AIM
Until now, the performance of interferon-γ release assay (IGRA) and Mantoux tests remains unclear in infant tuberculous meningitis (TBM). Therefore, a systematic review is performed to evaluate the sensitivity of IGRA and Mantoux tests for the diagnosis of infant TBM in low and intermediate tuberculosis (TB) burden countries, while following PRISMA.
METHODS
Several databases, including PubMed, EBSCO, Embase, Scopus, Web of Science, ClinicalTrials.gov, and Cochrane Central Register of Controlled Trials, were searched. Articles describing the results of IGRA or Mantoux tests among infant TBM were included for analysis. Data, such as age, sex, Mantoux test or IGRA, and cerebrospinal fluid (CSF) microbiological examinations (such as acid-fast bacilli (AFB) smear, TB PCR, and TB culture), were extracted from each study.
RESULTS
A total of 31 articles were enrolled for further analysis, including 48 cases. The mean age was 9.4 ± 5.8 months and boys accounted for 57.1% of infants (24/42). Mantoux test was positive in 57.4% (27/47) of tested infants and IGRA was positive in 77.8% (7/9) of infants. In addition, among the infants with confirmed TB, 18 (52.9%, 18/34) of them have positive Mantoux responses and 7 (20.0%, 7/35) have positive IGRA results.
CONCLUSIONS
In low or intermediate TB burden countries, the Mantoux test has a poor performance for diagnosing TBM among infants, and IGRAs appear to have a moderate sensitivity for the diagnosis of infant TBM.

Comparative Study Review
OBJECTIVE
To compare the sensitivity, specificity and efficiency between Mantoux and Interferon-gamma techniques, using secondary sources.
DESIGN
Study of the published literature with a high evidence-based sources of scientific information.
DATA SOURCES
A bibliographic search in the Cochrane database and Trip-database.
STUDY SELECTION
We found three Clinical Practice Guidelines and nine articles, which included one Systematic Review, one Meta-analysis, one article on the sensitivity of the new techniques, three cost-efficiency studies, and three prospective studies on the role of interferon-gamma release in the diagnosis of TB.
RESULTS
The new techniques have a higher specificity than Mantoux for the diagnosis of LTBI in contacts vaccinated in childhood with BCG. The most cost-effective diagnostic strategy for LTBI was Mantoux screening and confirmation with QFT-G.
CONCLUSION
Resources should be coordinated, limiting its use in studies of contacts in immunocompetent adults vaccinated with BCG, with Mantoux>5mm or Tuberculin doubtful cases.
