  • Food allergy is common and sometimes life threatening for Korean children. The current standard treatment of allergen avoidance and self-injectable epinephrine does not change the natural course of food allergy. Recently, oral, sublingual, and epicutaneous immunotherapies have been studied for their effectiveness against food allergy. While various rates of desensitization (36% to 100%) and tolerance (28% to 75%) have been induced by immunotherapies for food allergy, no single established protocol has been shown to be both effective and safe. In some studies, immunologic changes after immunotherapy for food allergy have been revealed. Adverse reactions to these immunotherapies have usually been localized, but severe systemic reactions have been observed in some cases. Although immunotherapy cannot be recommended for routine practice yet, results from recent studies demonstrate that immunotherapies are promising for the treatment of food allergy.

  • Purpose. The purpose of this study was to compare the total lifestyle patterns. of allergy and non-allergy group. Method. The study was carried out to access the lifestyle patterns such as food intake, smoking, alcohol intake and exercise habits by questionnairing the no allergy people and 205 non-allergy people living in Seoul area. Results. 1. The proportion of eating stimulatory food materials-mainly hot and salty-of allergy group were significantly higher than those of non-allergy group. 2. In allergy group, the proportion of meat intake was significantly higher than that of non-allergy. 3. In allergy group, exercise habit was higher than that of non-allergy, but not significant. 4. In allergy group, smoking was lower than that of non-allergy, but not significant. 5. In allergy group, alcohol intake was lower than that of non-allergy, but not significant. Conclusion. Lifestyle patterens such as food intake(salt and meat) were significantly different by prevalence of allergy and allergy type, which suggested that lifestyle patterns of allergy people need to be studied to develop preventive stratagies for allergic reaction.

  • Food allergies affect 7~8% of infants and young children, and their prevalence appears to have increased in recent years. Food allergy refers to an abnormal immunological reaction to a specific food. These reactions can be recurrent each time the food is ingested. Food allergy manifests itself with a wide spectrum of clinical characteristics including IgE-mediated diseases as immediate reactions, non-IgE-mediated disorders as delayed reactions, and mixed hypersensitivities. As a consequence, the clinical picture of a food allergy is pleomorphic. A well-designed oral food challenge is the most reliable diagnostic test for infants and young children whose clinical history and physical examination point towards a specific food allergy. Food specific IgE antibody tests (RAST, MAST, skin prick test, Uni-CAP, etc) are an alternative tool to determine oral food challenge for IgE-mediated disorders, but not for non-IgE-mediated allergies. Moreover, parents often impose their children on unnecessary diets without adequate medical supervision. These inappropriate dietary restrictions may cause nutritional deficiencies. This review aims to introduce clinical perspectives of food allergy in infants and young children and to orient clinicians towards different strains of diagnostic approaches, dietary management, and follow-up assessment of tolerance development.

  • Food allergy refers to an immunologically mediated adverse reaction to food, mainly to proteinaceous constituents. Health implications vary between those individuals who experience mild physical discomforts to those with fast-acting, life-threatening anaphylactic reactions. The prevalence of food allergy is higher in children than in adults, estimated around 4-8% and 1-2% respectively in developed countries. Food allergy has no effective cure at the present time and total avoidance of causative foods is the most reliable prophylactic method currently recommended by the medical community. To help food allergic patients to make informed choices of their foods, mandatory labeling of selected food allergens has been introduced in several countries. All food allergen labelling provisions specify a set of allergens common to the regulated countries. Policy divergence, however, exists between countries by inclusion of additional allergens unique to specific countries and enforcement of specific labelling requirements. Such variations in food allergen labelling regulations make it difficult to manage allergen labeling in imported pre-packaged food products. This paper addresses two current issues in food allergen regulation: 1) an urgent need to determine true prevalence of food allergy in the Asia-Pacific region. This will enable refinement to the food allergen regulation to be more country-specific rather than simply adopting CODEX recommendations. 2) There is an urgent need for harmonization of food allergen regulation in order to prevent food allergen regulation becoming a trade barrier.

