Filter by:The purpose of this study was to evaluate the effect of ION-827359 on forced expiratory volume in 1 second (FEV1) in participants with mild to moderate COPD with CB.
This is an observational study examining outcomes and treatment patterns in a community-based cohort of subjects with Chronic obstructive pulmonary disease (COPD) who are based in the Kannapolis, NC area.
The study aims to asses the ability of cell tests based on the analysis of the anti-Aspergillus cell responses and identify Aspergillus bronchitis with patients with cystic fibrosis. In addition, the study will evaluate the contribution of biological classification of aspergillosis according to criteria recently proposed by Baxter et al. compared to the classification used in clinical practice in the hospital of Montpellier.
The purpose of this study is to evaluate the effect of Losartan on cigarette smoke-induced lung injury in smokers and ex-smokers with and without chronic obstructive pulmonary disease (COPD).
To determine the feasibility of delivering different community nutritional interventions to chronic obstructive pulmonary disease (COPD) patients at moderate or severe risk of malnutrition following a hospitalisation for an acute exacerbation of COPD.
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.
N-acetylcysteine (NAC) is described as having mucolytic and antioxidant properties. It is widely prescribed for patients with chronic obstructive lung disease (COPD), particularly for those who have accompanying symptoms of chronic cough and sputum production. Compared to placebo, high-dose NAC will improve Saint George Respiratory Questionnaire scores in patients with COPD and chronic bronchitis.
The purpose of the international plastic bronchitis registry is to understand the natural course and long term health outcomes of subjects diagnosed with plastic bronchitis due to different types of casts. This provides essential data for identifying best practices and treatments. The secondary aim is to understand the structure of casts and mechanism of their formation.
This multicentric, randomized, double-blind and controlled study aims to examine the effect of a fermented dairy product containing the probiotic Lactobacillus casei DN-114 001 (Actimel® = tested product) on the incidence of respiratory and gastro-intestinal common infectious diseases (cumulated number of infections during the intervention period: primary criteria), and on the Quality of Life in adults submitted to multi-stressor situation. Volunteers received either 200g/day of tested product (N=121) or control product (N=118) for 7-weeks.
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.
