PD17 - Food allergy profile in late adolescence in a tertiary healthcare facility

Results Among 56 patients (46 male, age range 14-22,5 years, median 16,6 years) 55% had positive family history of atopy, 64% reported atopic dermatitis and 80% asthma and/or allergic rhinitis. 1/3 developed their first reaction to a food allergen during infancy, the main allergens being egg (11%), milk (9%) and fish (7%).32% first experienced FA as preschoolers, 27% between 6-12 years and only 11% in adolescence. In 21/56 patients the first reaction was anaphylaxis. All subjects became tolerant to milk and egg before adolescence. The most common allergens in late adolescence were nuts (including peanut) (55%), fruits (25%), fish (23%) and sesame seed (9%). Nut allergy appeared in 48,4% (15/31 patients) in preschool years, in 25,8% between 6-12 years and in 25,8% during adolescence. The rates for fish allergy apparition were 69,2%(9/13 patients), 23,1% and 7,7%, respectively. Fruit allergy emerged in most patients between 6 12 years old. Only 2 patients became tolerant to fish and 3 to nuts before/during adolescence. Over half of the patients experienced at least 1 anaphylactic reaction and 20% had 2 or more. An adrenaline auto-injector was prescribed to 80% of the patients. Nevertheless, only 18% reported carrying it at all circumstances and 20% occasionally.
