Filter by:This study is to assess the effects with two different inhaled respiratory medications with regards to improvement of lung function, symptoms and morning activities.
Obstructive lung disease is usually a differential diagnostic consideration when a patient presents with breathlessness or cough. Spirometry is the key diagnostic test used to confirm airflow obstruction particularly in the primary care setting. Airflow obstruction that completely resolves after administration of a bronchodilator, by definition, excludes a diagnosis of COPD. Evaluation of obstructive lung disease must include pulmonary function testing; bronchoreversibility testing is an adjunct in differentiating between asthma and COPD. Bronchoreversibility cannot serve as an absolute diagnostic criterion for separating asthma from COPD. Vibration response imaging (VRI) technology provides a simple, radiation-free method to image the lungs, by visualizing vibration energy (lung sounds) emitted during respiration cycle. In this study, regional quantitative and qualitative information on vibration response is compared with spirometry in assessing lungs function of COPD and Asthma patients.
This observational non-interventional study is designed to demonstrate the improvement of physical function in COPD patients with exercise-induced dyspnoea on treatment with Spiriva (tiotropium 18 µg capsules) and allows adverse events to be recorded and evaluated.
Cigarette smoking is the main risk factor for chronic obstructive pulmonary disease (COPD). The cells lining the lung airways (epithelium) and the cells on the surface of the epithelium (alveolar macrophages) of healthy smokers develop characteristic gene expression changes that are different from that of nonsmokers. These gene expression changes include up- and down-regulation of genes in functional categories known to be relevant to the development of COPD. Administration of anti-inflammatory medications (inhaled steroids) in combination with long acting medications that open the airways (bronchodilators), are known to decrease the rate of acute exacerbations and improve the quality of life of individuals with COPD; however, the mechanisms underlying these beneficial effects of are poorly understood. This study will assess the effect of traditional therapy for COPD (inhaled corticosteroids, an anti-inflammatory medication, plus a bronchodilator, a medication that helps open the airways) on smoking-induced gene changes in airway epithelium and alveolar macrophages. Volunteer subjects will be evaluated by bronchoscopy to sample lung cells at 0, 7 and 14 days, with the therapy given at day 1 through day 7. The bronchoscopy aspects of this study will be covered by approved Weill-Cornell IRB protocol # 0005004439 (see below.) To participate in this protocol, the research subject will first be enrolled in Weill-IRB protocol #0005004439 entitled "Evaluation of the Lungs of Normal (Smokers, Ex-smokers, Non-Smokers) Individuals with Segmental Bronchopulmonary Lung Lavage, Bronchial Brushing, and Bronchial Wall Biopsy", fulfilling the inclusion/exclusion criteria of that protocol. They will be invited to participate in this protocol only if they meet the additional inclusion/exclusion criteria of this protocol.
This study will assess the safety and tolerability of QAT370 compared to tiotropium in patients with COPD.
Short course of steroids in COPD exacerbation improves FEV1 and decreases the relapse rate. However, some concerns remain about using systemic steroids for all patients with acute exacerbation. Their short-term advantages may be outweighed by the occurrence of adverse side effects such as hyperglycemia, which is difficult to manage on an outpatient basis. In this context, the possibility of treating patients with COPD exacerbation with inhaled steroids having less systemic adverse effects is interesting. The objectives are to compare relapse rate, lung function, the severity of dyspnea and, systemic and sputum inflammatory markers in outpatients with acute COPD exacerbations treated with fluticasone/salmeterol (Advair®) or oral prednisone for 10 days. The hypothesis is that Advair® is as effective as prednisone in treatment of outpatients with COPD exacerbation. The primary endpoint is to determine if the relapse rate at one month is equivalent for both treatments. The secondary endpoints are to compare lung function and dyspnea score and, systemic and sputum inflammatory markers modulation after 10 days of both treatments. We will recruit 30 outpatients in each group from our COPD clinic. Patients will receive prednisone (40mg/day) with placebo diskus or Advair® 50/500ug 2 inhalations bid (twice the regular dose) with placebo pills for 10 days. All patients will receive antibiotics and short-acting bronchodilators as needed. We expect to demonstrate that the improvement of lung function, dyspnea, inflammatory markers and relapse rate are equivalent in both treatments suggesting that Advair® could be a good alternative to prednisone for patients with steroid-induced hyperglycemia.
This study investigated the effect of exercise and high-dose salbutamol on the maximum heart rate in patients with chronic obstructive pulmonary disease (COPD) receiving therapeutic doses of indacaterol, salmeterol and placebo.
This study was designed to test the following hypothesis: The acute changes in exercise tolerance during the endurance shuttle walk will be greater with salmeterol compared to placebo in patients with chronic obstructive pulmonary disease.
The purpose of this study is to determine which COPD patients have GERD and if COPD patients with GERD treated with high dose lansoprazole for 1 year decreases the frequency of COPD exacerbations compared to the previous year without treatment.
The purpose of this study is to evaluate the safety and efficacy of the Biologic Lung Volume Reduction System (BLVR) for patients with advanced emphysema refractory to medical therapy.
