Case report—wheat-dependent exercise-induced anaphylaxis in a patient with chronic spontaneous urticaria: A diagnostic challenge

Wheat-dependent exercise-induced anaphylaxis is a rare but severe form of anaphylaxis that occurs after consuming wheat products and engaging in physical activity. A case study of a 30-year-old woman suffering from chronic urticaria for the last 5 years highlights the difficulty in diagnosing this condition, as specific triggers were not identified. A diagnostic study called MADx revealed a positive analysis for omega-5-gliadin, leading to a diagnosis of wheat-dependent exercise-induced anaphylaxis. Delayed diagnosis is a common issue, and it can be challenging to distinguish wheat-dependent exercise-induced anaphylaxis from other conditions with similar symptoms. The treatment involves avoiding wheat products and always carrying an epinephrine auto-injector. When evaluating patients with similar symptoms, healthcare providers should include wheat-dependent exercise-induced anaphylaxis in their differential diagnosis. Patients should be educated about the symptoms, triggers, and management to seek immediate medical attention in an emergency.
