Background and purpose: Sofosbuvir (SOF) and daclatasvir (DCV) treatment achieves excellent efficacy and safety in treating chronic hepatitis C (CHC) with various genotypes. Real world experience of SOF/DCV regimen to treat genotype 2 CHC was scanty in Asia. This study aimed to evaluate the effectiveness and safety of SOF/DCV with or without ribavirin to treat genotype 2 CHC patients in real world practice in Taiwan. Methods: Patients with genotype 2 CHC treated with 12-week of SOF/DCV or SOF/DCV/ribavirin were enrolled prospectively. Effectiveness was evaluated by sustained virological response (SVR) which was defined as undetectable hepatitis C virus (HCV) RNA at post-treatment week 12. Adverse events were recorded for safety analysis. Results: In total of 32 patients were enrolled from October 2016 to June 2017. All were infected with genotype 2 HCV. Sixteen patients (50%) exhibited cirrhosis including 6 patients with decompensation. Regimens of SOF/DCV and SOF/DCV/ribavirin were used to treat 14 and 18 patients, respectively. SVR was achieved in all 31 patients (100%) who completed follow-up. Significantly higher levels of cholesterol (p = 0.013) and higher low density lipoprotein-cholesterol (p = 0.015) were exhibited after successful viral clearance. SOF/DCV/ribavirin regimen resulted in more adverse events, significantly higher bilirubin levels, and decline of hemoglobin during treatment than SOF/DCV regimen. Four patients with chronic kidney disease maintained renal function during treatment. Overall, SOF/DCV or SOF/DCV/ribavirin treatment was well tolerated. Conclusion: SOF/DCV with or without ribavirin is highly effective and safe for patients with genotype 2 HCV infection in real-world experience in Taiwan.
