Celery--cause of severe anaphylactic shock.

BACKGROUND: We present a case of anaphylactic shock induced by celery ingestion in a 28-year old woman with pollinosis during allergen (50% birch, 50% grass) immunotherapy. CASE REPORT: A female patient, aged 28 was admitted to the clinic due to a serious anaphylactic reaction. The event took place 15 min after ingesting fresh celery. She recovered after routine treatment with adrenaline, corticosteroids and antazoline. CONCLUSIONS: Our case shows the possibility of simultaneous occurrence of hypersensitivity to inhaled allergens and food. In such cases, it is considered part of cross-reactivity We discuss the importance of cross- reactivity associated with sensitization to pollen and vegetable foods.
