Filter by:A diagnostic validity study in which urinary LAM was done in seropositive HIV patients with symptoms suggestive of TB who were included and investigated with battery of tests to reach the final diagnosis.
PredictEndTB signature is a non-inferiority, prospective, parallel-group open-label randomized controlled trial evaluating the efficacy of individualised antituberculous treatment durations that utilize the transcriptomic signature-based model compared to the standardised twenty months treatment in a cohort of multidrug-resistant tuberculosis patients.
The ERASE - TB study will be conducted in order to fill a critical unmet need for tuberculosis control. Persons who are in contact with an infectious TB case may become infected themselves. Among those who are infected, most will stay healthy but some will develop TB themselves. These people would benefit from preventive treatment, which would also stop TB from being spread to other persons. The problem currently is that it is impossible to determine with certainty who would require preventive treatment, and who will remain healthy. Out of 100 persons exposed to an infectious TB patient, only 2 will go on to have TB according to a study in Vietnam, but there are no good tests available to identify those with a risk for TB disease. Treating 100 persons to prevent 2 cases of TB is not effective, so preventive treatment is not used in adults and adolescents in Tanzania, Mozambique and Zimbabwe, where this study will be conducted, but also in many other settings. The ERASE - TB project will evaluate a number of newly developed diagnostic tests, to see which of those will be able to predict TB in persons at risk, and therefore steer preventive treatment well. For this, the investigators will invite 2,100 household contacts (HHC) of infectious TB patients, who are at least 10 years old, into the study. Everyone will be examined initially, and again in regular intervals, for 1.5 to 2 years; and whenever the participants will present with symptoms that could indicate that they develop TB. At every visit, the investigators will perform an X-ray and take some blood and urine samples to perform new candidate tests. At the first/baseline visit, all household contacts without TB will undergo a spirometry to evaluate their pulmonary function. If someone is unwell, the investigators will also examine sputum for the presence of TB bacilli. In the end, the investigators will then be able to say who of the persons in the study developed TB, and who remained healthy. From all samples taken at different timepoints, the investigators will then determine which test found TB early, and clearly distinguished between persons developing TB, and persons who would remain healthy .
The purpose of this study is to evaluate the human clinical response to BCG challenge in historically BCG-vaccinated healthy adult volunteers. It will involve 12 participants in a controlled dose escalation. Bronchoscopies will be performed 14 days post-challenge to measure BCG recovered from bronchial samples. Blood tests will be taken to look at potential immunological markers of immunity.
The purpose of this study is to assess the safety of rifampicin given at a dose three times as the standard one, in persons with tuberculosis that belong to groups that have not been widely included in previous trials.
The purpose of the study is to compare the efficacy and safety of standard chemotherapy regimen 2HRZE/4HR plus IL-2 and standard regimen 2HRZE/4HR for newly diagnosed smear positive pulmonary tuberculosis.
The performance of a new triage test for active tuberculosis (TB), SeroSelectTB, will be qualified in multi-centre randomised controlled trials at health-posts in South Africa, Tanzania and Ethiopia. Cost effectiveness evaluations will be conducted to support a value proposition to stakeholders and regulatory authorities, and to support commercialization requirements. Consenting adults will provide blood and saliva samples for screening by SeroSelectTB, and sputum collected for routine TB diagnosis by the health services. Clinical and sociodemographic information will be collected. A reliable rapid test will make it possible to identify and selectively treat those with active TB at the local healthcare level. The expected impact includes accurate same-day diagnosis of patients with active TB, reduction of diagnostic delay and TB transmission, and diagnostic cost-savings for patients and healthcare systems in high TB-burden countries.
Stage 1 proposed study will provide evidence to support the use of twice-daily dose 50mg DTG in children (20-35kgs) co-treated with RIF. Note: An amendment has been added to include children from 3kgs and a dose of 10mg dispersible DTG
The World Health Organization's Global Tuberculosis Programme (WHO-GTB) issues evidence-informed guideline recommendations on tuberculosis (TB). These recommendations are used by decision-makers, guideline developers and other stakeholders. In an effort to improve the accessibility and usability of these recommendations, a new eTB catalogue of recommendations has been developed. This study aims to compare the accessibility of the new eTB catalogue to the earlier method of accessing recommendations directed through the general WHO website.
The presence of calcifications, which is a relatively common feature in intrathoracic lymph nodes, typically contributes to confer them a heterogeneous aspect during endosonographic B-mode examination, but their prevalence and a possible association between calcifications and metastatic involvement has never been systematically evaluated. We hypothesize that, in patients undergoing mediastinal diagnosis or staging of suspected/known lung cancer/intrathoracic malignancies, the prevalence of lymph node metastases is similar in calcified and non-calcified lymph nodes.
