Oral allergy syndrome and risk of food-related anaphylaxis: a cross-sectional survey analysis
نویسندگان
چکیده
Background Oral Allergy Syndrome (OAS) is an IgE-mediated allergic response to fresh fruits, nuts and vegetables caused by cross-reactivity between pollen allergens and structurally similar food proteins. Alder pollen is a prominent allergen in coastal British Columbia, present at high levels from FebruaryApril. We hypothesized that this exposure may lead to increased prevalence of Alder pollen allergy and OAS. We sought to determine our population-based prevalence, cross-reactivity patterns, and incidence of food-related anaphylaxis.

Background: There is a lack of information regarding anaphylaxis that is triggered by the peanut and nuts in countries with emerging economies. We aimed to identify the factors that are related to the prevalence of secondary anaphylaxis that results from ingesting peanuts or nuts.

The best recognized intestinal manifestation of food allergy is food allergic (food-sensitive) enteropathy. The feature of enteropathy may include lymphocyte and plasma cell infiltration, epithelial abnormality, or crypt hyperplastic villous atrophy, and impairing absorption, enterophaty continues while the food remains in the diet, remitting on an exclusion diet, and usually recurring on food ...

These disorders are chronic conditions in which the immune system becomes hypersensitive to some food products. It is estimated that 8% of children under the age of three have a type of food allergy. The common allergenic foods include cow’s milk, wheat, peanuts, egg, soy and fis...
متن کاملCross-reactivity between aeroallergens and food allergens.
In patients with respiratory allergy, cross-reactivity between aeroallergens and foods may induce food allergy, symptoms ranging from oral allergy syndrome to severe anaphylaxis. Clinical entities due to IgE sensitization to cross-reactive aeroallergen and food allergen components are described for many sources of plant origin (pollen-food syndromes and associations, such as birch-apple, cypres...
متن کاملExercise-related anaphylaxis with food allergy to cross-reactive LTPs
Background In food dependent exercise-induced anaphylaxis, a food challenge followed by an exercise test, being the gold standard for diagnosis, might not be feasible under certain circumstances. Therefore, in vitro diagnostic tests can be helpful to clarify severe forms of exercise-related hypersensitivity syndromes. We report two patients with food allergy to non-specific LTPs presenting as e...
