Filter by:Lymphoid follicles, consisting of T-and B cells, are involved in the chronic inflammatory response in COPD. Foxp3 positive regulatory T cells (Tregs) are present in these follicles and may be involved in the suppression of this chronic inflammatory response. We hypothesise that a dysfunction of Tregs underlies the development of the inflammatory response in COPD. This could be either due to a decreased presence of Tregs in COPD, or to an altered function of Tregs possibly caused by a decreased HO-1 expression and/or an altered TGFβ regulation.
Glucose control has been shown as an important and independent prognostic factor in several acute conditions in hospitalized patients, including Acute MI, stroke, cardiac surgery and in critical care units. Patients with acute exacerbation of COPD (AECOPD)and diabetes treated with insulin had a longer in-patient stay and more frequent isolation of Gram negative bacteria from sputum than those without diabetes.Hyperglycemia (>11 mmol/l) on admission predicted failure of non-invasive ventilation and infectious pulmonary complications in patients admitted to the ICU with acute respiratory failure caused by severe AECOPD. The primary goal of this study is to test the hypothesis that in AECOPD, tight glycemic control during hospital stay will improve outcome of hospitalization. The secondary goal of this study is to test new ways in controlling patients in the internal medicine ward.
This study aimed to assess airway inflammation in patients during the course of acute exacerbations of chronic obstructive pulmonary disease (AECOPD) by serial analyses of their exhaled breath condensates (EBC).
COPD is a major cause of ill health and death in Australia with 40,000 hospital admissions, and a national cost of $898,000,000 annually. The gold standard treatment of COPD is steroids for inflammation, antibiotics for infection and bronchodilators and oxygen for respiratory failure. However, associated mucus hypersecretion is responsible for much of the inflammation and infection. The use of pharmaceutical agents to assist in the early clearance of the retained mucus has been limited, primarily because of lack of demonstrated effect. There has been a recent development of interest in pursuing new therapies for improving mucociliary clearance and several studies have demonstrated that clinical outcomes can be improved when osmotic agents such as mannitol are added to standard treatments. The purpose of this study is to conduct a pilot safety study in patients with an acute exacerbation of COPD to determine if it is safe to administer inhaled mannitol for facilitating mucus clearance.
The main purpose of the study is to evaluate the effect of mannitol on the cilia's beat frequency (ciliary beat frequency) in COPD patients.
The effect of neuromuscular electrical stimulation on muscle atrophy in sedated patients on intensive care was studied. The aim of this study was to explore if electrical stimulation could prevent muscle atrophy.
This is a two-part study conducted at multiple centers, of navarixin (SCH 527123, MK-7123) in participants with moderate to severe chronic obstructive pulmonary disease (COPD). Part 1 of the study is a double-blind, placebo-controlled, randomized, rising-dose study consisting of four treatment groups enrolled in three cohorts. The duration of treatment, for each cohort, will be a 2-week run-in period, followed by a 12-week double-blind treatment period. Treatment initiation for each cohort was staggered by 4 weeks to allow for safety assessment prior to use of higher doses of navarixin. Part 2 of the study will be a double-blind, placebo-controlled, randomized, parallel group study consisting of four treatment groups enrolled as one cohort. The duration of treatment will consist of a 2-week run-in period, followed by a 12-week double-blind treatment period.

Guidelines recommend inhaled corticosteroids (ICS) for patients with moderate to severe chronic obstructive pulmonary disease (COPD). Most COPD patients are managed in primary care and receive ICS long-term and irrespective of severity. The effect of withdrawing ICS from COPD patients in primary care is unknown.This randomised double-blind placebo-controlled trial will evaluate the effect of withdrawal of inhaled corticosteroids in patients with COPD recruited from general practice. Participants will have a clinical and spirometric diagnosis of COPD and will have been prescribed inhaled steroids for the 6 months before entry to the trial. They will be randomised to taking a fixed dose steroid inhaler (Flixotide Accuhaler) or an identical placebo inhaler. Patients will be monitored using diary cards for a year with 3 monthly follow-up visits at their general practice. The primary outcome measures will be exacerbation frequency and severity. Other outcomes are time to first exacerbation, costs, health status, lung function and unscheduled care. We tested the hypothesis that withdrawal of ICS in this population would lead to an increased number of exacerbations, earlier onset of exacerbation, and a worsening of symptoms.
This study will investigate potential differences in how two puffs of salbutamol protects airway smooth muscle from contracting in people with asthma and chronic obstructive pulmonary disease (COPD).
