1143 patients were selected among atopic outpatients followed up at our Institution (Clinical Immunology-University of Brescia) on the basis of documented sensitization to one or more inhalant allergens. All patients had been investigated by skin prick tests employing a large panel of allergens. Specific sensitization had been confirmed by clinical history and when necessary by RAST. The patients were investigated retrospectively for the prevalence of sensitization to Paretaria. 880 patients were sensitized to one or more pollens and among these 427 (48.5) to Parietaria. Among pollen monosensitized patients (with no concomitant allergy to other inhalants), 222 were sensitized to Graminacee and 125 to Parietaria. In these groups there was no difference in prevalence of asthma. Our study thereby shows that the prevalence of sensitization to Parietaria in Brescia is higher than described in other cities in North Italy. Our findings are supported by pollen concentration in atmosphere as determined by Burkard pollen trap.
