Abstract
Preeclampsia is a complex disease of pregnancy whose physiopathology remains unclear. We developed machine-learning models for early prediction of preeclampsia (first 16 weeks of pregnancy) and over gestation by analyzing six omics datasets from a longitudinal cohort of pregnant women. For early pregnancy, a prediction model using nine urine metabolites had the highest accuracy and was validated on an independent cohort (area under the receiver-operating characteristic curve [AUC] = 0.88, 95% confidence interval [CI] [0.76, 0.99] cross-validated; AUC = 0.83, 95% CI [0.62,1] validated). Univariate analysis demonstrated statistical significance of identified metabolites. An integrated multiomics model further improved accuracy (AUC = 0.94). Several biological pathways were identified including tryptophan, caffeine, and arachidonic acid metabolisms. Integration with immune cytometry data suggested novel associations between immune and proteomic dynamics. While further validation in a larger population is necessary, these encouraging results can serve as a basis for a simple, early diagnostic test for preeclampsia.

Abstract
Triggering receptor expressed on myeloid cells (TREM) like transcript-1 (TLT-1) is a membrane protein receptor found in α-granules of megakaryocytes and platelets. Upon platelet activation TLT-1 is rapidly relocated to the surface of platelets. In plasma, a soluble form of TLT-1 (sTLT-1) is present. Plasma levels of sTLT-1 are significantly elevated in thrombotic diseases. In the present study, we investigated to whether TLT-1 reflects platelet activation in pregnant women with preeclampsia. We studied 30 preeclamptic patients who were matched with 30 normotensive pregnant women and 30 non-pregnant controls. Basal TLT-1, P-selectin, and CD63 expressions on platelets were analyzed with the use of flow-cytometry (FCM). Platelet reactivity was induced by thrombin receptor activation peptide and determined by FCM. Plasma concentrations of sTLT-1 and soluble P-selectin (sP-selectin) were measured by an enzyme-linked immunosorbent assay. Results show that basal platelet expression of TLT-1, P-selectin and CD63 were increased in women with preeclampsia (PE) compared with normotensive pregnant women (NP). Platelets from PE women and NP women were more responsive compared to from nonpregnant women controls (NC), and which was demonstrated by increased expression of TLT-1, P-selectin, and CD63 upon stimulation in vitro. Plasma concentration of sTLT-1 was greater in PE women compared to NP women and NC women. Plasma sP-selectin level was higher in pregnant women than in nonpregnant women, but there were no significant differences between PE and NP women. In summary, our results revealed that platelet activation is prominent in preeclampsia, TLT-1 reflects platelet activation and may be a useful indicator for preeclampsia.

Abstract
Vascular dysfunction is a hallmark of cardiovascular disease (CVD). Offspring from preeclamptic pregnancies are at risk of CVD later in life. Whether fetal vasculature from preeclamptic pregnancies displays signs of vascular dysfunction (i.e., oxidative/nitrosative stress, endothelial activation) associated with increased expression of lectin-like oxidized LDL receptor-1 (LOX-1) and angiotensin-II type-1 receptor (AT1) is unknown. We demonstrated increased superoxide, nitrotyrosine and ICAM-1 levels in umbilical vein tissues of preeclamptic vs. normal pregnancies; without changes in LOX-1 and AT1 levels. Our findings suggest that the fetal vasculature may be impacted in preeclampsia, which could contribute to an increased risk of offspring CVD.

Abstract
Selectins [endothelial (E), platelet (P), and leucocytes (L)] are a class of cell adhesion molecules, stimulated in response to inflammation. Pre-eclampsia is characterized by inflammation, and angiotensin II is pro-inflammatory. We hypothesized that circulating maternal and fetal concentrations and placental expression of selectins would be increased in women with pre-eclampsia and would be associated with the angiotensin receptors (AT1R and AT2R). Maternal and fetal blood and placental tissue was collected at delivery from White European normotensive controls (n = 17) and women with pre-eclampsia (n = 17). Soluble (s) E-, P- and L-selectin protein concentrations were measured by ELISA and placental protein expression was examined by immunohistochemistry. Maternal sE-selectin concentrations were increased in pre-eclampsia (P < 0.001); conversely fetal sE- and sP-selectin levels were lower in pre-eclampsia (P < 0.05 for both). Staining was mainly localized to the syncytiotrophoblast for all selectins. E-selectin expression was increased, while P-selectin was decreased in placental from pre-eclampsia (P < 0.05 for both); no differences were observed for L-selectin expression. Both E- and L-selectin were positively correlated (P < 0.008; P < 0.02) with AT2R placental expression, whilst P-selectin was negatively associated with AT1R (P < 0.005), all only in the pre-eclampsia group. This novel study reports maternal, fetal and placental expression of selectins in pre-eclampsia. The increased E-selectins reflect the endothelial dysfunction, characteristic of pre-eclampsia. In contrast, the reduced P-selectins and the positive association of placental AT2Rs with both E-and L-selectin in pre-eclampsia could be a protective mechanism to limit the endothelial dysfunction.

