Epidemiology and influencing factors of human immunodeficiency virus and hepatitis B virus co-infected patients in Beijing

Abstract

Objective: To analyze the epidemiological characteristics of human immunodeficiency virus (HIV) and hepatitis B virus (HBV) co-infected patients in Beijing and investigate the associated factors. Methods: The clinical data of patients with HIV infection who were treated in HIV/AIDS designated hospitals (Peking Union Medical College Hospital, Beijing Ditan Hospital and Beijing Youan Hospital) were retrospectively analyzed. Results: A total of 11 572 patients were finally included in the study, among whom 532 patients (4.6%) were co-infected with HIV and HBV. Most of the co-infected patients were young male adults (28~48 years old), accounting for 85.9%. The main transmission route was homosexual behavior (74.8%). There were 87.4% co-infected patients treated with two anti-HBV drugs, including lamivudine (3TC) and tenofovir (TDF). From 2013 to 2018, the annual prevalence of HIV and HBV co-infection decreased gradually, with the rate of 6.37%, 4.55%, 3.92%, 4.68%, 4.24% and 2.74%, respectively. In our study, The main influencing factors of HIV and HBV co-infection were age older than 28 years old versus<28 years old (OR=2.807, 95%CI 1.241-6.345) and marriage status (married versus unmarried, OR=1.259, 95%CI 1.004-1.579). Conclusions: The proportion of HBV infection in HIV-infected patients is 4.60% (532) in our cohort. From 2013 to 2018, the prevalence of HIV and HBV co-infection in Beijing shows a decreasing trend. The risk of co-infection is higher in married young adults (28~48 years old).
