Longitudinal Assessment of an ELISPOT Test for Mycobacterium tuberculosis Infection
BACKGROUND Very little longitudinal information is available regarding the performance of T cell-based tests for Mycobacterium tuberculosis infection. To address this deficiency, we conducted a longitudinal assessment of the enzyme-linked immunosorbent spot test (ELISPOT) test in comparison to the standard tuberculin skin test (TST). METHODS AND FINDINGS In tuberculosis (TB) contacts we repea...
متن کاملCan ELISpot replace the tuberculin skin test for latent tuberculosis?
BACKGROUND Screening and treatment of latent tuberculosis infection (LTBI) prior to anti-tumour necrosis factor alpha (anti-TNF-alpha) therapy has been shown to decrease the incidence of active tuberculosis (TB) by more than 80%, and is recommended by the British Thoracic Society. In the absence of a gold standard test for LTBI, conventional screening currently involves taking a clinical histor...
متن کاملDistinguishing Latent from Active Mycobacterium tuberculosis Infection Using Elispot Assays: Looking Beyond Interferon-gamma
Mycobacterium tuberculosis (MTB) is a global heath epidemic, its threat amplified by HIV infection and the emergence of multidrug-resistant tuberculosis (MDR-TB). Interferon (IFN)-gamma release assays (IGRAs) have improved the accuracy of detection of MTB exposure in some subject groups as compared to the Tuberculin Skin Test (TST). However, as IFN-gamma is produced by both fully rested and mor...
متن کاملLatent Mycobacterium tuberculosis Infection.
To the Editor: In their review article, Getahun et al. (May 28 issue)1 provide a useful overview of issues surrounding latent tuberculosis infection. However, newly published data regarding the performance of the T-SPOT.TB assay call into question the supposition that false conversions and reversions are more common with interferon-γ release assays (IGRAs) than with tuberculin skin tests.2 Spec...
متن کاملQuantiFERON-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....
