Objective: The aim of this study was to evaluate maternal asymmetric dimethylarginine (ADMA) levels in pregnancies complicated by isolated fetal intrauterine growth restriction (IUGR), in preeclamptic pregnancies with and without IUGR, and in healthy normotensive pregnant women with proper weight fetuses.
Patients And Methods: The study was carried out on 54 normotensive pregnant patients with pregnancy complicated by IUGR, 35 patients with IUGR in the course of preeclampsia, 29 preeclamptic patients with appropriate-for-gestational-age weight infants and 54 healthy normotensive pregnant patients. The ADMA concentrations were evaluated using an ELISA assay.
Results: The preeclamptic women and normotensive patients with pregnancy complicated by isolated IUGR revealed higher levels of maternal serum ADMA. The mean values of maternal serum ADMA were 0.5730 ± 0.1769 μmol/l in the P group, 0.5727 ± 0.1756 μmol/l in the PI group, 0.6129 ± 0.1517 μmol/l in the IUGR group, and 0.5017 ± 0.1116 μmol/l in the control group. The levels of ADMA were additionally higher in the patients with HELLP syndrome and in patients with pregnancy complicated by eclampsia.
Conclusions: It seems that ADMA is an active agent not only in preeclamptic patients, but also in normotensive pregnant women with isolated fetal IUGR and could be a marker of severity of preeclampsia.

Background: In 2017, the American College of Cardiology and American Heart Association (ACC/AHA) lowered blood pressure (BP) thresholds to define hypertension in adults outside pregnancy. If used in pregnancy, these lower thresholds may identify women at increased risk of adverse outcomes, which would be particularly useful to risk-stratify nulliparous women. In this secondary analysis of the SCOPE cohort, we asked whether, among standard-risk nulliparous women, the ACC/AHA BP categories could identify women at increased risk for adverse outcomes.

Background: Thrombocytopenia affects 12-20% of women with preeclampsia and a low platelet count impairs coagulation. Women with preeclampsia have an increased risk of both cerebral hemorrhage, thromboembolism, and postpartum hemorrhage. Studies of platelet function and coagulation in women with preeclampsia show conflicting results.

Background: Sirtuins and FoxO1 are reported to be important in the pathophysiology of preeclampsia. This study aimed to investigate whether serum FoxO1 and SIRT2 concentrations differ between preeclampsia and normal pregnancy and also to compare these markers in early- and late-onset preeclampsia.
Methods: This cross-sectional study was conducted on 27 women with early-onset preeclampsia, 27 women with late-onset preeclampsia, and 26 healthy normotensive pregnant controls.

Introduction: Pre-eclampsia is a pregnancy-related complication estimated to affect up to 8% of pregnancies worldwide. It is associated with an increased risk of postpartum sustained hypertension, coronary artery disease, cerebrovascular disease, peripheral arterial disease and cardiovascular-related mortality. Nevertheless, these associations have seldom been addressed in younger women from sub-Saharan Africa (SSA).
