Abstract
BACKGROUND/ PURPOSE: The effect of sofosbuvir and daclatasvir in treatment of genotype 4 Hepatitis C Virus (HCV) is not well documented. This study investigated the safety and efficacy of sofosbuvir plus daclatasvir with or without ribavirin in treatment of HCV genotype 4 patients. The impact of therapy on liver fibrosis as well as the role of IL18 polymorphism in therapeutic outcome was assessed. METHODS: One hundred HCV genotype 4 patients were categorized into 2 groups. The group 1 comprised treatment naïve patients, with total serum bilirubin ≤ 1.2 mg/10-1 L, serum albumin ≥ 3.5 g/10-1 L, INR ≤ 1.2, and platelet count ≥ 150 × 109/L. This group was treated with sofosbuvir plus daclatasvir for 12 weeks. The group 2 included Peg-IFN-α-or sofosbuvir treatment experienced, or patients with at least 2 of the following findings: total serum bilirubin > 1.2 mg/10-1 L, serum albumin < 3.5 g/10-1 L, INR > 1.2, and platelet count < 150 × 109 L-1. Group 2 was treated with sofosbuvir-daclatasvir + ribavirin for 12 weeks, with the exception of sofosbuvir treatment experienced patients, who were treated with sofosbuvir/daclatasvir + ribavirin for 24 weeks. RESULTS: Sustained Virological Response (SVR12) (undetectable viremia12 weeks post-treatment), was 93.3% in group 1 and 87.5% in group 2 (total = 91%). Such high efficacy was accompanied with tolerable adverse effects as well as with significant improvement in liver fibrosis. No significant association was observed between IL18 polymorphism (rs1946518) at position -607 and achievement of SVR12 in HCV patients after treatment. CONCLUSION: Sofosbuvir plus daclatasvir, with or without ribavirin achieved high efficacy and safety in HCV genotype 4 patients. Their effects were accompanied with attenuation of liver fibrosis. Further wider-scale studies are needed to evaluate the actual role of IL18 polymorphisms in treatment response with sofosbuvir/daclatasvir.
