Canadian Consortium on Airway Mucus Occlusions in Asthma, COPD and Chronic Cough

Chronic lung diseases affect one in five Canadians, causing symptoms such as cough, breathlessness, and wheeze. Despite advancements in medical care, these conditions not only impact individuals and their close circles but also present substantial clinical and economic challenges at a national level. This grant is dedicated to addressing three prevalent lung diseases: asthma, chronic obstructive pulmonary disease (COPD), and chronic cough. An alliance of clinicians, scientists, knowledge users, and patient partners from across Canada have come together to establish the Canadian Consortium for Understanding the Role of Airway Mucus Occlusions in Asthma, COPD, and Chronic Cough - "CANMuc." Mucus plays a pivotal role in the symptoms and severity of lung diseases, but its clinical assessment has been challenging. Fortunately, recent medical advances, particularly chest computed tomography (CT), facilitate visualizing and quantifying mucus in patients with lung diseases. Our goal is to initially assess mucus plugging in a diverse group of Canadians without lung disease and then compare these findings to those with asthma, COPD, and chronic cough. The investigators will recruit 100 healthy volunteers for comprehensive clinical and research evaluations, including sputum analyses, breathing tests, quality of life assessments, cough monitoring, and CT scans. In addition, testing will be conducted twice, two years apart, in 240 adult and 50 pediatric participants. This approach will en…
