Our previous cross-sectional studies have shown altered proportions of long chain polyunsaturated fatty acids (LCPUFA) in preeclampsia (PE) at the end of pregnancy when the pathology has already progressed. The present longitudinal study for the first time reports fatty acid proportions from 16th week of gestation till delivery and placental transport in PE. This is a hospital based study where women were recruited in early pregnancy. Maternal blood was collected at 3 time points i.e. T1=16-20th week, T2=26-30th week and T3=at delivery. Cord blood and placenta were collected at delivery. This study reports data on 140 normotensive control (NC) and 54 PE women. In PE we report lower proportions of DHA in maternal plasma at T1, cord plasma and placenta ( p<0.05 for all). The mRNA levels of placental 5 desaturase, fatty acid transport proteins -1, -4, were lower ( p<0.05 for all) in PE. There was also a positive association between cord and maternal plasma DHA and total omega-3 fatty acids at T1. This study demonstrates that women with PE have lower fatty acids stores at 16-20th week of gestation and lower placental synthesis and transport. It is likely that supplementation of omega-3 fatty acids during the 16-20th week of gestation may help in improving fatty acid status in infants born to mothers with PE. © 2014 Elsevier Ltd.

The present prospective study examines proportions of maternal erythrocyte fatty acids across gestation and their association with cord erythrocyte fatty acids in normotensive control (NC) and preeclamptic pregnancies. We hypothesize that maternal fatty acid status in early pregnancy influences fetal fatty acid stores in preeclampsia. 137 NC women and 58 women with preeclampsia were included in this study. Maternal blood was collected at 3 time points during pregnancy (16-20th weeks, 26-30th weeks and at delivery). Cord blood was collected at delivery. Fatty acids were analyzed using gas chromatography. The proportions of maternal erythrocyte α-linolenic acid, docosahexaenoic acid, nervonic acid, and monounsaturated fatty acids (MUFA) (p < 0.05 for all) were lower while total n-6 fatty acids were higher (p < 0.05) at 16-20th weeks of gestation in preeclampsia as compared with NC. Cord 18:3n-3, 22:6n-3, 24:1n-9, MUFA, and total n-3 fatty acids (p < 0.05 for all) were also lower in preeclampsia as compared with NC. A positive association was observed between maternal erythrocyte 22:6n-3 and 24:1n-9 at 16-20th weeks with the same fatty acids in cord erythrocytes (p < 0.05 for both) in preeclampsia. Our study for the first time indicates alteration in maternal erythrocyte fatty acids at 16th weeks of gestation which is further reflected in cord erythrocytes at delivery in preeclampsia. © 2015 AOCS.

Preeclampsia (PE) is a major pregnancy complication of placental origin which leads to adverse pregnancy outcome. Brain derived neurotrophic factor (BDNF) is suggested to promote trophoblast growth and regulate placental and fetal development. This study for the first time examines the levels of maternal plasma BDNF at various time points during gestation, cord plasma and placental BDNF levels and their association with birth outcome in women with PE. Normotensive control (NC) women (n= 89) and women with PE (n= 61) were followed at three different time points [16-20 weeks (T1), 26-30 weeks (T2) and at delivery (T3)]. Maternal blood at all time points and cord blood was collected. Results indicate that maternal BDNF levels at T1 (p= 0.050) and T3 (p= 0.025) were lower in women with PE than in NC women. Cord BDNF levels at delivery in women with PE were lower (p= 0.032) than those in NC women. Placental BDNF gene expression was also lower (p= 0.0082) in women with PE than in NC women. Our data suggests that BDNF plays an important role in the development of the materno-fetal-placental unit during pregnancy. Alteration in the levels of BDNF during pregnancy may be associated with an abnormal development of the placenta resulting in PE. © 2014.

Our earlier studies of preeclampsia (PE) at delivery have demonstrated the alteration of one carbon cycle, reduced placental omega 3 fatty acids, altered circulating levels of angiogenic factors and differential placental gene-specific methylation patterns of angiogenic factors. This study was undertaken to examine changes in the levels of angiogenic factors and angiotensin II type 1 receptor autoantibodies (AT1-AAs) throughout gestation, from early pregnancy until delivery, in women with PE and to examine their association with cord angiogenic factors, blood pressure and infant weight. A total of 81 pregnant women (46 normotensive and 35 with PE) were followed at three different time points during pregnancy: 16-20 weeks (T1), 26-30 weeks (T2) and at the time of delivery (T3). The plasma levels of angiogenic factors and AT1-AAs were determined in the maternal and cord plasma by commercial enzyme-linked immunosorbent assay kits. Maternal plasma levels of vascular endothelial growth factor (VEGF) and placental growth factor (PlGF) were lower (P<0.05 for both), whereas soluble fms-like tyrosine kinase-1 (sFlt-1; P<0.05) and the sFlt-1/PlGF ratio (P<0.01) were higher in early pregnancy in the PE group. Maternal plasma AT1-AA levels were higher (P<0.05) at T2 in women with PE. Cord plasma VEGF and soluble kinase insert domain receptor (sKDR) levels were lower (P<0.01 and P<0.05, respectively), whereas AT1-AA levels were higher (P<0.05) in the PE group. Maternal plasma VEGF levels in early pregnancy were positively associated with systolic blood pressure, whereas the sFlt-1/PlGF ratio at T2 was negatively associated with infant weight in the PE group. Low levels of proangiogenic factors (VEGF and PlGF) and high levels of AT1-AAs and antiangiogenic factors (sFlt-1 and sFlt-1/PlGF ratio) are present in the maternal circulation during early gestation in women with PE. © 2014 The Japanese Society of Hypertension.

