    Abstract:
    OBJECTIVE: Detection of hepatitis B virus (HBV) DNA without detectable hepatitis B surfaceantigen (HBsAg) is defined as occult HBV infection. In patients co-infected with human immunodeficiency virus (HIV) and HBV, HIV interferes with the natural history of HBV infection by enhancing HBV replication, leading to more severe liver disease. The aim of this study was to assess occult HBV infection in Iranian HIV-positive patients with isolated hepatitis B core antibody (anti-HBc). METHODS: The presence of HBV-DNA was determined quantitatively in plasma samples of HIV-infected patients with isolated anti-HBc by real-time PCR using the artus HBV RG PCR kit on the Rotor-Gene 3000 real-time thermal cycler. Hepatitis C antibody (anti-HCV), alanine aminotransferase (ALT), aspartate aminotransferase (AST), HIV viral load and CD4+ count were also tested in all subjects. RESULTS: Of 106 patients enrolled in this study, 22 subjects (20.75%, 95% CI 13-28) had isolated anti-HBc. HBV-DNA was detectable in 3 of the 22 patients (13.6%, 95% CI 0.0-28) who had isolated anti-HBc. CONCLUSION: A serological profile of isolated anti-HBc could be associated with occult HBV infection in Iranian HIV-infected patients. Therefore the risk of transmission of HBV is probable in these patients.
