Active clinical trials for "Lung Diseases, Obstructive"

The purpose of this study is to determine whether the alveolar macrophages (AMø) of patients with chronic obstructive pulmonary disease (COPD ) show abnormal responsiveness to bacterial and viral products, relative to smokers with normal pulmonary function. Participation in this study will be offered to patients already scheduled to undergo a bronchoscopy for clinical indications.

This study group forms the normal subject control group in an experiment designed to determine whether the alveolar macrophages (AMø) of patients with chronic obstructive pulmonary disease (COPD) show abnormal responsiveness to bacterial and viral products. Specifically, the study will determine the dose-response characteristics of AMø for production of interleukin (IL)-6, IL-18, and IL-23 (pro-inflammatory cytokines) on stimulation by purified lipopolysaccharide, a synthetic lipopeptide (PAM3-Cys), or poly I:C. These stimuli mimic the response to Gram-negative bacteria, Gram-positive bacteria, and RNA viruses, respectively. Results of the AMø from these healthy volunteers will be compared with AMø of COPD patients and smokers (or ex-smokers) with normal pulmonary function; those samples are being obtained during clinically indicated bronchoscopies under a separate consent form.

The purpose of this study is to evaluate with sufficient precision and according to gender the determining independent factors of quality of life related to respiratory status of patient with moderate to severe COPD.

The study aim is to verify the association between the changes in markers of disease and patient´s prognosis in chronic obstructive pulmonary disease.

Under daily routine conditions and without any intervention by the sponsor regarding the selection of subjects, diagnostic procedures, therapeutic decisions (medicinal and non- medicinal therapy, dose, duration, etc.), routine assessments, the participating physicians (i.e. pneumologists and internists) are asked to document relevant data related to the budesonide/formoterole therapy in patients with COPD.

This study aimed to assess airway inflammation in patients during the course of acute exacerbations of chronic obstructive pulmonary disease (AECOPD) by serial analyses of their exhaled breath condensates (EBC).

To conduct a longitudinal study of the relationship between the rate of decline of pulmonary function and measurements of cortisol concentration and excretion in a sample of middle-aged and older men and their wives. The study tested the hypothesis that persons whose plasma cortisol concentrations were relatively low, albeit within the normal range, were predisposed to excessively rapid deterioration of pulmonary function during aging.

To provide information necessary for the development of standards for peak expiratory flow (PEF) test performance in populations studies.

In the literature, there are a limited number of studies evaluating postural awareness, cognitive status, respiratory muscle strength and endurance, functional capacity, and pain in people with obstructive pulmonary disease, and comparing these parameters with each other and with healthy subjects, and most of the studies are on chronic obstructive pulmonary disease patients. There we will evaluate these parameters in different obstructive lung diseases and compare the findings of healthy individuals.

The balance, gait and pain in Chronic Obstructive Pulmonary Disease (COPD) study will aim to investigate the link between balance and gait impairment, and high rates of pain in people with COPD. This cross-sectional observational study will compare balance and gait outcomes for people with COPD who have pain, to those who are pain free.
