Pollen food syndrome

Abstract

Pollen food syndrome (PFS) is a description of oral allergy symptoms on exposure to particular foods that are closely related to the primary sensitising pollen allergen. PFS is a common phenomenon relating to certain protein component groups (profilin, PR10 and LTP). It is often overlooked, particularly in children. Symptoms usually occur after the onset of allergic rhinitis or sensitisation to aeroallergens. Clinical history is vital with allergy tests (Skin prick tests, IgE and IgE component resolved diagnostics) being a supplementary tool to assist diagnosis. There are currently no consensus guidelines for the investigation and management of PFS, however optimising allergic rhinitis treatment can be beneficial to severity of symptoms. This short article gives an overview of this common problem and offers advice about diagnosis and management.
