Background. Staphylococus aureus (S. aureus ) function in atopic dermatitis (AD) children skin is double-handed: an infectious trigger and an allergen. The study was aimed to evaluate a frequency of S. aureus enterotoxins IgE work out in children with infected AD skin and to compare IgE levels with infected AD severity. Methods. Specific IgE to S. aureus enterotoxins A and B (ImmunoCap, Phadia AB, Sweden) detected in serum of 90 children with infected AD. IgE levels were compared to severity of infected AD (Mann—Whitney Utest). Results. Specific IgE>0,35 kUA/l to S. aureus enterotoxin A frequency was of 0,29; to enteritoxin B 0,36; to one of them 0,43. IgE to S. aureus enterotoxins were elevated in 16 children with therapy resistant AD in compare to other cases of AD (р=0,00183). Conclusion. In children with infected AD S. aureus enterotoxins A or/and B are revealed in 25—50% of cases. In children with therapy resistant AD specific IgE level to enterotoxins is elevated in comparison to severe or average AD children.
