and Aim: Hepatitis Delta Virus (HDV) infection has been mainly studied in HIV negative patients, while data on HIV-1 positive patients are limited. We investigated the virological pattern as well as biochemical and clinical features of liver disease and immune status in HIV-1 positive patients with delta hepatitis. Their clinical characteristics were compared with those of anti-HDV negative, hepatitis B surface antigen (HBsAg) positive/HIV+ patients. Methods: This retrospective study included

Potential determinants for HDV positivity were examined by applying multivariate regression model. Results: Of 78 HBsAg positive patients 19 (24.4%) were found anti-HDV+. Anti-HDV+ patients were more frequently intra venous drug users, anti-HCV positive and HBV e antigen (HBeAg) negative. Additionally, the patients had more severe liver disease and necro inflammatory activity (assessed by transient elastography and transaminases levels, repectively) than the counterpart of anti-HDV-patients. A suppressive effect of HDV over HCV was also revealed in anti-HDV+ subjects. By multivariate analysis, years of ART (OR 1.22; CI 0.986-1.43, p=0.014) and sexual exposure vs. IVDU (OR 0.08; CI 0.556-0.986, p=0.004) were independently associated with anti-HDV positivity. Conclusion: Our data underlines the need for continuing prevention program that includes HBV vaccination, screening and monitoring in population at high risk, as well as development of an alternative treatment option for HDV.
