Progression of Airway Obstruction in Childhood Asthma
In Brief
An observational study for Asthma. Completed, enrolled 55 participants across 1 site.
Detailed Summary
Distinct patterns of loss in pulmonary function were identified in children with mild to moderate asthma participating in a 10-year observation period during the NHLBI Childhood Asthma Management Program. This loss in pulmonary function is likely related to ongoing inflammation unresponsive to current therapy. This study will measure indicators of airway inflammation which are associated with structural and physiologic changes in the lung and provide insight into mechanisms of asthma progression in adolescence and early adulthood.
