Active clinical trials for "Lung Diseases"

In COPD the patient's ability to use inhalers correctly and their preference for the inhaler are both important factors in selecting an appropriate treatment for COPD. This is a cross-sectional study where satisfaction, preference and handling of two different devices such as Respimat and Breezhaler will be evaluated by using the validated PASAPQ in COPD patients

TOPDOCS is a prospective cohort study including COPD patients from currently six study centers in Switzerland. Patients with COPD GOLD stages I-IV will be enrolled and followed-up annually for at least 3 years. Yearly assessments will include a detailed patient history, quality of life and activity questionnaires, history of exacerbations, lung function, measurements of exercise capacity, measurements of vascular function, exhaled breath analysis and blood sampling. The overall objective of the project is to establish a meticulously characterized cohort of COPD patients living in Switzerland in order to allow high quality research on the pathogenesis, treatment and complications of COPD. The specific aim of the project is to determine clinically relevant COPD phenotypes and biological factors influencing vascular function in COPD patients.

VESALIO is a pilot study aimed at evaluating the feasibility and reliability (time stability and interobserver reliability) of healthcare quality standards in chronic obstructive pulmonary disease (COPD) recently outlined by SEPAR (Spanish Pneumology and Thoracic Surgery Society), and at establishing the foundation for a future validation (construct and criterion validation) of the aforementioned standards.

This is a prospective, observational, non-drug interventional, non-randomized study to compare the rate of moderate-severe COPD exacerbations in patients of all Chronic Obstructive Pulmonary Disease (COPD) severities with and without cardiovascular diseases. A total study population of 3330 subjects will be recruited by general practitioners (GPs) and assessed over a 27 month time frame.

A pharmaco-epidemiological, observational study that aimed at assessing in a prospective manner the evolution of Quality of Life (QOL) in chronic obstructive pulmonary disease (COPD) patients treated with inhaled bronchodilators

The purpose of this study was to investigate the prevalence of chronic bronchitis in patients suffering from moderate to very severe chronic obstructive pulmonary disease (COPD), and to assess the difference in exacerbation rates in patients suffering from moderate to very severe COPD with chronic bronchitis vs. a population of patients without chronic bronchitis.

The purpose of this study is to create a prospective database of all patients who have undergone pulmonary function testing from which the investigators can study the clinical phenotypes of various respiratory conditions. The investigators hope by understanding the differences in these myriad phenotypes to be able to provide individualized, patient-targeted therapy in the future.

Chronic obstructive pulmonary disease (COPD) is characterized by a progressive decline in lung function and increased symptoms such as breathlessness/dyspnoea, cough and expectoration. Even though subjective in nature, the symptomatology of COPD and mainly that of breathlessness/dyspnoea has been studied with the use of objective measurement tools. Taking into consideration that the symptoms experienced by the patient who suffers from a progressive disease such as COPD can only be perceived and interpreted by the patient him- or herself, and thus difficult to be quantified, COPD remains a challenge in clinical research. Therefore, there is a need to carry out qualitative studies that will provide insight into the wide spectrum of COPD symptomatology from the patient's perspective. In addition, a further mapping of the impact that COPD symptoms' perception has on a patient's life is required, as well as of the different pathways through which symptoms' perception is interpreted regarding the limitations of daily living activities, and the subsequent impact on disease management. The more the physician learns on the embodied experience of COPD, the better he/she may assist the patient in achieving optimal COPD management. Thus this cross-sectional observational study was designed aiming to obtain these data. Specifically, the study aims to evaluate the most frequently used words by the patients and the physicians to express the symptoms of COPD as well as the limitation of activities that it causes.

Assessment of the inhalation profiles of four dry powder inhalers in patients with variable degrees of lung obstruction

COPD exacerbations are characterized by an excessive accumulation and activation of inflammatory cells in the airways. It is not known whether this phenomenon represents a risk for for lung damage via the release in the extracellular environment of potent cytolitic cellular granular contents such as granzymes and perforin. The investigators assess the intracellular expression of granzymes and perforin in neutrophils and large granular lymphocytes (LGL) at the onset of exacerbations compared to stable disease. The investigators hypothesize that a greater release of intracellular perforin and granzymes from neutrophils and LGL into the extracellular environment occur at exacerbations compared to stable condition and that these changes are more pronounced in COPD patients than in subjects without COPD who undergo respiratory infection.
