Filter by:COPD and sleep apnea dyspnea syndrome represent two of the most common chronic lung diseases. It is reported that the prevalence of COPD with sleep apnea dyspnea syndrome is also very high. COPD and sleep apnea may have pathological or genetics interactions so that patients having both disorders tend to have worse outcomes than either condition alone. Data reflecting the prevalence, disease course and outcome of overlap syndrome is very limited in China. Therefore, the aim of the study is to describe the prevalence, treatment and outcome in Chinese patients and exploring the underlying interaction mechanism.
To Assess the Utility of Impulse Oscillometry on a Differential Diagnosis among the Patients with ACOS,asthma and COPD over Age 40.
Bronchial basal cells are proved to be able to regenerate lung structures to repair the injured lung. In COPD patients, bronchus structures are injured and cannot be repaired, which may result in the failure of pulmonary function rescue clinically.In our research, autologous bronchial basal cells will be transplanted into lung of patients suffered with COPD to treat the disease. Specifically, autologous bronchial basal cells will be dissected from brushed-off samples by bronchofiberscope. Then, they will be expanded in vitro and transplanted into lung to regenerate new alveoli and bronchus structures and re-establish pulmonary system.
Chronic Obstructive Pulmonary Disease (COPD) is characterized by chronic and progressive airflow limitations and subjects with COPD also experience exacerbations characterized by the worsening of respiratory symptoms. It's necessary medical intervention, changes in regular medication, and the use of antibiotics and/or corticosteroids followed or not by hospitalization. The exacerbations contribute to worsening of the disease with systemic impairment and muscle weakness is a very relevant event. The physical inactivity, especially related to bed rest, comprises one of the factors contributing to muscle atrophy and loss of muscle strength. Thus, the intervention performed during hospitalization is necessary to minimize the consequences which causes impairment in health status subjects. The aim of the study is assess the effect of the intervention with elastic bands, in muscle strength,level of the physical activity, functional capacity, dyspnea on activities of daily living (ADL) and quality of life in COPD exacerbation subjects. Moreover,verify the intervention benefits over 01 and 03 months post exacerbation episode. It will be a prospective, randomized, longitudinal and interventional study. The investigators will be asses both gender patients with exacerbation of COPD in 4 situations: First time (at least 24 and at most 48 hours after the beginning of medical therapy); seven days post the first assessment; one and three months post exacerbation episode. It will be assess the muscle strength, physical activity level, functional capacity, dyspnea on ADL and quality of life. The patients will be randomized in 2 groups: intervention and control group. The intervention will be performed with elastic bands once a day during seven days. The investigators expected that patients of the intervention group will present better muscle strength, physical activity level and functional capacity than the control group. Furthermore, an improvement in dyspnea and quality of life is expected in intervention group when compared as with control group patients. It is hypothesized that the benefits of intervention will be maintained over one month.
This is the registry of control participants for patients with various respiratory diseases. We screened healthy volunteers who visited Seoul National Hospital Healthcare System Gangnam Center for routine health check-up, and enrolled patients who agree to participate in the study. The participants undergo baseline questionnaires, provide blood specimen and information of the results of health check-up. We will include participants as controls if they have no significant respiratory symptom and no significant radiographic abnormality. The data from this registry will be compared with those from other registry of various respiratory diseases
Chronic Obstructive Pulmonary Disease (COPD) is a kind of chronic bronchitis or emphysema with characteristics of long-term poor airflow, resulting in chronic pulmonary heart disease, chronic respiratory failure or even death. Anatomically, the pulmonary bronchus structures in COPD patients are damaged and cannot be repaired by recent clinical treatment so far. This study intends to carry out an open, single-armed, phase I/II clinical trial to investigate whether bronchial basal cells can regenerate damaged lung tissue. During the treatment, bronchial basal cells will be isolated from patients' own bronchi and expanded in vitro. After careful characterization, cultured cells will be transplanted autologously into the lesion by fiberoptic bronchoscopy. The safety and efficacy of the treatment will be monitored by measuring the key clinical indicators.
Patients with COPD are more inactive and more sedentary than subjects of the same age and patients with other chronic diseases. This inactivity and sedentary behavior is accentuated after hospitalizations due to a COPD exacerbation, and it increases the risk for future hospitalizations and mortality. Therefore, there is a need for intervention to promote physical activity and to reduce sedentary behavior after these events. The present study aims to evaluate the efficacy of a coaching program to promote physical activity and reduce sedentary behavior in patients with COPD who have suffered a hospitalization due to a COPD exacerbation. Sixty-six COPD patients admitted to the hospital will be recruited during 18 months. Physical activity, sedentary behaviors, as well as other clinical and functional parameters will be evaluated after hospital discharge. Patients will be then randomized to an intervention and control group (1:1). The intervention group will receive an individualized coaching program. During a motivational interview an experienced physiotherapist will asses participant's usual exercise habits, possible barriers and facilitators, self-efficacy and motivation to increase physical activity and reduce sedentary time. Based on these data (and baseline physical activity/sedentary information) an individualized, progressive program with specific goals setting and self-monitoring will be established (patients will be active participants and decision makers in this process). The control group will receive the usual care during follow-up. Physical activity, sedentary behaviors, as well as the clinical and functional variables will be evaluated again at 12 weeks in both patients' groups.
The primary purpose of this study is to show whether at home usage of the AIRVO warm humidifier can potentially reduce the number of exacerbations in patients with significant respiratory insufficiency. Eligible participants of the study must have a diagnosis of chronic obstructive pulmonary disease (COPD) stage II-IV..
This project is aimed to assess the responsiveness of the Glittre ADL-test and the 1-Minute Sit-to-Stand test (1-Minute STST) to acute bronchodilation in patients with COPD. We also aim to investigate the physiological and perceptual response to bronchodilation of the Glittre ADL-test and the 1-minute STST. The specific objectives are 1)To measure the changes in time for completion of the Glittre ADL-test and the number of standing up during the 1-minute STST induced by a single dose of nebulized ipratropium bromide/salbutamol sulfate against those induced by a placebo in patients with moderate to severe COPD and 2)To compare in patients with moderate to severe COPD the CR (minute ventilation (VE), oxygen uptake (VO2), carbon dioxide production (VCO2) and heart rate) and symptomatic (dyspnea and leg fatigue perception) responses during the Glittre ADL-test and the 1-Minute STST following a single dose of ipratropium bromide/salbutamol sulfate or placebo. We suppose among others that the Glittre test completion time will be lesser, that the number of repetitions in the 1-Minute STST will be higher and symptoms intensity will be lesser among patients with COPD receiving bronchodilators.
This phase II single centre, double blind, placebo-controlled, randomised trial aims to test the hypothesis that intravenous iron improves exercise performance in Chronic Obstructive Pulmonary Disease (COPD) as measured by constant rate cycle ergometry.
