“…Analyzing the indicators of the content of natural killers (CD16 + ) in the 1 st and 2 nd groups, a statistically significant decrease in their relative number was noted compared to the control group (by 2.9 and 1. 3 When analyzing the functional state of immunocompetent cells, it was found that the level of CD16 + CD69 + in group 2 was lower than the values in the control group and in group 1 by 2.0 times (p < 0.05). The content of CD8 + CD25 + in the 2 nd group was statistically significantly lower than in the control group (p < 0.05).…”

External genital endometriosis (EGE) is one of the common gynecological diseases of women of reproductive age with a relapsing, progressive course that worsens the quality of life of patients due to pain, emotional imbalance, fear of relapse and possible surgical intervention. Currently, endometriosis is recognized as one of the most common diseases associated with infertility. Thus, among fertile women with preserved childbearing function, the disease is generally diagnosed in approximately 6-7%, while among patients suffering from infertility, its frequency can reach 20-48%.However, the causes that determine reproductive dysfunction in patients with EGE are not well understood. Much attention is currently paid to the role of immunity in the formation of endometriosis. Patients with EGE show changes in both local immunity factors and immunological components of circulating blood.Purpose of the study: the study of factors of innate and adaptive immunity in patients of reproductive age with external genital endometriosis (EGE).The study included 71 patients with various stages of external genital endometriosis, the control group included 24 patients without endometriosis. Determination of the population composition of peripheral blood lymphocytes, the level of monocytes expressing TLR, activation markers, was carried out by laser flow cytometry — Immunotex (France), Caltag (USA), FITC (fluorescein isothiocynate) — labeled CD3, CD4, CD8, CD16, CD19, HLA-DR, CD282, CD284 and PE (phycoerythrin) - labeled with CD25, CD69, CD95, CD107a, CD14.External genital endometriosis is characterized by: at stages I-II of the disease - a violation of the early stages of the innate immune response (an increase in the number of monocytes expressing TLR-4, a violation of the activation and differentiation processes of immunocompetent cells, which is reflected in a decrease in the expression of CD16, CD8, CD16+HLA-DR+, CD16+CD107a+, CD8+CD107a+, at III-IV stages of the disease, there is a decrease in the level of CD16 and activation markers CD69, HLA-DR, CD107a on their surface, which is combined with a decrease in the expression of CD8, CD16, HLADR and CD107a on their surface. CD95+ and CD8+CD95+ were found at various stages of EGE.The results obtained allow us to understand the features of the functioning of innate and adaptive immunity at various stages of external genital endometriosis, and the studied immunological parameters can be used as diagnostic criteria for the formation of various stages of EGE. These data can serve as a theoretical basis for further identification of markers of EGE progression, as well as the mechanisms underlying immune inflammation.
