Lessons about food anaphylaxis

摘要

Exercise-induced anaphylaxis (EIA) and its subtype food-dependent (FD)-EIA are uncommon and easily missed forms of physical allergy. The latter is triggered by exercise following the ingestion of specific food products. Treatment is identical to that for IgE-mediated allergic reactions. The disease is potentially fatal. In this case, 30-year-old woman was seen in the allergy clinic at the request of her general practitioner. She reported an episode when she had gone to a local park to exercise after dinner. Shortly thereafter, she collapsed with rash, lip swelling, and breathing difficulties. Upon admission to hospital, she was found to be hypotensive and required fluid resuscitation, systemic corticosteroids and adrenaline. She made a full and uneventful recovery. On the basis of the clinical story and specific allergy markers, her presentation was attributed to FD-EIA.
