The purpose of the study was TO analyze the fetoplacental complex hormone levels and changes in their dynamics in pregnant women with miscarriage and the impact of these features on the subsequent course of pregnancy. Hormone levels were determined at different stages of gestation in 50 healthy women with a physiological course of pregnancy (control group) and 50 pregnant women with a history of miscarriage (main group). The women of the main group had a significantly slower rate of increase in hormones and a lag in quantitative indicators than the control group. The estradiol level indicators were 4.1 times (76.0%) and 2.89 times (65.5%) lower in women with miscarriage in the embryonic and late fetal period, respectively, compared to healthy women. Indicators of the level of placental lactogen and chorionic gonadotropin in the embryonic period in women with miscarriage were lower by 39.1% and 50.9%, respectively, compared to healthy women. In the late fetal period, the level of these hormones was lower by 72.9% and 35.4%, respectively. In the embryonic and late fetal periods, progesterone levels were lower by 67.4% and 68.4%, respectively, compared to the control group. The data obtained are evidence of a pronounced hormonal abnormality of the placenta, and hence a marker of fetoplacental dysfunction, which on the background of miscarriage develops at the early stages and continues to progress with the course of pregnancy.

The aim: The aim of the study was to assess the peculiarities of the formation and development of the fetoplacental system, to study the structures of the embryo, gestational sac, chorion in pregnant women with miscarriage. Materials and methods: A comprehensive ultrasound examination of 50 pregnant women was carried out in the period from 5 to 16 weeks of pregnancy, of which 25 - with a history of miscarriage (main group), and 25 - with an unremarkable medical history (control group). Results: We have identified the following echographic markers of adverse course and outcome of pregnancy in women with miscarriage in embryonic and early fetal periods:- lag of CRL of an embryo by 2 weeks and more at ultrasound examination in terms up to 9 weeks of gestation;- corporal or basal (near the stem of the embryo body) location of chorionic detachment with the formation of retrochorial hematoma with a volume of more than 25 ml;- pronounced progressive decrease in the volume of the gestational sac and amniotic cavity;- pronounced polyhydramnios with the presence of a coarse echopositive suspension in the amnioticcavity. The likelihood of spontaneous miscarriage and the formation of placental dysfunction is higher with the simultaneous detection of 2 or more echographic markers. Conclusions: Ultrasound examination is necessary to assess the echographic parameters of the formation and development of the embryo and extraembryonic structures in the first trimester with a history of miscarriage in order to the subsequent choice of rational tactics of pregnancy management.

Pregnancy miscarriage is a consequence of many factors. The aim of the study was to analyze the effect of miscarriage gene on embryometric, ultrasound, hormonal, immunological parameters in pregnant women, and to evaluate its prognostic value. The main group includes 31 pregnant women who had clinical signs of miscarriage in current or previous pregnancy. The control group consists of 32 healthy pregnant women whose clinical-paraclinical parameters served as a control to compare the data of the pregnancy survey of the main surveillance group. A general clinical examination and a special obstetrical examination (complaints, anamnesis, general medical examination, obstetric examination), biochemical studies (determination of hormones of the fetoplacental complex in blood serum of pregnant women), ultrasound, immunological studies, histological studies of the placenta, molecular genetic study A1166C polymorphism of the AGTR1 gene were made. In the course of the research, the genetic determinism of miscarriage was discovered. The polymorphism of the A1166C of the AGTR1 gene was considered as a prognostic marker of miscarriage in early gestational term and preeclampsia in the second half of pregnancy. A reliable marker of abortion was the maternal genotype 1166AC for the genome AGTR1. The risk of occurrence of clinical manifestations of abortion increased five times. At simultaneous influence of all prognostic factors the risk of abortion increased 6,25 times. Detection of genetic markers of pregnancy miscarriage will allow early correction of this pathology and prevent perinatal loss.

Introduction. The article represents the results of the study of the placental hormone level during the early stages of gestation (5-20 weeks). The aim of the study. To analyze the level of hormones of the fetoplacental complex in pregnant women with miscarriage, along with the dynamics of changes in these indicators. To evaluate the features of the hormonal status of women during law-risk pregnancy and  miscarriage in history and the impact of these features on the functional state of the fetoplacental complex and the subsequent course of pregnancy. Material and methods. We examined 30 somatically healthy women with a physiological course of pregnancy (the control group) and 30 pregnant women with a miscarriage in history (the main group). Research results. It was found that the content of estradiol, chorionic gonadotropin and placental lactogen in the blood plasma of pregnant women of the main group was significantly lower during the entire gestational period compared to the control group. Estradiol levels in pregnant women with miscarriage were 4.2 times lower than in healthy pregnant women. Placental lactogen levels in the main group of pregnant women were 6.1 times lower, and chorionic gonadotropin - 3.7 times lower compared with the control group. There was also a significant backlog in the growth of hormone levels as the pregnancy progressed. In its turn it indicates the development of placental dysfunction in women with a miscarriage in history in the early stages of gestation. Conclusions. As a result of the described changes there is a violation of the first wave of cytotrophoblast invasion and, as a consequence, incomplete gestational remodeling of segments of spiral arteries. The walls of blood vessels are not completely replaced by fibrinoid and the formed placental vessels do not provide a constant flow of arterial blood into the intervillous space. As a result, the uterine-placental area and the formed placenta are not ready to meet the needs of the developing fetus. In the future, this can lead to perinatal losses.
