Chronic Hepatitis B

Brief summary
Treatment with a nucleoside analogue and subsequent viral decline has shown to partially restore immune hyporesponsiveness in chronic hepatitis B patients. Recent pilot studies investigating whether the effect of lowering viral load with nucleoside analogue therapy prior to the initiation of peginterferon results in higher sustained off-treatment responses showed contradictory findings. The aim of this study is to investigate sustained off-treatment response to peginterferon alfa-2b in chronic HBeAg-positive hepatitis B patients who are pretreated with nucleos(t)ide analogues, thereby lowering viral load
Interventions
