Abstract
OBJECTIVE Preeclampsia (PE) is a disorder that occurs during the pregnancy and could affect the maternal and perinatal mortality as well as morbidity. The aim of our study is to investigate the associations between the hypertension susceptibility genes ITGA9, MOV10 and CACNB2 with PE in Chinese Han population. METHODS A case-control study including 178 PE patients and 202 healthy controls was conducted to assess the associations between three loci (ITGA9 rs155524, MOV10 rs2932538 and CACNB2 rs4373814) and PE. The TaqMan probe assay was applied for genotyping in our study. Quantitative real-time PCR was performed to detect the mRNA expression levels of ITGA9, MOV10 and CACNB2. ELISA was carried out to detect the concentration of serum sFlt-1 or PLGF. RESULTS Our study detected no significant differences in allelic frequencies of three SNPs between PE patients and healthy controls. In the genetic model, the results showed that the patients with ITGA9 rs155524 GA or AA genotypes had a higher risk of PE development compared to those with GG genotype in codominant model. And PE patients had a higher frequency of GA + AA genotypes based on the dominant model. Subgroup analysis showed ITGA9 rs155524 was associated with early-onset PE but not with late-onset PE. No association was observed between MOV10 and CACNB2 with PE in any genetic model and subgroup analysis. Quantitative real-time PCR results showed that ITGA9 mRNA expression level was apparently increased in the placental tissues of PE patients. In addition, ITGA9 expression levels of GA + AA subjects were apparently higher than that in the genotype GG of placental tissues. sFlt-1/PLGF ratio was higher in GA + AA subjects than that in GG subjects. Regression analysis revealed that ratio of sFlt-1/PLGF was positively correlated with ITGA9 mRNA expression level. CONCLUSION This study has identified ITGA9 is a promising candidate susceptibility gene for early-onset PE. Our findings demonstrated that the high expression of ITGA9 might be associated with an increased risk of PE.

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
Objective: Endocan, a dermatan sulphate proteoglycan produced by endothelial cells, is considered a biomarker for endothelial cell activation/dysfunction. Preeclampsia is characterized by systemic vascular inflammation, and endothelial cell activation/dysfunction. Therefore, the objectives of this study were to determine whether: (1) plasma endocan concentrations in preeclampsia differ from those in uncomplicated pregnancies; (2) changes in plasma endocan concentration relate to the severity of preeclampsia, and whether these changes are specific or observed in other obstetrical syndromes such as small-for-gestational age (SGA), fetal death (FD), preterm labor (PTL) or preterm prelabor rupture of membranes (PROM); (3) a correlation exists between plasma concentration of endocan and angiogenic (placental growth factor or PlGF)/anti-angiogenic factors (soluble vascular endothelial growth factor receptor or sVEGFR-1, and soluble endoglin or sEng) among pregnancies complicated by preeclampsia; and (4) plasma endocan concentrations in patients with preeclampsia and acute pyelonephritis (both conditions in which there is endothelial cell activation) differ. Method: This cross-sectional study included the following groups: (1) uncomplicated pregnancy (n = 130); (2) preeclampsia (n = 102); (3) pregnant women without preeclampsia who delivered an SGA neonate (n = 51); (4) FD (n = 49); (5) acute pyelonephritis (AP; n = 35); (6) spontaneous PTL (n = 75); and (7) preterm PROM (n = 64). Plasma endocan concentrations were determined in all groups, and PIGF, sEng and VEGFR-1 plasma concentrations were measured by ELISA in the preeclampsia group. Results: (1) Women with preeclampsia had a significantly higher median plasma endocan concentration than those with uncomplicated pregnancies (p = 0.004); (2) among women with preeclampsia, the median plasma endocan concentration did not differ significantly according to disease severity (p = 0.1), abnormal uterine artery Doppler velocimetry (p = 0.7) or whether diagnosis was made before or after 34 weeks gestational age (p = 0.3); (3) plasma endocan concentration in women with preeclampsia correlated positively with plasma anti-angiogenic factor concentrations [sVEGFR-1: Spearman rho 0.34, p = 0.001 and sEng: Spearman rho 0.30, p = 0.003]; (4) pregnancies complicated by acute pyelonephritis with bacteremia had a lower median plasma endocan concentration than pregnancies complicated by acute pyelonephritis without bacteremia (p = 0.004), as well as uncomplicated pregnancies (p = 0.001); and (5) there was no significant difference in the median plasma endocan concentration between uncomplicated pregnancies and those complicated by FD, delivery of an SGA neonate, PTL or preterm PROM (other members of the “great obstetrical syndromes”; each p > 0.05). Conclusion: Median maternal plasma endocan concentrations were higher preeclampsia and lower in acute pyelonephritis with bacteremia than in uncomplicated pregnancy. No significant difference was observed in the median plasma endocan concentration between other great obstetrical syndromes and uncomplicated pregnancies. The difference in the direction of change of endocan in preeclampsia and acute pyelonephritis with bacteremia may be consistent with the view that both disease entities differ in pathogenic mechanisms, despite their associations with systemic vascular inflammation and endothelial cell activation/dysfunction.

