The purpose of research. The purpose was to investigate alpha-defensin levels in the circularly neutrophiles of atopic dermatitis and pyodermia patients in comparison with healthy donors.Materials and methods. 27 patients with atopic dermatitis, 31 patients with pyodermia in comparison with 17 healthy donors were investigated. Intracellular alpha-defensin levels in neutrophils in the peripheral blood were estimated by flow cytometry with mouse anti-HNP-antibodies (Hy cult biotechnology).Results. The alpha-defensins level in patients with atopic dermatitis and pyodermia was reduced in comparison with healthy donors. More expressed decrease of alpha-defensins level was obtained in patients with pyodermia and sever atopic dermatitis with skin infection.Conclusion. Thus, a decrease of alpha-defensins levels in atopic dermatitis and pyodermia patients, possibly, is a marker of the chronic bacterial inflammation and may cause chronic bacterial skin disease, St. aureus colonizations and tolerance to the therapy.
