Filter by:Chronic obstructive pulmonary disease is characterized as inflammatory airway with not fully reversible airflow limitation.Combination treatment with inhaled corticosteroid (ICS) and long-acting β2 agonists (LABA)attains an improved control of symptoms and lung function, that are superior to those associated with either drug alone. However, the treatment efficacy between high and medium dose of inhaled corticosteroid in combination of LABA is still unknown. The aim of the current study is to investigate the treatment efficacy with high and medium dose of fluticasone in combination with salmeterol in COPD patients.
No studies have been done to examine whether patients with obstructive lung disease and obesity are more comfortable on some ventilator settings than on others. The purpose of the current study is to examine this question systematically.
The research project CHAIN (COPD Assessment History in Spain): "A Multidimensional Study on the Evolution of Chronic Obstructive Pulmonary Disease (COPD)is a multicentre, observational study conducted in several areas of Spain aimed to better define COPD natural history and its phenotypes
Parallel, randomized and controlled clinical trial to evaluate the effect of 12 months of noninvasive mechanical ventilation versus conventional treatment in hypercapnic patients with stable COPD. Main objective: To evaluate the effect of 12 months of noninvasive ventilation on c-reactive protein concentration and daily physical activity in hypercapnic patients with stable COPD. Secondary objectives: To compare the plasmatic concentration of other inflammatory biomarkers between COPD patients with conventional treatment and wich noninvasive ventilation. To determine the response of breathlessness, health-related quality of life and lung function to noninvasive ventilation. To identify the COPD patients with a higher gasometric and clinic response to noninvasive ventilation.
This study is looking at whether there is a difference in outcomes using two different types of breathing support in those patients who have chronic respiratory failure (patients who under-breathe). There is little data to demonstrate which mode of ventilation is better in terms of physiological outcomes and outcome data relating to patient symptoms. We hypothesize that one type of breathing support: pressure support ventilation would be more comfortable for patients as it more closely matches a patient's own respiratory pattern and and so leads to improved adherence and consequent improvement in quality of life. Patients with respiratory failure will be randomly assigned to receive either pressure support ventilation or pressure control ventilation for the first 6 weeks and then cross-over to receive the mode not previously used for a further 6 weeks. They will have baseline data recorded and then be followed up after each 6 week block.
This randomized controlled trial will assess the effect of adding intensive physical activity counseling to an outpatient pulmonary rehabilitation program. Counseling including real-time feedback on daily activities from an activity monitor will be offered to improve participation in physical activities in daily life during and after an outpatient pulmonary rehabilitation program.
Looking at the use of home telehealth equipment and it's place in self management and education in patients who suffer moderate to severe Chronic Obstructive Pulmonary Disease (COPD). The patients in this group would be those patients who traditionally suffer from emphysema, and/or chronic bronchitis.
A biobank of Serum, plasma, DNA samples together with clinical information including specific questionnaires, complete pulmonary function and chest CT-scan, is prospectively collected in patients seen at the investigators' clinical service. The objective is to study candidate gene pathways in COPD and or lung cancer and to associate them with the clinical characteristics and phenotypes of COPD/emphysema and lung cancer. In subgroups of well characterised patients, other biological materials are also collected (lung tissue biopsies, peripheral blood mononuclear cells).
COPD is ranked number 3 by the WHO list of important diseases worldwide and is the only disease with increasing mortality. The pathogenesis of cigarette smoke-induced COPD is obscure, therefore more insight is needed to design effective anti-inflammatory agents. Recently it has become clear that cigarette smoke-induced inflammation is not only present in the lungs but also in the blood, and that this systemic inflammation has important consequences for the clinical expression of COPD. The investigators hypothesize that healthy individuals who are susceptible to cigarette smoking demonstrate a higher and aberrant systemic inflammatory response to cigarette smoke. This susceptibility is caused by heterogeneous factors and is associated with various polymorphic genes that interact with each other and with the environment. Objective: - To study systemic inflammation in individuals who are or are not susceptible to develop COPD. - To characterize the switch to chronicity of the systemic inflmmatory response in COPD - To determine whether the type and severity of the systemic inflammation contributes to the clinical outcome of COPD - To compare between subjects who are or are not susceptible to develop COPD in peripheral blood, the corticosteroid responsiveness in vitro, and to unravel underlying mechanisms. - To study the role of candidate genes that may play a role in the development of fixed airway obstruction, and to identify clues for patient's responsiveness to specific drugs - To develop new biological and clinical markers for the early diagnosis and monitoring of COPD - To define possible mediators involved in the early induction of COPD in susceptible smokers, and to define new drug targets
The purpose of this study is: - To define The differences of bio-chemical phenotypes in chronic airway inflammatory diseases. - To identify novel biomarkers in chronic airway inflammatory diseases as a screening, diagnostic, or monitoring marker.
