French HIV-HBV Cohort (COVViB)

25. april 2018 opdateret af: Institut de Médecine et d'Epidémiologie Appliquée - Fondation Internationale Léon M'Ba

Multi-center Study Evaluating Persistence of Hepatitis B Virus Replication, Long-term Prognostic Indicators and Their Clinical Relevance in Patients Co-infected With the Human Immunodeficiency Virus and Chronic Hepatitis B

The overarching purpose of this study is to further understand the reasons for and clinical implications of persistent HBV infection in patients co-infected with HIV and HBV in the era of highly effective antiviral treatment against both viruses.

Detaljeret beskrivelse

The French HIV-HBV Cohort is an observational, non-interventional study including 308 HIV-infected patients with chronic HBV infection (HBsAg-positive serology >6 months) in seven clinical centers. Patients were recruited in 2002-2003 and followed prospectively every three to twelve months, during two phases, until 2010-2011. Extensive information on a variety of HIV- and HBV-related parameters were collected during these study visits.

This particular study aims to extend follow-up of the French HIV-HBV Cohort using a different type of design. Patients who completed at least one study phase of the French HIV-HBV Cohort are selected for participation. Patients continuing follow-up at a participating clinical center are asked to undergo their routine clinical visit, during which time medical data from the years since last cohort visit until their routine visit are extracted. For those who died, information from the years since last cohort visit until death will be collected.

The primary objective for this cohort extension is to further understand the reasons for and clinical implications of persistent HBV infection in patients co-infected with HIV and HBV in the era of highly effective antiviral treatment against both viruses.

The following secondary objectives are as follows:

  • To establish the extent of persistent viremia (PV) of HBV, quantified either in serum or within the hepatocyte
  • To understand whether this persistence effects clinically-relevant serological outcomes (i.e. HBeAg and HBsAg seroclearance and seroconversion along with HBsAg quantification) after prolonged follow-up
  • To quantify the evolution of liver fibrosis using non-invasive methods and, in a small subset of patients, liver biopsies, while investigating the virological and immunological factors associated with its progression and regression
  • To describe the causes of liver-related and non-liver-related morbidity and mortality and the direct effect of persistent HBV DNA replication on these outcomes
