Filter by:Pulmonary rehabilitation is well established as a treatment in COPD. After exacerbations of COPD, rehabilitation is associated with reduced frequency of exacerbations and improved exercise capacity. No data are available in bronchiectasis. This study will randomly assign patients with bronchiectasis exacerbations to pulmonary rehabilitation or standard care. The hypothesis is that exercise capacity will be improved by pulmonary rehabilitation at 8 weeks.
To test whether POL7080 is effective in patients with exacerbation of non-cystic fibrosis bronchiectasis caused by Pseudomonas aeruginosa infection.
The purpose of this study is to determine whether the medical device "simeox" is safe in the treatment of respiratory diseases, in comparison with traditional physiotherapy.
This study is the first administration of GSK2793660 to humans and will evaluate the safety, tolerability, PK and PD of single oral ascending doses of GSK2793660, and of repeat oral doses of GSK2793660 in healthy subjects. The study will comprise two parts (Part A and Part B). Part A will consist of two cohorts of subjects, each taking part in a three-way cross over study, with ascending doses of GSK2793660 and placebo. Available safety, PK and PD data will be reviewed before each dose escalation. This will be followed by a food-effect arm in the cohort that received what is deemed to be the target clinical dose. Part B is planned to consist of up to two cohorts of subjects, each taking part in one 14 day repeat dose study period. Subjects will be dosed on Day 1 and then on Days 3-15. It is planned that two doses will be evaluated. The dose(s) to be tested will be selected based on safety, PK, and PD from Part A. The study is intended to provide sufficient confidence in the safety profile of the molecule and information on target engagement to allow progression to further studies.
The purpose of this research study is to perfect the technique of EVLP and learn about the safety of transplanting lungs that have been ventilated (attached to a breathing machine or ventilator to deliver oxygen) and perfused with a lung perfusion solution (Steen solution™, made by Vitrolife). This ventilation and perfusion will be done outside the body (ex-vivo) in a modified cardiopulmonary bypass circuit (the kind of device used routinely during most heart surgeries). The purpose of performing ex-vivo lung perfusion and ventilation (EVLP) is to learn how well the lungs work, and whether they are likely safe to transplant.
The research sought to assess the effects of Flutter ® VRP1 in patients with bronchiectasis.
Bronchiectasis is a chronic pulmonary disease characterized by an irreversible dilatation of the bronchi. The current view of the pathogenesis of bronchiectasis considers initial colonization of the lower respiratory tract by different microorganisms as the first step leading to an inflammatory response characterized by neutrophil migration within the airways and secondary secretion of a variety of tissue-damaging oxidants and enzymes such as neutrophil elastase and myeloperoxidase. Persistence of microorganisms in the airways because of impairment in mucus clearance may lead to a vicious circle of events characterized by chronic bacterial colonization, persistent inflammatory reaction, and progressive tissue damage. The exact prevalence of bronchiectasis in COPD patients is not known. It would be important to assess the prevalence, the kind of bronchiectasis and the bacterial colonisation. These are all important features that can be related to the natural history of COPD and to the therapeutic management of patient with COPD and bronchiectasis. Recent data indicate that macrolide long-term treatment and inhaled steroids therapy are both associated with a reduced rate of exacerbation, bronchial colonization and inflammation The present study will address, on a relatively large number of patients, the prevalence of bronchiectasis in COPD subjects using a multislice CT scan technique applied in all the units and centrally analysed by Unit 2 and 4. This analysis will determine the presence and the morphology of bronchiectasis. Bacterial colonization and inflammatory parameters will be evaluated on blood and exhalate bronchial condensate. Concerning bacterial colonization molecular biology techniques (Qualitative PCR and quantitative real time PCR) will be applied. ELISPOT technique for the evaluation of specific immune response will be used.Electron and optical microscopy techniques will be applied on bronchial biopsy samples obtained in a subgroup of patients enrolled. During the second study year, a randomized trial on patients with bronchiectasis will be performed. Patients will be randomized to receive a macrolide or inhaled steroids or standard of care for 6 months with a follow-up of 6 months. All the inflammatory, microbiologic and functional parameters described above will be recorded. A clinical and functional evaluation will be applied looking to number of exacerbations, quality of life, respiratory function parameters.
This study is a randomized, controlled trial examining the effectiveness of the mechanical cough-assist device (in-exsufflator) in promoting the clearance of retained airway secretions in patients with symptomatic bronchiectasis. We hypothesize that this enhanced clearance of airway secretions will lead to a decline in the number of acute exacerbations of bronchiectasis experienced by these patients during the study period, improve health-related quality of life, decrease overall health-care costs and improve pulmonary function.
