NCT ID: NCT04048018 Recruiting - Clinical trials for Latent Tuberculosis Infection

Performance Evaluation of the VIDAS TB-IGRA Assay.

Start date: December 5, 2019
Study type: Observational

This study will evaluate the performance of the VIDAS® Interferon Gamma (IFN-γ) Release Assay (TB-IGRA) assay, which is intended for use as an aid in the diagnosis of tuberculosis infection. This study is designed to assess (1) the sensitivity of this assay, (2) its percent agreement with other diagnostic tests, (3) its measurement precision , and (4) any potential interference of the presence of other non-tuberculosis mycobacterial bacterial infections with this assay.

NCT ID: NCT03271567 Completed - Clinical trials for Tuberculosis, Pulmonary

Nanodisk-MS Assay for the Diagnosis of Active Pulmonary and Extrapulmonary Tuberculosis in Hospitalized Patients

Start date: September 28, 2017
Study type: Observational

Diagnosis and treatment of tuberculosis are often delayed in hospitalized patients, leading to worse outcomes. Rapid diagnosis of tuberculosis currently relies on microscopy and molecular techniques, which have limitations including low sensitivity and high cost.Highly sensitive diagnostic technique is needed for more accurate rapid diagnosis of tuberculosis to aid earlier initiation of antituberculous therapy. Detection of Mycobacterium tuberculosis (MTB) antigens in the bloodstream can potentially allow early diagnosis of tuberculosis. This study aims to evaluate the diagnostic performance of a novel assay using nanotechnology to detect MTB antigens in patients admitted to hospital with suspected pulmonary and/or extrapulmonary tuberculosis. Blood will be taken from eligible patients, and will be sent to the School of Biological and Health Systems Engineering, Arizona State University, for detection of 10-kDa culture filtrate protein (CFP-10) and the 6 kDa early secretory antigenic target (ESAT-6), two antigens specific for MTB, using the Nanodisk-MS assay. Investigations, including microscopy, culture, MTB polymerase chain reaction (PCR), and imaging, will be performed for diagnosis of tuberculosis. The diagnostic performance of Nanodisk-mass spectrometry (MS) assay will be evaluated.

NCT ID: NCT02898623 Recruiting - Active Tuberculosis Clinical Trials

Serological Test for the Diagnosis of TB

Start date: December 2013
Phase: N/A
Study type: Observational

TB remains a health problem in France with about 5,000 new cases per year. Development of new screening tests is a priority for TB. The main objective of the study is to evaluate performances of innovative blood tests to identify active tuberculosis in adults patients living in low-prevalence country. Adult patients with possible TB from will be tested for the presence of antibodies directed against M. tuberculosis selected antigens. Positive and negative predictive values will be established based on TB culture results.

NCT ID: NCT02639936 Recruiting - Active Tuberculosis Clinical Trials

New Generation IGRA in Immunocompromised Individuals

Start date: December 2015
Phase: N/A
Study type: Observational

Evaluation of a new ELISA based interferon-gamma release assay (QuantiFERON TB plus In-tube test) in immunocompromized patients

NCT ID: NCT02512484 Not yet recruiting - Latent Tuberculosis Clinical Trials

Improving the Detection of Active Tuberculosis in Accident and Emergency Departments

Start date: May 2016
Phase: N/A
Study type: Observational

Tuberculosis (TB) control remains a public health challenge. Many people in the UK do not have a general practitioner (GP) registration and their only interaction with the NHS is via Accident and Emergency (A&E) Departments of hospitals. This is often the case for those in hard to reach groups, who are also those often at highest risk of TB. This study seeks to assess whether A&E Departments are effective sites for the identification and onward management of TB, both in its latent and active forms.

NCT ID: NCT02042261 Completed - Active Tuberculosis Clinical Trials

The Role of Therapeutic Drug Monitoring in Tuberculosis - a Pilot Study

Start date: January 2012
Phase: N/A
Study type: Observational [Patient Registry]

Drug resistant TB is increasing and in order to enchance the efficacy of the current drugs, individualized therapy using plasma drug concentrations and minimal inhibitory concentration (MIC) determination may be of importance. This concept is defined as therapeutic drug monitoring (TDM). In this pilot study our hypothesis is that the ratio between MIC and drug concentration data is correlated to the bacterial load measured as time to positive liquid culture (TTP). In two sites in Sweden (Linköping and Karolinska Hospital Solna, Stockholm), 25 patients with pulmonary tuberculosis will be recruited. MIC-determination of Mycobacterium tuberculosis will be performed in BACTEC 960 MGIT and drug concentration will be determined at 2, 4 and 12 weeks after treatment initiation using LC-MS/MS methodology. Sputum cultures will be obtained at 0, 2 days, 7 days, 2 weeks, 4 weeks and 8 weeks and TTP will be measured in duplicate samples. Clinical follow up according to WHO criteria will be performed 1 year after completion of treatment.

NCT ID: NCT01269268 Completed - Active Tuberculosis Clinical Trials

Characterization and Evaluation of Diagnostic Biomarkers for Tuberculosis

Start date: June 2010
Study type: Observational

There was no sensitive and specific biomarker for tuberculosis infection, disease progression and predicting the prognosis of treatment. Therefore, the investigators aimed to investigate and evaluate the newer biomarker for the diagnosis of TB infection. To investigate the new biomarker for TB infection, the investigators will recruit the participants including active TB patients, healthy household contacts, healthy community control.
