NCT03443414
The study investigates the effect of 4 weeks of twice daily treatment of four different doses of RPL554 (a phosphodiesterase \[PDE\]3/4 inhibitor) or placebo in patients with moderate to severe chronic obstructive pulmonary disease (COPD). Patients will be equally allocated to one of the five treatment options.
NCT03271905
Aerosol therapy is widely used in intensive care in critically ill patients that use mechanical ventilation (MV). However, there is a lack of standardization about aerosol performance in this group of patients. Thus, this study aims to evaluate the effect of nebulization performed in different ventilatory modes on lung function and regional pulmonary distribution of critical patients with chronic obstructive pulmonary disease. It is a clinical trial, crossover, randomized, controlled and blind. Three interventions with bronchodilators will be performed: in the Pressure Controlled Ventilation mode (PCV) with positive end expiratory pressure (PEEP) = 85% of autoPEEP, in the PCV mode with PEEP = 15 cmH2Oand in the Pressure Support Mode (PSV). Pulmonary function data will be evaluated through Electrical Impedance Tomography to evaluate the efficacy of the bronchodilator in different ventilatory modes.

NCT03950531
Chronic obstructive pulmonary disease (COPD) is a chronic inflammatory disease of the airways and lungs that develops against harmful particles or gases with exacerbations. Coexistence of bronchiectasis with COPD may lead to worsening of the functional parameters as well as alteration of the microbiological pattern in exacerbations and may negatively affect the exacerbation result parameters.
NCT02978703
Observational study for the evaluation of clinical effectiveness in daily clinical practice of inhaled combination of propionic Fluticasone and Salmeterol in doses (500+50)mcg - Rolenium- administered with Elpenhaler device in approximately 2000 COPD (Chronic Obstructive Pulmonary Disease) patients with a FEV1 \<50% predicted normal (pre-bronchodilator), a history of repeated exacerbations and who have significant symptoms despite regular bronchodilator therapy in Greece.
NCT03349437
Dyspnea is the most common symptom limiting the ability of COPD patients to perform activities of daily living. Although there has been research involving the benefit of providing Non Invasive Ventilation (NIV) during exercise to increase tolerance overall, there is little research specifically looking at shortening dyspnea recovery times associated with exercise. We hypothesize that providing intermittent non-invasive positive pressure therapy (a form of NIV or PAP) with a handheld device to COPD patients immediately after exertion can relieve their dyspnea, and consequently allow them to be more active. In this study, we are comparing the distance walked as measured by a modified 6-Minute Walk Test (6MWT) of 20 COPD patients using VitaBreath (NIV) device versus Pursed Lip Breathing.
NCT03942302
Validate a simple clinical tool to evaluate physical activity (the question "How many minutes does it walk per day?" Or equivalent), compared to the rest of the collected physical activity data (PROactive questionnaire and objective physical activity data by means of an accelerometer record) in patients with COPD.
NCT01656421
Patients with chronic obstructive pulmonary disease (COPD) have an increased risk of cardiovascular disease,osteoporosis, muscle wasting and diabetes mellitus. Cardiovascular disease is a major cause of death in such patients and it may be related to excess stiffening of the walls of major arteries, such as the aorta, and it has been suggested to represent premature aging. However, there is little known of the development of these problems, which were previously considered to be due to smoking and which is now known not to be the only factor. The investigators will study a large group of patients with mild to very severe airflow obstruction based on the NICE 2010 classification of severity and a matched comparator group free of COPD. This study involves three assessments of the development of the complications of COPD over a five year period. The key measure will be the rate of change in the aortic wall stiffness, an accepted indicator of the risk of heart disease. Changes in wall stiffness will be related to the severity of lung disease; other known cardiovascular risk factors, such as high blood pressure, increased blood cholesterol and to cardiovascular events including heart attacks and death; and to the presence of other complications, such as osteoporosis, muscle wasting and diabetes mellitus. These measures will be analysed in the context of changes in bodywide inflammation and metabolic function and the changes in the rate of ageing. This increased knowledge of interacting factors in the complications of COPD is likely to lead to studies of treatments to avoid their development.
NCT01380639
The aim of this study is to investigate the exercise capacity in COPD-patients performing a vibration training additional to a standard three-week rehabilitation program in comparison to patients performing merely a rehabilitation program.
NCT03928535
To test if high-flow conditioned oxygen therapy is noninferior to NIV for preventing postextubation respiratory failure and reintubation in patients with hypercapnic COPD, investigators plan to conduct the participants level, 1:1 randomized trial at the respiratory ICU. Participants were randomized to undergo either high-flow conditioned oxygen therapy or noninvasive mechanical ventilation after extubation. Primary outcomes were reintubation and postextubation respiratory failure within 72 hours. Secondary outcomes included length of RICU stay after extubation and mortality; partial pressure of arterial carbon dioxide.

