Immune Status and Disease Control of Inflammatory Airway Diseases

The goal of this study is to learn how the body's immune system affects disease control in people with different airway inflammatory diseases.We want to understand: 1.Whether specific immune cell patterns in the blood are linked to how severe the disease is or how well it is controlled. Participants will: 1. Answer questions about their health and symptoms. 2. Give blood samples 3. Have lung function tests and other standard check-ups. 4. share sleep study results. We will compare people with airway diseases to healthy volunteers to see how their immune systems differ.