Abstract
Preeclampsia (PE) is a disorder which affects 1-10% of pregnant women worldwide. It is characterised by hypertension and proteinuria in the later stages of gestation and can lead to maternal and perinatal morbidity and mortality. Other than the delivery of the foetus and the removal of the placenta, to date there are no therapeutic approaches to treat or prevent PE. It is thus only possible to reduce PE-related mortality through early detection, careful monitoring, and treatment of the symptoms. For these reasons the search for noninvasive, blood-borne, or urinary biochemical markers that could be used for the screening, presymptomatic diagnosis, and prediction of the development of PE is of great urgency. So far, a number of biomarkers have been proposed for predicting PE, based on pathophysiological observations, but these have mostly proven to be unreliable and inconsistent between different studies. The clinical presentation of PE and data gathered for the biochemical markers placental growth factor (PlGF), soluble Feline McDonough Sarcoma- (fms-) like tyrosine kinase-1 (sFlt-1), asymmetric dimethylarginine (ADMA), and methyl-lysine is being reviewed with the aim of providing both a clinical and biochemical understanding of how these biomarkers might assist in the diagnosis of PE or indicate its severity.

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
INTRODUCTION Preeclampsia (PE) is a major complication of pregnancy that could lead to maternal and fetal morbidity and mortality. The pathophysiological mechanisms of PE are not completely understood, but recent research has begun to unravel some of the potential mechanisms. AREAS COVERED Genetic polymorphisms and altered maternal immune response may cause impaired remodeling of the spiral arteries; a potential early defect in PE. Inadequate invasion of cytotrophoblasts into the decidua leads to reduced uteroplacental perfusion pressure (RUPP) and placental ischemia/hypoxia. Placental ischemia causes the release of biologically active factors such as anti-angiogenic factors, inflammatory cytokines, reactive oxygen species, hypoxia-inducible factors, and angiotensin II receptor autoantibodies. These vasoactive factors could cause systemic vascular endotheliosis and consequent increase in vascular resistance and blood pressure, glomerular endotheliosis causing proteinuria, cerebrovascular endotheliosis causing cerebral edema, seizures and visual disturbances, and hepatic endotheliosis, which may contribute to the manifestations of HELLP syndrome. PE-associated vascular endotheliosis causes a decrease in vasodilator mediators such as nitric oxide, prostacyclin and endothelium-derived hyperpolarizing factor, an increase in vasoconstrictors such as endothelin-1, angiotensin II and thromboxane A2, and enhanced mechanisms of vascular smooth muscle contraction such as intracellular Ca(2+), protein kinase C and Rho-kinase. Changes in matrix metalloproteinase activity and extracellular matrix cause vascular remodeling and further vasoconstriction. EXPERT OPINION Some of the genetic, immune and vasoactive factors involved in vascular endotheliosis could be used as biomarkers for early detection, and as potential targets for prevention and treatment of PE.

