Abstract
OBJECTIVES To ascertain whether abnormalities in neonatal head circumference and/or body weight are associated with levels of angiogenic/antiangiogenic factors in the maternal and cord blood of pregnancies with a congenital heart defect (CHD) and to assess whether the specific type of CHD influences this association. METHODS This was a multicenter case-control study of women carrying a fetus with major CHD. Recruitment was carried out between June 2010 and July 2018 at four tertiary care hospitals in Spain. Maternal venous blood was drawn at study inclusion and at delivery. Cord blood samples were obtained at birth when possible. Placental growth factor (PlGF), soluble fms-like tyrosine kinase-1 (sFlt-1) and soluble endoglin (sEng) were measured in maternal and cord blood. Biomarker concentrations in the maternal blood were expressed as multiples of the median (MoM). RESULTS PlGF, sFlt-1 and sEng levels were measured in the maternal blood in 237 cases with CHD and 260 healthy controls, and in the cord blood in 150 cases and 56 controls. Compared with controls, median PlGF MoM in maternal blood was significantly lower in the CHD group (0.959 vs 1.022; P < 0.0001), while median sFlt-1/PlGF ratio MoM was significantly higher (1.032 vs 0.974; P = 0.0085) and no difference was observed in sEng MoM (0.981 vs 1.011; P = 0.4673). Levels of sFlt-1 and sEng were significantly higher in cord blood obtained from fetuses with CHD compared to controls (mean ± standard error of the mean, 447 ± 51 vs 264 ± 20 pg/mL; P = 0.0470 and 8.30 ± 0.92 vs 5.69 ± 0.34 ng/mL; P = 0.0430, respectively). Concentrations of sFlt-1 and the sFlt-1/PlGF ratio in the maternal blood at study inclusion were associated negatively with birth weight and head circumference in the CHD group. The type of CHD anomaly (valvular, conotruncal or left ventricular outflow tract obstruction) did not appear to alter these findings. CONCLUSIONS Pregnancies with fetal CHD have an antiangiogenic profile in maternal and cord blood. This imbalance is adversely associated with neonatal head circumference and birth weight. © 2023 International Society of Ultrasound in Obstetrics and Gynecology.

Abstract
OBJECTIVE To develop a model for the prediction of adverse perinatal outcome in growth-restricted fetuses requiring delivery before 28 weeks in order to provide individualized patient counseling. METHODS This was a retrospective multicenter cohort study of singleton pregnancies with antenatal suspicion of fetal growth restriction requiring delivery before 28 weeks' gestation between January 2010 and January 2020 in six tertiary public hospitals in the Barcelona area, Spain. Separate predictive models for mortality only and mortality or severe neurological morbidity were created using logistic regression from variables available antenatally. For each model, predictive performance was evaluated using receiver-operating-characteristics (ROC)-curve analysis. Predictive models were validated externally in an additional cohort of growth-restricted fetuses from another public tertiary hospital with the same inclusion and exclusion criteria. RESULTS A total of 110 cases were included. The neonatal mortality rate was 37.3% and, among the survivors, the rate of severe neurological morbidity was 21.7%. The following factors were retained in the multivariate analysis as significant predictors of mortality: magnesium sulfate neuroprotection, gestational age at birth, estimated fetal weight, male sex and Doppler stage. This model had a significantly higher area under the ROC curve (AUC) compared with a model including only gestational age at birth (0.810 (95% CI, 0.730-0.889) vs 0.695 (95% CI, 0.594-0.795); P = 0.016). At a 20% false-positive rate, the model showed a sensitivity, negative predictive value and positive predictive value of 66%, 80% and 66%, respectively. For the prediction of the composite adverse outcome (mortality or severe neurological morbidity), the model included: gestational age at birth, male sex and Doppler stage. This model had a significantly higher AUC compared with a model including only gestational age at birth (0.810 (95% CI, 0.731-0.892) vs 0.689 (95% CI, 0.588-0.799); P = 0.017). At a 20% false-positive rate, the model showed a sensitivity, negative predictive value and positive predictive value of 55%, 63% and 74%, respectively. External validation of both models yielded similar AUCs that did not differ significantly from those obtained in the original sample. CONCLUSIONS Estimated fetal weight, fetal sex and Doppler stage can be combined with gestational age to improve the prediction of death or severe neurological sequelae in growth-restricted fetuses requiring delivery before 28 weeks. This approach may be useful for parental counseling and decision-making. © 2023 International Society of Ultrasound in Obstetrics and Gynecology.

