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 0birch, 50 0grass) 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.
