The objective of this study is to compare how accurately the Xpert MTB/RIF assay Ct value at diagnosis and the AI-based tuberculosis activity score predict the treatment outcome of rifampin-susceptible pulmonary tuberculosis patients. As a retrospective observational study, data from patients diagnosed with rifampin susceptible pulmonary tuberculosis through the Xpert MTB/RIF assay performed on sputum in 2019 at the participating institutions will be analyzed (up to 900 people).
Some of pulmonary tuberculous patients who completed their medication course experience lung function impairment
Pulmonary tuberculosis (PTB) is the most common cause of lung destruction, contributing to coinfections development, and Aspergillosis spp. is one of the most important. Diagnosis of chronic pulmonary aspergillosis (CPA) in PTB patients is difficult due to similarity of clinical and radiological data, especially in resource-constrained settings. Differentiation of PTB patients with singling out a group with a higher Aspergillus IgG level during the initial examination will help physicians to orient to further examination of CPA. Objectives: to determine the prevalence of aspergillosis in Koch's bacillus-positive and Koch's bacillus-negative PTB patients and antifungal resistance of Aspergillus species isolates in Central Asia countries.
The primary aim of this pragmatic trial is to determine the effectiveness of a Whole Genome Sequencing (WGS) Drug Sensitivity Testing (DST) strategy to guide individualised treatment of rifampicin resistant tuberculosis (RR-TB) patients. The primary objective is to determine the effectiveness of this WGS DST strategy in patients diagnosed with RR-TB. We will additionally perform an exploratory health economics evaluation of both arms, and will determine the feasibility of the WGS DST strategy.
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the causative agent of the Coronavirus disease (COVID-19). Tuberculosis (TB) is the foremost cause of infectious deaths globally. In 2025, an additional 1.4 million TB deaths could occur as direct consequence of the COVID-19 pandemic. It is postulated that individuals with latent or active TB are more susceptible to SARS-CoV-2 disease and that COVID-19 disease rate is high in patients with active TB, although the evidence is still scarce. TB and SARS-CoV-2 are both infectious diseases which primarily attack the alveolar region of the lungs and share common symptoms. SARS-CoV-2 disease can induce innate and adaptive immunity, but uncontrolled inflammatory innate immunity and impaired adaptive immune responses may be associated with severe tissue damage, both locally and systemically. People with coinfection (COVID-19 and TB disease) might potentially have impaired protective immune responses and treatment outcomes, specifically as far as anti-tuberculosis treatment is concerned. However, very little is known about the immunological underpinnings in this interface between TB and COVID-19 on the effect of SARS-CoV-2 disease on disease severity, response to treatment and treatment outcomes in pulmonary tuberculosis. Investigators hypothesize that altered immunity due to prior or present asymptomatic disease with SARS-CoV-2 virus can lead to altered immune responses and systems biology, increased severity and altered treatment outcomes in TB disease. The main objective of the study would be to evaluate the baseline differences in immune cells populations immune cell responses at baseline and at the time of treatment (2nd month) and end of treatment. Further, Investigators would be evaluating the changes in proteomic profiles in a subset of these individuals. In addition, immunological assays examining differences in T cell populations, measuring levels of various cytokines and by immunophenotyping as well as other immune parameters related to innate and adaptive responses will be performed to enhance the understanding of the immunological cross-talk between active TB patients with or without SARS-CoV-2. The secondary objective would be to study the clinical features, disease severity, mycobacterial burden and treatment outcomes in a cohort of SARS-CoV-2 infected (asymptomatic PCR or Antibody+) and non-infected patients with active pulmonary TB.
The current treatment regimen for MDR-TB has poor outcomes and costs of treating MDR-TB are greater than treating drug susceptible TB, both in terms of health service and patient-incurred costs. Urgent action is needed to Identify short, effective and tolerable treatments for people with MDR-TB. The PRACTECAL economic evaluation sub-study (PRACTECAL-EE) will take place alongside the TB PRACTECAL trial, aiming to assess the costs to patients and providers of such regimens and to estimate the cost-effectiveness and poverty impact of an introduction of new MDR-TB regimens in the three countries participating in the main study.
Bronchiectasis was described in the early 19th century by Laennec. Bronchiectasis is a chronic condition characterized by permanent and irreversible dilatation of the bronchial airways and impairment of mucociliary transport mechanism due to repeated infection and inflammation leading to colonization of organism and pooling of the mucus in the bronchial tree
This is a prospective, open label, two-centre, randomized, controlled, two-stage, phase Ib/IIa study to evaluate the safety, tolerability, PK, drug-drug interaction and bactericidal activity of BTZ-043 administered orally once daily over 14 days to participants with newly diagnosed, uncomplicated, smear-positive, drug-susceptible pulmonary tuberculosis. The primary objective is to assess the safety and tolerability of BTZ-043 given over 14 days by evaluation of adverse events during treatment and follow-up period in patients with newly diagnosed, uncomplicated, smear-positive, drug-susceptible pulmonary tuberculosis.
endTB-Q Clinical Trial is a Phase III, randomized, controlled, open-label, non-inferiority, multi-country trial evaluating the efficacy and safety of two new, all-oral, shortened regimens for multidrug-resistant tuberculosis (MDR-TB) with fluoroquinolone resistance.
