Food allergy is a pathological, potentially deadly cascade of immune responses to molecules or molecular fragments that are normally innocuous when encountered in foods, such as milk, egg, or peanut. As the incidence and prevalence of food allergy rise, the standard of care is poised to advance beyond food allergen avoidance coupled with injectable epinephrine treatment of allergen-induced systemic reactions. Recent studies provide evidence that oral immunotherapy may effectively redirect the atopic immune responses of food allergy patients as they ingest small but gradually increasing allergen doses over many months, eliciting safer immune responses to these antigens...

BACKGROUND: Food allergy negatively impacts quality of life and can be life-threatening. Cashew nuts can cause severe reactions in very small amounts, and they are included in a group of foods most commonly responsible for causing food allergy. Polyphenols and polyphenol rich juices have been demonstrated to complex with peanut allergens. Here, the interaction between cashew nut allergens and polyphenol rich juices is evaluated biochemically and immunologically. RESULTS: Various juices, including pomegranate (POM), blueberry (BB), and concord grape (CG) juices, were evaluated for polyphenol content and formation of polyphenol-cashew allergen complexes...

PURPOSE OF REVIEW: Intimate behaviours may represent an unusual way of exposure to a culprit allergen, or the frame for sex-related allergies due to triggers typically linked to that situation. The present review aims at summarizing the state of the art about the topic, in order to spread the awareness and the basic know-how in the field of sexual-related allergies. RECENT FINDINGS: Kiss-related IgE-mediated reactions are caused in sensitized partners mainly by the passive transport of allergenic molecules through saliva, skin or oral mucosa...

RATIONALE: 'Generic' immunoassays for peanut cannot discriminate between allergen levels in peanut derived food products or therapeutics. Clinical trials of oral immunotherapy are strengthened by using standardized peanut preparations, with defined doses of major allergens. OBJECTIVE: This paper describes measurement of Ara h 1, Ara h 2 and Ara h 6 in peanut foods and in peanut flour extracts used for allergy diagnosis and oral immunotherapy. METHODS: Monoclonal antibody-based enzyme immunoassays for Ara h 1, Ara h 2 and Ara h 6 were used to compare allergen levels in peanut (n=19) and tree nut (n=16) butter, peanut flour (n=11); oils (n=8); extracts used for diagnosis and oral immunotherapy (n=5); and the National Institute for Standards and Technology Peanut Butter Standard Reference Material® 2387...

BACKGROUND: Peanut allergy is a life threatening condition which lacks regulatory-approved treatment. T regulatory type 1 (Tr1) cells are potent suppressors of immune responses and can be induced in vivo upon repeated antigen exposure or in vitro using tolerogenic dendritic cells (DC-10). Whether or not oral immunotherapy (OIT) leads to antigen-specific Tr1 cell induction has not been established. OBJECTIVES: To determine whether peanut-specific Tr1 cells can be generated in vitro from peripheral blood of peanut allergic (PA) individuals at baseline or during OIT, and whether they are functional as compared to peanut-specific Tr1 cells induced from healthy controls (HC)...

BACKGROUND: Peanut immunotherapy studies are conducted with the aim to decrease the sensitivity of patients to peanut exposure with the outcome evaluated by testing the threshold for allergic response in a double-blind placebo-controlled food challenge. The clinical relevance of increasing this threshold is not well characterized. OBJECTIVE: We aimed to quantify the clinical benefit of an increased threshold for peanut-allergic patients. METHODS: Quantitative risk assessment was performed by matching modeled exposure to peanut protein with individual threshold levels...

BACKGROUND: Conventional data analysis of flow cytometry-based basophil activation testing requires repetitive, labor-intensive analysis that hampers efforts to standardize testing for clinical applications. Using an open-source platform, we developed and implemented a programmatic approach to the analysis of the basophil activation test (BAT) by flow cytometry. METHODS: Using the BÜHLMANN FlowCAST® assay, peripheral blood from peanut allergic patients undergoing oral immunotherapy was incubated with peanut allergens (Arah1, Arah2, Arah6, whole peanut extract) and stained with fluorescent antibodies to CCR3 and CD63 for the development of a data-driven programmatic analysis using Bioconductor and R...

BACKGROUND: Peanut oral immunotherapy (POIT) decreases the probability of accidental recurrent systemic reactions but reactions from the therapy itself are frequent. OBJECTIVE: The purpose of this economic analysis was to characterize the potential cost-effectiveness of POIT. METHODS: Cohort simulations were used to evaluate the effect of POIT for children with peanut allergy. A POIT with probiotic was used in the base-case simulation and long-term survival was modeled using age-adjusted mortality together with the risk of food allergy-associated mortality...

