BACKGROUND: Severe preeclampsia is a disorder of pregnancy characterized by high blood pressure and significant proteinuria after 20 weeks gestation. Severe preeclampsia and eclampsia have considerable adverse impacts on maternal, fetal, and neonatal health especially in low-resource countries. Hypertensive disorders of pregnancy are the third leading cause of maternal deaths in Sub-Saharan Africa. Significant avoidable maternal and neonatal morbidity and mortality may result. OBJECTIVES: This study aimed 1) to determine the incidence of severe preeclampsia/eclampsia in a low-resource setting; 2) to determine the maternal complications of severe preeclampsia/eclampsia in a low-resource setting; 3) to determine the perinatal outcomes of severe preeclampsia/eclampsia in a low-resource setting...

OBJECTIVE: The aim of this study was to investigate whether massive proteinuria in preeclampsia is associated with maternal and fetal complications. METHODS: We retrospectively analyzed the clinical records of 233 patients who were diagnosed with preeclampsia. We divided the preeclamptic patients into three groups based on the amount of proteinuria: massive (≥5 g/24 hr), moderate (2 to 5 g/24 hr) and mild (<2 g/24 hr) proteinuria group. We analyzed the clinical characteristics and maternal and neonatal complications among three groups...

INTRODUCTION: Preeclampsia is a pregnancy complication characterized by high blood pressure and proteinuria. Endothelial dysfunction is a major theory suggested as its aetiology. It is caused by anti-angiogenic condition characterized by low Vascular Endothelial Growth Factor (VEGF). An estradiol metabolite, called 2-Methoxy Estradiol (2-ME), is produced with the help of Catechol-O-Methyltransferase (COMT). This substance has an important role in VEGF expression. A 2-ME is suppressed in women with preeclampsia...

Preeclampsia is a leading cause of maternal and perinatal morbidity and mortality globally and proteinuria can be one of the cardinal features of this disease. However, studies about the association of the amount of proteinuria and the severity of preeclampsia, and perinatal outcomes are limited. Data on 239 women with preeclampsia were retrospectively collected from a university teaching hospital from September 2011 to June 2013 and analysed. Data included all clinical parameters and proteinuria in a 24h urine collection...

REVIEW
Jessica R Jackson, Anthony R Gregg
Systematic reviews with meta-analysis represent the highest level of evidence used to guide clinical practice. The defining criteria used to diagnose preeclampsia have evolved, and will likely continue to evolve. Proteinuria is sufficient but not necessary when defining preeclampsia. Hypertension without proteinuria but with severe features is diagnostic. The methods used to measure urinary protein have changed. The gold standard remains the 24-hour urine test. The efficacy of low-dose aspirin in preventing preeclampsia is a function of baseline risk...

PROBLEM: The pathophysiology of preeclampsia (PE) is believed to be associated with a systemic inflammatory response, but few inflammatory markers are currently available to predict PE. Therefore, the aim of this study was to compare the serum delta neutrophil index (DNI) between normal and preeclamptic women. METHODS: Sixty-five patients with mild preeclampsia (mPE), 147 patients with severe preeclampsia (sPE), and 163 women with normal pregnancy were included in this study...

Preeclampsia (PE) is a serious pregnancy-related syndrome, which is characterized by gestational hypertension and proteinuria. The microRNA-93 (miR-93) is upregulated in the maternal plasma of patients with PE. However, the functional role of miR-93 in PE remains unknown. Here, we identified that miR-93 inhibits trophoblastic invasion, which is correlated with PE development. In immortalized trophoblast cell lines, transwell assay showed that miR-93 mimics significantly inhibited the migration and invasion of immortalized trophoblast cells, whereas miR-93 inhibitors significantly promoted cell migration and invasion...

BACKGROUND: Preeclampsia is a pregnancy complication which manifests as new-onset hypertension, proteinuria, and a spectrum of other symptoms. While the underlying causes are still a subject of much debate, it is commonly believed that placental ischemia is a central cause. The ischemic placenta secretes factors which are believed to be responsible for the maternal syndrome; most notably the anti-angiogenic protein soluble fms-like tyrosine kinase 1 (sFlt-1). We have reported that induction of the carbon monoxide (CO) producing protein heme oxygenase-1 restored angiogenic imbalance and reduced blood pressure in a rat model of placental ischemia, and that CO blocks hypoxia-induced sFlt-1 production from placental tissue in vitro...

Pregnancy-associated hypertensive disorders are leading causes of maternal and fetal mortality. These include: pre-pregnancy hypertension that persists throughout gestation (chronic/preexisting hypertension), de novo hypertension that is diagnosed after 20 weeks of gestation and resolves after birth (gestational hypertension), de novo hypertension that is diagnosed after 20 weeks of gestation with or without proteinuria and end-organ damage (preeclampsia and eclampsia), and chronic hypertension with superimposed preeclampsia during gestation...

INTRODUCTION: The etiology of preeclampsia is unclear. Fetal DNA is present in higher concentrations in the plasma of pregnant women suffering from preeclampsia than in the plasma of healthy pregnant women. A previously published study has shown that human fetal DNA injected into pregnant mice induces preeclampsia-like symptoms when administered between gestation days 10-14. The aim of our experiment was to determine whether or not similar effects would be induced by administration of human and mouse fetal DNA, as well as mouse adult DNA and lipopolysaccharide during late pregnancy in the mouse...

Preeclampsia (PE) is a pregnancy-specific disorder characterized by new-onset hypertension and proteinuria that occurs after 20 weeks of gestation. It involves several organs and continues to be a leading cause of maternal and perinatal morbidity and mortality worldwide. Shallow trophoblast invasion is a common pathological feature of PE. Transthyretin (TTR) is a 56-kDa homotetrameric protein that binds thyroid hormone and retinol binding protein. Dysregulated TTR expression has been found in cases of PE. The aim of the present study was to determine the functional role of TTR in the migration and invasion of JEG-3 choriocarcinoma cells...

Preeclampsia (PE) is a protean syndrome causing a transitory kidney disease, characterised by hypertension and proteinuria, ultimately reversible after delivery. Its prevalence is variously estimated, from 3 to 5% to 10% if all the related disorders, including also pregnancy-induced hypertension (PIH) and HELLP syndrome (haemolysis, increase in liver enzyme, low platelets) are included. Both nephrologists and obstetricians are involved in the management of the disease, according to different protocols, and the clinical management, as well as the role for each specialty, differs worldwide...

Preeclampsia is a devastating complication of pregnancy characterized by late-gestation hypertension and proteinuria. Because the only definitive treatment is delivery of the fetus and placenta, preeclampsia contributes to increased morbidity and mortality of both mother and fetus. The BPH/5 mouse model, which spontaneously develops a syndrome strikingly similar to preeclampsia, displays excessive inflammation and suppression of inflammation improves pregnancy outcomes. During early pregnancy, decidual macrophages play an important role in promoting maternal tolerance to fetal antigens and regulating tissue remodeling, two functions that are critical for normal placental development...

Preeclampsia is characterized by hypertension, proteinuria, suppression of plasma renin-angiotensin-aldosterone, and impaired urine sodium excretion. Aberrantly filtered plasmin in urine may activate proteolytically the γ-subunit of the epithelial sodium channel (ENaC) and promote Na(+) reabsorption and urine K(+) loss. Plasma and urine was sampled from patients with preeclampsia, healthy pregnant controls and non-pregnant women, and from patients with nephrostomy catheters. Aldosterone concentration, urine plasminogen, and protein were determined...
