Placental Protein 13 Serum Endoglin and Uterine Doppler Indeces as Predictors of Pre-eclampsia
Preeclampsia50 pregnant females were divided in two groups, twenty five as a control group and twenty five as high risk group; they were subjected to uterine artery Doppler, measurement of maternal serum and detection of (MTHFR) gene polymorphisms in first trimester at 11 to 14 weeks of gestation, all pregnancies were followed until 40 weeks for development of pre-eclampsia
Acid-Base and Point of Care Ultrasound in Severe Preeclampsia
Pre-EclampsiaPreeclampsia remains a leading cause of maternal morbidity and mortality, in both the developed and developing world. It is a complex, multisystem disease which, in its severe form, affects the cardiovascular, renal, hepatic, neurological and haematological systems. The University of Cape Town-associated medical institutions alone were responsible for the treatment of 800 women in 2014, who were classified as having preeclampsia with severe features. Given the complexity of the disease, anesthetic management for Caesarean section in these patients remains very challenging. Recent studies have begun to demonstrate novel markers of preeclampsia severity, including point-of-care ultrasound (POC-US) and acid-base (AB) abnormalities. For example, pilot studies have demonstrated that approximately 25% of women diagnosed with severe preeclampsia show signs of increased intracranial pressure and elevated lung water as evaluated by point of care ultrasound. These findings could serve as noninvasive markers of disease severity, and thus may be used to predict maternal and fetal outcome in preeclamptic women. Point of care ultrasound is playing an increasing role in perioperative diagnosis, and newer, less expensive devices are continuously being developed, and will in all likelihood play an important role in South Africa in the near future. In a recent trial performed at the University of Cape Town, a comprehensive acid-base analysis in severe preeclamptic women demonstrated significant abnormalities in independent acid-base determinants. In addition, strong indications were found that changes in acid-base status in preeclampsia are more pronounced earlier in pregnancy and are associated with urgent deliveries. As in other clinical arenas in critically ill patients, acid-base abnormalities are associated with increased lung water, increased intracranial pressure, and outcome, and we hypothesize that similar associations might be found in severe preeclamptic women. Therefore, one aim of this study is to evaluate the association of venous acid base abnormalities (an inexpensive and readily available test) observed in late onset severe preeclampsia and organ manifestations identified with ultrasound, a well-validated and robust tool for identifying these manifestations. Investigators will further examine the association between ultrasound findings and/or venous acid-base abnormalities with urgent delivery. It is intended to do a subsequent comparison between early- and late onset preeclampsia, when a suitable tertiary site has been identified.
Risk Analysis of Intensive Care Mangement on Maternal and Fetal Outcome of Severe Preeclampsia and...
Hypertensive Disorder of PregnancyLaboratory monitoring of patients included serial measurement of complete blood cell count, liver function tests, coagulation profile, and renal function tests. ICU management during conduction of the research study included the following: Control of convulsions using magensium sulphate. Control of blood pressure Diastolic blood pressure above 110 mmHg, nifedipine was administered.A plasma volume expansion with saline was used in all women to maintain sufficient intravascular volume. Delivery was performed immediately after hemodynamic stabilization and clinical control of general condition .

PreeclampsiaSample Collection Study
Placental Volume, Flow, and Vascularity Study
Pre-EclampsiaThe purpose of this preliminary study is to implement an automated and standardized computer-based method that accurately measures placental volume, blood flow, and vascularity. This will be accomplished by using the digital data obtained at the time of a first-trimester 3D image volume. This information will then be used to further investigate whether placental volume, blood flow, and vascularity can be used to predict the risk of preeclampsia in conjunction with maternal history and serum blood markers obtained at the time of their ultrasound.
Vitamin D in Pregnancy
Vitamin D DeficiencyPre-Eclampsia2 moreDanish pregnant women are recommended ad daily vitamin D supplement of 10 µg. Despite the fact that 9 out of 10 women take vitamin D supplements, more than 40% of pregnant women are vitamin D deficient, putting them at an increased risk of pregnancy complications like fetal growth restriction and pre-eclampsia. Our hypothesis is that pregnant women would benefit from an increased intake og vitamin D and that an intake of 90µg/day can reduce the prevalence of placenta-related pregnancy complications. Combining a double-blinded randomized trial (10µg vs.90µg) with collection of placental material, we want to test if the prevalence of pregnancy complications is reduced and explore how vitamin D affects placenta to improve our understanding of the disease pathology and risk factors.
Obstetric Antiphospholipid Antibody Syndrome : Contribution of the Evaluation of ADAMTS13 Made at...
Antiphospholipid Antibody Syndrome in PregnancyStudy based on data concerning the first pregnancy treated and followed up after the diagnosis of oAPS in the NOH-APS cohort, according to clinical results already published; and on a thematic library collected and preserved at the time of the positive pregnancy test. ADAMTS 13 will be explored in the available samples defined above: ADAMTS13 antigen (presence of the molecule), ADAMTS13 activity (VWF proteolysis activity of the molecule), global autoantibodies against ADAMTS13 (plasma antibodies recognizing solid phase insolubilized ADAMTS13), these 3 parameters for the description of ADAMTS13 being measured using commercially available diagnostic kits, ELISA type, Technozyme® range, Technoclone, Vienna, Austria. The clinical endpoint evaluated will be the occurrence (yes/no) of preeclampsia, which is assessed globally, all subtypes combined. Then evaluated according to subtype: late preeclampsia from 34 weeks, early preeclampsia before 34 weeks, eclampsia (convulsions), HELLP syndrome, preeclampsia associated with the birth of a small-for-gestational-age child (defined at percentile 10 of the tables adjusted for gestational age and sex; severe: defined at percentile 3), preeclampsia associated with a retro-placental hematoma, ...
Soluble Factors and Renal Outcome in Preeclampsia
PreeclampsiaRenal FunctionPreeclampsia (PE) is an important complication of pregnancy and can lead to chronic kidney disease by causing endothelial damage and podocyte loss, Soluble forms-like tyrosine kinase-1 (sFlt-1), placental growth factor (PlGF), sFlt1 / PlGF ratio and endoglin are the biomarkers for the differential diagnosis of preeclampsia and other diseases. We aim to explore the correlation of these biomarkers with long term renal function, blood pressure and urine albumin creatinine ratio (UACR) in PE patients.
Haptoglobin and Preeclampsia
PreeclampsiaThe purpose of this study is to show that a certain protein called haptoglobin protects against preeclampsia which is a common pregnancy complication.
