Filter by: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.
Rehabilitation and physical therapy strategies targeting extra pulmonary manifestations of Chronic Obstructive Pulmonary Disease (COPD)are far from being well defined. Studies, performed in healthy subjects using threshold breathing device [a simple method to increase inspiratory muscle load] have shown that ventilatory muscle overactivation during loaded breathing may prime reactive oxygen species (ROS) production, thus initiating an inflammatory response that results in elevation of pro-inflammatory cytokines, particularly IL_6. Increase of cytokine IL_6 in turn, elicits a cascade of systemic responses, involving hormone like glucoregulatory mechanisms, lipolysis and fat oxidation, as well as control of breathing. Thermal mud bath therapy has been acknowledged for its antioxidant and anti-inflammatory effects in several chronic diseases. However, it is not considered among treatment options of chronic pulmonary disease. Previous experimental studies indicate that trace elements of thermal treatments, particularly iodide and bromide, may positively intervene in the setup and maintenance of active state in skeletal muscle. These findings suggest that in COPD patients these elements may improve the loading and endurance of respiratory muscles and therefore blunt ventilatory muscle overactivation and the ensuing inflammatory cytokine response. In this study the investigators want to test two major hypotheses. First, that mud bath therapy reduces systemic inflammatory processes in COPD patients, increases respiratory muscle endurance and normalizes the ventilatory response. Second, that the increase in systemic inflammation after IRB exercise is blunted by mud bath therapy.
COPD patients frequently suffer intermittent exacerbations of their disease characterised by acute deterioration of symptoms. Acute exacerbations of COPD (AECOPD) are associated with significant impairment of health status, use of health care resources, poor prognosis and increased mortality. The development of simple and practical predictive tools would help to identify COPD patients at greater risk of suffering exacerbations, which is important since those patients would need more intense and early treatment. This one-year prospective cohort non-drug study will evaluate several COPD-specific questionnaires as predictive tools and the presence of cardiovascular comorbidities as risk factors, for the composite events in study cohorts. The trial duration consists of a screening period (4-6 weeks) and a follow-up period (12 months), 4 visits in total along the study.
The purpose of this study is to determine the effect of a tablet medication, called metformin, in flare-ups (exacerbations) of chronic obstructive pulmonary disease. The investigators believe that metformin may effectively control the blood sugar level during COPD exacerbations. This is important because there is evidence that a high blood sugar level during exacerbations may be linked with a worse prognosis. The investigators also think that metformin may have other potentially useful effects on inflammation, antioxidant levels, the effectiveness of steroid treatment, and recovery.
The purpose of this study is to determine the prevalence and severity of extrapulmonary disorders and to quantify the impact of extrapulmonary organ manifestations on morbidity and mortality of COPD patients. Furthermore the investigators evaluate the relationship between systemic inflammation and organ involvement.
The purpose of the present study is to determine the effects on health status and spirometric values of Foster® 100/6 (two puffs b.i.d.) versus Seretide® 500/50 (one inhalation b.i.d.), over a 12-week treatment period in Chronic Obstructive Pulmonary Disease (COPD) patients.
To determine the efficacy and safety of Salmeterol/Fluticasone Propionate 50/500ug BID vs Ipratropium/Albuterol 36/206ug QID in Chinese patients with moderate-to-severe Chronic Obstructive Pulmonary Disease (COPD).
The purpose of this research study is to perfect the technique of EVLP and learn about the safety of transplanting lungs that have been ventilated (attached to a breathing machine or ventilator to deliver oxygen) and perfused with a lung perfusion solution (Steen solution™, made by Vitrolife). This ventilation and perfusion will be done outside the body (ex-vivo) in a modified cardiopulmonary bypass circuit (the kind of device used routinely during most heart surgeries). The purpose of performing ex-vivo lung perfusion and ventilation (EVLP) is to learn how well the lungs work, and whether they are likely safe to transplant.
The goal of the study is to evaluate a Home-Based Disease Management program specifically developed for patients with Gold III/IV COPD. By improving disease knowledge, awareness of significant clinical deterioration and self-management skills for patients, this Home-Based COPD Management Program is expected to reduce the severity of exacerbations, the need for emergency hospitalisations, thus demonstrating the efficacy and the cost effectiveness of this intervention.
This project will evaluate the translation of the Gold (the Global Strategy for the Diagnosis, Management, and Prevention of Chronic Obstructive Pulmonary Disease) COPD guidelines into primary care practice. During phase I, a needs assessment will evaluate barriers and facilitators to implementation of COPD guidelines into clinical practice through focus groups of primary care patients and providers. Using formative evaluation and feedback from the focus groups, three tools will be developed, refined and pilot tested. The effectiveness of the materials developed in phase I will be tested in phase II (a randomized clinical trial conducted with one year of intervention within non-academic primary care practices) regarding physician performance of COPD guideline implementation and improvement in the clinically relevant outcomes (appropriate screening, diagnosis and management of COPD) compared to usual care.
