Peculiarities of allergy to plant foods in south-eastern Spain

Abstract

Allergy to fruits and vegetables is the most common primary food allergy in Mediterranean countries, especially the lipid transfer proteins (LTPs) syndrome. This study is the first research that studies multiple clinical, allergological and therapeutics characteristics of allergies to plants in the South-East of Spain, and assessing whether these characteristics differ in emergency room or outpatient clinic. This is a prospective study of patients who consult for the first time for allergy to vegetables at Granada, Spain. We record demographic data, symptoms, allergological study and indicated therapy. The characteristics obtained agree with the current bibliographic except the higher prevalence than other areas of positive sensitization of Pru p 3, Cor a 9 and Ara h 9, which predisposes to severe allergic reactions. We conclude: Allergy to plant food in Granada is a more severe phenotype than other geographic areas from Spain, especially in young adults sensitized by different LTPs and pollinosis to olive pollen.
