Abstract:

Objective To understand the survival status and the influencing factors in patients infected with human immunodeficiency virus (HIV) /acquired immune deficiency syndrome (AIDS) in Hefei area for theoretical basis in formulating intervention measures. Methods The routine data, follow-up data and treatment status of HIV/AIDS victims in Hefei area were retrieved from 1997 to 2023 via the National Comprehensive HIV/AIDS Information Management System. The survival rate of HIV/AIDS sufferers was calculated by life table method, and the average survival time was estimated by Kaplan-Meier plotter. Cox regression model was used to analyze the factors affecting the survival in HIV/AIDs victims and those receiving antiretroviral therapy. Results A total of 4 305 patients infected with HIV/AIDS were reported in Hefei area from 1997 to 2023, in which there were 371 deaths. The all-cause mortality rate was 1.56/100 person-years, and the average survival time was 18.89 years. The average survival time was significantly longer in patients who received antiretroviral therapy than in the untreated patients (19.63 years versus 3.49 years, χ2=2 304.81, P<0.01). Multivariate Cox regression analysis showed that lower age [15-24 years (HR=0.20), 25-34 years (HR=0.36), 35-44 years (HR=0.47)] was a protective factor for the survival of HIV/AIDS victims. Being unmarried (HR=1.52), divorced or widowed (HR=1.33), primary school or below (HR=2.11), junior high school (HR=1.53), high school or technical secondary school (HR=1.54), heterosexually transmitted infection (HR=1.30), lower first CD4+ T lymphocyte count [0-49 (HR=5.32), 50-199 (HR=2.62) and 200-349 (HR=2.43)] and absence of antiretroviral therapy (HR=29.61) were risk factors for the survival. In addition, lower age [15-24 years (HR=0.12), 25-34 years (HR=0.21) and 35-44 years (HR=0.36)] was a protective factor for death in patients undergone antiretroviral therapy. BMI<18.5 kg/m2 before treatment (HR=2.22), unmarried (HR=2.76), divorced or widowed (HR=1.91), primary school or below (HR=3.02), junior high school (HR=1.95), heterosexually transmitted infection (HR=1.46), lower CD4+T lymphocyte count at initial measurement [0-49 (HR=2.91) and 50-199 (HR=2.03)], clinical stage Ⅳ by WHO before treatment (HR=1.75), and initial second-line treatment plan (HR=1.56) were risk factors for the death in patients who received antiretroviral therapy. Conclusion Antiretroviral therapy is a key factor affecting the survival time of infected with HIV/AIDS victims. Age at diagnosis, BMI before treatment and CD4+T lymphocyte count at the first laboratory test are the main factors affecting death in patients who had received treatment. Early detection, diagnosis and treatment can reduce the risk of death in the HIV/AIDS victims.
