Filter by:This is a doble-blind, masked, compared with placebo clinical trial in pediatric population in contact with tuberculosis with or without tuberculosis infection. This trial aims to study the effect of the probiotic Nyaditum resae® at the level of specific Treg memory cells eight weeks after the first administration, and the global tolerability of the treatment. Nyaditum resae® is a preparation in the form of capsules containing heat-killed environmental mycobacteria Mycobacterium manresensis. The overall objective of the study is the effect of Nyaditum resae® on immunity, which could reduce the risk of developing active tuberculosis.
In this trial, the investigators are assessing whether giving an increased dose of rifampicin to patients receiving the standard treatment for tuberculosis is safe and, when given for 4 months only, will also result in greater and faster killing of the tubercle bacillus in the lungs and result in relapse rates similar to those found in the World Health Organisation (WHO) recommended standard 6 month regimen.
A phase 2, multicenter, uncontrolled, open-label trial in participants with Multi-drug Resistant Tuberculosis (MDR-TB). Only participants who completed Trial 242-07-204 (NCT00685360) were eligible. The trial was performed globally at 14 sites qualified to treat MDR-TB. All 434 participants who completed Trial 242-07-204 were eligible for this trial if there was still potential clinical benefit to them and all inclusion criteria and no exclusion criteria were met.
Brazil ranks 17th among the 22 countries responsible for 80% of tuberculosis (TB) cases in the world. In 2010, the number of new cases of tuberculosis in Brazil was 71,930 and in 4972 RS. In 2010, Brazil had a disease incidence of 37.6 / 100,000 in 2011 fell to 36.0 / 100,000. The Rio Grande do Sul(RS)S showed an incidence rate of 46.1 / 100,000 in 2011. The mortality rate was 2.4 / 100,000 population per year in Brazil and RS. In Porto Alegre, the incidence rate of all clinical forms of tuberculosis has remained, in the last six years, around 100/100.000 inhabitants per year, while the coefficient of pulmonary tuberculosis remained on average 50/100.000 inhabitants to year. Thus, Porto Alegre holds the 2nd place in Brazil among the capitals with the highest incidence of TB, classifying the city as high risk 5th. Porto Alegre also has a co-infection TB / HIV from 35.3% one of the highest in the country. The best strategy to prevent new cases of tuberculosis is to invest in early diagnosis and effective treatment of existing cases of the disease. As the treatment of the disease requires daily use of medications for an extended period of time (at least 6 months), adherence becomes the main determinant of the rate of healing of disease. There are several factors that contribute to poor adherence and treatment dropout: alcoholism, illicit drug use, infection with human immunodeficiency virus (HIV Human Immunodeficiency Virus), low education, unemployment, poor housing and prolonged the treatment. The irregular treatment and neglect are the major obstacles to the control and elimination of this disease. Study in Porto Alegre pointed alcoholism, TB / HIV, the fact that the patient does not reside with family and low education as predictors of dropout. The dropout rate in the general population of patients with active tuberculosis was 10.7% (8.0% - 17.0%). Abandonment occurred more often within the first three meses8. In Porto Alegre, 32.5% of new TB cases are diagnosed in hospitals. Twenty percent of these patients do not bind, after discharge, the Tuberculosis Control Program (TCP), ie, the patient egress from the hospital does not reach the basic health unit (BHU) reference for further monitoring and treatment, which is considered a serious flaw in the process control of the disease.
Tuberculosis (TB) patients often have a lower body mass index (BMI) and experience wasting. Wasting reduces lean body mass and may cause physical function impairment. This study aimed to determine the efficacy of fermented soybeans (tempeh) as a food supplement on body weight and physical function changes among active pulmonary tuberculosis patients with standard therapy.