Abstract
Background Congenital heart disease (CHD) is the most prevalent congenital malformation affecting 1 in 100 newborns. While advances in early diagnosis and postnatal management have increased survival in CHD children, worrying long-term outcomes, particularly neurodevelopmental disability, have emerged as a key prognostic factor in the counseling of these pregnancies. Methods Eligible participants are women presenting at 20 to < 37 weeks of gestation carrying a fetus with CHD. Maternal/neonatal recordings are performed at regular intervals, from the fetal period to 24 months of age, and include: placental and fetal hemodynamics, fetal brain magnetic resonance imaging (MRI), functional echocardiography, cerebral oxymetry, electroencephalography and serum neurological and cardiac biomarkers. Neurodevelopmental assessment is planned at 12 months of age using the ages and stages questionnaire (ASQ) and at 24 months of age with the Bayley-III test. Target recruitment is at least 150 cases classified in three groups according to three main severe CHD groups: transposition of great arteries (TGA), Tetralogy of Fallot (TOF) and Left Ventricular Outflow Tract Obstruction (LVOTO). Discussion The results of NEURO-HEART study will provide the most comprehensive knowledge until date of children’s neurologic prognosis in CHD and will have the potential for developing future clinical decisive tools and improving preventive strategies in CHD. Trial registration NCT02996630, on 4th December 2016 (retrospectively registered).

Abstract
OBJECTIVES The soluble fms-like tyrosine kinase-1 (sFlt-1) to placental growth factor (PlGF) ratio is generally elevated some time before and at the clinical onset of pre-eclampsia. The PROGNOSIS study validated a sFlt-1/PlGF ratio cut-off of ≤ 38 to rule out the onset of pre-eclampsia within 1 week of testing in women with suspected disease. The aim of this study was to assess the predictive value of the sFlt-1/PlGF ratio to rule out the onset of pre-eclampsia for up to 4 weeks, and to assess the value of repeat measurements. METHODS This was an exploratory post-hoc analysis of data from the PROGNOSIS study performed in pregnant women aged ≥ 18 years with suspected pre-eclampsia, who were at 24 + 0 to 36 + 6 weeks' gestation at their first clinic visit. Serum samples were collected at the first visit and weekly thereafter. sFlt-1 and PlGF levels were measured using Elecsys® sFlt-1 and PlGF immunoassays. Whether the sFlt-1/PlGF ratio cut-off of ≤ 38 used to rule out the onset of pre-eclampsia within 1 week could predict the absence of pre-eclampsia 2, 3, and 4 weeks post-baseline was assessed. The value of repeat sFlt-1/PlGF testing was assessed by examining the difference in sFlt-1/PlGF ratio 2 and 3 weeks after the first measurement in women with, and those without, pre-eclampsia or adverse fetal outcome. RESULTS On analysis of 550 women, sFlt-1/PlGF ratio ≤ 38 ruled out the onset of pre-eclampsia 2 and 3 weeks post-baseline with high negative predictive values (NPV) of 97.9% and 95.7%, respectively. The onset of pre-eclampsia within 4 weeks was ruled out with a high NPV (94.3%) and high sensitivity and specificity (66.2% and 83.1%, respectively). Compared with women who did not develop pre-eclampsia, those who developed pre-eclampsia had significantly larger median increases in sFlt-1/PlGF ratio at 2 weeks (∆, 31.22 vs 1.45; P < 0.001) and at 3 weeks (∆, 48.97 vs 2.39; P < 0.001) after their initial visit. Women who developed pre-eclampsia and/or adverse fetal outcome compared with those who did not had a significantly greater median increase in sFlt-1/PlGF ratio over the same period (∆, 21.22 vs 1.40; P < 0.001 at 2 weeks; ∆, 34.95 vs 2.30; P < 0.001 at 3 weeks). CONCLUSION The Elecsys® immunoassay sFlt-1/PlGF ratio can help to rule out the onset of pre-eclampsia for 4 weeks in women with suspected pre-eclampsia. © 2018 The Authors.

