[PMID: 37891883 PMCID: PMC10604113 DOI: 10.3390/antiox12101804] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2023] [Revised: 09/20/2023] [Accepted: 09/23/2023] [Indexed: 10/29/2023] Open
Abstract
BACKGROUND Maternal physiological hypercholesterolemia (MPH) occurs in pregnancy for a proper fetal development. When cholesterol increases over the physiological range, maternal supraphysiological hypercholesterolemia (MSPH) is described, a condition underdiagnosed by a lack of evidence showing its biological and clinical relevance. AIM To determine if MSPH associates with maternal vascular dysfunction, along with changes in the composition and function of maternal HDL leading to increased cardiovascular risk. METHODS This study included 57 women at term of pregnancy in which a lipid profile was determined. RESULTS Maternal total cholesterol (TC) and LDL but not HDL were increased in MSPH women. The isolated HDL from a subgroup of MSPH women had a lower protein abundance and a reduced activity of the antioxidant enzyme PON1; however, an increased antioxidant capacity compared to MPH was observed, along with higher serum levels of α-tocopherol. Moreover, HDL from a subgroup of MSPH women had a lower capacity to induce NO synthesis in endothelial cells compared to MPH. In the circulation, we observed a reduced total antioxidant capacity and augmented levels of soluble VCAM, ApoB, ApoCII, ApoCIII, IL-10, and IL-12p70, as well as the cardiovascular risk ratio ApoB/ApoAI, compared to MPH women. CONCLUSION MSPH women present dysfunctional HDL and increased atherogenic cardiovascular risk factors.

Abstract
Background: Pre-eclampsia (P-EC) is associated with systemic inflammation, endothelial dysfunction and hypercoagulability. The role of extracellular vesicles (EVs) in coagulation disturbances affecting the development and severity of P-EC remains elusive. We aimed to evaluate the concentration of EVs expressing phosphatidylserine (PS) and specific markers in relation to the thrombin and fibrin formation as well as fibrin clot properties, in pregnant women with P-EC in comparison to healthy pregnant women of similar gestational age. Methods: Blood samples of 30 pregnant women diagnosed with P-EC were collected on the morning following admission to hospital and after delivery (mean duration 5 days). The concentration of the PS-exposing EVs (PS+ EVs) from platelets (CD42a+, endothelial cells (CD62E+), and PS+ EVs expressing tissue factor (TF) and vascular cell adhesion molecule 1 (VCAM-1) were measured by flow cytometry. Further phenotyping of EVs also included expression of PlGF. Markers of maternal haemostasis were correlated with EVs concentration in plasma. Results: Preeclamptic pregnancy was associated with significantly higher plasma levels of PS+ CD42a+ EVs and PS+ VCAM-1+ EVs in comparison with normotensive pregnancy. P-EC patients after delivery had markedly elevated concentration of PS+ CD42a+ EVs, CD62E+ EVs, TF+ EVs, and VCAM-1+ EVs compared to those before delivery. Inverse correlation was observed between EVs concentrations (PS+, PS+ TF+, and PlGF+) and parameters of overall haemostatic potential (OHP) and fibrin formation, while PS+ VCAM-1+ EVs directly correlated with FVIII activity in plasma. Conclusion: Increased levels of PS+ EVs subpopulations in P-EC and their association with global haemostatic parameters, as well as with fibrin clot properties may suggest EVs involvement in intravascular fibrin deposition leading to subsequent microcirculation disorders.

Abstract
Pregnancy leads to adaptations for maternal and fetal energy needs. The cardiovascular system bears the brunt of the adaptations as the heart and vessels enable nutrient supply to maternal organs facilitated by the placenta to the fetus. The components of the cardiovascular system are critical in the balance between maternal homeostatic and fetus driven homeorhetic regulation. Since lipids intersect maternal cardiovascular function and fetal needs with growth and in stress, factors affecting lipid deposition and mobilization impact risk outcomes. Here, the cardiovascular components and functional derangements associated with cardiovascular pathology in pregnancy, vis-à-vis lipid deposition, mobilization and maternal and/or cardiac and fetal energy needs are detailed. Most reports on the components and associated pathology in pregnancy, are on derangements affecting the extracellular matrix and epicardial fat, followed by the endothelium, vascular smooth muscle, pericytes and myocytes. Targeted studies on all cardiovascular components and pathological outcomes in pregnancy will enhance targeted interventions.

Abstract
Cytokines and chemokines are potent modulators of brain development and as such, dysregulation of the maternal immune system can result in deviations in the fetal cytokine balance, altering the course of typical brain development, and putting the individual on a "pathway to pathology". In the current study, we used a multi-variate approach to evaluate networks of interacting cytokines and investigated whether alterations in the maternal immune milieu could be linked to alcohol-related and alcohol-independent child neurodevelopmental delay. This was achieved through the measurement of 40 cytokines/chemokines from maternal blood samples collected during the second and third trimesters of pregnancy. Importantly, during the second trimester we identified network enrichment in levels of cytokines including IFN-ɣ, IL-10, TNF-β, TNF-α, and CRP associated with offspring neurodevelopmental delay. However, as elevations in levels of these cytokines have previously been reported in a wide range of neurodevelopmental disorders including autism spectrum disorder and schizophrenia, we suggest that this cytokine profile is likely not disorder specific, but rather may be an indicator of neurodevelopmental delay in general. By contrast, distinct clusters of activated/inhibited cytokines were identified based on maternal alcohol consumption and child neurodevelopmental outcome. Specifically, cytokines including IL-15, IL-10, MDC, and members of the VEGF sub-family were highest in alcohol-consuming mothers of children with neurodevelopmental delay and were identified in both network analyses and examination of individual cytokines, whereas a differential and unique cytokine profile was identified in the case of alcohol-independent child neurodevelopmental delay. We propose that the current findings could provide a critical step towards the development of early biomarkers and possibly interventions for alcohol-related neurodevelopmental delay. Importantly, the current approach could be informative for understanding mechanisms linking maternal immune system dysfunction and adverse child outcomes in a range of other neurodevelopmental disorders.

Abstract
OBJECTIVE The objective of this study was to determine the profiles of maternal plasma soluble adhesion molecules in patients with preeclampsia, small-for-gestational-age (SGA) fetuses, acute pyelonephritis, preterm labor with intact membranes (PTL), preterm prelabor rupture of the membranes (preterm PROM), and fetal death. MATERIALS AND METHODS A cross-sectional study was conducted to determine maternal plasma concentrations of sE-selectin, sL-selectin, and sP-selectin as well as sICAM-1, sVCAM-1, and sPECAM-1 in patients with (1) an uncomplicated pregnancy (control, n = 100); (2) preeclampsia (n = 94); (3) SGA fetuses (in women without preeclampsia/hypertension, n = 45); (4) acute pyelonephritis (n = 25); (5) PTL (n = 53); (6) preterm PROM (n = 24); and (7) fetal death (n = 34). Concentrations of soluble adhesion molecules and inflammatory cytokines (tumor necrosis factor (TNF)-α and interleukin (IL)-8) were determined with sensitive and specific enzyme-linked immunoassays. RESULTS In comparison to women with a normal pregnancy, (1) women with preeclampsia had higher median concentrations of sE-selectin, sP-selectin, and sVCAM-1, and a lower concentration of sL-selectin (all p values < .001); (2) patients with SGA fetuses had higher median concentrations of sE-selectin, sP-selectin, and sVCAM-1 (all p values < .05); (3) patients with a fetal death had higher median concentrations of sE-selectin and sP-selectin (all p values < .05); (4) patients with acute pyelonephritis had higher median plasma concentrations of sE-selectin, sICAM-1, and sVCAM-1 (all p values < .001); (5) patients with preeclampsia and acute pyelonephritis, plasma concentrations of sVCAM-1, sE-selectin, and sP-selectin correlated with those of the proinflammatory cytokines TNF-α and interleukin (IL)-8 (all p values < .05); (6) patients with PTL had a higher median concentration of sP-selectin and a lower median concentration of VCAM-1 (all p values < .05); and (7) women with preterm PROM had lower median concentrations of sL-selectin and sVCAM-1 (all p values < .05). CONCLUSIONS The results of this study show that endothelial cell activation/dysfunction reflected by the plasma concentration of sE-selectin is not specific to preeclampsia but is present in pregnancies complicated by SGA fetuses, acute pyelonephritis, and fetal death. Collectively, we report that each obstetrical syndrome appears to have a stereotypical profile of soluble adhesion molecules in the peripheral circulation.

