Several studies have reported suboptimal efficacy of direct-acting antivirals (DAAs) to treat hepatitis C virus (HCV) subtypes endemic to sub-Saharan Africa (SSA) and Southeastern Asia (SEA). The extent of this issue in individuals with human immunodeficiency virus (HIV)/HCV from SSA or SEA residing in Europe is unknown.
We retrospectively analyzed data from several prospective European cohorts of people living with HIV. We included individuals with HIV/HCV who originated from SSA or SEA, were treated with interferon-free DAAs, and had an available HCV RNA result ≥12 weeks after the end of treatment. The primary outcome was sustained virological response at least 12 weeks after the end of treatment (SVR).
Of the 3293 individuals with HIV/HCV treated with DAA and with available SVR data, 142 were from SSA (n = 64) and SEA (n = 78). SVR was achieved by 60 (94% [95% confidence interval {CI}, 86%-98%]) individuals from SSA and 76 (97% [95% CI, 92%-99%]) from SEA. The genotypes of the 6 individuals failing DAA treatment were 2, 3a, 3h, 4a, 4c, and 6j. For 2 of the 4 unsuccessfully treated individuals with available sequence data at treatment failure, NS5A resistance-associated substitutions were present (30R/93S in an individual with genotype 4c and 31M in an individual with genotype 6j).
SVR rates were high in individuals with HIV/HCV residing in Europe and originating from regions where intrinsically NS5A-resistant HCV strains are endemic. HCV elimination for this population in Europe is unlikely to be hampered by suboptimal DAA efficacy.
多项研究报告称,直接抗病毒药物(DAA)治疗撒哈拉以南非洲(SSA)和东南亚(SEA)流行的丙型肝炎病毒(HCV)亚型的疗效欠佳。在欧洲居住的来自SSA或SEA的人类免疫缺陷病毒(HIV)/HCV感染者中,这一问题的严重程度尚不清楚。
我们回顾性分析了欧洲几个HIV感染者前瞻性队列的数据。我们纳入了来自SSA或SEA、接受无干扰素DAA治疗且在治疗结束后至少12周有可用HCV RNA结果的HIV/HCV感染者。主要结局是治疗结束后至少12周的持续病毒学应答(SVR)。
在3293例接受DAA治疗且有可用SVR数据的HIV/HCV感染者中,142例来自SSA(n = 64)和SEA(n = 78)。来自SSA的60例(94%[95%置信区间{CI},86%-98%])和来自SEA的76例(97%[95%CI,92%-99%])实现了SVR。6例DAA治疗失败的感染者的基因型分别为2、3a、3h、4a、4c和6j。在4例治疗失败且有可用序列数据的未成功治疗感染者中,有2例存在NS5A耐药相关替代(基因型4c感染者为30R/93S,基因型6j感染者为31M)。
居住在欧洲且来自NS5A内在耐药HCV毒株流行地区的HIV/HCV感染者的SVR率较高。欧洲该人群的HCV消除不太可能因DAA疗效欠佳而受阻。
