Impact of Highly Active Antiretroviral Therapy on Chronic Hepatitis B Serological Markers among Senegalese HIV Co-infected Children.

ABSTRACT: Background:Coinfection with human immunodeficiency virus (HIV) and hepatitis B virus (HBV) causes complex interactions. The aim of this study was to evaluate the seroprevalence and HBV evolution among HIV coinfected children receiving highly active antiretroviral therapy (HAART). Methods:A descriptive cross-sectional study was carried out among 252 HIV infected children enrolled in the Hôpital d'enfants Albert Royer, Dakar, Senegal, from April 2013 to March 2015. Clinical characteristics, immuno-virological status, alanine aminotransferase (ALT) levels, and HBV serological marker were taken from the patients' medical records. Results:Overall, 7 children were HBsAg positive with a determinate prevalence rate of 2.8%. Median age at HIV diagnosis was 3.5 years (1.3-14.4 years). According to World Health Organization (WHO) staging, 40.1% of children were stage 4 and 25.8% were stage 3. Of the 7 HIV/HBV-co-infected children, 6 (86%) received lamivudine alone at initiation of treatment, and only one child received tenofovir associated with emtricitabine. Overall median HAART duration treatment including lamivudine alone or tenofovir+lamivudine (or emtricitabine) was 7.7 years (3.3-11.3). Only the two children (29%) receiving lamivudine during follow-up had high HBV DNA load despite having good immuno-virological status. Suppression of HBV DNA replication was achieved in 5 (71.4%) of 7 children. Conclusion and Global Health Implication:HIV/HBV coinfection prevalence was low in our study. HBsAg and HBeAg loss were low while suppression of HBV DNA replication was still higher on tenofovir. Screening and monitoring HBV infection among all HIV infected children are required to direct treatment in order to improve children HBV/HIV coinfected outcome.

Project description:BackgroundApproximately 4 million of people are co-infected with HIV and Hepatitis B virus (HBV). In resource-limited settings, the majority of HIV-infected patients initiate first-line highly active antiretroviral therapy containing lamivudine (3TC-containing-HAART) and long-term virological response of HBV to lamivudine-containing HAART in co-infected patients is not well known.Methodology/principal findingHIV-HBV co-infected patients enrolled in the PHPT cohort (ClinicalTrials.gov NCT00433030) and initiating a 3TC-containing-HAART regimen were included. HBV-DNA, HIV-RNA, CD4+ T-cell counts and alanine transaminase were measured at baseline, 3 months, 12 months and then every 6 months up to 5 years. Kaplan-Meier analysis was used to estimate the cumulative rates of patients who achieved and maintained HBV-DNA suppression. Of 30 co-infected patients, 19 were positive for HBe antigen (HBeAg). At initiation of 3TC-containing-HAART, median HBV DNA and HIV RNA levels were 7.35 log(10) IU/mL and 4.47 log(10) copies/mL, respectively. At 12 months, 67% of patients achieved HBV DNA suppression: 100% of HBeAg-negative patients and 47% of HBeAg-positive. Seventy-three percent of patients had HIV RNA below 50 copies/mL. The cumulative rates of maintained HBV-DNA suppression among the 23 patients who achieved HBV-DNA suppression were 91%, 87%, and 80% at 1, 2, and 4 years respectively. Of 17 patients who maintained HBV-DNA suppression while still on 3TC, 4 (24%) lost HBsAg and 7 of 8 (88%) HBeAg-positive patients lost HBeAg at their last visit (median duration, 59 months). HBV breakthrough was observed only in HBeAg-positive patients and 6 of 7 patients presenting HBV breakthrough had the rtM204I/V mutations associated with 3TC resistance along with rtL180M and/or rtV173L.ConclusionsAll HBeAg-negative patients and 63% of HBeAg-positive HIV-HBV co-infected patients achieved long-term HBV DNA suppression while on 3TC-containing-HAART. This study provides information useful for the management of co-infected patients in resource-limited countries where the vast majority of co-infected patients are currently receiving 3TC.
