Epidemiologic, Clinical and Socioeconomic Factors of Atopic Dermatitis in Spain: Alergológica-2005

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 specifi c 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
