Galactose- α-1,3-galactose (alpha-gal) allergy: first pediatric case in a series of patients in Spain.

CONCLUSIONS: A review is also made of the disorder which, due to its variable clinical expression, is referred to as alpha-gal syndrome. The study concludes that a diagnosis of alpha-gal allergy should be considered in patients with urticaria-anaphylaxis of uncertain origin or manifesting after the administration of vaccines or products of bovine/porcine origin.

Alpha-gal allergy is associated with immunoglobulin E (IgE) antibodies to galactose- α-1,3-galactose (alpha-gal), a carbohydrate found in beef, pork, and lamb. First described in the adult population in 2009 by Commins et al., this syndrome is associated with delayed anaphylaxis, angioedema, and urticaria with symptom onset 3 to 6 hours after eating red meat.1,2,3 Bites from ticks, namely the Lone Star Tick (Amblyomma americanum) in the United States, are associated with production of IgE antibodies to alpha-gal, resulting in an immune system primed to react to foods containing the antigen in patients who previously ...

ConclusionsThe α-Gal syndrome is a regionally common form of food allergy that: has a characteristic but not universal delay in symptom onset; includes gastrointestinal symptoms; can develop at any time in life; and, is equally common in otherwise non-atopic individuals.

This study — known as the Learning Early About Peanut or LEAP trial — showed that children at high risk of developing peanut allergies who are introduced to peanuts at 4 months to 6 months old had a significantly lower risk of developing a peanut allergy than those who waited until they were 5 years; 1.9% of the kids who had peanuts early developed an allergy, compared with 13.7% of the kids who waited. The LEAP trial formed the basis for Monday’s new recommendations, which encourage the early introduction of peanut products in infants at high risk for allergies. But most babies are not at high risk, and ...

ConclusionsWDEIA is a relatively rare but potentially severe food allergy. Understanding this allergy is therefore important for a correct diagnosis.ResumenAntecedentes y objetivoLa ω-5 gliadina (ω5G) se considera el alérgeno principal en la anafilaxia inducida por ejercicio dependiente del trigo (WDEIA).

Eosinophilic esophagitis (EoE) is a chronic immune mediated disease. As EoE is largely food driven, elimination diets (ED) are one of the two primary modalities used to treat EoE 1,2 Options include empiric EDs (6, 4, or 2 food EDs) or targeted EDs based on food allergy testing.3,4 Recently, children with EoE have been reported to develop immediate hypersensitivity reactions with reintroduction of previously IgE tolerated milk.5,6,7,8 Herein, anaphylaxis to previously tolerated wheat in an adult with EoE, and diffuse urticaria from soy reintroduction in a teen with EoE are presented.

These days, it can seem like just about everybody has a food allergy. But according to a new study, about 11% of American adults actually do. Yet 19% of adults believe they have a food allergy, even though some don’t have the diagnosis or symptoms to back it up, according to findings published in JAMA Network Open. This discrepancy suggests that quite a few adults are conflating allergies with less-severe food intolerances, which typically come with minimal digestion-related symptoms, the researchers write. If someone is truly allergic to a food, eating it can trigger a potentially life-threatening immune response. (...
