“…Our results, showing that 8/15 TST + /QFT -children screened positive with our IP-10 release assay, agree with the concept that combining IFN-γ and IP-10 testing may be one approach to increase the sensitivity of QFT in young children [6]. Our results also agree with previous studies showing an IL-13 response to M.tb peptides in pediatric TB [7][8][9].…”

“…however, IGRAs more often present with indeterminate or false negative results, which is particularly the case for young and immune-compromised children [2,[4][5][6][7]. Identification of novel cytokine biomarkers that can improve the performance of IGRAs (independently or in combination with IFN-γ) has been evaluated by several studies [8][9][10]. These studies demonstrated that additional cytokines and cytokine combinations might contribute to the detection of M. tuberculosis infection and active tuberculosis in children [8,[11][12][13].…”

IFN-γ release assays (IGRAs) often present false-negative or indeterminate results in children with tuberculosis. HIV co-infection may contribute to decreased sensitivity of IGRAs by impairing T-cell IFN-γ expression. Measurement of alternative cytokines in QuantiFERON (QFT) supernatants can circumvent the IFN-γ-dependency and may improve QFT sensitivity. We aimed to identify additional cytokines from QFT supernatants for detection of Mycobacterium tuberculosis infection in children with tuberculosis and HIV co-infection from Ghana. Concentrations of 18 cytokines in QFT supernatants from children (0-16 years) with tuberculosis concomitantly infected with HIV (n = 25) or without HIV (n = 24) from Ghana were measured using cytometric bead array (CBA). 29% of the children showed positive IFN-γ test results, and five cytokines, i.e., IL-6, IL-21, TNF-α, IL-1α and IP-10, detected M. tuberculosis infection with comparable or, for IL-6, with significantly higher sensitivity (59%). Increased age and HIV co-infection were associated with decreased cytokine induction, and especially IL-21 and IP-10 were less prevalent in HIV co-infected children with tuberculosis. Combined cytokine analyses increased proportions of positive tests, and a four-cytokine subset (i.e., IL-6, IL-21, IFN-γ, IL-1α) predicted 78% of the children with tuberculosis correctly. Combined evaluation of IFN-γ and alternative cytokines improved IGRA-sensitivity in children with tuberculosis.

“…A similar approach combining the QGIT, TST, and cytokine profiles was assessed by Tebruegge and colleagues looking at 149 children with possible TB (12). The cytokine profiles assessed included IFN-g, IFN-inducible protein-10 (IP-10), tumor necrosis factora, IL-1ra, IL-2, IL-13, and macrophage inflammatory protein-1b, and the study assessed whether combinations of the cytokine profiles in addition to the results of the TST and QGIT could distinguish between latent and active TB.…”
