Filter by:The purpose of this study was to compare dynamic inspiratory flow rates achieved by a population of Chronic Obstructive Pulmonary Disease (COPD) patients through the Breezhaler®, Ellipta® and Handihaler® dry powder inhaler (DPI) devices. No active drug or placebo were administered to patients in this study.
The study evaluates the safety and the efficacy of the addition of intravenous transplantation of donor bone marrow mesenchymal stem cells in patients with idiopathic interstitial pneumonia or connective tissue disease associated with interstitial lung disease, which have actively progressing disease with rapid loss of pulmonary function on the background of routine treatment.
The aim of the study is to assess the peripheral endothelial function in adult COPD (chronic obstructive pulmonary disease) patients and the relationship between the peripheral endothelial function and the pulmonary function.
In the patients with COPD mechanical ventilation, the bronchial dilatation is very common. However, the evaluation of the efficacy of the medical examination and other subjective indicators, such as doctors, depends on the doctor's experience; at present, there is no objective evaluation index. For patients with mechanical ventilation, the risk of cross infection can not only increase the risk of cross infection, but also increase the workload of clinical doctors and nurses. Therefore, this study proposes an objective evaluation method to evaluate the response of COPD patients to bronchial dilation. The hypothesis of this study can be used to guide the clinical medication through the test of the bronchus. If the patients with bronchial dilation test positive were used in the test, the patients were not used. In this evaluation method, the changes of airway resistance were measured by the accurate measurement of the patients with inhaled bronchial dilatation.
This is a multicenter, prospective, randomized, double-blind, placebo-controlled trial that will enroll 1028 patients with at least moderately severe COPD over a three year period and follow them at regular intervals for one year. The primary endpoint is time to first acute exacerbation. Secondary endpoints include rates and severity of COPD exacerbations, cardiovascular events, all-cause mortality, lung function, dyspnea, quality of life and metoprolol-related side effects.
Morbidity and mortality in COPD result largely of acute exacerbations.The optimization of the respiratory management represents a fundamental challenge for improving prognosis and reducing mortality. While the hospital mortality of patients treated with NIV has decreased over years, and is currently less than 10 %, mortality in patients treated with invasive ventilation remains higher than 25%. To improve the prognosis of patients with acute exacerbation of COPD requiring invasive mechanical ventilation is therefore a major challenge in terms of morbidity and mortality. Among the means available to achieve this goal, minimally invasive extracorporeal CO2 removal (ECCO2R) seems to be a very promising approach. The investigators hypothesize that the addition of minimally invasive ECCO2R is likely to limit dynamic hyperinflation in COPD patients requiring invasive mechanical ventilation for an acute exacerbation, while improving gas exchange.
Chronic obstructive pulmonary disease (COPD) is a preventable and treatable disease characterized by airflow limitation that is not fully reversible. The mainstay for treatment involves the use of inhaled medications, including short and/or long-acting bronchodilators along with inhaled corticosteroids. For inhaled medications, the choice of inhalation device is an important consideration because an inadequate technique reduces the effects of inhalation. Therefore, the development of an easy-to-use inhaler that delivers the drug to the lungs effectively, is important. This study will assess the correct use of the ELLIPTA inhaler by subjects with COPD and to assess ease of use of the ELLIPTA inhaler, as rated by those subjects determined to be using the inhaler correctly. Study will be divided into two visits i.e. Screening/Visit 1 (day 1) and Visit 2 (Day 28 +/-2) with a phone call on Day 8+/-2 days of Visit 1 to assess safety. In this multi-center, single-arm, randomised (to receive one of two versions of the ELLIPTA inhaler Ease of Use questionnaires), open-label, placebo study, only subjects who are have never used the ELLIPTA inhaler before and have an established diagnosis of COPD and receiving COPD therapy and are able to demonstrate correct use of the ELLIPTA inhaler at Visit 1 will be considered eligible to participate in this study. Approximately 252 subjects will be screened with an expectation of 208 subjects completing the study while demonstrating correct ELLIPTA inhaler use at visit 2.

Dynamic pulmonary hyperinflation (DH) and intrinsic positive end-expiratory pressure (PEEP) are well known problems in COPD patients with acute and chronic respiratory failure. Measurement of intrinsic PEEP level during both, invasive and non-invasive ventilation is of major importance since in some circumstances (e.g. during exercise or during exacerbations) it can significantly increase respiratory workload of COPD patients. Extrinsic PEEP applied during both, invasive and noninvasive ventilation is used to overcome intrinsic PEEP and therefore to avoid or reduce dynamic hyperinflation.
The main purpose of this study is to determine whether pharmacological treatment with N-acetylcysteine improves central and peripheral cardiorespiratory control and physical capacity in COPD patients with mild-to-moderate airflow obstruction.
Evaluating the diagnostic value of transbronchial lung cryobiopsy (TBLC) as well as its procedural feasibility and safety in a prospective series of 20 patients with diffuse interstitial lung diseases (DILD) who are referred for invasive histopathological diagnostics
