Filter by:The purpose of this study is to determine if ramelteon has respiratory depressant effects in subjects with moderate to severe chronic obstructive pulmonary disease.
The aim of the study is to compare the efficacy of roflumilast on pulmonary function and symptomatic parameters in patients with chronic obstructive pulmonary disease (COPD) during concomitant administration of salmeterol. The study duration will last up to 28 weeks. The study will provide further data on safety and tolerability of roflumilast.
Treatment with systemic corticosteroids for acute exacerbations of COPD results in the improvement of clinical outcomes. The optimal route of administration has not been rigorously studied in COPD. Upon hospitalization, corticosteroids are administered intravenously in many hospitals. Oral administration is more convenient, though, because there is no need for intravenous access, less personnel is required for starting and monitoring therapy, and material costs are smaller. The investigators hypothesized that oral administration is not inferior to intravenous administration of prednisolone in the treatment of patients hospitalized for an acute exacerbation of COPD.
The Comprehensive Lung Center (CLC) at the University of Pittsburgh Medical Center (UPMC Health System) provides patients with any type of breathing or lung disorder a full range of diagnostic and therapeutic services. The Emphysema/COPD Research Center (ECRC) is a specialty clinic, within this center, that attempts to advance the understanding of emphysema and to evaluate new therapies for patients with emphysema. The Emphysema Research Registry will enable pulmonary research physicians to: 1) gather information and create a research registry of people who have been diagnosed with emphysema; 2) utilize this research registry with the purpose of conducting research that attempts to advance the understanding of emphysema and to evaluate new therapies; and, 3) use the research registry to identify potential candidates for future research programs. These aims will be achieved by the collection of DNA (genetic material)for analysis and storage in addition to pulmonary function tests and other medical information.
This will be a prospective randomized double-blinded parallel group clinical trial evaluating the short-term effects of theophylline therapy on exercise duration and lung function in patients with chronic obstructive pulmonary disease already receiving both tiotropium and a long-acting beta-agonist (salmeterol or formoterol).
Cigarette smoking causes an increase in inflammation in the lungs. In about 20% of smokers this inflammation leads to damage in lungs including making holes in the lung tissue. This damage can not be repaired and these people find it very difficult to breathe. One of the problems with this disease called chronic obstructive pulmonary disease, or COPD for short, is that by the time patients visit their doctor with symptoms, the damage has already been done. At the moment, there is no way to predict which smokers will go on to develop COPD. The aim of this research is to look at smokers who breathe normally and use an imaging technique called a CT scan, to look at their lungs in more detail. Some of these people will have spots on their scan which may be caused by inflammation. We want to look at the cells at these spots to see if they make more proteins and enzymes that cause lung damage when compared to people that do not have these spots. We would then be able to predict which smokers are likely to develop COPD and treat them early before they have damaged their lungs.
Patients with chronic obstructive pulmonary disease (COPD) that have frequent chest infections are the patients most likely to become worse over time. Why these people are more susceptible to chest infections is not known. One reason might be that the white cells in their lungs called macrophages do not work properly. Normally, these cells remove all the debris inhaled into the lung. This can also include bacteria. In patients with COPD, these macrophages are not able to remove these particles. The research question addresses why this happens
The aim of the study is to compare the effect of roflumilast on exacerbation rate and pulmonary function in patients with chronic obstructive pulmonary disease (COPD). Roflumilast will be administered orally once daily in the morning at one dose level. The study duration will be up to 56 weeks. The study will provide further data on safety and tolerability of roflumilast. For additional information (for US patients only) see www.COPDSTUDY.net or dial 866-788-2673 (toll free).

The aim of the study is to observe the ventilatory and cardiac function (included the pulmonary arterial pressure) during an intermittent work exercise test with high density work load.
