Cypress pollen does not cross-react to plant-derived foods.
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.


CONCLUSIONS
Airborne allergy to Cupressaceae pollen is not associated with allergy to plant-derived foods.
