[Survival time and related factors of antiretroviral therapy among HIV/AIDS patients in Liangshan Prefecture, during 2005-2015].

Objective: To analyze the survival time and to explore the releated factors of antiretroviral therapy among HIV/AIDS patients in LiangShan Prefecture, Sichuan Province for reduction of AIDS death rate. Methods: The retrospective research method was used to collect relevant information from the Management Database of Antiviral Treatment from the National AIDS Comprehensive Prevention Information System. The Kaplan-Meier method was used to describe the survival distribution and to analyze the survival time by single factor and the model of Cox proportional riskanalysis was performed to analyze the survival time of HARRT by multi-factors analysis. Results: Total 14 219 adults and young persons aged ≥15 HIV/AIDS patients received antiviral treatment from 2005 to 2015. The average age of all cases was (36.10±9.41) years old and 10 021 were males (70.5%). The main route of infection was intravenous drug use (61.0%, 8 678 cases). At the end of the observation, 10001 cases (70.3%) were still treated, and 1 425 cases (10.0%) died; Cox Regression analysis showed that female (0.67 (0.55-0.81)), route of sexual infection (0.67 (0.56-0.79)), baseline CD4+T lymphocyte count 200-350 (0.41 (0.35-0.47)) and ≥350 (0.28 (0.24-0.34)), was a protective factor in death. At the beginning of treatment, the patient is clinically staging stage Ⅱ (0.70 (0.58-0.84)) and abnormal BMI (1.75 (1.50-2.03)), is a risk factor for death (P<0.05). Conclusion: Early antiviral treatment is of great significance in improving the anti-viral treatment effect of AIDS. Compliance education should be further strengthened so as to enhance their knowledge. And it is feasible to enhance the effect of treatment through nutritional support for prolonging patients survival time and improving the quality of life.

[Effects and associated factors of HIV/AIDS anti-retroviral therapy in Liangshan Yi Autonomous Prefecture, Sichuan Province].

Objective: To evaluate the effectiveness and to explore the releated factors of antiretroviral therapy among HIV/AIDS patients in Liangshan Yi Autonomous Prefecture, Sichuan Province. Methods: The method of convenience sampling was adopted in July 2017 to select the research objects who were accepted antiretroviral therapy (ART) over 6 months, older than 18 years and had HIV viral load in 2016, totally 400 cases. A retrospective study was used to collect the data, including social demography, medicine use, information of medical service acquisition, their own behaviors and cognition. 395 questionnaires were effectively recovered. χ(2) test and logistic regression were performed to examine relationships between factors and effects. Results: All of the 395 respondents were Yi-nationality. The average age of all cases was (39.23±7.52) years old and 223 were male (56.5%). Among 395 cases patients who were detect Viral load in 2016, 221 cases were under the number of 400 copies, thze effective rate of ART was 55.9%. Multivariate analysis showed that HIV/AIDS patients who missed the medication during the antiviral therapy had poor antiviral effects. Compared to those who adhered to medication, the treatment-ineffective OR (95%CI) of the patients missing the medication during the therapy was 7.06 (3.67-13.58); Compared to those who had adverse reactions that affect the therapy, the treatment-ineffective OR (95%CI) of the patients with mild adverse reactions that did not affect the therapy was 0.45 (0.23-0.87); Compared to the patients who used drugs during the treatment, the treatment-ineffective OR (95%CI) value of the antiretroviral therapy effect of non-drug users was 0.39 (0.16-0.91);Compared to the patients who have a correct cognition that insisting on taking medicine correctly can extend their life expectancy as a common person, the treatment-ineffective OR (95%CI) values for those who hold the view that could be prolonged by 10-20 years and not/unknown were 4.18 (1.59-10.99) and 6.64 (2.67-16.53). Conclusion: The HIV/AIDS patients who receive ART were less effective in Liangshan, Prefecture. Missings drugs is one of the main influencing factors for the ineffective treatment.

[Epidemiological analysis of the deaths with antiretroviral treatment among adult HIV/AIDS patients in Liangshan Yi Autonomous Prefecture from 2005 to 2015].

Objective: To analyze the deaths with antiretroviral treatment among adult HIV/AIDS patients in Liangshan Yi Autonomous Prefecture from 2005 to 2015, in order to understand the epidemiological characteristics and to further reduce the mortality rate in Liangshan Prefecture. Methods: The relevant information was collected through the Management Database of Antiretroviral Treatment from the National AIDS Comprehensive Prevention Information System. Results: From 2005 to 2015, a total of 14 219 adult HIV/AIDS patients received antiretroviral treatment and 1 425 death cases were reported during the treatment. The cause of death was mainly AIDS-related diseases (58.9%), and the cumulative mortality rate was 10.02%. Gender, age, the way of infection, duration of antiretroviral therapy, clinical stage when received antiretroviral therapy, and CD(4)(+) T lymphocyte levels were factors for the mortality rate (P<0.001). The mortality increased with older age, higher initiation clinical stage and lower level of CD(4)(+) T lymphocyte. Among the death cases, 82.6% were male, 1 182 (82.9%) were married or cohabited, most aged between 30-39 years old (48.6%). At the initial point of receiving antiretroviral therapy, 49.7% of the cases with CD(4)(+)T lymphocytes levels< 200/µl, 61.2% of the deaths cases were>1 000 copies/ml during the last viral load test, and 16.2% of deaths were ≥500/µl in the last CD(4)(+)T lymphocyte test; 44.5% of deaths were received antiretroviral treatment within one year. Conclusion: Early and timely antiretroviral therapy should be carried out. It is necessary to strengthen the propaganda of antiretroviral therapy and to improve the management quality of follow-up information of antiretroviral therapy case files, and to improve the medication compliance of patients.
