Abstract
Background/purpose
The study compared the hepatitis B surface antigen (HBsAg) changes between hepatitis B e antigen (HBeAg)-negative non-cirrhotic chronic hepatitis B patients who discontinued or maintained entecavir therapy.
Methods
A total of 250 HBeAg-negative, non-cirrhotic patients who were treated with entecavir previously and had stopped treatment for at least 12 months (discontinued group) and 231 HBeAg-negative, non-cirrhotic patients who had received entecavir treatment for at least 4 years (maintained group) were recruited.
Results
In the discontinued group, 71 had a persistent virological suppression (Group I), 35 experienced virological relapse but no clinical relapse or retreatment (Group II), 26 experienced clinical relapse without retreatment (Group III), and 118 experienced HBV relapse and retreatment (Group IV). Patients in Groups I, II, and III, but not in Group IV, experienced a significantly larger drop in HBsAg levels’ post-treatment than during entecavir treatment. Patients in Groups I and III exhibited a greater post-treatment HBsAg decline than patients in Groups II and IV (p < 0.001). Discontinued group experienced a significantly larger drop in HBsAg levels (p < 0.001) and higher HBsAg loss rate (p = 0.001) than maintained group after adjusting for clinical features and HBsAg levels in propensity score matched patients. Patients in maintained group exhibited a smaller drop in HBsAg and lower HBsAg loss rate than patients in groups I, II, and III, but not in Group IV.
Conclusions
Patients who discontinued entecavir therapy and achieved persistent virological suppression exhibited a greater HBsAg decline and higher HBsAg loss rate compared with patients who maintained entecavir therapy.作者: StephenW 时间: 2020-5-18 17:48
