THE INFLUENCE OF TOPICAL GLUCOCORTICOSTEROIDS ONCYTOKINE GENE EXPRESSION IN THE SKIN AND PERIPHERALBLOOD OF ATOPIC DERMATITIS PATIENTS

Abstract

Background. To investigate the influence of mometasone furoate 0,1% cream on cytokine gene expression in the skin and peripheral blood of atopic dermatitis (AD) patients comparing with control. Material and methods. 40 AD patients were included in the study and divided into 2 groups. group 1 patients were given continuous course of mometasone furoate 0,1% cream treatment for 14 days. group 2 patients were given indifferent emollient elobase cream for 14 days. Clinical efficacy of the treatment was assessed on the following features: SCORAD index, Investigators global Assessment (IgA) score and subjective assessment of itch and dryness of the skin according to skin area to be studied. Skin samples and peripheral blood of atopic dermatitis were used as material for immunological study. Interleukin (IL)1B, IL2, IL2r, IL4, IL5, IL6, IL7, IL8, IL10, IL 12A, IL12B, IL15 (total), IL15 , IL17A, IL18, IL23, IL28, IL29, Interferon (IFN)-ƒ, Tumor necrosis factor (TNF), Transforming growth factor beta 1 (TGFB1), forkhead box P3 (FOXP3) gene expression were defined in the skin and peripheral blood of AD patients by realtime reverse transcription polymerase chain reaction (RT-pCR). Results. positive clinical effect was found with all AD patients on the mometasone furoate 0,1% cream therapy background for 14 days and also dryness, rushes and skin itch decreased. Stаtistical significant decrease of proinflammatory cytokines IL2, IL2r, IL5, IL8, IL12В, IL23, IFN-ƒ gene expression was marked. They are the markers of chronic inflammation and Th1 immune response. Studying peripheral blood after mometasone furoate 0,1% cream treatment increase of TGFB1, FOXP3 gene expression level was found. no significant changes of cytokine gene expression in AD patients, who got elobase cream were found. Conclusion. Antiinflammatory activity of mometasone furoate 0,1% cream was shown by its influence on proinflammatory cytokines IL2, IL2r, IL5, IL8, IL12В, IL23, IFN-ƒ gene expression in the skin and mechanisms of immune response in moderate and severe AD patients.
