Filter by:This is a phase IV study of indacaterol 75 μg single-dose compared to placebo in moderate-severe COPD patients with breathing symptoms to assess time to patient's perception of onset of effect.
The aim of this study is to reduce the number of subsequent hospital admissions and/or emergency department (ED) visits for hospitalized patients with chronic obstructive pulmonary disease (COPD) by utilizing a respiratory care practitioner-led disease management (RCP-DM) program compared to standard discharge instructions and planning.
The main purpose of this study is to determine the effect of Losmapimod on blood vessels in patients with Chronic Obstructive Pulmonary Disease (COPD). Although COPD is a lung disease, it is also associated with an increased risk of cardiovascular disease (e.g. heart attacks and stroke). The investigators believe that this is a result of inflammation within the body, which damages the lining (endothelium) and walls of blood vessels. These changes can promote the development of fatty deposits within the walls of arteries (atherosclerosis) which can rupture and block arteries causing damage.
This study was designed to evaluate the effectiveness of 12 weeks' home exercise training using the Nintendo ® Wii Fit system in patients with COPD. Following an initial pilot study at one institution to determine the physiological responses to exercise training using the home based interactive computer system, a longitudinal study was performed to evaluate outcomes across several areas. Outcomes were measured at baseline, after 6 weeks of standard care, and after 6 and 12 weeks of home exercise training. Three hospital based pulmonary rehabilitation centers in Connecticut participated in the longitudinal study.
Sustained improvement after pulmonary rehabilitation in activity levels as measured by an activity armband. Pulmonary rehabilitation is utilized to improve exercise capacity, quality of life and prognosis for patients who suffer from chronic obstructive pulmonary disease. There is also strong evidence that supports the use of pulmonary rehabilitation to decrease hospital admissions thereby reducing cost of care. Recent studies suggest that the significant benefits achieved through rehabilitation fade with time and that in order to improve activities of daily living; for example, average daily number of steps, programmes of longer duration are required. The primary aim of this study is to identify objective sustained improved in activity levels using the SenseWear activity armband after a short-term pulmonary rehabilitation programme. Secondary aims are to determine antibiotic and steroid use pre and post rehabilitation.
The study assessed the safety and efficacy of the fixed combination product QVA149 versus the component products QAB149 and NVA237, administered concurrently, in patients that have moderate to severe chronic obstructive pulmonary disease (COPD).
Patients with chronic obstructive pulmonary disease (COPD) present slowed pulmonary oxygen uptake (VO2) and heart rate (HR) kinetics compared with age-matched controls. Patients with COPD present significant loss of body mass, decreased strength and endurance of respiratory muscles and lower limbs, leading reduced exercise capacity. This reduced exercise capacity can be marked by slowed kinetics of VO2 and HR at the onset of heavy-intensity exercise. Additionally, derangements in the diffusive and convective transport of oxygen to skeletal muscle mitocondria, and intramyocyte metabolic machinery, higher ventilation and disturbances in mechanics of breathing, hypoxemia, pulmonary hemodynamics, autonomic balance, and peripheral vasodilation, and accumulation of by-products that might be related to increased muscle fatigability could slow the response of systemic (central) and peripheral (microvascular) oxygen delivery to a point where the kinetics of VO2 might become limited by O2 availability and HR. Thus, the physical training programs of the lower limbs, in addition to presenting scientific evidence "A", are important components, resulting in the reversal of the manifestations of COPD, resulting in improvement in exercise capacity, well significantly speeded VO2 and HR kinetics in patients with COPD. However, it should be taken into account the choice of an appropriate program limitations and severity of disease. Assuming that COPD patients present slower VO2 and HR kinetics, the investigators hypothesized that the heavy-intense interval physical training in equipament elliptical would promote a greater increase in the functionality (functional performance) and speeded kinetics in the cycle ergometer and elliptical equipment constant-load intense exercises tests of COPD patients. In this context, the present study intends to evaluate and compare the effects of resistive plus aerobic physical training and interval physical training on oxygen consumption (VO2) and heart rate (HR) kinetics responses at the onset in cycle ergometer and elliptical equipment constant-load intense exercises tests in patients with COPD.
TOPDOCS is a prospective cohort study including COPD patients from currently six study centers in Switzerland. Patients with COPD GOLD stages I-IV will be enrolled and followed-up annually for at least 3 years. Yearly assessments will include a detailed patient history, quality of life and activity questionnaires, history of exacerbations, lung function, measurements of exercise capacity, measurements of vascular function, exhaled breath analysis and blood sampling. The overall objective of the project is to establish a meticulously characterized cohort of COPD patients living in Switzerland in order to allow high quality research on the pathogenesis, treatment and complications of COPD. The specific aim of the project is to determine clinically relevant COPD phenotypes and biological factors influencing vascular function in COPD patients.
Chronic Obstructive Pulmonary disease (COPD) patients with chronic hypercapnic respiratory failure are more likely to develop exacerbations. Non-invasive ventilation has been proposed to treat acute respiratory failure but little information is available about the benefits of home non-invasive ventilation in COPD patients with chronic hypercapnic respiratory failure surviving an acute hypercapnic respiratory failure. The purpose of this study is to determine whether home non-invasive ventilation can reduce recurrent acute hypercapnic respiratory failure in COPD patients who survived an episode of acute hypoxemic respiratory failure (AHRF) treated by Non-invasive ventilation (NIV).
The investigators design a pilot randomised, single-centred, controlled trial to compare different withdrawal methods of Non-invasive ventilation. Our study aims at comparing stepwise withdrawal of Non-invasive ventilation versus immediate withdrawal of Non-invasive ventilation. The primary endpoint is to compare the rate of success between two withdrawal methods. The investigators define success as no recurrence of acute hypercapnic respiratory failure or restitution of Non-invasive ventilation within 48 hours after NIV is stopped. The secondary endpoints include time to recurrence of acute hypercapnic respiratory failure measured from the time of randomisation, the total days of Non-invasive ventilation use and the days of hospitalisation. Results from this trial will inform design of future randomised trial in this area.
