Influence of preparations with peptides on innate and adaptive immunity

Abstract

Objective: to assess the dynamics of the immune system functioning when using mesotherapy with peptide complexes. Materials and methods: the observation group consisted of 26 women (from 35 to 55 years old) who received a course of mesotherapy with preparations containing peptides for the first time. Injections were carried out in a course of 5 procedures with an interval of 14 days. The exclusion criteria were the absence of same manipulations in the past, hormone replacement therapy, combined oral contraceptives, pregnancy, lactation, acute infections, somatic pathologies. The parameters of innate and adaptive immunity were studied before the course of procedures, right after it, 3 and 6 months after the course. Skin quality changes were assessed using the Aramo Smart Lite 300 dermatoscope. Results: improved skin quality, decreased skin creases, increased skin moisture. The obtained clinical improvements last for three months after the end of the course and there is a tendency for the effects to decrease after six months. In the functioning of the immune system, there is a redistribution of lymphocytes population in the peripheral bloodstream immediately after the course of mesotherapy. In addition, an increase in peripheral T-regulatory lymphocytes responsible for intraimmune suppression was documented. The activation of spontaneous oxygen-producing activity was noted. 3 months after the procedure, no significant changes in immunological parameters were found. 6 months after the course of procedures, a decrease in the level of T-lymphocytes with an increase in the expression of markers of early T-cell activation was recorded. In the humoral link, an increase in circulating B-lymphocytes was documented. In the parameters of innate immunity, there is a decrease in the spontaneous oxygen-producing activity of neutrophils. Conclusion: as a result of the study, a positive persistent clinical effect is documented, simultaneously with the mobilization of factors of innate and adaptive immunity. It is important to note the fact that the immune response restores completely within 6 months after a course of mesotherapy with peptide complexes, with still noticeable clinical results.
