BACKGROUND: In 2012, we clarified that the prevalence of food-dependent exercise-induced anaphylaxis (FDEIA) was 0.018% among junior-high students in Yokohama, Japan. Furthermore, although different from FDEIA, one student who had completed oral immunotherapy developed anaphylaxis during exercise after eating causative food. However, there have been few large-scale epidemiological studies of FDEIA in elementary school children, so we conducted the epidemiological study among elementary school children in Yokohama to clarify the frequency and characteristic of FDEIA...

BACKGROUND: Reports on oral immunotherapy (OIT) for anaphylactic food allergy are lacking. We investigated the efficacy and safety of peanut OIT for anaphylactic patients. METHODS: We enrolled 22 peanut anaphylactic patients who underwent OIT between 2011 and 2013, all of whom demonstrated anaphylaxis during a baseline double-blind, placebo-controlled food challenge. After starting in-hospital OIT, participants gradually increased ingestion to 795 mg of peanut protein per day at home and then took a maintenance dose (795 mg) daily...

BACKGROUND: We evaluated the safety and efficacy of low-egg-allergen cookies (LAC) as low-dose oral immunotherapy (OIT) in children with severe egg allergy. We also examined the relationship between mild desensitization by low-dose OIT and serum biomarkers of allergy. METHODS: We enrolled 13 children with egg allergy who could not receive OIT with hard-boiled egg white (EW). For 11 participants, OIT was carried out using LAC for 3-4 months. Open food challenges with hard-boiled EW and blood samplings were performed before and after OIT...

Therapeutic tolerance restoration has been proven to modify food allergy in patients and animal models and although sublingual immunotherapy (SLIT) has showed promise, combined therapy may be necessary to achieve a strong and long-term tolerance. In this work, we combined SLIT with systemic administration of IL-2 associated with an anti-IL-2 monoclonal antibody (IL-2/anti-IL-2Ab complex or IL-2C) to reverse the IgE-mediated experimental allergy. Balb/c mice were sensitized with cholera toxin and milk proteins and orally challenged with allergen to elicit hypersensitivity reactions...

Although omalizumab (anti-IgE) is currently only approved for the treatment of asthma and chronic idiopathic urticaria, it has also been studied as an off-label treatment for numerous allergic conditions, including use as an adjunct to allergen immunotherapy in the treatment of allergic rhinitis, asthma, venom hypersensitivity, and food allergy. We conducted a review of publications involving the use of omalizumab with allergen immunotherapy, by searching PubMed with key search terms of "omalizumab" and "immunotherapy...

The prevalence of IgE-mediated food allergy is an increasing public health concern effecting millions of persons worldwide. The current standard of treatment is strict avoidance of the offending food or foods, and to date, there are no regulatory approved treatments for food allergy. A significant amount of research has been directed at various forms of food immunotherapy, including oral, sublingual, and epicutaneous delivery routes. Although oral immunotherapy has shown the greatest promise for efficacy in terms of the amount of protein that can be ingested, it has also demonstrated less tolerability and a less favorable safety profile compared with sublingual immunotherapy and epicutaneous immunotherapy, which offers the least protection but has the best safety and tolerability profile...

Currently, the management of people diagnosed with shellfish allergy relies on the avoidance of those foods. HDM immunotherapy has been reported to induce both shrimp allergy in non-allergic patients, and shrimp tolerance in shrimp-allergic patients. This article summarizes therapeutic options other than avoidance diet for shrimp allergic patients available once the diagnostic is established, such as production of hypoallergenic shrimp, use of immunotherapy with modified allergens, probiotics and Chinese herbal formulations...

BACKGROUND: Despite progress in single food oral immunotherapy, there is little evidence concerning the safety and efficacy of treating individuals with multiple food (multifood) allergies. We did a pilot study testing whether anti-IgE (omalizumab) combined with multifood oral immunotherapy benefited multifood allergic patients. METHODS: We did a blinded, phase 2 clinical trial at Stanford University. We enrolled participants, aged 4-15 years, with multifood allergies validated by double-blind, placebo-controlled food challenges to their offending foods...

Food allergy can result in considerable morbidity, impairment of quality of life, and healthcare expenditure. There is therefore interest in novel strategies for its treatment, particularly food allergen immunotherapy (FA-AIT) through the oral (OIT), sublingual (SLIT), or epicutaneous (EPIT) routes. This Guideline, prepared by the European Academy of Allergy and Clinical Immunology (EAACI) Task Force on Allergen Immunotherapy for IgE-mediated Food Allergy, aims to provide evidence-based recommendations for active treatment of IgE-mediated food allergy with FA-AIT...

