[PATHOGENETIC FEATURES AND METHODS FOR TREATMENT OF VARIOUS FORMS OF ROSACEA]

The aim of the work was to study the features of the pathogenesis of various clinical forms of rosacea (the presence of mite Demodex folliculorum, the determination of VEGF, IL-2 IL-6, IL-8) and, based on the obtained results, to ensure adequate methods of therapy. Mite identification was performed by microscopy. The concentration of cytokines in patients with various clinical forms of rosacea (papulopustular form 15 patients, steroid form - 15, erythematous telangiectic form - 10, Ophthalmo Rosacea - 3, rhinophyma - 3) was determined by enzyme immunoassay using appropriate monoclonal antibodies and expressed in samples. Based on the results we obtained in the local treatment of patients with papulopustular rosacea (with a high population density of demodicosis ticks and an increased concentration of IL-8 in the blood), 1% ivermectin cream was applied externally to the skin of the face 1 time per day every day for the entire course of treatment (3-4 months). In patients with erythematous-teloangiectatic form (with a high cytokine VEGF, IL-8), a combined phased use of 1% pimecrolimus cream 14 days and 0.5% bromonidine tartrate gel was administered once a day - 14 days (with a single course of 1 month). In patients with a steroid form of rosacea with a high concentration of cytokines (IL-2, IL-6, IL-8), 1% pimecrolimus was administered 2 times a day - 1 month, 1% ivermectin 1 time a day - 14 days. During therapy, patients with advanced treatment were divided into 2 groups. Patients of group 1, who received externally 1% ivermectin 1 time per day as the main therapy, in the evening for 16 weeks. Group 2 applied 1% ivermectin and 1% pimercolimus cream for 16 weeks. In group 2 patients showed a significant improvement in a shorter time (4 weeks compared to 8 weeks in 1 group of patients). Taking into account the torpid flow and the difficulty of rosacea therapy, the pathogenetic approach when choosing new external preparations, opens promising directions for further deeper study of the pathophysiological mechanisms underlying the individual clinical forms of dermatosis. At the same time, the efficacy and safety of using ivermectin, pimecrolimus, and brimonidine tartrate in the treatment of various forms of this dermatosis suggests their widespread use in practical dermatology.
