OBJECTIVE: Preeclampsia (PE) is a pregnancy-induced hypertension with proteinuria that typically develops after 20 weeks of gestation. A reduction in uterine blood flow causes placental ischemia and placental release of anti-angiogenic factors such as soluble fms-like tyrosine kinase (sFlt-1) followed by PE. Although the reduced uterine perfusion pressure (RUPP) model is widely used in rats, investigating the genetics of PE has been problematic because it has been difficult to make a useful RUPP model in mice...

OBJECTIVE: Severe forms of hypertensive disorders of pregnancy, like early-onset preeclampsia (PE), are often linked with abnormal placentation. Genetic factors contributed by the father may be important for placental development, and previous studies support the existence of a paternal component for PE and fetal growth restriction. Thus, the present study was conducted to evaluate the influence of arterial hypertension as a paternal factor on placental development and fetal growth in normal female rats...

BACKGROUND: Preeclampsia (PE), an endothelial disease that affects kidney function during pregnancy, is correlated to an increased future risk of cardiovascular and chronic kidney disease. The Kidney Disease Improving Global Outcomes (KDIGO) 2012 guideline emphasizes the combined role of glomerular filtration rate (GFR) and albuminuria in determining the frequency of monitoring of kidney function. OBJECTIVES: In this study we evaluated the prevalence of CKD in women with a history of PE...

The most recent Cochrane reviews on oral antihypertensive drugs in pregnancy conclude that no substantial benefits for the mother or fetus are demonstrated so far. Whether this applies for a high-risk and diabetic pregnancy is doubtful. The aim of this short review is an introduction to the field of ambulatory blood pressure measurements in pregnancy and in particular in women with type 1 diabetes. Diabetic pregnancy is complicated with a 50% risk of hypertension/preeclampsia. In the nonpregnant, diabetic women minute increases in blood pressure as well as in albuminuria are forerunners for incipient and overt nephropathy...

Preeclampsia (PE) is a pregnancy-induced hypertension with proteinuria that typically develops after 20 weeks of gestation. A reduction in uterine blood flow causes placental ischemia and placental release of anti-angiogenic factors such as sFlt-1 followed by PE. Although the reduced uterine perfusion pressure (RUPP) model is widely used in rats, investigating the role of genes on PE using genetically engineered animals has been problematic because it has been difficult to make a useful RUPP model in mice. To establish a RUPP model of PE in mice, we bilaterally ligated ovarian vessels distal to ovarian branches, uterine vessels, or both in ICR-strain mice at 14...

Preeclampsia is associated with an increased inflammatory response. Immune suppression might be an effective treatment. The aim of this study was to examine whether Cyclosporin A (CsA), an immunosuppressant, improves clinical characteristics of preeclampsia and suppresses inflammation in a lipopolysaccharide (LPS) induced preeclampsia rat model. Pregnant rats were randomly divided into 4 groups: group 1 (PE) rats each received LPS via tail vein on gestational day (GD) 14; group 2 (PE+CsA5) rats were pretreated with LPS (1...

OBJECTIVE: Preeclampsia is characterized by disturbed placentation, hypertension, proteinuria, and suppression of plasma renin, angiotensin II, and aldosterone. Regulated activity of tissue serine proteases, prostasin, and matriptase is necessary for normal placental development in mice. Prostasin activates the renal epithelial sodium channel. We hypothesized that preeclampsia is associated with low prostasin expression in placenta and spillover of prostasin into urine across the defect glomerular barrier...

The CD40 ligand (CD40L) is expressed by T cells and has a critical role in immune system regulation. Interventions targeting CD40L interactions following embryo implantation represent an approach to preventing preeclampsia (PE). To better understand the role of CD40L in PE, we developed a PE mouse model in which we examined how CD40L-induced immune activation affects embryo implantation. Blastocysts were incubated with CD40L-expressing adenovirus and then were transferred into the uterine horns of pseudopregnant ICR mice...

BACKGROUND: During pregnancy, Low serum 25-hydroxyvitamin-D [25(OH)D] concentration is even more critical. This deficiency leads to higher incidences of preeclampsia, gestational diabetes, preterm birth, bacterial vaginosis, and also affects the health of the infants. The aim of this study was to evaluate the relationships between serum levels of 25-hydroxyvitamin D (25[OH]D) and gestational diabetes mellitus (GDM) and differences in high-risk pregnant women and women without risk factors for GDM...