Abstract
BACKGROUND Endothelial cell activation in pre-eclampsia is associated with elevated soluble vascular cell adhesion molecule-1 (sVCAM-1) levels. The objective of the study was to determine whether sVCAM-1 levels in Indonesian women with pre-eclampsia were similar to other ethnic studies and to determine the effects of magnesium sulfate with nifedipine on blood pressure. METHODS A total of 61 pregnant women were admitted, who had normal pregnancy (n = 25) and severe pre-eclampsia (n = 36). Blood sampling was performed at admission to the study, 1 h after placental separation, and 24 h postpartum. sVCAM-1 and blood pressure levels were determined. RESULTS The mean ages in normal pregnancy (n = 25) and in severe pre-eclampsia (n = 36) are 30.0 ± 3.4 years and 27.1 ± 6.1 years, respectively. Significantly elevated sVCAM-1 was seen in pre-eclampsia. No significant variation in sVCAM-1 levels during the study periods was seen in both groups of cohorts. Magnesium sulfate infusion and nifedipine significantly lowered the blood pressure level. CONCLUSION Elevated sVCAM-1 levels were also seen in Indonesian women with severe pre-eclampsia. The placenta may not be the only source of elevated sVCAM-1 and that endothelial dysfunction persists beyond the postpartum period. Magnesium sulfate together with nifedipine significantly lowered blood pressure. The determination of elevated sVCAM-1 in pregnancy as a risk marker for endothelial dysfunction is therefore suggested.

Abstract
PROBLEM To determine whether miR-203 mediates endothelial inflammatory response in preeclampsia. METHOD OF STUDY Maternal vessel miR-203 expression was assessed by in situ hybridization. Suppressor of cytokine signaling-3 (SOCS-3) and ICAM expression was determined by immunostaining. Subcutaneous fat tissue sections from normal and preeclamptic pregnant women were used. miR-203-induced inflammatory response was evaluated by the measurements of IL-6, IL-8, ICAM, and VCAM expression and production and neutrophil adhesion in the endothelial cells (EC) transfected with miR-203 precursor, pre-miR-203. SOCS3 expression was also determined. RESULTS Up-regulation of miR-203 and ICAM expression and down-regulation of SOCS-3 expression were demonstrated in maternal vessel endothelium in preeclampsia. Overexpression of miR-203 resulted in down-regulation of SOCS-3 expression and increases in the production of IL-6, IL-8, ICAM, and VCAM and neutrophil adhesion in ECs. CONCLUSION As miR-203 is an inflammatory microRNA, increased miR-203 production/expression in ECs could diminish an anti-inflammatory activity and increase the endothelial inflammatory response in preeclampsia.

Abstract
OBJECTIVE Endothelial cell (EC) activation with up-regulation of cellular adhesion molecule (CAM) expression is a pathophysiologic feature in preeclampsia (PE). Enhanced peroxynitrite formation in the vasculature of women with PE was also reported. This study was to test whether EC oxidative stress induced by peroxynitrite could up-regulate EC CAM expression, and whether heme oxygenase-1 (HO-1) has protective effects on this peroxynitrite-induced cellular response. METHODS Confluent ECs were stimulated with 3-morpholinosydnonimine-HCl (SIN-1, a peroxynitrite generator) alone or combined with Mn(III) tetrakis (1-methyl-4-pyridyl) porphyrin pentachloride (MnTMPyP, a peroxynitrite scavenger) up to 4 hours. EC surface protein expressions for ICAM, VCAM, P-selectin, and E-selectin were measured by colorimetric assay. ECs were also treated with Sn(IV) mesophorphyrin IX dichloride (SnMP, a HO-1 inhibitor) to determine if HO-1 was involved in the increased CAM expression in stressed cells. Protein and mRNA expressions for HO-1 were determined by Western blot analysis and reverse-transcriptase polymerase chain reaction (RT-PCR). Data are presented as the mean +/- SE and analyzed by analysis of variance (ANOVA). RESULTS Endothelial CAM expressions for VCAM, P-selectin, and E-selectin, but not ICAM, were significantly increased in SIN-1-treated ECs. Protein and mRNA expressions for HO-1 were also up-regulated in cells treated with SIN-1. MnTMPyP blocked both mRNA and protein expressions for HO-1, whereas SnMP only blocked HO-1 protein expression. Both MnTMPyP and SnMP abolished SIN-1-induced up-regulation of VCAM, P-selectin, and E-selectin expression in ECs. CONCLUSIONS Peroxynitrite-induced EC oxidative stress produces differential effects on CAM expression, which may be mediated by HO-1 regulation. Our results suggest that increased peroxynitrite formation in the maternal vasculature may contribute to the increased CAM expression and enhanced neutrophil-endothelial interaction associated with PE.

Abstract
OBJECTIVE The purpose of the current study was to determine whether maternal circulating components could regulate oxidative status of glutathione redox cycle and adhesion molecule expression in endothelial cells (ECs). METHODS Maternal plasma was extracted from venous blood obtained from normal term pregnant women and from women with preeclampsia (PE). Normal and PE pregnancies were defined as American College of Obstetricians and Gynecologists criteria. Confluent ECs were incubated with EC growth medium (EGM) containing 20% plasma from women with normal (n = 8) and PE (n = 8) pregnancies for 4 hours. ECs incubated with EGM only were used as control. EC oxidative status was assessed by measuring cellular glutathione reductase (GR) and glutathione peroxidase (GPx) activities. Adhesion molecule expressions for intercellular adhesion molecule (ICAM), vascular cell adhesion molecule (VCAM), P-selectin, and E-selectin were determined by colorimetric assays detected on EC surface by UV spectrophotometer at OD 450 nm. Data are presented as mean +/- SE and analyzed by analysis of variance (ANOVA). A P value < .05 was set as statistically significant. RESULTS Cellular GR activity was reduced approximately 35% in ECs treated with normal plasma and 70% in ECs treated with PE plasma compared to that in untreated control cells: 0.072 +/- 0.014 (P < .05), 0.039 +/- 0.006 (P < .01), versus 0.117 +/- 0.010 U/mg cellular protein, respectively. In contrast, GPx activity was slightly increased in ECs treated with normal plasma and significantly increased in ECs treated with PE plasma compared to that in untreated control cells: 0.059 +/- 0.005, 0.075 +/- 0.012 (P < .05) versus 0.044 +/- 0.002 U/mg cellular protein, respectively. P-selectin, E-selectin, and VCAM expressions were elevated in cells treated with normal plasma but significantly increased in cells treated with PE plasma compared to those of untreated controls: P-selectin--0.18 +/- 0.03, 0.35 +/- 0.04 versus 0.04 +/- 0.01 OD 450 nm, P < .01; E--selectin-0.06 +/- 0.02, 0.10 +/- 0.02 (P < .05) versus 0.03 +/- 0.01 OD 450 nm; VCAM--0.12 +/- 0.02, 0.16 +/- 0.03 (P < .01) versus 0.08 +/- 0.02 OD 450 nm, respectively. There was no difference for ICAM expression in cells treated with normal or PE plasma compared to controls. CONCLUSIONS These data suggest that endothelial pro- and anti-oxidative status could be directly affected by circulating components during pregnancy. Reduced cellular GR activity and increased GPx activity accompany increased inflammatory reactions in ECs responding to circulating "toxic" factors in preeclampsia.

