Anaphylaxis to sunflower seed
Anafilaxia à semente de girassol
Cristiana Sofia Ferreira; Bartolomé Borja
Abstract
Sunflower seed (Helianthus annuus) is an uncommon allergenic source frequently consumed in snacks, as component of some types of bread, as condiment in some dishes, and also used in animal feeding. Occasional cases of anaphylaxis to this seed have been reported in the current literature, mainly in workers occupationally exposed to sunflower allergens and bird breeders. The allergenic nature of the storage protein albumin 2S and the non-specific lipid transfer protein (nsLTP) of this seed has been described. The authors report the case and diagnostic approach of a seed anaphylaxis.

Resumo
A semente de girassol (Helianthus annuus) é uma fonte alergênica incomum frequentemente consumida em lanches, como componente de alguns tipos de pães, como condimento em alguns pratos, e também utilizada na alimentação animal. Casos eventuais de anafilaxia a esta semente têm sido relatados na literatura atual, principalmente em trabalhadores com exposição ocupacional a alérgenos de girassol e criadores de aves. A natureza alergênica da proteína de armazenamento albumina 2S e da proteína não específica de transferência de lipídios (nsLTP) dessa semente foi descrita. Os autores relatam o caso e a abordagem diagnóstica de uma anafilaxia por sementes.
