[Survival time of HIV/AIDS death cases after antiretroviral therapy and related factors in Henan province, 2003-2015].

Objective: To analyze and investigate the survival time of dead HIV/AIDS patients after antiretroviral therapy (ART) and related factors in Henan province. Methods: The database of national integrated management system of HIV/AIDS was used to collect the information of dead patients who received ART between January 2003 and December 2015. Software SPSS 23.0 was used to analyze the survival time of dead patients and related factors. Result: A total of 6 267 AIDS patients died after ART and the average survival time was 23.85 months ( Q(R) : 6.87-50.46 months). Within 6 months, 7-12 months and 13-24 months after ART, the numbers of dead patients were 1 441 (23.00%), 652 (10.40%) and 1 052 (16.79%), respectively. The number of dead cases decreased after 24 months of ART. The number of AIDS-related deaths was 5 085 (81.1%); and 799 (12.7%) deaths were due to other causes, in which 179 (2.9%) were caused by accidents and 109 (1.7%) were caused by suicides. The differences in annual composition ratio of death causes during 2003-2015 had significance ( χ (2)=864.27, P <0.01). Twelve months, 36 months, 60 months and 120 months after ART, the survival ratios were 66.59%, 36.62%, 19.24% and 0.64% respectively. Compared with patients infected through blood donation, the HR of the patients infected through sexual transmission was 1.602 (95 %CI: 1.483-1.732). Compared with patients with initial level of CD(4)(+)T lymphocyte ≥350 unit/μl, the HR of patients with initial level of CD(4)(+)T lymphocyte<50 unit/μl was 2.320 (95 %CI : 2.119-2.539). Compared with patients receiving second line ART, the HR of patients receiving no second line ART was 3.312 (95 %CI : 3.083-3.558). Conclusion: The AIDS related deaths mainly occurred in the first six months after ART. As the increase of duration of ART, the death rate decreased. Sexual transmission, low initial level of CD(4)(+)T lymphocyte and receiving no second line ART were the risk factors for the deaths of HIV/AIDS patients.
