QuantiFERON TB Gold Plus for the diagnosis of tuberculosis : a systematic review and meta-analysis / G. Sotgiu, L. Saderi, E. Petruccioli, S. Aliberti, A. Piana, L. Petrone, D. Goletti. - In: JOURNAL OF INFECTION. - ISSN 0163-4453. - 79:5(2019 Nov), pp. 444-453. [10.1016/j.jinf.2019.08.018]
Abstract:
Estimated 2017 tuberculosis (TB) incidence is 10 million and mainly depends on the reservoir of individuals with latent TB infection (LTBI). QuantiferonⓇ-TB Gold in-Tube (QFT-GIT) is one of the tests used for LTBI detection. Since 2015 a new version, QuantiferonⓇ-TB Gold Plus (QFT-Plus) is available.
OBJECTIVES:
To perform a systematic review and meta-analysis to assess the diagnostic accuracy for TB of QFT-Plus compared to QFT-GIT.
METHODS:
PubMed and Scopus were used to detect records related to predefined strings from 2015 to 2018. Full text articles dealing with the sensitivity and/or specificity of the QFT-Plus vs. QFT-GIT for active-TB and LTBI detection were analyzed. Scientific quality and risk of bias were assessed using QADAS-2.
RESULTS:
We selected 15 articles. Studies were mainly observational and cross-sectional, performed in 8 countries. Sample size differed in the TB group (27 to 164) compared to LTBI group (29 to 1031). Pooled sensitivity of QFT-Plus for active-TB was 0.94 (0.91 and 0.95 for TB1 and TB2, respectively), whereas pooled specificity for healthy status was 0.96. Pooled sensitivity and specificity for LTBI was 0.91 and 0.95, respectively.
CONCLUSIONS:
We show that QFT-Plus is more sensitive compared to QFT-GIT for detecting M. tuberculosis infection, mainly due to TB2 responses.
