Allergy to jerusalem artichoke due to immediate IgE reaction to Bet v1-like allergen.

摘要

Jerusalem artichoke (JA) {Helianthus tuberosus), also called topi-nambur, is a vegetable from the Asteraceae family. Its tuberous rhizomes can be eaten raw or cooked, and it underwent a resurgence of interest in Europe during the end of the 20th century. We report the first case, to our knowledge, of IgE-mediated food allergy to JA due to a Bet vl-like allergen (e-Fig 1). A 40-year-old woman presented with springtime rhinitis for the preceding 4 years. She reported an oral allergy syndrome (OAS) to apples, cherries, peaches, hazelnuts, and raw JA. Reactions to raw JA were more severe than with other fruits (OAS, laryngeal edema,' and face swelling). Cooked JA was tolerated.
