Active clinical trials for "Lung Diseases"

The purpose of this study is to improve anti-inflammatory medication adherence and asthma outcomes by using reports of peak flow monitoring to prompt communication between patients and their doctors.

Human and animal studies have shown that inhaled corticosteroids (ICS) decrease airway blood flow . This effect is immediate (within 30 minutes), transient (lasting 90 minutes), and in animal studies independent of gene expression. In COPD patients, decrease in bronchial blood flow may also decrease mucosal edema, airway resistance and improve small airway function. If such an effect exists, then we should be able to measure improvements in airway conductance and reduce lung hyperinflation, which would have salutary effects on dyspnea and exercise endurance. To our knowledge, no study has examined the immediate effect of ICS on small airway function in COPD. The purpose of this study is to examine the effects of nebulized Pulmicort on small airway function (spirometry, plethysmographic lung volumes, airways resistance, closing volume, partial flow-volume loop analysis) and exercise endurance in patients with moderate to severe COPD. HYPOTHESIS Nebulized ICS will immediately improve airway function compared with placebo (nebulized saline). Enhanced lung emptying and reduced operating lung volumes during rest and exercise following ICS therapy will translate acutely into clinically important reductions in exertional dyspnea and improvements in exercise endurance.

In animal models, sodium pyruvate has been shown to be an effective anti-inflammatory agent, and in human studies sodium pyruvate has been shown to be a bronchodilating agent. Subjects with COPD are known to have inflammation in the lung, and often have bronchoconstriction. As such, these subjects typically are on multiple therapies, including steroid therapy. This trial will study the effect of inhaled sodium pyruvate on inflammation and lung function in COPD subjects over a six week period.

The study was designed to determine whether tiotropium inhalation capsules, compared to placebo, enhances the improvement in exercise tolerance seen in patients with chronic obstructive pulmonary disease (COPD) who participate in pulmonary rehabilitation. In addition, assessments of the effect of tiotropium on dyspnea and quality of life following pulmonary rehabilitation were taken.

To evaluate changes in PaO2 following inhalation of Tiotropium by HandiHaler compared to Salmeterol MDI in patients with moderate to severe COPD.

The objective of the study was to evaluate the degree of improvement in lung function in patients with chronic obstructive pulmonary disease (COPD) after treatment with tiotropium inhalation capsules compared to salmeterol inhalation aerosol .

The primary objective of this study is to investigate the effect of tiotropium vs. placebo on trough FEV1 and FEV1 2 hours post inhalation after 12 weeks of treatment. For both endpoints changes from baseline will be analysed. Three strata of patients will be included (severe COPD, i.e. <35% of predicted FEV1, moderate COPD, i.e. 35% - <50% of predicted FEV1, mild COPD, i.e. 50% - 70% of predicted FEV1, according to American Thoracic Society [ATS] criteria). The study is conducted in order to find out for which endpoint tiotropium is different from placebo in which stratum.

To evaluate current and novel therapies and management strategies for children with asthma. The emphasis is on clinical trials that help identify optimal therapy for children with different asthma phenotypes, genotypes, and ethnic backgrounds and children at different developmental stages.

The purpose of this study is to investigate the effect of a 9-month treatment of tiotropium (SPIRIVA®) 18 mcg once daily on Health Related Quality of Life and lung function in patients with a Chronic Obstructive Pulmonary Disease.

To evaluate acute effect of single dose of ipratropium (Atrovent) or fenoterol (Berotec) in comparison to placebo when given to COPD patients on pharmacodynamic steady state of tiotropium (Spiriva)
