Author Interviews, Coffee, Gastrointestinal Disease, Hepatitis - Liver Disease / 03.10.2017 Interview with: Patrizia Carrieri PhD INSERM U912 - ORS PACA IHU - Faculté de Médecine Marseille, France What is the background for this study? What are the main findings? Response: This study is based on the longitudinal data of the French  ANRS HEPAVIH cohort of patients with HIV and Hepatitis C co-infection. This cohort was set up thanks to a collaboration between INSERM (National Institute of health and medical research) UMR912 in Marseille, the ISPED (public health and epidemiology institute) in Bordeaux and several hospital/university sites. Our INSERM team in Marseille is specialized in the study of the impact of behaviors on HIV and HCV outcomes, including mortality. We could think that HCV cure was enough to reduce mortality in HIV-HCV patients as the mortality risk was 80% lower in those who were cured of (i.e. who “cleared”) Hepatitis C thanks to treatment. However, our study showed that, even after HCV cure, sociobehavioral factors still matter: drinking at least 3 cups of coffee a day was associated with a 50% reduction in mortality risk as well as not smoking which was also associated with a reduced mortality risk. This association between elevated coffee intake and reduced mortality risk is probably due to the properties of polyphenols contained in coffee which can protect the liver and also reduce inflammation.