To analyze the relationship between first-trimester levels of pregnancy-associated plasma protein A (PAPP-A) and small-for-gestational-age (SGA) neonates and preterm births, and to assess predictive utility for these events.A prospective study was conducted among women undergoing first-trimester screening between January 1, 2012, and December 31, 2013, at two centers in Pune, India. Serum PAPP-A levels, pregnancy course, and outcome were assessed.Overall, 1474 women were included. An association was found between the lowest quintile of PAPP-A levels (<0.4 multiples of median) for both SGA (<10th centile; 20.9% of cases in this PAPP-A quintile) and preterm birth (<37weeks; 15.8%). Women in the lowest quintile of PAPP-A concentration had a significantly increased risk of SGA (<10th centile) than did those with higher concentrations (adjusted odds ratio 2.92, 95% confidence interval 2.00-4.27). Their risk of preterm birth (<37weeks) was also increased (adjusted odds ratio 1.84, 95% confidence interval 1.25-2.72). The predictive sensitivities of the lowest quintile of PAPP-A were 35.85% for SGA (<10th centile) and 27.92% for preterm birth (<37weeks).Low levels of PAPP-A were associated with SGA and preterm births; however, poor predictive sensitivity could restrict clinical utility of this marker when used alone.

Preeclampsia (PE) is a pregnancy-specific disorder, defined as new onset of maternal hypertension and proteinuria after 20 weeks of gestation. Our earlier study has shown increased maternal oxidative stress at delivery to be associated with poor birth outcome in PE. However, these results were observed when the pathology had progressed and may have been secondary to the effects of the disorder. To understand the role of antioxidant defense mechanisms in PE right from early pregnancy, in this prospective study, we measured malondialdehyde (MDA), superoxide dismutase (SOD), glutathione peroxidase (GPx) and glutathione (GSH) concentrations in maternal blood at 3 time-points of gestation [16-20 weeks (T1), 26-30 weeks (T2), at delivery (T3)] and in cord blood. Gene expression of SOD and GPx and protein levels of endothelial nitric oxide synthase (eNOS) enzyme were also analyzed in the placenta. MDA levels were higher at T1 (p<0.01) and T2 (p<0.01) in women with PE as compared with control. GPx levels were higher at T3 (p<0.05) while SOD levels were lower at T2 (p<0.05), T3 (p<0.01) and in cord (p<0.01) in PE. GSH levels at T1 (p<0.05) and expression of GPx in the placenta were lower in PE as compared with control. In conclusion, this study demonstrates that women who develop PE exhibit increased oxidative stress right from 16 to 20 weeks of gestation. This may alter placental development and lead to fetal programming of adult non-communicable disease in the offspring.

Preeclampsia (PE) is characterized by hypertension and proteinuria. Improper development of the placenta due to altered angiogenesis is the main culprit in PE. Nerve growth factor (NGF) is an angiogenic factor which is expressed and localized in the placenta. Our earlier cross sectional study has shown altered NGF levels at delivery in women with PE. However, there are no studies on NGF levels in PE early in pregnancy before manifestation of the disease. Thus, there is a need to examine the role of NGF in vascular development during different stages of gestation in PE. A longitudinal study was carried out where pregnant women were enrolled from two major hospitals from Pune, Bharati hospital and Gupte hospital. They were followed at three different time points [16-20 weeks (T1), 26-30 weeks (T2) and at delivery (T3)] during pregnancy and maternal blood at every time point and cord blood at delivery was collected and processed. This study included normotensive women (n=88) and women with PE (n=48). NGF levels were measured from maternal and cord plasma using the Emax Immuno Assay System (Promega). The data was analyzed using the SPSS/PC+ package (Version 20.0, Chicago, IL, USA). Maternal NGF levels did not change at all time points while cord NGF levels were higher (p<0.05) in women with PE. Further, maternal NGF levels were negatively associated with blood pressure while cord NGF levels were positively associated with baby head circumference. Our data suggests that there may possibly be a compensatory role for NGF in the foeto-placental circulation in PE.
