Efficacy and tolerability of daclatasvir/sofosbuvir (datex) in patients with HIV-HCV co-infection

Abstract

Background: Treatment of hepatitis C virus (HCV) infection with direct-acting antiviral agents in patients with HCV/human immunodeficiency virus (HIV) co-infection remains controversial due to drug interactions with antiretroviral therapy (ART). Objectives: In this study, we assessed the efficacy and tolerability of daclatasvir/sofosbuvir (DCV/SOF) in patients with HIV-HCV coinfection in the real-life setting in Iran. Methods: A total of 44 patients with HCV-HIV co-infection (genotypes 1, 3, and 4) were treated with DCV/SOF-RBV (ribavirin) (doseadjusted DCV for concomitant ART). Assessment of risk factors, sustained virologic response at 12 weeks after the end of treatment (SVR12), safety, and serum CD4 count was performed. Results: Most patients were male (95.2%). Four patients were HCV treatment-experienced cases, and 15 had cirrhosis or advanced fibrosis. The most common genotype was 3 (53.5%), followed by 1 (44.2%) and 4 (2.3%). HIV-1 RNA < 50 copies/mL and CD4 count > 250 cells/mm3 were observed in 81.8% and 79.1% of patients, respectively. The highest risk factor was a history of IV drug use (81.8%), followed by using a common syringe (77.3%) and tattooing (70.5%). All patients with or without cirrhosis (100%) completed theHCVtreatment course and achieved SVR12. Also. 92.6% of patientsonART hadCD4count> 250 cells/mm3 at the end of treatment. The HCV treatment regimen was well-tolerated. Moreover, 15.9% of patients experienced adverse events (AEs), including anorexia, nausea, diarrhea, palpitations, and anxiety. No serious AEs or discontinuation due to AEs were reported. Conclusions: Our study showed excellent tolerability and efficacy of DCV/SOF-RBV in HIV-HCV co-infected patients with or without cirrhosis.
