Is the presence of a fur animal an exacerbating factor of atopic dermatitis in adults?

ABSTRACT

Atopic dermatitis is one of the most common inflammatory dermatoses in children and adults. To date, no clear relationship between the severity of AD and the exposure to dog and guinea pig-derived allergens has been established. AIM: The aim of the study was to assess the association between the specific serum immunoglobulin E levels (against dog and guinea pig) and the grade of skin symptoms measured with the SCORAD and VAS scales in the population of adult patients suffering from atopic dermatitis. MATERIALS AND METHODS: The study was performed in the group of 47 patients suffering from atopic dermatitis since infancy (30 women and 17 men). Concentration of IgE was measured by the fluoroenzymatic immunoassay. The Mann-Whitney's test was used to compare the distribution of specific IgE concentration and the distribution of atopic dermatitis grade. RESULTS: The statistically significant correlation between SCORAD and VAS scales, and the measured specific IgE concentrations for investigated fur animals was found. CONCLUSIONS: The study demonstrated that in the patients with atopic dermatitis the concentration of specific IgE was correlated with severity of the disease symptoms, including itch. This enables forecasting the course of the disease and selecting a group of patients who should immediately reduce their contact with allergen.
