Exploring durability of hepatitis B surface antigen seroclearance using real-world data from electronic health records


In a study published in the journal Genes & Diseases, researchers from The Second Affiliated Hospital of Chongqing Medical University analyzed data from an extensive dataset comprising over 70,000 HBsAg-positive individuals at The Second Affiliated Hospital of Chongqing Medical University.

They compared two groups: those achieving HBsAg seroclearance through NAs monotherapy (168 patients) and those through IFN monotherapy (30 patients). NAs monotherapy patients were older, with a higher proportion achieving HBsAg seroclearance during treatment (48.8% vs. 30.0%). They also had a more favorable immune response, with a higher percentage developing concomitant anti-HBs.