Abstract
The enzyme heme oxygenase (HO) is an important regulatory molecule present in most nucleated mammalian cells which functions to break down the pro-oxidant molecule heme into three products, carbon monoxide (CO), biliverdin and free iron. The HO system has been associated with many physiologic functions, including vascular tone, regulation of inflammation and apoptosis, angiogenesis and antioxidant capabilities. Deficiencies in HO are associated with several pregnancy disorders, including preeclampsia. With no present cure, this disorder continues to affect 5–7% of all pregnancies worldwide, leading to maternal and fetal morbidity and mortality. Researchers continue to strive for therapeutic potentials and this review will outline the possible use of the HO/CO system as a target treatment/prevention of preeclampsia in the future.

Abstract
Tetrabromobisphenol A (TBBPA) is a widely used flame retardant. Despite the presence of TBBPA in gestational tissues and the importance of proper regulation of inflammatory networks for successful pregnancy, there is no prior study on the effects of TBBPA on inflammatory responses in gestational tissues. The present study aimed to investigate TBBPA activation of inflammatory pathways, specifically cytokine and prostaglandin production, in the human first trimester placental cell line HTR-8/SVneo. TBBPA enhanced release of interleukin (IL)-6, IL-8, and prostaglandin E2 (PGE2), and suppressed TGF-β release in HTR-8/SVneo cells. The lowest effective concentration was 10 μM TBBPA. A commercial immune response PCR array revealed increased expression of genes involved in inflammatory pathways stimulated by TBBPA in HTR-8/SVneo cells. Because proper regulation of inflammatory mediators in the gestational compartment is necessary for normal placental development and successful pregnancy, further investigation on the impact of TBBPA-stimulated responses on trophoblast function is warranted.

Abstract
Background/objective Patients with systemic lupus erythematosus (SLE) are at increased risk for adverse pregnancy outcomes and cardiovascular disease (CVD). The objective of this exploratory study was to investigate the association between a history of adverse pregnancy outcomes and subsequent risk of subclinical CVD assessed by imaging studies and verified clinical CVD events in 129 women with SLE. Methods The occurrence of adverse pregnancy outcomes, specifically pre-eclampsia, preterm birth and low birth weight was ascertained by questionnaire. Subclinical CVD was assessed by coronary artery calcium (CAC) as measured by electron beam CT and carotid plaque measured by B mode ultrasound. Clinical CVD events were verified by medical record review. Logistic regression was used to estimate the association of pregnancy complications with occurrence of subclinical CVD and clinical CVD with a priori adjustment for age, which is associated with CVD and SLE disease duration as a measure of SLE disease burden. Results Fifty-six women reported at least one pregnancy complication while 73 had none. Twenty-six women had at least one pregnancy complicated by pre-eclampsia and were more likely to have a CAC score greater than or equal to 10 (adjusted OR=3.7; 95% CI 1.2 to 11.9), but the presence of plaque was not associated with this pregnancy complication, OR=1.1, (95% CI 0.4 to 2.8). Low birth weight and preterm birth were not associated with CAC or plaque. Conclusions Patients with SLE with a history of pre-eclampsia had a higher rate of subclinical CVD as measured by CAC score. Future studies are needed to confirm the relationship between adverse pregnancy outcomes and subsequent subclinical CVD and clinical CVD events.

Abstract
BACKGROUND Preeclampsia (PE) is one of the most important complications of pregnancy that is associated with significant mortality and morbidity in mother and fetus. Since the etiologic factors in its development are still unclear, we aimed to examine the intercellular adhesion molecule-1 (ICAM-1) gene K469E polymorphism in preeclamptic and control healthy women. MATERIALS AND METHODS Genetic polymorphism was analyzed in 192 PE and 186 healthy control women. PCR-RFLP method was used to identify K469E polymorphism. RESULTS The frequency of KK, KE, and EE genotypes of ICAM-1 gene was not different between PE patients and healthy pregnant women. Whereas, the frequency of KE and EE genotypes was significantly higher in severe PE than mild PE women and control group, and the risk of severe PE was 2.4-fold higher in subjects with KE genotype (OR, 2.4 [95% CI, 1 to 5.9]; P = 0.03) and 3.3-fold higher in subjects with EE genotype (OR, 3.3 [95% CI, 1.2 to 9]; P = 0.015) compared to individuals with KK genotype. CONCLUSION We concluded that KE and EE genotypes of K469E polymorphism could increase risk of severe PE.

Abstract
OBJECTIVE The objective of the study was to examine the associations of maternal plasma levels of 25-hydroxyvitamin D [25(OH)D] with angiogenesis and endothelial dysfunction indicators: soluble fms-like tyrosine kinase-1 (sFlt-1), placental growth factor (PlGF), intercellular adhesion molecule-1 (ICAM-1), vascular adhesion molecule-1 (VCAM-1), and risk of preeclampsia. STUDY DESIGN In this prospective cohort study (n = 697), maternal plasma 25(OH)D levels were measured at 12-18 and 24-26 weeks; sFlt-1, PlGF, ICAM-1, and VCAM-1 levels were measured at 24-26 weeks. RESULTS Maternal PlGF levels were significantly lower in women with 25(OH)D less than 50 nmol/L at 12-18 weeks (median, 449.5 vs 507.9 pg/mL, P = 0.04) and 24-26 weeks (median, 450.4 vs 522.5 pg/mL, P = 0.007). Both maternal 25(OH)D and PlGF levels were inversely associated with the risk of preeclampsia (both P < .05). However, based on a test of interaction, there was no evidence that the association between vitamin D and preeclampsia depended on the level of PlGF. CONCLUSION Maternal vitamin D deficiency is associated with low PlGF levels and increased preeclampsia risk. However, our data do not support the hypothesis that the association between vitamin D deficiency and preeclampsia is mediated by impaired angiogenesis.

Abstract
BACKGROUND Preeclampsia is characterized by hypertension, dyslipidemia, and systemic inflammatory response. The aim of this study was to determine the level of serum level of soluble vascular cell adhesion molecule-1 (sVCAM-1) and high-sensitive C-reactive protein (hsCRP) in preeclampsia and to compare normal pregnant, mild preeclamptic, and severe preeclamptic women. METHODS A cross-sectional study was conducted to determine the plasma concentrations of sVCAM-1 and hsCRP in peripheral blood obtained from normal pregnant (n = 40), mild preeclamptic (n = 37), and severe preeclamptic women (n = 38). A concentration of soluble adhesion molecule was determined with enzyme-linked immunosorbent assay. hsCRP was measured with immunoturbidometric. RESULTS There was significant difference in the means serum hsCRP between normal pregnant women and mild preeclamptic women (P < 0.05). Serum concentration of hsCRP and sVCAM-1 (ng/mL) were significantly higher in severe preeclampsia (P < 0.05) than normal pregnancy. There were also significant differences in hsCRP and sVCAM-1 levels between mild and severe (P < 0.05). There was no difference in the mean sVCAM-1 between normal pregnant and mild preeclamptic women. CONCLUSION We have determined the serum concentration of VCAM-1 and hsCRP in normal pregnancy and preeclampsia. sVCAM-1 is elevated in severe preeclampsia compared with normal pregnancy, and hsCRP is elevated in severe preeclampsia compared with mild preeclampsia and normal pregnancy.

