目的了解重庆市渝北区结核病人人类免疫缺陷病毒(HIV)感染现状及流行病学特征,为制定结核病(TB)/HIV双重感染防治对策提供依据。方法采用连续抽样的方法,对渝北区疾病预防控制中心结核病门诊2011年1月-2015年12月的结核病患者,用酶联免疫吸附实验(ELISA法)进行HIV抗体初筛,对HIV抗体初筛阳性标本送重庆市疾病预防控制中心做免疫印迹(WB)确证实验。结果对2 826例结核病患者进行了HIV抗体检测,其中HIV抗体阳性者34人,阳性率为1.20%;34例阳性者中已知HIV抗体阳性者1例,占2.94%,新发现33例占97.06%。结论渝北区结核病患者的HIV感染率高于重庆市结核病患者的HIV感染率平均水平,远高于重庆市HIV感染率平均水平,有必要加强双重感染防控工作。
Objective To understand the current status and epidemiological characteristics of human immunodeficiency virus (HIV) infection in TB patients in Yubei district of Chongqing and provide evidence for the prevention and treatment of TB / HIV infection. Methods A continuous sampling method was used to detect HIV antibody in tuberculosis patients from January 2011 to December 2015 in Yubei District Center for Disease Control and Prevention by enzyme-linked immunosorbent assay (ELISA) Positive samples of sieve were sent to Chongqing Center for Disease Control and Prevention for Western blot (WB) confirmation experiment. Results A total of 2 826 TB patients were tested for HIV antibody, of which 34 were HIV-positive, with a positive rate of 1.20%. Among the 34 positive cases, 1 was HIV-positive, accounting for 2.94%, and 33 newly found cases 97.06%. Conclusion The HIV infection rate of TB patients in Yubei District is higher than the average HIV infection rate of TB patients in Chongqing and far higher than the average level of HIV infection in Chongqing. It is necessary to strengthen the prevention and control of double infection.
