Egypt is one of the largest epidemic areas of hepatitis C virus (HCV) in the world. Its
prevalent genotype is 4 with a majority of subtype 4a. In 2013, the Food and Drug
Administration approved a new direct-acting antiviral drug (sofosbuvir) to treat patients with
chronic HCV infection. In Egypt, the patients are already being treated with sofosbuvir in
conjunction with ribavirin and pegylated interferon alfa-2a (PEG-IFNα-2a) for 12 weeks since
2015. The present study was planned to explain the efficacy of this treatment regimen against the
HCV genotype 4a in Egyptian patients. In this population-based study, serum samples were
biochemically analyzed, and the HCV RNA levels were quantified. The sustained virological
response (SVR) was achieved following the treatment regimen. The multivariable analysis
recognized viral level of viremia and alanine aminotransferase and aspartate aminotransferase
levels affecting the virological response in patients infected with high viral load of HCV. Finally,
these results concluded that sofosbuvir with ribavirin are highly efficient in HCV Egyptian
patients where a high SVR was achieved.
