CXCL9 associated with sustained virological response in chronic hepatitis B patients receiving peginterferon alfa-2a therapy: a pilot study.

ABSTRACT:

Background and aims

There is lack of a practical biomarker to predict sustained virological response (SVR) in chronic hepatitis B (CHB) patients undergoing peginterferon alfa-2a (PEG-IFN). The aim of this pilot study was to identify immunological features associated with SVR.

Methods

Consecutive 74 CHB patients receiving 24 weeks (for hepatitis B e antigen (HBeAg)-positive) or 48 weeks (for HBeAg-negative) PEG-IFN, were prospectively enrolled. Serum HBV viral loads, hepatitis B surface antigen (HBsAg), CXCL9, IFN-γ-inducible protein 10 (IP-10), interferon-gamma (IFN-γ) and transforming growth factor beta (TGF-β) were measured at baseline and week 12. SVR was defined as HBeAg seroconversion combined with viral load <2000 IU/mL in HBeAg-positive (n=36), and viral load <2000 IU
