High prevalence of syphilis, HBV, and HCV co-infection, and low rate of effective vaccination against hepatitis B in HIV-infected patients in West China hospital.

To investigate the epidemiological features and risk factors of HBV, HCV, and syphilis infection among HIV-infected patients in West China Hospital. A retrospective study was conducted with HIV-infected patients from 2014 to 2016 in West China hospital, SCU. Serum makers for HBV, HCV, and syphilis were detected. Among 894 HIV-infected patients, the prevalence of HIV/HBV, HIV/HCV, HIV/syphilis co-infections was 14.4%, 5.7%, and 18.9% respectively. HIV/HBV/HCV, HIV/HCV/syphilis, and HIV/HBV/syphilis triple co-infection was 7 (0.7%), 12(1.3%), 29(3.2%) respectively. The rate of effective vaccination against HBV was only 7.7% in HIV-infected patients. Age (OR = 0.243 95% CI: 0.114 -0.518), ethnicity (OR = 3.654 95% CI: 1.849-7.218) and education level (OR = 0.140 95% CI: 0.033-0.606) are risk factors affecting HIV/HCV co-infection. A high prevalence of HIV/syphilis, HIV/HBV, and HIV/ HCV co-infection can be observed in west China. The rate for HIV-infected patients who were effectively vaccinated against HBV was fewer than 10%.