Abstract
Pre-eclampsia is a serious hypertensive condition of pregnancy associated with high maternal and fetal morbidity and mortality. Se intake or status has been linked to the occurrence of pre-eclampsia by our own work and that of others. We hypothesised that a small increase in the Se intake of UK pregnant women of inadequate Se status would protect against the risk of pre-eclampsia, as assessed by biomarkers of pre-eclampsia. In a double-blind, placebo-controlled, pilot trial, we randomised 230 primiparous pregnant women to Se (60 μg/d, as Se-enriched yeast) or placebo treatment from 12 to 14 weeks of gestation until delivery. Whole-blood Se concentration was measured at baseline and 35 weeks, and plasma selenoprotein P (SEPP1) concentration at 35 weeks. The primary outcome measure of the present study was serum soluble vascular endothelial growth factor receptor-1 (sFlt-1), an anti-angiogenic factor linked with the risk of pre-eclampsia. Other serum/plasma components related to the risk of pre-eclampsia were also measured. Between 12 and 35 weeks, whole-blood Se concentration increased significantly in the Se-treated group but decreased significantly in the placebo group. At 35 weeks, significantly higher concentrations of whole-blood Se and plasma SEPP1 were observed in the Se-treated group than in the placebo group. In line with our hypothesis, the concentration of sFlt-1 was significantly lower at 35 weeks in the Se-treated group than in the placebo group in participants in the lowest quartile of Se status at baseline (P= 0·039). None of the secondary outcome measures was significantly affected by treatment. The present finding that Se supplementation has the potential to reduce the risk of pre-eclampsia in pregnant women of low Se status needs to be validated in an adequately powered trial.

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
AIM This study aims to test the hypothesis that vascular dysfunction is present early in pregnancy in women with type 1 diabetes who subsequently develop preeclampsia. METHODS Eighty-three women with type 1 diabetes of more than 10 years duration were followed up prospectively during pregnancy. External ultrasound was used to measure the dilatory response of the brachial artery to postischemic increased blood flow (endothelium-dependent, flow-associated dilatation) and to nitroglycerin (NTG) [endothelium-independent, NTG-induced dilatation (NID)] at Gestational Weeks 11 and 29. Plasma concentrations of the vascular markers vascular cell adhesion molecule-1 (VCAM-1), intercellular adhesion molecule-1 (ICAM-1), E-selectin, and von Willebrand factor antigen were also measured together with 24-h urinary albumin excretion (UAE), blood pressure (BP), and HbA(1C). RESULTS Fourteen (17%) of the 83 women developed preeclampsia. NID was significantly impaired at Week 29 in women prone to preeclampsia (108.8+/-7.0% vs. 116.8+/-8.9%, mean+/-S.D., P<.05), and the plasma concentrations of VCAM-1 and ICAM-1 were significantly elevated at Gestational Week 11 (612+/-82 vs. 516+/-109 microg/l, P<.005 and 293+/-67 vs. 255+/-57 microg/l, P<.05, respectively). Women who later developed preeclampsia were also characterized by higher UAE, higher BP, and higher HbA(1C) than women who did not [Gestational Week 11: 194 (3-1104) vs. 7 (0-412) mg/24 h, median (range), P=.0003; 122+/-12/75+/-6 vs. 111+/-11/69+/-9 mmHg, mean+/-S.D., P<.01; and 8.2% (5.9-10.5%) vs. 7.2% (5.3-10.9%), P=.008, respectively]. CONCLUSION This prospective study indicates that signs of maternal vascular dysfunction precede development of preeclampsia in women with type 1 diabetes.

