Prevalence of allergic diseases is increasing worldwide, including food allergy. It is different between countries because food allergy can vary by culture and population. Prevalence of food allergy in Indonesia is unknown; therefore it is not known yet the burden and impact of food allergy in our population. However, we already start to formulate guidelines for diagnosis and management of food allergy, especially cow's milk allergy.

Wheat is a common cause of food allergy. Wheat-induced anaphylaxis (WIA) and wheat-dependent exercise induced anaphylaxis (WDEIA) are severe forms of immunoglobulin E (IgE) mediated allergic reaction to wheat protein. As the diagnosis of WIA or WDEIA is not easy because of the risk of oral challenge, identification of specific IgE of various wheat proteins is helpful for diagnosis. In Korea, there are only a few reports on WIA in adults. We report six cases of WIA diagnosed on the basis of clinical history and specific IgE of wheat proteins or provocation test. For immunologic evaluation of severe wheat allergy including WIA and WDEIA, it is important to measure specific IgE to each component of wheat including gluten and omega-5 gliadin not just measuring wheat-specific IgE.

PURPOSE: The information in the internet is increasing and the number of people using the Internet to obtain medical information is increasing rapidly too. But, compared to the amount of information, the quality of information is extremely variable. To assess the accuracy of medical information on the Internet, the quality of information about food allergies available on the internet examined. METHODS: Online searches using the phrase "food allergy" were conducted on five major Internet search engines. The first 50 web pages generated by each engine were examined. Making an exception of the web pages which were inaccessible, irrelevant, and duplicated, sixty out of two hundred and fifty web pages were evaluated. Information scores were developed from 1(no statement) to 4 (sufficient) and designed to assess how well the web pages mentioned the summary, symptom, diagnosis, treatment, and education of the patients, and emergent management. RESULTS: When classified by ownership, there were six(10%) oriental clinics, twelve(20%) hospitals, twenty one(35%) profit-making institutions, fourteen(23%) non-profit institutions and seven others (12%). The mean information score(IS) was 10.7. Summary got the highest IS(2.25) and the education for patients and supporters got the lowest IS(1.33). Medical institutions such as hospital and clinic got 12.33 and non-medical institutions got 10.25. But there were no statistically significant differences between these two institutions(P=0.107). CONCLUSION: Overall, the quality of information on food allergy through the Internet was poor. The main reasons are unlimited listings of related information on the Internet and an absence of a reviewing process of the information. Therefore, people should not entirely rely on the Internet for medical information and medical-related institutions such as hospitals, schools, clinics and relevant academic associations should develop an Internet system to improve the quality of information.

Food allergy has emerged as an important public health problem affecting people of all ages in many countries. The prevalence varies according to age, geographic regions, and ethnicity. For several years, many studies have suggested that the prevalence of food allergy is increasing at an alarming rate, for unclear reasons. Conversely, some studies have also provided findings that sensitization to common food allergens did not increase. Increased recognition rather than an actual increase in patients with IgE-mediated food allergy might lead to the increases in the prevalence of self-reported or physician-diagnosed food allergy. It is also noted that the prevalence of food allergy differs even in the same region according to the study design, i.e., hospital-based or community-based studies. Despite these limitations, epidemiologic data are important because they provide useful information on diagnosis, treatment, and prevention of food allergy. This review focuses on advances in the epidemiology of food allergy in Korean children.

There are many types in food allergy, and the most common is mediated by IgE. Currently, the diagnosis of food allergy mainly relied on skin prick test and serum specific IgE of allergen extract, which can not identify cross-sensitization. Component-resolved diagnosis (CRD) can identify the major allergen components and cross-components of food allergens, which plays an important role in dietary guidance, prognosis monitoring and diagnosis of special types of IgE-mediated food allergy. This article enumerates clinical characteristics of the IgE-mediated common food allergies, such as milk, egg and seafood allergy, and special type of food allergy, such as cat pork syndrome, oral allergy syndrome, α-gal syndrome and food-dependent exercise-induced anaphylaxis, summarizes the advances of CRD in these types of IgE-mediated food allergy, in order to provide an evidence for the diagnosis, treatment and prevention of IgE-mediated food allergy.