Studying the microbiome of the lung in patients treated with endobronchial lung volume reduction coils for emphysema
NCT03923803
Chronic obstructive pulmonary disease is a serious disease . Exacerbations of Chronic obstructive pulmonary disease is an acute worsening condition of Chronic obstructive pulmonary disease, which always accompanied by clinical symptoms such as, shortness of breath and increased production of sputum. Respiratory infection (bacteria or viruses or mixed) is thought to be the main cause in most exacerbations.
NCT03921983
Peripheral muscle oxidative function is altered in COPD(chronic obstrutive pulmonary disease) patients. Multiple factors could contribute to this dysfunction including chronic hypoxia and deconditioning (sedentarity). The evaluation of mitochondrial function is based on invasive method (muscle biopsy and in vitro respirometry) or magnetic resonance spectroscopy limited to small muscle groups. Recently, a non invasive method has been described using Near InfraRed Spectroscopy (NIRS). During arterial occlusion, muscle deoxygenation is only dependent of local oxygen consumption. The time constant recovery (k) of the deoxygenation during repeated ischemia periods has been shown to be correlated to measurements of maximal mitochondrial capacity. k is lower in COPD patients compared to smokers without bronchial obstruction. However, the influence of arterial hypoxia has never been studied precisely, no more than the confounding effect of deconditioning on k. So , the aim is to compare k in COPD patients with chronic hypoxemia (treated with long term oxygenotherapy, LTOT+ group) and patients without hypoxia, matched for their physical activity (LTOT- group). The hypothe is that k will be lower in LTOT+ group compared to LTOT- group and that short term O2 supplementation will improve it, which would suggest a muscle hypoxia. By contrast, O2 should not influence k in LOT- group, in whom it is mainly determined by muscle conditioning.
NCT03197909
Chronic Obstructive Pulmonary Patients is a defined by persistent airflow limitation that is usually progressive and associated with an enhanced chronic inflammatory response in the airways and the lung to noxious particles or gases. It is associated with an atrophy of the skeletal muscle that impairs the patient's prognosis. The biological mechanisms of this muscle atrophy have not been elucidated, and the "spill-over theory" has recently emerged. Indeed, in COPD patients, the pulmonary inflammation is associated with a systemic low-grade inflammation, and the increased pro-inflamatory molelcules in the blood - which constitute the cellular micro-environement of the muscle fibre - could activate the mechanisms of the cell atrophy.
NCT03179826
Chronic obstructive pulmonary disease (COPD) and asthma are frequent and disabling pathologies. The general practitioner is often at the front line vis-a-vis screening, diagnosis and treatment of these pathologies. There are currently many treatments available, in particular inhaled corticosteroids, and although the recommendations for management appear to be well codified in theory, the adaptation of drug therapy remains complex in general practice. The prescription of inhaled corticosteroids, often initiated during a general medicine consultation, is not simple. The aim of this study is to analyze the relevance of the prescription of inhaled corticosteroids in primary care and to identify the criteria necessary for the prescription of inhaled corticosteroids available in general practice. The main objective of our study is to evaluate the rate of consultations where all the elements required for guiding the prescription of an inhaled corticoid are available. The secondary objectives are: * Identify other factors associated with decision-making * Identify the causes of inhaled corticosteroid stopping (de-prescription)
NCT03910985

NCT00921921
Chronic obstructive pulmonary disease or 'COPD' is a chronic disease, which means that it cannot be cured, but that inhalers and tablets can be used to control the symptoms. In COPD, the airways become inflamed which can cause coughing and make the airways tighten. This 'inflammation' is the root of the problem in COPD. The airways of the lung start in the windpipe and branch like the branches of a tree, getting smaller and smaller. In COPD the inflammation is deep in the lungs, out to the very small airways. Different inhalers make the medicines into different sized particles. Most steroid inhalers used for COPD make the medicine into particles which are too big to get into the very small airways ('coarse particles'). Other inhalers make a mist, with much smaller particles ('fine particles'). These are as small as the smallest airways in the lungs. Doctors have recently found a way to measure the inflammation in the small airways that are affected in COPD. The investigators want to find out if taking one of these 'fine-particle' steroid inhalers can treat that inflammation.
NCT01630200
Chronic obstructive pulmonary disease is associated with a low grade systemic inflammatory process. Systemic inflammation is hypothesized to maintain cardiovascular morbidity and mortality in COPD. Early changes of vascular integrity can be detected via markers of subclinical atherosclerosis. Selective Inhibition of phosphodiesterase subtype 4 describes a promising therapeutic option in COPD with beneficial impact on lung function and exacerbation rate. Moreover, an anti-inflammatory effect of phosphodiesterase-4 inhibition was confirmed by recent data. The aim of this study is to assess the effects of the phosphodiesterase-4 inhibitor Roflumilast on firstly surrogates of subclinical atherosclerosis and secondly markers of systemic inflammation in the peripheral circulation of patients with stable chronic obstructive pulmonary disease.
NCT02640430
BACKGROUND: Studies have shown that COPD patients with bronchial hypersecretion have increased risk of acute exacerbations. FREE ASPIRE is an electro-medical device which removes bronchopulmonary secretions noninvasively, without using a suction catheter and without generating airway pressure. AIM: To compare FREE ASPIRE activity with the traditional treatment using PEP-bottle in the clearance of bronchial secretions in COPD patients METHODS: Forty severe and very severe COPD patients with mucus and reduced cough will be evaluated. Group comparison will be made between Intervention group using VAKÜM system (Free Aspire®), and Control group using traditional treatment with PEP-bottle over 10 daily sessions (20 minutes twice a day). Primary outcomes are changes in arterial blood gases exchanges, in perceived dyspnea and in symptom of bronchial encumbrance. EXPECTED RESULTS: A higher significant reduction of the perceived dyspnea and of perceived bronchial encumbrance is supposed in the Intervention group. Additional benefits among the secondary outcomes are also hypothesized in the same group.
NCT03564028
Chronic obstructive pulmonary disease (COPD) is characterised by non-reversible bronchial obstruction associated with systemic disorders and comorbid factors. Dynamic hyperinflation during an exercise increase dyspnea and can reduce exercise capacity. Stair climbing is associated with prolonged dynamic hyperinflation and severe dyspnea in COPD patients. The aim of this study is to carry out the effect of an energy conservation technique on dyspnea to facilitate stair climbing.