Abstract
PROBLEM To evaluate whether impaired endothelial function and endothelial inflammatory response occur in parallel in the women with preeclampsia. METHOD OF STUDY Venous blood was drawn from normal (n=40) and severe preeclamptic (sPE) (n=40) pregnant women when they were admitted to the L&D Unit and 24 hrs after delivery. Plasma and serum samples were extracted and measured for 6-keto PGF1α and TXB(2) (stable metabolites of PGI2 and TXA2), and intercellular adhesion molecule (ICAM) and vascular cell adhesion molecule (VCAM) by ELISA. Data are analyzed by Mann-Whitney test and paired t-test. The statistical significance is set as P<0.05. Results Plasma 6-keto PGF1α levels were significantly reduced at admission and 24hr after delivery in sPE compared to normal pregnant controls, P<0.01. The ratio of 6-keto PGF1α and TXB(2) was significant less in sPE than that in normal pregnant controls before delivery. There was no significant difference for ICAM and VCAM levels between normal and patients with sPE before and after delivery. CONCLUSION Maternal 6-keto PGF1α levels and the ratio of 6-keto PGF1α and TXB(2) were decreased in patients with sPE compared to normal pregnant controls. In contrast, maternal ICAM and VCAM levels were not different between the two groups. These data suggest that serum ICAM and VCAM levels may not be sensitive inflammatory biomarkers for preeclampsia.

Abstract
OBJECTIVES To evaluate the association between endothelial activation markers in the maternal circulation with nitric oxide (NO) synthesis in human umbilical endothelial cells. STUDY DESIGN This is a case-control study of normal and pre-eclamptic pregnancies. The levels of sE-selectin, soluble vascular cell adhesion molecule 1 (sVCAM-1), and soluble fms-like tyrosine kinase 1 (sFlt-1) were measured by enzyme-linked immunosorbent assay, and histamine-induced NO synthesis was detected by fluorometric examination of the human umbilical vein endothelial cells (HUVECs) isolated from normal and pathological pregnancies. RESULTS Mothers with severe pre-eclamptic pregnancies have premature and smaller babies than mothers with normal pregnancies (P < 0.05); they also have high maternal plasma levels of sVCAM-1 (∼2-fold), sFlt-1 (∼2.5-fold), and lower (∼70%) histamine-stimulated NO synthesis in HUVECs. A positive relationship between systolic blood pressure (SBP) and plasma levels of sE-selectin, sVCAM-1, and sFlt-1 was demonstrated. Moreover, levels of sE-selectin, sVCAM-1, and sFlt-1 were negatively associated with newborn weight (NBW), gestational age at delivery, and NO synthesis. Women with high E-selectin (>63 ng/ml), VCAM-1 (>752 ng/ml), and sFlt-1 (>15204 pg/ml) showed high risk (∼2-fold) for preterm delivery and very preterm delivery, or fetal weight <1500 g (∼1.5-fold) compared with women with low levels. CONCLUSIONS High circulating levels of maternal endothelial dysfunction markers present in pre-eclampsia are associated with decreased NO synthesis in fetal endothelium.

Abstract
In this study we tested whether plasma from preeclamptic women contains factors that can activate endothelial cells in the presence of monocytes in vitro. Plasma from preeclamptic women (n=6), healthy pregnant women (n=6) and nonpregnant women (n=6) was incubated with mono-cultures and co-cultures of human umbilical vein endothelial cells (HUVEC) and monomac-6 monocytes. Reactive oxygen species (ROS) production and ICAM-1 expression were measured using flow cytometry. Whether scavenging of ROS by superoxide dismutase and catalase inhibited HUVEC ICAM-1 expression was also investigated. We found that in HUVEC co-cultured with monomac-6 cells but not in HUVEC cultured alone, ICAM-1 was upregulated after incubation with plasma from preeclamptic women but not plasma from non-pregnant women. Also in co-cultures, monomac-6 ICAM-1 was upregulated by plasma from preeclamptic women, while in both mono- and co-cultures monomac-6 ROS production was upregulated by plasma from pregnant and preeclamptic women, compared with plasma from non-pregnant women. Scavenging of ROS by superoxide dismutase and catalase resulted in a further upregulation of HUVEC ICAM-1 after incubation with plasma from preeclamptic women, compared with incubation without superoxide dismutase and catalase. These results show that endothelial cells in vitro are activated by plasma of preeclamptic women only if they are co-cultured with monocytes. This upregulation appeared not to be due to extracellular ROS production by monocytes or HUVEC, pointing to involvement of other mechanisms. Our data suggest that plasma of preeclamptic women activates monocytes, and that these monocytes subsequently activate endothelial cells.

Abstract
OBJECTIVE The activation of the complement system results in the generation of split products with pro-inflammatory properties. The objective of this study was to determine whether preeclampsia and small-for-gestational age (SGA) are associated with changes in the maternal plasma concentrations of anaphylatoxins C3a, C4a and C5a. METHODS A cross-sectional study was conducted in the following groups: (a) normal pregnant women (n = 134); (b) women who delivered an SGA neonate (n = 53); (c) preeclampsia with (n = 52) and without SGA (n = 54). Maternal plasma anaphylatoxin concentrations were determined by enzyme-linked immunoassay. RESULTS (1) Women with preeclampsia with or without SGA had a significantly higher median plasma C5a concentration than that of normal pregnant women and those with SGA alone (all P < 0.01); (2) women with SGA alone did not have an increase in plasma C5a concentration; (3) in contrast, the median maternal plasma concentration of C4a was lower in women with preeclampsia and SGA than that of those with a normal pregnancy (P = 0.001); (4) no changes in C3a were observed among the study groups. CONCLUSION Preeclampsia is associated with increased plasma concentration of C5a, regardless of the presence or absence of an SGA fetus. In contrast, there was no difference in the plasma C3a, C4a and C5a concentration in patients with SGA.

Abstract
Preeclampsia can have significant impact on health of both mother and fetus. It had been proposed that maternal endothelial cell dysfunction is the key event resulting in the diverse clinical manifestations of preeclampsia and evidence has since accumulated. Research in recent times is indicative of the role of oxidative stress in the endothelial cell dysfunction. Preeclampsia is more common in first pregnancy and studies have further shown an increase in risk of preeclampsia with maternal age. The aim of this study was to explore the status of oxidative stress in higher age-group preeclamptic and normal pregnant mother. The study included 20 normal pregnant women and 60 preeclamptic women. They were allocated into 4 subgroups between ages 20-25, 26-30, 31-35, and 36-40. Erythrocytes were analyzed for the following antioxidant enzymes, i.e., glutathione peroxidase, superoxide dismutase and catalase.Lipid peroxidation product, malondialdehyde, was analyzed to determine oxidative stress. The results showed an increase in oxidative stress, and high magnitude suppression/decrease in antioxidant enzymes activities in erythrocytes with increase in age groups in both preeclamptic and normal pregnant women. This indicates that an increase in the risk of preeclampsia with maternal age could be due to an increase in oxidative stress with age. This further attests to the role of oxidative stress in preeclampsia.

