Supplementary data: Decreased efficacy of sofosbuvir/velpatasvirin HIV patients coinfected with HCVgenotype 3b

Aim: To retrospectively assess the efficacy and safety of sofosbuvir/velpatasvir for hepatitis C virus (HCV) genotype 3b in HIV-infected patients receiving antiretroviral therapy (ART) treatment of lamivudine/tenofovir disoproxil fumarate/efavirenz. Methods: The primary end point of HCV treatment was estimated by sustained virologic response 12 weeks after treatment (SVR12). Results: Sixteen subjects who were followed up for 48 weeks after treatment were included. The SVR12 and SVR48 were 87.5% (95% CI: 60.4–97.8%) and 81.3% (95% CI: 53.7–95.0%), respectively. One patient experienced persistent low-level viremia of HIV after 12 weeks of treatment. Conclusion: Twelve weeks of SOF/VEL is safe but has limited efficacy for HCV GT3b in HIV-infected patients receiving ART regimen including efavirenz, especially among patients with baseline HCV RNA≥6.0 log10 IU/ml.
