Steroid dependent asthma (SDA); Its variable presentation

SDA (Steroid dependent asthma) is associated with a variable clinical and laboratory picture. Despite treatment with high dosages of oral and inhaled steroids patients remain symptomatic but generally stable. Airway obstruction and airway inflammation persist as reflected in sputum neutrophilia in most patients and significant (>2%) sputum eosinophilia in a majority of these patients.