  • Many patients assume that allergic reactions against foods are responsible for triggering or worsening their allergic symptoms. Therefore, it is important to identify patients who would benefit from an elimination diet, while avoiding unnecessary dietary restrictions. The diagnosis of food allergy depends on the thorough review of the patients's medical history, results of supplemented trials of dietary elimination, and in vivo and in vitro tests for measuring specific IgE levels. However, in some cases the reliability of such procedures is suboptimal. Oral food challenges are procedures employed for making an accurate diagnosis of immediate and occasionally delayed adverse reactions to foods. The timing and type of the challenge, preparation of patients, foods to be tested, and dosing schedule should be determined on the basis of the patient's history, age, and experience. Although double-blind, placebo-controlled food challenges(DBPCFC) are used to establish definitively if a food is the cause of adverse reactions, they are time-consuming, expensive and troublesome for physician and patients. In practice, An open challenge controlled by trained personnel is sufficient especially in infants and young children. The interpretation of the results and follow-up after a challenge are also important. Since theses challenges are relatively safe and informative, controlled oral food challenges could become the measure of choice in children.

  • Objectives : The purpose of this study is to compare atopic dermatitis and food allergy of Korean Medicine with those of western medicine. Methods : We examined the relationship between atopic dermatitis and food allergy mainly in digestive system abnormalities through literature review. Results : Food allergy is classified into categories such as diarrhea, abdominal pain and cough caused by retention of undigested food(食積) and pimples(癮疹) in Korean medicine. The side effects caused by specific immune reactions occur repeatedly due to exposure to specific food allergen or retention of undigested food. Atopic dermatitis and food allergy are often coexisting and deeply related. Digestive system abnormalities can result not only in indigestion but also in immune function abnormalities. Food allergies are known to cause atopic dermatitis and the influx of food antigens exacerbates atopic dermatitis. This corresponds to atopic dermatitis due to abnormal digestive system(脾胃) accompanied by fever(熱), wind(風), and weakness(虛) with focusing on dampness(濕). A typical example of the relationship between atopic dermatitis and food allergy in Korean medicine is Tae-yeul (胎熱). Tae-yeul refers to atopic dermatitis caused by a sensitization to reaction to the dietary antigens of the mother through the placenta during the fetal life with a unusual genetic disposition. Conclusions : We compared korean medicine with western medicine for atopic dermatitis and food allergy. Atopic dermatitis caused by abnormal immune function due to ingestion of food antigen corresponds to dermatitis due to retention of undigested food(食積), digestive system(脾胃臟) problems in korean medicine.

  • According to the hygiene hypothesis, westernized and urbanized life style leads to the increase of allergic disease. This hypothesis supports the use of probiotic therapy for the prevention or treatment of food allergy. The probiotics which contains potentially beneficial microorganism have been used for the treatment of some gastrointestinal disorders and atopic disease as dietary supplements. Many results of studies support the immunologic bases of probiotics therapy. The most important mechanism is that probiotics suppress Th2-skewed immunity as the stimulation of regulatory T cell. The difficulties of diagnosis of food allergy, variable symptoms, many kinds of microorganism, diet style and non-standardized study designs are attributed to the variety and controversy of the effectiveness of probiotics in food allergy with infant and children. More studies is needed to confirm the efficacy of probiotics in infant and children with food allergy.

  • This study was conducted to investigate the status of food allergy knowledge and management of the teachers and operators of child care facilities in the Daejeon Area. Surveys of 262 teachers and 50 operators of child care facilities in Dong-gu and Jung-gu in Daejeon were conducted. The prevalence of food allergies was found to be 3.6% (102 children). The average score of teachers in the anaphylaxis knowledge survey was $0.18{\pm}0.22$. Additionally, the needs for food allergy education among teachers and operators was 88.2% and 98%, respectively. The survey revealed that all child care facilities in this study provide food service menus to parents, but only 14 facilities (28%) provided alternative food to children with food allergies, and some of these 14 facilities did not provide adequate alternatives. To ensure the safety and healthy growth of children with food allergies, it is necessary to provide food allergy education to teachers and operators, as well as to establish safe food service and allergy management systems in all child care facilities.
