Demographics and immunological characterization of hen's egg allergic patients.

SPT were performed with commercially available egg white extracts and are presented as wheel area (mm2). Specific IgE antibodies were measured by ELISA with coated native egg white (W), denatured egg white (Wd), native yolk (Y), and denatured yolk (Yd) extracts; results are expressed as specific IgE concentrations in µg/ml. IgE reactivity to Gallus domesticus allergens were determined by microarray using Immuno solid-phase allergen chips (ISAC) and given in as kUA/l. DBPCFC, double blind placebo controlled food challenge; AD, atopic dermatitis; AE, angioedema; AN, anaphylaxis; AS, asthma; CO, conjunctivitis; GI, gastrointestinal symptoms (including vomiting, diarrhea, and pain); n.p., not performed; OAS, oral allergy syndrome; RH, rhinitis; UR, generalized urticaria.
