Filter by:This study is open to adults with bronchiectasis. People can join the study if they produce sputum and have a history of flare-ups (also called exacerbations). The purpose of this study is to find out whether a medicine called BI 1291583 helps people with bronchiectasis. Participants are put into 4 groups randomly, which means by chance. Participants in groups 1, 2, and 3 get different doses of BI 1291583. Participants in group 4 get placebo. Placebo tablets look like BI 1291583 tablets, but do not contain any medicine. Participants take the tablets once a day. Participants are in the study for between 6 months and 1 year. During this time, they visit the study site about 10 times and get about 5 phone calls from the site staff. The doctors document when participants experience flare-ups during the study. The time to the first flare-ups is compared between the treatment groups. Doctors also regularly check participants' health and take note of any unwanted effects.
Asthma is a chronic respiratory disorder characterized by bronchial inflammation and reversible bronchial obstruction. Severe asthma is an extremely heterogeneous disease, often associated with several comorbidities and risk factors. Severe uncontrolled asthma associated with bronchiectasis is an emerging phenotype. Several studies have attempted to establish an association between asthma and bronchiectasis. Mepolizumab, an Interleukin-5 (IL-5) antagonist, reduces exacerbations, eosinophils, and improves pulmonary function and asthma control. IL-5 is pivotal to eosinophils maturation and release from bone marrow, their subsequent accumulation, activation and persistence in the tissues. IL-5 therefore represents an attractive target to prevent or blunt eosinophils-mediated inflammation. The investigators hypothesize that eosinophils, stimulated by IL-5, play a crucial role in severe asthma and BE pathogenesis.
The bronchodilators (BD) have been widely used in bronchiectasis (BCE) therapeutic and have been shown to be effective in improving exercise capacity in patients with chronic obstructive pulmonary disease and asthma. However the BD effect on the exercise capacity of patients with BCE is poorly known. Besides, the respiratory mechanics pattern of the patients with BCE is not known nor its association with their physical activity level (PAL). Therefore, the hypothesis of this study is that BD are effective in improving exercise capacity of patients with BCE. The authors also propose to characterize the respiratory mechanics of the patients with BCE and to evaluate their PAL and its association with quality of life, as secondary aims.
To determine the effect of pulmonary rehabilitation on pulmonary function in non-chronic obstructive pulmonary disease patients.To determine the effect of pulmonary rehabilitation on health related quality of life in non-chronic obstructive pulmonary disease patients.Limited researches are available in non chronic obstructive pulmonary disease patients.
Bronchiectasis is a common disease worldwide with a high burden on healthcare resources. In Hong Kong (HK), local microbiological and clinical data regarding acute exacerbation of bronchiectasis (AEB) is lacking, in particular the frequency of pseudomonas aeruginosa (PA) in AEB is yet to be elucidated. A better understanding of the microbiology of AEB will provide evidence for judicious use of appropriate antibiotics in patients hospitalized for AEB to facilitate treatment and discharge. This study aims to 1. elucidate the microbiology of AEB using both traditional culture and newer molecular multiplex methods, 2. identify factors associated with PA infection, and 3. describe the management and treatment outcome of AEB in HK
Bronchiectasis is a chronic lung disease characterized by permanent dilatation and destruction, resulting from the destruction of elastic tissue and muscular components in the bronchial walls, due to infection or inflammation. The exercise tolerance, physical activity level, respiratory and peripheral muscle strength of patients with bronchiectasis are lower than those of healthy individuals. The decrease in exercise tolerance occurs while performing upper extremity activities as well as lower extremity tasks. Many studies have reported that upper extremity exercise capacity is reduced in chronic obstructive pulmonary disease (COPD), a disease similar to bronchiectasis, and that patients often experience significant dyspnea and fatigue during upper extremity tasks that are important for daily life. The mechanisms causing this situation may be neuromechanical dysfunction of the respiratory muscles (diaphragm and accessory respiratory muscles) (thoracoabdominal asynchrony) and changes in lung volume in activities involving the upper extremities. The disturbances in ventilatory mechanics in patients with COPD cause upper extremity exercise to be terminated at low workloads compared to healthy individuals. Upper extremity exercise has been defined as part of pulmonary rehabilitation. The determination of upper extremity exercise capacity may play a predictive role in maintaining and improving upper extremity and daily life activity level in patients with chronic lung disease. Six-minute Pegboard and Ring test (6PBRT) is used to evaluate extremity exercise capacity and upper extremity function and endurance. The 6PBRT score and upper extremity daily living activities show a clear relationship in patients with COPD, and it can be used to determine and improve the performance of daily living activities in pulmonary rehabilitation programs. Glittre Activities of Daily Living (Glittre ADL test) covers activities that are necessary for daily living and commonly used activities. The Glittre ADL test produces similar cardiorespiratory responses when compared with the six-minute walk test. In this study, unsupported upper extremity exercise capacity and upper extremity function/endurance and the performance of daily living activities will be compared in participants with bronchiectasis and compared with healthy individuals.
