NCT ID: NCT03824119 Recruiting - Preeclampsia Clinical Trials

Postpartum NSAIDS and Maternal Hypertension

Start date: December 11, 2018
Phase: Phase 4
Study type: Interventional

Previous studies have suggested that NSAID use causes an increase in blood pressure. Further, blood pressure elevation has been noted in women with pregnancy related hypertensive disease during the postpartum period. NSAIDs remain part of standard postpartum care in women with hypertensive disease. The objective of this study is to determine whether postpartum standard care withholding NSAID use is associated with a clinically significant reduction in postpartum hypertension in women with pregnancy induced hypertension. The investigators hypothesize that women with pregnancy induced hypertensive disease will be half as likely to have blood pressure elevation of 150/100 mmHg in the first 24 hours postpartum. This study is an open label randomized trial of women with antepartum hypertension. Women will be randomized to receive standard postpartum care or standard postpartum care without NSAIDs. Blood pressure measurements and patient outcomes will be recorded. The study period will begin at the time of delivery and will end at the time of hospital discharge.

Fibroblast Growth Factor 23 and Hypertensive Disorder Complicating Pregnancy

Start date: May 1, 2019
Study type: Observational

Hypertensive disorder complicating pregnancy is a set of diseases of pregnancy coexisting with elevated blood pressure. The incidence of it is approximately 5-12%. Pregnancy-induced hypertension is a pregnancy-specific disorder, severely impairing both maternal and fetal health, and the major cause of maternal and perinatal mortality rate increased. But so far, the specific etiology is still unclear. Recently, fibroblast growth factor 23 (FGF23) has emerged as key endocrine regulators of the metabolism of vitamin D and calcium and phosphorus by combining FGFR-α- Klotho receptor complex. Current studies showed that α- Klotho involved the development of gestational hypertension via the production of endothelial nitric oxide, angiogenesis, and the formation of antioxidant enzymes. On the other hand, vitamin D deficiency during pregnancy has an adverse impact on maternal and fetal health, including gestational hypertension. Therefore, the relationship of the expression of FGF23 and the development of gestational hypertension has attracted the attention of relevant scholars. The aim of this study is to detect the difference of the expression of FGF23 between the hypertensive women and normal pregnant women.

NCT ID: NCT03815110 Active, not recruiting - Clinical trials for Gestational Hypertension

Preeclampsia Risk Assessment: Evaluation of Cut-offs to Improve Stratification

Start date: December 20, 2018
Study type: Observational

The purpose of this study is to 1. Identify a cut-off for the ratio of the serum proteins soluble FMS-like Tyrosine Kinase 1 (sFLT-1) and placental growth factor (PlGF) that identifies women will who develop preeclampsia with severe features within 2 weeks of testing (clinically positive) from those who do not develop preeclampsia with severe features within 2 weeks of testing (clinically negative) among preterm pregnant women with hypertensive disorders of pregnancy. And 2. To validate the cut-off the ratio of sFLT-1 and PlGF and to validate the performance of the automated assays used to find the cut-off. Test performance includes positive predictive value, negative predictive value, sensitivity, and specificity. Subjects will provide blood, urine, and saliva samples at the time of enrollment. Samples will be frozen for batch assessment of sFLT-1 and PlGF levels by automated assays. Clinicians, subjects, and researchers will be blinded to protein level assessment, therefore assay results will not affect clinical management.

NCT ID: NCT03814395 Recruiting - Obesity Clinical Trials

Peking University Birth Cohort in Tongzhou

Start date: June 28, 2018
Study type: Observational

The PKUBC-T is a prospective cohort study carried out in Tongzhou district of Beijing, China. The primary aim of this study is to investigate the short-term and long-term effects of pre-pregnant and prenatal exposure on maternal and child health. Data are collected regarding environmental, nutritional and lifestyle exposures as well as short-term and long-term health outcomes of mothers and their children from birth to 6 years old. Biological samples including blood and tissue samples are also collected from mothers and their children.