Abstract
BACKGROUND Early-onset preeclampsia (EOPET), resulting in intrauterine growth restriction, has serious impact on maternal, perinatal, and neonatal livability worldwide. The current study conducted bioinformatics analyses to screen key genes and microRNAs (miRNAs) involved in EOPET and thus to explore the molecular mechanisms of EOPET. METHODS The microarray data set GSE44711 containing 8 EOPET placentas and 8 gestational age-matched controls was obtained from the Gene Expression Omnibus database. Differentially expressed genes (DEGs) were screened and subjected to gene ontology functional enrichment analysis. Then, Human Protein Reference Database was used to construct protein-protein interaction (PPI) network of DEGs. Besides, we predicted EOPET-associated miRNAs and built the miRNA regulatory network. RESULTS A total of 150 DEGs including 26 upregulated and 124 downregulated genes were obtained. Corticotropin releasing hormone (CRH) and vitronectin (VTN) was the most significantly upregulated and downregulated genes, respectively. The DEGs were mainly related to the biological process (BP) of pregnancy, hormone-involved process, and formation of extracellular region. Analysis of PPI network revealed that fibronectin 1(FN1), FBJ murine osteosarcoma viral oncogene homolog (FOS), CD247 molecule (CD247), VTN, and interleukin 2 receptor, beta (IL2RB) were the top 5 DEGs with highest node degree. Furthermore, many EOPET-associated miRNAs were identified and miR-142-3p was the most significant one. Additionally, multiple miRNAs, such as miR-200b/c and miR-27a/b, were predicted to regulate the expression of several key DEGs. CONCLUSION The current study identified several regulators in EOPET, which may contribute to interpret the molecular mechanism of EOPET and develop novel biomarkers and therapeutic targets for EOPET.

Abstract
A cross-sectional study was conducted in a university hospital, enrolling 40 patients with pre-eclampsia (case group) and 40 healthy normotensive pregnant women (control group). Plasma activity of antioxidants and some adhesion molecules involved in oxidative stress were measured and compared between the two groups, according to the patients' age. In patients over the age of 30 years, serum levels of L-selectin and E-selectin were lower in pre-eclamptic patients (p < 0.05); antioxidants, catalase and superoxide dismutase did not significantly differ between the two groups, while glutathione peroxidase was significantly higher in the normotensive group (p < 0.05). In patients under the age of 30 years, E-selectin was significantly higher in the pre-eclampsia group (p < 0.05), while P-selectin, catalase and superoxide dismutase were not significantly different between the two groups (p > 0.05). Total antioxidative activity was similar between pre-eclamptic and normotensive patients (p > 0.05). This study revealed no relationship between total antioxidant activity and pre-eclampsia.

Abstract
Preeclampsia remains a significant cause of maternal morbidity and mortality worldwide. Prediction, diagnosis and management continue to be challenging but advances in the understanding of the pathophysiological processes underlying the disease has enabled identification of multiple biomarkers, some of which aid prediction of those at risk. Even in isolation, some of these biomarkers have demonstrated sufficient test performance for incorporation into clinical practice. A combination of the most promising biomarkers and clinical factors may improve risk prediction, and aid diagnosis and subsequent management through development of integrated clinical risk models. This article aims to review the literature relating to biomarkers in preeclampsia and summarize the possible clinical applications of these findings.

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
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
OBJECTIVE To determine the relationship between maternal ABO blood group and risk of adverse pregnancy outcomes. STUDY DESIGN Data on ABO phenotypes and pregnancy outcomes were collected from medical records of 5320 singleton pregnant women who had ABO blood testing and follow-up care until delivery in our institution. Adverse pregnancy outcomes that were studied in relation to maternal blood group included preeclampsia, gestational diabetes mellitus (GDM), preterm delivery, low birth weight (LBW) and small for gestational age (SGA) infants. RESULT Out of 5320 women, 350 (6.6%), 333 (6.3%) and 543 (10.2%) women were diagnosed with preeclampsia, GDM and preterm delivery, respectively. LBW and SGA were, respectively, observed in 394 (7.4%) and 178 (3.3%) infants. By uni- and multivariable analyses, women with A or AB blood types, but not B, were found at increased risk of preeclampsia compared with O type individuals; adjusted relative risks were 1.7 (95% confidence interval (CI), 1.3 to 2.3; P=0.001) for A phenotype and 1.7 (95% CI, 1.1 to 2.6; P=0.01) for AB phenotype. There were no significant relationships between blood types and GDM, preterm delivery, LBW or SGA. CONCLUSION Maternal ABO blood group was associated with the risk of preeclampsia, but not with GDM, preterm delivery, LBW or SGA.

