Evaluation of cccDNA and Total HBV DNA Kinetics in Lymphocytes, Total Blood and Serum in Chronic Hepatitis B Patients Treated With Adefovir Dipivoxil and Peg Interferon Alpha 2a

Overview

Serum HBV DNA is a referent but insufficient marker of therapeutic follow-up in chronic hepatitis B treatment. Intra hepatic cccDNA disappearance reflects HBV eradication in the liver. Intra lymphocyte cccDNA could be a new marker of HBV eradication after treatment. The major interest of this marker is that it can be measured by a simple blood test instead of a liver biopsy.

\- Studying intra lymphocyte and blood cccDNA: before inclusions, D0 then each month during the first three months each three months during treatment and follow-up. \- Viral kinetics:Before inclusions, at D0, then monthly till the end of treatment and follow-up: Evolution of quantitative viraemia in serum Evolution of quantitative viraemia in circulating lymphocytes Evolution of quantitative viraemia in total blood \- Studying viral genotypes
