OBJECTIVE: Preeclampsia is defined by the new onset of elevated blood pressure and protienuria after 20 weeks of gestation. Protienuria is one of the essential criteria for the clinical definition of preeclampsia. The authors investigated the predictive value of proteinuria in the outcome of pregnancies with preeclampsia. MATERIALS AND METHODS: In this retrospective cohort study, they entered all pregnant women who were admitted with diagnosis of preeclampsia in Yahyanejad Hospital from 1998 to 2008...

INTRODUCTION: As a result of concerns that 17α-hydroxyprogesterone caproate may increase risk of preeclampsia, our goal was to evaluate the association of 17α-hydroxyprogesterone caproate and preeclampsia in women with a prior preterm birth. METHODS: The records of women with a prior preterm birth who met criteria for 17α-hydroxyprogesterone caproate for the prevention of recurrent preterm birth from July 2011 through June 2013 were reviewed. Two groups were formed, a study group that received 17α-hydroxyprogesterone caproate and a control group that had the indication for 17α-hydroxyprogesterone caproate but never received the medication...

Preeclampsia is an important cause of maternal and perinatal morbidity and mortality. Previous studies have tested calcium supplementation and aspirin separately to reduce the incidence of preeclampsia but not the effects of combined supplementation. The objective of this study was to investigate the effectiveness of aspirin combined with calcium supplementation to prevent preeclampsia in women with chronic hypertension. A double-blind, placebo-controlled randomized clinical trial was carried out at the antenatal clinic of a large university hospital in São Paulo, SP, Brazil...

OBJECTIVE: To explore the predictive role of angiogenic factors for the prediction of early and late preeclampsia (PE) in the first trimester. METHODS: A nested case-control study, within a cohort of 5,759 pregnancies, including 28 cases of early, 84 of late PE (cut-off 34 weeks) and 84 controls. Maternal characteristics, mean blood pressure (MAP), uterine artery (UtA) Doppler (11-13 weeks), vascular endothelial growth factor, placental growth factor (PlGF), soluble Fms-like tyrosine kinase-1 (sFlt-1) and soluble endoglin (8-11 weeks) were measured/recorded...

OBJECTIVE: To find a risk factor for "uncomplicated" preeclampsia (PE) comparing blood biochemical parameters between women with uncomplicated PE and healthy pregnant women in each trimester of pregnancy. METHODS: A retrospective study was performed on 83 cases of uncomplicated PE, selected from 434 patients with PE, disregarding subjects with other complications relevant to hypertension during pregnancy. The study was limited to women with PE occurring in the third trimester, and records of blood biochemical parameters were evaluated...

BACKGROUND: Preeclampsia is a major cause of maternal and perinatal morbidity and mortality worldwide and especially in Latin America. High quality evidence indicates that calcium supplementation during pregnancy significantly reduces the incidence of preeclampsia and its consequences, including severe maternal morbidity and death. Few studies have assessed the implementation of this intervention in clinical practice. The study aimed to assess the proportion of pregnant women who received calcium supplements in Brazilian public antenatal care clinics...

BACKGROUND: Preeclampsia is a major cause of maternal and neonatal mortality and morbidity. The incidence of preeclampsia seems to be rising because of increased prevalence of predisposing disorders, such as essential hypertension, diabetes, and obesity, and there is increasing evidence to suggest widespread microcirculatory abnormalities before the onset of preeclampsia. We hypothesized that quantifying capillary rarefaction could be helpful in the clinical prediction of preeclampsia...

Preeclampsia remains to be a serious perinatal complication and early screening for this disease to identify the high risk population before the first symptoms develop constitutes a considerable clinical challenge. Modern methods of screening for preeclampsia and pregnancy-induced hypertension include patients history biochemical serum markers and foetal DNA and RNA in maternal serum. They aid the process of developing an optimal protocol to initiate treatment in early pregnancy and to reduce the rate of complications...

Preeclampsia (PE) affects around 2-5% of pregnant women. It is a major cause of maternal and perinatal morbidity and mortality. In an attempt to prevent preeclampsia, many strategies based on antenatal care, change in lifestyle, nutritional supplementation, and drugs have been studied. The aim of this paper is to review recent evidence about primary and secondary prevention of preeclampsia.

Preeclampsia remains a major cause of worldwide pregnancy related maternal and neonatal mortality and morbidity, it accounts for more than 50,000 maternal deaths each year. The World Health Organization estimates that at least one woman dies every 7 minutes from a complication of preeclampsia. It is the main cause of maternal death in Mexico and Latin America. Standarized assessment and surveillance of women with preeclampsia is associated with reduced maternal risk. Standarized sequence was established to search for practice guidelines from the clinical questions raised on diagnosis and treatment of preeclampsia-eclampsia...

OBJECTIVE: We sought to identify first-trimester maternal serum biomarkers for the prediction of late-onset preeclampsia (PE) using metabolomic analysis. STUDY DESIGN: In a case-control study, nuclear magnetic resonance-based metabolomic analysis was performed on first-trimester maternal serum between 11(+0)-13(+6) weeks of gestation. There were 30 cases of late-onset PE, i.e., requiring delivery ≥37 weeks, and 59 unaffected controls. The concentrations of 40 metabolites were compared between the 2 groups...

BACKGROUND: Preeclampsia is associated with both maternal and perinatal morbidity and mortality. Histidine-rich glycoprotein (HRG) is a protein interacting with angiogenesis, coagulation, and inflammatory responses, processes known to be altered in preeclamptic pregnancies. Significantly lower levels of HRG have been demonstrated as early as in the first trimester in women later developing preeclampsia compared with normal pregnancies. The aim of this study was to investigate whether the combination of HRG and uterine artery Doppler ultrasonography can be used as a predictor of preeclampsia...

Recent studies have shown that low serum 25-hydroxyvitamin D (25[OH]D) level is a risk factor for preeclampsia. The clinical significance of in vitro findings that vitamin D regulates vascular endothelial growth factor production is unclear. We sought to determine whether there is an association between midgestation serum 25(OH)D levels and angiogenic factor activity and to compare their predictive value for the development of severe preeclampsia. We conducted a nested case-control study of women with severe preeclampsia (n=41) versus women with uncomplicated term birth (n=123) who had second trimester genetic screening (15-20 weeks)...

Uric acid is a terminal metabolite of the degradation of nucleotides, which increases their blood levels in patients with preeclampsia-eclampsia, increasing its synthesis by damage and death of trophoblastic cells in proliferation and decreased urinary excretion due a lower glomerular filtration rate and increased absorption in the proximal tubule. Hyperuricemia (> 4.5 mg/dL) is the first biomarker of the clinical chemistry considered as an early evidence of disease (< or = 20 weeks gestation). Uric acid concentrations are not only a criterion for establishing the correct diagnosis and the differential with other hypertensive states, but an indication of termination of pregnancy, often by cesarean section...

BACKGROUND: Preeclampsia is one of the leading causes for maternal and fetal morbidity. Attempts to prevent preeclampsia have already been made using low-dose aspirin, low-molecular-weight heparin (LMWH), and calcium supplementation. Magnesium sulphate is used at the time of disease to prevent eclampsia. Here we investigated the effect of these agents on PP13 release from placental explants. METHODS: Placentas harvested after C-section of term or preterm control and preeclampsia cases or first trimester terminations were used to obtain explants...