Abstract
OBJECTIVE To assess potential differences in the expression of antiangiogenic and angiogenic factors and of genes associated with chronic hypoxia in cerebral tissue of euploid fetuses with congenital heart disease (CHD) vs those without. METHODS Cerebral tissue was obtained from 15 fetuses with CHD and 12 control fetuses that had undergone termination of pregnancy. Expression profiles of the antiangiogenic factor soluble fms-like tyrosine kinase-1 (sFlt-1), the angiogenic vascular endothelial growth factor-A (VEGF-A) and placental growth factor (PlGF), and of genes associated with chronic hypoxia were determined by real-time polymerase chain reaction in tissue from the frontal cortex and the basal ganglia of the fetuses. RESULTS Expression of sFlt-1 was 48% higher in the frontal cortex (P = 0.0431) and 72% higher in the basal ganglia (P = 0.0369) of CHD fetuses compared with controls. The expression of VEGF-A was 60% higher (P = 0.0432) and that of hypoxia-inducible factor 2-alpha was 98% higher (P = 0.0456) in the basal ganglia of CHD fetuses compared with controls. No significant differences were observed between the two groups in the expression of PlGF and hypoxia-inducible factor 1-alpha. CONCLUSION An overall dysregulation of angiogenesis with a net balance towards an antiangiogenic environment was observed in the cerebral tissue of fetuses with CHD, suggesting that these fetuses may have an intrinsic angiogenic impairment that could contribute to impaired brain perfusion and abnormal neurological development later in life.

Abstract
Objectives: The aim of this study was to evaluate the relationships between brain injury biomarkers in intrauterine growth-restricted (IUGR) infants (S100B and neuron-specific enolase (NSE)) and neurodevelopment at 2 years of age. Methods: This prospective case-control study was a cooperative effort among Spanish Maternal and Child Health Network (Retic SAMID) hospitals. At inclusion, biometry for estimated fetal weight and feto-placental Doppler variables were measured for each infant. Maternal venous blood and fetal umbilical arterial blood samples were collected at the time of delivery and neural injury markers S100B and NSE concentrations were measured. Neurodevelopment was evaluated at 2 years of age using the Bayley Scales of Infant and Toddler Development, third edition (Bayley-III). Results: Fifty six pregnancies were included. Thirty-one infants were classified as IUGR and 25 as non-IUGR. Neurodevelopmental evaluation at 2 years of age indicated that there were no between-group differences for any of the tests. For all patients in both groups, we found statistically significant inverse relationships between the concentrations of NSE in the cord blood and the results of the cognitive test (r = -271, p = .042), fine motor subtest (r = -280, p = .036), and social-emotional test (r = -349, p = .015). We also found statistically significant differences between the concentrations of S100B in the cord blood and the results of the cognitive test (r = -306, p = .022) and expressive communication subtest (r = -304, p = .023). For the IUGR group, we found a significant inverse relationship between the concentrations of S100B in the maternal serum and the results of adaptive behavior test (p < .05). In the non-IUGR group, we found statistically significant inverse relationships between the concentration of NSE in the cord blood and the results of the fine motor subtest (r = -446, p = .025) and social-emotional test (r = -489, p = .021). The difference between the concentration of S100B in the cord blood and the language composite score was also statistically significant (p = .038). Conclusions: At 2 years of age, the concentrations of NSE and S100B were higher in the non-IUGR and IUGR groups with the worst scores for some areas of neurodevelopmental evaluation. The value of these biomarkers for prognostic neurodevelopmental use requires further investigation for both non-IUGR and IUGR infants.

