Abstract

Purpose of reviewThe purpose of this paper is to review and discuss studies on molecular diagnosis in fruit and vegetable allergy.Recent findingsCeleriac, carrot and tomato are the most prevalent allergenic vegetables, whereas fruit allergy is mainly induced by apple, peach and kiwi. Component-resolved molecular diagnosis has been recently applied in two well-defined patient groups with kiwifruit and celeriac allergy, respectively. In kiwifruit allergy Act d 1 and Act d 3 were identified as potential marker allergens for severe symptoms. For celeriac allergy, however, such markers are still missing. In both studies component-resolved molecular diagnosis approach improved in particular sensitivity compared to extract-based diagnostic test assays.SummaryFood and vegetable allergy can be acquired both via a direct sensitization over the gastrointestinal tract and via a primary sensitization to pollen or latex. The diagnosis of fruit and vegetable allergy in birch pollen-sensitized patients should not be excluded on a negative IgE testing to extracts. Bet v 1-related allergens are often under-represented in extracts. Few recombinant allergens derived from fruits and vegetables are nowadays commercially available and facilitate diagnosis of fruit and vegetable allergies.
