EVALUATION OF IMMUNOLOGICAL CHANGES IN PATIENTS WITH DIFFUSE FORM OF AUTOIMMUNE THYROIDITIS DURING LASER PHOTODYNAMIC THERAPY

The purpose of the study. To study the nature and dynamics of changes in humoral and local immunity during laser photodynamic therapy in patients with diffuse forms of autoimmune thyroiditis. Materials and methods. Laboratory tests of blood plasma were performed on 160 patients with long-lasting autoimmune thyroiditis in different age groups to determine humoral and local immunity. Here, information on the level of immunoglobulins A, G, M (IgA, IgG, IgM), the amount of interleukin-1 β (IL-1 β), tumor necrosis factor α (TNF-α) was determined in blood samples by the immunoenzyme method. The dynamics of laboratory parameters in all three groups of patients were studied on days 7 and 15 of treatment. These values were determined using reactives from “VectorBest” LLC (Russia). Results. In elderly patients with long-term autoimmune thyroiditis, a downward trend in TNF indices has been observed, which is an indication of the severity of the pathological process. The higher the amount of α2-MG in autoimmune thyroiditis and diffuse toxic urination, and the slower the normalization during treatment, the higher the probability of recurrence of the process. Conclusion. The combined use of modern laser technology in the treatment of patients with autoimmune thyroiditis expands the possibilities of conservative therapy and complements the arsenal of effective methods of treatment of this disease. The simplicity of the methods, ease of application, reliability, the absence of thermal effects on the thyroid gland creates ample opportunities for the application of this method in clinical practice.
