Evaluation of Reactive Oxygen Metabolites in the Value of COPD

COPD(Chronic Obstructive Pulmonary Disease)

This study through the long-term observation followed up for 2 years to find the change of the COPD patients blood ROMs, systematically evaluate the relationship between ROMs and the severity of COPD. Evaluate the differences of prognosis between the different oxidative stress level (according to the level of ROMs are divided into higher and normal phenotype). Explore the new oxidative stress evaluation index ROMs application value in COPD.

Summer-Winter Variability in the Level of Physical Activity in Daily Life in Brazilian and Belgian...

Pulmonary DiseaseChronic Obstructive

Up to this moment, the majority of studies assessing the level of physical activity in daily life in patients with COPD are limited to a cross-sectional design, which does not take into account natural variation of physical activity in daily life due to differences in climatic conditions faced throughout the year. Preliminary evidences suggest that patients with COPD have different physical activity levels according to the seasons of the year. However, the limited current evidences do not allow us to know the magnitude of differences in the level of daily physical activity in patients with COPD when taking into account climatic changes resulting from different seasons of the year in cities and countries with contrasting climatic conditions. This gap observed in the literature does not allow us at this moment to know whether we should or not consider the season of the year as one of the main causes of variability while assessing physical activity in daily life in patients with COPD. The present project proposes to investigate the hypothesis that patients with COPD who live in a place with less marked decrease in temperature between summer and winter (Londrina, Brazil) have less variability in the level of physical activity in daily life through the year in comparison to patients who live in a place with more marked climatic variability during these seasons (Leuven, Belgium).

Cognitive Status in Chronic Obstructive Pulmonary Disease's Patients

Chronic Obstructive Pulmonary Disease

Chronic obstructive pulmonary disease (COPD) is a chronic condition involving an impairment in functionality and in the execution of activities of daily life. The hypothesis of this study is to examine the relationship between cognitive status and clinical profile (respiratory, sleep quality, nutritional status) in patients with chronic obstructive pulmonary disease in two different moments: exacerbation or stable situation.

Towards Restoring the Physiological Inhibition of Airway Narrowing in Asthma

AsthmaChronic Obstructive Pulmonary Disease

Asthma and COPD are characterized by airway narrowing. The most potent, physiological mechanism leading to bronchodilation is taking a deep inspiration. This protects healthy subjects against bronchoconstrictive stimuli, and reverses pre-existing bronchoconstriction. However, the deep breath-induced bronchoprotection and -bronchodilation is impaired in asthma. We questioned whether this is specific for asthma (in comparison to COPD), and whether this is associated with bronchial inflammation and -remodelling. The study is a two-groups comparison, of physiological and pathological disease markers, obtained by methacholine challenges, monitoring airways resistance, and by taking bronchial biopsies.

Feasibility and Outcomes of Older Patients Hospitalization

Community-Acquired PneumoniaExacerbation of Chronic Heart Failure2 more

Hospitalization is a traumatic event for the patient and his family at any age nevertheless in the older age. One of its consequences is the difficulty to resume previous activity of daily living especially in older (over 75 years) patients. Sub acute completes the acute phase of the hospitalization and its main purpose is to improve the patient's functional status and quality of life. There are not enough clinical trails to proof this assumption. The purpose of our study is to compare the outcome of acute and sub-acute hospitalization programs by a randomized controlled prospective intervention study. Outcome measures will comprise activity of daily living, functional status, re-hospitalization and utilization of medical services following the hospitalization.Study hypothesis is that sub-acute hospitalization will improve outcomes and will cost less.

The Microcirculatory Characteristics of the Heart and Lung Meridians: A Study of COPD Patients and...

Chronic Obstructive Pulmonary Disease

Although some important progresses were made in the field of the meridian research, no breakthroughs have been achieved. Besides,there are some problems in meridian researches. The majority of the existing studies involve lots of subjective assessments for meridian phenomena. In addition, few studies have investigated the site specificity between two specific meridians.Therefore, this study is designed to detect the microcirculatory characteristics of meridian phenomena by using an objective assessment tool and investigate the site specificity for the meridian-visceral association and surface-surface association between two specific meridians.

Role of Pseudomonas Aeruginosa Biofilms in Exacerbations in Patients With Bronchiectasis With and...

BronchiectasisMicrobial Colonization2 more

Exacerbations, in particular during chronic Pseudomonas aeruginosa (PA) infection, are very important in the prognosis of patients with non-cystic fibrosis bronchiectasis (BE). In Cystic Fibrosis patients, PA biofilms are associated with chronic respiratory infections and are the primary cause of their increased morbidity and mortality. However, the presence and role in exacerbations of PA biofilms, microbiome dysbiosis and inflammatory biomarkers has not been studied in depth in BE patients. Our aim is to determine the association between PA chronic infection and its biofilms with the number of exacerbations in the next year (primary outcome), time until next exacerbation, quality of life, FEV1 and inflammatory biomarkers (secondary outcomes) in BE patients with or without chronic obstructive pulmonary disease (COPD). The investigators will include and follow up during 12 months post study inclusion, 48 patients with BE and 48 with BE-COPD, with a positive sputum culture of PA. During stability and follow up (and in each exacerbation) The investigators will collect 4 sputum, 4 serum samples, perform spirometry, and quality of life tests every three months. For the biomarkers subproject, 4 additional serum samples will be collected at: exacerbation, 3-5 days after treatment, at 30 days and three months post-exacerbation. Biomarkers will be measured by commercial kits and Luminex. The investigators will quantify PA colony forming units (CFU)/mL, their resistance pattern, their mutation frequency and isolate mucoid and non-mucoid colonies. In each sputum, the investigators will analyze by Confocal Laser Scanning Microscopy (CLSM) and Fluorescent in situ Hybridizatrion (FISH) PA biofilms, their size, bacterial density and their in situ growth rate. Specific serum antibodies against PA will be determined through Crossed Immunoelectrophoresis. In addition, the investigators will indentify potential respiratory microbiome and gene expression patterns predictive for exacerbations, or with a protective role against chronic PA infection, as well as their association with biofilms. Microbiome analysis will be performed through the Illumina Miseq platform. Finally, the investigators will explore the antimicrobial activity of novel combinations of antibiotics against PA, both in in vitro planktonic cultures and in a biofilm model, and will include testing of antibiotic-containing alginate nanoparticles.

Effect of BDP/Formoterol/G on Cough Efficacy in Moderate to Severe COPD Patients (EFFICACE)

COPDChronic Obstructive Pulmonary Disease

This prospective, single centre, 8 weeks, open-label study is designed to evaluate in real-life the effect of triple Beclometasone/Formoterol/Glycopyrronium (BDP/F/G) therapy on cough efficacy, assessed by cough peak flow (CPF), after 8 weeks' treatment in patients with moderate to severe COPD. The study's hypothesis is that in symptomatic moderate to severe COPD patients the administration of fixed dose combination BDP/F/G, by reducing lung hyperinflation (LH) and targeting small airways, may accordingly improve the cough efficacy. The increase in cough efficacy might in turn positively influence the quality of life of patients and underlie the prevention of acute exacerbations of COPD.
