Survival analysis of patients receiving antiretroviral treatment in integrated HIV/AIDS prevention and treatment demonstration zone of Chongqing,China,2016-2021
To investigate the survival status of patients living with human immunodeficiency virus(HIV)/acquired immunodeficiency syndrome(AIDS) receiving antiretroviral therapy in the integrated HIV prevention and treatment demonstration zone of Chongqing,China,and to explore the factors influencing patients’ survival.
Methods
2
A retrospective cohort study was performed to analyze the survival of patients aged ≥18 years who received antiretroviral treatment for the first time in the demonstration zone from 2016 to 2021. The survival rate was calculated by using the life-table method. The risk factors affecting death were analyzed using a Cox proportional hazards model.
Results
2
A total of 21 506 subjects were included in the study. A total of 54 919.63 person-years were followed up. The all-cause mortality rate was 3.67/100 person-years. The cumulative survival rates of 12,36,and ≥72 months since the initiation of antiretroviral therapy were 94.09%,88.65%,and 82.98%,respectively. The multivariable Cox proportional hazards regression analysis showed that the death risk of women was 0.54 times that of men. The risk of death for patients with treatmen
t initiated at age of ≥60 years was 4.38 times that of those with treatment initiated at age of 18-30 years. The death risk of homosexually transmitted infection was 0.65 times that of heterosexually transmitted infection. In terms of the baseline number of CD4
+
T cells,the risks of death in the groups of 200-349 cells/μL and ≥350 cells/μL were 0.61 and 0.49 times that of the group of 0-199 cells/μL,respectively. In terms of the interval between diagnosis and treatment,compared with the group of
<
30 days,the groups of 31-90 days,91-365 days,and
>
365 days were 1.25,1.56,and 1.74 times more likely to die of HIV/AIDS,respectively. The death risks with other first-line treatments and second-line treatments were 1.47 and 1.65 times that with standard first-line treatments,respectively.
Conclusion
2
The mortality rate is decreased in patients with HIV/AIDS receiving antiretroviral therapy in the Chongqing demonstration zone. Early detection and treatment of HIV/AIDS should be strengthened for patients with a high risk of death,those with treatment beginning at age of ≥60 years,a low baseline CD4
+
T cell count,and a long interval between diagnosis and first treatment.
