Autonomic Function in Patients With COPD
Autonomic Function in Patients With Chronic Obstructive Pulmonary DiseaseConduct an in-depth evaluation of autonomic function using a validated tests, assess genetic aspects of autonomic failure, and determine the correlation between of autonomic function failure and other clinical variables in patients with COPD.
Cross-Sectional Study of COPD Prevalence Among Smokers, Ex-smokers and Never-Smokers in Almaty,...
Chronic Obstructive Pulmonary Disease (COPD)The purpose of this study is to assess the prevalence of COPD among individuals aged 35 - 59 years based results of spirometry before and after bronchodilator, presence of structural changes in lungs (emphysema, inflammatory changes and thickening of the walls of the large and small airways)detected by computer tomography as well as the symptoms of COPD. The study has three study groups: smokers of conventional cigarettes; those who had quit smoking 1 - 5 years ago, and those who haven't smoked cigarettes.
EvAluation of Clinical Effectiveness Of RoLenium Administered With Elpenhaler in Chronic Obstructive...
Chronic Obstructive Pulmonary DiseaseObservational study for the evaluation of clinical effectiveness in daily clinical practice of inhaled combination of propionic Fluticasone and Salmeterol in doses (500+50)mcg - Rolenium- administered with Elpenhaler device in approximately 2000 COPD (Chronic Obstructive Pulmonary Disease) patients with a FEV1 <50% predicted normal (pre-bronchodilator), a history of repeated exacerbations and who have significant symptoms despite regular bronchodilator therapy in Greece.
Follow-up-study of COPD Patients and Healthy Controls for Evaluation of Predictive Non-coding RNA...
Chronic Obstructive Pulmonary DiseaseBetween 2012 and 2014, a cohort of 90 COPD subjects of disease severity grades GOLD I-IV as well as 60 healthy control subjects (30 smokers and 30 non-smokers) have been examined regarding different clinical and blood/ sputum derived biomarkers at the investigators' research center. This observation study will follow-up/re-examine all available subjects regarding disease course and treatment changes after 3 years (+/-6 months) for the investigation of ncRNA/ transcriptome biomarkers for their potential to indicate disease progression. In addition, biobanking of respective biosamples for potential future COPD biomarker research will be conducted.
Cognitive Dysfunction in COPD Patients : Role in the Performance of Cognitive-motor Dual Task Situation?...
Chronic Obstructive Pulmonary DiseaseChronic Obstructive Pulmonary Disease (COPD) is a respiratory disease starting point characterized by multiple systemic effects as cognitive dysfunction. This one seems to have an impact in activity daily living, considered mainly as a cognitive-motor dual task situations. Yet to date, no study has specifically focused in the cognitive-motor performance in patients with COPD or on the effects during a rehabilitation program. The main objective of this work was to evaluate the impact of cognitive dysfunction in COPD, comparing performance between COPD patients and healthy subjects in a single and dual task cognitive-motor situation. The secondary objective was to assess the impact of a rehabilitation program on these performances.
Rehabilitation in Chronic Obstructive Pulmonary Disease Outpatients
Chronic Obstructive Pulmonary DiseaseA retrospective analysis on a cohort of unselected COPD patients admitted to pulmonary rehabilitation (PR) performed in one rehabilitation centre has shown that the usual program is feasible and effective even in the presence of complex comorbidities, although some combined diseases might reduce the overall proportion of patients who respond to pre-defined outcomes criteria (Crisafulli E, et al. Thorax 2008;63:487-92). The aim of this prospective study is to describe the pattern of prevalence of the most frequently associated COPD-comorbidities and the clinical impact on rehabilitation outcomes, referred to 3 teaching and 1 private hospitals admitting for pulmonary rehabilitation purposes.
Pathophysiological Mechanisms of Dyspnea and Activity-limitation in Mild Chronic Obstructive Pulmonary...
Chronic Obstructive Pulmonary DiseaseChronic obstructive pulmonary disease (COPD) is a growing cause of death, disability and health care costs in Canada. Nevertheless, COPD remains largely under-diagnosed and under-treated, particularly in its early stages. Patients with mild COPD have variable respiratory symptoms and often go unrecognized by their caregivers. Recent studies indicate that even smokers with near normal breathing test results can have extensive small airway disease/dysfunction at rest, which becomes more pronounced during the stress of exercise thus leading to unpleasant breathing difficulty. This study seeks to better understand the nature and causes of breathing discomfort and activity limitation in a group of patients with mild COPD. The investigators will compare detailed tests of small airway function and conduct an evaluation of several key physiological parameters during the stress of exercise in patients with mild COPD and in healthy, age-matched, non-smoking control subjects. The investigators will also compare detailed physiological responses to exercise under conditions of chemical loading and mechanical unloading of the respiratory system in patients with mild COPD. The proposed study will be the first to systematically test the hypothesis that pathophysiological abnormalities in ventilatory demand, pulmonary gas exchange, small airway function, dynamic ventilatory mechanics and respiratory muscle function contribute significantly to exertional dyspnea and activity-limitation in patients with mild COPD. This study will be the first to determine if these abnormalities can be manipulated.
Assessment of Health-status of Patients With Chronic Obstructive Pulmonary Disease (COPD) on Maintenance...
Pulmonary DiseaseChronic ObstructiveTo evaluate the early (3-month) impact of the long-acting anticholinergic Spiriva HH maintenance treatment on the COPD symptoms using the novel COPD Assessment test (CAT) in the real life setting of COPD patients, previously treated with short-acting bronchodilator on regular or as-needed basis.
Inspiratory Flow Parameters of Easyhaler and Diskus Inhalers (SALIF)
AsthmaChronic Obstructive Pulmonary DiseaseThe purpose of this study is to characterise inspiratory flow parameters across 2 Easyhaler® (EH) inhaler versions and Diskus® inhaler in patients with asthma (including children, adults, and the elderly) and in patients with chronic obstructive pulmonary disease (COPD).
Effects of Exercise Training in Chronic Obstructive Pulmonary Disease Versus Alpha-1-Antitrypsin-deficiency-patients...
Chronic Obstructive Pulmonary DiseaseAlpha-1-antitrypsin-deficiencyChronic Obstructive Pulmonary Disease (COPD)-patients (caused by smoking-level) and Alpha-1-Antitrypsin-deficiency patients showed different developments during rehabilitation in regard to improvement of 6-minute-walking distance. The aim of this study is to investigate differences between training adaptations in COPD-patients and Alpha-1-deficiency patients. Both groups take part in a standardized multimodal 3-week-rehabilitation with strength and endurance training. In addition to conventional diagnostic procedures, muscle biopsies from the M. vastus lateralis will be conducted before and after rehabilitation program followed by biochemical, histochemical and immunohistochemical analysis of the probes.
