Interferon gamma releasing assay(IGRA) is useful to diagnose latent tuberculosis. However,IGRA responses could show within-subject variability. We wanted to determine long-term IGRA variability in health-care workers who continuously expose to tuberculosis patients.
IGRA will be performed monthly in health-care workers with continuous exposure to tuberculosis patients for 1 year.

The purpose of this study is to measure alpha-synuclein in peripheral body tissues and fluids in Parkinson's disease (PD). This may help in developing better treatments for PD patients in ...
The purpose of this study is to gain a better understanding of how immunity to tuberculosis (TB) is maintained in children. When children get tuberculosis, it is more likely to spread to o...
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 ...
New blood tests have become available to detect either latent or active tuberculosis. These tests - which according to the CDC can replace the tuberculin skin test - measure the production...
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...
HIV-1 infection substantially increases the risk of developing tuberculosis (TB). There is extensive depletion of Mycobacterium tuberculosis (M.tuberculosis)-specific CD4+ T cells in blood in early HI...
Tuberculosis (TB) remains one of the leading causes of morbidity and mortality worldwide. The primary method for controlling TB is the rapid and accurate identification of infected individuals. Immune...
Blood based Interferon-(IFN)-γ release assays (IGRAs) have a poor predictive value for the development of tuberculosis. This study aimed to investigate the correlation between IGRAs and pulmonary imm...
We validated the accuracy of host selected signature gene set using unstimulated whole blood (WB), and peripheral blood mononuclear cells (PBMC) in the diagnosis of tuberculosis (TB).
Therapeutic drug monitoring is useful in the treatment of tuberculosis to assure adequate exposure, minimize antibiotic resistance, and reduce toxicity. Salivary therapeutic drug monitoring could redu...
Pathological conditions of the CARDIOVASCULAR SYSTEM caused by infection of MYCOBACTERIUM TUBERCULOSIS. Tuberculosis involvement may include the HEART; the BLOOD VESSELS; or the PERICARDIUM.
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.
An acute form of TUBERCULOSIS in which minute tubercles are formed in a number of organs of the body due to dissemination of the bacilli through the blood stream.
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)
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.
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. ...
