PET/CT guided tuberculosis treatment shortening: a randomized trial.

Six months of chemotherapy using current agents is standard of care for pulmonary, drug-sensitive tuberculosis (TB), even though some are believed to be cured more rapidly and others require longer therapy. Understanding what factors determine the length of treatment required for durable cure in individual patients would allow individualization of treatment durations, provide better clinical tools to determine the of appropriate duration of new regimens, as well as reduce the cost of large Phase III studies to determine the optimal combinations to use in TB control programs. We conducted a randomized clinical trial in South Africa and China that recruited 704 participants with newly diagnosed, drug-sensitive pulmonary tuberculosis and stratified them based on radiographic disease characteristics as assessed by FDG PET/CT scan readers.

Exogenous binding immunoglobulin protein (BiP) enhance immune regulatory phenotype in ex-vivo Mtb infected PBMCs stratified based on QuantiFERON response.

Even though anti-tuberculosis (TB) treatment is readily available, Mycobacterium tuberculosis (Mtb) infection continues to be a global threat with a high death rate recorded from a single infectious agent. This highlights the significance of developing new strategies to curb the growing Mtb infection cases. Host-directed therapies (HDT) offer a promising approach that includes both drug discovery and drug repurposing, aimed at identifying host targets and promoting immune cell populations that can lead to better infection outcomes.

Assessing the propensity of TB clinical isolates to form viable but non-replicating subpopulations.

Current tuberculosis (TB) treatment is typically effective against drug-susceptible Mycobacterium tuberculosis, but can fail due to acquired drug resistance or phenotypic resistance. M. tuberculosis persisters, a subpopulation of viable but non-replicating (VBNR) antibiotic-tolerant bacteria, are thought to contribute to poor TB treatment outcomes.

PneumoniaCheck, a novel aerosol collection device, permits capture of airborne Mycobacterium tuberculosis and characterisation of the cough aeromicrobiome in people with tuberculosis.

Background: Tuberculosis (TB), a major cause of disease and antimicrobial resistance, is spread via aerosols. Aerosols have diagnostic potential and airborne-microbes other than Mycobacterium tuberculosis complex (MTBC) may influence transmission. We evaluated whether PneumoniaCheck (PMC), a commercial aerosol collection device, captures MTBC and the aeromicrobiome of people with TB.
