Background: Historically, hepatitis C virus (HCV) was difficult to treat among people with HIV. However, treatment with direct-acting antivirals (DAAs) results in 90%-95% of people being cured. There is a need to understand why a proportion of people are not cured.

Unfortunately, few existing programmes are evidence-based.

It is widely accepted that human immunodeficiency virus (HIV) infection is a risk factor for increased severity of hepatitis C virus (HCV) liver disease. However, owing to better efficacy and safety of combination antiretroviral therapy (cART), and increased access to HCV therapy, whether this condition remains true is still unknown. Overall, 1,253 HCV mono-infected patients and 175 HIV/HCV co-infected patients with cirrhosis, included in two prospective French national cohorts (ANRS CO12 CirVir and CO13 HEPAVIH), were studied.

In the ANRS CO13 HEPAVIH Cohort, HCV RNA measurement was performed with one of the two available real-time PCR assays [Roche Cobas AmpliPrep-Cobas TaqMan HCV (CAP-CTM) and the Abbott Real-Time HCV (ART)], according to the assay used in each center. To comply with the recommendations for using the same assay in multicenter clinical trials, all the 204 samples analyzed with ART were retested retrospectively by CAP-CTM. The aim of this study was to assess the usefulness of this strategy in real-life situations.

Background: In France, it is estimated that 24% of HIV-infected patients are also infected with HCV. Longitudinal studies addressing clinical and public health questions related to HIV-HCV co-infection (HIV-HCV clinical progression and its determinants including genetic dimension, patients' experience with these two diseases and their treatments) are limited. The ANRS CO 13 HEPAVIH cohort was set up to explore these critical questions.
