Early hepatitis B surface antigen decline predicts treatment response to entecavir in patients with chronic hepatitis B.

ABSTRACT: Early declines in serum hepatitis B surface (HBsAg) levels, their optimal cutoffs, and association with therapeutic endpoints in chronic hepatitis B (CHB) patients receiving entecavir treatment remain unclear. We prospectively enrolled 529 patients (195 hepatitis B e antigen [HBeAg]-positive and 334 HBeAg-negative) with a median treatment duration of 49.2 months. Median HBsAg levels declined significantly in both groups at Month 3, but only at Months 6-12 in the HBeAg-negative group. Both groups exhibited a significant HBsAg decline with each successive year of treatment. An HBsAg decline of ≥75% from baseline, assessed at Months 3 and 12 of treatment in the HBeAg-positive and -negative patients, respectively, independently predicted a virological response and HBeAg seroconversion in the H