Abstract
OBJECTIVES To determine the longitudinal behavior of fetal biometric measures and cerebroplacental hemodynamics throughout gestation in fetuses with congenital heart disease (CHD). METHODS Fetal biometry and Doppler hemodynamics (uterine artery (UtA), umbilical artery (UA) and fetal middle cerebral artery (MCA)) were measured serially in a cohort of consecutive fetuses diagnosed with CHD. Evaluations were made at various time points, from diagnosis (20-25 weeks) to delivery, with at least two measurements per fetus that were at least 2 weeks apart. Fetuses were classified into three groups according to the pattern of blood supply to the brain (placental vs systemic) that would be expected on the basis of the type of CHD. All parameters were transformed into Z-scores. A linear mixed model to analyze repeated measurements was constructed for each parameter to assess its behavior throughout gestation. RESULTS Four hundred and forty-four ultrasound examinations were performed in 119 CHD fetuses, with a median of two measurements per fetus. The fetuses presented a small head at diagnosis (biparietal diameter (BPD) Z-score, -1.32 ± 0.99; head circumference (HC) Z-score, -0.79 ± 1.02), which remained small throughout gestation. UtA and UA pulsatility indices (PI) showed a significant increase towards the end of pregnancy, whereas no significant changes were observed in MCA-PI or cerebroplacental ratio (CPR) with gestational age. Both MCA and CPR presented significant differences in longitudinal behavior between CHD groups, while BPD and HC did not. CONCLUSIONS CHD fetuses have a relatively small head from the second trimester of pregnancy, regardless of the type of CHD anomaly, and increasing resistance in the UtA and UA as pregnancy progresses, suggestive of increasing degree of placental impairment. Our findings indicate the early onset of mechanisms that could lead to poorer neurodevelopment later in life. Copyright © 2016 ISUOG. Published by John Wiley & Sons Ltd.

Abstract
OBJECTIVES To ascertain whether screening for pre-eclampsia (PE) and intrauterine growth restriction (IUGR) by uterine artery (UtA) Doppler in the second trimester of pregnancy and targeted surveillance improve maternal and perinatal outcomes in an unselected population. METHODS This was a multicenter randomized open-label controlled trial. At the routine second-trimester anomaly scan, women were assigned randomly to UtA Doppler or non-Doppler groups. Women with abnormal UtA Doppler were offered intensive surveillance at high-risk clinics of the participating centers with visits every 4 weeks that included measurement of maternal blood pressure, dipstick proteinuria, fetal growth and Doppler examination. The primary outcome was a composite score for perinatal complications, defined as the presence of any of the following: PE, IUGR, spontaneous labor < 37 weeks' gestation, placental abruption, stillbirth, gestational hypertension, admission to neonatal intensive care unit and neonatal complications. Secondary outcomes were a composite score for maternal complications (disseminated intravascular coagulation, maternal mortality, postpartum hemorrhage, pulmonary edema, pulmonary embolism, sepsis), and medical interventions (for example, corticosteroid administration and induction of labor) in patients developing placenta-related complications. RESULTS In total, 11 667 women were included in the study. Overall, PE occurred in 348 (3.0%) cases, early-onset PE in 48 (0.4%), IUGR in 722 (6.2%), early-onset IUGR in 93 (0.8%) and early-onset PE with IUGR in 32 (0.3%). UtA mean pulsatility index > 90(th) percentile was able to detect 59% of early-onset PE and 60% of early-onset IUGR with a false-positive rate of 11.1%. When perinatal and maternal data according to assigned group (UtA Doppler vs non-Doppler) were compared, no differences were found in perinatal or maternal complications. However, screened patients had more medical interventions, such as corticosteroid administration (relative risk (RR), 1.79 (95% CI, 1.4-2.3)) and induction of labor for IUGR (RR, 1.36 (95% CI, 1.07-1.72)). In women developing PE or IUGR, there was a trend towards fewer maternal complications (RR, 0.46 (95% CI, 0.19-1.11)). CONCLUSIONS Routine second-trimester UtA Doppler ultrasound in an unselected population identifies approximately 60% of women at risk for placental complications; however, application of this screening test failed to improve short-term maternal and neonatal morbidity and mortality.

