Filter by:Chronic obstructive pulmonary disease (COPD) is a condition characterized by airway obstruction. Patients with COPD experience significant shortness of breath on exertion. The mechanisms responsible for shortness of breath on exertion are well understood in moderate and severe COPD, but, are poorly understood in mild COPD where symptoms appear disproportionate to the degree of airway obstruction. Mild COPD patients show an exaggerated breathing response to exercise, determined by the breathing response to carbon dioxide production (V̇E/V̇CO2). Recent work suggests that the increased V̇E/V̇CO2 during exercise in mild COPD is secondary to increased deadspace (i.e. lung regions with ventilation but no perfusion) and/or ventilation/perfusion (V̇A/Q) inequality (poor matching of ventilation to perfusion). Researchers have proposed that the increased deadspace or V̇A/Q inequality is secondary to pulmonary vascular dysfunction and hypoperfusion of the pulmonary capillaries. Recently, we have shown that inhaled nitric oxide, a potent dilator of pulmonary vasculature, reduces shortness of breath and V̇E/V̇CO2, and improves exercise capacity in mild COPD. This preliminary finding suggests that pulmonary vascular dysfunction is an important contributor to exercise intolerance in mild COPD. Here, we aim to test whether sildenafil, an oral pulmonary vasodilator, can improve exercise tolerance and shortness of breath in mild COPD.
As protocol NCT04223050. This substudy furthermore investigates the role of oxidative stress in the administration of oxygen in COPD patients.
To evaluate the safety, tolerability and pharmacokinetic characteristics of TQC3721 suspension for inhalation in single/multiple administration(s) in healthy subjects; to evaluate the safety,tolerability and efficacy TQC3721 suspension for inhalation in multiple administrations in patients with Chronic Obstructive Pulmonary Disease(COPD)and asthma.
Respiratory rehabilitation is an intervention proven to improve quality of life in those with chronic lung disease but access remains poor. The investigators will assess the feasibility and acceptability of a virtual platform for respiratory rehabilitation as an alternative to in person rehabilitation. The aim is to use the technology in those post admission with COPD where access has been even more of a challenge as during this period patients find it difficult to access an out patient program due to their frailty.
This is a prospective interventional study to determine whether the profile of volatile organic compounds (VOCs) present in exhaled air (VOLATOLOM) is reproducible in stable severe COPD (Chronic Obstructive Pulmonary Disease) patients.
Discovery of the pathogenesis and targets in the progression of early chronic obstructive pulmonary disease
The CATALINA study is a prospective cohort study embedded within CICERO (Collaboration In COPD ExaceRbatiOns, a European Respiratory Society supported Clinical Research Collaboration), designed to collect standardised, longitudinal clinical data and biological samples in 20 centres across Europe.
As a result of the study, inspiratory muscle strength, posture and physical performance evaluations of individuals with Chronic Obstructive Pulmonary Disease will be made, suggestions will be made to help individual postural smoothness and improve physical performance.
This project has focus on patients in palliation testing a digital platform TelePal.dk.
In the literature, studies evaluating respiratory muscle function, diaphragm thickness and health-related physical fitness parameters together are insufficient in individuals with chronic obstructive pulmonary disease. In the thesis study, it is thought that the respiratory muscle function, diaphragm thickness, health-related physical fitness parameters, physical activity and lung functions of individuals with chronic obstructive pulmonary disease can be evaluated together to contribute to the literature. The aim of this study is to evaluate diaphragm thickness, respiratory muscle strength, endurance, body composition, aerobic exercise capacity, upper and lower extremity muscle strength and endurance, grip strength, flexibility in individuals with chronic obstructive pulmonary disease and compare them with the healthy group.
