Hypertensive pregnancy disorders complicate 10% of all pregnancies and cover a spectrum of conditions, namely preeclampsia, eclampsia, and chronic and gestational hypertension. Preeclampsia is a pregnancy-specific disorder clinically characterized by hypertension and proteinuria that occurs after 20 weeks of gestation. It remains a leading cause of both fetal and maternal ...

Preeclampsia is the most common medical disorder of pregnancy. Early onset preeclampsia is defined as presentation of hypertension and proteinuria before 34 weeks of gestation. Alterations of endothelial cells and fibrin deposition in microvasculature lead to enhanced activation of the coagulation cascade and impaired fibrinolysis associated with multiple organ dysfunctions. ...

The exact pro-oxidant and antioxidant status in pregnancy--induced hypertension patients is still not clear. To add a new insight to the question, changes in the erythrocyte lipid peroxidation products (malondialdehyde; MDA), levels of glutathione (GSH), ascorbic acid and plasma vitamin E (non enzymatic antioxidant parameters) and activities of antioxidant enzymes ...

Obesity is an important risk factor for hypertensive disorders of pregnancy, but most cases of hypertensive disorders of pregnancy occur in women of normal weight. There may be predisposing factors to both hypertensive disorders of pregnancy and obesity. To test this hypothesis, the authors compared changes in body mass index ...

Hypertensive complications of pregnancy contribute to the burden of maternal morbidity and subsequently have an impact on neonatal morbidity and mortality. Although codes from the International Classification of Diseases should delineate the specific subtypes of pregnancy-related hypertension, how diagnoses are applied and how these codes are used in clinical settings ...

BACKGROUND: Maternal and fetal complications in pregnancies after renal transplantation have been highlighted in several reports, but information on their main predisposing factors is limited. The U.K. Transplant Pregnancy Registry was established in 1997 to obtain detailed information on pregnancies in female organ transplant recipients across the U.K. METHODS: For ...

Concentrations of soluble fms-like tyrosine kinase 1 (sFlt1) and soluble endoglin (sEng) increase in maternal blood with the approach of clinical preeclampsia. Although alterations in these circulating antiangiogenic factors herald the signs and symptoms of preeclampsia, in vitro studies suggest they may also play a role in regulating early placental ...

A low nephron number has been advocated to explain the association between intrauterine growth restriction (IUGR) and hypertension in later life. IUGR not only leads to a low birth weight but is also hypothesized to reprogram nephrogenesis, which results in a low nephron endowment. Several methods are used to estimate ...

Most epidemiological studies demonstrate that women suffering from migraine note significant improvement of their headaches during pregnancy. It is generally supposed, by both headache specialists and gynaecologists, that migraine does not involve any risk to the mother or the foetus. Specific investigations of the medical complications of pregnancy in migrainous ...

Antiphospholipid syndrome (APS) is frequently associated with complications during pregnancy. Miscarriage and maternal thrombosis are the most common problems, but prematurity, intrauterine growth retardation, pregnancy-induced hypertensive disorders, and pulmonary hypertension can complicate pregnancy as well. The correct treatment of these women requires an accurate preconceptual counseling and a close collaboration ...

CONTEXT: Soluble endoglin (sEng), a coreceptor for TGF with antiangiogenic properties, acts synergistically with soluble fms-like tyrosine kinase 1 (sFlt1) to induce symptoms of HELLP (hemolysis, elevated liver enzymes, low platelets) syndrome in animal models and to promote a preeclamptic phenotype. Pregnant women with preeclampsia show increased sEng concentrations in ...

Recent observation of maternal voice recognition provides evidence of rudimentary memory and learning in healthy term fetuses. However, such higher order auditory processing has not been examined in the presence of maternal hypertension, which is associated with reduced and/or impaired uteroplacental blood flow. In this study, voice processing was examined ...

Although unusual, pregnancy in chronic dialysis patients does occur. In fact, the percent of successful pregnancies in women on chronic dialysis may be increasing. But unfortunately, the rates for premature delivery, neonatal death, maternal hypertension, and preeclampsia in the chronic pregnant dialysis patient are high. Consequently, to have a successful ...

The purpose of this study was to investigate vascular reactivity in heterozygous and homozygous offspring with a genetic predisposition for hypertension after postnatal cross-fostering to mothers with the opposite genetic inheritance of the NOS3 knockout allele. Homozygous NOS3 knockout (C57BL/6J-NOS3(-/-KO)) and wild-type mice (NOS3(+/+WT)) were bred to obtain heterozygous litters ...

Kidney transplant improves reproductive function; planning for pregnancy is crucial. Prenatal management must address potential fetal complications: preterm delivery, intrauterine growth restriction, low birth weight; as well as maternal: hypertension, preeclampsia, gestational diabetes, acute rejection or graft loss. The latter depends upon timing after transplant, prepregnancy kidney function, and continuation ...

Preeclampsia is a hypertensive disorder unique to pregnancy and remains the leading cause of maternal and fetal morbidity and mortality. Despite active research, the etiology of this disease remains still an enigma. There is increasing evidence that a combination of several factors is responsible for the development of preeclampsia. In ...

Preeclampsia is associated with an increase of circulating levels of microparticles (MPs), but their role in vascular dysfunction during the course of preeclampsia is not understood. Inasmuch as preeclampsia is a gestational disease, we tested the effect of MPs from preeclamptic women (PrMPs) and MPs from normal pregnant women (CMPs) ...

BACKGROUND: Prepregnancy overweight is a risk factor for mild preeclampsia and mild transient hypertension of pregnancy. Its association with severe subtypes of these disorders has received less attention.