Abstract
Preeclampsia and intrauterine growth restriction are both characterized by placental malfunction. The pathological processes of abnormal trophoblast invasion, partial absence of maternal spiral artery modification, increased apoptosis of trophoblast cells, and placental ischemia are all associated with the release of specific molecules. These proteins, as well as cell-free fetal DNA and RNA might be detected in the maternal peripheral circulation, quantified, and used for early identification and prediction of preeclampsia and intrauterine growth restriction, prior to the appearance of the clinical symptoms. As preeclampsia and intrauterine growth restriction are associated with increased maternal, perinatal, and neonatal morbidity and mortality, early identification of these pregnancy associated complications will permit the design of appropriate preventive measures. In this review a variety of factors reported to be useful as potential markers for early detection of pregnancies at increased risk will be discussed. Molecules associated with the establishment of the placenta and essential in fetal-maternal interactions, like interleukin 2-receptor, insulinlike growth factor-1, and insulinlike growth factor binding protein-1, placenta growth factor, hepatocyte growth factor, inhibin A, activin A, and human chorionic gonadotrophin seem to be the most likely candidates for presymptomatic markers for preeclampsia and/or intrauterine growth restriction. Detection and discrimination of these molecules through the placental RNA in maternal plasma based strategy has become a realistic option.

Abstract
The aim of the study was to examine the expression of adhesion molecules VCAM-1 and ICAM-3 in placental tissue samples and placental bed (maternal decidual tissue) biopsies of pregnancies complicated by pre-eclampsia (PE) and fetal growth restriction (FGR), and to determine whether PE and FGR are associated with an increase in placental apoptosis. We studied placentas and placental bed samples of 49 third trimester pregnancies complicated by FGR (26 with associated PE, 23 without PE) and 25 normotensive healthy pregnant women. Placental apoptosis was assessed by the TUNEL method. Immunohistochemistry was used to assess expression of the VCAM-1 and ICAM-3. There was no significant difference in the staining intensity of VCAM-1 in placentas (p=0.472) and placental bed biopsies (p=0.754) of women delivering appropriate for gestational age and growth restricted fetuses (with and without associated PE). The amount of lymphocytes staining positively with ICAM-3 was significantly higher in both placental and placental bed biopsies of women delivering growth restricted fetuses compared with control pregnancies (p<0.001). Fetal growth restricted pregnancies with associated PE showed higher staining of ICAM-3 in placental compared with placental bed samples (p=0.049). In fetal growth restricted placentas, apoptotic nuclei were more abundant compared with control placentas (p<0.001). Increased expression of ICAM-3 on lymphocyte surface of both maternal and fetal side, suggests lymphocyte overactivation in PE and FGR. Increased placental apoptosis may play an important role in the pathogenesis or sequelae of PE.

Abstract
Endothelial cells (EC) activation is an important inflammatory phenotypic change in the vascular system in women with preeclampsia (PE). In PE, maternal vessel chymotrypsin-like protease (CLP)/chymase expression was increased. Chymase is an inflammatory protease. In this study, we specifically examined whether placental-derived CLP could induce EC activation and whether EC activation is associated with increased cellular protease expression. Human uterine microvascular endothelial cells (UtMVECs) were used. Endothelial activation was determined by endothelial adhesion molecule P-selectin, E-selectin, inter-cellular adhesion molecule (ICAM), and vascular cell adhesion molecule (VCAM) expressions and by extracellular regulated kinase (ERK) activity. Activation of endogenous CLP/chymase associated with ERK phosphorylation was further examined by CLP/chymase short interfering RNA (siRNA). Our results showed that cells treated with PE placental conditioned medium revealed increased P-selectin, E-selectin, and VCAM-1 expressions and increased ERK phosphorylation. Increased endothelial adhesion molecule expression and phosphorylated ERK (pERK) induction could be attenuated or abolished by depletion of CLP in the conditioned medium or by transfecting ECs with CLP/chymase siRNA. These observations suggest that placental-derived CLP/chymase is responsible for inducing endothelial inflammatory phenotypic changes possibly by upregulation of cell adhesion molecule expressions, activation of cellular protease, and induction of ERK phosphorylation. We speculate that activation of endothelial CLP/chymase may directly relate to the increased inflammatory phenotypic changes in the vascular system in women with PE.

Abstract
OBJECTIVE Exaggerated inflammatory response occurs in preeclampsia. Preeclampsia is also associated with elevated endogenous digoxin-like factors (EDLFs). Clinical data suggest that Digibind (a polyclonal sheep digoxin binding Fab fragment) binds to EDLF and may have the potential to attenuate vasoconstriction and other clinical symptoms of preeclampsia. This study was undertaken to determine if Digibind could attenuate increased endothelial inflammatory response induced by tumor necrosis factor-alpha (TNFalpha). STUDY DESIGN Confluent endothelial cells were treated with TNFalpha at different concentrations with or without Digibind in culture. Endothelial adhesion molecule ICAM, VCAM and E-selectin expressions were determined by an immunoassay directly detected on the endothelial surface. Effects of Digibind on TNFalpha-induced extracellular signal-regulated kinase and Na(+)/K(+)-ATPase expressions were also examined. RESULT (1) TNFalpha induced dose-dependent increases in ICAM, VCAM and E-selectin expressions in endothelial cells; (2) Digibind could attenuate and reduce TNFalpha-induced upregulation of endothelial E-selectin, ICAM and VCAM expressions. The blocking effect was in a concentration dependent manner; (3) Digibind had no effects on TNFalpha-induced upregulation of extracellular signal-regulated kinase phosphorylation, but could block TNFalpha-induced downregulation of Na(+)/K(+)-ATPase beta1 expression. CONCLUSION Digibind may exert beneficial effects by preserving cell membrane Na(+)/K(+)-ATPase function and consequently to offset increased inflammatory response in endothelial cells.

Abstract
BACKGROUND Non-dipping pattern of circadian blood pressure in preeclampsia is associated with an increased risk of cardiovascular disease. The pathogenetic mechanisms of this relationship are still unclear. We investigated whether non-dipping in preeclampsia could relate to endothelial activation or damage. METHODS Participants, 20 women with normal pregnancy (mean age 29.9 +/- 5.7 years) and 31 women with preeclampsia (mean age 29.1 +/- 5.1 years), underwent 24-hour ambulatory blood pressure monitoring. Plasma levels of von Willebrand factor (vWf), marker of endothelial damage and of soluble adhesion molecules (sVCAM-1, sICAM-1), and markers of endothelial activation were determined using commercially available enzyme-linked immunoassays. RESULTS Based on whether the nocturnal mean arterial pressure (MAP) relative to the daytime MAP declined by less than 10%, 21 women with preeclampsia were categorized as non-dippers. Compared to healthy pregnant women, patients with preeclampsia showed significantly enhanced levels of vWf (206.9 +/- 40.6 vs. 123 +/- 24 IU/dl;p<0.01) and sVCAM-1 (2,269 +/- 426 vs.1,159.8 +/- 340 ng/ml; p < 0.01). In addition, significantly higher levels of vWf (224.5 +/- 34.9 vs. 170 +/- 23 IU/dl; p < 0.01) and sVCAM-1 (2,405 +/- 421.4 vs. 1,983 +/- 276.7 ng/ml; p = 0.007) were determined, when women with preeclampsia and nocturnal hypertension (non-dippers) were compared to dippers. The results were similar even after adjustment for severity of preeclampsia. In contrast, neither preeclampsia nor dipping status had an effect on sICAM-1 levels. CONCLUSION Nocturnal hypertension in preeclampsia is associated with elevated levels of molecules related to endothelial damage. Endothelial damage is a recognized pathogenetic factor for atherosclerosis and history of preeclampsia is a risk factor for cardiovascular disease. In this context, possible clinical implications of our findings deserve further investigation.

