Circulating HBV RNA and hepatitis B core-related antigen as determinants of HBsAg loss in persons with HIV in Europe.

ABSTRACT:

Background & aims

HBsAg loss improves clinical outcomes in persons with HIV and HBV coinfection. We aimed to evaluate if hepatitis B core-related antigen and circulating HBV RNA levels were associated with HBsAg loss in Euro-B, a multi-cohort collaboration including data from the Swiss HIV Cohort Study, EuroSIDA, and the French HIV/HBV cohort.

Methods

We included persons with HIV, a positive HBsAg, and ≥6 months of follow-up on tenofovir-containing antiretroviral therapy. We evaluated quantitative HBsAg, HBV DNA, hepatitis B core-related antigen, and HBV RNA levels over time and assessed HBsAg loss (i.e. quantitative HBsAg <0.05 IU/ml) during tenofovir therapy.
