摘 要:目的探讨既往不安全有偿供血感染艾滋病病毒(HIV)者生存时间及其影响因素。方法采用回顾性队列研究方法,从山西、山东、湖北、吉林4个省以典型抽样方式选取8个县(区),选择所有2006年1月24日前发现并确认既往不安全有偿采血(浆)者中HIV感染者和艾滋病(AIDS)患者病例,收集其感染、发病、死亡等信息及影响因素。结果530例病例中,HIV感染者196例(37.0%);AIDS患者334例(63.0%),其中168例(50.3%)抗病毒治疗;152例(29.0%)死亡。在530例患者从感染到观察终点平均观察(10.1±1.8)年中,166例未治疗AIDS患者平均生存时间9.1年(95%CI:9.1—9.4),8年生存率52.0%;而168例已治疗AIDS患者平均生存时间12.1年(95%CI:11.9~12.3),12年生存率80.0%;在抗病毒治疗3年中,治疗者平均生存时间比未治疗者延长而死亡风险降低12.2倍。AIDS患者平均生存时间在性别、年龄、地区、是否高效抗逆转录病毒治疗(HAART)、治疗前基线CD4^+T淋巴细胞水平上存在差异,多因素COX回归分析表明抗病毒治疗是AIDS患者生存首要保护因素(HR=13.3,P=0.00),治疗前基线CD4^+T淋巴细胞〈50个/μl的AIDS患者治疗中死亡风险高(HR=10.9,P=0.00)。结论AIDS患者生存时间受到诸多因素影响,但是HAART干预是延长AIDS患者生存时间和降低AIDS患者死亡风险的首要保护措施。Objective To investigate HIV survival time and it's influencing factors among former commercial blood and plasma donors engaged in unsafe blood donation practices in China. Methods HIV/ AIDS cases from 8 counties (districts) in 4 provinces confirmed prior to January 24,2006 related with former commercial blood and plasma donors were selected and data regarding infection, AIDS progression, death, and influencing factors were retrospectively collected. Results In 530 cases of HIV infection, 334 (63.0%) cases had developed AIDS, 168 ( 50. 3% ) had received antiretroviral therapy ( ART), and 152 ( 29. 0% ) had died. For the 530 eases, there was an average ( 10. 1 ± 1.8 ) years of observation from time of infection. Among 166 AIDS patients not receiving ART, average survival was 9. 1 years (95% CI: 9. 1 - 9.4) ,with an 8 year survival rate of 52.0%. Among 168 AIDS patients receiving ART,average survival was 12. 1 years (95% CI: 11.9- 12.3),with a 12-year survival rate of 80.0%. In 3 years of ART,average survival was longer in the treatment group as compared to the no treatment group with a hazard ratio for death of 12. 2. Univariate analysis showed a significant difference (P 〈 0. 05 ) in AIDS patient average survival based on gender, age, location, ART status, and baseline CD4 Tcells count. Results from multivariate COX- regression showed that highly active ant iretroriral therapy(HAART) was the strongest protective factor for prolonging AIDS patients' survival (HR= 13.3,P=0. 00). Conclusion Although there are many factors influencing AIDS patients survival,intervention with HAART is the principle measure to prolong survival and decrease the risk of death.
