On August 26, 2023, we summarized the ACOG update on viral hepatitis in pregnancy and discussed new concepts regarding Hep B viral infection. To follow that up, the SMFM has now released its Consult Series #69 (Hepatitis B in Pregnancy: Updated Guidelines) which was published on December 21, 2023. In this episode, we will reinforce some topics originally discussed back in August 2023 and emphasize key management issues regarding Hep B in pregnancy based on this Consult Series… both for the infected, and the non-infected/non-immune patient. Is antepartum fetal surveillance indicated in these patients? Is C-section a way to prevent perinatal transmission? What’s the viral load cut-off to begin antiviral medication? Is it safe to administer hepatitis B vaccine during pregnancy for those who need it? Listen in for details.