Abstract
OBJECTIVES To examine soluble E-selectin, L-selectin, P-selectin, ICAM-1, and VCAM-1 levels in normotensive and preeclamptic pregnancies. To determine cut-offs useful for preeclampsia early detection. STUDY DESIGN A cohort of nulliparous women was recruited at family medicine clinics in Mexico City. Preeclampsia developed in 75 patients; 125 normotensive controls were matched. Adhesion molecules were assessed in serum obtained at 20 gestation weeks and in third trimester pregnancies. Predictive values and odds ratios for preeclampsia development were calculated with the 20 gestation week results. Threshold values were selected based on ROC curves values. RESULTS In women with subsequent preeclampsia, sL-selectin and sVCAM-1 concentrations were significantly lower, whereas sE-selectin, sP-selectin and sICAM-1 levels were significantly higher, compared with controls at mid-pregnancy (p<0.05). The odds ratio for low sL-selectin was 25.6 (95% CI, 8.9-73.5; cut-off, 1414 ng/ml). The sensitivity, specificity, and positive and negative predictive values of low sL-selectin for preeclampsia development were 84, 90, 39, and 98%, respectively, whereas its sensitivity, specificity, and positive and negative predictive values for severe preeclampsia development (cut-off, 1210 ng/ml) were 100, 98, 60, and 100%, respectively. CONCLUSIONS Early enhanced activation of endothelial cells, platelets and leukocytes seem to be present in preeclamptic patients, especially in those that develop severe preeclampsia. Low sL-selectin levels at 20 gestation weeks may be an indicator of preeclampsia development.

Abstract
OBJECTIVE To investigate the effect of serum on the interaction between natural killer (NK) cells and endothelial cells in pre-eclampsia. METHODS Seven severely pre-eclamptic patients, five normal pregnant women, and four normal non-pregnant women were included in this study. Freshly isolated NK cells labeled with Chromium-51 were incubated on an endothelial cell monolayer in the presence of patient serum. In regard to the characteristics of adhesive molecules, the endothelial cells were blocked by monoclonal antibodies (mAbs) to intracellular adhesion molecule-1 (ICAM-1), vascular cell adhesion molecule-1 (VCAM-1); the NK cells were blocked by mAbs to leukocyte function-associated antigen (LFA-1) and very late antigen-4 (VLA-4) before co-incubation. After incubation, the adherent cells were solubilized with 1% Triton X. The lysates were collected and counted in a gamma counter. RESULTS The adhesion of NK cells to the endothelium in the normal pregnancy group decreased significantly in comparison to the non-pregnant group (7%vs 72%; P < 0.01). Adhesion in the severe pre-eclamptic group was significantly higher in comparison to the normal pregnant group (44%vs 7%; P < 0.01). The blocking percentages of mAbs on NK adhesion in the severe pre-eclampsia group were 49 +/- 4% to LFA-1, 61 +/- 48%, 67 +/- 39% to VLA-4, ICAM-1, and 68 +/- 7% to VCAM-1. CONCLUSION Sera from normal pregnant women suppress the adhesion between NK cells and endothelial cells, whereas the suppressive effect of sera from pre-eclamptic patients has a diminished affect.

Abstract
OBJECTIVES Maternal physiology at high altitude could be considered to resemble an intermediate state between preeclampsia and normal pregnancy. The objective of the current study was to determine if cell adhesion molecules, known to be increased in preeclampsia, are increased with chronic maternal and placental hypoxia (due to high-altitude residence) in the absence of preeclampsia. METHODS Serum was collected from women residing at 3100 m or 1600 m in the three trimesters of pregnancy and postpartum. Vascular cell adhesion molecule-1 (VCAM-1), E-selectin, and intercellular adhesion molecule-1 (ICAM-1) were measured by enzyme-linked immunosorbent assay (ELISA). RESULTS General linear model (GLM) repeated measures analysis of VCAM-1, E-selectin, and ICAM-1 data showed there were no statistically significant effects of gestation within either the high- or moderate-altitude groups or between the different altitudes. CONCLUSION The increase in cell adhesion molecules reported in preeclampsia is not present in pregnant women at high altitude, suggesting that maternal systemic hypoxia is not responsible for this pathway of endothelial cell activation in preeclampsia.

Abstract
OBJECTIVE The purpose of this study was to evaluate possible relationships between placental markers and endothelial dysfunction in preeclampsia and intrauterine growth restriction. STUDY DESIGN A prospective study was conducted in 76 patients with preeclampsia and 37 patients with intrauterine growth restriction that were classified as early onset (<34 weeks of gestational age) or late onset, and 40 control subjects. Plasma levels of placental growth factor, soluble fms-like tyrosine kinase-1, vascular cell adhesion molecule-1, and uterine artery Doppler indices were measured. RESULTS In early-onset preeclampsia and intrauterine growth restriction, placental growth factor was lower and soluble fms-like tyrosine kinase-1 and vascular cell adhesion molecule-1 higher than in control subjects, although all changes were more pronounced in preeclampsia. In late-onset preeclampsia, those patients with abnormal uterine artery Doppler indices had higher soluble fms-like tyrosine kinase-1 and vascular cell adhesion molecule-1 levels. CONCLUSION Biochemical changes in early-onset preeclampsia and intrauterine growth restriction point to a common placental disorder and a state of endothelial dysfunction, which may require interaction with other factors to explain the maternal disease in preeclampsia. Data in late-onset preeclampsia suggest that a proportion of them may occur with minimal placental involvement.

Abstract
It is hypothesized that preeclampsia is caused by factors from the placenta that induce endothelial cell activation. Trophoblasts are cells that may be shed from the placenta, then deported in the maternal blood, and finally become trapped in the pulmonary capillaries. The ultimate fate of deported trophoblasts is unknown, but to prevent clogging of the pulmonary circulation they must be cleared from the capillary beds. We examined the hypothesis that endothelial cells phagocytose deported trophoblasts and also examined the consequent effects of the trophoblasts on endothelial cells. Fluorescently labeled trophoblast–derived choriocarcinoma cells were induced to become apoptotic or necrotic and exposed to endothelial cell monolayers. Confocal microscopy demonstrated uptake of both apoptotic and necrotic trophoblasts, and this phagocytosis could be inhibited by cytochalasin B. Phagocytosis of necrotic but not apoptotic trophoblasts induced increased endothelial intercellular adhesion molecule 1 (ICAM-1) expression, as well as increased adhesion of monocytes to endothelial cell monolayers. Inhibiting the phosphatidylinositol 3-kinase and p38 mitogen-activated protein kinase pathways blocked both expression of ICAM-1 and phagocytosis, whereas inhibition of the P42/44 mitogen-activated protein kinase pathway blocked only ICAM-1 expression. This work suggests that endothelial cells can phagocytose deported trophoblasts and that the mechanism of trophoblast death (apoptotic or necrotic) could have major effects on the maternal vascular response to shed trophoblasts.

