BACKGROUND: Preeclampsia is a major pregnancy complication with adverse short- and long-term implications for both the mother and baby. Screening for preeclampsia at 11-13 weeks' gestation by a combination of maternal demographic characteristics and medical history with measurements of biomarkers can identify about 75% of women that develop preterm-preeclampsia with delivery at <37 weeks' gestation and 90% of those with early-preeclampsia at <32 weeks, at a screen positive rate of 10%...

BACKGROUND: Preeclampsia is a major hypertensive disease caused by pregnancy, inducing proteinuria and increased blood pressure starting from the second half of pregnancy (early preeclampsia) or near the end of pregnancy (late preeclampsia). Pre-symptomatic diagnosis would allow for therapeutic interventions, such as with low-dose aspirin. Among non-invasive methods to explore organ physiology, Doppler ultrasonography (US) and functional blood oxygenation level-dependent (BOLD) MRI (which do not need radioactive contrast agents such as gadolinium) can be used in pregnant women...

The benefit of the early administration of aspirin to reduce preterm pre-eclampsia among screened positive European women from multivariate algorithmic approach (ASPRE trial) has opened an intense debate on the feasibility of universal screening. This review aims to assess the new perspectives in the combined screening of pre-eclampsia in the first trimester of pregnancy and the chances for prevention using low-dose aspirin with special emphasis on the particularities of the Asian population. PubMed, CENTRAL and Embase databases were searched from inception until 15 November 2017 using combinations of the search terms: preeclampsia, Asian, prenatal screening, early prediction, ultrasonography, pregnancy, biomarker, mean arterial pressure, soluble fms-like tyrosine kinase-1, placental growth factor, pregnancy-associated plasma protein-A and pulsatility index...

Reduced expression of peroxisome proliferator-activated receptor γ (PPARγ) in the placenta was found in women with severe preeclampsia. Aspirin is currently used as the only recommended intervention in pregnancies for prevention of preeclampsia. In this study, we aimed to investigate whether aspirin could attenuate PPARγ inhibitor (T0070907)-induced preeclampsia and its impact on expression of PPARγ. Sixty Sprague-Dawley rats were used and treated with different doses of aspirin (0, 1, and 1.5 mg/kg) in presence or absence of PPARγ antagonist, T0070907...

OBJECTIVE: Low-dose aspirin (LDA) therapy has been found to be effective in preventing the development of early-onset preeclampsia. However, its effect on late-onset preeclampsia has not been described. Our study was aimed at determining if LDA therapy prescribed from early in pregnancy modified the severity of late-onset preeclampsia. MATERIALS AND METHODS: A retrospective analysis of all women who were screened for early-onset preeclampsia at 11-13+6 weeks' gestation between April 2012 and October 2014 at our institution, and who subsequently developed late-onset preeclampsia...

OBJECTIVE DATA: Impaired placentation in the first 16 weeks of pregnancy is associated with increased risk of subsequent development of preeclampsia, birth of small-for-gestational-age neonates, and placental abruption. Previous studies reported that prophylactic use of aspirin reduces the risk of preeclampsia and small-for-gestational-age neonates with no significant effect on placental abruption. However, meta-analyses of randomized controlled trials that examined the effect of aspirin in relation to gestational age at onset of therapy and dosage of the drug reported that significant reduction in the risk of preeclampsia and small-for-gestational-age neonates is achieved only if the onset of treatment is at ≤16 weeks of gestation and the daily dosage of the drug is ≥100 mg...

OBJECTIVE: First-trimester low concentration of pregnancy-associated plasma protein A (PAPP-A) has been associated with adverse perinatal outcomes in high-risk populations. This study aimed to estimate the ability of PAPP-A to identify adverse outcomes in a low-risk population. METHODS: The study investigators recruited nulliparous women with singleton pregnancy at their 11-13-week ultrasound scan. Serum samples were collected, and maternal PAPP-A concentration was measured using the B ⋅ R ⋅ A ⋅ H ⋅ M ⋅ S PAPP-A KRYPTOR (ThermoFisher Scientific, Hennigsdorf, Germany) automated assay...

Fetal growth restriction and related placental pathologies such as preeclampsia, stillbirth, and placental abruption are believed to arise in early pregnancy when inadequate remodeling of the maternal spiral arteries leads to persistent high-resistance and low-flow uteroplacental circulation. The consequent placental ischaemia, reperfusion injury, and oxidative stress are associated with an imbalance in angiogenic/antiangiogenic factors. Many interventions have centered on the prevention and/or treatment of preeclampsia with results pertaining to fetal growth restriction and small-for-gestational-age pregnancy often included as secondary outcomes because of the common pathophysiology...

OBJECTIVE DATA: Metaanalyses of randomized controlled trials have reported contradictory results about the effect of aspirin in the prevention of preeclampsia, both in terms of the gestational age at the onset of treatment and the dose of the drug. The controversy may be resolved by a metaanalysis that includes several recently published trials and particularly the large Combined Multimarker Screening and Randomized Patient Treatment with Aspirin for Evidence-based Preeclampsia Prevention trial and by examination of whether there is a difference of the effect of aspirin on preterm vs term preeclampsia...

Early administration of low dose acetyl salicylic acid (Aspirin) in high risk women reduces the risk of early onset preeclampsia. This study aims to investigate the effect of aspirin on trophoblast integration and the its effect on angiogenic and invasive pathways in an in-vitro model of preeclampsia. Red fluorescent-labeled human uterine myometrial microvascular endothelial cells (UtMVECs) were seeded on matrigel to form endothelial networks. Green fluorescent-labeled trophoblastic HTR-8/SVneo cells were co-cultured with the endothelial networks with/without TNF-a (0...

Aspirin is currently the most widely prescribed treatment in the prevention of cardiovascular complications. The indications for the use of aspirin during pregnancy are, however, the subject of much controversy. Since the first evidence of the obstetric efficacy of aspirin in 1985, numerous studies have tried to determine the effect of low-dose aspirin on the incidence of preeclampsia, with very controversial results. Large meta-analyses including individual patient data have demonstrated that aspirin is effective in preventing preeclampsia in high-risk patients, mainly those with a history of preeclampsia...

Hypertensive disorders affect about one third of all people aged 20 and above, and are treated with anti-hypertensive drugs. Preeclampsia (PE) is one form of such disorders that only develops during pregnancy. It affects ten million pregnant women globally and additionally causes fetal loss and major newborn disabilities. The syndrome's origin is multifactorial, and anti-hypertensive drugs are ineffective in treating it. Biomarkers are helpful for predict its development. Generic drugs, such as low dose aspirin, were proven effective in preventing preterm PE...

INTRODUCTION: There is recent evidence that prophylaxis with 150 mg of aspirin given before 14-16 weeks significantly reduces preeclampsia rates and may improve pregnancy outcome. We conducted an observational study that investigates the effect of low-dose aspirin initiated early in pregnancy or in preconception on functional parameters assessed at 11-14 weeks. MATERIALS AND METHODS: We have retrospectively selected 128 pregnant women that presented for the first trimester screening for aneuploidies between 11+0 and 13+6 weeks of gestation and received low-dose aspirin before 14 weeks...
