To evaluate a decentralised testing model and simplified treatment protocol of hepatitis C virus (HCV) infection to facilitate treatment scale-up in Myanmar, this prospective, observational study recruited HIV-HCV co-infected outpatients receiving sofosbuvir/daclatasvir in Yangon, Myanmar. The study examined the outcomes and factors associated with a sustained virological response (SVR). A decentralised "hub-and-spoke" testing model was evaluated where fingerstick capillary specimens were transported by taxi and processed centrally. The performance of the Xpert HCV VL Fingerstick Assay in detecting HCV RNA was compared to the local standard of care ( plasma HCV RNA collected by venepuncture). Between January 2019 and February 2020, 162 HCV RNA-positive individuals were identified; 154/162 (95%) initiated treatment, and 128/154 (84%) returned for their SVR12 visit. A SVR was achieved in 119/154 (77%) participants in the intent-to-treat population and 119/128 (93%) participants in the modified-intent-to-treat population. Individuals receiving an antiretroviral therapy were more likely to achieve a SVR (with an odds ratio (OR) of 7.16, 95% CI 1.03-49.50), while those with cirrhosis were less likely (OR: 0.26, 95% CI 0.07-0.88). The sensitivity of the Xpert HCV VL Fingerstick Assay was 99.4% (95% CI 96.7-100.0), and the specificity was 99.2% (95% CI 95.9-99.9). A simplified treatment protocol using a hub-and-spoke testing model of fingerstick capillary specimens can achieve an SVR rate in LMIC comparable to well-resourced high-income settings.
为评估一种针对丙型肝炎病毒 (HCV) 感染的去中心化检测模型和简化治疗方案,以促进缅甸的治疗扩大化,本前瞻性观察性研究招募了在仰光接受索磷布韦/达卡他韦治疗的 HIV-HCV 合并感染门诊患者。该研究检测了持续病毒学应答 (SVR) 的结果和相关因素。评估了一种去中心化的“中心辐射”检测模型,即通过出租车运输指刺毛细血管标本并进行集中处理。检测了 Xpert HCV VL 指刺检测法检测 HCV RNA 的性能,并与当地的护理标准(静脉穿刺采集的血浆 HCV RNA)进行了比较。2019 年 1 月至 2020 年 2 月期间,共发现 162 例 HCV RNA 阳性个体;其中 154/162(95%)开始治疗,128/154(84%)返回进行 SVR12 访视。意向治疗人群中,119/154(77%)参与者和改良意向治疗人群中,119/128(93%)参与者获得 SVR。接受抗逆转录病毒治疗的个体更有可能获得 SVR(比值比 [OR] 为 7.16,95% CI 1.03-49.50),而肝硬化患者则不太可能获得 SVR(OR:0.26,95% CI 0.07-0.88)。Xpert HCV VL 指刺检测法的灵敏度为 99.4%(95% CI 96.7-100.0),特异性为 99.2%(95% CI 95.9-99.9)。使用指刺毛细血管标本的中心辐射检测模型简化治疗方案,可在资源有限的中低收入国家实现与高收入资源丰富国家相当的 SVR 率。
