High Rates of Hepatitis B Virus (HBV) Functional Cure among Human Immunodeficiency Virus-HBV Coinfected Patients on Antiretroviral Therapy in Zambia

Academic Article


  • Among 284 human immunodeficiency virus (HIV)-hepatitis B virus (HBV) coinfected adults starting tenofovir-based antiretroviral therapy (ART) in Zambia, median baseline CD4+ count was 202 cells/mm3 and 41.6% were hepatitis B e-antigen positive. Within 2 years of therapy, 29 (10.2%) participants experienced HBV functional cure (confirmed loss of hepatitis B surface antigen). In multivariable analysis, baseline CD4 count <350 cells/mm3, female sex, and lower baseline HBV deoxyribonucleic acid were associated with increased odds of functional cure. Immune recovery during HIV-HBV treatment with ART may drive higher rates of functional cure than during HBV monoinfection treatment. Understanding the mechanisms underlying this phenomenon could inform immunomodulatory therapies for HBV cure.