Abstract
The maternal immune system needs to adapt to tolerate the semi-allogeneic conceptus. Since maternal allo-reactive lymphocytes are not fully depleted, other local/systemic mechanisms play a key role in altering the immune response. The Th1/Th2 cytokine balance is not essential for a pregnancy to be normal. The immune cells, CD4+CD25+Foxp3+, also known as regulatory T cells (Tregs), step in to regulate the allo-reactive Th1 cells. In this review we discuss the role of Tregs in foeto-maternal immune tolerance and in recurrent miscarriage as well as their potential use as a new target for infertility treatment. Animal and human experiments showed Treg cell number and/or function to be diminished in miscarriages. Murine miscarriage can be prevented by transferring Tregs from normal pregnant mice. Tregs at the maternal-fetal interface prevented fetal allo-rejection by creating a "tolerant" microenvironment characterised by the expression of IL-10, TGF-β and haem oxygenase isoform 1 (HO-1) rather than by lowering Th1 cytokines. Tregs increase placental HO-1. In turn, HO-1 may lead to up-regulation of TGF-β, IL-10 and CTLA-4. In vivo experiments showed Tregs sensitisation from paternal antigens to be essential for maternal-fetal tolerance. Tregs increase throughout pregnancy and diminish in late puerperium. Recent data also support the capacity of Tregs to block maternal effector T cells, thereby reducing the maternal-fetal pathological responses to paternal antigens. These findings also permit us to consider new strategies for improving pregnancy outcomes, i.e., anti-TNF blockers and granulocyte-colony stimulating factors as well as novel approaches to therapeutically exploiting Treg + cell memory.

Abstract
OBJECTIVE To investigate the relationship between fetal heart defects and maternal serum placental growth factor (PlGF), a marker of placental angiogenesis. METHODS Maternal serum PlGF, pregnancy-associated plasma protein-A (PAPP-A) and uterine artery pulsatility index (UtA-PI) at 11-13 weeks' gestation were compared in 68 cases of isolated fetal major heart defects and 340 normal controls. Variables were converted into multiples of the median (MoM) after adjustment for gestational age, maternal age, racial origin, weight, parity and method of conception, and then compared between groups. The cardiac defects included 11 cases of obstruction of the left ventricular outflow tract (LVOT), 25 conotruncal abnormalities and 32 valve defects. RESULTS The median PlGF-MoM in the heart defect group was lower than in controls (0.80 (interquartile range (IQR), 0.57-1.08) vs 1.00 (IQR, 0.79-1.32); P < 0.0001). Low PlGF levels were observed in the presence of conotruncal and valve defects but not in the presence of LVOT defects. There was no significant difference between the group with fetal heart defects and controls in PAPP-A-MoM (0.95 (IQR, 0.68-1.28) vs 1.01 (IQR, 0.70-1.39); P = 0.292) or UtA-PI-MoM (1.01 (IQR, 0.84-1.28) vs 0.99 (IQR, 0.80-1.20); P = 0.396). CONCLUSION In pregnancies with isolated fetal heart defects there is evidence of impaired placental angiogenesis in the absence of impaired placental perfusion and function.

