Introduction: Hepatitis B infection in pregnancy mandates careful monitoring and specialized management according to the phase of hepatitis B infection. Perinatal transmission may be prevented by antiviral therapy in mothers with high viral load and timely immunoprophylaxis of the infant.
Areas covered: This review focuses on the current first-line therapies for treating hepatitis B in pregnancy, timing of therapy, and prevention of perinatal transmission. Strategies to manage disease at the various phases and potential emerging therapies in phase III of development are also covered. Medline/PubMed and Cochrane databases were searched systematically from 1990 to April 2018 with the relevant articles selected for the review.
Expert opinion: Universal antenatal screening for hepatitis B and strict immunoprophylaxis for infants form the cornerstones to prevent hepatitis B virus (HBV) perinatal transmission. Tenofovir is the preferred drug for treatment in pregnancy in view of its good efficacy and high barrier to resistance. Most of the data on antivirals are from cohort studies which are prone to bias and more randomized controlled trials (RCTs) are needed to establish the benefits and safety of these drugs in pregnancy. Various novel drugs are in the pipeline which may pave the way for a cure in the near future.
