Association of age with the level of response in the QuantiFERON-TB Gold In-Tube assay for children with active tuberculosis.

چکیده
QuantiFERON-TB data from 50 children with tuberculosis were analysed to evaluate age related effects. Significantly higher IFN-? responses to TB-specific antigens were associated with younger age, but no difference was found with Mitogen responses. Extrapolating IGRA responses to a Mitogen does not reflect those induced by an antigen-specific stimulus. QFT-IT responses to TB-specific antigens are not compromised with young age.

QuantiFERON-TB Gold and Tuberculin Skin Test for the Diagnosis of Latent Tuberculosis Infection in Children
Background: Appropriate diagnosis and treatment of latent tuberculosis infection (LTBI) play the most important role in the control of tuberculosis. This study aimed to determine the prevalence of LTBI among healthy tuberculosis unexposed children vaccinated with BCG using the tuberculin skin test (TST) and QuantiFERON TB Gold In-Tube (QFT-GIT) and comparing the agreement between the two tests....
متن کاملFluctuating Behavior and Influential Factors in the Performance of the QuantiFERON-TB Gold In-Tube Assay in the Diagnosis of Tuberculosis
BACKGROUND The QuantiFERON-TB Gold In-Tube (QFT-GIT) is a newly developed but widely used interferon-γ release assay for diagnosing tuberculosis (TB). However, research has not determined whether age or the use of an immune suppressive or anti-TB treatment influences this assay's ability to detect TB. We assessed the QFT-GIT diagnostic performance for active tuberculosis (ATB) in children and a...
