Active clinical trials for "Pulmonary Disease, Chronic Obstructive"

Humidified Nasal High-flow with Oxygen (HNHF-O2) therapy has been reported to have acute beneficial effects in patients with hypoxemic respiratory failure who have been hospitalized. The usefulness of this therapy in the outpatient setting is unproven. This pilot study will test the feasibility of using this therapy in the outpatient setting and its effects on sleep.

This single and repeat increasing dose study will collect information on safety, tolerability and drug levels in the body of the CCI15106 inhalation powder. The study will also look at the level of CCI15106 that will be released into the air and may be found in the blood of the people standing around the person inhaling it (bystanders). This is a two-part study in which Part 1 will enroll healthy subjects and look at environmental and bystander exposure and Part 2 will enroll subjects with moderate COPD. Approximately 36 healthy subjects and approximately 22 subjects with COPD will be randomized in this study for dosing. The total study duration will be 82 days for Cohort A Part 1; 75 days for Cohort B Part 1 and Cohort C Part 1; 77 days for Cohort A Part 2; and 90 days for Cohort B Part 2.

Chronic obstructive pulmonary disease (COPD) is a major health problem. Acute exacerbations are a health-care burden involving frequent hospitalizations and elevated costs. They have effective therapies with significant side effects. Acupuncture has been shown to reduce dyspnea and other COPD-related symptoms. The investigators will compare the efficacy and safety of the addition of true acupuncture to usual care with both sham-acupressure added to usual care and usual care only for the treatment of acute exacerbations of COPD among inpatients.

Patients with COPD (chronic bronchitis and/or emphysema) are known to be at an increased risk of heart disease and death due to heart attacks. There are several possible reasons for this, one of which is an increased tendency of the blood to clot, that can give rise to blood clot formation in the coronary arteries, and lead to heart attack. Medications such as Aspirin and another new blood thinning tablet called Ticagrelor are already used for patients with heart attacks. Given that patients with COPD are at higher risk of heart attack, the investigators wish to see if these tablets that can prevent blood clot formation in heart arteries might also prevent heart attacks happening in COPD patients. The investigators hope to understand the effects by measuring clotting and inflammation in the blood. All patients will be followed up for 6-months. In addition the investigators wish to study COPD patients who do not have a high risk of developing future heart problems using the QRISK score to study their well being over a 1 year period to see if they might also benefit from blood thinning medications.

The purpose of this project is to validate quantitative lung structure assessment using an automated analysis software (VIDA), for application to low dose computed tomography (LDCT) acquired for lung cancer screening. Currently the software runs on standard dose CT data. In addition, it is the plan to incorporate algorithms into the software to address assessment of any identified pulmonary lesions.

The aim of this interventional, randomized, double-blind, monocentric, cross-over study is to quantify the possible deleterious effect on the cardiac autonomic nervous system control of two long-acting anticholinergic bronchodilatators (tiotropium and glycopyrronium) and one beta-2 agonist long-acting bronchodilatator (indacaterol ) in patients with mild COPD.

The study hypothesis is that symptomatic current and former smokers with spirometric values within the normal range (post-bronchodilator FEV1/FVC≥0.70 and post-BD FVC ≥ 70% predicted will still derive symptomatic benefit from long-acting bronchodilator therapy even though they are excluded from current GOLD guideline recommendations.

Structural changes in skeletal muscles of patients with chronic obstructive pulmonary disease (COPD) have been linked to impaired muscle function, reduced exercise capacity, and increased mortality associated with this disease. Muscle dysfunction also contributes to dyspnea intensity and the ability to sustain exercise, making aerobic exercise training intolerable at the intensity and/or volume required to achieve clinically important changes. Resistance training (RT) is an attractive exercise modality because it is efficacious and more tolerable initially. No work has examined whether a short-term RT program can reduce exertional symptoms and improve exercise tolerance (dyspnea and leg fatigue) in patients with COPD.

To assess the effect of treatment with Glycopyronnium (GP) MDI administered twice daily (BID) and Formoterol Fumarate (FF) MDI administered BID on specific image-based airway volumes and resistance in subjects with moderate to severe chronic obstructive pulmonary disease (COPD) following chronic dosing after approximately two weeks treatment.

The purpose of this study is to assess the activation patterns of diaphragm and sternocleidomastoid (SCM) muscle during different loaded inspiratory muscle performance in patients with COPD after acute exacerbation. Null hypothesis (H0): There is no significant difference between activation pattern of diaphragm and SCM muscle during different loaded inspiratory muscle performance in patients with COPD after acute exacerbation. Alternative hypothesis (H1): There is significant difference between activation pattern of diaphragm and SCM muscle during different loaded inspiratory muscle performance in patients with COPD after acute exacerbation.
