Oral allergy syndrome/pollen-food syndrome (OAS/ PFS) affects up to 70% of patients with birch-pollen allergy. Prevalence is likely to continue to increase as the prevalence of inhalant allergies rises. Homologous proteins in fruits, vegetables, and pollens of grasses, trees and weeds are responsible for PFS. Component-resolved diagnosis (CRD) with recombinant allergens may assist with the diag...

BACKGROUND AND AIMS The pathogenesis of oral-intestinal allergy syndrome (OIAS) has not been well understood. Published data indicate that galectin (Gal) 1 has immune regulatory functions. This study tests a hypothesis that Gal1 inhibits oral-intestinal allergy syndrome. METHODS Mice were sensitized to peanut extracts (PE) via the buccal mucosa with or without using Gal1 together. RESULTS U...

Case Report A 16-year-old boy presents to the allergy clinic with complaints of perioral itching and tingling after handling apples at his father’s fruit stall. He had experienced such symptoms on previous occasions, but this time he has developed mild lip swelling and tongue itching, as well. He has a history of seasonal allergic rhinitis that is controlled by nasal steroid spray. His father i...

Background Allergenic tropomyosins are highly cross-reactive panallergens found in various invertebrates. Sensitized patients can develop allergic responses ranging from oral allergy syndrome to severe anaphylactic reactions after the ingestion of tropomyosin-containing food. The usual routs of sensitization to tropomyosin include the airborne exposure to various mites and cockroaches and the o...

allergy to wheat is a common food allergy. in spite of this fact, there is not enough literature regarding the features and outgrowing of this allergy. the objective of this study was to evaluate the manifestations of this allergy and to follow the patients to evaluate whether outgrowing allergy happens again and when it occurs. eight wheat allergic patients diagnosed between 2000 and 2001 were...

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...

In spite of popular beliefs, the relationship between eczema and food allergy still puzzles researchers and clinicians, which in part is due to the variety of mechanisms involved in various types of allergy. One has to realize the differences between hypersensitivity reactions to food proteins (allergens capable of initiating immediate hypersensitivity or immune complex reactions) and low-molec...
