Active clinical trials for "Pre-Eclampsia"

There are no studies evaluating the effect of aging on hemostasis of preeclamptic patients. Additionally, although there are some studies that establish normal reference values for TEG profiles in healthy term pregnant patients, conflicting results have been found in preeclampsia. Reference values are important to establish baseline parameters in cases of pre-eclampsia complicated by postpartum hemorrhage. The investigators will evaluate reference values for TEG in postdelivery preeclamptic patients and the difference between vaginal delivery and cesarean section.

Preeclampsia, one of the hypertensive disorders of pregnancy, remains a leading cause of maternal death worldwide, with the majority of deaths occurring in developing countries. Preeclampsia is a multi-organ syndrome of pregnancy that manifests after 20 weeks' gestation with new-onset hypertension alongside maternal end-organ dysfunction and/or fetal growth restriction. Importantly, preeclampsia poses serious health risks for the baby, implicated in 12% of cases of fetal growth restriction, and is a known antecedent in up to 19% of preterm births. There is currently no effective treatment for preeclampsia except delivery of the baby, and as such, it remains a significant burden of disease for both mothers and their babies worldwide. Screening for women at risk of preeclampsia is an important part of antenatal care. Once women are identified as high risk, they can be targeted for more intensive antenatal surveillance and prophylactic interventions. Most current strategies for risk assessment are based on obstetric and medical history and clinical examination. However, there is surprisingly little reliable evidence on the actual risk associated with individual factors and how they might interact. Risk factors with a particularly high association with preeclampsia (more than one in ten risks) include maternal diabetes, chronic hypertension, and renal disease. Thrombophilia and autoimmune disease have a strong association with severe early-onset preeclampsia. Obstetric factors associated with high risk are multiple pregnancies, history of preeclampsia in a previous pregnancy especially if severe or early onset, and a current hydropic pregnancy. Other factors linked with preeclampsia but associated with a somewhat lower risk include first pregnancies, age less than 20 or more than 35 years, a family history of preeclampsia, and obesity. Proton pump inhibitors such as esomeprazole have long-term safety data about the treatment of gastric reflux in pregnancy. In vitro studies show proton pump inhibitors decrease soluble fems like tyrosine kinase -1 (sFlt-1) and soluble endoglin and improve markers of endothelial dysfunction . while esomeprazole reduces blood pressure in a preeclampsia transgenic mouse model that overexpresses sFlt-1.

There are data showing that a majority of pregnant women may not be accurately identified as high risk through screening and therefore, not receiving prophylactic low dose aspirin as recommended. This leads to missing many patients who would benefit from aspirin administration. Aspirin is an effective, affordable and safe intervention and its universal use in pregnancy has been proposed as the answer to help mitigate risk of significant morbidity from preeclampsia. However, adherence to aspirin in women at low risk compared to those deemed at high risk of preeclampsia has never been studied. One of the arguments against universal aspirin administration is the concern that universal receipt would change the compliance in those at high risk although there are no data to support this concern. To address the lack of data on differences in adherence, our goal in this proposal is to assess whether there is a difference in adherence to low dose aspirin (81 mg) in women at high risk of preeclampsia as indicated by USPSTF risk algorithm when compared to those women randomized to universal use.

This study intends to adopt the method of multi-center prospective randomized controlled study. The aim of this study is to obtain localized excision values through a preeclampsia screening model established in early pregnancy, and to evaluate the efficacy of low-dose aspirin intervention for preeclampsia prevention in pregnant women at high risk of screening.

This study is designed to comprehensively investigate the anti-inflammatory role of vitamin D in reproductive aged women, and its association with preeclampsia and depression. Findings will have substantial impact providing new information implicated in the development of preeclampsia (a condition that may include hypertension, tissue swelling caused by excessive fluid, and kidney stress) and postpartum depression (after birth). Additionally, the study is designed to understand how early mental health screening and evaluation can help pregnant women reduce their risk of developing postpartum depression. Testing the acceptability and effectiveness of this mental health screening, education and referral program at Cedars-Sinai Medical Center will provide valuable patient centered qualitative and quantitative data that can be used in future services planning. The study will enroll up to 200 pregnant women (in third trimester of pregnancy) in total.

Primary Endpoint: Quantify the hemodynamic changes in preeclampsia using the non-invasive Nexfin device. Secondary Endpoint: Determine if measurable hemodynamic changes are statistically correlated with B-type natriuretic peptide (BNP) levels.

To evaluate the feasibility of screening for preeclampsia and fetal growth restriction between 11-13+6 weeks' gestation utilizing the combination of uterine artery doppler, maternal blood pressure, maternal characteristics, placental volume, and maternal serum factors, including PAPPA-A, PLGF, AFP and free Beta HCG. This is a non interventional study.

This study evaluates the effectiveness of maternal supplementation with Docosahexaenoic acid (DHA) early in pregnancy to reduce the incidence of deep placentation disorders: preterm birth, preterm labor, preterm premature rupture of membranes, preeclampsia and fetal growth restriction. Half of the participants in early pregnancy will receive DHA 600 mg per day, while the other half will receive placebo. Investigators will study also the ability of DHA supplementation, early in pregnancy, to enhance invasion and transformation of spiral arteries by trophoblast, as deep placentation indicators.

the purpose of this study is to determine whether calcium supplementation is effective to prevent preeclampsia in Sichuang Province of china and which dose is more suitable

Background: Obesity in pregnancy is increasing and is a risk factor for metabolic pathology such as preeclampsia. Leptin is an adipokine which has a direct relationship to obesity. Aim: to measure leptin in lean, obese and diabetic pregnant women at three months intervals throughout their pregnancies. Methods: Pregnant women were recruited in the 1st trimester of pregnancy, and three groups were formed: a) with pregestational Body Mass Index (BMI) less than 25 kg/m2, b) BMI higher than 25 kg/m2 and c) with Gestational Diabetes Mellitus (GDM). Serum levels of leptin were measured with radioimmunoassay (RIA) technique.
