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.
目的： 分析四川省凉山州艾滋病抗病毒治疗患者接受抗病毒治疗后生存时间及影响因素。 方法： 采用回顾性研究方法收集相关信息，选取国家艾滋病综合防治数据信息系统中的艾滋病患者为研究对象。纳入标准为：2005—2015年在凉山州接受抗病毒治疗且年龄≥ 15周岁的HIV感染者/艾滋病患者，共14 219例。采用Kaplan-Meier法绘制生存曲线，进行抗病毒治疗患者生存时间的单因素分析，采用Cox比例风险模型进行多因素分析。 结果： 研究对象的年龄为（36.10±9.41）岁，其中男性10 021例，占70.5%，感染途径以静脉吸毒为主（61.0%，8 678例）；至随访观察终止时间，依然在治者10 001例（70.3%），死亡1 425例（10.0%）；Cox回归分析结果显示，女性［HR（95%CI值）=0.67（0.55~0.81）］、性感染途径［HR（95%CI值）=0.67（0.56~0.79）］，CD4+T淋巴细胞计数在200~350［HR（95%CI值）=0.41（0.35~0.47）］及≥350者［HR（95%CI值）=0.28（0.24~0.34）］，是死亡的保护性因素，而开始治疗时患者临床分期Ⅱ期［HR（95%CI值）=0.70（0.58~0.84）］，以及体重指数异常［HR（95%CI值）=1.75（1.50~2.03）］是死亡的危险因素（以上P值均<0.05）。 结论： 早期进行抗病毒治疗对提高艾滋病抗病毒治疗效果有重要意义，应进一步加强HIV感染者/AIDS患者抗病毒治疗相关知识宣传教育，提高患者治疗依从性，还可通过营养支持的方式，增强患者体质，从而延长其生存时间，提高生存质量。.
