Abstract :
[en] 1. Introduction
Chronic hepatitis B virus (HBV) infection currently affects about 400 million people and is responsible for 500,000 to 1,000,000 deaths annually worldwide from cirrhosis and hepatocellular carcinoma (HCC) (1). For this reason, screening high risk populations to identify HBV infected persons is important so that guidelines for treatment and prevention of transmission can be given in this specific group. Recently, new drugs became available for HBV and new insights in resistance and definitions came up. So, the purpose of this paper is providing an update of the
recent literature and guidelines concerning 1. screening for chronic hepatitis B (CHB) 2. management of patients with CHB 3. treatment of CHB in mono-infected patients and in special patient populations (co-infected, transplanted and immunosuppressed patients). The recommendations are based onpublished information and the level of evidence is reported with each recommendation. The level of evidence is graded as :grade 1 : randomized controlled trials ; grade II-1 : controlled trials without randomization ; grade 11-2 : cohort or case-control analytic study ; grade 11-3 : multiple time series, dramatic uncontrolled experiments ; grade III :
descriptive epidemiology, expert opinions.
