摘要 目的:评估QuantiFERON-TBGold(QFT-G)试验在筛查结核病(TB)接触者、以及评估其发展为活动性结核病的风险方面的效果。方法:收集公共卫生中心结核病密切接触者接受QFT-G试验2年后,临床进展为活动性结核病的资料。结果:3102例观察的接触者中,有419例QFT-G阳性,其中323例开始异烟肼(INH)治疗。419例中的20例(4.8%)发展为结核病。在平均随访的1.6年时间里,2683例QFT-G-阴性人群中,19例被诊断为结核病(0.7%)。QFT-G对于检测可能发展为活动性结核病的接触者的敏感性估计为51%,对于进行异烟肼治疗估计的敏感性为64%。在QFT-G阴性接触者中,所有发展为结核病的都是高度传染病例的接触者。没有进行大规模的结核分枝杆菌素皮肤试验。结论:QFT-G阳性接触者中结核病发病率比QFT-G阴性接触者要高,但是QFT-G阴性接触者中的结核病病例数也是不可忽视的,尤其是具有高传染性结核病例的接触者。
