Oral allergy syndrome/pollen-food syndrome (OAS / PFS) affects up to 70% of patients with birch-pollen allergy. Prevalence is likely to continue to increase as the prevalence of inhalant allergies rises. Homologous proteins in fruits, vegetables, and pollens of grasses, trees and weeds are responsible for PFS. Component-resolved diagnosis (CRD) with recombinant allergens may assist with the diagnosis of this condition in the future. As there is currently no proven therapy for this syndrome, cooking and avoidance of offending fruits and vegetables are the only options.
