Filter by:The primary objective is to investigate the efficacy of resveratrol on mitochondrial function in patients with COPD. The secondary objective is to investigate the effect of resveratrol on body composition, inflammatory status and mechanistic markers in blood, adipose and muscle tissue as well as a comprehensive assessment of metabolicand physical performance profile known to be affected by resveratrol.
The coexistence of chronic obstructive pulmonary disease (COPD) and obstructive sleep apnea (OSA) in the same patient has been termed overlap syndrome, affecting 1% of the U.S. population.The investigators propose to conduct this study that aims: (1) to compare right and left ventricular hemodynamic parameters using cardiac magnetic resonance imaging (MRI) in overlap syndrome vs. COPD only and OSA only; (2) to compare the effects of bi-level positive airway pressure (BPAP) vs. nocturnal oxygen therapy (NOT) on right ventricular (RV) hemodynamics in overlap syndrome. This study will allow us to test the hypothesis: (1) Patients with overlap syndrome have more RV dysfunction than those with COPD only or OSA only; (2) treatment of both hypoxemia and hypercapnia during sleep will improve RV hemodynamics compared with treatment of hypoxemia alone in patients with overlap syndrome.
The primary objective of this trial was to establish non-inferiority of lung function response to tiotropium 10 μg, formulated as inhalation powder in the polyethylene hard capsule and delivered via the HandiHaler® 2, compared to tiotropium 18 μg, formulated as inhalation powder in the hard gelatine capsule and delivered via the HandiHaler® (Spiriva®) following single dose inhalation in patients with COPD. A hard polyethylene (PE) capsule with half the strength (tiotropium 5 μg) was included to investigate a dose ordering effect. The secondary objectives were to characterize the pharmacokinetics of tiotropium inhalation powder hard PE capsule (delivered via HandiHaler® 2) and tiotropium inhalation powder hard gelatine capsule (delivered via HandiHaler®) and to compare the safety of the two pharmaceutical formulations.
The primary objective of this trial was to establish non-inferiority of lung function response to 25 μg salmeterol, administered as the xinafoate salt, in an inhalation powder delivered from hard polyethylene (PE) capsules via the HandiHaler® 2 compared to Serevent® Diskus® (salmeterol 50 μg, administered as the xinafoate salt) following single dose inhalation in patients with COPD. The secondary objectives were to characterize the pharmacokinetics of salmeterol inhalation powder delivered by HandiHaler® 2 from the PE hard capsule and salmeterol xinafoate delivered by Serevent® Diskus®, and to compare the safety of the two pharmaceutical forms.
Assessment of health-related quality of life in COPD patients with severe chronic respiratory failure requires appropriate and highly specific measurement tools. We attempt to validate the Chinese version of the Severe Respiratory Insufficiency Questionnaire (SRI)
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.
