Genotype 3 is a common type of HCV infection, and standard therapy using pegylated interferon (PEG-IFN) and ribavirin (RBV) is quite effective in these patients. While a short course of 16 similar to weeks may result in comparable end of therapy responses, relapse rates are often high. A 24-week course is therefore preferable, and is expected to result in sustained virological response (SVR) rates of more than 70%. The 24-week course is especially recommended in the presence of steatosis (often associated with Genotype 3 infection), fibrosis stage two or more, high BMI and high viral load. In patients who do not achieve a rapid viral response (RVR) with combination therapy, an extended course up to 48 similar to weeks should be considered. While not as definite as for genotype 1 patients, the presence of the CC variant of IL28b could help in the initial prognosis and the need for additional treatment, if an RVR is not achieved. The role of directly acting antiviral agents (DAA) has not been fully evaluated in treatment naive, non-responders and relapsers in genotype 3 patients. Initial results with the cyclophilin inhibitor Debio-025 are quite encouraging. There is an urgent need for large clinical trials using DAA and host modulators in patients with G3 infection.
