Abstract

Objective To assess the geographic distribution of HCV genotypes, effectiveness, and safety of DAA treatment for HCV-infected patients in North and Northeast China. Methods The geographic distribution of HCV genotypes was analyzed in 2162 patients recruited from April 2018 to February 2021. Sustained virologic response rates at 12 (SVR12) or 24 (SVR24) weeks posttreatment and safety were analyzed in 405 patients who completed DAA treatment according to patient baseline characteristics and treatment. Results Four genotypes and six subtypes were identified as follows: 1b (1187, 54.90%), 2a (790, 36.54%), 3a/b (134, 6.20%), 6a/n (44, 2.04%), mixed genotypes (2a-6a or 2a-3a) (7, 0.32%). Overall, 99.01% patients achieved SVR12, while 98.43% achieved SVR24. All patients treated with elbasvir/grazoprevir (EBR/GZR), sofosbuvir/velpatasvir ± ribavirin (SOF/VEL ± RBV), and SOF/ledipasvir (LDV) achieved SVR12 or SVR24; 92.86% SVR12 and 95.83% SVR24 were observed in patients using SOF + RBV. SVR12 was higher in noncirrhosis versus compensated cirrhosis patients (100% vs. 97.09%, p=0.022). No severe drug-related adverse event was observed. Conclusions Genotypes 1b and 2a were dominant subtypes in North and Northeast China. The approved drug regimens EBR/GZR and SOF/LDV for subtype 1b and SOF/VEL for nongenotype 1b are the optimal effective and safety profile.
华北和东北地区慢性HCV感染患者HCV基因型的地理分布和直接作用抗病毒药物的疗效:一项真实世界的多中心研究
目的评估华北和东北地区HCV基因型的地理分布、DAA治疗HCV感染患者的有效性和安全性。方法分析2018年4月至2021年2月招募的2162例HCV基因型患者的地理分布。根据患者基线特征和治疗,分析405例完成DAA治疗的患者在治疗后12周(SVR12)或24周(SVR24)的持续病毒学缓解率和安全性。结果共鉴定出4个基因型和6个亚型:1b(1187, 54.90%)、2a(790, 36.54%)、3a/b(134, 6.20%)、6a/n(44, 2.04%)和混合基因型(2a-6a或2a-3a)(7, 0.32%)。总体而言,99.01%的患者达到SVR12, 98.43%的患者达到SVR24。所有接受elbasvir/grazoprevir (EBR/GZR)、sofosbuvir/velpatasvir±利巴韦林(SOF/VEL±RBV)和SOF/ledipasvir (LDV)治疗的患者均达到SVR12或SVR24;SOF + RBV组SVR12和SVR24分别为92.86%和95.83%。非肝硬化患者的SVR12高于代偿性肝硬化患者(100% vs. 97.09%, p=0.022)。未观察到严重的药物相关不良事件。结论基因型1b和2a是华北和东北地区的优势亚型。已批准的治疗1b亚型的药物方案为EBR/GZR和SOF/LDV,治疗非基因型1b的药物方案为SOF/VEL,具有最佳的有效性和安全性。
