Dictionary of Allergies .. Barley [(L) Hordeum vulgare]

Patients allergic to wheat may also react to rice, barley and sometimes oats [1]. The most potent allergens from barleyinclude the glycosylated monomeric (BMAI-1) and dimeric (BMAI-1) [2]. FPIES is a non-IgE-mediated gastrointestinal food hypersensitivity disorder. Food protein-activated intestinal lymphocytes elaborate inflammatory cytokines that result in increased intestinal permeability, malabsorption, dysmotility, emesis, diarrhea, pain, and failure to thrive. Decreased intestinal transforming growth factor beta and increased TNFalpha may be important in food protein-induced enterocolitis syndrome (FPIES). Cow's milk and soy are the most common causes of (FPIES), but cereal grains (rice, oat, and barley), fish, poultry, and vegetables may also cause FPIES. The majority of FPIES resolve by age of 3 years [3]. f6 is the symbol of Barley in RAST and CAP system. (See cereals).
