Abstract
Background: The introduction of direct-acting antiviral agents, has revolutionized the treatment for chronic HCV with higher cure rates, shorter duration of treatment and more tolerability have been achieved.
Objectives: The aim of our study is to estimate the efficacy and safety of DAAs in treatment of chronic HCV in patients co-infected with HIV.
Patients and Methods: This study of previously untreated patients with HCV and HIV coinfection conducted at Abbasia Fever Hospital, from July 2019 to February 2020. Patients included those who are chronic HCV infection and receiving antiretroviral therapy with a CD4 T-lymphocyte count of 200 cells/mL or greater. Serial measurements of safety parameters, virologic and host immune correlates, and adherence were performed during treatment by combination of daclatasvir 90mg and sofosbuvir 400mg+/- ribavirin 800mg daily for 12 weeks.
Results: In this study, AST & ALT were significantly decreased at end of treatment and 12 weeks after treatment, CD4 count was significantly increased. Otherwise there are no significant changes in both hematological and biochemical laboratory results. The demographic features of the patients and HIV disease characteristics were not predictors of HCV treatment failure.
Conclusion: More studies on larger numbers of patients are required for proper evaluation of the safety and efficacy of direct acting antiviral agents generally and sofosbuvir plus daclatasvir combination particularly in HIV/HCV coinfected patients. Longer follow-up studies are still recommended to fully understand the impact of sustained virological response on dynamics of liver fibrosis, biochemical profile and rate of relapse.
