Filter by:The principal research objectives are to demonstrate cardioselective beta-blockade using bisoprolol is not inferior to placebo with regard to pulmonary function and improves quality of life in patients with heart failure and coexistent moderate or severe chronic obstructive pulmonary disease with or without significant reversibility. Patients will be followed up for 4 months during which bisoprolol will be up-titrated to the maximum clinically tolerated dose. Health status will be assessed using a generic and two disease specific questionnaires, and pulmonary function by spirometry, body box plethysmography, and cardiopulmonary exercise testing.
The purpose of this study is to determine whether lozenges containing interferon-alpha can reduce the frequency and severity of coughing in patients with chronic obstructive pulmonary disease (COPD) and idiopathic pulmonary fibrosis (IPF).
Most people undergoing lung transplantation have chronic obstructive pulmonary disease (COPD), a disease in which the lung airways are partly damaged and obstructed, making it difficult to breathe. This study will enroll people with COPD who are undergoing a lung transplant to examine how their quality of life changes after the transplant procedure.
The primary objectives of this study are to assess bronchodilator efficacy as determined by forced expiratory volume in one second (FEV1), the effect on dyspnoea as determined by the Baseline Dyspnoea Index/Transition Dyspnoea Index (BDI/TDI), the effect on health status as determined by the St George Respiratory Questionnaire (SGRQ) and the effect on chronic obstructive pulmonary disease (COPD) exacerbations.
Examine the effects of TI in combination with an anti-diabetic regimen including inhaled insulin versus anti-diabetic treatment without inhaled insulin on lung function & pulmonary safety
Twenty per cent of the intensive care patients mechanically ventilated suffer from chronic obstructive pulmonary disease (COPD). These patients stay longer in Intensive Care which is more costly and they are more prone to nosocomial infection.In addition, they are longer bedridden and they develop muscular weakness.Prolonged inactivity results in respiratory and skeletal muscle weakness which curtails simple daily activity.The principal purpose of this study is to compare two types of muscular rehabilitation (electrical stimulation of the thigh and/or cycloergometer training) to classic passive mobilization of the leg.The second purpose is to analyse the effects of each type of rehabilitation on muscular fiber (structural and functional analysis) by muscular biopsies.Two hundred forty COPD patients admitted in the intensive care unit for acute respiratory failure will be randomized in 4: 1 fashion to receive passive mobilization of the legs(group 1, n=60), electrical stimulation of the thigh (group 2, n=60), cycloergometer training (group 3, n=60) or electrical stimulation of the thigh and cycloergometer training(group 4, n=60).The rehabilitation program will last 4 weeks with 5 sessions per week.In each group of patients, muscular biopsies will be done under local anaesthesia at the beginning and end of the rehabilitation programme and when they are discharged from the service.
The purpose of this study to determine the safety and effectiveness of a mechanical device to remove carbon dioxide from the blood of patients with chronic obstructive pulmonary disease (COPD)when they are hospitalized in the intensive care unit for exacerbation of their condition.
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.
The purpose of this study is to determine which COPD patients have GERD and if COPD patients with GERD treated with high dose lansoprazole for 1 year decreases the frequency of COPD exacerbations compared to the previous year without treatment.
Chronic obstructive pulmonary disease (COPD) is a long-term lung disease that is caused by cigarette smoking or by breathing in other lung irritants, including pollution, dust, or chemicals. The purpose of this study is to evaluate the effectiveness of zileuton, a medication that is used to control asthma symptoms, at reducing the length of a hospital stay for adults who are hospitalized for a COPD exacerbation, or worsening of COPD symptoms.
