Cypress pollen does not cross-react to plant-derived foods
Background And Objective:
Some studies hypothesize the existence of cross-reactivity between allergy to Cupressus sempervirens pollen and plant-derived foods. We aimed to assess whether this holds true.
Methods:
72 patients monosensitized to cypress pollen were investigated for food allergy to peach, apple, tomato and Juniperius oxycedrus berry.
Results:
No patient had a history of clinical allergy or showed in-vitro or in-vitro reactivity to peach, apple, and tomato. Two patients scored positive on SPT with Juniperius oxycedrus berry but in-vitro tests ruled out cross-reactivity with the corresponding pollen.
Conclusion:
Airborne allergy to Cupressaceae pollen is not associated with allergy to plant-derived foods.
