摘要: 目的 探讨结核分枝杆菌复合群(MTD)检测在获得性免疫缺陷综合征(AIDS)合并结核分枝杆菌感染实验诊断的临床应用。方法 采用MTD、结核分枝杆菌培养及抗酸染色3种方法,对127例AIDS合并疑似分枝杆菌感染患者的痰样本进行同步检测,对照组为同期住院非人类免疫缺陷病毒(HIV)感染的普通疑似结核病患者25例。结果 127例AIDS患者痰样本MTD阳性率为29.1%;结核分枝杆菌培养法阳性率为25.2%;抗酸染色阳性率为18.9%;对照组MTD和结核分枝杆菌培养法的阳性率均为44.0%,抗酸染色阳性率为40.0%。结论 MTD对AIDS合并结核病的诊断有较高的应用价值,在提高阳性率的同时可在1个工作日内提供结核分枝杆菌感染的实验诊断信息。

Abstract: Objective To investigate the clinical application of Mycobacterium tuberculosis direct(MTD) test in the diagnosis of acquired immune deficiency syndrome(AIDS) co-infection with tuberculosis. Methods The sputum samples of 127 AIDS patients suspected of tuberculosis co-infection were determined by MTD test, Mycobacterium tuberculosis culturing and acid-fast stain test. Sputum samples of 25 inpatients suspected of tuberculosis without human immunodeficiency virus(HIV) infection were analyzed as controls. Results The sputum positive rates of the 127 AIDS patients were 29.1%, 25.2% and 18.9% by MTD test,Mycobacterium tuberculosis culturing and acid-fast stain test, respectively. The positive rates of the controls were 44.0%, 44.0% and 40.0% by MTD test, Mycobacterium tuberculosis culturing and acid-fast stain test,respectively. Conclusions MTD test has application value in AIDS patients suspected of tuberculosis co-infection. It can improve the positive rate and provide the laboratory results within 1 d.
