Active clinical trials for "Lung Diseases"

This study is designed to investigate the effect of home mechanical ventilation (HMV) in patients with severe chronic obstructive pulmonary disease (COPD). The purpose of the trial is to test the hypothesis that HMV and longterm oxygen therapy (LTOT) increases admission free survival compared with LTOT alone. More specifically, compared with LTOT, HMV and LTOT reduces hospital re-admission in COPD patients who remain persistently hypercapnic following an acute exacerbation requiring non-invasive ventilation (NIV).

Chronic obstructive pulmonary disease (COPD) is currently the fourth leading cause of death in the United States. Unlike the other leading causes of death, no medical therapies currently available improve the course of disease or affect survival in COPD. Recent investigations suggest that endothelial dysfunction and chronic inflammation is fundamental to COPD. Fish oil intake improves endothelial dysfunction and lowers levels of inflammatory intermediaries which may be important in the development of COPD. The Chronic Obstructive Pulmonary Disease Fish Oil (COD-Fish) Pilot Trial will enroll 40-45 participants with COPD. These participants will be randomized to receive omega-3 polyunsaturated fatty acid supplementation (PUFA) or placebo (containing corn oil). All participants will perform a number of noninvasive tests (including flow-mediated dilation (FMD) and pulmonary function testing) at study entry as well as every two months for a total of six months. Thirty participants who agree to it will undergo a separate procedure to collect cells from inside a forearm vein for analysis to be compared to 30 controls. The main purpose of this trial is to examine the effect of PUFA on endothelial function as measured by change in FMD in patients with COPD. We hypothesize that in subjects with COPD, treatment with PUFA will increase FMD.

The purpose of this study was to evaluate the efficacy, safety, and tolerability of single doses of trospium inhalation powder (TrIP) administered to subjects with chronic obstructive pulmonary disease (COPD).

The primary objective of the trial is to determine the effect of BI 17444Cl on the lung function over a 24-hour period, when it is inhaled using the Respimat inhaler in patients with chronic obstructive pulmonary disease. In the trial four treatments of each 3 weeks of duration are included: 2 dosages in a once daily administration and 2 dosages for administration twice daily.

The purpose of the study is to assess the safety and the effect of treatment by PulseHaler™ on patients with COPD, as measured by the change from baseline in full pulmonary functions, oxygen saturation, exercise tolerance and health related quality of life; and to assess the ease of use of PulseHaler™ by the patients.

The purpose of the study is to determine the efficacy and safety of the combination of ADVAIR DISKUS® 250/50mcg (FLUTICASONE PROPIONATE/SALMETEROL COMBINATION PRODUCT) plus SPIRIVA® HANDIHALER® inhaler 18mcg (TIOTROPIUM) compared to SPIRIVA® HANDIHALER® inhaler 18mcg (TIOTROPIUM) in patients with COPD.

Chronic obstructive pulmonary disease (COPD) is characterized by increased oxidative stress which aggravates airway and systemic inflammation. Previous studies suggested that dietary factors such as ample consumption of antioxidants might have beneficial effects in lung function in COPD patients. The investigators' primary aim is therefore to investigate prospectively whether a nutritional intervention consisted of diet rich in antioxidants such as fresh fruits and vegetables, would significantly affect lung function decline in COPD patients compared to a free diet. Methods: This is a 3-year prospective study, incorporating a run-in period of six months and outpatient clinic visits, scheduled every 6 months. Consecutive sampling was used to recruit 120 patients with COPD. At baseline and at each visit all patients were evaluated for respiratory symptoms, dietary habits, medication used and pulmonary function. Patients will be randomized either to a diet based on increased consumption of foods containing antioxidants (fresh fruits and vegetables), intervention group (IG) or, to a free diet, control group (CG). The investigators hypothesize that the results from the study will suggest that a diet rich in antioxidants may be associated with improvement in lung function in COPD patients. In this respect dietary interventions should be considered in the management of COPD.

This study was designed to test the following hypothesis: The benefit of electrostimulation training will be greater than sham stimulation training in term of muscle strength and mass (muscle hypertrophy), exercise tolerance, reduction of ventilation during exercise and quality of life in COPD patients

The purpose of this randomized controlled trial is to evaluate the hypothesis that the 'written' action plan, a self-management tool developed by the project group, enhances early detection and prompt action measures and consequently isbeneficial in exacerbation outcome (i.e., health status recovery time).

The purpose of the study is to evaluate the safety of administering repeated doses of CTX-100 (formerly ETX-100) to subjects with smoking-related chronic obstructive pulmonary disease.
