Filter by:Chronic Obstructive Pulmonary Disease (COPD) is a progressive disease that is characterized by loss of lung function, leading to breathlessness, poor quality of life, loss in productivity, and increased mortality. The World Health Organization estimates that COPD will be the third leading cause of death worldwide by 2020, accounting for more than 7 million deaths annually. COPD patients frequently experience 'lung attacks', during which breathlessness, coughing, and sputum production dramatically increase, leading to urgent office visits, emergency admissions and hospitalizations. Lung attacks reduce patient quality of life and cost the Canadian health care system nearly $4 billion dollars each year in direct and indirect costs. Lung attacks can be effectively managed if they are identified and treated early, but symptoms of a lung attack often overlap with those of other common conditions such as heart failure, pneumonia and even influenza. Because there are no tests that can separate lung attacks from these conditions, doctors struggle to accurately diagnose lung attacks at an early stage when drugs are most effective. This can lead to a delayed or even incorrect diagnosis and inappropriate treatment. This research will address this critical need. Our goal is to improve COPD patient care by developing new blood tests that will help identify patients who are in the early stages of a lung attack. Doctors will be able to use these tests to treat lung attacks at earlier stages than is currently possible. These blood tests will enable doctors to personalize management of COPD to meet the needs of the individual patient. Hypothesis: New biomarker blood tests can be used to better identify and manage patients with COPD.
Chronic obstructive pulmonary disease is a chronic condition involving an impairment in functionality and in the execution of activities of daily life. The hypothesis of this study is that an occupational therapy intervention added to a physiotherapy program and a medical treatment increase the functionality and the quality of life of patients with chronic obstructive pulmonary disease.
Study hypothesis: Chronic Obstructive Pulmonary Disease (COPD) patients with chronic bacterial colonization have lower levels of mucins and antimicrobial peptides in their airways
SPIROMICS I and SPIROMICS II are observational studies of Chronic Obstructive Pulmonary Disease (COPD). SPIROMICS I had two main aims: (1) To find groups of patients with COPD who share certain characteristics; (2) To find new ways of measuring whether or not COPD is getting worse and so provide new ways of testing whether a new treatment is working. SPIROMICS II has three primary aims. Aim 1 is to define the natural history of "Smokers with symptoms despite preserved spirometry" and characterize the airway mucus abnormalities underlying this condition. Aim 2 is to determine the radiographic precursor lesion(s) for emphysema, and identify the molecular phenotypes underlying airway disease and emphysema. Aim 3 is to advance understanding of the biology of COPD exacerbations through analysis of predisposing baseline phenotypes, exacerbation triggers and host inflammatory response.
The chronic obstructive pulmonary disease (COPD) is the occurrence of chronic bronchitis or emphysema, a pair of commonly co-existing diseases of the lungs in which the airways narrow over time. This limits airflow to and from the lungs, causing shortness of breath (dyspnoea). In clinical practice, COPD is defined by its characteristic airflow limitation on lung function tests. In contrast to asthma, this limitation is poorly reversible and usually gets increasingly worse over time. The COPD registry is a non-interventional multicentre observational prospective database focusing on the collection and analysis of data on real mortality and morbidity in COPD population of the Czech Republic population of COPD patients. Monitoring is done at the occasion of regular check-ups, followed by retrospective search of data in the documentation, and a record into the registry. The aim of Czech National Research Database of Chronic Obstructive Pulmonary Disease is to establish the clinical course of severe forms of COPD, establish the cause for deterioration of clinical status of our patients and describe the progression of COPD to death. The registry fulfils general objectives of health registries such as monitoring of causes, development, treatment and consequences of a severe disorder, including economic and social impacts. Statistical and scientific analyses of the registry data are focused, in particular, on the assessment of health determiners of the selected patient cohort with the aim to improve health status of the patients.
Background The Swiss health ministry launched a national quality program "QualiCCare" in 2011 to improve healthcare for patients with COPD. The aim of this study is to determine whether participation in the COPD quality initiative ("QualiCCare") improves adherence to recommended clinical processes and shows impact on patients COPD care and on quality of life in patients with COPD.
The purpose of the study is to evaluate the efficacy and safety of a biological vaccine (MV130 in subjects with Chronic Obstructive Pulmonary Disease (COPD) compared with a placebo group.
The main aim of this multicentric 5-year follow-up study is to evaluate for the first time the long-term efficacy and safety (in terms of smoking-related serious diseases requiring hospitalization) of e-cigarette smoking, comparing its health effects with those of traditional cigarette smoking and mixed electronic and traditional cigarette smoking. The study will also permit to evaluate, over a 5-year follow-up, the self-reported quality of life, and the reported adverse events according to current and past smoking habit. Finally, the study will also explore the long-term adherence to e-cigarette smoking and its efficacy of e-cigarettes in reducing and/or quitting traditional cigarette smoking.
Our primary hypothesis is that Roflumilast (500 μcg, once daily) will significantly decrease surrogate markers of bone metabolism and early cardiovascular disease in individuals with moderate to severe airflow obstruction and a chronic bronchitis phenotype.
Loss of muscle protein is generally a central component of weight loss in Chronic Obstructive Pulmonary Disease (COPD) patients. 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. The investigators recently observed that in order to enhance protein anabolism, manipulation of the composition of proteins and amino acids in nutrition is required in normal-weight COPD. Intake of casein protein resulted into significant protein anabolism in these patients. The anabolic response to casein protein was even higher than after whey protein intake. A substantial number of COPD patients, underweight as well as normal weight to obese, is characterized by an increased inflammatory response. This group failed to respond to nutritional therapy. Previous experimental research and clinical studies in cachectic conditions (mostly malignancy) indicate that polyunsaturated fatty acids (PUFA) are able to attenuate protein degradation by improving the anabolic response to feeding and by decreasing the acute phase response. Eicosapentaenoic acid (EPA) (in combination with docosahexaenoic acid (DHA)) has been shown to effectively inhibit weight loss in several disease states, however weight and muscle mass gain was not present or minimal. Until now, limited research has been done examining muscle protein metabolism and the response to EPA and DHA supplementation in patients with COPD. It is the investigator's hypothesis that supplementation of 2g/day EPA+DHA in COPD patients during 4 consecutive weeks will increase the muscle anabolic response to a high quality protein supplement as compared to a placebo, and supplementation of 3.5g/day EPA+DHA will increase the anabolic response even further. In the present study both the acute and chronic effects of EPA+DHA versus a placebo on muscle and whole body protein metabolism will be examined. The principal endpoint will be the extent of stimulation of net fractional muscle protein synthesis as this is the principal mechanism by which the effect of EPA+DHA on muscle anabolism can be measured. The endpoint will be assessed by isotope methodology which is thought to be the reference method.
