Diagnosis and management of oral allergy syndrome (pollen-food allergy syndrome)
ثبت نشده
چکیده
INTRODUCTION — The oral allergy syndrome (OAS) describes allergic reactions that occur upon ingestion of certain fresh fruits, nuts, vegetables, or spices in pollen-sensitized individuals. The symptoms result from contact urticaria of the mucosal surface that contacts the food. Symptoms are usually limited to the mouth and throat and observed with raw forms of the food, because the responsible allergens are rapidly inactivated by digestion and cooking, although this is not uniformly true. Systemic reactions are observed in 2 to 10 percent of patients, and reactions to cooked plant foods (including roasted nuts) are possible.

Review Article Oral Allergy Syndrome: An Update for Stomatologists
Oral allergy syndrome (OAS) is an allergic reaction in the oral cavity subsequent to the consumption of food such as fruits, nuts, and vegetables. It occurs mainly due to homology of proteins of pollen to the proteins of fruits and vegetables. In OAS, the immune system produces antibodies that are directed against the proteins of pollen and structurally similar proteins in food, hence, resultin...

متن کاملIntroductory lecture: Pollen food allergy syndrome
The term pollen-food allergy syndrome (PFAS) defines a series of clinical symptoms appearing shortly after the ingestion of plant-derived foods in subjects with pollen allergy. The patients with PFAS are primarily allergic to pollen and subsequently react to food allergens as a consequence of the homology between pollen and plantfood proteins. The two highly conserved proteins responsible for t...
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 کاملOral allergy syndrome--the need of a multidisciplinary approach.
Oral allergy syndrome (OAS) is one of the most common types of food allergy. The syndrome includes itching and swelling of the lips, palate and tongue, usually after consuming fresh fruits and vegetables. The underlying pathogenic mechanism is cross-reactivity between IgE antibodies specific to pollen, and antigens in food, such as fresh fruits, vegetables and nuts that are structurally similar...