Abstract
OBJECTIVE To examine the relationship between prenatal umbilical artery (UA) and internal carotid artery (ICA) Doppler findings and cognitive development at 3 and 6 years in low-birth-weight children. METHODS This was a study of 209 low-birth-weight (< 10(th) centile) children born after 28 gestational weeks with UA resistance index (RI) measured within 2 weeks before delivery. Children with normal UA- and ICA-RI were defined as small-for-gestational age (SGA) and those with abnormal UA or ICA Doppler findings as having fetal growth restriction (FGR). Cognitive ability at 3 and 6 years' corrected age was assessed using the fourth edition of the Stanford-Binet Intelligence Scale (SBIS) and compared between SGA and FGR groups. An SBIS score < 85 was considered to indicate delayed development. RESULTS The median gestational age at diagnosis of abnormal fetal growth was 36.6 (range, 28-41) weeks. There were 87 (41.6%) children classified as having FGR and 122 (58.4%) as SGA. The mean global SBIS score at 3 years was 109.4 (SD, 22.8) and at 6 years it was 110.5 (SD, 13.9). Overall, 22 (10.5%) children had delayed development at 3 years. Total SBIS scores and individual domain scores did not differ between FGR and SGA groups at 3 or 6 years and similar proportions in each group had delayed development. CONCLUSION Abnormal prenatal UA and ICA Doppler findings are not associated with lower developmental scores in low-birth-weight children delivered in the third trimester of pregnancy.

Abstract
BACKGROUND Systemic autoimmune/granulomatous adverse reactions related to biomaterials other than silicone have rarely been reported. AIM The aim of this paper is to communicate the cases of autoimmune/inflammatory syndrome induced by adjuvants (ASIA) in a study of Spanish patients suffering from inflammatory disorders related to biomaterial injections other than silicone, principally hyaluronic acid, acrylamides or methacrylate compounds. METHODS The authors performed a retrospective analysis of the clinical, laboratory, histopathology and follow-up of a cohort of 250 cases of patients suffering from inflammatory/autoimmune disorders related to bioimplant injections. RESULTS Of these 250 cases, patients with adverse reactions related to silicone injections (n = 65) were excluded. Of the remaining 185, 15 cases (8%) had systemic or distant and multiple complaints that could be categorized as ASIA. In all but four patients, inflammatory features at the implantation site preceded distant or systemic manifestations. Abnormal blood tests were common. Eleven cases (73.3%) with inflammatory localized nodules and panniculitis evolved into a variety of disorders, namely, primary biliary cirrhosis, Sjögren's syndrome, sarcoidosis, human adjuvant disease and inflammatory polyradiculopathy. Four cases presented primarily with systemic autoimmune disorders. CONCLUSIONS Infrequently, biomaterials other than silicone can provoke local inflammatory adverse reactions that may evolve into systemic autoimmune and/or granulomatous disorders. Whether or not these biomaterials act as an adjuvant, they could be included in the ASIA category.

Abstract
Mirror syndrome is a rare condition that involves fetal hydrops, placentomegaly and severe maternal edema. The pathogenesis of this syndrome mimics endothelial dysfunction observed in pre-eclampsia. We report a case of maternal mirror syndrome caused by bilateral fetal hydrothorax that resolved after intrauterine pleuroamniotic shunt placement. At the time of the clinical manifestation there was an antiangiogenic state similar to that seen in pre-eclampsia, which resolved after fetal treatment. Our findings suggest that mirror syndrome is a manifestation of a broad spectrum of pathological conditions that induces an antiangiogenic state.

