Variation in interferon-γ production between QFT-Plus and QFT-GIT assays in TB contact investigation

Respiratory Investigation, 2019
Individuals with recent contact with active tuberculosis (TB) patients were screened for latent tuberculosis infection (LTBI) considering their greater relative risk for developing active TB. QuantiFERON®-TB Gold Plus (QFT-Plus) assay offers two TB-specific antigen tubes (TB1 and TB2). TB2 is designed to elicit both CD4 and CD8 T-cell responses.

Diagnostic performance in active TB of QFT-Plus assay and co-expression of CD25/CD134 in response to new antigens of Mycobacterium tuberculosis

Medical Microbiology and Immunology, 2019
The new QuantiFERON-TB Gold Plus employs modified peptides optimized to elicit an IFNγ response from CD8+ cytotoxic T lymphocytes in addition to CD4+ T cells. With a view to improve the difficult identification of TB cases, we assessed the combination of two specific immunological markers comprising IFNγ secretion and T cells co-expression of CD25 and ...

Evaluating and Optimizing Quantiferon-TB Gold Plus (QFT-Plus) for Pediatric Tuberculosis (TB) and Latent TB Infection (LTBI) Screening in Northern China's Children With Underlying Health Conditions

American Journal of Respiratory and Critical Care Medicine
Abstract Introduction: Children exhibit heightened susceptibility to tuberculosis (TB), a disease caused by Mycobacterium tuberculosis (MTB) infection. Among the interferon-gamma release assays (IGRAs) recommended by the World Health Organization (WHO) for MTB infection screening is the newly included QuantiFERON-TB Gold Plus (QFT ...
