Study seeks to predict who benefits from steroid cough treatment
NCT ID NCT05888350
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether three simple measurements—blood eosinophils, FeNO (a breath test), and total IgE—can predict how well patients with chronic cough respond to inhaled corticosteroids. Over 500 adults with a cough lasting 8 weeks or more participated. The goal was to help doctors choose the right treatment without unnecessary steroid use.
