Abstract
Infection with hepatitis delta virus (HDV) affects approximately 6-14.5% of patients coinfected with HIV-1 and HBV, showing a more aggressive clinical course compared with an HIV-negative population. There is no universally approved treatment for chronic hepatitis D (CHD) in HIV-infected patients. Antiretroviral therapy (ART) containing tenofovir has been recently associated with HDV suppression. Our aim was to evaluate whether the outcome of CHD in HIV-infected patients can be favourably influenced by ART including reverse transcriptase inhibitors. The clinical course of four HBV/HDV/HIV-coinfected patients receiving ART were retrospectively examined. HDV RNA became undetectable in all patients after a variable period of ART along with the disappearance of hepatitis B surface antigen in two of them, and an increase in CD4(+) T-cell count. In all patients, virological changes were associated with improved liver function tests and clinical features. We suggest that ART regimens including drugs active against HBV could have beneficial effects on the clinical course of CHD in patients with HIV-1 by favouring immunological reconstitution.
