The objective is to achieve 90% overall, positive and negative clinical concordance between results of the T-SPOT.TB assay, using cells isolated via density gradient centrifugation and positive selection using the T-Cell Select kit, between 0-55 hours following venepuncture
In this study, clinical concordance between results of the T-SPOT.TB assay, using cells stored for 0-8 hours post venepuncture and isolated via density gradient separation and positive selection with magnetic bead isolation using the T-Cell SelectTM Kit will be assessed. Concordance between results of the T-SPOT.TB assay at 0-8 hours post venepuncture and using cells isolated with density gradient centrifugation and results obtained from cells isolated using the T-Cell Select Kit, following storage between 0-55 hours post venepuncture, will be assessed.

Diagnosis of active and latent pulmonary tuberculosis, as well as extrapulmonary tuberculosis, is still a major challenge of TB control in China. This observational study aims to evaluate ...
This was a clinical trial in HIV infected patients with tuberculosis. The study assessed whether the addition of prednisolone, a type of steroid medication, to the standard treatment for t...
HIV induced altered representation and function of regulatory T cell subsets (NKT and Treg cells) impair the protective T cell response against M.tuberculosis and disrupts LTBI, thus facil...
Tuberculosis is a major cause of mortality among AIDS patients in the developing world. The diagnosis of tuberculosis in HIV infected children is complicated by inefficient and expensive ...
The purpose of this study is to assess lung immune responses in patients with active pulmonary tuberculosis (TB) and in healthy control persons who are exposed to Mycobacterium tuberculosi...
Tuberculosis meningitis (TBM) is one of the most severe forms of tuberculosis. However, TBM diagnosis is quite challenging due to nonspecific clinical presentation and the paucity of the pathogen in c...
Mycobacterium tuberculosis DNA has been detected in multiple organs in people without active tuberculosis or a history of tuberculosis. Molecular testing for metabolic activity has suggested that M. t...
DAR-901 is an inactivated whole cell tuberculosis booster vaccine, prepared using a new scalable, broth-grown method from the master cell bank of SRL172, a vaccine previously shown to prevent tubercul...
Whether T-cell interferon-γ responses to Mycobacterium tuberculosis-specific antigens can be influenced by tuberculosis preventive treatment in a high-endemic country is uncertain.
Urogenital tuberculosis is still a frequent presentation, and it constitutes a current public health problem in endemic areas. The clinical presentation of this form of the disease may be misleading. ...
The dormant form of TUBERCULOSIS where the person shows no obvious symptoms and no sign of the causative agent (Mycobacterium tuberculosis) in the SPUTUM despite being positive for tuberculosis infection skin test.
Tuberculosis of the brain, spinal cord, or meninges (TUBERCULOSIS, MENINGEAL), most often caused by MYCOBACTERIUM TUBERCULOSIS and rarely by MYCOBACTERIUM BOVIS. The infection may be limited to the nervous system or coexist in other organs (e.g., TUBERCULOSIS, PULMONARY). The organism tends to seed the meninges causing a diffuse meningitis and leads to the formation of TUBERCULOMA, which may occur within the brain, spinal cord, or perimeningeal spaces. Tuberculous involvement of the vertebral column (TUBERCULOSIS, SPINAL) may result in nerve root or spinal cord compression. (From Adams et al., Principles of Neurology, 6th ed, pp717-20)
Pathological conditions of the CARDIOVASCULAR SYSTEM caused by infection of MYCOBACTERIUM TUBERCULOSIS. Tuberculosis involvement may include the HEART; the BLOOD VESSELS; or the PERICARDIUM.
TUBERCULOSIS that involves any region of the GASTROINTESTINAL TRACT, mostly in the distal ILEUM and the CECUM. In most cases, MYCOBACTERIUM TUBERCULOSIS is the pathogen. Clinical features include ABDOMINAL PAIN; FEVER; and palpable mass in the ileocecal area.
Tuberculosis of the mouth, tongue, and salivary glands.
An assay is an analytic procedure for qualitatively assessing or quantitatively measuring the presence or amount or the functional activity of a target entity. This can be a drug or biochemical substance or a cell in an organism or organic sample. ...
