Filter by:Hypothesis: The first part of the study is a survey on the prevalence of anemia of chronic disease (ACD) among COPD patients. The 2nd and 3rd part will test 2 null hypotheses (Ho): 1.serum inflammatory markers and plasma erythropoietin do not differ between COPD patients with and without ACD and 2. exercise capacity does not differ between COPD patients with and without ACD. Rationale-Aim: ACD is an immune driven disorder, developing in subjects suffering from chronic inflammatory diseases. COPD is a disorder very likely to be associated to ACD due to its systemic inflammatory dimension. Currently, data on the prevalence of ACD and on the level of inflammatory markers which are implicated in the pathogenesis of ACD in COPD subjects are limited and controversial. Furthermore, there is no data on the effect of ACD on exercise capacity of COPD subjects. Based to the aforementioned, this study has three goals: 1. to determine the prevalence and the epidemiologic characteristics of ACD in a population of clinical stable COPD patients 2. to investigate whether the levels of serum inflammatory markers and of plasma erythropoietin differ between COPD patients with ACD and without ACD 3. to determine potential differences regarding the aerobic exercise capacity between these two groups, using the cardiopulmonary exercise testing (CPET).
The aim of the study is to evaluate the effect of erdosteine, compared to placebo, on exacerbation rate over a 12-month treatment period in patients with moderate-to-severe COPD. Moreover, the effects of erdosteine on pulmonary function parameters, clinical symptoms and quality of life, and the long-term safety of the drug will be assessed.
This is a pilot randomized controlled trial of feasibililty and prelimnary effects of a 12 week tai chi intervention vs. usual care in patients with chronic obstructive pulmonary disease
Introduction: The prevalence of overlap between Chronic Obstructive Pulmonary Disease (COPD) and Obstructive Sleep Apnea Syndrome (OSAS) is around 10%. This overlap syndrome is an important issue because is related to nocturnal desaturation and its complications. The use of portable monitoring devices (PM) for the diagnosis of OSAS was recently accepted as an alternative to full-night polysomnography (PSG). However, there are not studies evaluating the PM recording in COPD patients to detect or exclude OSAS. Objective: To evaluate if a PM (Stardust®, Respironics, Inc, USA) could accurately measure the apnea-hypopnea index (AHI) in COPD patients with a suspicion of OSAS.
The primary objective is to evaluate the efficacy of AZD9668 compared with placebo in symptomatic COPD patients by assessing the effects on lung function and symptoms of COPD
Trial will include 40 subjects and consists of 3 visits: Screening, Treatment and Follow up. A euglycemic clamp procedure and Technosphere®/Insulin (T/I) administration will occur at Visit 2 for both COPD and non COPD subjects.
A randomised controlled trial will be performed to evaluate the effects of lung volume reduction surgery (LVRS) in patients with COPD on systemic inflammation, oxidative stress, endothelial function, arterial stiffness and blood pressure. We hypothesize that LVRS will lead to a reduction of systemic inflammation, oxidative stress, arterial stiffness and blood pressure and to improved endothelial function. For this purpose 30 patients with severe/very severe COPD (GOLD III-IV) and pulmonary emphysema who are to undergo LVRS will be randomised to one of two groups: group 1 receiving immediate LVRS and group 2 receiving LVRS after a delay of 3 months. Measures of systemic inflammation, oxidative stress, endothelial function, arterial stiffness and blood pressure will be measured at baseline and 3 months after surgery and no surgery, respectively (group 2 receiving surgery only after a delay of 3 months will serve as control group) to investigate the effects of LVRS on the described outcomes.
The purpose of this study is to evaluate if supplemental oxygen during air travel can be reliably titrated using a Hypoxia-altitude simulation test (HAST). Also, the effect of oxygen supplementation given with the various oxygen equipment allowed for air travel is studied.
The purpose of this study is to investigate the safety, tolerability, pharmacokinetics and pharmacodynamics of inhaled AZD9164 following administration of multiple ascending doses in healthy male and female subjects and COPD patients.
COPD patients often have a wide range of physical (e.g., dyspnea, fatigue, pain) and psychological (e.g., depression, anxiety) symptoms and various other debilitating conditions that cause considerable suffering for the individual. Unfortunately, many of the symptoms and health problems in patients with COPD are unrecognized and untreated. Due to the irreversible nature of COPD, the aim is not to cure the disease, but to reduce symptoms and improve quality of life. Therefore, the purpose of this project is to investigate the existence and nature of symptom clusters over time in patients with COPD and their effects on patient outcomes. Since this study aims to identify possible new subgroups of patients with COPD defined by the clustering of certain symptoms, the study also aims to investigate the relationship between the clinical presentation and certain immunologic and genetic factors.
