Abstract
Two adolescent cases were diagnosed as exercise-induced anaphylaxis (EIA) with urticaria, dyspnea and loss of consciousness after exercise.
A thirteen year old boy had 5 episodes of generalised urticaria, dyspnea and confusion after running since 11 years of age and responded mildly to bicycle ergometer. A sixteen year old asthmatic girl had several episodes of swelling on eyelids, papular rash on extremities within 2 hours after eating and followed by generalised urticaria, dyspnea and confusion after running since 14 years of age, but didn't respond to bicycle ergometer. Both cases showed typical sympotoms of EIA in adolescent age with high serum IgE and atopic diathesis.