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
OBJECTIVE We recently developed a novel sandwich chemiluminescence assay to determine serum concentrations of periostin. Periostin has high amino acid homology with transforming growth factor-beta-induced protein beta igh3, a molecule induced by transforming growth factor-beta(1), which promotes the adhesion and spreading of fibroblasts. It is also homologous with the insect cell adhesion molecule fasciclin I. We determined serum periostin concentrations in women with preeclampsia and in normotensive pregnant women. STUDY DESIGN The study groups included 30 women with preeclampsia and 30 normotensive pregnant women at Magee-Womens Hospital. Blood samples collected from these women were assayed for periostin by use of newly developed monoclonal and polyclonal antibodies. We studied periostin messenger ribonucleic acid (mRNA) expression in human tissues by using reverse transcriptase-polymerase chain reaction and in situ hybridization. RESULTS Serum periostin concentrations were elevated in patients with preeclampsia (mean +/- SD, 311.8 +/- 56.3 ng/mL) compared with normotensive pregnant women (218.8 +/- 37.3 ng/mL). No correlation was found between serum concentrations of periostin and concentrations of TGF-beta(1), vascular cell adhesion molecule-1 (VCAM-1), E-selectin, and interleukin-6. Reverse transcriptase-polymerase chain reaction analysis demonstrated human periostin expression in lung, kidney, and placenta but not in the heart, liver, brain, or skeletal muscle. For periostin complementary deoxyribonucleic acid cloned from placenta, there was a splicing deletion within the C-terminal domain. In situ hybridization data showed that the periostin gene was expressed in the stroma cells of placenta. CONCLUSION Our study suggests that human periostin may play a role in the pathogenesis of preeclampsia. Although its function remains unclear, the expression of periostin as an adhesion molecule could suggest novel mechanisms in preeclampsia.

Abstract
UNLABELLED The adaptation of vascular tone in early pregnancy precedes and probably triggers blood volume and cardiac output increase. Because the endothelium is known to regulate vascular smooth muscle action, the role of nitric oxide (NO) in the setting up of adequate uteroplacental and renal blood flow during normal pregnancy was investigated. The persistence of abnormally high uteroplacental resistance is a strong predisposing factor for intrauterine growth retardation and preeclampsia and can be screened by second trimester Doppler assessment of the uterine arteries. Current hypotheses suggested by experimental and clinical data concerning preeclampsia confirm the crucial role played by the endothelium and vascular tone adaptation. The analysis of these data leads to consider apart early-onset preeclampsia affecting pregnancies with growth retarded fetuses and associated with high vascular resistance. Lastly, NO donors seem to significantly decrease the impedance in the uteroplacental circulation and to improve fetoplacental hemodynamics assessed by Doppler measurements, and their therapeutic use in some forms of preeclampsia might be promising. TARGET AUDIENCE Obstetricians & Gynecologists, Family Physicians LEARNING OBJECTIVES After completion of this article, the reader will be able to summarize the events that regulate vascular tone in pregnancy, specifically the role of nitric oxide and other vasoactive prostaglandins in the regulation of vascular tone and to describe the various hypotheses concerning the mechanism and the mediators responsible for initiating endothelial damage in the various disorders of vascular tone in pregnancy.