Abstract
BACKGROUND The risk of pre-eclampsia (PE) increases in twin pregnancies, especially when assisted reproduction technologies (ART) are used. The aim of this study was to assess angiogenic/anti-angiogenic factors in maternal serum in the first trimester of twin pregnancies and establish if the mode of conception influences angiogenic status. METHODS This prospective study enrolled women with twin (n = 61) and singleton (n = 50) pregnancies. Dichorionic twin pregnancies were divided into two groups according to their mode of conception. Singleton pregnancies were used as the control group. Soluble fms-like tyrosine kinase (sFlt-1), free placental growth factor (PlGF) and soluble endoglin (sEng) concentrations were measured in the first trimester maternal serum. RESULTS In the first trimester, women with twin pregnancies had higher serum concentrations of the anti-angiogenic factor sFlt-1 than that with singleton pregnancies (3924 ± 250 versus 2426 ± 162 pg/ml, respectively; P < 0.001). Maternal serum PlGF concentrations were lower in singleton pregnancies than those in twin pregnancies (37 ± 3.7 versus 59 ± 5.6, respectively; P < 0.001). Serum concentrations of sFlt-1 were higher in twin pregnancies conceived by ART than those in spontaneous twin pregnancies (4313 ± 389 versus 3522 ± 300 pg/ml, respectively; P < 0.05). No differences between groups were observed for sEng. CONCLUSIONS In the first trimester, twin pregnancies conceived using ART showed a heightened anti-angiogenic status that could explain the increased risk of PE in these cases.

Abstract
Objective: To study the prevalence and clinical usefulness of antiphospholipid antibodies in different preeclampsia subsets. Design: Observational cross-sectional study. Setting: Tertiary teaching hospital. Patients: Ninety-nine women with preeclampsia versus 83 healthy pregnant women as controls. Interventions: We analysed anticardiolipin IgG/IgM, anti-ß2glycoprotein IgG/IgM, antiphosphatidylserine IgG/IgM, antiAnnexin-A5 IgG/IgM, and lupus anticoagulant. Main outcome measure: Comparison of antiphospholipid antibody positivity between groups. Results: Antiphospholipid antibody prevalence was 14.14% in the study group vs. 7.23% in controls. Excluding antiAnnexin-A5-positive women, overall antiphospholipid prevalence was 13.19% vs. 3.61% ( p = 0.034). Only IgM-anticardiolipin positivity showed significant differences between preeclampsia group and controls (8.1% vs. 1.20%, p = 0.041). Comparing a severe preeclampsia subset vs. controls, we obtained these significant results: for two or more positive antiphospholipid tests: 9.09% vs. 1.20 ( p = 0.037); IgM-anticardiolipin 10.91% vs. 1.20% ( p = 0.016); IgG/IgM-anti-ß2glycoprotein-I 10.91% vs. 1.90% ( p = 0.016), IgM-anti-ß2glycoprotein-I 9.09% vs.1.20 ( p = 0.037). When comparing early-onset preeclampsia vs. controls we found IgM-anticardiolipin 11.11% vs. 1.20% ( p = 0.029). Conclusions: Prevalence of antiphospholipid antibodies in preeclampsia patients is twice that in healthy pregnant women. Multipositive aPL test, IgM-anticardiolipin and IgM-anti-ß2glycoprotein-I isotypes showed an association with severe and early-onset preeclampsia. Larger studies are needed to establish the usefulness of antiphospholipid tests as risk markers for severe and early onset preeclampsia.

Abstract
OBJECTIVES To investigate potential differences in the prediction of early- vs. late-onset pre-eclampsia and/or intrauterine growth restriction (PE/IUGR) by second-trimester uterine artery Doppler examination, and measurement of maternal serum placental growth factor (PlGF) and soluble fms-like tyrosine kinase 1 (sFlt1). METHODS Uterine artery mean pulsatility index (PI) and maternal serum PlGF and sFlt1 levels were measured at 24 weeks of gestation in 76 healthy pregnant women and 38 cases of PE/IUGR, of which 19 were defined as early onset (< 32 weeks). RESULTS For a specificity of 95%, the sensitivities of uterine artery mean PI, PlGF and sFlt1 for early-onset PE/IUGR were 47.4%, 84.4% and 36.8%, respectively. When combining uterine artery Doppler with PlGF, the sensitivity for identifying early-onset PE/IUGR was 89.5% with a specificity of 95%. Conversely, the sensitivity for late-onset PE/IUGR was below 11% for all parameters analyzed. CONCLUSIONS Angiogenic factors and uterine artery Doppler evaluation may be useful second-trimester screening tests for early-onset, but not late-onset, PE/IUGR.
