We tested the hypothesis that angiotensin-converting enzyme (ACE) and angiotensinogen gene polymorphism influence the incidence, development and outcome of preeclampsia. Subjects were recruited from 90 Korean patients with preeclampsia during pregnancy and 98 age-matched controls. After isolation of DNA, polymerase chain reactions (PCR) were carried out to detect polymorphism of the ACE and ang...

The aim of this study was to investigate the role of neutrophil-derived reactive oxygen species on endothelial cell dysfunction in preeclampsia. We first assessed the correlation between nitrite and superoxide anion production in normal nonpregnant (n=10), normal pregnant (n=15), and preeclamptic women (n=12). We then examined neutrophil-mediated oxygen radical damage to human umbilical vein en...

BACKGROUND Preeclampsia is a severe pregnancy disorder often complicated by reduced fetal growth or preterm delivery and is associated with long-term maternal morbidity and mortality. We aimed to assess the association between preeclampsia phenotypes and risk of subsequent coronary heart disease and maternal cardiovascular mortality. METHODS AND RESULTS Women aged 16 to 49 years who gave birt...

Preeclampsia, a cardiovascular disorder of late pregnancy, is characterized as a low-renin hypertensive state relative to normotensive pregnancy. Because other nonpregnant low-renin hypertensive disorders often exhibit and are occasionally dependent on elevated arginine vasopressin (AVP) secretion, we hypothesized a possible use for plasma AVP measurements in the prediction of preeclampsia. Cop...

Background. To assess the ability of mid-trimester sFlt-1/PlGF ratio for prediction of preeclampsia in two different Arabic populations. Methods. This study measured levels of sFlt-1, PlGF, and sFlt-1/PlGF ratio at midtrimester in 83 patients who developed preeclampsia with contemporary 250 matched controls. Results. Women subsequently developed preeclampsia had significantly lower PlGF levels ...

Preeclampsia is a heterogeneous syndrome affecting 3% to 5% of all pregnancies. An imbalance of the antiangiogenic and proangiogenic factors, soluble receptor fms-like tyrosine kinase 1 and placental growth factor (PGF), is thought to contribute to the pathophysiology of preeclampsia. Maternal plasma PGF and soluble receptor fms-like tyrosine kinase 1 were quantified by specific immunoassays in...

Preeclampsia is a major contributor to the maternal and neonatal mortality and morbidity.1,2 It is the 2nd largest cause of maternal mortality worldwide and affects 5% to 7% of pregnant women worldwide.3,4 The precise etiopathogenesis of preeclampsia remains to be a subject of extensive research, but it is believed that it is likely to be multifactorial. Nevertheless, it is accepted that it is ...

The etiology and pathogenesis of the pregnancy syndrome preeclampsia remain poorly understood. There is substantial evidence to suggest that the diverse manifestations of preeclampsia, including altered vascular reactivity, vasospasm, and discrete pathology in many organ systems, are derived from pathologic changes within the maternal vascular endothelium. With the theme of endothelial cell dys...

Preeclampsia which happens in 5-10% of pregnancies is associated with maternal and prenatal morbidity and mortality in all over the world. Preeclampsia leads to high rates of preterm birth, small for gestational age infant. The objective of the present study was to evaluate the effects of paternal cigarette smoking before and in conception on risk of preeclampsia in non smoker women without exp...

Preeclampsia is a dangerous disorder of pregnancy, defined as hypertension with proteinuria. Its nature remains elusive, and measures of prevention and treatment are limited. Observational studies have suggested that preeclampsia is associated with low intake of omega-3 long-chain polyunsaturated fatty acids (LCPUFA). In recent decades, researchers studied LCPUFA supplementation as a measure to...
