Filter by:This is a Phase III randomized, double-blind, parallel group, multi-center, 52-week COPD exacerbation and lung function study with PT009 320/9.6 μg, PT009 160/9.6 μg and PT005 9.6 μg, all administered BID.
This investigation is designed to evaluate the performance, comfort and ease of use of the Simplus and Eson masks amongst NIV patients who are currently on Bi-level therapy
The aim of the study is to estimate the prevalence of respiratory aspiration in patients with COPD, in a tertiary hospital of Buenos Aires.
The purpose of this study is to conduct a pilot study to evaluate the safety and efficacy of weekly administration of Alpha1-Proteinase Inhibitor (A1PI) augmentation therapy in subjects with A1PI deficiency and emphysema/ chronic obstructive pulmonary disease (COPD).
The primary purpose of the study is to investigate if physical exercise is associated with myocardial damage, expressed by elevated troponin T, in patients with COPD.
Acute exacerbations of COPD contribute to significant morbidity and mortality in the United Kingdom (UK). The ability to assess response to treatment during exacerbations that require hospitalisation would allow clinicians to better risk stratify patients for higher or lower level in-patient or out-patient care. Current methods of detecting clinical deterioration are validated in general medical populations and may lack sensitivity and specificity in patients with respiratory morbidity. The use of respiratory muscle EMG to assess neural respiratory drive (NRD) has been demonstrated to be a predictor of readmission in patients admitted to hospital with COPD. The technique has been applied on 'spot' readings of limited duration due to the need for hand analysis of the data. It has been performed by a trained clinical physiologist who removed any interference data and standardised the data gathered. New automated software allows for longer periods of observation, mostly unsupervised, and as a result, the NRD measurements are more likely to be affected by various sources of variability. The influence of clinical and physiological factors as they occur during routine clinical management, such as administration of bronchodilator medication, time of day of readings or proximity to chest physiotherapy, are not yet understood. This trial is designed to gather data to better understand these relationships with NRD.
Breathlessness is an overwhelming symptom affecting tens of thousands of Australians every day. For many people, it persists even when all the underlying causes have been optimally managed (chronic breathlessness). In these circumstances, it often occurs at rest or with minimal exertion. Evidence from a number of clinical studies suggests that a small, regular dose of morphine helps to reduce safely the sensation of breathlessness. However, it is not well established which patients derive more benefit and what is the net clinical effect of this treatment (weighing benefits and harms). This is a phase III, multi-site, randomised, double-blind, placebo-controlled trial with patients with chronic obstructive pulmonary disease (COPD) and severe chronic breathlessness which will explore several important questions: - Are regular, low doses of morphine at four possible doses over 3 weeks more effective than placebo at improving breathlessness? - Does increasing the dose in people who already are experiencing some benefit provide even greater reduction in worst breathlessness? - Does the medication have any effect on daily activity and quality of life? - What are the common or serious side effects of this intervention? - Does the benefit from the medication outweigh the side effects it produces? - Are there specific characteristics of people who are more likely to receive benefit from extended release morphine? Participants will receive once daily extended release morphine (plus laxative, docusate with senna), or placebo (placebo laxative) in addition to their usual medication for up to 3 weeks at increasing doses. Participants will have a medical interview and physical examination to collect some general health information, and baseline measurements including; daily activity, symptoms, and quality of life. A small amount of blood may be required to check eligibility. Further blood samples may be taken at week 1 and 3 to enable testing on how individuals respond to opioids, further consent will be obtained for these samples. Data on benefits, side effects, and medical care will be collected during comprehensive weekly visits. Participants will also fill out a simple diary twice daily for weeks one to three of the study, and for one day each week during an optional 6 month extension stage. The outcome of this study may enable better management of symptoms and activity in people COPD with medicines that are shown to be effective and safe.
This cross sectional study will be carried out on 30 subjects who will be recruited from the outpatient clinic of Chest Department, Tanta University Hospital. They will be classified into 3 groups: Group I: It will include 10 healthy volunteer subjects. Group II: It will include 10 asthmatic patients. Group III: It will include 10 COPD patients. miR-7, miR-20a, miR-21, miR-22, miR-145 and miR-155 will be measured in serum samples from all subjects
The purpose of this study is to determine the minimal important difference (MID) for the 1-minute-sit-to-stand-test (STST) with an anchor-based method.
Pulmonary rehabilitation (PR) is an exercise program tailored for patients with chronic lung disease that is a core part of the management of patients with Chronic Obstructive Pulmonary Disease (COPD). Many COPD patients develop low oxygen levels (desaturation) during exercise and this is often discovered when they are being evaluated for PR. Current practice is to administer oxygen to COPD patients with exercise-induced desaturation, but this is based on very limited evidence. This limited evidence relates to a short-term increase in exercise capacity and it is not known if this translates into longer term increases in activity or whether providing these patients with oxygen improves outcomes after PR. In addition it is not known if patients given ambulatory oxygen continue to use it after completing PR. Evidence for a beneficial effect of oxygen would provide a more solid evidence base for its use. Conversely demonstration of no effect would allow reassessment of the use of oxygen and whether the costs are justified. Therefore the aims of this study are to assess the effects of oxygen on outcomes from PR and assess the usage of ambulatory oxygen following completion of PR.
