Abstract:
Objective:To investigate the prevalence of syphilis in HIV-infected patients with transmission risk and influencing factors in Zhejiang Province.Method:The information about the HIV-infected patients, who were alive, had been diagnosed with HIV for >1 year, had received no antiviral treatment or had HIV viral load ≥50 copies/ml, and were aged ≥15 years, reported in Zhejiang as of December 31, 2018 were collected from China Information System for Disease Control and Prevention. The information included general demographic characteristics, sexual behavior characteristics and antiretroviral therapy and syphilis serological test results. The prevalence of syphilis and the influencing factors were analyzed by logistic regression model. The SPSS 19.0 software was used for statistical analysis.Results:A total of 2 275 HIV-infected patients were at risk of HIV transmission, and 75.5% (1 717/2 275) of them were tested for syphilis, the prevalence rate of syphilis was 8.7% (150/1 717). Among the HIV-infected patients with syphilis, 11.3% (17/150) received no antiviral treatment, 38.7% (58/150) had viral load of 50-999 copies/ml and 50.0% (75/150) had ≥1 000 copies/ml. Multivariate logistic regression analysis showed that being men (a OR=2.04, 95% CI:1.06-3.96), homosexual transmission (a OR=1.53, 95% CI:1.04-2.27), history of sexually transmitted diseases (STDs) before HIV diagnosis (a OR=1.98, 95% CI:1.35-2.92) and HIV viral load ≥1 000 copies/ml (a OR=1.90, 95% CI:1.09-3.30) were the risk factors for syphilis. Marriage (a OR=0.47, 95% CI: 0.29-0.76) was a protective factor for syphilis. Conclusions:The prevalence of syphilis was high in HIV-infected patients with transmission risk in Zhejiang. It is urgent to carry out classified management and targeted intervention in HIV-infected patients, explore multi-disease prevention and treatment mechanism, strengthen syphilis screening and treatment in HIV-infected patients to reduce the transmission of HIV and syphilis.
