OBJECTIVE: To evaluate the diagnostic accuracy of interferon-gamma release assays (IGRAs) for diagnosing tuberculous meningitis (TBM).
DESIGN: The EMBASE and PubMed databases were systematically searched to identify studies published by 2 May 2015 investigating the diagnostic accuracy of IGRA for TBM. The quality of the included studies was assessed using the revised Quality Assessment for Studies of Diagnostic Accuracy (QUADAS-2) method. The overall diagnostic accuracies of an IGRA for cerebrospinal fluid (CSF) or blood were pooled using a bivariate model.
RESULTS: Eight studies using blood IGRA and 6 studies using CSF IGRA were included. The overall sensitivities for blood and CSF IGRA were respectively 0.78 and 0.77, and the specificities were 0.61 and 0.88. The areas under the summary receiver operating characteristic curves were respectively 0.76 and 0.83 for blood and CSF IGRA. The major design weaknesses of the studies included were patient selection bias and exclusion of uninterpretable results.
CONCLUSION: The diagnostic accuracy of blood and CSF IGRA in case of TBM is moderate.
