Interferon-Gamma Release Assays versus Tuberculin Skin Testing for the Diagnosis of Latent Tuberculosis Infection: An Overview of the Evidence

Pulmonary Medicine, 2013
A profusion of articles have been published on the accuracy and uses of interferon-gamma releasing assays. Here we review the clinical applications, advantages, and limitations of the tuberculin skin test and interferon-gamma release assays and provide ...

Cost-effectiveness of Interferon Gamma Release Assays vs Tuberculin Skin Tests in Health Care Workers [PDF]

Archives of Internal Medicine, 2009
Interferon gamma release assays (IGRAs) offer alternatives to tuberculin skin tests (TSTs) for diagnosing latent tuberculosis infection (LTBI). Unlike TSTs, IGRAs require only a single patient visit and are not affected by prior BCG vaccination, providing greater specificity.

Latent tuberculosis infection prevalence in second generation immigrants from high to low TB burden countries

Pulmonology, 2023
Background Latent tuberculosis infection (LTBI) diagnosis in a country with a low tuberculosis burden is complicated. Since the prevalence of LTBI in second generation immigrants has not been well recognized, we conducted a cross-sectional study which ...

Diagnosis of latent Mycobacterium tuberculosis infection: tuberculin test versus interferon-gamma release [PDF]

Revista da Sociedade Brasileira de Medicina Tropical, 2015
The treatment of individuals with active tuberculosis (TB) and the identification and treatment of latent tuberculosis infection (LTBI) contacts are the two most important strategies for the control of TB. The objective of this study was compare the performance of tuberculin skin testing (TST) with QuantiFERON-TB Gold In TUBE(r) in the diagnosis of ...

Hemodialysis acutely altered interferon-gamma release assay test result and immune cell profile

Journal of Microbiology, Immunology and Infection, 2022
Patients receiving hemodialysis (HD) are at risk of TB development. IGRA-positive patients showed significant decrease in quantitative IGRA result with alterations in CD3+CD4+CD45RO+, NK cell, and monocyte subsets immediately upon HD procedure. Our result suggested that the timing of IGRA testing is crucial in end-stage renal disease population.

Interferon-γ acutely augments inhibition of neocortical layer 5 pyramidal neurons [PDF]

, 2020
BACKGROUND: Interferon-γ (IFN-γ, a type II IFN) is present in the central nervous system (CNS) under various conditions. Evidence is emerging that, in addition to its immunological role, IFN-γ modulates neuronal morphology, function, and development in ...

Performance of commerical blood tests for the diagnosis of latent tuberculosis infection in children and adolescents [PDF]

, 2009
BACKGROUND: The accurate diagnosis of latent tuberculosis infection reduces the risk of progression to severe disseminated disease. However, in young children, a major limitation of the standard tuberculin skin test is that false-negative results cannot ...
