Filter by:Background: - Preeclampsia is a combination of high blood pressure and other potentially life-threatening symptoms. Preeclampsia occurs in up to 10% of pregnancies and is a main cause of maternal and fetal death worldwide. Treatment is often difficult, and so far there is no specific and effective therapy. Researchers have been studying the body systems that regulate blood pressure. They have also studied drugs that can control certain blood chemicals that constrict blood vessels and increase blood pressure. - DIGIBIND, a drug that lowers blood pressure, has been used to treat pre-eclampsia. Marinobufagenin (MBG), a chemical in the blood that constricts blood vessels, has been shown to be involved in pre-eclampsia. But researchers are still not certain whether DIGIBIND can be used to specifically target MBG. Researchers want to find out whether DIGIBIND acts against MBG specifically. This information may help them to develop better drugs to block MBG and lower blood pressure in women with preeclampsia. Objectives: - To study whether the blood pressure treatment drug DIGIBIND specifically acts on marinobufagenin levels in the blood of pregnant women. Eligibility: - Women between 18 and 50 years of age who are 34 to 39 weeks pregnant and have preeclampsia. Design: - Participants will be screened with a physical examination, medical history, and blood and urine tests. - Before delivery, participants will provide blood samples for testing and evaluation. - Following delivery, participants will provide additional blood samples and samples of the placenta for testing and evaluation. - No additional treatment, apart from the standard of care, will be provided as part of this protocol.
Preeclampsia and other high blood pressure disorders of pregnancy are a significant cause of both maternal and fetal complications of pregnancy. To date, there is no known "cure" for preeclampsia, but studies have shown that exercise may lower the risk of preeclampsia and high blood pressure disorders in pregnancy. Resistance training also lowers blood pressure, and may be easier to perform in a pregnant population, leading to higher compliance. The investigators propose to perform a novel prospective study of a resistance training regimen on blood pressure in pregnant patients at high risk for developing preeclampsia or high blood pressure.
The purpose of this study is to investigate the benefit of several micro nutrients of antioxidants (using milk) in a cohort of women with low antioxidant status and the changes in cell-free mRNA.
The purpose of this study is to determine whether the Fetal Medicine Foundation algorithm for individual risk calculation for preeclampsia (PE) and pregnancy induced hypertension (PIH) is suitable to identify women in high risk of developing these diseases in a Norwegian population.
How best to manage preeclampsia remote from term is controversial because of conflicting maternal and neonatal risks. Gestational age is the most important determinant of neonatal outcome. There are two basic approaches when delivery is not clear indicated by assessment of maternal and fetal well-being. The interventionist care when the delivery is planned within 48 hours and the expectant care which refers to pregnancy prolongation during which time women and fetuses are carefully monitored for indications for delivery. The purpose of this study is to evaluate maternal and perinatal outcomes with expectant vs interventionist or aggressive management of severe preeclampsia at 28 to 33 weeks of gestation.
Participants counseled with the preeclampsia educational tool will have a better understanding of preeclampsia than those not counseled using the tool.
The risk of venous thromboembolism increases in pregnancy. Thrombophilia whether genetic or acquired, is a hypercoagulable disorder that may increase the risk of venous thromboembolic events. Clinically, these events are presented as maternal deep vein thrombosis and pulmonary emboli. Thrombophilias are also associated with adverse fetal outcomes including intrauterine growth restriction, intrauterine fetal death, severe preeclampsia, placental abruption and recurrent abortions. Pregnant women who experienced one or more of the above complications are advised to be examined for the presence of the genetic or the acquired form of thrombophilia. Low molecular weight heparin prophylaxis, an anticoagulant, is advised for pregnant women with a history of thromboembolism, and many experts recommend prophylaxis for pregnant patients with a known thrombophilia and history of adverse pregnancy outcomes associated with these hypercoagulable states. Physiologic changes in normal pregnancy, including weight gain, increased renal clearance and volume of distribution, may decrease the availability of low molecular weight heparin (Enoxaparin or Dalteparin), or produce a less predictable response in pregnant women compared with nonpregnant women. There are no clear recommendations for use of prophylactic low molecular weight heparin in pregnancy. Clinicians tend to use doses suggested for nonpregnant patients. Regarding pregnant patients taking enoxaparin or dalteparin, the American College of Obstetricians and Gynecologists states that "because of the lack of data regarding adequate dosing during pregnancy, anti-factor Xa levels may be monitored". Two recently published studies demonstrated that plasma anti-factor Xa levels during pregnancy were lower than expected, indicating that many pregnant patients may receive a subprophylactic dosing. Our objective is to check pregnancy outcome among thrombophilic women treated with an adjusted enoxaparin thromboprophylaxis dosage according to anti-factor Xa plasma levels compared to women with fixed dosage.
This study is a multi-site, retrospective chart review to determine the effect of Neevo® or Neevo®DHA (with higher folate and B12) versus standard prenatal vitamins on hemoglobin (Hgb) levels in pregnant women throughout the course of pregnancy. Neevo® is a prescription medical food indicated for the dietary management of women under a doctor's care who face high risk pregnancies, older overactive bladder (OB) patients and patients unable to fully metabolize folic acid. Data will be collected from existing patient charts of subjects administered Neevo® or Neevo®DHA daily compared to subjects administered a prenatal vitamin daily.
The study is focused on the investigation of possible associations between plasma/serum levels of agouti related peptide (AgRP) and its genetic background in healthy women with physiological pregnancy (non-preeclamptic) and women with preeclampsia, in the postpartum period, and in their offspring.
This pilot study will document the efficacy and acceptability of administration of magnesium sulfate with the Springfusor pump for patients and staff at two sites where treatment or preeclampsia with magnesium sulfate is limited or not available. Currently, both sites refer patients to tertiary care facilities for further treatment.
