RESUMO
Trinta a 60% das alergias alimentares em adolescentes e adultos são associadas à alergia ao pólen e estão incluídas na síndrome pólen-frutas (SPF). Esta síndrome é caracterizada por sintomas alérgicos provocados pela ingestão de frutas ou vegetais frescos em pacientes com rinite/rinoconjuntivite alérgica sazonal. Os autores apresentam o caso clínico de um adolescente que após sensibilização primária através de pólens de gramíneas e oliveira manifestou posteriormente, por reatividade cruzada, sintomas de alergia oral com a ingestão de frutas frescas. Após recurso ao método de diagnóstico Immuno-Solid-Phase Allergen Chip (ISAC) verificou-se que as profilinas foram as proteínas responsáveis pela reatividade cruzada.
ABSTRACT
In adolescents and adults, 30% to 60% of food allergies are associated with pollen allergy and are included in the pollen-food syndrome (PFS). This syndrome is characterized by allergic symptoms elicited by the ingestion of fresh fruits or vegetables in patients with seasonal allergic rhinitis/rhinoconjunctivitis. The authors present the clinical case of an adolescent who, after primary sensitization to grass and olive tree pollens, subsequently manifested by cross-reactivity symptoms of oral allergy with the ingestion of fresh fruit. After diagnostic workup with the Immuno- Solid-phase Allergen Chip (ISAC) assay, profilins were identified as the proteins responsible for the cross-reactivity.
