摘要: 目的 研究丙型肝炎病毒(HCV)基因型对慢性丙型肝炎(CHC)和丙型肝炎肝硬化患者接受干扰素α-2a治疗的影响。方法 2015年1月~2020年4月我院收治的CHC患者198例和丙型肝炎肝硬化患者200例,均接受肝活检和干扰素α-2a治疗24 周,随访24周。采用实时荧光定量PCR法检测血清HCV RNA水平,采用基因序列测定法检测HCV基因分型,采用单因素和多因素回归分析影响治疗应答的因素。结果 肝硬化组HCV基因1b型检出率为31.0%,显著高于86例≤S1的15.1%或112例S2~3组的18.8%(P<0.05);212例无应答组HCV基因1b型检出率显著高于186例治疗应答组(29.7%对17.7%),1a型检出率显著低于治疗应答组(17.9%对28.0%,P<0.05);应答组早期应答率为60.8%,显著高于无应答组的18.9%(P<0.05),应答组治疗前血清HCV RNA高水平比率为37.1%,显著低于无应答组的47.6%(P<0.05);HCV基因1b型(OR为0.553,95%CI为0.316~0.969)是影响干扰素治疗应答的危险因素,而早期应答(OR为1.704,95%CI为1.008~2.881)为影响干扰素治疗应答的保护因素。结论 HCV基因型可影响干扰素α-2a治疗慢性HCV感染者的应答反应,检测病毒基因型可能对选择合适的治疗方案或疗程有指导意义。

Abstract: Objective The aim of this clinical trial was to investigate the impact of HCV genotypes on the treatment response of recombinant human interferon α-2a (IFN-α-2a) in patients with chronic hepatitis C (CHC) and hepatitis C liver cirrhosis. Methods A total of 198 patients with CHC and 200 patients with hepatitis C-induced liver cirrhosis were enrolled in our hospital between January 2015 and April 2020, and all received liver biopsies and IFN-α-2a treatment for 24 weeks and followed-up for 24 weeks. Serum HCV RNA loads were detected by Roche's lightcycle real-time fluorescent quantitative PCR and the HCV genotypes were detected by gene sequencing. The liver injuries were evaluated by Knodell histological activity index scoring systems. The factors impacting response to IFN-α-2a therapy was analyzed by univariate or multivariate regression analysis. Results The percentage of HCV 1b genotype in patients with liver cirrhosis was 31.0%, significantly higher than 15.1% in 86 CHC patients with less than S1 liver fibrosis or 18.8%(P<0.05) in 112 CHC patients with S2-3 liver fibrosis; the percentage of HCV 1b genotype in 212 patients without response to IFN-α-2a therapy was significantly higher than(29.7% vs. 17.7%), and the percentage of genotype 1a was significantly lower than (17.9% vs. 28.0%, P<0.05) in 186 responders; the early virological response rate in responders was 60.8%, significantly higher than 18.9%(P<0.05), and high serum HCV RNA loads was 37.1%, significantly lower than 47.6%(P<0.05) in non-responders; the HCV 1b genotype (OR:0.553, 95%CI:0.316-0.969) was the independent risk factor, while the early response (OR:1.704, 95%CI:1.008-2.881) was the protective factor for response to IFN-α-2a therapy. Conclusion The detection of HCV genotype could predict the response to IFN-α-2a therapy in patients with CHC and CHC-induced liver cirrhosis, which might guide the selection of antiviral therapy strategy and the treatment period.
