摘  要:目的探讨γ-干扰素释放试验对老年肺结核的辅助诊断价值。方法按整体随机抽样原则选取2012年10月至2014年10月首都医科大学附属北京胸科医院行酶联免疫斑点试验(enzyme-linked immunospot,ELISPOT)检查的住院老年肺结核患者408例,住院中青年肺结核患者202例及住院老年原发性肺癌患者201例。收集所有患者的ELISPOT检测结果,同时收集老年肺结核患者的一般人口学信息、临床特征及辅助检查资料等。组内及组间构成比或率的比较采用X2检验,以X2检验P〈0.05的因素作自变量,以ELISPOT结果为阳性或阴性作为因变量,行多因素非条件logistic回归分析。结果(1)老年肺结核组ELISPOT阳性率为84.07%(343/408),低于中青年肺结核组(93.07%,188/202)(X2=9.709,P=0.002)。(2)老年肺结核患者中,ELISPOT阳性率女性为90.08%(109/120),高于男性(81.25%,234/288)(X2=5.808,P=0.016);非吸烟者(88.24%,180/204)高于吸烟者(79.90%,163/204)(f=5.289,P=0.021);初治者(86.64%,253/292)高于复治者(77.59%,90/116)(X2=5.085,P=0.024);痰涂片阳性者(90.64%,184/203)高于阴性者(76.27%,135/177)(X2=14.488,P=0.000);痰培养阳性者(90.32%,196/217)高于阴性者(72.09%,93/129)(X2=19.539,P=0.000)。logistic回归分析显示,仅痰培养与其密切相关(Wald)[2=7.412,P=0.006,OR=2.685,95%CI=1.319~5.468)。(3)不同检测方法比较,老年肺结核患者ELISPOT的阳性检出率为84.07%(343/408),高于痰涂片(53.42%,203/380)(X2=86.847,P=0.000)、痰培养(62.72%,217/346)(X2=44.667,P=0.000)及结核抗体检测(68.35%,244/357)(x2=26.358,P=0.000)。在与老年原发性肺癌的鉴别诊断中,ELISPOT敏感度为84.0Objective To evaluate the diagnostic value of interferon-gamma release assay (IGRAs) in elderly patients with pulmonary tuberculosis (PTB). Methods We selected 408 cases of elderly hospitalized patients with PTB, 202 cases of young hospitalized patients with PTB and 201 cases of elderly hospitalized patients with primary lung cancer who received enzyme-linked immunospot (ELISPOT) during October 2012 to October 2014 in Beijing Chest Hospital, Capital Medical University. We collected the ELISPOT result in all the study cases and the data of general demographic, clinical characteristics and auxiliary examinations in elderly hospitalized patients with PTB. We used the 22 test to compare the radio within and between groups. Multivariate logistic regression analysis was done taking the P〈0. 05 factors as the independent variables and the results of ELISPOT as the dependent variable. Results (1) The positive rate of ELISPOT in elderly patients with PTB was 84.07% (343/408) which was lower than the young patients with PTB 93.07% (188/202) (X2 = 9.709, P = 0.002). (2) In the elderly patients with PTB, the positive rate of ELISPOT in female patients 90. 08% (109/120) was higher than that in male patients 81.25% (234/288) (X2 = 5.808, P= 0.016), non-smoker 88.24% (180/204) was higher than smokers 79. 90% (163/204) (X2 = 5.289, P=0.021), untreated 86.64% (253/292) was higher than treated 77.9% (90/116) (X2 = 5. 085, P=-0.024), smear positive 90.64% (184/203) was higher than smear negative 76.27% (135/177) (X2 = 14.488, P= 0.000), culture positive 90.32% (196/217) was higher than culture negative 72.09% (93/129) (X2 = 19.539, P= 0.000). But the logistic regression analysis showed that only culture positive had a close relationship with the positive rate of ELISPOT (Wald X2=7.412, P=0.006, OR=2.685, 95% CI: 1.319 - 5.468). (3)Among the different detection methods, the positive rate of ELISPOT 84.07% (343/408) was higher
