%X sunflower seed (helianthus annuus) sensitization occurs to storage proteins (2s albumins) and to lipid transfer proteins (ltps), but it rarely induces anaphylaxis. we report the case of a 32 year -old female with allergic rhinoconjunctivitis and three anaphylactic reactions minutes after eating sunflower seed. the first episodes occurred after eating sunflower seeds as a snack, and the last after eating potatoes fried in sunflower oil. skin prick tests were positive to sunflower seed, specific ige was 79 ku/l and immuno-cap isac£¿ revealed sensitization to cross -reactive ltps (npru p 3, nart v 3, rpar j 2). sunflower seed extract inhibited (60%) ige binding to nart v 3 and npru p 3, with no inhibition to the other allergens identified. epinephrine autoinjector device was prescribedand strict avoidance of sunflower seed and foods cooked in sunflower oil was advised.
