Filter by:Systemic inflammation is present in chronic obstructive pulmonary disease (COPD), which has been linked to cardiovascular morbidity and mortality. We determined the effects of oral and inhaled corticosteroids on serum markers of inflammation in patients with stable COPD.
The aims of this study are to investigate the association between sputum and plasma levels of nociceptin and substance P with cough severity and airway hyperreactivity in patients with asthma, COPD and chronic cough.
The role of antibiotic therapy in patients with COPD remains controversial. While the outcome of several clinical trials is in favour of antibiotics, the quality of these studies in insufficient. In this study the efficacy of doxycycline is compared to placebo. All concommitant treatment (steroids, bronchodilator therapy, physiotherapy) is standardized. The investigators hypothesize that patients with an acute exacerbations will have a better outcome when treated with antibiotics.
Short term efficacy of pulmonary rehabilitation for improving functional capacity and quality of life of chronic obstructive respiratory disease (COPD) patient is well known. However, there is an important gap between the scientific knowledge and the clinical use of pulmonary rehabilitation since a a very small number of patients benefit from this therapeutic intervention. We estimate that less than 1% of the 750 000 canadians suffering from COPD have access to a pulmonary rehabilitation program. We want to study the efficacy of a home-based rehabilitation program as a way to facilitate the access to rehabilitation.
Women with chronic lung disease characterised by chronic cough report urinary incontinence. Recently there have been reports of increased urinary incontinence in girls and women with cystic fibrosis. While coughing is a known risk factor for stress incontinence, other risk factors and causes are poorly understood in this population. Treatment of incontinence for patients with chronic lung disease is also poorly addressed, adding to the burden of disease for women with chronic lung disease, carers and the health system. This project will estimate the prevalence of women with CF and COPD compared to healthy age matched controls and will evaluate the effect of a specific treatment and management program for these patients. The results will be disseminated to respiratory health professionals. We hypothesise that women with chronic cough will have a higher incidence of urinary incontinence than healthy controls and that a specific treatment program will result in alleviation of the problems and improved quality of life.
This randomized, double-blind, placebo-controlled trial assessed the efficacy of montelukast in the treatment of adults ≥50 years of age with persistent asthma and/or COPD. Primary outcomes included forced expiratory volume in one-second (FEV1) and daytime asthma symptoms scores. Nocturnal symptoms, asthma control, health-related quality of life, peak flow measurements, and health care utilization were also assessed as secondary outcomes. Participants were recruited from the Kaiser Permanente Northwest member population. One hundred forty-nine subjects were randomized to treatment with montelukast (10 mg per day) or placebo, and were followed for a six-week period. No differences in lung function measures, health-related quality of life, health care utilization, and asthma symptom scores were observed; however, the montelukast group had slightly improved asthma control scores compared to the placebo group.
A parallell group study comparing the effect of an education program with an education and training program for patients with COPD. 30 participants in each group. Participants self-select which group they wanted to be in. Main outcome is SGRQ (a HQoL for patients with COPD).
We intend to use repetitive magnetic stimulation to the quadriceps muscle to try to improve strength and improve the metabolic function of the muscle.
Neutrophil involvement in the development of COPD by smokers is well recognised. However not all smokers develop overt lung disease. We have previously shown that uptake of FDG is related to neutrophil activity and can be measured by PET and that uptake is greater in COPD patients than normal subjects. We have also shown that FDG-PET shows inflammatory changes in asymptomatic smokers after cigarette smoking. We plan to investigate the attenuation of this inflammation by steroid tablets and whether FDG PET can demonstrate this. We also wish to establish if similar changes are demonstrated after smoking by COPD patients.
In this randomised, cross-over, controlled study, a total of 84 subjects will be included: 12 healthy non-smoking volunteers; 12 current smokers; 30 patients with mild steroid-naïve asthma; and 30 patients with mild-moderate COPD. Each subject will have 1 screening visit (if necessary) and 2 study visits. At visits 2 and 3 the effects of adenosine 5'-triphosphate (ATP) or adenosine 5'-monophosphate (AMP) challenge, given in a random order, will be tested.
