Filter by:The purpose of this 3 month randomized intervention study is to investigate the additional effect of a physical activity telecoaching program on physical activity in patients with COPD, compared with usual care.
Comparing the efficacy of Symbicort® pMDI and Formoterol Turbuhaler in reducing exacerbations in patients with Chronic Obstructive Pulmonary Disease (COPD).
Obstructive sleep apnea (OSA) is the most common type of sleep apnea and is caused by an obstruction of the upper airways. The obstruction results in periods of intermittent hypoxia and re-oxygenation, which lead to increased oxidative stress, increased inflammation, endothelial dysfunction, and insulin resistance. Chronic obstructive pulmonary disease (COPD) is a lung disease that leads to poor airflow. This disease leads to systemic hypoxia, reduced oxidative capacity, and increased inflammation. The direct cause of OSA and COPD is unclear, but OSA and COPD may be linked to other comorbid conditions such as obesity and type II diabetes. Upon onset of OSA and COPD, metabolic disturbances associated with obesity and type II diabetes can be exacerbated. Obesity is a condition characterized by an increase in visceral fat, elevated plasma levels of free fatty acids, inflammation, and insulin resistance. Although the effects of body fat distribution have not been studied in these patients, an increase in both subcutaneous and abdominal fat mass in non-OSA older women was shown to increase morbidity and mortality. Fat/adipose tissue is an active tissue capable of secreting proinflammatory cytokines such as tumor necrosis factor (TNF)-alpha and interleukin (IL)-6, reactive oxygen species and adipokines. Particularly, abdominal fat is a prominent source of pro-inflammatory cytokines, which contributes to a low grade, chronic inflammatory state in these patients. Additionally, an increased inflammatory state is associated with reduced lean body mass, and together with elevated circulating free fatty acids may increase the occurrence of lipotoxicity and insulin resistance. Thus, increased fat deposition is associated with a poor prognosis in OSA and COPD patients and therefore it is of clinical and scientific importance to understand the changes in fat metabolism and digestion as a result of OSA and COPD. It is therefore our hypothesis that fat synthesis and insulin resistance is increased and whole body protein synthesis is decreased in OSA and COPD patients, leading to a poor prognosis.
The aim of this study is to assess the efficacy of a rehabilitation protocol based on individualized combined eccentric and concentric cycle ergometer training compared to classical concentric cycle training among patients with either coronary artery disease (CAD) or chronic obstructive pulmonary disease (COPD). This study will therefore evaluate the efficacy of combined eccentric/concentric training on physical capacity and overall autonomy, and will analyse the adaptive mechanisms with regard to both adaptation to cardiac and muscular effort and tolerance.
The purpose of the study is to determine if benralizumab reduces COPD exacerbation rate in symptomatic patients with moderate to very severe COPD who are receiving standard of care therapies.
The purpose of this study is to assess the effect of aclidinium bromide compared with placebo in improving dilatation of the airways (bronchodilation), symptoms of chronic obstructive pulmonary disease (COPD), sleep quality and physical activity after 3 weeks of treatment with aclidinium bromide 400 μg administered twice daily in patients with stable moderate-and-severe COPD.
This study is a 12-week, multicenter, randomized, double blind, parallel group, placebo-controlled study. The purpose of this study is to replicate the therapeutic benefit of UMEC/VI 62.5/25 microgram (mcg) on health-related quality of life as reflected by St. George's Respiratory Questionnaire (SGRQ) scores and symptoms as reflected by rescue medication use observed in the 6 month placebo controlled study (DB2113373). Lung function will be assessed as it provides an objective measure to support the subjective patient reported outcomes of SGRQ and rescue medication use. The study is intended to provide additional evidence to support the use of UMEC/VI for the maintenance treatment of COPD Approximately 496 subjects will be randomized from approximately 62 centers in order to ensure 422 subjects complete 12 weeks of treatment. Eligible subjects will be randomized to UMEC/VI 62.5/25mcg or placebo in a 1:1 ratio. All treatments will be administered once-daily in the morning via a Dry Powder Inhaler (DPI). There will be a total of 5 clinic visits. The total duration of study participation will be approximately 15 weeks. All subjects will be provided with albuterol/salbutamol to use as needed for the relief of COPD symptoms throughout the run-in and double-blind treatment periods.
The purpose of this study is to investigate the effect of nocturnal oxygen therapy during a stay at moderate altitude on breathing and sleep of patients with chronic obstructive lung disease.
Long-term NRT has not been studied in patients with COPD, and smokers in the United States with COPD are still asked to choose between immediate quitting or continued smoking. The purpose of this study is to see if guided maintenance therapy (GMT), using long-term NRT, might prove to be a reasonable alternative to the standard approach of asking patients to quit immediately. The investigators believe that GMT with long-term NRT will reduce overall exposure to cigarette smoke, reduce harm related to smoking, and ultimately lead to greater quit rates. In this study, 398 smokers with COPD will be randomly assigned to either receive: 1) traditional smoking cessation (SC) or 2) long-term, guided maintenance therapy with NRT (GMT). The SC intervention will be based on a standard approach to smoking cessation, including smoking cessation counseling supplemented with combination NRT (a nicotine patch plus the patient's choice of gum or lozenge) if they are willing to make a quit attempt. The GMT intervention will consist of counseling, focused on medication adherence and smoking reduction, plus 52 weeks of combination NRT. After 3, 6 and 12 months of treatment, we will compare the two treatments based on their effects on smoking cessation, number of cigarettes smoked, exposure to carbon monoxide and smoking-related carcinogens, COPD symptoms, breathing function, and smoking-related hospitalizations or death. The investigators will also analyze the data in such a way that will be able to identify which patients are most likely to benefit from treatment. This analysis will allow patients to estimate their chances of success based on their own personal characteristics and which treatment they choose. The investigators study addresses research priorities identified in recent smoking cessation guidelines and builds upon the input of our Patient Advisory Panel and our Stakeholder Advisory Committee. This study reflects the interests expressed by smokers in prior surveys and addresses the limited reach and effectiveness of traditional approaches to smoking cessation. If our GMT approach is effective, our study could change the recommendations provided in clinical practice guidelines and change the way that insurance companies pay for smoking cessation treatment. GMT could provide an alternative for millions of smokers with COPD who are not currently benefiting from traditional approaches to smoking cessation
The hypothesis is that in acute exacerbated Chronic Obstructive Pulmonary Disease (AECOPD), personalized variable dose glucocorticoid treatment will result in superior clinical outcome when compared to fixed dose therapy.