Bronchiectasis is characterized pathologically by permanent bronchial dilatation and airway inflammation. The pathogenesis of the disease and the inflammatory, infective and molecular drivers of disease progression are not fully understood. The concept of "treatable traits" was proposed as biomarker-directed approach, based on the recognition of clinical phenotype and endotypes, help to personalized treatment options. Airway microbiota, including bacteria, NTM and fungus, have important but different inflammatory process in bronchiectasis. Our study will provide a new concept that airway microbiota might involve in the airway and systemic inflammation, mucus hypersecretion, as well as the airway damage, remodeling, and frequent exacerbations in bronchiectasis, thus leading to the deterioration of disease severity. Bronchiectasis remains a major cause of respiratory morbidity and treatment is generally only partly successful. Our study will give more clues about the mechanisms on the inflammatory pathway and the probably different response among patients with different isolated microbiota from airways.
Oscillatory positive expiratory pressure (OPEP) devices such as Flutter®, Aerobika® or Shaker ® are commonly prescribed in the clinical practice for airway clearance in children with chronic lung diseases including bronchiectasis, cystic fibrosis, and primary ciliary dyskinesia. Health insurance companies may cover these devices in some countries; but this is not a common practice around the world. Therefore, many families have to purchase these devices themselves. Unfortunately, these devices are rather expensive especially in the developing countries and consequently, families become financially burdened. Aim of this study is to investigate whether the addition of OPEP devices to a comprehensive chest physiotherapy program provide additional benefits on pulmonary function and exercise capacity in children with bronchiectasis. Results of this study may help better interpreting the cost-effectiveness of these devices.
This is a multicentre, randomised, double-blind, parallel-group, placebo-controlled, phase III study originally designed to test the hypothesis that benralizumab will reduce exacerbation rates compared with placebo on top of standard-of-care therapy in adult patients with non-cystic fibrosis bronchiectasis with eosinophilic inflammation (NCFB+EI). All patients who complete the double-blind treatment period (28 to 52 weeks depending on the timing of patient randomization and when the revised CSP version 3.0 becomes effective) on investigational product (IP) may be eligible to continue into an open-label extension (OLE) period during which all patients will receive benralizumab. The revised OLE period is intended to allow patients approximately 32 weeks of treatment with open label benralizumab (24 weeks followed by a FU visit 8 weeks after the last dose of IP for a total of approximately 32 weeks).
Bronchiectasis is a chronic respiratory disease characterized by permanent bronchiectasis.The incidence and prevalence of bronchiectasis have assumed continuously grows in global. Different from overseas, bronchiectasis is common disease in China. This study will collect data from the real-world bronchiectasis database and follow up for one year, describe the bronchiectasis exacerbation rate and proportions for frequent exacerbation, clinical features and prognosis of bronchiectasis exacerbation, the treatment pattern (when clinically stable) during follow-up period; and describe characteristics of bronchiectasis at baseline. This study will also explore potential baseline risk factors for bronchiectasis exacerbation during follow-up period.
