Abstract

Prevalence of food allergic disease was examined by identifying the most common foods implicated in allergic reactions in Korea. Patients were subjected to test determining the amount of specific IgE antibody in serum against food allergens by CAP system. A total 9054 CAP analyses on egg white, egg yolk, cow milk, ${\alpha}-lactalbumin,\;{\beta}-lactoglobulin$, casein, wheat, rice, buckwheat, soybean, peach, crab, shrimp, pork, beef, chicken, tuna, salmon, mackerel, and food mix were undertaken. The results were considered to be positive when CAP value was same and/or greater than +2 (0.7 U/mL). Positive results of CAP analyses were 11.3% (1022/9054 cases), consisting of 336 on egg white, 266 on cow milk, 95 on egg yolk, 76 on soybean, 69 on ${\alpha}-lactalbumin$, 61 on casein, 58 on ${\beta}-lactoglobulin$, 39 on buckwheat, 12 on wheat, 3 on beef, 2 on crab, and 1 on rice, shrimp, pork, chicken or mackerel, and 0 on peach, tuna or food mix. Egg, cow milk, soybean, buckwheat, and wheat were identified as the most common allergic foods in Korea, showing an average of two different food sources for allergy per patient.

본 연구의 목적은 우리나라의 식품으로 인한 알레르기 발생 빈도를 파악하며 주 알레르기 원인 식품을 파악하는 것이다. 삼성서울병원에 알레르기 증상으로 1998년 5월부터 2001년 8월까지 방문한 환자의 혈청 특이 IgE 항체를 대상 식품에 대해 CAP 시스템을 이용하여 조사하였다. 총 9054건의 CAP 검사가 난백, 난황, 우유, ${\alpha}-lactalbumin,\;{\beta}-lactoglobulin$, 카세인, 밀, 쌀, 메밀, 대두, 복숭아, 게, 새우, 돼지고기, 쇠고기, 닭고기, 참치, 연어, 고등어 및 혼합식품에 대해 1707명의 방문자를 중심으로 이루어졌다. 조사 결과 CAP 수치가 +2(0.7 U/mL) 이상인 값을 양성으로 판단하였으며 CAP 검사결과 11.3% (1022/9054건)가 양성이었다. 각 알레르기 원인 식품별로는 난백이 336건, 우유가 266건, 난황이 95건, 대두가 76건 ${\alpha}-lactalbumin$ 이 69건, 카세인이 61건, ${\beta}-lactoglobulin$이 58건, 메밀이 39건, 밀이 12건, 쇠고기 3건, 게 2건, 쌀, 새우, 돼지고기, 닭고기, 고등어 가 각각 1건, 복숭아, 참치, 연어 혼합식품이 각각 0건이었다. 우리나라에서 제일 많은 5대 알레르기 원인 식품으로 계란, 우유, 대두, 메밀 및 밀이 확인되었으며 환자 1인당 평균 2가지의 알레르기 원인 식품을 갖고 있는 것으로 확인되었다.
