Filter by:Investigation into the associations between sedentary behaviour, physical activity, body composition and cardiometabolic risk in COPD. A single assessment visit with fasting blood tests, body composition and strength measures followed by a week of activity monitor wear to record sitting time and physical activity. Cardiometabolic risk markers include fasting glucose, HBA1c, HOMA and lipids and blood pressure.
Randomized, placebo controlled trial evaluating efficacy of acetazolamide in preventing altitude related adverse health effects (ARAHE) in lowlanders with chronic obstructive lung disease travelling from 760 m to 3200 m.
Chronic obstructive pulmonary disease(COPD), characterized by persistent airflow limitation, associated with an progressive chronic inflammatory response of the lung to noxious particles or gases, can lead to dyspnea and limited mobility and influence the life quality of patients severely. Type 2 diabetes mellitus(T2DM), as a common complication of COPD, has got more attention in comprehensive control of COPD. Stress response and metabolic disorder are more likely to happen in COPD patients with T2DM in high level inflammation status, which decrease the drug efficacy, increase the risk of acute exacerbation of COPD, complications and mortality. Both COPD and T2DM are chronic inflammatory disease with long term, there is close relationship in occurrence and development of each other, and the patients with severe COPD are more likely to develop T2DM. Monitoring the acute inflammation maker of C reactive protein (CRP) and IL-6(interleukin-6) is the most useable way to predict the inflammatory status and condition of COPD patient with T2DM, however the chronic inflammation maker is lacking. Neutrophil-to-Lymphocyte ratio(NLR), platelet-lymphocyte ratio (PLR) and lymphocyte-monocyte ratio (LMR) , the new, cheap and easy-tested chronic inflammatory markers, have got great research in early predicting the tumor such as nasopharyngeal carcinoma, soft tissue sarcoma and small-cell lung cancer,among them, NLR has manifest promising application in predicting insulin-resistance. However the value about NLR,PLR and LMR to predict the T2DM in COPD patients remain unknown and many articles related to NLR and COPD are retrospective. The investigators attempt to analyze the risk factors and predict value of NLR,PLR and LMR about developing T2DM in COPD patients with prospective method.
This protocol describes a randomised controlled trial to test the hypothesis that 6 months of treatment with tiotropium and olodaterol will result in a reduction in bacterial load, an improvement in neutrophilic inflammation and clinical benefits compared with treatment with inhaled fluticasone furoate and vilanterol in patients with neutrophilic Chronic obstructive pulmonary disease (COPD). COPD is the third leading cause of death worldwide and a major cause of morbidity in the UK. Exacerbations drive disease progression and worsening quality of life and therefore prevention of exacerbations has been a major goal of treatment. In recent years, attempts have been made to phenotype COPD patients in order to target therapies to the correct groups of patients that will benefit. Inhaled corticosteroids (ICS) are primarily effective for patients with eosinophilic inflammation, while there are few established therapies for patients with neutrophilic disease. In recent years, all ICS preparations have been associated with a significant increased risk of pneumonia and this risk appears to be greatest in patients with non-eosinophilic inflammation. Combined treatment with long acting beta-agonists (LABA) and long acting muscarinic antagonists (LAMA) combinations appears to be a safer and more effective alternative for patients with non-eosinophilic disease. The combination of tiotropium and olodaterol in particular, has strong preclinical data supporting beneficial effects on neutrophilic inflammation. The trial is a multi-centre randomised open label controlled parallel group study with two treatment arms in 80 participants. Moderate to very severe COPD patients and currently treated with inhaled corticosteroid therapy will be randomised to treatment with either the combination of tiotropium and olodaterol (LABA/LAMA) or fluticasone furoate and vilanterol (ICS/LABA). Participants will return at 1 month, 2 months, 3 months and 6 months for sampling of the lower airway by sputum samples and the upper airway using oropharyngeal and nasopharyngeal swabs. Sputum will be used to test for airway neutrophilic inflammation. This study will make an important contribution to understanding "phenotyping" in COPD by identifying whether the combination of tiotropium and olodaterol improves airway bacterial load and restores neutrophil function in patients with neutrophilic COPD.
Objectives: Investigate the acute NIV effects on CBF and cognitive functions in COPD patients. Methods: Nine non-hypercapnic stable COPD subjects (FEV1/FVC < lower limit of normal) and twelve healthy controls were enrolled. CBF (transcranial Doppler), cognitive functions, respiratory and cardiovascular response were tested at baseline, during and after non-invasive ventilation.
Previous population health studies suggest that up to 10% of Canadian adults have undiagnosed asthma or COPD- these people are currently undiagnosed and untreated, even though they may have significant respiratory symptoms. Our study will use targeted casefinding to find people with undiagnosed asthma and COPD in Canadian communities. The investigators will assess their symptoms and their health care use and number of sick days to determine the burden of undiagnosed respiratory disease in these people. The investigators will then determine whether early treatment of previously undiagnosed airflow obstruction will improve patients' health outcomes.
Neutrophil CD64 versus Neutrophil/Lymphocyte ratio (NLR) as markers predicting in-hospital outcome in acute exacerbation of COPD
This study evaluates the implementation of an education protocol and its impact on the correct inhalation technique in COPD patients presenting errors or mistakes. There will be 4 sessions, in each one the inhalation technique will be evaluated using a checklist of steps. Whenever errors are found, the correct use of each device will be educated through verbal explanation and written material will be delivered.
The purpose of this study is to show bioequivalence of test product to reference product based on baseline-adjusted forced expiratory volume in one second (FEV1).
Chronic Obstructive Pulmonary Disease (COPD) is a common smoking related lung disease. The main symptom in breathlessness. Pulmonary Rehabilitation (PR) - a supervised group exercise and education class - is an effective intervention in COPD to reduce symptoms, improve exercise performance and prevent exacerbations. However some COPD patients are unable to to effectively exercise as they are limited by their breathlessness, despite optimal medical management. By reducing their physical activity to avoid the onset of breathlessness, they become deconditioned and then further attempts at exercise make them more breathless, leading to an inactivity cycle. There is a growing evidence base regarding the use of hand hold fan therapy or air therapy to relieve breathlessness at rest. Limited studies have looked at the use of fan therapy during exercise, and its role on exercise capacity and recovery time, provisional results which indicate it may also be useful during activity. Logically you might expect patients who are less breathless to be able to exercise more, or recover quicker. This study aims to investigate the effects a hand held fan will have on sensation of breathlessness and exercise capacity in patients with COPD. This will involve participants undertaking a standardised field walking test ( 6 minute walk test) with and with out the fan and then comparing the distance covered and how they felt during and after exercise. This will better inform how we structure exercise and advice to these patients in the future to empower patients limited by breathlessness.
