Active clinical trials for "Pulmonary Disease, Chronic Obstructive"

The NOVEL Observational longiTudinal studY (NOVELTY) is an observational study of obstructive lung disease and is a multi-country, multi-centre, prospective, longitudinal cohort study which will recruit patients with a diagnosis, or suspected diagnosis, of asthma and/or Chronic Obstructive Pulmonary Disease (COPD). Patients will undergo clinical assessments and receive standard medical care as determined by their treating physician. Patients enrolled in NOVELTY will be followed up yearly by their treating physician for a total duration of three years. In addition, patients will be followed up remotely every 3 months. The NOVELTY study will collect data currently lacking to allow for multinational data collection to fill regional/local gaps and improve comparability across regions.

Airway remodelling is an abnormal tissue repair following bronchial inflammation, which contributes to none reversible pathological features, such as bronchial and peri-bronchial fibrosis. It also influences the prognosis of Chronic Obstructive Pulmonary Disease (COPD) and its mechanisms remain largely unknown. The role of fibrocytes has been demonstrated in the pathophysiology of asthma, lung fibrosis or pulmonary hypertension. However, the recruitment of blood fibrocytes and their involvement in COPD airway remodelling remain unknown. The main objective of the study is to analyse the distribution and quantify the number of the peri-bronchial and blood circulating fibrocytes in patients with different stages of COPD compared to control subjects.

Evaluate subjects in an prospective observational study Subjects will be administered scientifically validated questionnaires Determine the affect of the Portable Oxygen Concentrator (POC) on improvements in: Exercise capability, dyspnea and quality of life as primary endpoints Utilize: Baseline Dyspnea Index (BDI) Transitional Dyspnea Index (TDI) Chronic Respiratory Disease Questionnaire (CRQ) Six minute walk test (6MWT) Epworth Sleepiness Scale (ESS) The secondary endpoints will be: Rate of exacerbations, sleep quality Health care utilization (emergency room encounters, hospital admissions)

To compare the relationship between breath-hold time and the distance in a Six Minute Walking Test in chronic obstructive pulmonary disease population.

Chronic obstructive pulmonary disease (COPD) is characterized by chronic airflow limitation caused by inflammation-mediated damage to lung tissue. Although damage to lung tissue in COPD appears to be irreversible, evidence suggests that the course of COPD can be altered through measures such as smoking cessation, pulmonary rehabilitation, and the use of pharmacotherapy for bronchodilation. A primary goal of maintenance pharmacotherapy is to reduce the incidence of acute exacerbations and the associated hospitalizations and emergency department (ED) visits. Bronchodilation in COPD maintenance therapy can be accomplished with the long-acting anticholinergic tiotropium (TIO), long acting beta-agonists (e.g. formoterol, salmeterol), methylxanthines (e.g. theophylline), or combination therapy with a long-acting beta-agonist and an inhaled corticosteroid (e.g. fluticasone propionate/salmeterol [FSC]). The objective of this study is to compare the benefits of combination long-acting beta-agonist/inhaled corticosteroid therapy to long-acting anticholinergic therapy. The study compares the risk of COPD exacerbations and COPD-related healthcare utilization and costs for commercially-insured patients age 40 and older who were prescribed FSC to those prescribed TIO. The null hypothesis is that no difference exists between the costs and outcomes of COPD patients treated with TIO and those treated with FSC. The test hypothesis is that patients treated with either TIO or FSC will incur lower costs and use fewer healthcare resources for the management of COPD. The source of data for this study was the Ingenix Impact database (formerly the Integrated Healthcare Information Services [IHCIS] database). This is an administrative claims database that includes patient-level data on enrollment, facility, professional, and pharmacy services from approximately 50 million patients covered by more than 40 managed care health plans across the United States (US). The study design is a retrospective cohort study.

This retrospective database study will assess differences in the risk of re-hospitalization and other COPD-related exacerbations and costs for patients receiving fluticasone propionate/salmeterol xinafoate combination 250/50 (FSC) versus anticholinergics [i.e. tiotropium (TIO) and ipratropium or combination ipratropium-albuterol (collectively referred to as ipratropium - IPR)] post-hospitalization or Emergency Department (ED) visit for the treatment of COPD. This is a hypotheses testing study. Associations are compared between FSC and AC cohorts. Hypotheses for the primary outcome and key secondary outcomes are presented below: Specifically the study hypotheses for the primary outcome being tested were: Ho: There is no difference in risk of COPD-related hospitalization between FSC and AC Ha: There is a difference in risk of COPD-related hospitalization between FSC and AC Hypothesis for the key secondary outcome of COPD-related costs that was tested was: Ho: There is no difference in COPD-related costs between FSC and AC Ha: There is a difference in COPD-related costs between FSC and AC

The purpose of this study is to determine the prevalence of pulmonary hypertension (PH) among patients suffering from Chronic Obstructive Pulmonary Disease (COPD) and to assess the quality of life in those patients with concomitant PH compared to COPD patients without PH and those only suffering from pulmonary arterial hypertension (PAH) respectively.

Acute exacerbations of COPD remain a common cause of morbidity and are associated with a sustained increase in the normal respiratory symptoms of dyspnoea, cough, and sputum volume and purulence. It has previously been shown that a change in cough symptoms occurs in 51.7% of exacerbations in COPD. We wish to record cough during a COPD exacerbation to determine whether this can be a objective marker of exacerbation duration and severity.

A multicenter study to evaluate lung function and symptoms in subjects with COPD who have been on regular use of only one long-acting bronchodilator.

Chronic obstructive pulmonary disease (COPD) is a lung disease that is primarily caused by cigarette smoking. The breakdown of elastin, a protein found in the lungs, can cause lung damage and may contribute to the development of COPD. Some people may be more prone to elastin damage and in turn to developing COPD than others. This study will examine whether genetic factors are responsible for altering elastin function and increasing the risk of developing COPD.
