BACKGROUND Preeclampsia is among the leading causes of maternal mortality and morbidity worldwide, occurs in 2-8% of all pregnancies, and is estimated to account for at least 9 % of maternal deaths in Africa. Studies from developed countries show that high pre pregnancy body mass index (BMI) increases the risk of preeclampsia. We examined the association between pre pregnancy BMI and the risk o...

To the Editor: Preeclampsia is a leading cause of maternal and fetal morbidity and mortality worldwide. It occurs in two phases: abnormal implantation of the placenta leads to impaired placental blood flow, which in turn induces the release of a critical placental substance into the maternal circulation (1 ). Clinical onset usually occurs in the third trimester of pregnancy, long after initiati...

Preeclampsia is one of the most feared pregnancy complications, with a risk of maternal and fetal death and with no ideal therapy readily available. The cause of this strictly pregnancyrelated disease is still unknown and is therefore a great challenge to all researchers in the field of pregnancy-related pathophysiology. Today, the dominating theory of the origin of preeclampsia is defective in...

Preeclampsia is a disorder of pregnancy diagnosed by gestational hypertension and proteinuria. Epidemiological evidence suggests that women who experience preeclampsia are at a greater risk of hypertension and heart disease later in life compared with women who had normal pregnancies. Our objective was to determine whether endothelial function is impaired in postpartum women with a history of p...

In preeclampsia, maternal microvascular function is disrupted and angiogenesis is dysfunctional. Insulin resistance that occurs in some pregnancies also pathologically affects microvascular function. We wished to examine the relationship of angiogenic mediators and insulin resistance on microvascular health in pregnancy. We performed a nested, case-control study of 16 women who developed preecl...

OBJECTIVE Relaxin, a potent pregnancy-related hormone, has been proposed to be a major mediator of renal physiology in normal pregnancy. We wished to test relaxin levels in pregnancy and preeclampsia. METHODS We performed precise physiologic measurements of kidney function in 38 normal peripartum women and 58 women with preeclampsia. We measured serum relaxin levels prior to delivery and over...

Background and purpose: Preeclampsia is a hypertensive disorder in pregnancy and is known as a specific syndrom of pregnancy. Several studies have been done to asses the indicators of preeclampsia for early detection of the disease. Uric acid is considered by some investigators as one of the most sensetive indicators in preeclampsia. In contrast some researchers have found it not useful in pr...

Digital Comprehensive Summaries of Uppsala Dissertations from the Faculty of Medicine 1364. 98 pp. Uppsala: Acta Universitatis Upsaliensis. ISBN 978-91-513-0057-3. Preeclampsia and eclampsia are among the most common causes of maternal and fetal mortality and morbidity worldwide. There are no reliable means to predict eclampsia o...

با وجود شواهد روزافزونی که بیانگر نقش احتمالی ANP در هموستاز طبیعی مایعات بدن است، اما هنوز اهمیت نقش این پیتید در سلامت و بیماری بدرستی مشخص نیست. بر اثر ازدیاد فشار دهلیزی و تعداد انقباضات آن، ANP از میوسیت های دهلیزی ترشح می شود. تزریق مقادیر زیادی از ANP صناعی به انسان و حیوان سبب کاهش فشار سیستمیک دهلیزی و افزایش دفع سدیم و برقراری دیورز می گردد. مطالعات اخیر بر روی تأثیر تزریق ANP صناعی ...
