Sexual Hepatitis C in HIV Positive Men Who Have Sex With Men (MSM) in Bordeaux
Sexual Hepatitis C in HIV Positive Men Who Have Sex With Men (MSM) in Bordeaux
The main objective of this study is to analyse sexual behavior of HIV + MSM in Bordeaux, who
 have sexually contracted hepatitis C between January 1st 2013, to January 31, 2017. These
 data will bring some improvement about prevention and maybe reduced the hepatitis C
 incidence.
Hepatitis C (HCV) is considered in part as a sexually transmitted infection (STI). A marked
 decrease in its incidence has been observed for several years, coinciding with the
 availability of new direct acting antiviral treatments (DAA). However, people are
 increasingly infected with the hepatitis C virus, especially HIV-positive MSM. This increase
 is explained by new sexual practices that are particularly at high level of risk, despite the
 widening accessibility of new DAA. Prevention also plays an important role in implementing an
 effective risk reduction policy. New methods of prevention must therefore be developed. For
 this purpose, it is imperative to know the natural history of acute hepatitis C, the
 different behaviours at risk of HCV transmission, and the demonstration of socio-sexual
 networks (clusters) thanks to virological phylogenetic studies. In order to improve hepatitis
 C prevention, we wish to establish a descriptive study focusing on :

 -  Descriptive analysis of the natural history of hepatitis C,

 -  Identification of patient clusters (phylogenetic analysis)

 -  Description of the sexual behaviors of infected patients, through a semi-directed
 interview.
