Abstract

Severe asthma as manifest by the continuous high dose of inhaled corticosteroids, or oral corticosteroids for >50% of the previous year, remains a huge problem despite significant advances in pharmacotherapy. As many as 5-10% of all asthma hospitalizations result in ICU admission, with an overall mortality rate of 0.4%. Hallmarks of severe asthma include polymorphisms in the beta-2 receptor, arginine substitutions at position 16 (Arg/Arg), a female gender, diminished perception of dyspnea, and steroid resistance. A protocol for evaluation and immediate therapy is suggested based on a review of the literature.
