Active clinical trials for "Lung Diseases, Obstructive"

Background: Non-invasive ventilation (NIV) reduces respiratory load and demands on peripheral muscles. Methods: This study aims to evaluate the acute effects of bi-level NIV on peripheral muscle function during isokinetic exercise and aerobic performance in chronic obstructive pulmonary disease (COPD) patients. This is a pilot crossover study performed with a non-probabilistic sample of 14 moderate to very severe COPD patients. Procedures carried out in two days. Dyspnea, quality of life, lung function, respiratory muscle strength, functional capacity (6-minute walk test - 6MWT), and isokinetic assessment of the quadriceps were assessed. Blood samples (lactate, lactate dehydrogenase, and creatine kinase concentration) were also collected. Right after, NIV was performed for 30 minutes (bi-level or placebo, according to randomization) followed by new blood sample collection, 6MWT, and isokinetic dynamometer tests. Before and after evaluations, the subjective perception of dyspnea and fatigue in the lower limbs was quantified. After a wash-out period of seven days, participants returned, and all assessments were performed again.

the study aims to investigate effectiveness of thoracic cage mobilizations on the chronic obstructive pulmonary diseases.

The aim of our study is to compare the effectiveness of the supervized pulmonary telerehabilitation program and the cognitive telerehabilitation method, which includes pulmonary telerehabilitation methods, in patients with severe stage COPD who have difficulty exercising heavily. The effects of pulmonary and cognitive rehabilitation on dyspnea, muscle strength, functional capacity, quality of life, anxiety and depression levels in this patient group will be examined. The number of studies in the literature in which the pulmonary rehabilitation program was applied as telerehabilitation is insufficient. Considering that this patient group is not motivated and has difficulty in exercising, motor imagery and movement observation methods from cognitive rehabilitation methods may be alternative methods for these patients. Although these methods have been very popular in recent years in terms of researching and demonstrating their effectiveness in various patient groups in the literature, no study has been found in which the effects of these methods have been applied in pulmonary disease groups. This study aims to contribute to the serious gap in the literature on the application of pulmonary telerehabilitation and its effectiveness, and to be an original study by investigating the effectiveness of motor imagery and action observation, which are popular rehabilitation methods of recent years, in COPD patients in the pulmonary disease group for the first time.

The purpose of this study is to investigate the short-term effects of two different breathing techniques (the active cycle breathing technique (ACBT) and the pursed lip breathing technique (PLB)) with Thera PEP® on the clearance of secretions and the oxygen saturation of individuals who have recently experienced an acute exacerbation of chronic obstructive pulmonary disease (COPD) in individuals who have recently experienced an acute exacerbation of COPD (COPD). Thirty patients will each have an acute COPD exacerbation seen on them, and then they will be randomly allocated to one of two groups (1. ACBT and PLB; 2. Thera PEP). Participants in a study employing a design known as a within-subject randomized crossover will be given the instruction to carry out each procedure on consecutive days as part of the study. In this study, the dependent variables will include blood pressure, heart rate, oxygen saturation (SpO2), respiratory rate, peak expiratory flow rate (PEFR), visual analog scale (VAS), sputum volume, and the breathlessness, cough, and sputum scale. In addition, the independent variables will include sputum volume (BCSC). The patient's desired course of treatment will also be taken into account. These dependent variables will be examined at three distinct moments in time: at the beginning of the study (the baseline), immediately after treatment, and thirty minutes after treatment has been completed.

Study to Assess the Safety and Tolerability of PT010, PT009 and PT003 in Subjects with Moderate to Very Severe Chronic Obstructive Pulmonary Disease

People with Chronic Obstructive Pulmonary Disease (COPD) suffer from dyspnoea, which may be exacerbated by psychological outcomes including anxiety and depression. Previous studies suggest that relaxation techniques may have positive effects on pulmonary rehabilitation. The main aim of this study is to explore both the respiratory and psychological impact of a quick, one-session, relaxation training for people with Chronic Obstructive Pulmonary Disease (COPD).

