The prevalence of hepatitis C virus (HCV) infection is increasing in HIV-positive men who have sex with men (MSM) participating in the Swiss HIV Cohort Study (SHCS). MSM with high-risk sexual behaviour are recognized to be the main drivers of the current HCV epidemic. However, in Switzerland treatment with the newest available direct acting agents (DAAs) is currently restricted to patients with a METAVIR fibrosis score ≥2 (i.e., patients with beginning or advanced liver fibrosis or cirrhosis) by the federal office of public health due to the tremendous costs of these DAAs. Within the study population (i.e. HIV-infected MSM with a replicating HCV-infection in Switzerland), about 90% of individuals have a METAVIR fibrosis score <2. As a consequence, HCV therapy with new DAAs is not covered by health insurances for the majority of this population. However, there is evidence that HCV treatment should not be delayed until the development of advanced liver disease. Treating HIV/HCV-coinfected individuals independently of their liver fibrosis score can prevent the development of liver related complications and the transmission of HCV infection.
