To evaluate the application of interferon gamma release assay (IGRA), rifampicin resistant real-time fluorescence quantitative PCR technique Xpert Mycobacterium tuberculosis/rifampicin (Xpert MTB/RIF), and the levels of TNF-α and TGF-β in the diagnosis of bone and joint tuberculosis.
Eighty-six patients with bone and joint tuberculosis, diagnosed by pathology or microbiology, were examined by Xpert MTB/RIF and IGRA (T-SPOT. TB) for Mycobacterium tuberculosis infection, and the TNF-α and TGF-β levels of the patients were measured.
The sensitivity of IGRA in diagnosing bone and joint tuberculosis was 81.4%; Xpert MTB/RIF's sensitivity was 70.9%. The combined sensitivity of the two methods was 91.9%. The combined detection sensitivity of the two methods was higher than individual IGRA or Xpert MTB/RIF detection sensitivity. The TNF-α and TGF-β levels in bone and joint tuberculosis patients were higher than those in the control group.
Xpert MTB/RIF, IGRA, TNF-α, and TGF-βs expression have value in the rapid diagnosis of bone and joint tuberculosis, and the sensitivity and accuracy of bone and joint tuberculosis diagnosis by combining them can improve it.
评估γ-干扰素释放试验(IGRA)、利福平耐药实时荧光定量PCR技术Xpert结核分枝杆菌/利福平(Xpert MTB/RIF)以及肿瘤坏死因子-α(TNF-α)和转化生长因子-β(TGF-β)水平在骨与关节结核诊断中的应用。
选取86例经病理或微生物学确诊的骨与关节结核患者,采用Xpert MTB/RIF和IGRA(T-SPOT.TB)检测结核分枝杆菌感染情况,并检测患者的TNF-α和TGF-β水平。
IGRA诊断骨与关节结核的灵敏度为81.4%;Xpert MTB/RIF的灵敏度为70.9%。两种方法的联合灵敏度为91.9%。两种方法联合检测的灵敏度高于单独的IGRA或Xpert MTB/RIF检测灵敏度。骨与关节结核患者的TNF-α和TGF-β水平高于对照组。
Xpert MTB/RIF、IGRA、TNF-α和TGF-β的表达在骨与关节结核的快速诊断中具有价值,联合应用可提高骨与关节结核诊断的灵敏度和准确性。
