Lung cancer, largely the result of cigarette smoking, is the leading cause of cancer death in the United States, killing over 160,000 people in 2010, more than breast, colorectal, and prostate cancer combined. Since only 10% of heavy smokers develop lung cancer and 20% of lung cancers develop in nonsmokers, it is thought that genetic predisposition plays an important role. This study proposes to examine the genetic correlation between nasal and bronchial epithelium and to identify a patient's risk for lung cancer earlier.
Early changes associated with the development of smoking-induced diseases, e.g., COPD and lung cancer (the two commonest causes of death in U.S.) are often characterized by abnormal airway epithelial differentiation. Airway basal cells (BC) are stem/progenitor cells necessary for generation of differentiated airway epithelium. Based on our preliminary observations that epidermal growth factor receptor, known to regulate airway epithelial differentiation, is enriched in BC and its ligand EGF is induced by smoking, we hypothesized that smoking-induced EGF alters the ability of BC to form normally differentiated airway epithelium. To test this, airway BC will be purified using a cell-culture method established in our laboratory and responses to EGF will be analyzed using genome-wide microarrays and an in vitro air-liquid interface model of airway epithelial differentiation.
People with chronic obstructive pulmonary disease (COPD) are very sedentary and efforts to establish an active lifestyle are challenging because of periodic acute exacerbations of COPD that interrupt physical activity patterns and contribute to further decline in physical activity. The purpose of this preliminary research is to learn more about the experience of acute exacerbations of COPD (AECOPD) from the perspective of the patient and his/her family and to learn how AECOPDs affect physical activity.
This is a randomized, double-blind, cross-over, vehicle-controlled study to determine whether GS-5737 in 2.8% saline accelerates mucociliary clearance (MCC) in healthy subjects, compared to vehicle of 2.8% saline alone.
This is a report of a protocol developed to improve asthma and COPD care in a primary care setting. The study was approved by an Ethics Committee and support by the Canadian Thoracic Society through an unrestrictive grant from GlaxoSmithKline. However, the study could not be done and the investigators report why, discussing the difficulties to perform such study. This information should be very useful to investigators planning this sort of study.
The purpose of this research study is to determine whether exhaled nitric oxide (FeNO) goes up during an acute exacerbation of Chronic Obstructive Pulmonary Disease (AECOPD) and whether the level of exhaled nitric oxide returns to normal in the weeks after an exacerbation.
To investigate whether Budesonide/Formoterol (Symbicort ®) therapy can improve heart function at rest by decreasing lung hyperinflation in patients with COPD (Chronic Obstructive Pulmonary Disease).
The purpose of this study is to investigate how budesonide/formoterol fumarate dihydrate (Symbicort ©) affects dynamic hyperinflation in patients with obstructive disease using Optoelectronic Plethysmography (OEP). This study is unique as it will be the first randomized, doubleblind, crossover study with a placebo inhaler and budesonide/formoterol fumarate dihydrate as the intervention which will evaluate the effects on ventilatory mechanics through the use of OEP. The investigators plan to demonstrate that budesonide/formoterol fumarate dihydrate impacts dynamic hyperinflation which can be detected with OEP, and that budesonide/formoterol fumarate dihydrate may have an effect in the short term on exercise capacity during a constant load exercise test. The changes in ventilatory mechanics measured after budesonide/formoterol fumarate dihydrate by OEP will provide a unique evaluation of budesonide/formoterol fumarate dihydrate in a controlled setting also demonstrating the utility of OEP in evaluating of the effects of a medical treatment on hyperinflation in individuals with chronic obstructive lung disease (COPD). 1. Primary Objective/Hypothesis: Our objective is to measure baseline, post treatment and post exercise spirometry and evaluate exercise dynamic hyperinflation before and after treatment using OEP. The investigators hypothesize that budesonide/formoterol fumarate dihydrate will decrease dynamic hyperinflation as measured by OEP. 2. Primary Endpoint: Our primary endpoint is the change in dynamic hyperinflation, specifically end expiratory volumes, dynamic lung volumes and diaphragmatic paradoxical breathing as measured by OEP. 3. Secondary Objective: Our secondary objective is to evaluate duration of steady state exercise and exercise capacity before and after treatment. Our secondary hypothesis is that decreases in dynamic hyperinflation during exercise will lead to improvements in dyspnea with exercise, and allow for increases in exercise capacity. 4. Secondary endpoint: Exercise time, change in Borg scale at rest vs. Borg scale at steady state vs. Borg at end exercise.
This study in Chronic Obstructive Pulmonary Disease (COPD) patients will investigate the bronchodilatory effect of AZD8683. AZD8683 will be tested versus placebo and an active comparator.
