Introduction: Atopic dermatitis (AD) is a chronic inflammatory dermatosis, often with a concomitant allergy. The ImmunoCAP ISAC (Immuno Solid-Phase Allergen Chip) test is a novel method to determine the allergenic phenotype in a given patient. Aim: In this study, we used the ImmunoCAP ISAC test to analyze allergic phenotypes in adult patients with AD. Material and methods: The study included 19 adult patients with AD. The severity of AD was assessed using SCORAD index. Serum concentrations of total IgE were determined by means fluoro-enzyme immunoassay (FEIA). The levels of aslgE were measured with the ImmunoCAP ISAC kits. Results: Positive results of the ISAC test were documented in 84.2% of the study subjects. All patients synthesized aslgE against species-specific respiratory allergens; major components of animal allergens (57.87%), tree pollen allergens (47.3%), grass pollen allergens (42.1%), dust mite allergens (26.3%) and major allergen of mugwort (26.3%). 47.3% of the subjects were sensitive to cross-reactive allergenic components, most often proteins of the lipocalin family (57.8%), followed by PR-10 (26.3%), PR-14 (21%) and PR-5 proteins (21%). aslgE against species-specific allergens were found in 103% of the study subjects. No statistically significant relationships were observed between the severity or duration of AD and the prevalence and levels of aslgE against the allergens included in the ISAC panel. However, duration of AD correlated significantly with the serum concentration of total IgE. Conclusions: The ISAC test is suitable for determination of the allergenic phenotype in a given patient, and as such has an unquestioned diagnostic and therapeutic value.
