Extended culture enhances sensitivity of a gamma interferon assay for latent Mycobacterium tuberculosis infection.
نویسندگان
چکیده
To test the hypothesis that prolonged culture would enhance the sensitivity of latent tuberculosis detection by a gamma interferon release assay, blood samples from 33 household contacts of Gambian tuberculosis patients were stimulated with Mycobacterium tuberculosis-specific antigens. After 24 h of culture, 66% were positive, compared to 93% after 6 days of culture.

Performance of a whole blood interferon gamma assay for detecting latent infection with Mycobacterium tuberculosis in children.
BACKGROUND The diagnosis of latent Mycobacterium tuberculosis (MTB) infection with a tuberculin skin test (TST) in children is complicated by the potential influence of prior exposure to Bacille Calmette Geurin (BCG) vaccination or environmental mycobacteria. A whole blood assay has recently been developed to quantitatively measure interferon gamma (IFN-gamma) production by lymphocytes specific...

Central nervous system tuberculosis remains a clinical diagnostic challenge. The ex vivo Mycobacterium tuberculosis-specific enzyme-linked immunospot assay (ELISPOT) is a novel assay for the rapid detection of M. tuberculosis-specific T-lymphocytes in the peripheral blood. However, when performed on peripheral blood, this assay cannot distinguish between active tuberculosis or latent tuberculos...

CONTEXT A recently developed whole-blood interferon gamma (IFN-gamma) assay based on stimulation with the Mycobacterium tuberculosis-specific antigens early secreted antigenic target 6 and culture filtrate protein 10 shows promise for the diagnosis of latent tuberculosis (TB) infection. OBJECTIVE To compare the tuberculin skin test (TST) and the whole-blood IFN-gamma assay in the diagnosis of...

A whole-blood interferon-gamma release assay (IGRA) is being evaluated for its potential to replace the tuberculin skin test (TST) for detecting Mycobacterium tuberculosis infection. To test the assay in a population in which tuberculosis is highly endemic and in another population that is representative of an urban United States population, 253 volunteers from Ethiopia and 175 volunteers from ...

BACKGROUND Mycobacterium tuberculosis (Mtb) infection may cause overt disease or remain latent. Interferon gamma release assays (IGRAs) detect Mtb infection, both latent infection and infection manifesting as overt disease, by measuring whole-blood interferon gamma (IFN-γ) responses to Mtb antigens such as early secreted antigenic target-6 (ESAT-6), culture filtrate protein 10 (CFP-10), and TB7...
