OBJECTIVE: Pollen-food allergy syndrome (PFAS) is an IgE-mediated allergic reaction to certain foods due to prior sensitization to pollen allergens. The data about the prevalence of PFAS in adults in Turkey is not sufficiently reported. Our objective was to investigate the frequency and clinical features of PFAS in adult patients with seasonal allergic rhinitis (SAR).
PATIENTS AND METHODS: A total of 222 patients with SAR were enrolled in our outpatient allergy clinic at Hacettepe University, during a ten-month period. A questionnaire was used to evaluate patients and to categorize those who experienced obvious allergy symptoms consistent with PFAS. Atopy was assessed by a standard skin prick test panel including common aeroallergen extracts.
RESULTS: Among 222 patients with a diagnosis of SAR, 31 had patient reported PFAS (31/222, 14%). Among them, 23 (74.2%) were females, and their mean age was 32.29±9.24 years. The most common symptoms were isolated oropharyngeal symptoms (58.1%), followed by urticaria (51.6%) after culprit food ingestion. The most frequent culprit foods were eggplant, walnut, kiwi, peach, and melon. The predominant sensitizing aeroallergen was grass pollen.
CONCLUSIONS: PFAS can be frequently observed in adults who are followed up for SAR. The most frequently involved foods are eggplant, walnut, kiwi, peach, and melon in Ankara Province. The symptoms of PFAS are usually localized in the oropharyngeal area and are self-limited.