Abstract
Background. The posterior reversible encephalopathy syndrome (PRES) is a syndrome characterized by hypertension, headache, seizures, and visual disturbances. Causes of PRES include preeclampsia/eclampsia, hypertension, and recently bevacizumab, a monoclonal antibody vascular endothelial growth factor (VEGF) inhibitor. There is no information to date about PRES recurrence in patients taking bevacizumab or descriptions of deep vein thrombosis (DVT) in the setting of PRES. We reviewed data on a patient receiving bevacizumab who presented with a DVT and PRES and later developed recurrent PRES. Case. A 72-year-old man with metastatic pulmonary adenocarcinoma received maintenance bevacizumab following six cycles of carboplatin and paclitaxel. Following his eighth dose of bevacizumab, he developed a DVT as well as PRES. He made a rapid recovery and was discharged from the hospital but went on to develop PRES recurrence nine days following his original episode. Conclusion. Several mechanisms exist whereby exposure to bevacizumab could be related to the development of both DVT and PRES by inducing global endothelial dysfunction. Recurrent PRES may result from bevacizumab's prolonged half-life (11-50 days) and suboptimal blood pressure control. In the setting of bevacizumab, PRES surveillance may play a similar role in preeclampsia screening as both diseases share similar antiangiogenic signaling pathways.

Abstract
OBJECTIVE Accurate identification of preeclampsia (PE) at triage is essential to reduce maternal and fetal morbidity and mortality. The use of maternal blood based biomarkers may facilitate the clinician's ability to assess high risk pregnancies at triage. METHODS A prospective cross-sectional study was performed to investigate the value of soluble fms-like tyrosine kinase-1 (sFlt-1), soluble endoglin (sEng), placental growth factor (PlGF), sP-selectin, cell-free fetal DNA and total cell-free DNA in patients with late-onset PE versus gestational age-matched controls. RESULTS The diagnosis of late-onset PE (n = 21) at triage was significantly improved by altered levels of sFlt-1, sEng, PlGF and cffDNA as compared with controls (n = 42). Areas under the receiver operating characteristic curves [AUC, Standard error (SE)] for predicting PE were for marker measurements prior to the first stage of labor as follows: sFlt-1 0.97 (SE 0.02), sEng 0.91 (SE 0.04), PlGF 0.95 (SE 0.04), cell-free fetal DNA (DYS 14) 0.84 (SE 0.06), total cell-free DNA (glyceraldehyde 3-phosphate dehydrogenase) 0.61 (SE 0.07), sP-selectin 0.51 (SE 0.07). The discrimination could be slightly improved by using the slt1-PlGF ratio: 0.98 (SE 0.02). CONCLUSION The sFlt-1 is a useful tool for the detection of late-onset PE at triage. This can be slightly improved using a sFlt-1/PIGF ratio. The addition of other biomarkers did not improve screening performance for late-onset PE.

Abstract
AIM(S) To explore the relationship between biomarkers of systemic inflammation in plasma and gingival crevicular fluid in early pregnancy and the subsequent development of pre-eclampsia in patients with periodontitis. MATERIALS AND METHODS A case-control study was performed. From a cohort composed of 126 pregnant women, 43 normotensive healthy pregnant women were randomly selected, and 11 cases of preeclampsia were identified. Plasmatic and gingival crevicular fluid (GCF) samples were collected in early pregnancy (11-14 wk gestation). The levels of interleukin-6 (IL-6) and tumour necrosis factor-α (TNF-α) were measured in the plasma and GCF samples, whereas the level of C-reactive protein (CRP) was measured in plasma samples. Biomarkers were determined by ELISA assays. The data were analysed using descriptive statistics, and the association between variables was estimated through logistic regression models. RESULTS There was observed an association between pre-eclampsia and plasmatic levels of CRP (OR: 1.07; p = 0.003). Additionally, pre-eclampsia also was associated with IL-6 levels in GCF samples in early pregnancy (OR: 1.05; p = 0.039). A multiple logistic regression model suggests that increased levels of IL-6 in GCF (OR = 1.06; p = 0.02; CI 95% 1.007-1.117) in early pregnancy increase the risk of developing pre-eclampsia. CONCLUSION(S) Pregnant women with periodontitis who later development pre-eclampsia, shows increased levels of IL-6 in GCF and CRP in plasma during early pregnancy. Periodontal disease could contribute to systemic inflammation in early pregnancy via a local increase of IL-6 and the systemic elevation of CRP. Therefore, both inflammatory markers could be involved in the relationship between periodontal disease and pre-eclampsia.

