Abstract
Reliable predictors of outcomes after treatment discontinuation in HBeAg-negative chronic hepatitis B (CHB) patients have not been established. We investigated the role of hepatitis B surface antigen (HBsAg), interferon-inducible protein-10 (IP10) and hepatitis B core-related antigen (HBcrAg) serum levels as predictors of HBsAg loss, relapse and retreatment in noncirrhotic HBeAg-negative CHB patients who discontinued long-term antiviral therapy. All HBsAg-positive (n = 57) patients of the prospective DARING-B study were included and followed monthly for 3 months, every 2/3 months until month-12 and every 3/6 months thereafter. HBsAg, IP10 and HBcrAg levels were measured by enzyme immunoassays, and SCALE-B score was calculated. Twelve patients achieved HBsAg loss before retreatment with 18-month cumulative incidence of 25%. Independent predictors of HBsAg loss were baseline HBsAg and month-1 IP10 levels. Of 10 patients with baseline HBsAg ≤100 IU/mL, 70% cleared HBsAg and 10% required retreatment. Of 23 patients with baseline HBsAg >1000 IU/mL, 4% cleared HBsAg and 43% required retreatment. Of 24 patients with intermediate baseline HBsAg (100-1000 IU/mL), 17% cleared HBsAg and 21% required retreatment; in this subgroup, month-1 IP10 was significantly associated with HBsAg loss, which occurred in 30% and 7% of cases with IP10 >150 and ≤150 pg/mL, respectively. Baseline HBcrAg was undetectable in all patients who cleared HBsAg and was associated with retreatment. SCALE-B was associated with HBsAg loss but not with relapse or retreatment. In conclusion, HBsAg, IP10 and HBcrAg serum levels can be useful for the decisions and management of treatment discontinuation in noncirrhotic Caucasian patients with HBeAg-negative CHB. © 2019 John Wiley & Sons Ltd
