Abstract

Hepatitis B virus (HBV) contains three viral surface proteins, large, middle and small hepatitis B surface protein (LHBs, MHBs, SHBs). Proportions of LHBs and MHBs are lower in patients with inactive versus active chronic infection. Interferon alfa may convert HBeAg-positive chronic hepatitis B (CHB) to an inactive carrier state, but prediction of sustained response is unsatisfactory. The aim of this study was to test the hypothesis that quantification of MHBs and LHBs may allow for a better prognosis of therapeutic response than total hepatitis B surface antigen (HBsAg) concentration. HBs proteins were measured before and during peginterferon alfa-2a therapy in serum from 127 Asian patients with HBeAg-positive CHB. Sustained response was defined as hepatitis B e antigen (HBeAg) seroconversion 24 weeks post-treatment. Mean total HBs levels were significantly lower in responders versus nonresponders at all time points (P<.05) and decreased steadily during the initial 24 weeks' treatment (by 1.16 versus 0.86 ng/mL in responders/nonresponders, respectively) with unchanged relative proportions. Genotype B had a twofold higher proportion of LHBs than genotype C (13% versus 6%). HBV DNA, HBeAg, HBsAg, and HBs protein levels predicted response equally well but not optimally (area under the ROC curve values >0.70). HBs proteins levels differ by HBV genotype. However, quantification of HBs proteins has no advantage over the already established HBsAg assays to predict response to peginterferon alfa-2a therapy in HBeAg-positive patients. © 2019 John Wiley & Sons A/S.