Abstract
OBJECTIVE Circulating biomarkers of endothelial dysfunction and inflammation are elevated in late pregnancy in women with preeclampsia. We examined plasma levels of inflammatory cytokines and adhesion molecules in early pregnancy, to assess their ability to predict preeclampsia. METHODS In a prospective longitudinal study, 2600 women with singleton pregnancies and no history of hypertension were recruited at their antenatal hospital (booking) visit at gestational week 12-16. Of these, 49 (1.9%) developed preeclampsia, whereas 74 women matched for age and BMI with uncomplicated pregnancies were selected as controls. A subset of women with risk factors for preeclampsia were sampled again at gestational weeks 16 and 28 (11 cases, 39 controls) and postnatally (six cases, 36 controls). RESULTS From multiplex analysis, soluble E-selectin concentrations were higher at 12-16 weeks in women who subsequently developed preeclampsia (15.1 ± 4.9 versus 12.9 ± 4.5 ng/ml, P = 0.02). At gestational week 28, E-selectin concentrations were again higher in women who went on to develop preeclampsia compared with controls (14.4 ± 5.6 versus 10.7 ± 3.5 ng/ml, P = 0.010), whereas levels were not different between the two groups in postpartum samples. CONCLUSION Changes in soluble E-selectin concentration in early pregnancy may reflect underlying pathophysiological processes, potentially providing mechanistic insights into preeclampsia.

Abstract
OBJECTIVE Preeclampsia is a prevalent and potentially devastating complication of pregnancy. Intercellular adhesion molecule-1 (ICAM-1) was reported to be involved in the pathogenesis of the disease. Therefore we hypothesized anti-ICAM-1 monoclonal antibody (mAb) could be a therapeutic choice for preeclampsia. The objective of this study was to evaluate its therapeutic effects using a rat model of preeclampsia. METHODS Timed pregnant Wistar rats were intravenously injected endotoxin and then randomized to receive either anti-ICAM-1 mAb or saline. The effects of antibody on blood pressure, urinary protein, levels of alanine aminotransferase (ALT), blood urea nitrogen (BUN), creatinine, uric acid, weight of placenta were measured. Pregnancy outcomes were evaluated. RESULTS Anti-ICAM-1 mAb significantly decreased the levels of blood pressure, urinary protein, maternal BUN, creatnine and uric acid comparing with untreated preeclamptic rats. And the antibody therapy significantly improved pregnancy outcomes. After five days of mAb treatment, most of the parameters in mAb-treated group approached normal levels. CONCLUSIONS Our data prove anti-ICAM-1 mAb therapy as a promising choice for preeclampsia.

Abstract
The placenta plays a central role in governing local circulatory system that mediates maternal condition and fetal growth. In early gestational phases, the placenta exerts properties of invasion and neovascularization for successful placentation. Extravillous invasive trophoblasts replace uterine endometrial vasculature and establish local blood pathway to obtain oxygen and nutrients from the mother. In later phases, the placenta promotes villous angiogenesis and vascular maturation that are finely controlled by angiogenic and antiangiogenic molecules. Among various molecules involved in placental neovascularization, vascular endothelial growth factor receptors (VEGFRs) and angiotensin II receptor type 1 (AT1) mediate important signaling pathways for maternal circulatory system and fetal growth. VEGFR1 and VEGFR2 are functional receptors for placental growth factor (PlGF) and VEGF, respectively, and PlGF-VEGFR1 and VEGF-VEGFR2 interactions are disturbed in many preeclamptic patients by excess amount of soluble form of VEGFR1 (also named sFlt1), a natural PlGF/VEGF antagonist. Recent studies have disclosed that excessive sFlt1 production in the placenta and aberrant AT1 signaling in the mother are closely associated with the pathology of preeclampsia and intrauterine growth restriction (IUGR). In this paper, neovascularization of the placenta and pathological events associated with disrupted balance between angiogenic and antiangiogenic signaling in preeclampsia are discussed.

