We investigated the decline of hepatitis B virus surface antigen (HBsAg) and core related antigen (HBcrAg) in chronic hepatitis B patients sussessfully treated with nucleos(t)ide analogues. In patients with plasma viral suppression, the baseline median levels of HBsAg and HBcrAg were 3.1 and 3.0 log U/mL, respectively. The levels in naïve patients were 4.2 and 3.6 log U/mL for HBsAg and HBcrAg, respectively. No significant decline was observed in patients with viral suppression within a year period. A low reduction was observed during the first months after treatment initiation, especially regarding HBcrAg. The dynamics of these antigens after viral suppression should be further investigated.
Keywords: HBV; HBcrAg; HBsAg; chronic hepatitis; nucleos(t)ide analogues.
