Effect of tree pollen specific, subcutaneous immunotherapy on the oral allergy syndrome to apple and hazelnut

Abstract

The study shows that SIT with extracts containing birch pollen has a positive impact on OAS to apple or hazelnut in birch pollen-allergic individuals. In spite of this outcome, the amount of apple/hazelnut tolerated is still small. Thus, the effect of SIT on the patients' management of OAS remains limited.
