Does Treatment of Hepatitis B virus (HBV) Infection Reduce Hepatitis Delta virus (HDV) Replication in HIV-HBV-HDV-Coinfected Patients?

Abstract

Patients undergoing successful anti-HBV therapy with potent nucleos(t)ide analogues seem to indirectly benefit from suppression of HDV replication, albeit not very efficiently. Hypothetically, a significant and sustained reduction in serum HDV RNA might only be seen when a reduction in HBV covalently closed circular DNA or HBV surface antigen is achieved, which may require long periods of successful anti-HBV therapy. To our knowledge, this is the first evidence of the benefit of potent anti-HBV nucleos(t)ide analogue therapy in CDH.
