Filter by: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.
Obstructive lung disease is an increasing global health problem of pandemic proportions, with COPD alone affecting >10% of the population. Smoking is the main and most well studies risk factor for developing COPD. However, chronic airway obstruction also in never-smoking populations has recently been recognized as an increasing health problem. In the clinical segment (PI: Prof. C. Magnus Skold), 1000 subjects from the Swedish national SCAPIS study will be clinically well characterized in one of the six Swedish University Hospital Respiratory clinics (clinical site PIs: Anders Andersson, Leif Bjermer, Anders Blomberg, Christer Janson, Lennart Persson, Magnus Skold). This first screening includes all never-smokers with COPD identified in the SCAPIS study. A subset of 300 subjects from the groups of Healthy never-smokers, current-smokers with normal lung function, current-smokers with COPD, ex-smokers with COPD, and never-smokers with COPD will be selected for the Bronchoscopy segment, were sampling will be performed from a number of anatomical locations, including bronchial biopsies, airway epithelial brushings, and bronchoalveolar lavage. Serum, plasma, and urine samples will also be collected. In the systems medicine segment (PI: Assoc. prof Asa M. Wheelock), alterations at the epigenetic, mRNA, microRNA, proteome, metabolome and microbiome level will be performed from multiple lung compartments (airway epithelium, alveolar macrophages, exosomes, and bronchoalveolar exudates). By means of biostatistics and bioinformatics approaches, specific mediators and molecular pathways critical in the pathological mechanisms of obstructive lung disease related to never-smoker disease phenotypes will be identified. In the immunohistochemistry segment (PI: Prof. Jonas Erjefalt), a number of molecules of relevance for disease pathology will be investigated in bronchial biopsies collected from the 300 subjects in the Bronchoscopy segment.
Chronic obstructive lung disease is a disabling disease that affects people usually after several years of smoke tobacco exposure and affects millions of patients worldwide. The disease is marked by multiples episode of worsening, termed exacerbations necessitating frequent hospitalizations. During these exacerbations, patients present breathless, and in the most severe cases, are admitted to an Intensive Care Unit (ICU) for respiratory assistance. Currently, respiratory assistance is provided by a ventilator via a oronasal mask (referred to non-invasive ventilation, NIV), that helps patients to cope with their breathless. The mask is not always well tolerated and the ventilator sessions are delivered intermittently. In the past decade, a new technique that provides air-oxygen with high flow has been developed. This technique, called High Flow via Nasal Cannula (HFNC) can deliver from 21 to 100% heated and humidified air-oxygen at a high flow of gas via simple nasal cannula. Recent studies have shown that the technique is very efficient to treat patients presenting with acute respiratory failure who don't have any underlying chronic pulmonary disease. Whether the technique would be also efficient in patients with COLD presenting with severe exacerbations has not yet been demonstrated. Since HFNC does not require any mask, it is thought that the comfort of the patient would be much better in comparison to NIV and could potentially help to treat many patients with the disease. The objective of the present study is to study the physiological effect of HFNC as compared to NIV in patients with severe exacerbations of COPD and to show that it is non-inferior to NIV.
Using an extensive set of both volitional and non-volitional tests of respiratory muscle function and strength it is the aim of this study to - identify disease-specific patterns of respiratory muscle impairment in different NMD and COPD - establish which set of tests is predictive of sleep-disordered breathing or daytime hypercapnia in patients with NMD or COPD, respectively. - to investigate the decline of respiratory muscle function in patients with progressive NMD and COPD along with sleep studies and capnography
Preliminary studies have shown that NPPV can avoid tracheal intubation in 40% to 60% patients who have severe exacerbation of COPD. Recently, large-scale comparative effectiveness research (CER) also found that compared with invasive ventilation, NPPV can reduce mortality rates. But there's no high-quality clinical studies which can confirm this. Therefore, investigators believe that NPPV can avoid intubation in patients with severe exacerbation of COPD in ICU with perfect monitoring conditions and reasonable human resource allocation, in order to reduce IMV-related complications and improve patients' outcomes.
