Filter by:Non-invasive inert gas rebreathing (IGR) based on the Fick Principle showed promising results in the determination of pulmonary blood flow (PBF). The volume of the rebreathing bag (Vbag) is proposed by the system, however, elderly patients or those suffering from high grade pulmonary diseases might be unable to entirely rebreathe this volume and therefore fail to completely mix the test gases. The aim of our study is to evaluate the effect of adapting Vbag on the reproducibility of IGR measurements in patients with obstruction (group A), restriction (group B) and pulmonary healthy controls (group C).
The purpose of this research study is to determine whether exhaled nitric oxide (FeNO) goes up during an acute exacerbation of Chronic Obstructive Pulmonary Disease (AECOPD) and whether the level of exhaled nitric oxide returns to normal in the weeks after an exacerbation.
To investigate whether Budesonide/Formoterol (Symbicort ®) therapy can improve heart function at rest by decreasing lung hyperinflation in patients with COPD (Chronic Obstructive Pulmonary Disease).
The aim of this study is to show if the six-minute stepper test (ST6) is a sensible marker of exercise tolerance evolution during a pulmonary rehabilitation program in people with all stages of severity of Chronic Obstructive Pulmonary Disease (COPD).
An Open Label, Pilot Study Testing the Safety and Efficacy of Inhaled Treprostinil (Tyvaso®) in the Treatment of Pulmonary Hypertension (PH) Associated with Chronic Obstructive Pulmonary Disease (COPD)
This study is to evaluate if add-on treatment with inhaled NVA237 (50 µg) once daily (o.d.) via single-dose dry-powder inhaler (SDDPI) further improves lung function and health status and is well tolerated compared to placebo in symptomatic COPD patients with moderate to severe airflow limitation who are already receiving maintenance therapy with inhaled fixed-dose-combination of salmeterol/fluticasone propionate (50/500 µg) twice daily (b.i.d.) via multi-dose dry powder inhaler (MDDPI).
This is a First in Human study to assess the safety and tolerability of AZD7624, following inhaled administration of single ascending doses in healthy male volunteers and female volunteers of non-child bearing potential. Pharmacokinetics (what the body does to the drug) and pharmacodynamic (what the drug does to the body) parameters will be also assessed as secondary objectives.
The objective of the study is to assess patient's perception with stable state COPD on symptom variability and to describe how symptom variability impacts daily quality of life in Chinese COPD patient with moderate, severe or very severe airflow limitation from tier 3 hospitals in China where most of COPD patients are diagnosed and treated.
ECOS is a cross-sectional, observational, longitudinal, multicenter study enrolling 100-200 patients during a COPD exacerbation.
The objective of the project is to better understand the causes of exercise limitation, dyspnea and neurohumoral activation in patients with COPD. In particular, the investigators aim to explore the mutual interaction of neurohumoral activation and exercise limitation thereby focussing on differential effects of the peripheral muscle and the diaphragm. Eventually the findings might influence treatment modalities. If sympathetic activation contributes to exercise limitation then drugs influencing the autonomic nervous system would be a reasonable therapeutic concept. If a reduction of sympathetic activity due to an alteration of the ergoreflex can be achieved by non-invasive ventilation this would help to improve dyspnea and exercise capacity.
