Abstract

We examined two hundred and thirty-two out-patients, ranging in age from 50 to 75 yrs. All patients were submitted to skin-tests: prick and, if it was necessary, intradermal reactions and/or RAST. Allergens employed were Gramineae, Parietaria, Olea, dermatophagoides Farinae, dermatophagoides Pteronyssinus, house dust, cat and dog skin scales. One hundred and twenty-eight subjects had positive responses to one or more aeroallergens. Asthma was the most frequent condition both in skin-positives and in skin-negatives. For 58% of skin-positives and 51% of skin-negatives the symptoms' onset was more than 10 yrs before our check. In 58.6% of patients we found positive reaction to dermatophagoides Farinae, in 51.5% to house dust, in 47.6% to dermatophagoides Pteronyssinus, in 34.3% to Gramineae, in 28.9% to parietaria and in 14.8% to olea. Fifty-four skin-positives subjects carried out lung function tests; in twenty-eight of them we found a bronchial obstruction. In more than 50% of the subjects, which had shown a reactivity to aeroallergens, we prescribed a specific hyposensitization. These data suggest that skin tests results in elderly patients can have a relevant role in preventive and pharmacological treatment, improving life quality.
