Filter by:Preeclampsia (PE) is a hypertensive pregnancy-related disorder that endangers maternal and fetal outcomes and accounts for 9-10% of maternal mortalities with its early-onset phenotype is the most dangerous, but its etiology is still not fully elucidated. Midkine (MDK) is a multifunctional protein that plays a unique role in the development of hypertension (HTN), via its proatherogenic effect and induction of overexpression of angiotensin converting enzyme. Oxidative stress (OS) upregulates the expression of MDK and MDK induces propagation of neoangiogenesis and acts as chemotactic for neutrophils.
Previous studies demonstrated that Placental Growth Factor (PIGF) and Vascular Endothelial Growth Factor (VEGF) produced by trophoblast cells decreases during Preeclampsia, whereas soluble fms-like tyrosine kinase-1 (sFlt-1), an antiangiogenic factor, increases. The ratio sFlt-1/PlGF has a higher positive predictive value than the isolated measurement. A ratio under 38 exclude risk of imminent preeclampsia and allows to outpatient follow-up with a negative predictive value of 99.3%. A ratio equal or higher than 38 permits to direct high-risk patients towards hospitalization with a positive predictive value of 36.7% of preeclampsia at 4 weeks. These findings suggest that the ratio can be used to select more appropriately women needing hospitalization for suspected preeclampsia.

This is a single-center prospective and observational study conducted from the 1rst of October 2019 to the 27th of January 2021, including pregnant women suspected of preeclampsia, above 24 weeks of gestation. Values were measured using the Elecsys sFlt-1/PlGF immunoassay ratio. The aim of the study is to observe the clinical decision regarding hospitalization, intensive patient monitoring, corticosteroid administration, and labor induction before and after knowing the ratio value
Evaluation of the predictability of estimated levels of Serpin C, sFlt-1 and placental growth factor (PLGF) in blood samples obtained during the 1st trimester from normotensive pregnant women for identification of women liable to develop PE during the course of pregnancy.
Preeclampsia/eclampsia is part of a spectrum of multi-systemic pregnancy disorder that contributes substantially to maternal and perinatal morbidity and mortality, especially in low resource setting. This study was done in Abakaliki, Ebonyi State, Southeast Nigeria. To compare the efficacy of loading dose of magnesium sulphate with that of the Pritchard regimen in the prevention of eclampsia in severe preeclampsia and recurrent fits in eclampsia in a low resource setting. A prospective, single blinded randomized controlled study of loading dose versus Pritchard regimens of MgSO4 at the Teaching Hospital Abakaliki. One hundred and twenty patients were recruited 60 to each arm using computer-generated numbers. Sociodemographic characteristics, efficacy and adverse effects of the drug on the mother and baby were noted.
In this study, the investigator aim was to compare Cathepsin B and Pentraxin 3 levels measured from maternal serum of pregnant women diagnosed with preeclampsia in the second trimester, the effects of these levels on maternal/ fetal outcomes and the composite results of Cathepsin B and Pentraxin 3 levels alone or together and contribute to the literature in this area.
tetrahydrobiopterin (BH4) is degraded by several enzymes, including BH4 oxidase and peroxidases. Several factors can affect its synthesis and degradation. BH4 deficiency or depletion and genetic variations in the genes involved in BH4 metabolism have been associated with hypertension, suggesting that BH4 may play a role in the pathogenesis of hypertension. The maternity center of Tunis ( CMNT ) is a level 3 maternity center, supporting over 12 000 births yearly, where the caesarean section's rate is very high, close to 45% of deliveries. Early detection of these patients can help control maternal and neonatal safety outcomes. we can avoid complications such as severe preeclampsia, HELLP syndrom and eclampsia for the mother, and preterm delievery and fetal growth restriction for the new born. in the literature, studies have reported a decrease in BH4 levels in pregnant women compared to non-pregnant women and others showed that its deficiency or depletion has been associated with hypertension. Moreover, tetrahydrobiopterin administration has been studied as a potential treatment for preeclampsia but the optimal dose has not yet been determined, and further studies are needed to determine the appropriate dose, timing, and duration of BH4 supplementation in this context. Thus, BH4 blood levels as a mean of screening, could enrich our diagnostic arsenal. The purpose of our study is to compare BH4 levels between preeclamptic and normotensive women.
Preeclampsia is a serious condition that can occur during pregnancy and can pose problems for both the mother and the baby. It occurs in approximately 2-8% of all pregnancies globally and is caused by issues with blood vessels, leading to elevated blood pressure and other related health concerns. Additionally, insufficient nutrition and inflammation within the mother's body may contribute to the development of preeclampsia. The HALP score serves as a tool to assess various elements within the blood, indicating inflammation or inadequate nutrition. Although it has been utilized in other medical contexts, its application during pregnancy remains limited. The HALP score has been employed to predict the emergence of ailments such as heart disease and cancer. Given that preeclampsia can stem from inflammation and poor nutrition, the potential of the HALP score in predicting the likelihood of preeclampsia during pregnancy is being examined through research.
The aim of the project is to assess the association between exposure to per- and polyfluoroalkyl substances (PFAS) via drinking water in pregnancy and birth outcomes (i.e. growth retardation, premature birth, and congenital developmental defects) and maternal morbidity (gestational hypertension, diabetes and preeclampsia) in a prospective population-wide register study.
The aim of this study is to assess the effect of a lower treatment threshold for antihypertensive medication and tighter blood pressure control, using remote blood pressure monitoring, on reducing Emergency Room visits for our postpartum patients with hypertensive disease.
