BACKGROUND Earlier studies indicate that altered angiogenesis at birth is associated with poor birth outcome in women with preeclampsia. Now, we hypothesize that the progressive gestation dependant changes in markers of angiogenesis will be more useful to predict birth weight early even in a normotensive pregnancy. This study for the first time examines the association of gestation dependant changes in the levels of maternal angiogenic factors in addition to their levels in cord with birth weight. METHOD Ninety two pregnant women were followed at three different time points: 16-20 weeks, 26-30 weeks and at delivery during pregnancy. Plasma levels of angiogenic and anti angiogenic factors were determined by commercial enzyme-linked immunosorbent assay (ELISA) kits. RESULTS Maternal plasma VEGF levels increased (p<0.01) till the second time point and decreased (p<0.05) up to delivery while plasma sFlt-1 levels increased (p<0.01) at delivery. PlGF levels peaked (p<0.01) at second time point and decreased (p<0.01) at delivery. Cord plasma VEGF levels were higher (p<0.01) and sFlt-1 levels were lower (p<0.01) as compared to maternal values at all time points. Maternal plasma VEGF levels at first time point and PlGF levels at delivery were positively (p<0.05 and p<0.01 respectively), while sFlt-1/PlGF ratio at delivery was negatively associated (p<0.05) with birth weight. CONCLUSION Levels of pro- and anti-angiogenic factors may be differentially regulated across gestation. Maternal VEGF levels at early gestation (16-20 weeks) may be predictive of birth weight in healthy term pregnancies.

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.

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.

Abstract 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 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.

Maternal nutrition, especially LCPUFA, is an important factor in determining fetal growth and development. Our earlier cross sectional study reports lower docosahexanoic acid (DHA) levels at the time of delivery in mothers delivering low birth weight (LBW) babies. This study was undertaken to examine the role of the maternal omega-3 and omega-6 fatty acid profile across the gestation in fetal growth. This is a hospital based study where women were recruited in early gestation. Maternal blood was collected at 3 time points, i.e., T1 = 16th–20th week, T2 = 26th–30th week and T3 = at delivery. Cord blood was collected at delivery. At delivery, these women were divided into 2 groups: those delivering at term a baby weighing >2.5kg [Normal birth weight (NBW) group] and those delivering at term a baby weighing <2.5kg [LBW group]. The study reports data on 111 women recruited at T1, out of which 60 women delivered an NBW baby at term and 51 women delivered an LBW baby at term. Fatty acids were analysed using gas chromatography. At T1 of gestation, maternal erythrocyte DHA levels were positively (p<0.05) associated with baby weight. Maternal plasma and erythrocyte arachidonic acid and total erythrocyte omega-6 fatty acid levels at T2 were higher (p<0.05 for both) in the LBW group. Total erythrocyte omega-3 fatty acid levels were lower (p<0.05) while total erythrocyte omega-6 fatty acid levels were higher (p<0.05) in the LBW group at delivery. Our data demonstrates the possible role of LCPUFA in the etiology of LBW babies right from early pregnancy.

INTRODUCTION Our recent study in preeclampsia indicates differential oxidative stress in various regions of the placenta. Oxidative stress is known to influence neurotrophin levels. We therefore hypothesize that placental regional differences in oxidative stress will also lead to differences in neurotrophin levels. METHODS The current study examines the levels of neurotrophins, brain derived neurotrophic factor (BDNF) and nerve growth factor (NGF) in different regions of the placenta in 50 normotensive control women and 47 women with preeclampsia (21 delivering at term and 26 delivering preterm). Placentae were collected from four different regions: central maternal (CM), central fetal (CF), peripheral maternal (PM) and peripheral fetal (PF). RESULTS BDNF levels were higher in CF region as compared to CM (p < 0.01), PM (p < 0.01) and PF (p < 0.05) regions of the placenta in the control group. There was no regional change in NGF levels in any of the groups. Analysis between groups indicated higher NGF levels in CM (p < 0.01), PM (p < 0.05) and PF (p < 0.01) regions of preterm preeclampsia group as compared to control. Negative association of NGF levels in CM, CF and PM regions with baby weight and in CF, PM and PF regions with baby length was observed. NGF levels in all four regions were positively associated with systolic blood pressure. DISCUSSION Our data indicates regional differences in levels of BDNF only in normotensive control but not in preeclampsia group. Higher NGF levels in preterm preeclampsia may be a response to increased oxidative stress. This may have implications for altered placental development in preeclampsia.

Maternal long chain polyunsaturated fatty acids (LCPUFA) play a key role in fetal growth and development. This study for the first time examines the maternal and cord LCPUFA levels in preeclamptic mothers delivering male and female infants. In this study 122 normotensive control pregnant women (gestation≥37 weeks) and 90 women with preeclampsia were recruited. Results indicate lower maternal plasma docosahexaenoic acid (DHA) levels (p<0.05) in women with preeclampsia delivering male babies as compared to normotensive control women delivering male babies. Similarly, cord nervonic acid levels were lower (p<0.01) in women with preeclampsia delivering male babies as compared to normotensive control group. However, cord nervonic acid levels were comparable in women with preeclampsia and normotensive control women delivering female babies. This data suggests that male babies born to mothers with preeclampsia may be at an increased risk of developing neurodevelopmental disorders as compared to female babies. Future studies need to follow up both male and female children born to mothers with preeclampsia since altered levels of LCPUFA at birth may have differential implications for the growth and development.

Abstract Objective: The present prospective study examines the levels of maternal plasma folate, vitamin B12 and homocysteine in normotensive control (NC) women and women with preeclampsia (PE) from early pregnancy till delivery. Methods: The present study includes 126 NC and 62 PE women. Maternal blood was collected at 3 time points during pregnancy (T1 = 16th–20th weeks, T2 = 26th–30th weeks and T3 = at delivery). Levels of folate, vitamin B12 and homocysteine were estimated by the chemiluminescent microparticle immunoassay technology. Results: Maternal plasma folate levels were similar between NC and PE women at all the time points across gestation. Maternal plasma vitamin B12 levels were significantly higher in PE (p < 0.05) as compared with NC at T2. Maternal plasma homocysteine levels were higher in PE as compared with NC at all the time points, i.e. T1, T2 (p < 0.05 for both) and T3 (p < 0.01). Conclusion: Our results indicate that higher homocysteine levels exist in women with PE from early pregnancy and continue till delivery.
