Filter by:Study participants with non-cystic fibrosis bronchiectasis will be given Trikafta for four weeks. The researchers will monitor clinical endpoints, quality of life, and weight. Additionally, cutaneous punch biopsy material will be collected from each participant to test cellular response to Trikafta.
Patients with Bronchiectasis experience exacerbations with hypercapnic respiratory failure associated with an increased respiratory workload that may require intensive care unit (ICU) admission due to the inability of the respiratory muscles to compensate for increased demand. These exacerbations are frequently treated with noninvasive ventilation (NIV).
Bronchiectasis is a chronic inflammatory respiratory disease defined as the irreversible dilatation of one or more bronchi and is associated with chronic and frequently purulent expectoration, multiple exacerbations and progressive dyspnea. Bronchiectasis has a large heterogeneity. Different patients with bronchiectasis may have different etiology, clinical manifestations, and imaging features. Previous studies showed that there are significant relationship between the airway microbiome and the severity of the disease. For example, patient with airway Pseudomonas aeruginosa colonization has heavier symptoms, heavier severity, poorer quality of life, more acute exacerbations, and worse prognosis. A large number of studies have reported that long-term treatment of low-dose macrolides such as azithromycin or clarithromycin has anti-inflammatory and immunomodulatory effects, which can improve the clinical symptoms and disease progression of various chronic airway diseases, such as diffuse panbronchiolitis, chronic obstructive pulmonary disease, bronchiectasis. Both the 2017 European Respiratory Society guidelines and the 2019 British Thoracic Society Guideline recommend macrolide drugs for the treatment of chronic Pseudomonas aeruginosa colonization bronchiectasis or frequent acute exacerbations bronchiectasis, but the specific mechanism is unknown.This study is based on omics methods (Microbiology and Metabolomics) to deeply explore the composition of airway and gut microbiota in patients with bronchiectasis, the factors affecting the colonization of Pseudomonas aeruginosa and the mechanism of macrolides in the treatment of bronchiectasis. This study collected clinical data of bronchiectasis (including demographic information, clinical characteristics, lung function, and lung imaging), spontaneous sputum, stool, and peripheral blood, and followed up these patients for 12 months. Microbiology，metabolomics and cytokine in sputum and stool are tested, and cytokines, inflammatory mediators and metabolites in peripheral blood are tested. Through the above methods,investigators further understand the mechanism affecting progression of bronchiectasis and some factors that lead to the colonization of Pseudomonas aeruginosa, as well as mechanisms of macrolides in the treatment of bronchiectasis.
A phase 2, multi-center, double-blind, randomized, placebo-controlled study to evaluate the safety, phage kinetics, and efficacy of inhaled AP-PA02 administered in subjects with non-cystic fibrosis bronchiectasis and chronic pulmonary Pseudomonas aeruginosa infection.
The study carries out Sweet Tests and CFTR-mutation screening to explore the prevalence, clinical characteristics, and prognosis of cystic fibrosis, as well as the CFTR-mutation spectrum in Chinese adults with bronchiectasis. The study is multi-centered, prospective, non-interventional, and observational.
This is a phase II, randomised, double-blind, placebo-controlled, multicenter study to assess the efficacy and safety of HSK31858 in non-cystic fibrosis bronchiectasis (NCFBE) participants.
Double-blind, randomized, cross-over trial involving 20 participants with bronchiectasis. This trial will make an important contribution to therapeutic development in bronchiectasis by determining whether alpha-1 antitrypsin (AAT) therapy results in reduced airway inflammation and improves neutrophil function. Patients will be randomly assigned to receive Prolastin-C 120mg/kg (n=10 patients) by weekly intravenous infusions, Prolastin-C 180mg/kg (n=10 patients) by weekly intravenous infusions or placebo (0.9% saline) for a period of 4 weeks, followed by a 3-5 week washout period and a further 4 weeks during which patients will cross-over to receive the alternative therapy.
The purpose of this study is to evaluate the feasibility and the mid-term effects of a pulmonary rehabilitation intervention, delivered by digital App, on quality of life of patients affected by respiratory diseases. The App will include a monitored exercise training program based on most recent cardiopulmonary rehabilitation guidelines, including alerts, reminders and educational contents as well as chat and online visits with healthcare professionals to improve patient engagement.
The main purpose of this study is to investigate whether long-term oral administration of Staphylococcus albicans tablets can significantly reduce the number of acute exacerbations in patients with bronchiectasis. Secondary objective is to explore whether long-term oral administration of Staphylococcus albicans tablets can reduce the risk of hospitalization in patients with bronchiectasis and whether it can improve the quality of life of patients. Other purpose is to explore the regulatory effect of long-term oral administration of Staphylococcus albicans tablets on the immune function of patients with bronchiectasis.
The aim of this study is to determine whether an intervention with frequent thermotherapy will be able to reduce the amount of colonizing bacteria in the bronchoalveolar lavage sample and eradicate the colonizing bacteria.
