Active clinical trials for "Pulmonary Disease, Chronic Obstructive"

Assess the feasibility of using remote respiration rate monitoring as a component of home care, how respiration rate data may be used in combination with other data to potentially improve response to symptoms, and to generate data to inform the endpoints and effect sizes of future studies.

The investigators will conduct a randomized, controlled, double-blind, crossover trial to determine whether the presence of a portable high-efficiency indoor air filter in the bedroom reduces respiratory symptoms in former smokers compared with placebo. The primary outcomes will be change in St. George's Respiratory Questionnaire - COPD (SGRQ-C) score associated with using a portable high-efficiency indoor air filter during the study period. Secondary outcomes of COPD exacerbations and hospitalizations, daily step counts, medication changes, spirometry, and cardiovascular outcomes will also be assessed.

The purpose is to study the correlation between systemic inflammation (serum levels of CRP, IL-1beta, IL-6 and TNF-alpha) or hyperhomocysteinemia and the increase of mortality, in a representative cohort of patients with chronic obstructive pulmonary disease (COPD). Secondary purposes are: To confirm the increase of cardiovascular mortality and the importance of cardiovascular morbidity in patients with COPD, To establish the role of various genetic polymorphisms in the correlation between systemic inflammation and cardiovascular disorders observed in COPD, To search for acceleration of aging of cardiovascular system evaluated with carotid intima-media thickness when systemic inflammation markers are increased, To study the correlation between COPD risk factors (tobacco and other food factors), change of respiratory functional data and cardiovascular morbi-mortality. In this study cardiovascular morbi-mortality is defined by following disorders: ischemic cardiopathy, left-sided heart failure, cardiac arrhythmia and cerebrovascular accident. Diagnosis is confirmed with standard techniques and independently of this study. Results of clinical examination, ECG, echocardiography and /or brain scanner will be collected.

Randomized, placebo controlled trial evaluating the effect of acetazolamide on cognition in lowlanders with chronic obstructive pulmonary disease travelling from 760 m to 3200 m.

This trial will evaluate the effect of acetazolamide (375 mg per day) vs. placebo on right ventricular function during exercise at acute altitude exposure in patients with COPD.

In this trial, the investigators will evaluate the effect of acetazolamide (375 mg per day) vs. placebo on sleep related breathing disturbances at altitude in patients with COPD.

The present study aims to assess the prevalence and impact of comorbid psychiatric disorders among patients with chronic obstructive pulmonary disease (COPD) undergoing pulmonary rehabilitation (PR), in order to determine the effects of psychiatric comorbidity on exercise tolerance and physical activity post-PR and HRQoL, as well as to determine the processes by which these psychiatric disorders may impact on these patient behaviours.

This study will assess the safety, tolerability, pharmacodynamics, and pharmacokinetics of RO5024118 following repeated inhalation in patients with moderate-to-severe Chronic Obstructive Pulmonary Disease (COPD). Patients will be randomized to receive multiple inhaled doses of R7103, as compared with placebo. The target sample size is approximately 30 individuals.

This is a randomized, double blind, placebo controlled, parallel-group, 7 day repeat dose study to investigate the safety, tolerability, pharmacokinetics and pharmacodynamics of inhaled dose of GW642444M from a novel dry powder device in healthy Japanese male subjects.

This is a parallel group, double-blind, placebo controlled, multi-centre, randomised trial. 60 patients to be included who are adult patients admitted to hospital with a clinical diagnosis of acute exacerbation of Chronic Obstructive Pulmonary Disease (COPD). Acute exacerbation of COPD will be defined as sustained worsening of the patient's condition with an increase in cough and one or more of dyspnoea, sputum volume or sputum purulence, necessitating a change in regular medication. The primary objective of this study is to evaluate the effectiveness of standard care plus erdosteine in reducing hourly cough (24 hour cough recording using automated cough recorder) measured from baseline (Day 0) and at Day 5 of treatment, compared with standard care plus placebo.
