THE ANALYSIS OF ANAPHYLAXIS DIAGNOSED AT DERMATOLOGY OF TOKYO MEDICAL UNIVERSITY HOSPITAL

Abstract

There are few epidemiological reports of anaphylaxis since childhood. We herein examined cases of anaphylaxis diagnosed in our department. One hundred-thirty-two patients who were examined at the Dermatology Department of Tokyo Medical University Hospital between January 2011 and March 2017 and were prescribed epinephrine autoinjector (EpiPen®) for treatment were enrolled. The referral institution if any, severity of anaphylaxis, diagnostic method, causative antigen, and recurrence rate was examined. The referral rate was 54% while 46% of patients requested examination of their own accord. Anaphylaxis severity was mild to moderate in 75% of cases. Food allergy accounted for 71% of the symptoms, with wheat as the most common causative antigen, followed by Anisakis allergy. After diagnosis only 37% of patients continued periodic consultations, and 16 patients recurred anaphylaxis of the diagnosis. Wheat and WDEIA were the most frequent causes of anaphylaxis diagnosed in our department. We also found that as many as 15% of patients had Anisakis allergy, suggesting that it may be an important item in antigen testing.
