The Onset of Food-dependent Exercise-induced Anaphylaxis in an Elderly Patient.

The development of allergic diseases is common in the young but rare in the elderly. We encountered an elderly patient with food-dependent exercise-induced anaphylaxis (FDEIA). An 82-year-old man was rushed to the hospital for symptoms of anaphylaxis. Because the symptoms occurred after ingestion of wheat products and exercise, we made a diagnosis of FDEIA based on a high ω5-gliadin IgE level and a positive exercise test. Based on our review of the existing literature, this was the oldest patient to ever be diagnosed with FDEIA in Japan. This case suggests that physicians should keep in mind that older adults can develop FDEIA.
