目的探索结核病人群中HIV感染调查的方法,了解郑州地区结核病人群中HIV感染状况。方法采用连续抽样和关联保密法,对郑州地区7个结防机构2007年8月11日—11月31日就诊的活动性结核病人,用酶联免疫吸附试验(ELISA)进行HIV初筛,初筛阳性者做免疫印迹(WB)确认试验,并进行问卷调查。结果调查新登记结核病1583例,HIV阳性者9例,感染率0.57%;HIV感染病人年龄在13~60岁,男性组HIV感染率0.63%,女性组感染率为0.21%;不同年龄活动性结核病人中HIV感染者主要集中在青壮年,占88.9%;农村户口结核病人HIV感染率0.62%,城镇户口结核病人HIV感染率0.43%。固定人口HIV感染率0.67%,流动人口HIV感染率0.37%;HIV感染途径,采血浆、输入血液传播4例(44.4%),异性传播2例(22.2%)。结论关联保密法来调查结核病人群中HIV感染状况是可行的,郑州地区结核病人群中HIV感染率0.57%。
Objective To explore the method of HIV infection in TB population and understand the status of HIV infection in TB population in Zhengzhou area. Methods A continuous sampling and correlation-based confidentiality test was used to screen HIV-positive HIV-positive patients with active tuberculosis (TB) who were admitted to TB control institutions in Zhengzhou from August 11 to November 31, 2007 by ELISA Screen positive for immunoblot (WB) confirmation test, and the questionnaire. Results A total of 1583 new cases of tuberculosis were registered and 9 were HIV-positive, with an infection rate of 0.57%. HIV-infected patients were 13 to 60 years old. HIV infection rate was 0.63% in males and 0.21% in females. Active tuberculosis HIV-infected patients in patients mainly concentrated in young adults, accounting for 88.9%; rural hukou TB HIV infection rate of 0.62%, urban hukou TB HIV infection rate of 0.43%. HIV infection rate was 0.67% in fixed population and 0.37% in floating population. In HIV infection route, blood plasma was taken in 4 cases (44.4%) and heterosexual transmission in 2 cases (22.2%). Conclusion It is feasible to investigate the status of HIV infection among tuberculosis patients by using the confidential-confidential method. The prevalence of HIV infection in TB population in Zhengzhou is 0.57%.
