Placental Dysfunction

According to recent studies, in the vitamin D deficiency state (VDD), pregnancy can be complicated and the optimal level of VD in the blood is one of the conditions for the realization of reproductive potential. The objective: the possibility to preventing calcitriol-associated pregnancy complications by the correcting VD deficiency at the preconception period. Materials and methods. 57 women with VDD were examined. A history of all women had a pregnancy complicated by placental dysfunction (PD); 27 of them were observed from the preconception period (main group – IA) and 30 – from the 1st trimester of pregnancy (comparison group – IB). The VD status by the blood level of the 25-hydroxyvitamin D by ELISA was determined. Women of both groups, in addition to the vitamin-mineral complex (VMC) were prescribed supplementation colecalciferol at a dose of 4.000 IU per day. Pregnant women of both groups received VMCs up to 16 weeks. After optimizing the level (3–4 months), women continued to take VD at a dose of 2.000 IU per day throughout pregnancy. Results. At the initial study, the VD level was 15.72±2.59 ng/ml in ІА and 16.1±1.99 ng/ml in ІВ group (U=883; p>0.05); after treatment increased to 38.31±3.29 ng/ml and 36.13±2.99 ng/ml (U=900; p>0.05). In group IA, the course of pregnancy was characterized by a lower frequency of complications: PD was diagnosed in 22.2% in group IA and 50% in group IB (F=0.0001; p<0.01); fetal distress in 3.7% and 10% (F=0.16; p<0.05): signs of amnionitis – in 18.5% and 33.3% (F=0.035; p<0.05); placental hypertrophy or hypotrophy – in 7.4% and 36.7% (F=0.00001; p<0.01), preeclampsia in 3.7% and 6.7% of women (F=0,54; p<0.05). The frequency of cesarean section in the comparison group was significantly higher (40% VS 25.9%, F=0.034; p<0.05). Conclusions. During pregnancy, which occurred in conditions of VDD, the frequency of some pregnancy complications, including preeclampsia, the threat of miscarriage, placental dysfunction was in 2–4 times higher than in women with optimized VD status. One of the directions of the individual management plan for women with a negative obstetric history can be the determination of the level of VD in the blood and correction of the VDD at the preconception period. This approach is a pathogenetically substantiated and promising direction for the prevention of some pregnancy complications and improvement of perinatal outcomes.

The objective: depression of frequency of perinatal pathology at women with decompensation form of placental dysfunction by improvement of the main diagnostic and treatment-and-prophylactic actions. Patients and methods. 154 pregnant women in gestation term from 22 to 40 weeks were surveyed. Depending on features of course of pregnancy and families of all surveyed it was divided into 4 groups. The group of the retrospective analysis was made by 45 pregnant women with decompensation placental dysfuction, the group of prospective research included 109 pregnant women of whom the main group was made by 38 women with decompensation form of placental dysfunction, the group of comparison included 47 pregnant women with the compensated form of placental dysfunction. The control group was made by 24 pregnant women with the uncomplicated course of pregnancy and labors. The complex of the conducted researches included clinical, ehografical, dopplerometrical, laboratory, morphological and statistical methods. Results. Use of advanced algorithm of diagnostic and treatment-and-prophylactic actions allows to increase efficiency of diagnostics of decompensation form of placental dysfunction for 33.3%, and rational tactics of a delivery leads to depression of perinatal pathology for 22.7%. Conclusion. Decompensation placental dysfuction is one of the main reasons for perinatal mortality and a case rate at the present stage. Use of the algorithm of diagnostic and treatment-and-prophylactic actions improved by us allows major factors of risk of this complication and the indication for change of tactics and delivery times.

The objective: frequency decrease perinatal pathologies at women after ART on the basis of studying clinical-ehografical, endocrinological, biochemical, dopplerometrical, cardiotokografical and morphological researches, and also improvement of algorithm of diagnostic and treatment-and-prophylactic actions. Patients and methods. The work basis is made spent by us from 2012 on 2015 by complex inspection of 300 pregnant women from which 250 were after ART and 50 – firstlabours which pragnency without ART, and also their newborns. For the decision of an object in view of research spent to two stages. At 1 stage spent prosperctive research which included 150 pregnant women: з them 100 women pregnancy at which has come out ART (1 group) and 50 healthy women (control group). At 2 stage spent prospective randomization in which result of patients after ART have divided on two equal groups by therapy principle: 2 basic group - 75 pregnant women after ART at which used the algorithm improved by us; 3 group of comparison - 75 pregnant women after ART which have been spent on the standard treatment-and-prophylactic actions. Results. The results suggest that women after using ART is a high frequency of reproductive losses in the first trimester (10.0%), 3.0% of spontaneous abortion from 16 to 22 weeks, and 3.0% "early" premature delivery (22 to 28 weeks of pregnancy). The frequency of violations of the functional state of placenta in women after using IVF is 63.0%, which is the main cause of high levels of perinatal losses (40.0 ‰), and delivery by cesarean section (96.0%). Placental dysfunction in women after using ART characterized by retrohorialnyh hematoma (21.0%); size mismatch fruit (30.0%) and hypertonicity of the uterus (73.0%) against changes in fruit-placental blood flow - increased resistance index in umbilical artery and increased vascular resistance in the uterine arteries. Endocrinological and biochemical changes in placental dysfunction in women after using IVF starting from 28 weeks of pregnancy and are in significant reduction in progesterone, placental b1-microglobulin, B2-microglobulin of fertility and trophic в-glycoprotein. Conclusion. The received results: use of the algorithm of diagnostic and treatment-and-prophylactic actions improved by us allows to lower frequency of spontaneous interruption of pregnancy till 22 weeks – from 13.0% to 5.7%; «early» premature birth – from 3.0% to 1.0%; placentary dysfunction from 63.0% to 40.6%; cesarean sections – from 96.0% to 56.5%, and also perinatal losses – from 40.0‰ to 16.2‰.