Abstract
Normal pregnancy is associated with significant hemodynamic changes and vasodilation of the uterine and systemic circulation in order to meet the metabolic demands of the mother and developing fetus. Preeclampsia (PE) is one of the foremost complications of pregnancy and a major cause of maternal and fetal mortality. The pathophysiological mechanisms of PE have been elusive, but some parts of the puzzle have begun to unravel. Genetic factors such as leptin gene polymorphism, environmental and dietary factors such as Ca(2+) and vitamin D deficiency, and co-morbidities such as obesity and diabetes may increase the susceptibility of pregnant women to develop PE. An altered maternal immune response may also play a role in the development of PE. Although the pathophysiology of PE is unclear, most studies have implicated inadequate invasion of cytotrophoblasts into the uterine artery, leading to reduced uteroplacental perfusion pressure (RUPP) and placental ischemia/hypoxia. Placental ischemia induces the release of biologically active factors such as growth factor inhibitors, anti-angiogenic factors, inflammatory cytokines, reactive oxygen species, hypoxia-inducible factors, and antibodies to vascular angiotensin II (AngII) receptor. These bioactive factors could cause vascular endotheliosis and consequent increase in vascular resistance and blood pressure, as well as glomerular endotheliosis with consequent proteinuria. The PE-associated vascular endotheliosis could be manifested as decreased vasodilator mediators such as nitric oxide, prostacyclin and hyperpolarizing factor and increased vasoconstrictor mediators such as endothelin-1, AngII and thromboxane A₂. PE could also involve enhanced mechanisms of vascular smooth muscle contraction including intracellular Ca(2+), and Ca(2+) sensitization pathways such as protein kinase C and Rho-kinase. PE-associated changes in the extracellular matrix composition and matrix metalloproteinases activity also promote vascular remodeling and further vasoconstriction in the uterine and systemic circulation. Some of these biologically active factors and vascular mediators have been proposed as biomarkers for early prediction or diagnosis of PE, and as potential targets for prevention or treatment of the disease.

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
OBJECTIVE To examine the performance of screening for pre-eclampsia (PE) and gestational hypertension (GH) by a combination of maternal factors and various biophysical and biochemical markers at 11-13 weeks' gestation. METHODS This was a case-control study of 26 cases of early PE, 90 of late PE, 85 of GH and 201 unaffected controls. Maternal history was recorded, the uterine artery with the lowest pulsatility index (L-PI) and mean arterial pressure (MAP) were measured and stored plasma and serum were analyzed for placental growth factor (PlGF), inhibin-A, activin-A, tumor necrosis factor receptor-1, matrix metalloproteinase-9, pentraxin-3 and P-selectin. RESULTS Multivariate logistic regression analysis demonstrated that significant prediction for early PE was provided by maternal factors, MAP, uterine artery L-PI and serum PlGF. Significant prediction of late PE was provided by maternal factors, MAP, uterine artery L-PI, PlGF, activin-A and P-selectin. For GH significant prediction was provided by maternal factors, MAP, uterine artery L-PI and activin-A. In screening by a combination of maternal factors, biophysical and biochemical markers the estimated detection rates, at a 5% false-positive rate, were 88.5% (95% CI, 69.8-97.4%) for early PE, 46.7% (95% CI, 36.1-57.5%) for late PE and 35.3% (95% CI, 25.2-46.4%) for GH. CONCLUSION Combined biophysical and biochemical testing at 11-13 weeks could effectively identify women at high risk for subsequent development of hypertensive disorders in pregnancy.

Abstract
Preeclampsia is a leading cause of maternal and fetal/neonatal mortality and morbidity worldwide. The early identification of patients with an increased risk for preeclampsia is therefore one of the most important goals in obstetrics. The availability of highly sensitive and specific physiologic and biochemical markers would allow not only the detection of patients at risk but also permit a close surveillance, an exact diagnosis, timely intervention (e.g. lung maturation), as well as simplified recruitment for future studies looking at therapeutic medications and additional prospective markers. Today, several markers may offer the potential to be used, most likely in a combinatory analysis, as predictors or diagnostic tools. We present here the current knowledge on the biology of preeclampsia and review several biochemical markers which may be used to monitor preeclampsia in a future, that, we hope, is not to distant from today.

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.
