Abstract

Background/purpose: This multicenter study aimed to evaluate the seroprevalence of hepatitis B virus (HBV) and the use of combination antiretroviral therapy (cART) among patients receiving HIV care in Taiwan. Methods: We retrospectively reviewed the medical records of HIV-infected adult patients who initiated cART at 11 designated hospitals in Taiwan between 2012 and 2016. The clinical information collected included serological profiles on HBV, hepatitis C virus (HCV), and syphilis, plasma HIV RNA load, nadir CD4 cell count, and antiretrovirals with activity against both HBV and HIV (tenofovir disoproxil fumarate [TDF], lamivudine [LAM], and emtricitabine [FTC]). Results: We analyzed 1800 HIV-infected patients; 1742 (96.8%) were male and 794 (44.1%) were born after July, 1986, when nationwide universal neonatal HBV vaccination was implemented. HBsAg positive results were 11.6% (209/1800), which decreased significantly from 18.1% (182/1006) in those born before July 1986 to 3.4% (27/794) in those born after. In multivariable analysis, HBsAg positivity was significantly associated with age (adjusted odds ratio [aOR] 1.06, 95% confidence interval [CI] 1.05–1.08), CD4≧200 cells/μL (aOR 0.73, 95% CI 0.53–0.99), and HCV seropositivity (aOR 1.62, 95% CI 1.06–2.50). Of 209 HBV/HIV-coinfected patients, 31.1% started cART containing only LAM with anti-HBV activity, while 68.9% started cART containing TDF plus LAM or coformulated TDF/FTC. Conclusions: The overall prevalence of HBV/HIV coinfection remained high among HIV-infected patients in Taiwan. Despite recommendations of the HIV treatment guidelines for the management of HBV infection, a substantial proportion of HIV/HBV-coinfected patients received cART containing only LAM for HBV infection.
