Objective: To analyze the clinical and epidemiologic characteristics of the population with atopic dermatitis (AD) consulting in Allergology services in Spain.

Materials and Methods: The study was a multi-center, observational, descriptive, cross-sectional epidemiologic study with prospective collection of data on patients consulting for the fi rst time in Allergology services in Spain. By means of a data collection record, personal and specific variables were collected during the calendar year 2005 from a total of 4991 patients with AD.

Results: AD was diagnosed in 171 patients (3.4% of patients seen in Allergology services), which represented no signifi cant change with regard to the Alergológica-1992 study. In 72% of cases, AD was associated with other allergic disorders. The mean age of the onset of clinical manifestations of AD was 1 year and 4 months. During the fi rst consultations, the suspected diagnosis of AD was established in 83% of cases. In 58% of cases the cause was considered idiopathic and 42% were associated with sensitization to allergens. In 10% of patients with AD the triggering allergens were foods and in 26% aeroallergens. Most patients (94%) received hydrating skin and drug
treatment (anti-histamines 73%, topical corticoids 49%, calcineurin inhibitors 31%). Only 10% of patients followed an exclusion diet.

Conclusions: No signifi cant increase in the demand for AD consultations was observed in comparison with Alergológica-1992. AD was frequently associated with other allergic disorders. In few cases was food involved in the etiology of the disease. In most cases nothing more than topical drug treatment was indicated.
