Abstract

Co-infection with Hepatitis C virus (HCV) among HIV-positive patients leads to accelerated progression of liver disease and AIDS. Due to increased HCV prevalence and incidence, co-infection requires monitoring trends among HIV-positive individuals. This will help target prevention strategies and support to reach the global goals of eliminating viral hepatitis as a public health threat. In this analysis HCV prevalence and incidence were determined for the years 1996-2019 from yearly blood samples and questionnaire details among HIV-1-positive patients, with a majority of men who have sex with men, belonging to a nationwide, multicentre observational, prospective cohort study. The results show that HCV prevalence for acute/chronic and resolved infection increased until 2014 to 12%. Since then, prevalence of acute/chronic HCV infection rapidly decreased and prevalence of resolved infections showed a steady increase. HCV incidence was highest in 2010 and lowest in 2017; however, no significant change in HCV incidence could be seen over the years. Therefore, the introduction of directly-acting antiviral agents for HCV treatment notably decreased prevalence and potentially incidence of acute/chronic HCV infection. Nevertheless, prevalence and incidence of HCV among these HIV-1-positive study participants remain high compared with the general population and justify the need for continuous HCV prevention and treatment efforts among HIV-positive individuals.
