Approximately 3% of the population worldwide is infected with Hepatitis C Virus (HCV). Different regimens have been used to treat HCV, each of which has its side effects and efficacy. Sofosbuvir, a direct-acting antiviral drug, has replaced all previous regimens with the highest response rate. However, its response is not fully covered in Pakistan, especially Khyber Pakhtunkhwa. Objectives: The study aimed to examine the response to Sofosbuvir and Ribavirin combination therapy in chronic HCV

The patients were enrolled from January 2016 to March 2017. A total of 80 patients (57 naïve and 23 non-responder) were enrolled in this study. The age range was 16 - 70 years, and the mean age was 36 ± 2 years. Genotyping, biochemical profile, PCR tests, and liver ultrasounds were done for all of the enrolled subjects at the start and end of therapy. All patients were given direct-acting antiviral drugs for six months and then, the end of treatment response was noted. Results: A total of 80 subjects with HCV infection took part in the study, including 57 (71.25%) treatment-naïve and 23 (28.75%) treatment non-responding patients. The end of therapy response was reported after 24 weeks of treatment. Among the 80 patients, 72 (90%) patients achieved the end of therapy response. The highest end of therapy response (100%) was noted in genotype 1 and mixed genotypes and patients with normal liver ultrasound. The lowest end of therapy response (70%) was found in un-type genotype and patients with an abnormal texture of liver ultrasound. The end of therapy response rate was higher in females than in males. Conclusions: In the current study, the minimal response was found in un-type genotypes and genotypes that did not respond to INF, as compared to treatment-naïve subjects. Further research is needed to understand the relevant host and viral factors, with particular attention to relapsed patients and non-responders that are difficult to treat in the Pakistani population.
