Active clinical trials for "Lung Diseases, Obstructive"

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.

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).

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.

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.

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.

A spirometry study is performed in a patient diagnosed with allergic bronchopulmonary aspergillosis. An initial measurement is carried out and the patient is then put on a four-week physiotherapy treatment plan. Four spirometry measurements were taken to assess different variables and an improvement in all the spirometry values was established.

The aim of the project was to assess the acceptability of the device as well as adherence to the study. The objective of study was to assess physical activity in patients with COPD during in-hospital pulmonary rehabilitation program. The number of steps, average energy expenditure expressed in MET and kcal, and physical activity time during the consecutive 5 days of the rehabilitation stay were analyzed. Physical activity level was continuously monitored to assess intensity during in-hospital procedures as well as during leisure time.
