Introduction: Pollen-food syndrome (PFS) is an immunoglobulin E-mediated reaction, caused by cross-reactivity between pollen and antigens of foods such as those in fruits, vegetables, and/or nuts, in patients with pollinosis.
Aims and Methods: The aim of this study was to present clinical manifestations of PFS, using a case series of six pediatric patients with PFS and pollen allergy referred to our Allergy and Clinical Immunology Department.
Results: The age at diagnosis ranged between 10 and 17 years old, and three of the patients were male. All patients reported experiencing oral allergy syndrome. The main foods reported as triggers were apple, peach, pear, kiwi and banana. The allergic diagnostic workup revealed sensitisation to PR-10 and profilins, the main proteins involved in PFS. Currently, all patients remain asymptomatic after the fresh fruits’ eviction.
Conclusion: We emphasize the importance of recognition of this entity to provide an adequate management.
