Abstract

BACKGROUND:

Hepatitis B (HBV)-HIV coinfection is associated with liver inflammation, which can progress to liver fibrosis/cirrhosis and hepatocellular carcinoma. We determined HBV seroprevalence in children and adolescents participating in the TREAT Asia Pediatric HIV Observational Database.

METHODS:
A multi-site cross-sectional study was conducted in HIV-infected patients currently aged <25 years receiving antiretroviral treatment (ART) who had HBV surface antigen (HBsAg), and/or HBV surface antibody (anti-HBs), and/or HBV core antibody (anti-HBc) tested during 2012-2013. HBV coinfection was defined as having either a positive HBsAg test, or being anti-HBc positive and anti-HBs negative, reflective of past HBV infection. HBV seroprotection was defined as having a positive anti-HBs test.

RESULTS:
A total of 3,380 patients from six countries (Vietnam, Thailand, Cambodia, Malaysia, Indonesia, India) were included. The current median (interquartile range; IQR) age was 11.2 (7.8-15.1) years. Of the 2,755 (81.5%) patients with HBsAg testing, 130 (4.7%) were positive. Of 1,558 (46%) with anti-HBc testing, 77 (4.9%) were positive. Thirteen of 1,037 patients with all three tests were anti-HBc positive and HBsAg and anti-HBs negative. One child was positive for anti-HBc and negative for anti-HBs, but did not have HBsAg tested. The prevalence of HBV coinfection was 144/2,759 (5.2%) [95% confidence interval 4.4-6.1]. Of 1,093 (32%) patients with anti-HBs testing, 257 (23.5; CI 21.0-26.0) had positive tests representing HBV seroprotection.

CONCLUSIONS:
The estimated prevalence of HBV coinfection in this cohort of Asian HIV-infected children and adolescents on ART was 5.2%. The majority of children and adolescents tested in this cohort (76.5%) did not have protective HBV antibody. The finding supports HBV screening of HIV-infected children and adolescents to guide revaccination, the use of ART with anti-HBV activity, and future monitoring.
