Filter by:Tuberculosis (TB) whole genome sequencing (WGS) allows outbreak identification and disease transmission tracking. It is hypothesized that prospective WGS-guided epidemiological investigations improve case detection compared to current best practices by adapting contact tracing strategies to local transmission patterns. A cluster randomized controlled trial (cRCT) will be performed in high TB incidence villages of Haute Matsiatra region in Madagascar. Communities will be randomized in three separate TB control strategies comparing (1) standard of care, (2) the World Health Organization (WHO) recommended best practices and (3) a novel intervention involving TB WGS cluster-guided epidemiological investigations. The incremental value of TB WGS on case notifications and reduction of TB burden will be measured. Secondary studies will be nested within this cRCT will include: - A qualitative study which will increase the understanding of the factors facilitating and hindering implementation of WGS-based diagnostics within health systems. - A cost effectiveness analysis study which will measure the cost effectiveness of newly implemented laboratory methods. Field and genomic epidemiology data from this project will inform future work on the design of community-level TB elimination strategies in collaboration with Madagascar National TB program
Tuberculosis (TB) remains the most important infectious disease in the world. A major barrier to tuberculosis control is poor adherence to long-term and complex treatment regimens. This is a multicenter prospective, non-inferiority randomized controlled study. The purpose of our study is a) to evaluate the tolerability, efficacy and pharmacokinetics/pharmacodynamics (PK/PD) of the high-dose rifapentine, b) to evaluate whether the high-dose rifapentine-containing regimen has the potential to treat the rifampicin-sensitive pulmonary tuberculosis and shorten the course of treatment to 17 weeks. This study is of great significance for shortening the course of treatment, reducing the adverse reactions and economic burden of patients' treatment in rifampicin-sensitive tuberculosis patient.
Primary objective of the trial is to study the safety and tolerability of the Recombinant tuberculosis allergen in standard dilution in healthy volunteers after a single dose. Additional trial purpose: evaluation of the product reactogenicity.
Tuberculous pleuritis (TBP) is the most common manifestation of extrapulmonary TB. Its diagnosis is challenging due to the low sensitivity of mycobacterial culture from the pleural fluid and the need for invasive pleural biopsy. Preliminary data has shown the superior sensitivity of Mycobacterium tuberculosis cell-free DNA (MTB cfDNA) to conventional culture and MTB polymerase chain reaction (PCR), but the cutoff level of MTB cfDNA was not determined. This study involves a prospective collection of pleural fluid due to TBP and non-TBP aetiologies, with subsequent testing by MTB culture, MTB cfDNA and MTB PCR. The levels of MTB cfDNA in the pleural fluid will be correlated with different types of diagnosis, and its diagnostic accuracy will be compared with conventional culture and MTB PCR. A confirmatory study result of MTB cfDNA can shorten the time to diagnosis, reduce the need for pleural biopsy and prevent the delay of definitive treatment.
To evaluate the 2-week bactericidal activity, pharmacokinetics, safety and tolerability of sanfetrinem cilexetil in participants with rifampicin-susceptible pulmonary tuberculosis.
The purpose of this study is to compare a 6-month regimen of high-dose rifampicin (RIF), high-dose isoniazid (INH), linezolid (LZD), and pyrazinamide (PZA) versus the World Health Organization (WHO) standard of care (SOC) treatment for tuberculosis meningitis (TBM).
This study aims to measure the early bactericidal activity (EBA), safety, tolerability and pharmacokinetics with GSK3036656 in combination with either delamanid or bedaquiline or BTZ-043, delamanid in combination with bedaquiline or standard of care for 14 days in participants with newly diagnosed sputum smear positive drug-sensitive pulmonary tuberculosis. Participants will revert to the standard treatment (RIFAFOUR® e-275) once the study treatment (Day 1 to Day 14) has been completed.
The objective of this study is to analyze the efficacy of a new regimen using Bedaquiline, Pretomanid, Linezolid, and Moxifloxacin for 24 weeks or Bedaquiline, Pretomanid, Linezolid for 26 weeks for the treatment of MDR/RR-TB through the clinical trial.
Background : The toll-like receptor is an essential receptor that stimulates the innate immunity response. In tuberculosis, toll-like receptors, particularly the TLR-2, and TLR-4 are crucial in recognizing various ligands with a lipoprotein structure in the bacilli. Vitamin D deficiency leads to lower expression of these receptors, Hence the immune response against Mycobacterium tuberculosis will be altered. Various studies addressed the importance of vitamin D supplementation in pulmonary tuberculosis but the effect of vitamin D in extrapulmonary tuberculosis, particularly spondylitis tuberculosis is not sufficiently identified. Objectives: To assess the effect of oral vitamin D supplementation on the expression of TLR-2, TLR-4, and clinical outcomes in spondylitis tuberculosis patients. Methodology: This study proposes a randomized clinical trial of oral vitamin D supplementation in spondylitis tuberculosis patients. Multiple arms will be established with different doses and control groups. The outcome of interest includes the clinical outcomes, the expression of TLR-2, and TLR 4 Hypothesis : It is assumed that oral supplementation of Vitamin D will increase the activation of Toll-Like Receptors and improves the clinical condition of Spondylitis Tuberculosis patients
Diagnosis of tuberculosis (TB) in children is particularly challenging in low and middle-income countries (LMIC), and a high number of children remain undiagnosed and untreated. A delay in diagnosis can lead to an increase in preventable morbidity and mortality. Point-of-care ultrasound (POCUS) is a bedside, non-invasive, inexpensive imaging tool, and TB-focused POCUS has been used and validated for adults with HIV. This study aims to describe the TB-focused POCUS findings for children with presumptive TB aged between 6 months and 15 years old, and to stratify the results per HIV, nutritional status and age. This is a Médecins Sans Frontières (MSF) multicentric study which takes place in Guinea Bissau and South Sudan.
