Active clinical trials for "Pulmonary Disease, Chronic Obstructive"

To evaluate the pulmonary gas exchange response to a therapeutic high dose of inhaled indacaterol (300 mcg) in 20 outpatients with stable symptomatic COPD B and D GOLD 2011 groups. Measurements on a single day before and after 60 and 120 minutes of indacaterol will include arterial PO2, PaCO2 and pH. AaPO2; SaO2 (by pulse oximetry) and oxygen and carbon dioxide in exhaled breath, systemic arterial pressure and heart rate will also be measured/calculated. Cardiac output will be directly measured by bio-impedance.

Chronic Obstructive Pulmonary Disease (COPD) is a kind of chronic bronchitis or emphysema with characteristics of long-term poor airflow, resulting in chronic pulmonary heart disease, chronic respiratory failure or even death. Anatomically, the pulmonary bronchus structures in COPD patients are damaged and cannot be repaired by recent clinical treatment so far. This study intends to carry out an open, single-armed, phase I/II clinical trial to investigate whether bronchial basal cells can regenerate damaged lung tissue. During the treatment, bronchial basal cells will be isolated from patients' own bronchi and expanded in vitro. After careful characterization, cultured cells will be transplanted autologously into the lesion by fiberoptic bronchoscopy. The safety and efficacy of the treatment will be monitored by measuring the key clinical indicators.

This phase II single centre, double blind, placebo-controlled, randomised trial aims to test the hypothesis that intravenous iron improves exercise performance in Chronic Obstructive Pulmonary Disease (COPD) as measured by constant rate cycle ergometry.

A phase 3 study to evaluate efficacy and safety of HCP1202

This a single center non-randomised non-sham controlled intervention study evaluating the effectiveness and safety of endoscopic lung volume reduction by endobronchial valves

Chronic Obstructive Pulmonary Disease (COPD) is a chronic respiratory disease characterized by persistent airflow limitation. The patients are suffering dyspnea year by year, resulting in the decreased exercise tolerance and quality of life. Patients with COPD often have both inspiratory muscles and expiratory muscle dysfunction. Respiratory muscle training was one of the widely used pulmonary rehabilitation method in COPD patients. Respiratory muscle training include inspiratory training ,expiratory training and concurrent inspiratory and expiratory muscle training . Both of the training methods are effective. However, the effects of these different types of respiratory muscle training method on the respiratory physiology and neural respiratory drive of COPD are still unclear. Therefore, the purpose of this study was to investigate the different effects of these respiratory muscle training methods on respiratory mechanics and central drive in COPD patients. Besides,the effect of the different respiratory muscle training methods was compared between patients with and without respiratory muscle weakness.

Assessment of the effect and safety of noninvasive positive pressure ventilation for severe stable chronic obstructive pulmonary disease

Chronic obstructive pulmonary disease (COPD) is characterized by a poorly reversible airway obstruction and consequent systemic manifestations. Its high prevalence and high number of diagnosed patients has become a challenge for health services due to the costs of diagnosis and treatment of these patients. Positive pressure and aerosol therapy are preferred therapies for the management of COPD symptoms, but their effects when associated are poorly studied. The objective of this study is to compare the effects of different positive pressure strategies associated with aerosol therapy through Pulmonary Scintigraphy and Electrical Impedance Tomography (EIT) in patients with COPD in the intercrise period. This is a randomized, crossover, blinded and allocated crossover type clinical trial in which patients with moderate to severe COPD will be allocated to three intervention groups with different strategies for positive pressure associated with aerosol therapy: control group 1 nebulization), group 2 nebulization with EPAP valve and group 3 nebulization with NIV bi-level pressure mode. The radioaerosol deposition pattern will be evaluated through Pulmonary Scintigraphy and regional pulmonary ventilation through EIT.

Although non-invasive ventilation (NIV) usage has increased significantly over time in COPD exacerbation, a great percentage of patients (~30%) present contraindications to NIV or cannot tolerate it. Nasal high flow (NHF) has been introduced for the management of hypoxemic respiratory failure in adults with favorable effects on ventilation and respiratory mechanics. The above mentioned NHF positive effects has been observed also in stable COPD patients with or without chronic hypercapnia. In this study, the investigators hypothesize that NHF is not inferior to NIV for respiratory support in patients with COPD exacerbation and acute or acute on chronic hypercapnic respiratory failure.

Introduction In order to guarantee chronic patients & elderly a high quality service from health care organizations in the coming decades, new technologies have been implemented to treat patients from a distance. There is still a need for more studies on the efficacy and cost-effectiveness of tele-rehabilitation (TR) and its long-term effects needs also to be determined. To guarantee individuals with chronic obstructive pulmonary diseases (COPD) a high quality service from health care organizations in the coming decades and economically save the national health systems for an expensive bill for the treatment of COPD, new actions plans has to be taken into use. Hereby, more patients can be treated with less human resources while still sustaining or even improving today's services. The importance of such welfare action plans has to maintain a high quality of service that individuals with COPD are willing to accept. Here, TR seems to be a good welfare action plans. Despite proof of improved cost-effectiveness, no studies support the benefits of TR in COPD patient with respect to adherence, security, treatment efficacy and improved quality of life. Aim To assess and compare the feasibility and effect of a tele-rehabilitation program with a new and innovative TR platform (NITRP) compared to standard treatment with respect to exercise capacity, quality of life and activities of daily living in patients with COPD. Method and material The study is a prospective randomized controlled trial comparing the effects of a follow-up tele-rehabilitation program and conventional follow-up rehabilitation in patients with severe COPD. 54 patients fulfilling the inclusion criteria will be randomized in two groups to either an 8 week follow-up tele-rehabilitation program or to standard follow up after rehabilitation. Participants will be tested at baseline, after 8 weeks and 6 months after cessation of the training programs. In the intervention group, a real- and a virtual physiotherapist agent will facilitate the rehabilitation. Ethical considerations This study will not pose any risk to the patient as compared to current practice. Participation is voluntary and the patient may at any time withdraw from the study without consequences for future care or treatment. The questionnaires and the test methods used are clinically recognized instruments. Signed informed consent will be obtained from the all participants after verbal and written information and before the study starts. The study will not be initiated before approval from the Ethics Committee and the Data Protection Agency has been obtained. The study will follow the general research ethical rules as expressed in the Helsinki Declaration II.