7.Neonatal food allergy.
Chinese Journal of Contemporary Pediatrics 2015;17(4):408-413
Food allergy is defined as abnormal immune response elicited by food intake, in which a variety of clinical symptoms will appear as a result of physiological dysfunction and/or tissue damage. Possible mechanisms for food allergy include gastrointestinal tract barrier damage, failure to induce oral immune tolerance, intrauterine sensitization, and allergen transmission during pregnancy and breastfeeding. Hereditary and environmental factors can also contribute to the disease. Gastrointestinal disorders are the main clinical manifestations of the disease. However, hypoalbuminemia, growth retardation, and even acute circulatory failure or shock may occur in severe cases. Oral food challenges are the "gold standard" for the diagnosis of food allergy. Avoidance and replacement of the responsible food are the only effective treatment options for neonatal food allergy. The use of probiotics can offer protection against the disease.

PURPOSE: The purpose of this study was to establish the diagnostic decision point (DDP) of peanut specific IgE (sIgE) for predicting the outcome of oral food challenge (OFC). We also evaluated the usefulness of sIgE to peanut components (Ara h 1, 2, 3, 8, and 9) in diagnosing peanut allergy. METHODS: Korean children aged over 12 months with a suspected peanut allergy were enrolled. Diagnosis of peanut allergy was confirmed by an open OFC or through the convincing history of anaphylaxis. Cutoff levels of sIgE to peanut and peanut components were determined by analyzing receiver operating characteristic curves. RESULTS: Forty-eight children (22 boys and 26 girls) with a suspected peanut allergy were enrolled. The previously established DDP for peanut-sIgE antibodies (14 kU/L) showed a sensitivity of 22.7%, specificity of 100%, positive predictive value (PPV) of 100%, and negative predictive value of 60.4% in our study population. The median levels of peanut-sIgE (5.4 kU/L vs 1.1 kU/L, P<0.001) and Ara h 2-sIgE (0.8 kU/L vs 0 kU/L, P<0.001) were significantly higher in the peanut allergy group than in the peanut tolerance group. The peanut-sIgE concentration indicating a PPV of 100% was 10.3 kU/L. The Ara h 2-sIgE level of 4.0 kU/L had a PPV of 100%. CONCLUSIONS: Our results showed that the cutoff levels for peanut (10.3 kU/L) and Ara h 2 (4.0 kU/L) established in this study is useful for the diagnosis of peanut allergy in Korean children.

PURPOSE: Buckwheat is one of the most common allergen in food allergy, the pathomechanism is IgE-mediated, type I immune reaction. Antigenicity of Buckwheat is extremely strong, and hypersensitivity symptoms included asthmatic attacks, urticaria eruption, gastrointestinal disorders even anaphylactic shock. The purpose of this study is to evaluate diagnostic significance of allergy skin test and allergy history and analyze clinical features of buckwheat allergy confirmed by oral provocation test. METHODS: We carried out the retrospective study on 55 patients who had been performed oral buckwheat provocation test at Yonsei university children's allergic clinic. RESULTS: 1) 40 out of 55 cases(72.7%) showed positive buckwheat oral provocation test. 2) The most common clinical finding after oral provocation test was urticaria. 60% showed severe allergic reactions such as asthma attack or anaphylactic shock. 3) The rate which past history and positive skin test corresponded to oral provocation test was very high(86.1%). CONCLUSIONS: The most valuable diagnosis of food allergy is oral provocation test. However, predictive value of allergy skin test and past history was very high in buckwheat allergy. Our study suggest that the troblesome oral provocation test may be not needed in all cases of suspicious buckwheat allergy patients.

10.Diagnosis of food allergies: the impact of oral food challenge testing
Asia Pacific Allergy 2013;3(1):59-69
A diagnosis of food allergies should be made based on the observation of allergic symptoms following the intake of suspected foods and the presence of allergen-specific IgE antibodies. The oral food challenge (OFC) test is the most reliable clinical procedure for diagnosing food allergies. Specific IgE testing of allergen components as well as classical crude allergen extracts helps to make a more specific diagnosis of food allergies. The Japanese Society of Pediatric Allergy and Clinical Immunology issued the 'Japanese Pediatric Guideline for Food Allergy 2012' to provide information regarding the standardized diagnosis and management of food allergies. This review summarizes recent progress in the diagnosis of food allergies, focusing on the use of specific IgE tests and the OFC procedure in accordance with the Japanese guidelines.
