Filter by:The primary objective of this study is to determine if quantitative Dynamic contrast-enhanced magnetic resonance (DCE MR) perfusion imaging accurately quantifies right and left pulmonary artery blood flow as compared with phase contrast flow velocity mapping (PC), the current gold standard of flow volume measurements.
The primary purpose of the study is to evaluate the safety and tolerability of fluticasone furoate/GW642444 inhalation powder when administered once-daily for 52 weeks in Japanese patients with COPD.
The main objective is to evaluate the bronchodilatory efficacy, safety and pharmacokinetic profiles of A006 (Albuterol Dry Powder Inhaler (DPI)), in comparison with those of an active control, Proventil-HFA (Albuterol Metered Dose Inhaler (MDI)), and a Placebo DPI in escalating and cumulative-doses up to 1440 mcg, eight (8) times of the proposed clinical dose.
This is a 26 week randomized controlled study. The study consists of, in order, an enrollment visit, followed by clinic visits at 2 weeks, 14 weeks and at 26 weeks. There will also be telephonic assessments at 8 weeks and 20 weeks. Clinic visits will involve comprehensive assessments of the patients lung condition, including post-bronchodilator spirometry, Shuttle walk distance, BODE index, health status (SGRQ) and symptoms (CCQ). Sputum and serum samples will also be collected at these visits for microbiological and inflammation analysis. Sputum will be obtained with the Lung Flute as an induction device and Pulse Oximetry will be assessed prior to and after use of the Lung Flute. Clinic and telephonic visits will collect information regarding compliance with the use of the Lung Flute, adverse events and exacerbation history.
National Institute for Clinical Excellence (NICE) guidelines recommend high dose inhaled steroids for patients with moderate to severe Chronic Obstructive Pulmonary Disease (COPD, a common chronic disease related to smoking) who are having two or more exacerbations requiring treatment with antibiotics or oral steroids in a 12 month period. The preparations licensed for this indication commercially available are Symbicort® and Seretide®. High dose inhaled steroids (contained in both) can cause suppression of the adrenal glands. The investigators want to assess adrenal suppression caused by the two preparations and compare. The results could guide investigators in prescribing these preparations.
This study is being conducted to find out if the use of inhaled corticosteroids has an affect on upper airway collapsibility and sleep apnea risk. An inhaled corticosteroid is a common asthma controller medication like Flovent. Sleep apnea is w hen someone stops breathing for a short period of time during sleep. For some reason, people with asthma have more sleep apnea and upper airway collapsibility (weakness) than the general population. There are many possible reasons for this and one might be related to the use of inhaled corticosteroids. The overall hypothesis of this study is to determine whether inhaled fluticasone propionate (FP) increases UAW collapsibility and to assess tongue (genioglossus muscle) dysfunction as a potential underlying mechanism.
This study is designed to provide clinical data regarding safety and clinical effectiveness of the ActiSight Needle Guidance System in assisting radiologically guided percutaneous needle biopsy or aspiration of pulmonary lesions, which is a common procedure.
The purpose of this study is to assess the procedural and post-procedural safety and efficacy of AeriSeal therapy at up to 4 subsegments during a single treatment session in patients with GOLD Stage III/IV homogeneous or heterogeneous emphysema.
Non-invasive ventilation (NIV) in severe hypercapnic Chronic Obstructive Pulmonary Diseases (COPD) may be associated - during sleep - with recurrent episodes of patient ventilatory asynchrony, which in turn may affect quality of sleep, efficacy of ventilation and comfort of nocturnal NIV.Polysomnography (PSG) under NIV is necessary to detect these events. Adjusting ventilator settings according to respiratory events detected by PSG with NIV may improve quality of sleep, efficacy of ventilation and comfort of nocturnal NIV.
The investigators have taken part in the development of simple muscle function tests and studied physical training and energy turnover in patients with chronic obstructive pulmonary disease, COPD. The investigators have found that muscle wasting in COPD is related to poor prognosis and that physical training might lead to improved, less energy-demanding muscle function. Elderly subjects also suffer from muscle wasting that leads to frailty, poor autonomy and, secondarily, fractures. In the planned study the investigators will validate simple muscle function tests (hand grip strength, heel rise test, voluntary quadriceps muscle strength, 30 m walking test and balance tests) in both groups by relating them to an involuntary, magnet stimulated, test of quadriceps force, HRQL, tests of body composition (impedance, DXA) and recordings of physical activity. The relation between food intake, systemic inflammation, muscle mass and function will be analysed. The study has been ethically approved and started in COPD patients and will be expanded to a representative sample of elderly. Simple, evaluated muscle function tests applied in primary care may be used for early detection of muscle dysfunction in COPD patients and elderly so that early intervention against impaired muscle function can be started. Analyses of food intake and of inflammatory markers might identify factors of special importance for muscle dysfunction, which eventually might lead to improved dietary therapy and pharmacological interventions.
