Une anaphylaxie sévère à la mangue dans le cadre d’un syndrome armoise-apiaceae-mangue chez une enfant de 11 ans

Abstract

Mango allergy is rare but tends to increase due to the more frequent consumption of exotic fruits. We report the observation of an 11-year-old child who had severe anaphylaxis after eating a whole mango with a grade 3 reaction according to the Ring and Behrendt classification. She had already consumed it before without any reaction. She also had rhino-conjunctivitis for several years due to mugwort pollen, revealing the mugwort-apiaceae-mango syndrome. The mango skin prick test was positive at 4mm for native fresh fruit and 5mm for industrial mango juice. Specific IgE for mango and mugwort were 1.45 and 26.7kU/L, respectively. She also showed sensitization for some apiaceae, carrots and celery at 1.66 and 0.72kU/L respectively, that she consumed without any problem. In the presence of a mango allergy, it is advisable to look for cross-reactions with other allergens due to the cross-reactivity of mango proteins with respiratory and food allergens in the context of mugwort-apiaceae-mango syndrome.
