Wheat allergy: diagnosis and management
Antonella Cianferoni Department of Pediatrics, Division of Allergy and Immunology, The Children’s Hospital of Philadelphia, PA, USA Abstract: Triticum aestivum (bread wheat) is the most widely grown crop worldwide. In genetically predisposed individuals, wheat can cause specific immune responses. A food allergy to wheat is characterized by T helper type 2 activation which can result in immunoglobulin E (IgE) and non-IgE mediated reactions. IgE mediated reactions are immediate, are characterized by the presence of wheat-specific IgE antibodies, and can be life-threatening. Non-IgE mediated reactions are characterized ...

Reduction Rate of Specific IgE Level as a Predictor of Persistent Egg Allergy in Children.
CONCLUSIONS: ΔEWsIgE12mo can be used as an early independent predictor of tolerance acquisition of IgE-mediated egg allergy in children. PMID: 31172718 [PubMed]

Clinical Features and Culprit Food Allergens of Korean Adult Food Allergy Patients: A Cross-Sectional Single-Institute Study.
CONCLUSIONS: Wheat, fruits with or without PFAS, and crustaceans are important and frequent causative allergens in Korean adult FA; these allergens differ from those found in childhood FA. It is notable that non-classic allergies, such as PFAS, FDEIA, and α-Gal allergy, are the important causes of anaphylaxis in Korean adult FA. PMID: 31332982 [PubMed]

Wheat Allergy in Children – New Tools for Diagnostics
Conclusions and Clinical RelevanceWheat allergy diagnostics is difficult, even by using sophisticated component methods. Our results confirm earlier findings about gliadins and identify the dimeric AAI 0.19, as a relevant allergen in clinically reactive patients when compared to non‐reactive subjects. The accuracy of wheat allergy diagnosis may be improved by measuring IgE responses to several components of wheat.This article is protected by copyright. All rights reserved.

How to diagnose food allergy
Purpose of review To assess the recent studies that focus on specific immunoglobulin E (sIgE) testing and basophil activation test (BAT) for diagnosing IgE-mediated food allergies. Recent findings The sIgE to allergen extract or component can predict reactivity to food. The cutoff value based on the positive predictive value (PPV) of sIgE can be considered whenever deciding whether oral food challenge (OFC) is required to diagnose hen's egg, cow's milk, wheat, peanut, and cashew nut allergy. However, PPV varies depending on the patients’ background, OFC methodology, challenge foods, and assay methodology. Component-...

Anaphylaxis in a food allergy outpatient department: one-year review.
Conclusion. In accordance to other studies, milk and egg were the most implicated allergens in children. Anaphylaxis in adults reflects the Mediterranean sensitization pattern. Exercise was the most relevant cofactor. PMID: 29384116 [PubMed - as supplied by publisher]

Age-Based Causes and Clinical Characteristics of Immediate-Type Food Allergy in Korean Children.
CONCLUSIONS: The 5 major causative foods of immediate-type FA in Korean children were cow's milk, hen's eggs, wheat, walnuts, and peanuts. The distribution of causative foods was considerably distinctive according to different age groups. Anaphylaxis was reported in 30.5% of immediate-type FA cases. PMID: 28677356 [PubMed]

When nutrition and allergy collide: the rise of anaphylaxis to plant foods
Purpose of review: Interest in nutrition is increasing, but in the world of internet health gurus, whilst the nutritional benefits of fruits and vegetables are extolled, wheat is often vilified. This review will assess the positive nutritional effects of plant foods in relation to allergy prevention, the effectiveness of gluten-avoidance and the likelihood of anaphylaxis to fruits and vegetables. Recent findings: Although the numbers of people who report gluten sensitivity is rising, hard evidence of mass sensitivity to gluten is scant. Also, the avoidance of wheat containing foods could lead to nutritional imbalance and ...

Epidemiological link between wheat allergy and exposure to hydrolyzed wheat protein in facial soap
ConclusionsAn epidemiological relationship between wheat allergy and contact exposure to HWP has been documented. This study implicates a possible role of contact exposure to food‐derived protein hydrolysates as a risk factor for the development of food allergy manifesting itself as anaphylaxis.This article is protected by copyright.

Prevalence and longitudinal trends of food allergy during childhood and adolescence: results of the Isle of Wight Birth Cohort study
ConclusionFood allergy is highly prevalent in infancy with partial resolution during late childhood. However, a number of children acquire new food allergy during adolescence resulting in a relatively higher prevalence at 18 years.This article is protected by copyright. All rights reserved.

Food Allergy and Asthma: Is There a Link?
AbstractPurpose of reviewTo describe and understand the links and interactions between food allergy and asthmaRecent findingsFood allergy and asthma are characterized by an increasing prevalence. Moreover, food allergy and asthma often coexist. Both conditions are associated with each other in different ways. It has been shown that food allergy is a risk factor of developing asthma. Atopic dermatitis appears to be the common denominator in this interaction. Loss-of-function variants of the filaggrin mutation result in an impaired epidermal barrier function and have been shown to be a risk factor for the development of atop...

Low Concentration of Fecal Valeric Acid at 1 Year of Age Is Linked with Eczema and Food Allergy at 13 Years of Age: Findings from a Swedish Birth Cohort
Conclusions: Our findings lend further support to the notion of early childhood as a critical period when allergy may be programmed via the gut microbiota. Higher levels of fecal valeric acid may be characteristic of a protective gut microbiota and/or actively contribute to protection from eczema and food allergy.Int Arch Allergy Immunol

Wheat allergy in children evaluated with challenge and IgE antibodies to wheat components
ConclusionMany children diagnosed as wheat allergic have out‐grown their allergy, and are unnecessarily on a wheat‐free diet. The levels of IgE‐ab to wheat gluten‐derived components correlated well with wheat challenge outcome and severity.This article is protected by copyright. All rights reserved.

Patterns of suspected wheat-related allergy: a retrospective single-centre case note review in 156 patients
Conclusion Wheat allergy can manifest in different disease entities, rendering a detailed case history and challenge mandatory. Patient age, occupation, concomitant allergies (food or inhalant) and atopic dermatitis are important factors for evaluation.
