- Abstract
Background: Although plant and fruit pollens are entomophilous and relevant in exposed workers, we have shown a high frequency of sensitisation and symptoms induction of peach tree pollen (PTP) and Prunus persica 9 (Pru p 9) in adults from areas of peach cultivars. Methods: We studied the sensitisation and clinical relevance of PTP and Pru p 9 in a large group of children and adolescents aged 3–19 years. A detailed questionnaire plus skin prick testing to prevalent allergens, PTP, and Pru p 9 were carried out. The clinical relevance was established by nasal provocation test (NPT) and symptom score index. Results: We evaluated 685 children (mean age 8.75 ± 3.3 years, median 9 years), 52% of them female. Sensitisation to PTP occurred in 20% of the cases following olive tree (33%) and Phleum pratense (26%). In a randomly selected subgroup of subjects sensitised to PTP, 30% were skin prick test-positive to Pru p 9. Most cases had rhinitis or rhinoconjunctivitis. NPT showed the relevance of PTP and Pru p 9 in the induction of symptoms. Conclusion: PTP and Pru p 9 are relevant in the induction of sensitisation and respiratory symptoms in children and adolescents. This allergen should be evaluated in children living in regions of peach tree cultivars.
