Filter by:Postpartum hemorrhage is an important cause of maternal morbidity and mortality. In patients with severe preeclampsia there is an increased risk of postpartum hemorrhage but the hemodynamic changes associated with this pathology make the management of any kind of bleeding particularly troublesome. There are many pharmacological options, being oxytocin the first line of treatment. However there is no evidence about the safety and efficacy of carbetocin, an oxytocin agonist. The investigators aimed to compare oxytocin with carbetocin for the routine prevention of postpartum hemorrhage in patients with severe preeclampsia.
Hypertensive disorders of pregnancy are one of the most frequent complications of pregnancy, being a serious health problem around the world. Previous studies have suggested that there is an association between a short period of exposure to paternal sperm of a new sexual partner and the development of an immunological reaction that could trigger a hypertensive disorder of pregnancy. For this reason we want to study the relationship between the primipaternity concept (exposure to male antigens present in semen over a short period of time previous to the pregnancy) and the development of preeclampsia in adolescents.
Could possible markers in serum obtained in the first trimester predict the human-pregnancy specific disorder pre-eclampsia?
Introduction: Hypertensive emergency in pregnant women with pre-eclampsia should be treated for preventing stroke and placental abruption. However, the benefit of antihypertensive medication maintenance remains unclear, mainly due to the potential risk of fetal growth restriction.
To determine the efficacy of high dose folic acid supplementation for prevention of preeclampsia in women with at least one risk factor: pre-existing hypertension, pre-pregnancy diabetes (type 1 or 2), twin pregnancy, preeclampsia in a previous pregnancy, or body mass index ≥35. It was hypothesized that high dose (4.0 mg per day) supplementation starting in early pregnancy and continued throughout the entire pregnancy will lower the incidence of preeclampsia in pregnant women at high risk of developing preeclampsia.
Placental insufficiency is the source of preeclampsia (PE) and intrauterine growth retardation (IUGR). Current data demonstrate a significant beneficial effect of prophylactic use of aspirin on the recurrence of placental insufficiency and its complications, mainly preeclampsia, when started early in pregnancy. However, there is a significant heterogeneity in medical practice in Canada and around the world in terms of the dose of aspirin used. The objectives of this study are: 1) Evaluate whether a dose of 160 mg of aspirin is associated with greater improvement in placental function assessed by biochemistry (sFlt-1 and endoglin) and ultrasound (uterine artery Doppler) than a dose of 80 mg in women with a history of PE, 2) Assess whether the change is dependent on platelet aggregation measured by a test used in several Canadian centers (PFA-100).
Preeclampsia is associated with significant maternal and fetal morbidity and mortality. Early identification and subsequent management of patients at risk of developing preeclampsia presents an ongoing challenge in prenatal care. Some at risk pregnancies may be identified from: - serum screening abnormalities in the first or second trimester - placental shape and texture at the 18-20 anatomical ultrasound - uterine artery blood flow. Early identification and effective treatment of patients would permit the safe completion of the pregnancy for the mother and infant. Recent advances in non-invasive cardiovascular monitoring have enabled the study of maternal hemodynamics in normal and at-risk pregnancies. This study hopes to identify the earliest significant changes in maternal hemodynamics which may allow targeted therapeutic interventions in patients at high risk of developing preeclampsia. The hypothesis of this study is that systemic vascular resistance rises during the pre-clinical phase of preeclampsia and this can be captured using non invasive bioreactance technology. Treatment of the abnormally high vascular tone may decrease the severity and postpone the onset of clinical disease.
To assess the role of uterine artery and maternal serum PlGf and sflt-1 and their combination in screening for pre-eclampsia and small -for-gestational age (SGA) fetuses at 12-14 weeks of gestation
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 is a form of hypertension that is unique to human pregnancy. The incidence of the disease ranges between 2 and 7 percent in healthy nulliparous women. The etiology of preeclampsia is unknown. Women with preeclampsia may exhibit a symptom complex ranging from minimal BP elevation to derangements of multiple organ systems. The renal, hematologic, and hepatic systems are most likely to be involved. More than 100 clinical, biophysical, and biochemical tests have been recommended to predict or identify the patient at risk for the future development of the disease. The results of the pooled data for the various tests and the lack of agreement between serial tests suggest that none of these clinical tests is sufficiently reliable for use as a screening test in clinical practice. As a result there is obviously a great need to develop a novel technology for the early detection of this pregnancy complication before its clinical manifestations appear. An early detection can help in early treatment to prevent or at least minimize the sequel of this disease. The aim of this project is the early detection of "Preeclampsia" and other pregnancy complications using volatile biomarkers appearing in exhaled breath and/or blood samples, using a simple and inexpensive toll termed NA-NOSE. Phase-I: The primary phase of this project is the comparison between volatile biomarkers' patterns of pregnant women suffering from "Preeclampsia", pregnant women that are considered to have "Normal Pregnancy", and healthy "Non-Pregnant" women. Phase-II: The secondary phase of this project is the ability to predict "Preeclampsia", as compared, head-to-head, with other potential predictors used in the current clinical practice.
