Pre-Eclampsia Clinical Trials

The purpose of this study is to validate the accuracy of the CONNEQT Pulse blood pressure monitoring system for the measurement of blood pressure as compared to a gold standard, auscultatory sphygmomanometer in a pregnant population. Read Less

The objective of this research project is to conduct a single-site pilot trial within our institution's clinical remote blood pressures (BP) management program to assess the feasibility and effect of tight blood pressure control versus usual care in the immediate postpartum period after a hypertensive disorder of pregnancy (HDP). The investigators' central hypothesis is that tight blood pressure control will be feasible and acceptable to postpartum individuals and will result in lower BP at six months postpartum and a reduction in postpartum hospital readmissions. Subjects will undergo 3 study visits (1 in-person and 2 remote) involving BP measurements, blood draws, and/or questionnaires. Up to 60 adult subjects will be enrolled at Magee-Women's Hospital.

The purpose of this study is to conduct a pilot randomized controlled trial of a food is medicine community health worker intervention called the Women's Health Delaware Food Farmacy compared to the usual standard of care among pregnant ChristianaCare patients at risk for adverse clinical outcomes. The pilot study has three specific aims: Aim 1: To assess the feasibility of the Women's Health Delaware Food Farmacy and refine the program as needed Aim 2: To determine the prevalence of and change in social needs Aim 3: To evaluate the effectiveness of the Women's Health Delaware Food Farmacy on maternal and child health, healthcare utilization, and clinical event outcomes as well as patient-reported outcomes compared to the usual standard of care Read Less

NatPro is a two-arm, parallel-group, multi-center, randomized trial in which women undergoing frozen embryo transfer (FET) will be randomized to receive either a modified natural cycle (corpus luteum present) or a programmed cycle (corpus luteum absent). Read Less

The investigators will collect omental tissue (research surgical excision) and placental tissue (standard of care clinical delivery) from both preeclamptic and non-preeclamptic women during their c-section and use these samples to study the blood vessels, specifically the expression/activation of the AT2R.

This is a single site, single-blinded parallel randomized control trial that investigates a multi-level intervention to improve postpartum blood pressure in women with hypertensive disorder pregnancy. The investigators will recruit women diagnosed with a hypertensive disorder of pregnancy, identified between 3rd trimester and 2 weeks post-delivery. The investigators will randomize participants to receive usual care home blood pressure monitoring for 6 weeks versus an intervention of usual care + blood pressure and weight monitoring + a doula trained in heart health. This trial will be conducted in partnership with a local community-based organization, Healthy Start Inc. Read Less

Endothelial dysfunction and defective placental vascularization are hypothesized to be significant causes of preeclampsia. In preeclampsia, due to vascular endothelial dysfunction, vasoconstriction and platelet activation can result in severe features which alter pregnancy outcomes. However, studies have shown that acetylsalicylic acid (Aspirin) can decrease endothelial dysfunction leading to decreased platelet aggregation which reduces adverse outcomes. The objective of our study is to determine if Aspirin has a dose-dependent response for modifying biomarkers reflective of maternal endothelial dysfunction when indicated for preeclampsia prevention in a cohort of women identified at risk for developing preeclampsia. Pregnant women who are at risk for preeclampsia will be randomized to receive either 81mg Aspirin or 162mg Aspirin daily starting from 11-16 weeks of gestation until 36 weeks of gestation. A third, control group of women at low risk for preeclampsia will not receive aspirin. All women will be assessed with uterine artery Doppler studies and mean arterial blood pressures at three time points during pregnancy. Blood, urine, and cord blood samples will also be collected.

In 2017, the American College of Cardiology and the American Heart Association changed the diagnostic criteria for hypertension in non-pregnant adults. The parameters for the diagnosis of stage 1 hypertension were revised from a systolic blood pressure (BP) of 140 to 130 mm Hg and a diastolic BP of 90 to 80 mm Hg. Based on new criteria, stage 1 hypertension is associated with a 2-3 fold increased risk of preeclampsia. There are no data regarding prevention of preeclampsia in women with stage 1 hypertension. Low-dose aspirin has been used during pregnancy to prevent preeclampsia for women at high-risk for preeclampsia. Although the precise mechanism remains uncertain, it is possible that low-dose aspirin improves placental perfusion, which results in a decreased rate of preeclampsia. A study that examines the effect of low-dose aspirin on placenta vasculature and tissue elastography by using novel ultrasound tools would be useful. The 2017 Aspirin for Evidence-Based Preeclampsia Prevention trial compared 150 mg aspirin with placebo in women at high-risk of preeclampsia based on a first-trimester screening. They found a significant decrease in the rate of preterm preeclampsia (4.3% vs. 1.6%; P <0.01). Since this study used the screening algorithm including first-trimester serum markers and uterine artery Doppler, the generalizability in the U.S. women with stage 1 hypertension is limited. Our pilot study will examine 1) the effect of low-dose aspirin 81 mg in women with stage 1 hypertension on placental vasculature and shear-wave elastography; 2) the rate of preterm preeclampsia in women with stage 1 hypertension in a control group and in pregnancies treated with low-dose aspirin 81 mg; 3) feasibility of conducting a larger multicenter randomized controlled trial on this subject.
