GOALS: The study is to evaluate the efficacy and long-term safety of telbivudine (LdT) usage for hepatitis B surface antigen (HBsAg) positive pregnant women with high viral load.
BACKGROUND: The efficacy and safety of LdT during pregnancy were not assessed from a long-term perspective.
STUDY: HBsAg-positive pregnant women were enrolled and grouped according to antiviral initiation time. Group A (n=100) and group B (n=100) were treated with LdT initiated in the second or third trimester. Group C (n=90) received no antiviral treatment. The efficacy and safety of LdT treatment were compared and infants were followed-up at 1, 5, and 10 years. Denver developmental screening test was conducted at 5 years.
RESULTS: Viral loads before delivery in LdT-treated groups were lower than that in group C and group A was lower than that in group B ( P <0.001). No infants in LdT-treated groups were infected whereas 8.8% (8/90) infants in group C had positive HBsAg (χ 2 =23.20, P <0.001). All LdT-treated mothers were well tolerated and no LdT-related adverse events in infants were reported. Part of the physical growth index of infants was higher than Chinese standard values (SV) and showed significant differences. In groups A and B, the developmental screening test qualified rate of 100% (48/48) and 97.96% (48/49) showed no significant difference compared with 92% in normal Chinese children (χ 2 =5.72, P =0.06).
CONCLUSIONS: Treatment initiated during the second trimester could strengthen the success of mother-to-child transmission blockage. LdT treatment during pregnancy is safe for both mothers and infants in the long term.
