This is a randomized, open-label, parallel group, multicenter, outpatient study in COPD subjects who are discharged from the hospital due to a COPD exacerbation. Subjects who meet the eligibility criteria will be randomized to 1 of 2 treatments: arformoterol tartrate inhalation solution (BROVANA) 15 mcg twice daily (BID) or tiotropium bromide (SPIRIVA) 18 mcg once daily (QD), each given for 90 days.
Preliminary data show that in COPD patients, HFT substantially decreases ventilatory demand during sleep. The central hypothesis of this proposal is that lowering ventilatory demand using nasal high-flow therapy during sleep will elevate lung function, reduce dyspnea on exertion and improve quality of life. Thus, this proposal aims will determine the effects HFT over time on 1) lung function; 2) dyspnea on exertion; and 3) quality of life.
The investigators' hypothesis is that pretreating patients with COPD with inhaled treprostinil prior to pulmonary rehabilitation sessions will result in improved exercise tolerance during sessions. This in turn will lead to an increased response to pulmonary rehabilitation, resulting in improved exercise tolerance and quality of life.
The purpose of this study is: 1.- to assess the safety and tolerability of autologous adipose derived stem cells (aADSC) administered intravenously in patients with chronic obstructive pulmonary disease, and 2.- to assess if this therapy results in less decrease of lung function parameters (FEV1, FEV1/FVC and 6 min walking distance) compared with a control baseline of 6 weeks. Patients will be followed up for 12 months after the therapy.
This project (funded by the IWT-TBM program) will organize a randomized placebo-controlled multicenter intervention trial in 500 COPD patients to study the effectiveness and safety of azithromycin therapy in the acute setting of COPD exacerbations requiring hospital admission. Although long-term use of azithromycin is proven effective to prevent exacerbations, inherent risks outweigh the benefits. By reducing the dose and duration of the azithromycin treatment and by restricting the treatment to acute periods with highest risk for treatment failure, benefits may counterbalance potential side effects, which may result in a new treatment strategy for these acute events. The present study is designed by the services of respiratory medicine of the Leuven and Ghent University hospitals but will run in total in 17 different large hospitals in Belgium, of which 12 are located in Flanders.
This trial hopes to demonstrate the effect of 4 weeks of outpatient exercise rehabilitation on COPD patients. In particular the effect on: - the amount of daily physical activity - Quality of life - The 6-minute walk distance - Time to exacerbation and compare it to the effect of 4 weeks of outpatients rehabilitation with Noninvasive Ventilation as an adjunct therapy.
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.
Cigarette smoking is the major cause of chronic obstructive pulmonary disease (COPD), the 4th cause of mortality in the US. Central to COPD pathogenesis is "ciliopathy", dysfunction of the airway ciliated cells that mediate transport of mucus to remove inhaled pathogens. The focus of this study is to carry out metabolic profiling of banked biologic samples and assess the hypothesis that COPD is associated with a unique metabolome in serum and lung epithelial lining fluid, and that subsets of the COPD metabolome are linked to the ciliopathy of COPD.
