Eclampsia is a hypertensive disorder of pregnancy that is defined by the new onset of grand mal seizures on the basis of pre-eclampsia. Until now, the mechanisms underlying eclampsia were poorly understood. Brain edema is considered a leading cause of eclamptic seizures; aquaporins (AQP4 and AQP9), the glial water channel proteins mainly expressed in the nervous system, play an important role in brain edema. We studied AQP4 and AQP9 expression in the hippocampus of pre-eclamptic and eclamptic rats in order to explore the molecular mechanisms involved in brain edema...

BACKGROUND: Although hypertensive disorders of pregnancy are the leading cause of poor perinatal outcomes in Ethiopia, there is no study that shows the national prevalence. Therefore, the aim of this study was to estimate the national pooled prevalence of hypertensive disorders of pregnancy from studies conducted in different parts of the country. METHODS: Databases; MEDLINE, PubMed, HINARI, EMBASE, Google Scholar and African Journals Online were searched by using different search terms on HDP and Ethiopia...

Widespread consumption of high-fructose and high-fat diets relates to the global epidemic of hypertension. Hypertension may originate from early life by a combination of prenatal and postnatal nutritional insults. We examined whether maternal high-fructose diet increases vulnerability to post-weaning high-fructose or high-fat diets induced hypertension in adult offspring and determined the underlying mechanisms. Pregnant Sprague-Dawley rats received regular chow (ND) or chow supplemented with 60% fructose (HFR) during the entire pregnancy and lactation periods...

OBJECTIVE: To compare intrapartum and neonatal mortality in low-risk term women starting labour in midwife-led versus obstetrician-led care. STUDY DESIGN: We performed a propensity score matched study using data from our national perinatal register, completed with data from medical files. We studied women without major risk factors with singleton pregnancies who gave birth at term between 2005 and 2008 in the Amsterdam region of the Netherlands. Major risk factors comprised non-vertex position of the fetus, previous Caesarean birth, hypertension, (gestational) diabetes mellitus, post-term pregnancy (≥42 weeks), prolonged rupture of membranes (>24 hours), vaginal bleeding in the second half of pregnancy or induced labour...

Preeclampsia is a pregnancy-induced disorder characterized by hypertension and proteinuria after 20 weeks of gestation, affecting 5-7% of pregnancies worldwide. So far, the etiology of PE remains poorly understood. Abnormal decidualization is thought to contribute to the development of preeclampsia. SP1 belongs to the Sp/KLF super family and can recruit P300 to regulate transcription of several genes. SP1 is also very important for decidualization as it enhances the expression of tissue factor. In this study, we investigated the expression of SP1 and P300 in deciduae and their relationship with PE...

Preeclampsia is a pregnancy-specific disorder of new-onset hypertension and proteinuria after 20 weeks' gestation, often resulting in poor outcome. Previous studies demonstrated that apelin is an endogenous active peptide with visodilation and anti-oxidative stress capabilities. The present study investigated the effects of apelin in a rat model of preeclampsia induced by reduced uterine perfusion pressure (RUPP). Rats with RUPP displayed hypertension and poor pregnancy outcomes, such as decreased fetal and placental weight...

REVIEW
Chi Chiu Mok
The calcineurin inhibitors (CNIs) belong to a group of immunosuppressive agents that block T-cell activation through the suppression of the calcium/calcimodulin-dependent phosphatase calcineurin. Agents such as cyclosporine A (CSA) and tacrolimus (TAC) have long been used in patients with systemic lupus erythematosus (SLE). TAC is preferred to CSA in SLE because of the lower frequency of cosmetic, hypertensive and dyslipidemic adverse effects. Recent randomised controlled trials have demonstrated noninferiority of TAC to mycophenolate mofetil (MMF) or cyclophosphamide (CYC) for induction therapy of lupus nephritis...

BACKGROUND/AIMS: Studies have shown that a change in endothelin receptor expression in the artery is related to pregnancy-induced hypertension (PIH). However, the mechanism underlying this change remains unclear. METHODS: To test whether the distribution of endothelin receptor type-A (ETAR) and type-B (ETBR) plays an important role in PIH, a reduction of uterine perfusion pressure (RUPP) rat model was used to mimic some of the features of PIH; the resulting variable endothelin receptor expression was investigated in the media and intima of the aorta...

Preeclampsia is a pregnancy-specific disorder of maternal hypertension and reduced renal hemodynamics linked to reduced endothelial function. Placental ischemia is thought to be the culprit of this disease, as it causes the release of factors like tumor necrosis factor (TNF)-α that induce vascular endothelin-1 (ET-1) production. Interestingly, placental ischemia-induced hypertension in rats (reduced uterine perfusion pressure, RUPP model) is abolished by ETA receptor blockade, suggesting a critical role for ET-1...