Abstract
OBJECTIVE Soluble vascular cell adhesion molecule-1 (VCAM-1) is known to be elevated in serum of patients with preeclampsia, but there are no data available on the significance of urinary VCAM-1 excretion in preeclampsia. The aim of our study was to uncover possible circadian rhythms of VCAM-1 plasma levels and urinary VCAM-1 excretion in uncomplicated and hypertensive pregnancies and to ascertain their relation to blood pressure. STUDY DESIGN A total of 10 normotensive and 10 preeclamptic pregnant women were included in this study. Venous blood was collected hourly, and urine samples were taken every 2 h over a period of 24 h. VCAM-1 levels were determined by ELISA. We compared these results with the circadian blood pressure rhythm. RESULTS The median VCAM-1 plasma levels were significantly (P < 0.01) increased in preeclamptic patients (851.5 ng/mL) in comparison to normotensive pregnant women (659.3 ng/mL) without any circadian rhythm being apparent; however, the urinary excretion of VCAM-1 showed a typical circadian rhythm, with a higher excretion rate during daytime. CONCLUSION For the first time we have demonstrated that urinary VCAM-1 excretion in pregnancy shows a circadian rhythm without correlation to plasma levels or the circadian blood pressure rhythm. In contrast, VCAM-1 serum levels did not show a diurnal rhythm. We assume that VCAM-1 serum levels do not correlate with systemic blood pressure or urinary excretion.

Abstract
Endothelial dysfunction is thought to be a central pathogenic feature in preeclampsia on the basis of elevated adhesion molecules. The aim of the present study was to compare the levels of soluble vascular cell adhesion molecule-1 (sVCAM-1), intercellular adhesion molecule-1 (sICAM-1) and E-selectin (sE-selectin) in sera of normal and preeclamptic pregnancies. We studied the serum levels of sVCAM-1, sICAM-1 and sE-selectin in normal pregnant women (n=63), mild preeclampsia (n=33) and severe preeclampsia (n=82). Concentrations of soluble adhesion molecules were determined with enzyme-linked immunoassay (ELISA). Serum concentrations of sVCAM-1 were significantly higher in both mild (p=0.004) and severe preeclampsia (p=0.000) than normal pregnancy. There were also significant differences in sVCAM- 1 levels between mild and severe preeclampsia (p=0.002). sICAM-1 levels of severe preeclampsia were statistically different from those of normal pregnancy (p=0.038). Levels of sE-selectin were elevated in both mild (p=0.011) and severe preeclampsia (p=0.000) compared to normal pregnancy, but no statistical difference between the mild and severe preeclampsia (p=0.345). These results suggest that all three soluble adhesion molecules are increased in severe preeclampsia, and sVCAM-1 among them may be useful in predicting the severity of preeclampsia.

Abstract
OBJECTIVE The aim of this study was to analyze if levels of plasma PlGF in the second half of pregnancy have predictive value for the identification of women destined to develop preeclampsia or another complication of pregnancy. MATERIAL AND METHODS A bank of 1.543 randomly collected plasma samples (22-29 weeks of gestation) was established and PlGF concentrations were quantitated in a prospective longitudinal study in all pregnant women who developed a complication of pregnancy in late gestation (177 of 1.543) and the same number of gestational age matched pregnancies with normal outcome. RESULTS Plasma PlGF levels in pregnant women rise steadily throughout pregnancy from the level of nonpregnant women (< 50 pg/mL) to levels exceeding 500 pg/mL after 30 weeks of gestation. Just 7.3% of pregnant women with normal outcome of pregnancy had PlGF levels of less than 200 pg/mL beyond 22 weeks of gestation (3.7% beyond 25 weeks of gestation). The rise in plasma PlGF in the second half of pregnancy was significantly attenuated in pregnancies that were complicated by preeclampsia in late gestation. Of all women who developed preeclampsia, 27.3% (12 of 44) had plasma PlGF levels below 200 pg/mL. The attenuation of the rise in plasma PlGF was not evident in other complications of pregnancy (transient hypertension, fetal retardation, pregnancy diabetes, premature contractions, proteinuria without hypertension, infections during pregnancy). CONCLUSION The rise in plasma PlGF levels observed in normal pregnancies is significantly attenuated in pregnancies complicated by preeclampsia. Yet, due to the low sensitivity and specificity, plasma PlGF levels in the second half of pregnancy have no predictive value for the identification of individual women destined to develop preeclampsia.

Abstract
Hyperhomocyst(e)inemia (HHcy) is a risk factor of endothelial dysfunction and preeclampsia. Soluble vascular cell adhesion molecule-1 (sVCAM-1), a specific marker of endothelial dysfunction, is elevated in preeclampsia. Few have assessed the joint contribution of these biomarkers in predicting preeclampsia. We assessed the extent to which HHcy and elevated sVCAM-1 are independently and jointly associated with preeclampsia. We conducted a case-control analysis of 100 preeclampsia cases and 100 controls to test our study hypothesis. Maternal plasma was collected before labor onset. Total plasma homocysteine (tHcy) was measured using high-performance liquid chromatography with electrochemical detection procedures. Plasma sVCAM-1 was determined using ELISA. Using the distribution of each analyte among controls, elevated tHcy was defined as plasma tHcy >6.6 micromol/l and elevated sVCAM-1 was defined as plasma concentrations >845 ng/ml (i.e., values above the median). Odds ratios (OR) and 95% confidence intervals (CIs) were calculated. Compared with women without elevated tHcy and without elevated sVCAM-1 (the referent group), those with elevated sVCAM-1 alone had a 4.1-fold increased risk of preeclampsia (95% CI 1.2-13.8). The OR for women with elevated tHcy alone was 2.2 (95% CI 0.6-7.9). The OR for women with elevated tHcy and sVCAM-1 was 13.2 (95% CI 4.1-42.2). Elevated tHcy and sVCAM-1 together were strongly associated with an increased risk of preeclampsia. Larger, prospective studies are needed to confirm these findings and to determine the extent to which elevated tHcy and sVCAM-1 together in early pregnancy are predictive of preeclampsia risk.

Abstract
OBJECTIVE Fetal growth restriction is associated with an abnormal umbilical artery Doppler study. A vascular disease is present in the fetal umbilical placental microcirculation. We hypothesized that the local production of factors that are injurious to microvessel endothelium is responsible for this vascular disease and that endothelial cell activation is a feature of this. Because the expression of the cell adhesion molecules is associated with endothelial cell activation, we isolated endothelial cells from the microvessels of the umbilical placenta and examined them for evidence of gene expression of cell adhesion molecules. STUDY DESIGN Endothelial cells from the microcirculation of human placenta were isolated and purified with collagenase digestion and extraction with superparamagnetic beads that were coated with monoclonal antibody against CD31. Microvessel endothelial cells were isolated from the placentae of 13 women with a normal pregnancy and delivery at term and 10 placentas with umbilical placental vascular disease that was defined by abnormal umbilical artery Doppler study. Total RNA was extracted from isolated endothelial cells. The messenger RNA expressions of cell adhesion molecules (intercellular adhesion molecule-1, vascular cell adhesion molecule-1, and platelet endothelial cell adhesion molecule-1) were assessed by semiquantitative reverse transcription-polymerase chain reaction. RESULTS Microvessel endothelial cells from the fetal placentae of pregnancies that were complicated by umbilical placental vascular disease showed an enhanced expression of intercellular adhesion molecule-1 messenger RNA (2.12+/-0.45 vs 0.92+/-0.25) and platelet endothelial cell adhesion molecule-1 messenger RNA (4.29+/-0.87 vs 2.41+/-0.42) in comparison to normal pregnancies. There was no significant difference in expression of vascular cell adhesion molecule-1 messenger RNA (1.55+/-0.37 vs 1.68+/-0.38). CONCLUSION We have shown that vascular disease in the fetal umbilical placental circulation is associated with an increase in the expression of intercellular adhesion molecule-1 and platelet endothelial cell adhesion molecule-1 by microvessel endothelial cells. We postulate that locally released factors cause injury and activation to microvessel endothelial cells. In this regard, the process in the fetus is similar to that of atherothrombotic vascular disease of later life.

