Filter by:Targeted Lung Denervation (TLD) Therapy will be a safe method to ablate the airway nerve trunks that travel parallel to and outside of the main bronchi and into the lungs to achieve targeted lung denervation and potentially improve breathing and quality of life for patients suffering from COPD. Use of the IPS System will be technically feasible in accessing the target treatment location and delivering RF energy to the target treatment location.
The aim of this study was to assess the effectiveness for small airway inflammation of 4 weeks lysozyme administration in Chronic Obstructive Pulmonary Disease (COPD) and/or asthma.
Pulmonary rehabilitation has been established as an evidence-based and recommended therapy in patients with chronic obstructive pulmonary disease (COPD). The aim of our study is to show a potential change in muscle fibre composition and in the amount of capillaries in quadriceps muscle from pre tob post 3-week rehabilitation. Pulmonary rehabilitation includes standardised exercise training, e.g. cycling and strength training for major muscle groups.
The study serves to determine whether the treatment of patients with stable, symptomatic Chronic Obstructive Pulmonary Disease (COPD) with the investigational drug NVA237 is efficient and safe. The efficacy and safety of the drug will be tested against a placebo treatment. The primary criterion to assess efficacy will be the difference between the serial lung function measurements of patients who have been treated for 12 weeks with NVA237 versus those that have received placebo treatment for 12 weeks. A serial lung function measurement (FEV1 testing) will be conducted and the "area under the curve" will be the measure for the ability to breathe.
The Oxymizer pendant® is a special oxygen cannula that can be used to supply high flow long term oxygen therapy. It is compatible with a wide variety of oxygen sources. In a reservoir, the Oxymizer® stores pure oxygen so that the concentration of inhaled oxygen is increased. The aim of this study is to investigate the potential benefit of the Oxymizer® with regard to the blood oxygenation during exercise testing. Given that the "endurance time" is very sensitive for little changes in exercise capacity, this test will be used to show the difference between the Oxymizer® and a conventional nasal cannula regarding exercise duration at 70% of peak Watt and oxygenation. The tests will be accompanied by blood gas analysis, partial pressure of carbon dioxide and heart rate.
The aim of this study was to evaluate kallikreins and its substrate, CCN, in COPD patients. Kallikreins are a subgroup of serine proteases, enzymes which are able to cleave peptide bonds in proteins. Kallicrein profile is unkonwn in COPD. The investigators will assess Kallikrein 1 to 15 and CCN 1 to 6 in sputum of patients. Three groups of patients will be included: Healthy smoker subjects, stable COPD patients and COPD patients with acute exacerbation. Kallicrein levels in sputum will be compared in these groups.
The purpose of the investigation is to confirm the safety and efficacy in long-term use of Symbicort Turbuhaler in patients with Chronic obstructive pulmonary disease (COPD) under the post-marketing actual use.
This study will assess the efficacy, safety and tolerability of indacaterol maleate/glycopyrronium bromide in patients with moderate to severe airflow limitation.
Patients with moderate chronic obstructive pulmonary disease (COPD) typically have reduced exercise capacity. This is because their lungs are damaged and because of increased work of breathing. In some patients, exercise capacity is reduced to such a level that even simple activities of daily living, such as washing and dressing, may impose a challenge. Recent findings in healthy young people suggest that increasing the amount of nitrate in our diet in the form of beetroot juice can improve the ability to exercise. Studies involving cycling have shown that less oxygen is needed to perform the same level of exercise after taking more nitrate in the diet. Nitrate (found in abundance in beetroot) is known to be converted in the body to nitric oxide (NO), a substance which increases blood flow and may affect the energy-producing mechanisms inside muscle cells. A recent exciting finding is that such dietary nitrate supplementation appears to reduce the amount of oxygen needed to complete moderate intensity exercise (walking) in healthy individuals. It is the purpose of this study to see if such effects could be seen in COPD patients. If this is indeed the case, then it may suggest that a period of dietary supplementation of a relatively cheap, widely available, and natural food product may improve the ability of patients to undergo everyday tasks and ultimately improve their quality of life. To help investigators understand the effects of dietary nitrate supplementation on the ability to exercise in COPD patients, the investigators will recruit 15 people with mild to moderate disease. They will complete a series of undemanding exercise tests on three separate occasions. On one occasion they will have had a course of nitrate rich beetroot juice leading up to the tests, and on the other occasion they will have had a course of beetroot juice with the nitrate removed. The investigators will monitor blood pressure, levels of nitrate and nitrite in the blood, oxygen uptake and functional capacity during the tests which will allow us to assess any effects that may have occurred as a result of increased nitrate intake.
An open label study in 40-60 subjects with diagnosed lung airway disease and in 10-20 normal controls. Each subject will receive PFP as a contrast agent to visualize the airway and alveolar spaces in their lungs using magnetic resonance imaging of inert gas/oxygen mixtures.