OBJECTIVES: Abnormal urinary protein loss is a marker associated with a diverse range of renal diseases including preeclampsia. Current measures of urine protein used in the diagnostic criteria for the diagnosis of preeclampsia includes urine protein:creatinine ratio and 24-h urine protein. However very little is known about the value of urine albumin:creatinine ratio (uACR) in pregnancy. In this study we examined the prognostic value of microalbuminuria detected antepartum to predict adverse pregnancy outcomes...

In pregnancy, placenta can be exposed to glucocorticoids (GCs) via several ways, which may disturb placentation and adversely affect pregnancy. Preeclampsia (PE) is thought to be attributed, in part, to impaired trophoblast development. The purpose of the present study was to confirm that GC exposure in early placentation could lead to PE in rats, with the mechanisms involving dysregulated trophoblast development. In the study, pregnant rats were administered with 2.5mg/kg Dex subcutaneously once per day from gestational day 7 to 13...

UNLABELLED: In women with a history of preeclampsia, low plasma volume (≤1373 mL/m(2)) is associated with recurrent preeclampsia and chronic hypertension. Interventions that improve volume reserve may reduce these risks in formerly preeclamptic women. In this study, we examined the effects of aerobic exercise training on venous reserves in 24 normotensive formerly preeclamptic women and 20 controls. Before and after 12-week aerobic exercise training, we measured plasma volume with albumin indicator dilution technique and venous compliance with venous occlusion plethysmography...

BACKGROUND: The influence of common disturbances seen in preeclampsia, such as changes in strong ions and weak acids (particularly albumin) on acid-base status, has not been fully elucidated. The aims of this study were to provide a comprehensive acid-base analysis in severe preeclampsia and to identify potential new biological predictors of disease severity. METHODS: Fifty women with severe preeclampsia, 25 healthy non-pregnant- and 46 healthy pregnant controls (26-40 weeks' gestation), were enrolled in this prospective case-control study...

OBJECTIVE: Patients with preeclampsia (PE) have endothelial dysfunction and an increased future risk of cardiovascular (CV) mortality. The number of circulating endothelial cells (CECs) is markedly increased in conditions associated with a high degree of endothelial cell activation/injury including PE. We hypothesized that the number of CECs continues to be increased in women with a history of PE, reflecting ongoing endothelial cell activation/injury. STUDY DESIGN: CECs, flow-mediated vasodilation, levels of adhesion molecules and soluble vascular endothelial growth factor receptor-1 (sVEGFR1), and urine albumin/creatinine ratio were determined in 21 healthy women with ongoing normal pregnancy, 24 healthy currently nonpregnant women with a history of normal pregnancy, a total of 17 women with currently active mild (n = 11) or severe (n = 6) PE without hemolysis, elevated liver enzymes, and low platelet count (HELLP) syndrome, and 16 currently nonpregnant women with a history of mild (n = 10) or severe (n = 6) PE...

UNLABELLED: Preeclampsia remains the highest causes of maternal mortality in Indonesia. This disease is known as "the disease of theories" since the etiology of this disease still obscure, but it is clearly accepted that this disease is correlated with placenta. The incidence of this disease increased in dr. Soetomo General Hospital during economic crisis in Indonesia, as nutritional problem occurred, but correlation between nutrition to preeclampsia still unclear. This study was conducted to find out the influence of hypoalbuminemia caused by alteration of amino acids and changes of GRP78 and placental VEGF in preeclampsia...

OBJECTIVE: Women with preeclampsia (PE) display low renin-angiotensin-aldosterone system (RAAS) activity and a high anti-angiogenic state, the latter characterized by high levels of soluble Fms-like tyrosine kinase-1(sFlt-1) and reduced levels of placental growth factor (PlGF). In the present study, we hypothesized that the RAAS suppression in PE is the consequence of the disturbed angiogenic balance. DESIGN AND METHOD: In a group of pregnant women with hypertensive disease of pregnancy and a group of healthy pregnant women, matched for gestational age (GA) we measured mean arterial blood pressure (MAP), urinary protein-to-creatinine ratio (PCR), and the plasma levels of sFlt-1, PlGF, albumin, creatinine, endothelin-1 (ET-1), renin (concentration and activity, PRC and PRA), angiotensinogen, and aldosterone...

Preeclampsia is one of the most important and complexed disorders for women's health. Searching for novel proteins as biomarkers to reveal pathogenesis, proteomic approaches using 2DE has become a valuable tool to understanding of preeclampsia. To analyze the proteomic profiling of preclamptic placenta compared to that of normal pregnancy for better understanding of pathogenesis in preeclampsia, placentas from each group were handled by use of proteomics approach using 2DE combined with MALDI-TOF-MS. The 20 spots of showing differences were analysed and identified...