The purpose of this study was to assess global ventilated lung volume in moderate to severe COPD patients using MRI lung imaging after treatment with QVA149 compared to placebo.

This multicenter study will be conducted to compare the effect of FF/UMEC/VI with FF/VI plus UMEC on lung function after 24 weeks of treatment. This is a phase IIIB, 24-week, randomized, double-blind, parallel group multicenter study. This study will test the hypothesis that the difference in trough forced expiratory volume in one second (FEV1) between treatment groups is less than or equal to a pre-specified non-inferiority margin. Alternatively, this study will also test the hypothesis that the difference between treatment groups is greater than the margin. The triple therapy of FF/UMEC/VI in a single inhaler is being developed with the aim of providing a new treatment option for the management of advanced Global Initiative for Chronic Obstructive Lung Disease (GOLD) Group D COPD which will reduce the exacerbation frequency, allow for a reduced burden of polypharmacy, convenience, and improve lung function, health related quality of life (HRQoL) and symptom control over established dual/monotherapies. This study has a 2 week run in period where subjects will continue to have their existing COPD medications. At randomization, subjects will discontinue all existing COPD medications and will be assigned to treatment of FF/UMEC/VI, 100 microgram (mcg)/62.5 mcg/25 mcg and placebo or FF/VI, 100 mcg/25 mcg and UMEC, 62.5 mcg in a 1:1 ratio for 24 weeks. Subjects will have clinical visits at Pre-Screening (Visit 0), Screening (Visit 1), Randomization (Week 0, Visit 2), Week 4 (Visit 3), Week 12 (Visit 4) and Week 24 (Visit 5). A follow-up visit will be conducted at 1 week after the end of treatment period or after early withdrawal visit. Approximately, 1020 subjects will be enrolled in this study. There will be two pharmacokinetic (PK) groups (subset A and subset B). Approximately 120 subjects will be assigned to subset A and approximately 60 subjects will be assigned to subset B. The total duration of subject participation will be approximately 27 weeks, consisting of a 2-week run-in period, 24-week treatment period and a 1-week follow-up period.

The aim of this study was to compare the tiotropium Respimat Soft Mist Inhaler and the HandiHaler in terms of their effects on sleeping oxygen saturation (SaO2) and sleep quality in patients with COPD.

What are the differential effects of beta-blockers on lung and heart function during exercise in chronic obstructive pulmonary disease (COPD)? COPD is a major cause of illness and death. Not only do these individuals suffer from lung disease, but COPD often leads to other illnesses, particularly heart disease. Beta-blockers very successfully treat heart disease. It is therefore logical that one would want to use this treatment in COPD patients with heart disease too. However, there has always been concern that beta-blockers could cause significant problems in COPD by worsening lung function, as these can have the opposite effect to inhalers used to treat COPD that open up airways. Pointedly, there is increasing evidence that despite this problem, COPD patients who have been prescribed beta-blockers have been shown to gain benefit particularly in terms of preventing death. In this study, the investigators therefore want to examine which beta-blocker might be the safest for COPD patients, as each work slightly differently. Some beta-blockers may have a more beneficial effect on airways than others, whilst still benefitting the heart. The investigators will study two different beta-blockers; one that potentially narrows airways and one that potentially opens airways. The investigators will be using cardiopulmonary exercise testing (an exercise bike that measures both heart and lung function during exercise) to look for differences between both beta-blockers primarily in terms of lung function but also with information about the heart. The investigators will recruit people with moderate to severe COPD who are able to complete a cycle exercise test through their respiratory research department. The study will last for 10-12 weeks with 5 main visits to the department for serial exercise tests, breathing tests, simple heart function tests and simple blood tests that will tell the investigators what other effects these beta-blockers are having on the heart and lungs.
