OBJECTIVE: To describe the characteristics of hepatitis B (HBV) infection in HIV-infected patients and the impact of anti-HBV treatments.
PATIENTS AND METHODS: All the patients with past or present chronic HBV infection seen in October 2005 in 17 French hospitals were included. Data were retrospectively collected from their first visit in a time-dependent manner, through a detailed standardized questionnaire.
RESULTS: Among 477 HBV-infected patients, 261 (55%) were co-infected with HIV. The HBV-HIV co-infected patients underwent fewer serological, virological and histological evaluations. Initial positive HBe antigenemia (HBe Ag) was more frequent in these patients (57.9 versus 28.6%; P < 10), as was cirrhosis on the initial liver biopsy (17.9 versus 7.6%; P = 0.05). Throughout the mean 5-year follow-up, HBe Ag loss was less frequent (P = 0.04), as was HBe seroconversion (incidence rate 2.6 versus 10/100 patient-years; P < 10). HBe Ag loss was associated with fibrosis improvement (METAVIR score -0.5 +/- 0.4 versus +0.2 +/- 0.6 if persistent positive HBe Ag, P = 0.01). In co-infected patients on tenofovir, adefovir or interferon, HBe seroconversions were seen in patients on combined HBV treatment, the use of which is increasing (58% in 2005). Nevertheless, no significant difference in virological, immunological or biochemical evolution was observed between these different treatments.
CONCLUSIONS: In HBV-HIV co-infected patients, the assessment of HBV infection still needs to be improved, the HBV wild-type remains predominant, and HBe Ag loss is rare and associated with a better histological evolution. There is insufficient evidence of the superiority of combined HBV treatment, and this still needs be demonstrated in long term studies.https://www.ncbi.nlm.nih.gov/pubmed/17545709
