The purpose of this study is to compare Symbicort in a pressurized metered-dose inhaler (pMDI) with formoterol and placebo in the long-term maintenance treatment of patients with chronic obstructive pulmonary disease (COPD).
The purpose of this study is to compare a combination asthma drug (Symbicort) with its two components, budesonide and formoterol, taken individually or in combination, and with placebo in the long-term maintenance treatment of patients with chronic obstructive pulmonary disease (COPD)
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 1. Nebulized ICS will immediately improve airway function compared with placebo (nebulized saline). 2. 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 people with mild COPD, the ability to exhale air from the lungs is partly limited because of narrowing and collapse of the airways. This results in the trapping of air within the lungs and over-distention of the lungs and chest (lung hyperinflation). Breathing at high lung volumes (hyperinflation) is an important cause of breathing discomfort (dyspnea) in people with COPD. Bronchodilators help to relax muscles in the airways or breathing tubes. Bronchodilators are often prescribed if a cough occurs with airway narrowing as this medication can reduce coughing, wheezing and shortness of breath. Bronchodilators can be taken orally, through injection or through inhalation and begin to act almost immediately but with the effect only lasting 4-6 hours. The main purpose of this study is to examine the effects of inhaled bronchodilators on breathing discomfort and exercise endurance in patients with mild COPD.
The study will evaluate the efficacy and safety of basiliximab Vs placebo as induction therapy combined with standard triple immunosuppression therapy, in the prevention of acute rejection episodes and prevention of Bronchiolitis Obliterans Syndrome.
Does an oral selenium supplement increase blood levels of antioxidants in patients with established, smoking-related lung disease? Members of our study group recently discovered that elevated levels of the anti-oxidant GPx-1 may be protective against heart disease. We are studying whether selenium supplementation will improve GPx-1 levels.