The objective: studying of features of the psychoemotional and vegetative status at women with placental dysfunction at the previous pregnancy. Patients and methods. Complex clinical-laboratory examination of 89 women, from which was conducted: control group – 42 obstetrically and somatically healthy multipara, delivery through natural patrimonial ways; І group – 47 women with placental dysfunction at the previous pregnancy. Carried out a cardiointervalografia by means of a single-channel electrocardiograph and used a scale questionnaire of a condition of the pregnant woman. Results. It is established that regulation of cardiac rhythm at women at the previous pregnancy happens to placental dysfunction in the conditions of an autonomous contour which controls normal work of heart and vegetative nervous system. Further, there is an expressed strain of regulatory mechanisms that is shown by centralization of management of cardiac activity and sharp rising of activity of sympathetic nervous system. At the final stage influence of the central contour considerably decreases and patofunctionale vegetative equilibrium is again formed. Conclusions. The received results need to be considered when developing tactics of conducting pregnancy at these women. Key words: placental dysfunction, vegetative and psychological status.

The article presents the predictors of placental dysfunction on the early stage of pregnancy. The objective: the search for prognostic markers and criteria for the occurrence of placental insufficiency in the early stages of the gestational process to optimize the pregnancy and labor with improved perinatal outcomes. Patients and methods. To solve this goal in the period from 2013 to 2015 were conducted a comprehensive survey of 334 pregnant women, which depending on the peculiarities of pregnancy and childbirth were divided into groups. The control group consisted of 236 pregnant women with uncomplicated gestational period, no morphological signs of placental dysfunction. The study group included 98 patients with a complicated pregnancy who had revealed violations of the fetal-placental relations, which was confirmed by morphological examination of the placenta in the postpartum period. Results. It was found that pregnant women with placental insufficiency in the first trimester of pregnancy have higher levels of interleukin-1B (IL-1v) and interleukin-3 (IL-3) in comparison with physiological pregnancy, as well as there is a direct significant correlation between IL-1v and pulsative index (PI) in the spiral (r=0.84) and uterine artery (r=0.77), and the inverse correlation between the level of IL-3 and PI in the terminal branches of the umbilical artery (r=-0.69). Verified an inverse relationship between the concentration of endothelin-1, the level of vascular endothelial growth factor (r=-0.87) and placental growth factor (r=-0.73), and also a direct link between the content of endothelin-1 and PI in spiral arteries (r=0.89), uterine artery (r=0.83) and the terminal branches of the umbilical artery (r=0.79). Conclusion. Thus, it is proven that early predictors of placental dysfunction can be considered the concentration of endothelin-1, vascular endothelial growth factor, placental growth factor, interleukin-1, interleukin-3, and the indices of pulsative index. Key words: placental dysfunction, predictors, endothelin-1, vascular endothelial growth factor, placental growth factor, interleukin, pulsative index.

Biomarkers for placental dysfunction are currently lacking. We recently identified SPINT1 as a novel biomarker; SPINT2 is a functionally related placental protease inhibitor. This study aimed to characterise SPINT2 expression in placental insufficiency. Circulating SPINT2 was assessed in three prospective cohorts, collected at the following: (1) term delivery (n = 227), (2) 36 weeks (n = 364), and (3) 24–34 weeks’ (n = 294) gestation. SPINT2 was also measured in the plasma and placentas of women with established placental disease at preterm (<34 weeks) delivery. Using first-trimester human trophoblast stem cells, SPINT2 expression was assessed in hypoxia/normoxia (1% vs. 8% O2), and following inflammatory cytokine treatment (TNFa, IL-6). Placental SPINT2 mRNA was measured in a rat model of late-gestational foetal growth restriction. At 36 weeks, circulating SPINT2 was elevated in patients who later developed preeclampsia (p = 0.028; median = 2233 pg/mL vs. controls, median = 1644 pg/mL), or delivered a small-for-gestational-age infant (p = 0.002; median = 2109 pg/mL vs. controls, median = 1614 pg/mL). SPINT2 was elevated in the placentas of patients who required delivery for preterm preeclampsia (p = 0.025). Though inflammatory cytokines had no effect, hypoxia increased SPINT2 in cytotrophoblast stem cells, and its expression was elevated in the placental labyrinth of growth-restricted rats. These findings suggest elevated SPINT2 is associated with placental insufficiency.