BackgroundDespite its high prevalence, relatively little is known about the characteristics of patients with multiple tree-nut allergies.MethodsPatients (n=60, aged 4-15 years), recruited for a multiple food (tree nuts, peanut, milk, egg, soy, sesame, and wheat) oral immunotherapy (OIT) study, filled a questionnaire on their initial allergy evaluation. Medical records were reviewed. At OIT enrollment (median interval, 7.5 years), patients underwent oral food challenges (OFCs) to foods still eliminated.ResultsThere was significantly less evidence for eliminating tree nuts compared with other foods, as reflected by a lower rate of acute reaction to the offending food, either as the trigger for initial allergy evaluation (5...

BACKGROUND: Quality of life (QOL) is impaired in patients with food allergy and improves following oral immunotherapy (OIT). However, the treatment itself is prolonged and demanding. We examined changes in patient QOL during OIT for food allergy. METHODS: The FAQLQ-PF was administered to children aged 4-12 years undergoing OIT for milk, peanut, or egg allergy, at the beginning and after 4 months of treatment. Patients were categorized as improved, unchanged, or diminished FAQLQ-PF (>0...

Food allergy results from failure in oral tolerance that usually occurs in infancy or early childhood. Exposure to peanut and hen's egg via the inflamed and disrupted epithelial barrier in children with severe atopic dermatitis is a risk factor for the development of allergy to these foods and supports the hypothesis that epicutaneous exposure in the absence of oral feeding is an important pathway of allergic IgE sensitization in infants. In recent years, the collective evidence has pointed toward the protective effect of an early feeding with peanut and egg in children with eczema, taking advantage of the pathways underlying oral tolerance to counteract epicutaneous exposure...

Food allergy (FA) is a serious health problem, and severe FA such as food-induced anaphylaxis can often be life threatening. The incidence of FA has been increasing especially in children. They usually develop early in life and affect up to 10% of children. The 2 most common food allergens worldwide are milk and eggs, while the third one varies depending on the countries: peanuts in the United States and Switzerland, wheat in Germany and Japan, tree nuts in Spain, sesame in Israel, and walnuts in Korea. These common food allergens are different and difficult to identify because of differing study methodologies, population, geography, age, and dietary exposure patterns...

The clinical utility of molecular diagnostic approaches in allergy investigation is being recognized increasingly to play a significant role in the management of allergic patients. Determining the sensitization pattern, which is best achieved through the use of component resolved diagnostics (CRD), allows effective risk stratification, appropriate treatment and patient selection for immunotherapy. In order to assess the diagnostic service provisions for in-vitro allergy testing across Europe, a survey was carried out via the total immunoglobulin (Ig)E and specific IgE external quality assurance schemes run by UK National External Quality Assessment Service (NEQAS) Immunology, Immunochemistry and Allergy...

Food allergy is estimated to affect approximately 8% of children in the USA. This is a disease without any known treatment or cure and, for some, a disease that can be quite severe, even life-threatening. While recent advances in potential treatment have made remarkable strides, with two food-targeted immunotherapy products now in phase III trials, perhaps the biggest gains in the field have come in the advent of potential preventative strategies to avoid the development of food allergy in high-risk individuals...

BACKGROUND: Concurrent sensitization to peanut (PN) and tree nuts (TN), the most dangerous food allergies, is common. Current oral immunotherapy (OIT) is not fully satisfactory. OBJECTIVE: To determine whether the herbal formula B-FAHF-2 (BF2) ameliorates PN/TN OIT adverse reactions and enhances persistence of a tolerant state. METHODS: Concurrently sensitized PN-, walnut- (WN) and cashew (CSH)-allergic mice received 1-day PN/WN/CSH rush OIT plus 3 weeks of maintenance dosing, with or without 3 weeks prior and 3 weeks BF2 co-treatment...

Current clinical research focuses on food allergen-specific immunotherapy through oral (OIT), sublingual (SLIT), or epicutaneous (EPIT) routes. Immunotherapy relies on the delivery of gradually increasing doses of specific allergens to induce desensitization (defined as temporary antigen hyporesponsiveness that depends on regular food ingestion) and, ultimately, tolerance (defined as the ability to ingest food without symptoms despite prolonged periods of avoidance or irregular intake). Although the majority of the patients treated with OIT achieve desensitization, only a minority achieves tolerance...

BACKGROUND: Anaphylaxis is a life-threatening condition for which we have limited therapeutic options. Although specific immunotherapy for food allergies is becoming more effective, it is still laborious and carries substantial risk of adverse events. On the other hand, regulatory dendritic cell (DC) therapy is effective in mouse models of allergic disease and has been shown to work with TH2 cells from atopic asthmatic patients. OBJECTIVE: We assessed whether DC immunotherapy could reverse food allergen sensitivity in mouse models to provide proof of concept relating to their use in the clinic...

Food allergy is a common health problem worldwide, with increasing prevalence during recent decades. The only approved treatments for food allergy are food avoidance and administration of emergency medications in case of accidental exposure, which negatively affects patients' quality of life, so new treatments are highly desirable. Different food immunotherapy modalities have recently been used, with variable success rates in the induction of desensitization and tolerance, and different numbers and types of adverse reactions...
