Red meat allergy in Sweden: association with tick sensitization and B-negative blood groups.
To the Editor: Over the past few years, allergy to mammalian meat has been identified as a new syndrome of food allergy presenting as symptoms of delayed severe allergic reactions after consumption of red meat (beef, lamb, or pork). These allergic reactions are directed against the carbohydrate galactose-a-1,3-galactose (a-Gal). In the initial studies on red meat allergy, Commins et al observed...
متن کاملRed meat allergy induced by tick bites: A Norwegian case report.
Summary Food allergies, especially delayed hypersensitivity reactions, are often challenging for both patients and clinicians. Here, we report the case of a 64-year-old man who had allergic reactions six hours after eating a meal containing red meat. He reported that he had several tick bites in months before the reaction. High serum specific IgE levels of alpha-gal confirmed the diagnosis of a...
متن کاملThe red meat allergy syndrome in Sweden
In the last decade, a novel type of food allergy presenting with severe allergic reactions several hours after consumption of red meat has been recognized. The allergic responses are due to IgE antibodies directed against the carbohydrate epitope galactose-α-1,3-galactose (α-Gal) found in mammalian meat. This review presents the red meat allergy syndrome in Sweden, discusses the features of the...
متن کاملMammalian meat allergy following a tick bite: a case report
The alpha-gal allergy is an emerging IgE-mediated reaction against the galactose-alpha-1,3-galactose carbohydrate found in mammalian meats. Patients with this condition will develop anaphylactic symptoms 3-6 h after the ingestion of mammalian meat food products such as beef, pork or lamb. The prevalence of this allergy is drastically increasing and severe reactions including anaphylactic shock ...
متن کاملTick-induced allergies: mammalian meat allergy, tick anaphylaxis and their significance
Serious tick-induced allergies comprise mammalian meat allergy following tick bites and tick anaphylaxis. Mammalian meat allergy is an emergent allergy, increasingly prevalent in tick-endemic areas of Australia and the United States, occurring worldwide where ticks are endemic. Sensitisation to galactose-α-1,3-galactose (α-Gal) has been shown to be the mechanism of allergic reaction in mammalia...
