胞术对106例慢性丙型肝炎患者的血清样本进行HCV抗体、肝酶[丙氨酸氨基转移酶(ALT)、天门冬氨酸氨基转移酶(AST)]、HCV RNA、HCV基因分型以及外周血T淋巴细胞检测。结果 1b、2a、3a和3b基因型慢性丙型肝炎患者间HCV抗体S/CO值、ALT、CD8+T淋巴细胞百分数差异有统计学意义(P<0.05)。病例数较多的1b、2a基因型慢性丙型肝炎患者CD4+T淋巴细胞百分数、CD4/CD8比值均低于正常对照组[CD4+T淋巴细胞百分数分别为(39.05±9.42)%、(38.65±10.26)%、(42.45±4.61)%,CD4/CD8比值分别为1.60±0.64、1.53±0.66、2.31±0.25],CD8+T淋巴细胞百分数[(26.79±7.58)%、(27.15±10.40)%]则高于正常对照组[(18.36±3.88)%,P<0.05]。将慢性丙型肝炎患者按HCV RNA载量水平分为4组,各组间HCV抗体S/CO值、肝酶水平及CD4/CD8比值差异有统计学意义(P<0.05)。结论 新疆地区慢性丙型肝炎患者病毒基因型以1b、2a型为主,不同基因型及病毒载量患者HCV抗体S/CO值、外周血T淋巴细胞亚群及肝酶水平存在差异,具有一定的相关性。

Abstract:

Objective To investigate the influence of genotype and viral load on hepatitis C virus(HCV) antibody S/CO ratio,liver enzymes and peripheral blood T lymphocyte subsets among patients with chronic HCV infection in Xinjiang.Methods A total of 106 outpatients and inpatients from the First Affiliated Hospital of Xinjiang Medical University were enrolled from January 2014 to September 2015,and 30 healthy subjects were enrolled as healthy control group. HCV antibody,liver enzymes [alanine aminotransferase(ALT) and aspartate aminotransferase(AST)],HCV RNA,HCV genotype and peripheral blood T lymphocyte subsets were determined by chemiluminescence,enzymatic analysis,fluorescence quantitation reverse transcription polymerase chain reaction(PCR),PCR-reverse dot blot hybridization and multi-color flow cytometry. Results There was statistical significance in HCV antibody S/CO ratio,ALT and the percentage of CD8+T lymphocyte among 1b,2a,3a and 3b genotypes(P<0.05). The percentages of CD4+ T lymphocyte and CD4/CD8 ratio in 1b and 2a genotypes were lower than those in healthy control group [CD4+T lymphocyte percentages were(39.05±9.42)%,(38.65±10.26)% and(42.45±4.61)%,and CD4/CD8 ratios were 1.60±0.64,1.53±0.66 and 2.31±0.25],and the percentages of CD8+ T lymphocyte [(26.79±7.58)% and(27.15±10.40)%] were higher than those in healthy control group [(18.36±3.88)%,P<0.05]. According to HCV RNA load for classification,there was statistical significance for HCV antibody S/CO ratio,liver enzymes and CD4/CD8 ratio(P<0.05). Conclusions HCV 1b and 2a genotypes are main genotypes for patients with chronic HCV infection in Xinjiang. Viral load and different genotypes may affect HCV antibody S/CO ratio,liver enzymes and peripheral blood T lymphocyte subsets.
