Filter by:In this 5-months study, the response of patients to salbutamol at baseline will be compared with their response to treatment with indacaterol.
The cardiovascular component associated with COPD plays a major role in prognosis of the disease, being responsible of 25% of the deaths. Experimental and initial clinical data suggest that beta-adrenergic agonists accelerate clearance of excess fluid from the alveolar airspace, with potential positive effect on cardiogenic pulmonary edema. The aim of this study was to investigate the effects of a long-acting beta-2 agonist, salmeterol, on alveolar fluid clearance in COPD patients by evaluating the diffusive and mechanical lung properties. Our experimental model to test alveolar fluid clearance was rapid saline intravenous infusion. Ten COPD and 10 healthy subjects treated with salmeterol or placebo 4 hours before the begin of the study were evaluated, in four non consecutive days, just before and after a saline infusion or a similar period without infusion. Both in COPD and healthy subjects rapid saline infusion, with placebo or salmeterol premedication, lead to a significant decrease of DLCO and FEV1. Nonetheless, salmeterol pretreatment lead to a significant reduction of the impairment of gas exchange due to saline infusion (-64% of DLCO reduction in comparison with placebo), whilst it did not affect the changes in FEV1. In the control setting, with no infusion, we did not find any significant change of both DLCO and mechanical properties of the lung. In conclusions, in COPD patients salmeterol appears to provide a protective effect against an acute alveolar fluid clereance challenge secondary to lung fluid overload providing an intriguing mechanistic explanation for the benefits observed in larger trials.
Hypothesis: Can a counseling intervention, delivered by a pharmacist, increase inhaler adherence in veterans with COPD who have demonstrated poor inhaler adherence through pharmacy refill records? Veterans who receive who receive daily maintenance inhalers from the William S Middleton Memorial Veterans Hospital Pharmacy and who have a medication possession ratio less than 80% over the previous six months will be invited to participate in the study. This study will randomize 100 participants to a usual care arm or a pharmacist counseling intervention. Final data collection will be six months after randomization to determine if both self-reported and refill record adherence has changed.
The primary objective of this study is to identify biomarkers that can be used for evaluation of efficacy in subjects presenting with AECOPD
Observational study to know the Impact of morning symptoms in clinical control of COPD patients. 1200 patients will be included by General practitioners (GPs) and pneumologists. Objective: establish if there are differences in the impact of COPD on daily activities and morning symptoms measured through questionnaires of daily life activity (Capacity of Daily Living during the Morning (CDLM), Global Chest Symptoms Questionnaire (GCSQ))
The aims of this study are:1.To evaluate the utility of quadriceps RMNMS (repetitive magnetic neuromuscular stimulation) in the evolution of COPD patients after hospital admission for acute exacerbation.2 To evaluate the time schedule of recovery changes in muscle parameters ,exercise capacity and quality of life after acute exacerbation. 3.To test the use of this new method of training in acute clinical situations. Patients: COPD patients admitted to the Hospital with acute exacerbation. Group 1: RMNMS Treatment .Group 2 : sham RMNMS treatment. Randomized assignment by minimization method. PROTOCOL Training Group: 10 days after discharge and during 8 weeks, 2-3 days/week. Measures: Spirometry, Plethysmography ,Diffusion Test. Main outcomes: Exercise test (Six minutes walking distance). Muscle function: MVC. Health related quality of life.
This study compares the cardiac safety of inhaled indacaterol with that of placebo and oral moxifloxacin.
The investigators will describe the characteristics, prevalence, incidence, severity co-morbidity and management of patients with chronic obstructive pulmonary disease (COPD) in the UK. 100 practices will be sampled amounting to a total study population of about 10 000 patients. Information will be collected electronically and, where necessary, by a hand search of patient records.
This study would like to test the hypothesis that a pharmaceutical care intervention would result in an improved drug adherence and inhalation technique in Chronic Obstructive Pulmonary Disease (COPD) patients over a 3 month-period.
The purpose of this study was to compare the self-efficacy and quality of life parameters of Chronic Obstructive Pulmonary Disease(COPD)patients who underwent pulmonary rehabilitation with and without Tai Chi elements incorporated in the exercise component in a General Out-patient setting.
