Food-dependent exercise-induced anaphylaxis.

This article describes four cases of exercise-induced anaphylaxis occurring only in temporal relationship to the ingestion of food. One individual developed anaphylaxis if exercise followed the ingestion of any food within 2 hr. Three other individuals had symptoms only if celery was ingested in relation to exercise. Skin reactivity to fresh celery extracts was demonstrated in all three individuals. The episodes were prevented by avoidance of food ingestion in relation to exercise. This syndrome appears to be a variant of exercised-induced anaphylaxis.
