Brief Summary:
Two hundred and ninety-six million people worldwide are chronically infected with the hepatitis B virus (HBV), with around 750,000 deaths each year linked to the development of cirrhosis or hepatocellular carcinoma. Current treatments based on nucleoside analogues (NA) achieve virological cure in only 5% of cases at 10 years. The virological persistence of HBV is explained by the persistence of cccDNA (covalently-closed circular DNA) in the nucleus of hepatocytes. Complex and poorly understood interactions between immunological and virological responses explain the persistence of ccccDNA. A better understanding of the immunological and virological interactions of the intrahepatic compartment during chronic HBV infection is needed to better understand the mechanisms of viral persistence and for research and development of new drugs to achieve the goal of a functional cure for HBV (defined as the prolonged loss of Hepatitis B surface antigen (HBsAg) after cessation of treatment, associated with a decrease in intrahepatic cccDNA or its transcriptional inactivation).
The intra-hepatic compartment can be explored by liver biopsy. A fine needle aspiration (FNA) technique is used to characterize primary hepatic tumors, with fewer complications than liver biopsy. One study has validated its use for immunological exploration of the intra-hepatic compartment. Finally, a recently published study confirms a correlation between FNA and liver biopsy virological markers in patients with chronic HBV infection. However, no combined immuno-virological study has been carried out to explore this intra-hepatic compartment by FNA in patients with chronic HBV infection.
The investigators will assess the intrahepatic compartment of patients chronically infected with HBV (+/- hepatitis Delta (HDV)) to understand the mechanisms of viral persistence and characterize host immune responses to HBV. These investigations will make it possible to determine the immuno-virological profiles of patients who would benefit from intensification of antiviral treatment or, potentially, discontinuation of antiviral therapy.