Background: In Botswana, as in the rest of sub-Saharan Africa, undiagnosed TB or TB diagnosed late in the course of disease is thought to be the most common cause of death among HIV-infected persons. Interventions for Evaluation: The Xpert MTB/RIF assay for the GeneXpert platform (Xpert) has a TB diagnostic sensitivity of 82.4%, significantly superior to that of smear microscopy (44.6%). In line with WHO guidelines, the Botswana Ministry of Health (MOH) and CDC rapidly rolled out the Xpert device and a new Xpert-based diagnostic algorithm in service of 22 HIV care and treatment clinics. To maximize impact of the Xpert device in improving detection of active TB, Xpert rollout was preceded by strengthening of TB screening procedures by: (1) adopting the WHO-recommended 4-symptom TB screen for adults; (2) situating trained TB case-finding nurses in facilities; and (3) training health facility personnel in TB diagnostic algorithms. The combination of these strengthened TB screening procedures and rollout of the Xpert device is referred to as the "Xpert package" in this protocol. Key Evaluation Objectives: The protocol has two key objectives: (1) to evaluate whether the new MOH-recommended Xpert-based TB diagnostic algorithm for new adult HIV clinic enrollees is more sensitive than the pre-Xpert smear-microscopy-based algorithm in diagnosing culture-positive TB disease; and (2) to evaluate the impact of the whole "Xpert package" on all-cause mortality during the first 6 months of ART, among adult patients. Design: Stepped-wedge cluster randomized trial. Sample Size: 6,136 patients were prospectively enrolled to meet the first primary objective. A retrospective cohort of 10,131 persons was also enrolled to meet the second objective. Projected power to meet both objectives is >80%. Time line: Prospective cohort enrollment started in July 2012 and was complete by March 2014. Retrospective cohort enrollment was complete by March 2015. Patient follow-up and data entry will be complete in March 2016 at which time analysis to answer the first two primary study questions will be possible.
NOTE THAT THE STUDY IS LED BY SOUTH AFRICA NATIONAL DEPARTMENT OF HEALTH AND WORLD BANK WITH SUPPORT FROM BOSTON UNIVERSITY. The South Africa National Department of Health (NDOH) intends to launch its newly developed National Adherence Guidelines for Chronic Diseases (HIV, TB and NCDs) throughout South Africa in the coming year. Early implementation of the "minimum package" of interventions described in the Adherence Guidelines for HIV patients will take place at 12 primary health clinics and community health centres in four provinces starting in July 2015. To maximize the learning potential of this early implementation stage, NDOH will match the intervention clinics with 12 comparison clinics and randomly allocate intervention or comparison status within the pairs of clinics. This will allow the outcomes of the interventions to be evaluated using a cluster-randomized design and generate data on the costs of implementation and the potential need for adherence support for the other diseases addressed in the guidelines (tuberculosis, hypertension, and diabetes). This protocol is for the evaluation, which will generate information on the effectiveness of minimum package interventions and help improve the design, implementation, and budgeting of the guidelines.
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.
Task shifting of less complex healthcare tasks to lay health workers (LHWs) is increasingly employed strategy to address the global shortage of skilled health workers. Despite availability of effective treatment, tuberculosis (TB) remains an important cause of mortality with 1.3 million lives lost globally to TB in 2012. The greatest proportion of new TB cases occurs in Africa and over 95% of TB deaths occur in low income countries (LICs). In response to the combined high TB burden and severe healthcare worker shortages in these settings, outpatient TB care is among the tasks commonly shifted to LHWs. LHWs are community members who have received some training but are not healthcare professionals. Randomised trials show LHWs improve access to basic health services and TB treatment outcomes, however, insufficient training and supervision are recognized barriers to their effectiveness. The investigators' goal is to improve TB care provided by LHWs in Malawi by implementing and evaluating a knowledge translation (KT) strategy designed to facilitate incorporation of evidence into LHW practice. The investigators will employ a mixed methods design including a pragmatic cluster randomized controlled trial to evaluate effectiveness of the strategy and qualitative methods to understand barriers and facilitators to scalability and sustainability of the program.
Pregnant women who develop active Tuberculosis (TB) are at increased risk of poor maternal and infant outcomes. Our data from South Africa show that up to 3% of HIV-infected pregnant women have active TB , many with advanced disease, contributing to the 40% of maternal mortality associated with TB or HIV in South Africa . Screening for TB in pregnant women in this setting is therefore essential to reduce maternal mortality. Symptom-directed screening for TB has been recommended by the World Health Organization and by the South African National Department of Health; however, no implementation framework is in place to operationalize the guidelines. Symptom-based testing is an efficient process that limits use of diagnostic tests, but may miss many cases. In Soweto, we found that 0.7% (700/100,000) of HIV-infected women had active TB when a symptom-based strategy was employed once, but in Klerksdorp we found that 3.3% (3,300/100,000) had active TB when universal testing, regardless of symptoms, was performed; most TB cases were newly diagnosed among women who reported no symptoms .
