Abstract:
Objective:To understand the survival status of AIDS patients after initiation of antiretroviral treatment (ART) in Shandong province during 2003 to 2017, and to determine the factors associated with survival status.
Methods:A retrospective cohort study was conducted among AIDS patients initially received antiretroviral therapy from 2003 to 2017. The epidemiological characteristics of the subjects were described, and life tables were used to estimate the survival rates, the influencing factors were analyzed by Cox regression model.
Results:A total of 9 813 cases were enrolled in this study, of the subjects, the median age was 34.9±11.0 years. The median of baseline CD4+ T lymphocyte count was 300.0(P25-P75: 163.0, 428.0)cells/μl, and 83.2% of them were at clinical stage Ⅰ (World Health Organization, WHO). The cumulative survival rates were 97.7%, 96.7%, 95.8% and 93.7%, 1, 3, 5, and 10 years after the initiation of ART respectively. Multivariate Cox regression model analysis showed that the risk of the mortality among those infected through homosexual behavior was 38% lower than that of patients infected via blood or other routes, and HR was 0.62 (95%CI: 0.43-0.89). Higher education level had lower mortality risk(the mortality risk of those with university degree or above was lower, compared to those with primary and lower cultural level, HR=0.41, 95%CI: 0.26-0.65). At baseline, AIDS patients at clinical stage Ⅰ(WHO) had lower mortality risk than those who were at clinical stageⅡ, Ⅲ, and Ⅳ(WHO). Lower baseline CD4+ T lymphocyte count had higher mortality risk.
Conclusions:Survival rate was higher after initial antiretroviral therapy among AIDS patients in Shandong province. CD4+ T lymphocyte count level, WHO clinical stage, and presence or absence of clinical symptoms at baseline are the main factors influencing the survival time of AIDS patients after ART.
