The appropriate prophylaxis for hepatitis B virus reactivation (HBVr) during gestation for immunocompromised pregnant women has yet to be determined. The prophylactic efficacy and safety of tenofovir disoproxil fumarate (TDF) in hepatitis B surface antigen (HBsAg)-positive patients and the HBVr risk in hepatitis B core antibody (HBcAb)-positive patients during gestation were investigated. Eligible pregnant women were diagnosed with rheumatic diseases and were administered prednisone (≤10 mg daily) with permitted immunosuppressants at screening. HBsAg-positive participants were instructed to take TDF; those unwilling to take TDF were followed up as the control group. Propensity score matching was applied to control for differences in confounding factors between the HBcAb-positive and uninfected groups. Hepatopathy, maternal, pregnancy, and safety outcomes were documented as endpoints. A cohort of 1292 women was recruited from 2017 to 2020, including 58 HBsAg-positive patients (29 in each group). A total of 120 pairs in the HBcAb-positive and noninfection groups were analyzed. Among HBsAg-positive patients, 6 (20.7%) cases of hepatitis flare (hazard ratio [HR]: 7.44; 95% confidence interval [CI]: 1.50-36.89; p = 0.014) and 12 (41.4%) cases of HBVr (HR: 8.71; 95% CI: 2.80-27.17; p < 0.001) occurred in the control group, while 0 occurred in the TDF prophylaxis group. The HBV level at delivery was the lowest (1.6 log 10 IU/ml) for those who received TDF during the pregestation period with a good safety profile. More adverse maternal outcomes were observed in the control group (odds ratio: 0.19, 95% CI: 0.05-0.77, p = 0.021), including one death from fulminant hepatitis and two cases of vertical transmission. No HBVr was recorded in HBcAb-positive participants. Among immunocompromised pregnant women, prophylactic TDF during pregestation was necessary for HBsAg-positive women, whereas regular monitoring was recommended for HBcAb-positive women.
