Discoordination of the processes of activation and suppression of immunocompetent cells during mesotherapy with hyaluronic acid

Objective . The study aimed to assess the dynamics of the systemic immune response in patients during mesotherapy with hyaluronic acid (HA). Materials and methods . The observation group included 26 women who received the first-time mesocorrection with drugs based on hyaluronic acid (HA). Injections of low molecular weight HA were carried out according to standard methods in a course of 5 procedures with an interval of 14 days. The parameters of the innate and adaptive immune response were studied before and two weeks after the end of the course. The skin condition was assessed by dermatoscopy (Aramo Smart Lite 300, Southern Korea). Results . The clinical effect of the course of procedures was reflected in the subjective improvement in the appearance. The improvement was confirmed by hardware analysis, which recorded an increase in hydration, a smoothing of the skin relief, and a decrease in the depth of wrinkles. At the end of the course, redistribution of lymphocyte populations towards natural killer cells and B-lymphocytes was revealed with a decrease in the total number of T cells. The antibody production of immunoglobulins of classes M and G was increased, the serum content of Ig A and IgE was reduced, the number of both T-effectors and T-lymphocytes with immunosuppressive activity increased. Changes in the neutrophil system were characterized by the inhibition of the production of reactive oxygen intermediates; the dynamics of the expression of Toll-like receptors by monocytes was ambiguous. Conclusion . The results of the study confirmed the active involvement of the factors of innate and adaptive systemic response in the cosmetic effect, which manifested itself immediately after mesotherapy as systemic dysregulatory immune changes.
