摘要: 目的探讨结核感染T细胞斑点实验(T-SPOT.TB)在临床快速诊断结核病中的应用价值。方法利用T-SPOT.TB方法检测外周血中结核感染特异的效应T淋巴细胞的频率。同时与涂片抗酸染色、BACTEC960培养及实时定量PCR方法做比对。结果164例结核病患者中,155例T-SPOT.TB阳性,提示方法敏感度为94.5%(155/164),显著高于其他方法。60例非结核呼吸道疾病对照组中有5例阳性,20例健康对照均为阴性,方法的特异度为93.8%(75/80)。结论T-SPOT.TB方法敏感度和特异度均非常高,可用于结核病的快速诊断,尤其是对于结核病和非结核分枝杆菌病的早期鉴别。

Abstract: ObjectiveTo evaluate the clinical application of T-SPOT.TB in the rapid diagnosis of active tuberculosis.MethodsThe blood samples were detected interferon-gamma (IFN-γ) released by T lymphocytes, which were activated by specific M.tuberculosis antigens using T-SPOT.TB, and comparing with smear and acid-fast staining, BACTEC 960 culture and real-time PCR. Results155 of 164 M.tuberculosis patients were positive,the sensitivity of T-SPOT.TB was 94.5%(155/164),significantly higher than other methods.5 cases were positive in 60 cases with non-tuberculosis respiratory disease, and 20 healthy subjects were negative, the specificity of the method was 93.8% (75/80).ConclusionsT-SPOT.TB is a sensitive and specific method for rapid diagnosis of tuberculosis,especially suitable for early distinguishing TB with NTM.