Abstract
OBJECTIVE To determine if neutrophil activation is a pathogenetic factor in hypertensive disorders in pregnancy, the neutrophil expression of adhesion molecules was prospectively investigated in pregnant women at risk, prior to the development of hypertensive complications. METHODS Two neutrophil activation parameters, beta2-integrin (CD11b) and l-selectin (CD62L), were assessed at admission between 14 and 24 weeks of gestation in 82 pregnant women at risk of preeclampsia and other hypertensive complications. Results were compared to those in 20 healthy normotensive women. RESULTS Of the 82 women at risk, 23 (28%) developed hypertensive complications: 9 (11%) preeclampsia and 14 (17%) others, such as intrauterine growth restriction (n = 6), fetal or neonatal loss (n = 8), and preterm delivery (< or = 30 weeks of gestation) (n = 8). All pregnancy outcome measures were significantly worse in the patients with complications than in those at risk but without complications or the healthy controls. Expression of beta2-integrin was significantly higher in early stages of pregnancy in the women who eventually developed complications than the women who did not, P =.019, or the healthy controls, P =.049. CONCLUSIONS Surface expression of beta2-integrin is increased in pregnant women at risk for hypertensive complications before the clinical manifestations of the disorder.

Abstract
OBJECTIVE Poor placentation in early pregnancy is thought to lead to an excessive maternal systemic inflammatory response, which causes the maternal syndrome of preeclampsia. The aims of this retrospective study were to confirm old reports of increased blood levels of pregnancy-associated plasma protein A (PAPP-A) in preeclampsia and how its levels correlate with the levels of other placental and endothelial proteins that are reported to be elevated in preeclampsia. METHODS Nineteen women with preeclampsia symptoms were matched with 19 normal pregnant controls for gestational age, maternal age, and parity. PAPP-A, placental pregnancy-specific beta1-glycoprotein (SP1), inhibin A, activin A, and sE-selectin were measured in serum using specific ELISAs. RESULTS Maternal serum levels of PAPP-A, inhibin A, activin A and sE-selectin were increased in women with preeclampsia (mean 157.7 vs. 76.85 mIU/mL, p=0.005; 3.08 vs. 1.51 ng/mL, p=0.002, 32.36 vs. 3.77 ng/mL, p<0.001 and 62.15 vs. 46.37 ng/mL, p=0.02 respectively), compared to controls. Serum levels of SP1 were not altered in preeclampsia. PAPP-A (r=0.636, p<0.01) had a positive correlation with sE-selectin in patients with preeclampsia. Serum inhibin A and activin A had a significant positive correlation with each other in preeclampsia. CONCLUSIONS Raised levels of PAPP-A in preeclampsia confirm earlier reports. Activin A showed the highest increase over the controls and is thus likely to be a better serum marker for this pathology than the other markers that were tested.

Abstract
Although there is substantial evidence that preeclampsia has a genetic background, the complexity of the processes involved and the fact that preeclampsia is a maternal-fetal phenomenon does not make the search for the molecular basis of preeclampsia genes easy. It is possible that the single phenotype 'preeclampsia' in fact should be divided into different sub-groups on genetic or biochemical level. In the present review, the preeclampsia phenotype and its pathophysiologic features are discussed. Family studies and postulated inheritance models are summarized. A systematic overview is given on the numerous candidate gene studies and gene-expression studies performed so far and on the currently available genome-wide scan data. Despite extensive research the molecular genetic basis of preeclampsia remains unclear. Future studies will hopefully enhance our insights in the molecular pathogenesis of preeclampsia.

Abstract
Abstract
Background: The present study was aimed at determining whether routine prenatal measurements of circulating soluble intercellular adhesion molecule (sICAM-1; CD54) and soluble vascular cell adhesion molecule (sVCAM-1; CD106) in midgestation have predictive value for the identification of pregnant women destined to develop preeclampsia or other complications of pregnancy during late gestation.
Methods: Plasma sICAM-1 and sVCAM-1 were analyzed between weeks 22 and 29 of gestation in 1543 pregnant women and related to the outcome of pregnancy in a prospective longitudinal study.
Results: Plasma sICAM-1 and sVCAM-1 in uncomplicated pregnancies were normally distributed and varied over a small range (sICAM-1, SD = 22.5%; sVCAM-1, SD = 25.5%). Of all analyzed uncomplicated pregnancies, 54 (3.95%) were identified with concentrations of sICAM-1 or sVCAM-1 above the mean + 2 SD. In contrast, of 177 pregnancies with complications (prevalence, 11.5%), 97 (55%) had sICAM-1 or sVCAM-1 concentrations above the same cutoffs weeks before the onset of disease. The sensitivities of sICAM-1 and sVCAM-1 measurements were 66% for preeclampsia and hemolysis, elevated liver enzymes, and low platelets (HELLP syndrome), 42% for gestational hypertension, 50% for fetal retardation, 46% for preterm labor, 50% for gestational diabetes mellitus, 67% for gestational proteinuria, and 70% for infections during pregnancy. Taken together, routine prenatal sICAM-1 and sVCAM-1 measurements had an overall predictive value of 64%.
Conclusions: Midgestation measurements of circulating sICAM-1 and sVCAM-1 have a high predictive value (area under the curve of combined sICAM-1 and sVCAM-1 measurements determined by ROC analysis, 0.85) and may identify up to 55% of pregnant women who will later develop a severe pregnancy-related complication.

Abstract
PROBLEM To clarify the possible influence of human leukocyte antigen (HLA) mother-child genotypes and human cytomegalo virus (HCMV) presence on the development of preeclampsia. METHODS OF STUDY One hundred and four DNA samples from mothers with preeclampsia, mothers with a normal history of pregnancies and their neonates were tested by polymerase chain reaction-sequence specific oligonucleotide probes (PCR-SSOP) for HLA-A, -G, -DRB1, -DQA1, -DQB1 alleles. The HCMV sequences were analyzed using a PCR-SSOP method and the four primers described by Chou (Chou S: J Clin Microb 1992; 30:2307-2310). RESULTS Compared with their respective controls, a significant increase of DRB1*07 among neonates (P(c) = 0.05) and of DRB1*07 and/or DRB1*06 among pre-eclamptic mothers (P(c) = 0.003, RR = 8,5) was found. When HCMV sequences were detected in pre-eclamptic mothers carrying those phenotypes the RR increased up to 40. Furthermore, the fetal inheritance of a maternal HLA-G*0104 increased the risk for the appearance of the disease (RR = 30; P = 0.025). CONCLUSION The results suggest that the presence of alleles HLA-G*0104, DRB1*07/06, HCMV sequences and the fetal inheritance of maternal G*0104, should be considered as conditioning factors for the development of preeclampsia.
