Generic sofosbuvir and daclatasvir for treatment of hepatitis C virus infection in patients with sickle cell disease

Background and purpose of the studySickle cell disease (SCD) patients are at a high risk of chronic liver disease (CLD) due to chronic viral hepatitis infection such as hepatitis C virus (HCV) infection, iron overload, and sickle cell hepatopathy. Nowadays, several oral direct-acting antiviral drugs (DAAs) have been developed and approved by the FDA for hepatitis C treatment. However, the safety and efficacy of DAAs in SCD patients remain insufficiently explored.Purpose of the studyTo evaluate the efficacy and safety of administration of generic sofosbuvir (SOF) and daclatasvir (DCV) for 12 weeks in SCD patients infected with HCV.MethodsA retrospective study included 38 SCD patients infected with HCV treated with generic SOF (400 mg) and DCV (60 mg) for 12 weeks without ribavirin. The effectiveness of the HCV treatment was assessed by the sustained virologic response (SVR) at 24 weeks after the end of the treatment (SVR24).ResultsThe SVR24 rate was 100% (38/38).There were insignificant alterations in hemoglobin and total bilirubin levels during HCV treatment or at end of treatment (EOT). The number of anemic patients who needed blood transfusion two weeks before HCV treatment, at week 4 of treatment, and at EOT was 11 (28.9%), 3 (8%), and 1 (3%) respectively. Moreover, the reductions in serum transaminase levels from baseline were statistically significant compared to the EOT.ConclusionGeneric SOF and DCV regimens appear to be safe and effective in the treatment of chronic HCV in patients with SCD.
