This digitally colorized transmission electron micrograph reveals the presence of hepatitis B virions. The large round virions are known as Dane particles.
The recommendation statement, published in JAMA, was based on an evidence report and systematic review also published in JAMA. In that review, two studies of fair quality were identified; one included 155,081 infants born to HBV-positive women identified for case management through the national Perinatal Hepatitis B Prevention Program from 1994 to 2008, and the other included 4,446 infants born in a large, regional health care organization in the United States between 1997 and 2010. In both, low rates of perinatal transmission were reported for those periods – between 0.5% and 1.9% – with the rate falling over time.
In the 2009 recommendation, the USPSTF found adequate evidence that serologic testing for hepatitis B surface antigen accurately identifies HBV infection, and that interventions were effective in preventing perinatal transmission. That recommendation has been reaffirmed in the current update, with HBV screening receiving a grade of A, which is the strongest the USPSTF offers.
In a related editorial, Neil S. Silverman, MD, of the Center for Fetal Medicine and Women’s Ultrasound in Los Angeles noted several improvements in maternal HBV therapy since the publication of the original 2009 recommendation, including maternal HBV-targeted antiviral therapy during pregnancy as an adjunct to neonatal immunoprophylaxis and the ability to refer women for chronic treatment of their HBV disease to prevent long-term infection complications. The task forces also noted that HBV screening of all pregnant women is mandated by law in 26 states.
One member of the task force reported receiving grants and/or personal fees from Healthwise, another member reported receiving personal fees from UpToDate; a third reported participating in the American Association for the Study of Liver Diseases’ Hepatitis B Guidance and Hepatitis B Systematic Review Group. The evidence and review study was funded by the Agency for Healthcare Research and Quality. Dr. Silverman reported no disclosures.
