RESUMO
OBJECTIVES: Our objective was to identify patient factors associated with being untreated for hepatitis C virus (HCV) infection in HIV-coinfected patients. METHODS: A prospective longitudinal study was carried out. HIV-infected patients with active chronic HCV infection included in the HERACLES cohort (NCT02511496) constituted the study population. The main study outcome was receipt of HCV direct-acting antiviral (DAA) treatment from 1 May 2015 to 1 May 2017. The population was divided into patients who were receiving HCV treatment during follow-up and those who were not. RESULTS: Of the 15 556 HIV-infected patients in care, 3075 (19.7%) presented with chronic HCV infection and constituted the study population. At the end of the follow-up, 1957 patients initiated HCV therapy (63.6%). Age < 50 years, absence of or minimal liver fibrosis, being treatment-naïve, HCV genotype 3 infection, being in the category of people who inject drugs using opioid substitutive therapy (OST-PWID), and being in the category of recent PWID were identified as significant independent risk factors associated with low odds of DAA implementation. When a multivariate analysis was performed including only the PWID population, both OST-PWID [odds ratio (OR) 0.552; 95% confidence interval (CI) 0.409-0.746) and recent PWID (OR 0.019; 95% CI 0.004-0.087) were identified as independent factors associated with low odds of treatment implementation. CONCLUSIONS: We identified factors, which did not include prioritization of a DAA uptake strategy, that limited access to HCV therapy. The low treatment uptake in several populations seriously jeopardizes the elimination of HCV infection in the coming years.
