ABSTRACT
To determine the relative content of monocytes in the peripheral blood producing IL-4, IL-6, IL-10, IFNγ, to identify new criteria for predicting abortion before 22 weeks of gestation in women with the threat of early termination and recurrent miscarriage. Materials and methods. A survey of 91 women in the gestation period of 5-12 weeks was carried out. The main group consisted of 59 women with recurrent miscarriage and the threat of early termination at the time of the study. Depending on the outcome of pregnancy, the main group was subdivided into 3 subgroups: subgroup I – 44 women whose pregnancy ended in timely delivery, II – 8 women who had preterm labor, III – 8 women with termination of pregnancy up to 22 weeks ( missed pregnancy or spontaneous miscarriage). The control group consisted of 32 women with uncomplicated pregnancy. The relative content of IL-4 +, IL-6 +, IL-10 +, IFNγ + monocytes was determined by flow cytometry on FACSCanto II (Becton Dickinson, USA). In women with threatened early miscarriage and recurrent miscarriage, the percentage of IL-4 + and IL-10 + cells in the population of peripheral monocytes is significantly lower, while IL-6 + cells are higher compared to the control group (p = 0.0001 in in all cases), no statistically significant differences were found in the percentage of IFNγ + cells (p = 0.076). A retrospective analysis revealed that in the group of women with termination of pregnancy up to 22 weeks, there was a significant decrease in IL-10 + monocytes in the peripheral venous blood. Prediction of termination of pregnancy before 22 weeks of gestation is possible with a relative content of IL-10 + monocytes equal to 27.0% or less (sensitivity 87.5%, specificity 95.2%, accuracy 93.1%).
