Cupressaceae pollen in the atmosphere of Ascoli Piceno (Central Italy) and sensitization of allergic subjects

The aim of this work is to study the incidence of pollinosis in the Health District of Ascoli Piceno, Central Italy (U.S.L.24), this being an underestimated pathology from the clinical point of view and also as a result of the recent introduction of this taxa in the National Aeroallergen Network. Since 1990, 5055 patients of both sexes with respiratory symptomatology of suspected IgE mediated aetiology have been examined in our Centre with the Skin Prick Test (SPT) using allergen panels including Cypress; 171 (3.38%) patients were found to be positive to this allergen. These results show that the subjects with symptoms in the period January–March in most cases have a sensitization toCupressus pollen and new studies will evaluate the possibility of specific immunotherapy.
