Chronic hepatitis C virus infection is one of the most important health problems in Egypt. The purpose of this study was to assess the efficacy, and tolerability of two therapeutic modalities, dual (Sofosbuvir+ribavirin)and triple (sofosbuvir + ribavirin + peg-interferon), in treating Egyptian patients infected with HCV genotype-4. In addition, we determined serum IL-12p70 and TLR7 gene expression in patients infected with HCV with and without treatment, compared to the normal volunteers. No significant changes in serum creatinine and fasting blood glucose concentrations were reported at the end of the treatment with dual and triple therapy and after 3 months of follow up. Pateints infected with HCV showed a non significant change in the relative quantitation of TLR7 gene expression, and a significant elevation in serum IL-12p70 concentration (161.73%, p
