Predictors of inflammatory activity in treatment-naive hepatitis B e-antigen-negative patients with chronic hepatitis B infection.

Abstract

ObjectiveLiver inflammatory activity staging is critical to guide the treatment of chronic hepatitis B virus (CHB) infection. Here, we aimed to identify practical clinical biomarkers of moderate inflammatory activity in hepatitis B e-antigen (HBeAg)-negative CHB patients.MethodsTreatment-naïve HBeAg-negative CHB patients who underwent liver biopsy at our hospital from 1 January 2013 to 31 December 2016 were enrolled. Markers of inflammatory activity were analyzed using binary logistic regression. The area under the receiver operator characteristic curve (AUROCC) was used to assess diagnostic accuracy.ResultsA total of 106 HBeAg-negative treatment-naive CHB patients were enrolled. According to their METAVIR inflammatory scores, 30.2% of patients were in stage ≥A2. Total triiodothyronine (TT3) and hepatitis B virus (HBV) DNA levels were predictors of moderate inflammatory activity (A ≥ 2). The AUROCCs of TT3 and HBV DNA levels were 0.651 and 0.797, respectively. The optimal cut-off values for TT3 and HBV DNA were 1.755 nmol/L and 4.61 log10 IU/mL, respectively.ConclusionsA sizable proportion of treatment-naive HBeAg-negative CHB patients required antiviral treatment (30.2%) after undergoing liver biopsy. TT3 and HBV DNA helps identify patients with moderate inflammatory activity (A ≥ 2), potentially reducing the need for liver biopsies and helping guide treatment of CHB patients.
