ABSTRACT
BACKGROUND:
Lymphadenopathy is one of the most prevalent clinical manifestations of extrapulmonary tuberculosis. Endosonography is the recommended technique in the diagnostic work-up of mediastinal lymphadenopathies. Xpert MTB/RIF assay is a self-contained cartridge-based fully automated DNA testing platform which can accurately detect both tuberculosis and mycobacterial resistance to rifampicin. A few studies assessed its accuracy for mediastinal lymph node aspirates collected using endosonography. A systematic review of observational studies was performed to provide a pooled estimate of sensitivity and specificity of Xpert MTB/RIF in the diagnosis of mediastinal tuberculous lymphadenitis using endoscopic ultrasound-guided needle aspiration techniques.METHODS:
A search of the scientific evidence was carried out using PubMed, Embase, and Scopus. Articles describing observational studies on Xpert MTB/RIF in the diagnosis of mediastinal tuberculous lymphadenitis using endoscopic ultrasound-guided needle aspiration techniques were selected.RESULTS:
Eight studies met the inclusion criteria. The overall pooled sensitivity was 61% (95% CI = 55-68%; I2 = 66.3%; p = 0.004), overall pooled specificity was 89% (95% CI = 85-91%; I2 = 90.1%; p < 0.0001). Area under the sROC curve was 0.68. Only one study reported data on rifampin resistance detection and showed a sensitivity of 83.3% and a specificity of 16%.CONCLUSIONS:
Xpert MTB/RIF shows a good accuracy in the diagnosis of mediastinal mycobacterial lymphadenitis by endosonographic needle aspiration techniques. It should be always recommended for suspected mediastinal tuberculosis.Palavras-chave
