Filter by:Non-invasive ventilation (NIV) in severe hypercapnic Chronic Obstructive Pulmonary Diseases (COPD) may be associated - during sleep - with recurrent episodes of patient ventilatory asynchrony, which in turn may affect quality of sleep, efficacy of ventilation and comfort of nocturnal NIV.Polysomnography (PSG) under NIV is necessary to detect these events. Adjusting ventilator settings according to respiratory events detected by PSG with NIV may improve quality of sleep, efficacy of ventilation and comfort of nocturnal NIV.
The purpose of this study is to determine whether telehealth nursing consultations of chronic obstructive pulmonary disease (COPD) patients are superior to hospital readmissions.
Chronic obstructive pulmonary disease (COPD) is often caused by cigarette smoking, but genetic predisposition also influences COPD susceptibility. The purpose of this study is to identify genetic factors that predispose some individuals to develop COPD.
The purpose of this study is to evaluate the safety and the efficacy of Glycopyrrolate as pMDI after single and repeated administration.
This is a parallel group, double-blind, placebo controlled, multi-centre, randomised trial. 60 patients to be included who are adult patients admitted to hospital with a clinical diagnosis of acute exacerbation of Chronic Obstructive Pulmonary Disease (COPD). Acute exacerbation of COPD will be defined as sustained worsening of the patient's condition with an increase in cough and one or more of dyspnoea, sputum volume or sputum purulence, necessitating a change in regular medication. The primary objective of this study is to evaluate the effectiveness of standard care plus erdosteine in reducing hourly cough (24 hour cough recording using automated cough recorder) measured from baseline (Day 0) and at Day 5 of treatment, compared with standard care plus placebo.
Conventional pulmonary rehabilitation programs improve exercise tolerance, peripheral muscle strength, and health related quality of live but not pulmonary function in patients with chronic obstructive pulmonary disease (COPD). The role of breathing retraining techniques in the rehabilitation of patients with COPD remains unclear. The hypothesis to be tested in this study is that pulmonary function, cardio-pulmonary exercise capacity, health related quality of life and cardiac autonomic modulation of patients with COPD who undergo pulmonary rehabilitation plus breathing retraining will be better than that of patients undergoing a conventional pulmonary rehabilitation.
The aim of the study is to compare the efficacy and tolerance of autotitrating non-invasive ventilation (NIV) versus standard NIV in patients admitted to hospital with acute exacerbation of chronic respiratory failure. The investigators hypothesise that autotitrating NIV will ventilate patients with acute exacerbations of chronic respiratory failure as effectively as standard NIV.
Weight loss commonly occurs in patients with chronic obstructive pulmonary disease (COPD), negatively influencing their quality of life, treatment response and survival. Loss of muscle protein is generally a central component of weight loss in COPD patients. Attempts to reverse muscle loss in COPD by supplying large amounts of protein or calories to these patients have been unsuccessful. Gains in muscle mass are difficult to achieve in COPD unless specific metabolic abnormalities are targeted. The investigators recently observed that alterations in protein metabolism are present in normal weight COPD patients. Elevated levels of protein synthesis and breakdown rates were found in this COPD group indicating that alterations are already present before muscle wasting occurs. Furthermore, reduced plasma essential amino acid (EAA) levels were observed in COPD patients. These reduced EAA plasma levels were significantly related with the presence of muscle wasting in COPD. Until now, limited research has been done examining protein metabolism and the response to feeding in patients with COPD. Previous studies support the concept of essential amino acids (EAA) as an anabolic stimulus in the young and elderly and in insulin resistant states. Until yet no information is present on the anabolic effects of EAA in elderly COPD patients. It is therefore our hypothesis that a high-leucine essential amino acids mixture specifically designed to stimulate protein anabolism will target the metabolic alterations of COPD patients. In the present study, the acute effects of an EAA nutritional supplement on whole body, muscle and liver protein metabolism will be examined in COPD patients and compared to a supplement consisting of a balanced mixture of total amino acids. The principal endpoints will be the extent of stimulation of whole body protein synthesis as this is the principal mechanism by which either amino acid or protein intake causes muscle anabolism, and the reduction in endogenous protein breakdown. Both endpoints will be assessed by isotope methodology which is thought to be the reference method.
Pursed-lip breathing (PLB) has been advocated to reduce respiratory rate and improve oxygen saturation in patients with chronic obstructive pulmonary disease (COPD) at rest. Although PLB is a strategy that potentially reduces expiratory flow limitation, there are only few studies addressing its effects on exercise. This study aimed to assess the ability of PLB to change the breathing pattern, degree of dynamic hyperinflation (DH) and arterial oxygenation in COPD patients during exercise. Exercise tolerance was evaluated by endurance time and respiratory mechanics was evaluated by forced oscillation technique.
The purpose of this study is to evaluate health status of uncontrolled Chronic Obstructive Pulmonary Disease (COPD) patients in response to treatments in clinical practice.
