COMPONENT ANALYSIS OF THREE ANISAKIASIS ALLERGY CASES IN OUR DEPARTMENT].

Reactivity to an anisakis allergen component was examined in three patients with a history of an anisakiasis anaphylaxis. Case 1, a 38-year-old man, allergic symptoms appeared 0.5 hours after ingestion, and the component Ani s 1 and 3 were positive. Case 2, a 44-year-old woman, allergic symptoms appeared 4 hours after ingestion, and components Ani s 3 and 12 were positive. Case 3, a 36-year-old woman, developed allergic symptoms 7 hours after ingestion of fish and shellfish, and tested positive for Ani s 1, 4, and 12. Case 3 reacted strongly to both heated and unheated Anisakis extract, while cases 1 and 2 reacted weakly to heated Anisakis extract. The most common allergen was Ani s 12, followed by Ani s 1, when analyzed in conjunction with existing reports on 10 cases. Anisakis IgE was class 3 or higher in all cases. Analysis of 13 cases showed 2 cases sensitized to Ani s 4 and moderate or higher anaphylaxis, while Ani s 4-sensitized patients were reported to be more likely to develop severe disease. It is possible that the patients sensitized to Ani s 4 need to be careful about the severity of their allergic symptoms.
