Recurrence risk factors for chronic hepatitis B virus-infected patients who achieve functional cure with pegylated interferon-α-2b-based therapy: a multicenter pilot study.

ABSTRACT:

Background

Hepatitis B surface antigen (HBsAg) clearance is an achievable treatment endpoint for chronic hepatitis B virus (HBV)-infected patients. Pegylated interferon-α (PEG-IFN-α) induces higher rate of HBsAg clearance than nucleos(t)ide analogues. However, the influencing factors associated with HBsAg recurrence have not been fully elucidated. The aim of this study was to evaluate the risk factors for recurrence in chronic HBV-infected patients who achieved functional cure with PEG-IFN-α-2b-based treatment.

Methods

A multicenter retrospective study was conducted. All patients received PEG-IFN-α-2b-based therapy, achieved HBV DNA negativity and HBsAg clearance, and were followed-up for at least 48 weeks after discontinuation of medications. The demographic data, as well a
