Management and treatment of chronic hepatitis B virus infection in HIV positive and negative patients: The EPIB 2008 study

To compare the management and the virological and serological efficacy of treatments for chronic hepatitis B (CHB) in HIV positive and negative patients.Two hundred and forty-six HIV positive and 205 HIV negative consecutive patients with past or present CHB, seen in October 2008 in participating departments, were included in a multicenter study. All the data were retrospectively collected from the first visit to October 2008 through a standardized questionnaire.Compared to HIV negative patients, HIV positive patients more often presented positive HBeAg (46.4% vs. 32.8%, p=0.01), HBV genotype A (54.8% vs. 17.1%, p0.0001), co-infection with HCV (12.4% vs. 5.9%, p=0.0002) or HDV (12.6% vs. 2.9%, p=0.04). HIV positive patients were more often on HBV therapy (92.7% vs. 57.1%, p0.0001), leading to undetectable serum HBV DNA levels (71.0% vs. 44.1%, p0.0001). In HIV positive patients, multivariate analysis showed that older age, lower initial HBV DNA levels, and longer time on HBV therapy significantly correlated with undetectable HBV DNA. No difference in efficacy was observed between tenofovir used alone or in combination. HBsAg (but not HBe) loss was more often observed in HIV positive patients, sometimes followed by HBsAg re-appearance after withdrawal of HBV treatment. Excluding the 37 HBV-HCV-co-infected patients, the last clinical presentation and liver fibrosis scores were similar in HIV positive and negative patients.The assessment of CHB and the efficacy of HBV therapy have improved in HIV positive patients. HIV infection did not have a negative impact on the likelihood of HBV therapeutic success.