NCT ID: NCT03783169 Recruiting - Clinical trials for Hypertension in Pregnancy

SASH Study - Sonographic Assessment for Severe Hypertension in Pregnancy

Start date: December 11, 2018
Study type: Observational

• Adjunctive use of easily-obtainable maternal sonographic vascular measurements assessing volume status, cardiac output, and systemic vascular resistance by means of inferior vena cava collapsibility/caval index (ICV CI), end-point septal separation (EPSS) for determining left ventricular ejection fraction (LVEF), cardiac output determination (stroke volume x heart rate), stroke volume variation, & radial artery resistance index) augments standard vital sign assessment (pulse pressure and systolic / diastolic predominance) in clinical decision-making potentially leading to more appropriate pharmacologic and clinical therapies with faster resolution of severe hypertension among pregnant women and women in the postpartum period.

NCT ID: NCT03749746 Recruiting - Obesity Clinical Trials

Heart Health 4 New Moms: A Randomized Trial in the First Year After Preeclampsia

Start date: January 26, 2019
Phase: N/A
Study type: Interventional

Preeclampsia causes devastating maternal and neonatal morbidity and mortality with a high recurrence risk and a rapid, occult progression to cardiovascular disease after delivery. There is a critical need for effective interventions to reduce these risks. This is a pilot randomized controlled trial of a novel postpartum lifestyle intervention compared to women who take home blood pressure measurements and women with usual care who are overweight and obese in the first year after preeclampsia. The investigators hypothesize that the intervention will lead to improved weight loss and blood pressure in the first year postpartum, which has broad implications for future pregnancy and long-term cardiovascular health.

NCT ID: NCT03700034 Not yet recruiting - Clinical trials for Gestational Diabetes

mHealth Integrated Model of Hypertension, Diabetes and Antenatal Care in India and Nepal

Start date: November 2019
Phase: N/A
Study type: Interventional

The trial aims to enhance antenatal care (ANC) to address the changing disease burden affecting pregnant women in India and Nepal. The enhancement includes using a tablet-based electronic decision support system that prompts front line health workers to provide evidence-based routine ANC, enhances detection and management of pregnancy-induced hypertension and gestational diabetes, facilitates record-keeping and reporting, and links across levels of care providers.

NCT ID: NCT03693638 Completed - Clinical trials for Pregnancy Induced Hypertension

NCT ID: NCT03679117 Not yet recruiting - Clinical trials for Hypertension in Pregnancy

Prenatal Mindfulness & Hypertension Study

Start date: February 1, 2019
Phase: N/A
Study type: Interventional

Hypertensive disorders of pregnancy are one of the greatest causes of death to mothers and babies. These disorders affect 1 out of every 10 pregnancies, the rate is increasing in the United States, and rate of recurrence is as high as 50%. Treatments to prevent hypertensive disorders of pregnancy from happening in future pregnancies are limited. There are currently no effective interventions to prevent hypertension recurrence in pregnancy that do not involve medications. Mindfulness interventions hold great potential as a medication-free approach to prevent the recurrence of hypertension in pregnant women with histories of hypertensive disorders. However, traditional group-based mindfulness training interventions, requiring 2.5 hours of class attendance for 8 weeks plus a full-day retreat, are very difficult for pregnant women with medical conditions to attend. The goal of the current study is to determine if phone-delivered mindfulness training is an acceptable intervention among pregnant women with histories of hypertensive disorders of pregnancy. 20 pregnant women with histories of hypertensive disorders of pregnancy will be randomly picked to participate in an 8-week phone-delivered mindfulness training intervention (N=10) or usual care (N=10). All women will undergo blood pressure monitoring before and after the intervention. The investigators predict that phone-delivered mindfulness training will reduce risk for hypertension recurrence.

NCT ID: NCT03657823 Recruiting - Clinical trials for Congenital Heart Disease

Fetal Growth and Pregnancy Complications Among Women With Heart Disease

Start date: May 15, 2018
Study type: Observational [Patient Registry]

An increasing proportion of women with heart disease now go through pregnancy and childbirth. More knowledge about the risk of complications and adverse outcomes for the mother and the baby is needed to guide clinical care in this diverse patient group. The purpose of this study is to, in a cohort of pregnant women with heart disease; - determine fetal growth, and risk of fetal growth restriction and preterm birth - determine whether maternal blood biomarkers are associated with development of preeclampsia, the time of delivery and maternal and perinatal adverse outcomes - determine the risk of hypertensive pregnancy complications The expected outcome of the project is to increase the knowledge of optimal diagnosis and treatment of women with heart disease that go through pregnancy to be able to improve clinical care and the outcomes for mother and baby.
