The study of placental lactogen by immunohistochemistry in histological sections of the placenta during physiological pregnancy and on the background of iron deficiency anemia in the aspect of chronic placental insufficiency. It is established that during gestation against the background of iron deficiency anemia decreases the production of placental lactogen by syncytiotrophoblast of the chorionic villi and correlates with the state of the blood of the pregnant woman. The optical density of immunohistochemical staining for placental lactogen of the free trophoblast reflects the degree of maturation of the chorionic tree of the placenta in iron deficiency anemia in pregnant women. Chronic placental insufficiency caused by immaturity of the chorionic villi can be compensated at the level of metabolism.

The authors of the article investigated the quantitative parameters of the placental chorion tree during physiological pregnancy and gestation against the background of iron deficiency anemia. It has been established that iron deficiency anemia in pregnant women inhibits the development of the placental chorionic tree, which is explained by the formation of chorionic villi (through trophoblastic and free processes) and violation of the transition of terminal villi to terminal "specialized" villi. The diagnosis of chronic placental insufficiency during pregnancy on the background of iron deficiency anemia can be verified morphologically based on quantitative indicators of assessment of the structure of the placental chorionic tree - the percentage of terminal villi should be higher than 43% and the percentage of terminal "specialized" villi lower than 15%.

The purpose of the study is to establish quantitative parameters of cell proliferation and apoptosis in the trophoblast of the chorionic villi in chorioamnionitis and basal deciduitis combined with iron-deficiency anemia in gravidas by means of immunohistochemical method. Materials and methods. 198 placentas were examined. The immunohistochemical procedure was performed using primary antibodies against Ki-67 and Bax antigen with imaging by a polymer system with diaminobenzidine dye. The number of Ki-67-positive nuclei of the chorionic villi trophoblast was counted, and for the Bax antigen, the optical density of the immunohistochemical staining was measured by means of microdensitometric method. Comparison of differences in mean trends was performed using the odd Student’s two-sided t-test (p≤0.05). Results and discussion. The number of Ki-67-positive trophoblast nuclei in acute chorioamnionitis with iron-deficiency anemia in gravidas was 56±3.8 ‰, and the relative units of optical density of immunohistochemical staining for protein Bax – 0.234±0.0012, in chronic – 59±3.6 ‰ and 0.2, respectively. The number of Ki-67-positive nuclei of the chorionic villi trophoblast was counted. Placentas with acute as well as chronic chorioamnionitis and basal deciduitis showed even higher averages (p <0.001). In acute basal deciduitis in anemia, the number of Ki-67-positive trophoblast nuclei was 56±3.2 ‰, the average optical density of immunohistochemical staining for protein Bax – 0.236±0.0016, in chronic – 57±3.7 and 0.249±0.0015, respectively. It should be noted that in chronic chorioamnionitis and basal deciduitis, these rates were higher than in acute. With the same regularity the average indicators of optical density of immunohistochemical staining on protein Bax in a trophoblast of chorionic villi at comorbid iron-deficiency anemia concerning an inflammation without anemia increase. We have shown that proliferative activity in iron-deficiency anemia varies with gestational age and placental prematurity, but iron-deficiency anemia in gravidas and chorionic tree maturation both individually and in combination lead to the intensification of these processes. We obtained a justification for the arithmetic mean thickness and volume of the placenta relative to observations of placenta with inflammation without anemia in this comorbid pathology. Conclusion. Iron-deficiency anemia in gravidas leads to the intensification of proliferative processes and Bax-dependent apoptosis in the trophoblast of the chorionic villi of the placenta relative to the placenta from physiological pregnancy. In acute as well as in chronic chorioamnionitis and basal deciduitis, the proliferative activity and apoptotic processes in the trophoblast of the chorionic villi of the placenta increase, while comorbid iron-deficiency anemia in gravidas intensifies only the processes of Bax-dependent apoptosis

Background. In Ukraine among perinatal losses, a high proportion of stillbirth remains, the level of which depends on many factors, including the presence of somatic and genital pathology in a woman, pathological conditions during pregnancy, including eclampsia (PE), iron deficiency anemia of pregnant women (IDA), chorioamnionitis (CA). These conditions can be combined with each other, which increases the risk of fetal death during pregnancy or childbirth. Objective. To conduct a somatic and gynecological diseases, complications of pregnancy in pregnant women with preeclampsia (PE), iron deficiency anemia (IDA) and chorioamnionitis (CA), whose pregnancy ended in ante-intrapartum fetal death at 30-40 weeks of gestation. Methods. We investigated 58 cases of stillbirth at 30-40 weeks of gestation from pregnant women with PE (n = 16), IDA (n = 16), CA (n = 26) on the basis of the Communal non-profit enterprise "City Perinatal Center "Kharkov. The clinical data of the mothers, the protocols of the pathological examination of the placenta were studied. Results. Based on the study, it was found that in women whose pregnancy was complicated by PE and IDA, the most frequent types of somatic pathology were hypertensive disorders (32% and 12.5%, respectively) and chronic diseases of the digestive system. (25% and 12.5%, respectively), among gynecological diseases, uterine leiomyoma and endocervicosis were more common, among complications of pregnancy and childbirth - premature birth (50% each, respectively) pathology of the placenta (50% and 68.8%, respectively) and disorders of the content amniotic fluid (31.3% and 18.8%, respectively).The extragenital pathology in pregnant women with CA was presented with the infectious diseases (30.7%), an acute respiratory viral infections (19.2%), the cardiovascular pathology (11.5%), and the chronic inflammatory diseases of various localization (7.6%). The most frequency gynecological pathology were inflammatory genital diseases (23.21%). The pregnancy and labor were often complicated with the placental pathology (50%), premature birth (38.5%), preeclampsia (19.2%), and anemia (19.2%). During pregnancy, placental dysfunction diagnosed only in 31.3% of cases with PE, 25% with IDA and 3.8% with CA, but in pathological examination, morphological signs of placental insufficiency recorded in almost every case of all groups. Conclusion. In pregnancy, aggravated by PE, IDA or CA, the presence of extragenital pathology, gynecological diseases, and other complications of pregnancy were additional factors that increased the severity of placental insufficiency and fetal hypoxia, which was the cause of its death. Timely diagnosis of placental dysfunction and the implementation of therapeutic measures aimed at reducing the associated negative impact on the fetus can help reduce perinatal mortality.
