Synthesis of cytokines during physiological pregnancy

The article is devoted to the study of the level of pro- and anti-inflammatory cytokines in women with a physiological pregnancy, which is of great importance in obstetrics. Studying the synthesis of cytokines makes it possible to identify disturbances in the course of pregnancy, which is of great practical importance. The authors conducted a study of the level of cytokines in women with physiological pregnancy. Purpose of the study: to study the serum concentration of pro-inflammatory (IL-1β, IL-6, TNFα, IFNγ) and anti-inflammatory (IL-4, IL-10) cytokines in the dynamics of physiological pregnancy.

The level of serum cytokines was studied in 94 women with a physiologically progressing pregnancy, who were registered with advisory clinics No. 14, No. 26, and No. 28 in Bukhara. The age of pregnant women ranged from 21 to 37 years, averaging 26.3±1.5 years. When compiling groups by trimester of pregnancy, it was revealed that: 35 women were in the first trimester of pregnancy; in 31 – the second trimester; and in 28 women – the third trimester of pregnancy. The control group consisted of 30 practically healthy non-pregnant women who were comparable in age. The levels of cytokines 1β, IL-6, TNFα, IFNγ, IL-4, and IL-10 was determined in peripheral blood serum using a set of reagents produced by Cytokin LLC (St. Petersburg, Russia) using the ELISA method according to the manufacturer’s instructions. Statistical processing of the obtained results was carried out using Student’s t-test using the standard Windows 2000 statistical software package. An increase in the level of proinflammatory cytokines (IFNγ, TNFα) was detected in the early stages of gestation compared with data from healthy non-pregnant women, which persisted in the second half of pregnancy against the background of an increase in anti-inflammatory cytokines (IL-4, IL-10). In the third trimester of pregnancy, a further increase in the serum level of pro-inflammatory cytokines (IL-1β, TNFα, IFNγ) was observed. The results of the studies indicate that at the level of the cytokine network there are mechanisms of fetoprotection, the violation of which can be the cause of pregnancy pathology.
