Effect of combined phototherapy and regulatory polypeptide selank on cytokine blood profile of patients with atopic dermatitis

Abstract

Aim. To evaluate the effectiveness of complex therapy using the regulatory polypeptide selank and combined narrow-band medium-wave and wide-band long-wave ultraviolet (UV) radiation in the correction of the cytokine blood profile and immunoglobulin E (IgE) level in patients with atopic dermatitis (AD).Material and methods. In a group of 124 patients with medium-heavy AD (61 men, 63 women; average age 23.7 ± 6.06 years), a comparative analysis of the effect of therapy on the interleukins (IL) -1β,-4,-10,-13, immunoglobulin E (IgE) blood levels was performed. We compared the results of basic drug treatment (BT), additional prescription of selank (S), combined UV phototherapy (CFT) in the range of 311 nm and 320–400 nm, as well as complex therapy (S + CFT + BT).Results. The immune status of AD patients is characterized by high blood levels of IL‑1β,-4,-10,-13 and IgE in comparison with healthy individuals. Standard drug therapy had the least effect on the cytokine profile and level IgE blood of patients. The use of selank increases the anti-inflammatory effect of BT. The regulatory effect on cytokine activity and level IgE is even more significantly enhanced with the use of CFT. The most pronounced immunocorrective effect was demonstrated by complex therapy with the use of combined UV radiation techniques and selank.Conclusions. The use of a combined narrow-band medium-wave (311 nm) and wide-band long-wave (320–400 nm) UV radiation and regulatory polypeptide drug (selank) causes the most pronounced positive effect on the cytokine blood profile and IgE level in patients with AD, which indicates a greater anti-inflammatory activity of this treatment method (p < 0.001) compared to the monotherapy groups and basic therapy (p < 0.001).
