A recent study published in the Developmental Period Medicine was on the state of immunity in pregnancies associated with urogenital infection complicated by intrauterine infection. This comparative study involved the examination of 250 pregnant women with urogenital infection and with ultrasonographic signs of intrauterine infection, and their newborns, in order to assess the state of cellular and humoral immunity components and nonspecific resistance. Here, patients were retrospectively divided into two groups: the study group included 93 pregnant women who developed intrauterine infection; the comparison group comprised 157 pregnant-carriers of perinatally significant infection who gave birth to conditionally healthy children; and the control group consisted of 50 healthy women with a physiological pregnancy. The results showed that in the gestation period under investigation, the development of intrauterine infection in pregnant women with urogenital infections was found to be associated with a deficiency of T-helpers/inducers, an increase in thymus-dependent lymphocyte killer activity, a high content of interleukin (IL)-1β, tumor necrosis factor (TNF)-α in the systemic circulation, and a decrease in the level of IL-10, secondary to the oppression of the effector link of phagocytic neutrophils of peripheral blood. From the findings, it was stated that an increased concentration of systemic proinflammatory cytokines IL-1β, IL-6 and TNFα with a simultaneous decrease in the IL-10 content and suppression of the killing activity of peripheral blood phagocytes reflects the presence of an active inflammatory process in the mother-placenta-fetus system and can be one of the factors affecting the development of intrauterine infection in pregnancy, complicated by urogenital infection.
