Active clinical trials for "Pulmonary Disease, Chronic Obstructive"

Exposure to Aspergillus spores is associated with symptoms of asthma or airway inflammation (Chaudhary & Marr, 2011; Smith & Denning, 2011), leading to the possible onset of severe fungal complications with acute or chronic inflammation. In patients with chronic obstructive pulmonary disease (COPD), whose main etiological factor is cigarette smoke, A. fumigatus sensitization has been reported to be related to poor lung function (Bafadhel et al., 2014). Besides, COPD patients with fungal sensitization exhibit greater granulocyte count, implying more severe inflammation (Agarwal, Gaur, & Chowdhary, 2015). Fungal cultures from sputum are frequently positive in patients with asthma or with COPD (Pashley, 2014). Fungal colonization and infection have also been suspected to be related to exacerbations of COPD, but their potential role in the pathogenesis of COPD is poorly understood (Bafadhel et al., 2014). The hypothesis is that patients with COPD have a worsening of their pulmonary symptoms after exposure to fungal spores. This study will ensure the feasibility of quantifying environmental fungal exposure in patients' dwellings. For this, an electrostatic wipe will be deposited in the living room and another one in the bedroom for 12 weeks. The wipes will be analyzed by the mycology laboratory of the Croix Rousse hospital. If the results of this first study are conclusive, it is planned to continue this analysis with a regional multicentre study.

In recent studies with musculoskeletal system disorders in chronic respiratory patients, it has been reported that postural control is affected in COPD patients. The aim of this study to investigate relationship between spinal structure and mobility an severity of dyspnea in patients with COPD.

The purpose of this study is to estimate disease-related and all-cause burden and clinical outcomes of interest following initiation of chronic obstructive lung disease (COPD) maintenance therapy with Tiotropium Bromide/Olodaterol (TIO/OLO) or Fluticasone Furoate/Umeclidinium/Vilanterol (FF/UMEC/VI).

This study looks at data from people with chronic obstructive pulmonary disease (COPD). Some used Stiolto Respimat and the others Trelegy Ellipta as their first treatment for COPD. The purpose of this study is to find out how well the treatments worked. Researchers compare the time to first COPD flare-up (exacerbation) between the 2 treatments. The study analyses anonymous data from pharmacy claims collected over 3.5 years.

The investigators examine the 15-year mortality after an admission for an exacerbation of Chronic Obstructive Pulmonary disease (COPD).

The purpose of the study is to measure changes in physical functioning in chronic obstructive pulmonary disease (COPD) patients being treated with Spiolto® Respimat® after approximately 6 weeks in routine clinical practice.

Chronic obstructive pulmonary disease (COPD) is a complex disease characterized by multiple clinical manifestations as well as co-morbidities. While COPD subjects have traditionally been classified based solely on airflow limitation (forced expiratory volume in one second [FEV1]), a new classification system was introduced in the year of 2011 by the Global Initiative for Chronic Obstructive Lung Disease (GOLD) that recommended subjects with COPD should be classified based on a combination of airflow limitation, disease impact (determined by symptom burden and activity limitation) and history of exacerbation. This approach results in the classification of subjects in four groups: A (low risk, less symptoms), B (low risk, more symptoms), C (high risk, less symptoms), and D (high risk, more symptoms). This classification system was further refined in year 2013, specifically around the history of exacerbation definition, where having ≥1 exacerbation leading to hospital admission in preceding year was added as a criteria for classification into the "high risk" C or D groups. Further, in the year 2016, there was a refinement of the disease impact criteria that suggest the use of the COPD Assessment Test (CAT) score (over the Modified British Medical Research Council Dyspnea Scale [mMRC] score) as the preferred tool to determine classification as "more symptoms" or "less symptoms". This study aims to understand subject characteristics and current treatment modalities in different groups classified by GOLD 2016 comprehensive classification system and to understand if current treatment choice is concordant with the GOLD recommendations in real life clinical practice in China tertiary hospitals. It will provide a useful point-in-time description of COPD subject characteristics and current treatment modalities in real life clinical practice in China.

Collagens are proteins present in all tissues. Besides their structural role, recent data showed that they were able to regulate many cellular functions. Many interactions occur between extracellular matrix macromolecules, especially collagen, and various cell types. These interactions can be controlled by peptides derived extracellular matrix macromolecules, called matrikines. Previous work from the investigators laboratory and others have shown that several C-terminal domain (NC1 domains) from basement membrane-associated collagens could regulate many cellular activities. Lung is an organ particularly abundant in basement membranes. It is likely that various lung diseases may affect metabolism of basement membrane associated collagens. To the investigators knowledge, no study has focused on the expression of collagen XIX α1 chain and collagen IV chains α3 and α4 chains in lung and studied possible variations of expression in various pathophysiological situations. The aim of this study are to: Study the presence of collagen IV and XIX (or fragments) in different types of sampling such as bronchoalveolar lavage, pulmonary aspiration and bronchial biopsies Evaluate quantitative variations of expression of these collagen in different pulmonary diseases, especially chronic obstructive bronchopneumopathy, infectious pneumonia, pneumonitis or lung cancer.

This study uses CT scans to assess airflow in the lung, the scan is quick, cheap and painless. The information from the scan may help doctors tell which patients are suitable to have surgery to cure early stage lung cancer. It may also help doctors tell which patients would benefit from surgery for emphysema and diagnose types of lung disease. The investigators will follow up patients who go through surgery to test how well the scan predicts the function of the lung after surgery. The investigators will follow patients being investigated for lung disease to test how accurate the scan is at the getting the diagnosis right.

This is an observational study which aims to evaluate the possibility of using data from a capnography device to assess obstructive airway severity in both Chronic Obstructive Pulmonary Disease (COPD) and Asthma patients.
