Filter by:The primary objective is to demonstrate the clinical benefits of an active strategy for the diagnosis and treatment of PE compared to usual care in patients with unexplained exacerbations of COPD who require hospital admission. The secondary objective is to assess the safety of an active strategy for the diagnosis and treatment of PE compared to usual care in patients with unexplained exacerbations of COPD who require hospital admission.
The purpose of this study is to determine whether AZD7624 can reduce acute Chronic Obstructive Pulmonary Disease (COPD) exacerbations in patients on COPD maintenance therapy with a history of frequent acute exacerbations.
The overall hypotheses of this proposal are that discrete phenotypes of HIV Chronic Obstructive Pulmonary disease (COPD) differ in their trajectories, biomarkers, and risk factors and that persistent viral infection including residual HIV is linked to HIV COPD.
Objectives (include all primary and secondary objectives) Specific Aim #1: To determine whether an air cleaner intervention to improve home air quality will improve respiratory symptoms, quality of life, lung function and reduce risk of exacerbations in former smokers with COPD. Hypothesis: An intervention using high-efficiency particulate air (HEPA) and carbon filter air cleaners in homes of former smokers with COPD will improve respiratory symptoms, quality of life, and lung function and reduce risk of COPD exacerbations compared with placebo (sham air cleaners). Specific Aim #2: To determine whether an air cleaner intervention to improve home air quality will be associated with intermediate outcome measures known to be linked with long term outcomes in COPD, including airway and systemic markers of inflammation and oxidative stress, in former smokers with COPD. Hypothesis 2: An intervention using HEPA and carbon filter air cleaners in homes of formers smokers with COPD will be associated with lower levels of markers of inflammation and oxidative stress known to be associated with adverse outcomes in patients with COPD.
The investigators are investigating the effects of traffic-related diesel exhaust on lung function and the immune system in those at risk for COPD. The individual will be exposed to either filtered air (FA) or carefully controlled levels of diesel exhaust (DE) in our exposure chamber. Post exposure the individual will complete a steady state exercise test. 24h later, a procedure called bronchoscopy (whereby a thin, flexible tube is placed down the throat and into the lungs) will be used so that samples can be collected from the lungs. After 1 month the entire procedure will be repeated with the alternative exposure.
The current definition of chronic obstructive pulmonary disease (COPD) is based on the presence of persistent airflow obstruction assessed by spirometry. About half of the subjects with mild COPD (i.e. reduced forced expiratory volume in one second (FEV1) on forced vital capacity (FVC) ratio along with normal FEV1] are asymptomatic. Subjects with symptomatic mild COPD have reduced exercise tolerance and abnormal dynamic ventilatory mechanics compared to healthy subjects. The physiological and perceptual responses to exercise of subjects with asymptomatic mild COPD are currently unknown. The purpose of this study is to assess exercise tolerance, ventilatory constraints on tidal volume expansion and dyspnoea in asymptomatic mild COPD subjects undergoing incremental cycle cardiopulmonary exercise testing (CPET) to the limit of tolerance compared with symptomatic mild COPD and healthy controls.
This study examined whether health coaches can improve the management of chronic obstructive pulmonary disease (COPD) in a population of vulnerable patients cared for in 'safety-net' clinics. The study is designed as a randomized controlled trial for patients with moderate to severe COPD. Patients were randomized into a health coaching group and a usual care group. Those in the health coaching group received 9 months of active health coaching. Outcome variables were measured at baseline and after 9 months
The purpose of this study is to determine the effectiveness of XEN-D0501 over placebo in reducing the daytime cough frequency in patients with chronic obstructive pulmonary disease (COPD). The effectiveness of XEN-D0501 placebo in reducing capsaicin cough responses, objective 24-hour cough frequency, hourly change in cough frequency, cough severity (via visual analogue scale [VAS]), urge to cough (via VAS), global rating of change scale, Clinical COPD Questionnaire (CCQ), Leicester Cough Questionnaire (LCQ), and St George's Respiratory Questionnaire (SGRQ-C) will be evaluated.
The purpose of this study was to determine whether a fixed dose combination of indacaterol and glycopyrronium (QVA149) has an impact on night-time blood oxygen levels in Chronic Obstructive Pulmonary Disease.
