Recently, direct evidences point to the contributing role of peripheral muscle fatigue in exercise tolerance among patients with COPD. However, the physiological mechanisms by which peripheral muscle fatigue impairs exercise tolerance are still unknown, as factors regulating peripheral muscle fatigue in COPD may be complex. One possible link between limb muscle fatigue and exercise intolerance could be enhanced afferent signals from the active limb muscles to the central command, thereby limiting central motor output and eventually leading to exercise termination. A direct method to investigate the regulation of peripheral muscle fatigue during exercise in patients with COPD is the blockade of peripheral neural afferents via lumbar anesthesia. Consequently, investigating the interplay between the peripheral muscular component and the central motor command during self-paced exercise could shed light on the regulation of peripheral muscle fatigue in COPD and its implication in exercise intolerance.
GSK573719 is a high-affinity specific muscarinic receptor (mAChR) antagonist which is being developed for the treatment of chronic obstructive pulmonary disease (COPD). The long duration of action of GSK573719, when administered via inhalation to humans supports the potential for use as a long acting bronchodilator.This is a randomized, double-blind, placebo-controlled, 5 period cross-over study in healthy male and female volunteers. The study will measure lung function after single inhaled doses from two configurations of the Novel Dry Powder Inhaler. Key assessments will include clinical relevant PD parameters: sGaw, FEV1
This is a randomized, placebo controlled, four period incomplete block,crossover thorough QT study to estimate the effect of repeat dose GSK573719/GW642444M (Vilanterol) combination and GSK573719 monotherapy on the QTc interval in healthy male and female subjects compared with placebo. At least 100 subjects will receive, four of five possible, 10-day repeat dose treatments. Treatments are placebo with a moxifloxacin placebo on day 10, placebo with moxifloxacin (400mg) on day 10, GSK573719/Vilanterol combination (125/25μg) with moxifloxacin placebo on day 10, GSK573719/Vilanterol combinatio (500/100μg) with moxifloxacin placebo on day 10, or GSK573719 (500μg) with a moxifloxacin placebo on day 10. All treatments are double blind except for moxifloxacin (400mg) and moxifloxacin placebo controls, given as a single-blind single dose on Day 10 of the appropriate treatment period. Primary endpoints are individual time-matched changes from baseline QTcF for GSK573719/Vilanterol combination (125/25μg) and GSK573719 (500μg), 0-24 hours after dosing on Day 10. Secondary endpoints will include individual time-matched changes from baseline in QTcF for GSK573719/Vilanterol combination (500/100μg) and moxifloxacin (400mcg) 0-24 hours after dosing on Day 10. Also changes from baseline in QTci, QTcB, QT, QRS, RR, PR and ventricular rate at each time point after 10 days dosing of each GSK573719 and GSK573719/Vilanterol treatment and single dose moxifloxacin (400mg). Maximal change from baseline 0-24hours after dosing on day 10 will be derived for QTcF, QTci and QTcB for each treatment. Plasma concentrations on Day 10 (0-24 hours) and pharmacokinetic parameters of GSK573719 and Vilanterol will also be derived. Key assessments: 12- lead electrocardiogram (ECG), pharmacokinetics. Safety will be assessed by blood pressure, heart rate, clinical laboratory safety tests and collection of adverse events (AEs).
This study will try to elucidate wheter the impact of a psychiatric intervention in patients hospitalized because an acute exacerbation of COPD and anxiety/depression and reconsulting at 1 and 6 month after discharge.
In the investigators' knowledge there are no data about the impact of non invasive mechanical ventilation on the breathing-swallowing interaction. Our main objective is to evaluate breathing-swallowing interaction in Chronic Obstructive Pulmonary Disease (COPD) patients hospitalized in intensive care unit for an acute exacerbation, and evaluate the impact of using non invasive mechanical ventilation (NIV)
This is a prospective, observational, non-drug interventional, non-randomized study to compare the rate of moderate-severe COPD exacerbations in patients of all Chronic Obstructive Pulmonary Disease (COPD) severities with and without cardiovascular diseases. A total study population of 3330 subjects will be recruited by general practitioners (GPs) and assessed over a 27 month time frame.
Patients with Chronic Obstructive Lung Disease (COPD) often develop muscle problems, particularly in their legs which makes them more limited in what they can do. The Short Physical Performance Battery (SPPB) is a simple test of standing balance, usual walking speed and ability to stand from a chair. The SPPB may be a useful measure to predict leg function. This study aims to evaluate whether the SPPB is comparable with current exercise tests used in COPD patients, and whether it is useful in predicting disability, death and health resource usage over time.
The purpose of this study is to evaluate whether the introduction of large-scale telemonitoring of patients with COPD produces benefits in terms of improved health-related quality of life and reduced access to hospital facilities. In addition, the trial evaluates the economic and organisational impact of the new services, and examine their acceptability by patients and health professionals.
Background: In chronic obstructive pulmonary disease, the prognosis for patients who have survived an episode of acute hypercapnic respiratory failure due to an exacerbation is poor. Despite being shown to improve survival and quality-of-life in stable patients with chronic hypercapnic respiratory failure, long-term noninvasive ventilation is controversial in unstable patients with frequent exacerbations, complicated by acute hypercapnic respiratory failure. In an uncontrolled group of patients with previous episodes of acute hypercapnic respiratory failure, treated with noninvasive ventilation, we have been able to reduce mortality and the number of repeat respiratory failure and readmissions by continuing the acute noninvasive ventilatory therapy as a long-term therapy. Methods: Multi-center open label randomized controlled trial of 150 patients having survived an admission with noninvasive ventilatory treatment of acute hypercapnic respiratory failure due chronic obstructive pulmonary disease. The included patients are randomized to usual care or to continuing the acute noninvasive ventilation as a long-term therapy, both with a one-year follow-up period. End points: The primary endpoint is one-year mortality; secondary endpoints are time to death or repeat acute hypercapnic respiratory failure, number of readmissions and repeat acute hypercapnic respiratory failure, exacerbations, dyspnea, quality of life, sleep quality, lung function, and arterial gases.
