Clinical benefit of component-resolved diagnosis in Japanese birch-allergic patients with a convincing history of apple or peach allergy

In northern Japan, birch pollen is the major allergen in pollinosis, while oral allergy syndrome (OAS) is caused primarily by apple and peach, and is almost exclusively related to birch pollinosis. To clarify the clinical benefit of allergen-based component-resolved diagnosis (CRD) in Japanese birch-allergic patients with OAS, we present an analysis of IgE profiles in response to crude extracts and recombinant component-resolved allergen to birch pollen and Rosaceae fruits allergens.
