Active clinical trials for "Tuberculosis"

Specimen transport from peripheral health structures to the National TB reference laboratory for MDR-TB identification presents a big challenge in term of sample management, safety, contamination and delays. Thus a system that allows specimen to be collected and shipped in a safely manner while reducing the possibilities of contamination, the cost of shipment and especially the time for detection of MDR-TB by using molecular methods would be very useful. Whereas the some studies show promising results for the development and standardization of simple specimen collection and transportation methods for molecular DST, more data is needed before these can be used in routine. The study described here aims at identifying a suitable method, in terms of adapted sample support (s) (slide, filter paper (FTA, Genocard ...)) and DNA extraction method. If one or several methods are found to give satisfying results, then a larger patient based evaluation of this (these) method(s) for molecular DST will be performed in a second phase. The protocol for the second phase will be prepared separately.

It is clinically challenging to differentiate Crohn's disease from gut tuberculosis especially in regions endemic of tuberculosis infection. The investigators plan to perform magnetic resonance enterography (MRE) who presented to our hospital in Shenzhen, China for new onset of lower gastrointestinal symptoms and ileocecal mucosal lesions of uncertain diagnosis as evidenced by the presence of inflammation, ulceration, strictures or nodules on colonoscopy. MRE findings will be independently interpreted by two radiologistsThe role of MRE in distinguishing gut tuberculosis from Crohn's disease will be determined.

Background: Many people around the world get tuberculosis (TB) and non-tuberculous mycobacteria (NTM) infections. Sometimes medicine that treats these infections does not get to where the bacteria are in the lungs. Researchers want to find a way to tell if enough medicine is getting to where it is needed in the lungs. They will look at how much medicine is in your sputum (what you cough up) compared to how much is in your blood. They will also investigate a new test to quickly figure out what medicines are likely to treat TB effectively. Objective: To determine the relationship between the concentration of TB drugs in plasma and sputum over time. Eligibility: People ages 18 and older who have TB or NTM infection that is suspected to be drug resistant. They must be taking TB or NTM medicines. Design: Participants will be screened with medical history. Participants will be in the study for 2 8 days. Participants will give 3 or more sputum samples over at least 2 different days. They will cough sputum into a cup. Participants will have blood drawn 4 times a day on 2 different days.

P1106 is Phase IV prospective pharmacokinetic (PK) study of low birth weight infants who are receiving or will be receiving as part of clinical care nevirapine (NVP) prophylaxis, tuberculosis (TB) prophylaxis or treatment and/or combination antiretroviral (ARV) treatment containing lopinavir/ritonavir (LPV/r). The study is designed to describe the pharmacokinetics and safety of NVP, INH, RIF, and LPV/r in these infants receiving the drug(s) as part of clinical care.

The SEARCH study aims to test evidenced-based innovative community based interventions that lead to the elimination of HIV in rural communities in East Africa using a multi-disease approach. The first phase of the study will quantify the impact of early HIV diagnosis using a streamlined and immediate ART (antiretroviral therapy). The second phase of the study, will quantify the impact of targeted Pre-Exposure Prophylaxis (PrEP) in the context of universal treatment and streamlined care. The study intervention is designed to improve the entire continuum of care, to reduce structural barriers for all populations including those most "at risk".

The overall research objective is to evaluate the impact of implementing a reminder system for medical providers to improve TB case-finding and isoniazid preventative therapy (IPT) for adults living with HIV in western Kenya

The purpose of this study is to examine the colchicine concentration before and after the administration of rifampicin.

The goal of this study is to evaluate time to diagnosis for three assays (line probe, pyrosequencing, and Microscopic Observation Drug Susceptibility Assay [MODS]) to detect resistance to first and second-line anti-tuberculosis (TB) drugs in Mycobacterium tuberculosis (Mtb) strains in 7 days or less, allowing for rapid diagnosis of extensively drug-resistant TB (XDR-TB).

The purpose of this study is to determine the effectiveness and cost-effectiveness of a new population-based active case-finding program among adult household contacts of new infectious TB cases to detect active TB cases in the largest district, Lima, Peru.

The purpose of this study was to determine the prevalence of latent tuberculosis infection among injecting drug users and to conduct randomized controlled trial to evaluate a case management intervention aimed at increasing TB screening and treatment entry among injecting drug users referred from a methadone drug treatment program in Estonia.
