Filter by:Patients with chronic hypercapnic respiratory failure can be successfully treated with home nocturnal non-invasive ventilation. Bi-level pressure support ventilators are at present the most frequently used ventilators for long term home ventilation. A recently commercialized bi-level ventilator offers the feature of automatically adjusting pressure support on the basis of a pre-determined ideal effective ventilation. Because this option may induce important swings in pressure support, and thus patient discomfort, and maybe increase leaks, we chose to analyse the impact of average volume assured pressure support (AVAPS) on patient comfort, subjective and objective quality of sleep and efficacy of ventilatory support.
The role of HGF and KGF in COPD is poorly known. Plantier et al found that cultured fibroblasts harvested from patients with emphysema produced less HGF (but similar amounts of KGF) than controls, and Bonay et al found a direct relationship between the severity of airflow obstruction and HGF mRNA content in lung samples of smokers. These two studies suggest, therefore, that the pulmonary regulation of HGF may be abnormal in patients with COPD. However, both HGF and KGF can also be released by extra-pulmonary organs, thus having the potential to act systemically. Given the current clinical relevance attributed to the systemic effects of COPD, in this study we compared the levels of HGF and KGF in the pulmonary (bronchoalveolar lavage (BAL) fluid) and systemic compartment (circulating blood) of smokers with and without COPD and never smokers.
To evaluate the 1-year efficacy and safety of the fixed combination beclometasone/formoterol pMDI in a twice daily regimen in patients with stable severe COPD.
This trial is for men and women between the ages of 40 and 74 who have a confirmed diagnosis of emphysema. The objective of the trial is to determine the safety and effectiveness of the IBV Valve at redirecting airflow from diseased portions of the lung to healthier areas to achieve improvement in disease-related health status.
This trial is conducted in Europe, Asia and South America. A one-year clinical trial to compare the safety of inhaled human insulin to subcutaneous insulin aspart in subjects with type 1 or type 2 diabetes and chronic obstructive pulmonary disease (COPD).
Hypothesis:benefits of inspiratory muscle strenght training with Respifit S decreases symptoms, disability or handicap of patients affected by COPD. The inspiratory fraction (inspiratory capacity IC/ total lung capacity TLC)may be functionally more representative than other traditional indices.
The purpose of this study is to determine the effect of preventing hyperglycaemia in patients admitted to hospital with acute exacerbations of chronic pulmonary disease.
The study is a randomized trial of a cardiopulmonary self-management intervention to improve functional capacity, health-related quality of life, and to reduce health care utilization. Two hundred (100 in each group) will be recruited from VA Puget Sound Health Care System over four years. Outcomes will be measured at three points: at entry, at the end of the 6 month intervention, and 12 months after entry. Change in functional capacity at the end of the intervention program is the primary outcome.
To assess the effect of a single dose of TrIP on pulmonary function in patients with COPD
This study, a new immunomodulatory therapy of COPD with vasoactive intestinal peptide (VIP) was evaluated. Based on preliminary unpublished clinical and experimental results, the course of disease under VIP treatment and the molecular mechanisms involved were assessed. 34 patients with severe COPD were treated either with VIP inhalation in addition to conventional therapy or inhalation of placebo plus conventional therapy for a period of 3 months. The trial was conducted as a double blind, comparative study with two parallel groups.