Although there is no FDA approved therapy for food allergy, over the past decades, several routes of immunotherapy have been investigated for food allergy. Thus far, these therapies have shown variable levels of efficacy at desensitizing to foods, with oral immunotherapy (OIT) far more successful than sublingual immunotherapy (SLIT) or epicutaneous immunotherapy (EPIT). However, desensitization tends to be temporary, and safety remains a major concern with OIT. Moreover, although it seems logical that desensitization will result in fewer reactions, it is not clear whether OIT or other immunotherapies are associated with an overall lower or higher risk of reactions over the long term...

Importance: Epicutaneous immunotherapy may have potential for treating peanut allergy but has been assessed only in preclinical and early human trials. Objective: To determine the optimal dose, adverse events (AEs), and efficacy of a peanut patch for peanut allergy treatment. Design, Setting, and Participants: Phase 2b double-blind, placebo-controlled, dose-ranging trial of a peanut patch in peanut-allergic patients (6-55 years) from 22 centers, with a 2-year, open-label extension (July 31, 2012-July 31, 2014; extension completed September 29, 2016)...

Finding an effective curative treatment for food allergy is a research priority. Although oral immunotherapy (OIT) is effective at inducing desensitization, the temporary nature of this effect and high rates of adverse reactions have highlighted a need for novel strategies to improve tolerance induction and safety. One such strategy is the use of an adjuvant together with food immunotherapy to either suppress allergic reactions and/or modulate the underlying allergic immune response. In particular, the use of bacterial adjuvants seems to be a promising means of enhancing OIT-induced sustained unresponsiveness and warrants further investigation...

Treatment of IgE-mediated food allergies is limited to allergen avoidance and emergency treatment on accidental ingestion, which is not uncommon. In recent years, interest in interventional therapies to treat food allergy has increased significantly. Although oral, sublingual, and epicutaneous immunotherapy have shown promise in studies, none is approved as therapy for food allergy to date and questions remain regarding efficacy, safety, dosing, and duration of therapy.

Baked egg and baked milk are tolerated by most children who are allergic to hen's egg and cow's milk. Incorporating baked goods into the diets of allergic children may help them outgrow their primary allergy more quickly, with changes observed akin to immunotherapy. Benefits may also include increased quality of life and improved nutritional status. The search for a reliable biomarker to predict tolerance to baked goods is ongoing. Most children with a milk or egg allergy who are not previously tolerating egg or milk in baked goods should be offered an observed oral food challenge...

Food allergy occurs due to IgE- and mast cell-dependent intestinal inflammation. Previously, we showed that histamine-releasing factor (HRF), a multifunctional protein secreted during allergy, interacts with a subset of IgE molecules and that the HRF dimer activates mast cells in an HRF-reactive IgE-dependent manner. In this study, we investigated whether HRF plays any role in food allergy. Specifically, we determined that prophylactic and therapeutic administration of HRF inhibitors that block HRF-IgE interactions reduces the incidence of diarrhea and mastocytosis in a murine model of food allergy...

The prevalence of food allergies has been increasing at an alarming rate over the last few decades. Despite the dramatic increase in disease prevalence, the development of effective therapies has not kept pace. In this issue of the JCI, Ando et al. provide a causal link between histamine-releasing factor (HRF) interactions with IgE and food allergy in a murine model. Successful oral immunotherapy of both egg-allergic human patients and food-allergic mice was associated with sustained suppression of HRF-reactive IgE levels...

BACKGROUND: Peanut allergy is the most common cause of anaphylaxis and food-related death. However, there is currently no approved immunotherapy treatment. Hence, this warrants the need for relevant and convenient animal models to test for adequate immunotherapies. MATERIALS & METHODS: In this study, we compared three mouse strains: CD1, BALB/c and C57, to select a model of peanut allergy. After that, we conducted then a therapeutic study using an immunogenic peanut extract encapsulated in nanoparticles made with polymer Gantrez(®) following the solvent displacement method...

A 26-year-old female patient exhibited symptoms associated with egg allergy, which had been present since early childhood. The patient requested the treatment of egg allergy and was admitted to our hospital for rush oral immunotherapy. The threshold was determined by an oral food challenge test, after positive results on a double-blind food challenge test. The patient ingested dry powder of raw egg-white 5 times per day starting with a tenth of the threshold dose (3.0mg), followed by a 1.2-times increase every time...
