Filter by:In a former study, the investigator observed significant differences in the response to pulmonary rehabilitation between COPD patients with the "normal" genetic variant of alpha-1 antitrypsin (PiMM) and those with a homozygous deficient variant (PiZZ) (Jarosch et al., 2016, DOI: 10.1159/000449509). PiZZ COPD patients showed less improvement in exercise capacity compared to PiMM patients. This latter finding was mirrored by an increase of oxidative myofiber type I proportion - that is important for aerobic exercises in daily life - in PiMM but not PiZZ patients. Based on this finding of impaired skeletal muscle adaptation, the aim of this study is to compare the effects of pulmonary rehabilitation including exercise training on a) specific enzymes of energy metabolism reflecting the oxidative capacity of the skeletal muscle and b) the analogue gene expression of these oxidative enzymes in a cohort of PiMM and PiZZ COPD patients.
The purpose of this study is to determine the effectiveness of telemedicine multifaceted intervention in symptoms patients with chronic obstructive pulmonary disease.
This study aims to compare the impacts of two versions of a continuing education activity targeted at COPD case managers on educational outcomes: 1) participation; 2) satisfaction; 3) learning; 4) competence; 5) performance; 6) patient health outcomes.
This study will evaluate the effects of budesonide (using Symbicort which is budesonide and formoterol) and fluticasone (using Advair which is fluticasone and salmeterol) on the airway microorganisms of patients with moderate-to-severe chronic obstructive pulmonary disease (COPD). This is a randomized, parallel group, two-centered clinical trial study to evaluate the effects of a 12 week treatment with Symbicort 400 mcg BID and Advair 250 mcg BID (via Diskus) on airway microbiota in patients with moderate-to-severe COPD. The control arm of this study will be Oxeze 12 ug BID.
Current guideline-based criteria defining COPD do not meet the challenges set by the complex pathophysiology of the disease. The investigators therefore aimed to evaluate novel or not widely used diagnostic approaches for the detection and therapeutic monitoring of COPD.
Current diagnostic tools used in pulmonary disease often do not meet the challenges set by the respective pathophysiology. The investigators therefore aimed to evaluate novel or not widely used diagnostic approaches for the detection and therapeutic monitoring of patients with various pulmonary diseases.
The Aims of the study are estimate the association between the severity of COPD and free testosterone level and the prevalence of hypogonadism in adult men with stable COPD
Chronic Obstructive Pulmonary Disease (COPD) is characterized by chronic systemic hypoxia and low-grade inflammation as well as by an alteration of arginine (ARG) metabolism. As ARG is synthetized from circulating citrulline (CIT), an alteration of CIT homeostasis, particularly its production by ornithine transcarbamylase (OCT) in small intestine could be involved. We hypothesized that hypoxia +/- inflammation, classically associated to COPD, has effects on OCT regulation in enterocytes. This study aims at exploring the effects of hypoxia and inflammation on the production of citrulline by ornithine transcarbamylase (OTC) activity in enterocytes from explant cultures of duodenal tissue.
The prevalence of chronic respiratory disease, including chronic obstructive pulmonary disease (COPD), is increasing in industrialized countries. Over the next decade deaths from COPD are projected to increase by more than 30% and COPD will become the third leading cause of death worldwide by 2030. There is robust scientific evidence that non-invasive ventilation (NIV) therapy is an effective option for most COPD patients hospitalized with acute hypercapnic respiratory failure secondary to an acute disease exacerbation. More recently, NIV has been shown to significantly improve survival and quality of life in COPD patients with chronic stable hypercapnic disease. These data represent an important advance in the field, and indicate that usage of NIV in patients with chronic stable hypercapnic COPD should increase. Such an increase would be expected to improve patient outcomes and have a beneficial impact on the significant healthcare burden incurred by these patients. However, the proportion of stable COPD patients with chronic hypercapnia is unknown. In addition, using NIV at home to treat COPD patients with hypercapnic (type 2) respiratory failure has not often been considered previously and there is a paucity of data regarding NIV usage patterns over time in this setting. Phase2: There is robust scientific evidence that non-invasive ventilation (NIV) therapy is an effective option for most COPD patients hospitalised with acute hypercapnic respiratory failure secondary to an acute disease exacerbation [3]. More recently, NIV has been shown to significantly improve survival and quality of life in COPD patients with chronic stable hypercapnic disease [4] and in patients with persistent hypercapnia after an acute chronic respiratory failure [11]. Over the past two decades, the utilisation of NIV has become one of the most important developments in the field of mechanical ventilation. However, unsuccessful NIV was found to be independently associated with death [5] and poor NIV compliance was associated with higher risk of repeat acute NIV use [6]. There is a paucity of useful predictors of poor patient compliance and the performance of conventional algorithms for detecting COPD exacerbations is still weak. Detection of NIV failure is crucial in patient management in view of its negative effect on quality of life and prognosis and the fact that it often leads to hospitalisation. In addition, 70% of COPD-related healthcare costs are consequences of emergency and hospital stays for the treatment of exacerbations [7]. Recently, tele-monitoring emerged and unfolded differently among various healthcare organisations and countries. Evidence regarding its impact on the management of COPD patients is still insufficient to draw firm conclusions. Assumption has been made that remote monitoring of home NIV treatment could help to identify novel predictors of the early detection of NIV failure and deteriorations in patients with COPD. The incidence in routine clinical care of unplanned all-cause and COPD-caused hospitalisations in patients treated with NIV therapy who are continuously monitored by telemetric data in several European countries needs evaluation. In addition, predictors of unplanned all-cause and COPD-caused hospitalisations as well as of compliance and persistence to NIV therapy should be assessed in this patient population with special respect to continuous tele-monitoring
The COPD Patient-Powered Research Network (COPD PPRN) is a patient research registry with the goal of enrolling 75,000 or more COPD patients and those at risk who are willing to share their heath information over several years and participate in research. The COPD PPRN has built an online platform to allow volunteers to enroll electronically, complete surveys, be contacted about studies they qualify for and become connected to COPD resources. The goal of the registry is to speed research to find better treatments for COPD and ultimately a cure.
