ABSTRACT
We used HBV core antigen (HbcrAg), pre-genomic RNA (pg RNA) and other biomarkers to evaluate the therapeutic effect in HBV infected patients receiving anti-viral therapy. 127HBeAg-positive patients were enrolled 35 patients received nucleotide therapy, 14 patients received interferon and 78 patients received combination therapy with both. HBcrAg, pg RNA and other biomarkers were detected at different time points, we defined the decreased titre of HBcrAg and HBeAg from baseline to 6 and baseline to 12 months as ∆HBcrAg and ∆HBeAg, which were used to predict HBeAg seroconversion. Furthermore, we used the time-dependent receiver operator curve of different markers to analyse HBeAg seroconversion. For HBeAg seroconversion at 6 months, 0.75 log10 U/mL of ∆HBcrAg and 1.47 log10 PEI U/mL of ∆HBeAg showed maximum predictive value in receiver operator curve analysis (Youden's index values for area under the curve of 0.687 and 0.646, respectively). At 12 months, 2.05 log10 U/mL of ∆HBcrAg and 1.92 log10 PEI U/mL of ∆HBeAg showed improved prediction (maximum Youden's index values, with areas under the curve of 0.688 and 0.698, respectively).pg RNA was a better predictor of outcome due and the concentrations of 6.20 log10 I U/mL of pg RNA and 8.0 log10 U/mL of HBcrAg were cut-off values for response in a Kaplan-Meier curve analysis. Our results may be used to identify the pg RNA concentration in patients at baseline and ∆HBcrAg during therapy who are likely to achieve HBeAg seroconversion according to the cut-off value at different time points, thus helping to evaluate the therapeutic effect.
