Filter by:The goal of this clinical trial is to determine whether vitamin D supplementation reduces risk of acquiring latent tuberculosis infection (LTBI) in school age children in Mongolia. The investigators hypothesize that (1) vitamin D supplementation will reduce risk of acquisition of LTBI, (2) vitamin D supplementation will safely reduce risk of developing active TB and improve other secondary efficacy outcomes, and (3) children with the lowest vitamin D status at baseline will gain most from the intervention.
The purpose of this study is to describe the medical indication and utilization of expert medical consultation among participants treated with bedaquiline (BDQ), BDQ susceptibility based on minimum inhibitory concentrations (MICs) reported for baseline and subsequent isolates, BDQ drug utilization data to include dose, duration, past treatment history, past medical history, concomitant medications, and health care site of treatment, drug distribution mechanisms used in the administration of BDQ, patient outcomes (clinical and microbiologic) and adverse events among BDQ-treated participants, including deaths.
Phase III trial evaluating raltegravir as an alternative to efavirenz for antiretroviral treatment of HIV-infected patients with tuberculosis.
To compare the results of the investigational test to the currently approved QuantiFERON-TB Gold In-Tube test.
Assess the mycobactericidal activity of PA-824 (given at 200 mg daily) when added to first-line tuberculosis (TB) treatment (isoniazid, pyrazinamide, and a rifamycin antibiotic) over 12 weeks of treatment. Funding Source - FDA Office of Orphan Products Development (OOPD)
To compare the results of the investigational test to the currently approved QuantiFERON-TB Gold In-Tube test.
Assess sensitivity and specificity of two nucleic acid amplification tests, namely Epistem Genedrive® and MolbioTruenat™ in raw sputum compared to the WHO-endorsed GeneXpert® MTB/RIF assay using a gold standard of four cultures
Consenting adults will be interviewed for demographic and medical information, and then will be asked to provide two expectorated sputum specimens. In the study laboratory, sputa will be tested using conventional and investigational diagnostic tests for tuberculosis.
Drug resistant tuberculosis is a growing problem world wide. The current methods for diagnosis are time consuming and may delay diagnosis and treatment for many weeks. In this study the investigators wish to take sputum samples from patients to see if the investigators can validate a molecular DNA based process for prompt identification of drug resistant tuberculosis. The investigators wish to extract and amplify DNA from drug resistant tuberculosis and identify genes within it that confer resistance.
The primary focus of this intervention trial is to understand the effect of quitting smoking on TB treatment outcomes. The investigators will compare a cessation strategy based on guidelines recommended by the World Health Organization (WHO) and the International Union against Tuberculosis and Lung Disease (IUTLD). This is currently not utilized in TB directly observed therapy (DOT) clinics in Pakistan. The investigators study will provide comprehensive data towards understanding the effectiveness of these strategies for TB patients who smoke in Pakistan, and most importantly, on the effect of quitting smoking on TB treatment outcomes. These findings will guide development of effective smoking cessation strategies in a region with high prevalence of TB and increasing tobacco use.
