Influence of natural factors Saki lake combined with “Berlition® 600” (Thioctic acidi) on immunoregulatory processes taking into account morphological changes of skin in patients with plaque psoriasis

Abstract

Objective. To study the effect of peloids Saki Lake and brine, combined with the drug “Berlition® 600” on immunoregulatory processes based on morphological and functional changes of the skin in patients with plaque psoriasis. Materials and methods. The study involved 90 patients with plaque psoriasis mild to moderate severity. The study group included - 45 patients receiving therapeutic mud treatments, and the brine baths in conjunction with the “Berlition® 600” in the control group - 45 patients treated with mud baths and RPMA. All patients using flow cytometry laser defined subpopulations of T-lymphocytes. The concentration of Ig A, M and G in the blood was determined by mikroturbidimetricheskim with monospecific antisera; proinflammatory and anti-inflammatory cytokines (IL-1a, IL-2, IL-8, IL-10, TNF-α) was measured by enzyme-linked immunosorbent assay (ELISA). Immunohistochemistry Skin biopsy were studied with the definition of CD3+, CD4+, CD8+ T-lymphocytes. Results and discussion. Patients in both treatment groups revealed an imbalance of T and B-cell immunity to the reduction in the number of helper-inductor (CD4+) and cytotoxic (CD8+) subpopulations of T-L in peripheral blood and increase in CD3+, with a predominance of CD8+ in psoriatic infiltrate amid overproduction of cytokines. Procedures for medical mud and the brine baths in combination with the drug “Berlition® 600” has a marked immunomodulatory effect due normalitsatsiey of T-cell immunity and reduction of the balance of cytokine profile, “clinical cure” and “significant improvement” reached 45 (100%) patients, the index regression PASI- 96,7 ± 1,3% DLQI-86 ± 2,1%. Conclusions. Peloids, balneotherapy in Lake Saki in combination with the drug “Berlition® 600” has a high clinical efficacy due to immunomodulatory, antiproliferative and anti-inflammatory effects and can be recommended as a differentiated, immunomodulatory therapy in patients with plaque psoriasis mild to moderate severity.
