Active clinical trials for "Lung Diseases"

Patients with COPD (chronic obstructive pulmonary disease) suffer from episodes of acute exacerbations leading to additional morbidity and mortality, and also a further decline in lung function. It has been well-established that bacterial colonization is prevalent in COPD, especially in moderate to severe COPD, and airway bacterial colonization is known to play an important role in the development of pneumonia and exacerbations. On the other way, inhaled corticosteroid (ICS) and long acting β2 agonist (LABA) were recommended in the treatment of moderate to severe COPD. Though there were some evidences that ICS had some protective effects on airway mucosa against bacteria invasion, the locally immunosuppressive effects of ICS is still a concern. Indeed, the incidence of pneumonia was higher than the control group, not only in the Towards a Revolution in COPD Health (TORCH) study but also in various studies and meta-analyses.We hypothesized that airway bacteria colonization is associated with disease severity, and that disease status can be identified by CAT (COPD assessment test)scores and changes of CAT scores. We therefore conducted this prospective, observational study in which CAT scores and sputum cultures were assessed in moderate to severe COPD patients with the combination therapy of ICS and LABA every three months during the study period. The primary end-point is the condition of potential pathogenic microorganisms (PPM) colonization in view of CAT scores. The second end-point was the changes of PPM colonization in association with CAT changes during follow-up. By the mean of CAT follow-up, it could possibly provide a surrogate about the risk of exacerbation and pneumonia under the combination therapy of ICS and LABA.

Chronic Obstructive Pulmonary Disease (COPD) is a prevalent disease. In the investigators country, underdiagnosis has been estimated in around 80% of subjects. Early detection is done mainly in primary care but due to actual situation new alternatives have been proposed to decrease underdiagnosis. This present study promote by a multidisciplinary research team (respiratory medicine, primary care, nurse and pharmacist) raise the objective of evaluate the effect of a COPD case finding program guide by spirometry in community-pharmacies. From the results of a pilot-study conducted in 13 community-pharmacies in Barcelona, in which the investigators showed the feasibility of spirometry in community-pharmacies for the early detection of COPD, the investigators have design a second phase to evaluate the effect of this strategy. 100 Barcelona's community-pharmacies during 6 months will select high risk customers and will conduct a spirometry in agreement with the design protocol. 3600 spirometries is the establish objective. Participants hospitals will train pharmacist in spirometry and also control spirometry quality daily by a telematic pathway. Spirometry results will be evaluate in terms of effect and costs. The investigators will also evaluate the impact of this program in the health system by numbers of subjects diagnosed and follow up in primary care.

Most patients with chronic lung disease underestimate their actual walking ability due to low confidence. To better understand the relationships between lung function, self-efficacy for walking (confidence in ability to walk a defined distance), actual walking ability for the same distance gait speed and physical activity level-PAL- (total energy expenditure/resting metabolic rate). Quality of life, self efficacy for activity questionnaires, physical activity level measurement, 4-meter gait speed and 6-minute walk distance will be measured.

Chronic obstructive pulmonary disease (COPD) is a progressive and largely irreversible lung disease characterized by chronic bronchitis and/or emphysema, resulting in breathlessness, cough and sputum. As COPD progresses, patients experience increasing deterioration of their health-related quality of life, with greater impairment in their ability to work and declining participation in social and physical activities. The aim of this non-interventional study is to evaluate data on quality of life in COPD patients in Germany in a real life medical setting under therapy with the phosphodiesterase-inhibitor (PDE-4) roflumilast (Daxas). Evaluation is based on two COPD specific questionnaires to assess the patient's health status over six months. During the study, lung function measurements such as spirometry will be conducted according to common medical standard. Daxas (tablet) will be administered once daily. The study will provide further data on the safety and tolerability of Daxas.

The main purpose of this study is to evaluate the sensitivity of a new oxygen enhanced magnetic resonance imaging (OE-MRI) method in detecting changes in the lungs of patients with moderate to severe chronic obstructive pulmonary disease (COPD) following treatment with either Oxis Turbuhaler or Symbicort Turbuhaler.

It is well established that steroid use is a benefit in the treatment of chronic obstructive pulmonary disease (COPD) with acute exacerbation (AE). But it is still debated about the regimen and dosage of steroid use. From this retrospective review of medical charts, the researchers investigated the therapeutic impact of various steroid dosages in COPD with AE.

HIV-infected patients have an increased incidence of emphysema compared to non-HIV-infected patients, and it has been hypothesized that this accelerated disease progression is the result of one or more latent infections that amplifies the pulmonary inflammatory response. The investigators will examine the prevalence and progression of emphysema in subjects with and without HIV and determine risk factors for emphysema in this population.

Chronic obstructive pulmonary disease (COPD) is a condition that is characterized by airway obstruction due to inflammation. Levels of inflammatory proteins may be linked to when and to what extent COPD develops. This study will use data collected during the Tucson Epidemiological Study of Airway Obstructive Disease (TESAOD) and its 33-year follow-up to determine the relationship between inflammatory protein expression and COPD.

The aim of the study is to test the hypothesis that treatment of sleep disordered breathing (SDB) in patients with comorbid chronic obstructive pulmonary disease (COPD) and/or heart failure (HF) with positive airway pressure (PAP) is associated with reduced risk for hospitalizations and death, lower health care utilization, and greater cost-effectiveness.

COPD patients often have a wide range of physical (e.g., dyspnea, fatigue, pain) and psychological (e.g., depression, anxiety) symptoms and various other debilitating conditions that cause considerable suffering for the individual. Unfortunately, many of the symptoms and health problems in patients with COPD are unrecognized and untreated. Due to the irreversible nature of COPD, the aim is not to cure the disease, but to reduce symptoms and improve quality of life. Therefore, the purpose of this project is to investigate the existence and nature of symptom clusters over time in patients with COPD and their effects on patient outcomes. Since this study aims to identify possible new subgroups of patients with COPD defined by the clustering of certain symptoms, the study also aims to investigate the relationship between the clinical presentation and certain immunologic and genetic factors.
