Role and Expression of MXRA5 in Placental Connective Tissue Remodelling in Preeclampsia
Pre-EclampsiaTo measure the level of expression of MXRA5 and ANXA4 genes in preeclampsia (PE). To detect the effect of heavy metals (lead (Pb) and arsenic (AR)) on these two genes in the pathology of PE. To explore the association of the previous two genes with the heavy metals in link with Phosphoinositide 3-kinases/Protein Kinase B (PI3K/AKT) pathway. To detect Syndecan-1 by immunohistochemical antibodies. To define the role of extracellular matrix remodelling in PE.
İs There a Relationship Between Severity of Preeclampsia and Maternal Heavy Metal Levels?
Mild Pre-eclampsiaSevere PreeclampsiaThe purpose of this study, to investigate whether severity of preeclampsia is associated with altered levels of heavy metals (Cd, Hg, arsenic and Pb) in maternal blood, fetal blood, and maternal hair.
Vascular Changes in Pre-Eclamptic Patients and Its Impact on Pregnancy Outcome.
Pre-EclampsiaNormal pregnancy is associated with vasodilation and decreased peripheral resistance, which is detected as early as 5 weeks' gestation . Pre-eclampsia is a multi-system disorder of the second half of pregnancy , which is characterized by increased vascular reactivity and peripheral resistance with pathological changes that are consistent with impaired blood flow to the affected vascular beds. Investigators will evaluate fetal and maternal vascular changes in normotensive and pre-eclamptic patients by Ultrasound and Doppler and their impact on prediction of pregnancy outcome.
CA-125 and Severity of Pre-Eclampsia
Pre-EclampsiaThe Aim of this study is to determine the relationship between serum concentrations of cancer antigen-125 (CA-125) and pre-eclampsia severity.
Diagnostic Value of MicroRNA 210 In Preeclampsia
Pre-EclampsiaPre-eclampsia is a disorder of pregnancy characterized by hypertension (defined as systolic blood pressure 140mmHg or diastolic blood pressure ⩾90 mmHg) and proteinuria (300 mg or greater in a 24 h urine specimen and/or protein to creatinine ratio of > 0.30) . The disorder usually occurs after 20 weeks of pregnancy and worsens over time. Risk factors for pre-eclampsia include: obesity, prior hypertension, older age, and diabetes mellitus, primigravida and pregnant women with multiple gestation . Healthy women pregnancy can be associated with resistance to the action of insulin on glucose uptake and utilization. Insulin Resistance (IR) is defined as decreased ability of target tissues such as liver, adipose tissue and muscle to respond to normal circulating concentrations of insulin. Insulin Resistance can be a result of a number of factors such as defective molecular structure of insulin, defective receptor functioning or defective signal transduction pathway . Preeclampsia is associated with increased expression of Tumor necrosis Factor α and other inflammatory marker which causes Insulin Resistance. Increased Insulin Resistance leads to dyslipidemia that can worsen the placental ischemia leading to vicious cycle of ischemia-inflammation-Insulin Resistance-dyslipidemia-ischemia . Insulin resistance has also been hypothesized to contribute to the pathophysiology of preeclampsia. Compared to women who have normotensive pregnancies, women who develop preeclampsia are more insulin resistant prior to pregnancy . The recognition that specific miRNAs are induced by hypoxia and are commonly dysregulated in preeclampsia raises the possibility that such miRNAs mediate the adverse effects of placental hypoxia in preeclampsia. MiRNAs present in maternal blood may have the potential to be used as biomarkers, as they are relatively stable and tissue specific . It was found that mir-210 is induced in patients with pre-eclampsia, whether mir-210 contributes to the pathogenesis of pre-eclampsia, a complex disorder widely believed to be associated with placental hypoxia .
Microcirculatory and Tissue and Cerebral Oxygenation in Preeclampsia and Normal Pregnancy: An Observation...
PregnancyEclampsiaPreeclampsia is a disease of pregnancy affecting 3% to 8% of all pregnancies and is a major cause of maternal and perinatal morbidity and mortality. Characterized by alter placentation with subsequent release of inflammatory mediators leading to a generalized endothelial dysfunction. It is now accepted that endothelial dysfunction heralds the clinical manifestations of preeclampsia. The side-stream darkfield (SDF) microscopy device emits a 550 nm green light with a depth region of interest of 500 um. Green light is absorbed by the erythrocytes and appears black. SDF is a well-known non-invasive tool that can study the microcirculatory changes. It was used before in many situations especially in sepsis and septic shock patients. Near-infra-red spectroscopy (NIRS) device, measures the absorbance of near-infra-red (NIR) light by tissues perfused with oxygenated blood, and is capable of measuring changes in parenchymal volume tissues. It was used before in many situations (including pregnant patients) to reflect the tissue oxygenations. The investigators are planning to use the SDF and NIRS tools to study the microcirculatory change in preeclamptic subjects and normal pregnant subjects. If these two devices are able to determine any changes this should stand as a baseline for future studies in this field.
Certain Maternal Antibodies in Relation to Doppler in Hypertension With Pregnancy
Pre-EclampsiaRelation of certain maternal serum antibodies to Doppler changes will be studied in cases suffering from hypertension with pregnancy.
Catestatin and Hypertension in Pregnancy
Pre-EclampsiaEclampsia3 moreCatestatin is a kind of protein involved with cardiovascular disease. Accumulated evidence shows that Catestatin may be a predictor of primary hypertension, but whether it plays the same role in pregnant hypertensive disorders needs to be determined. By measuring the plasma level of Catestatin, main biochemical marks and UCG in healthy pregnancy and pregnancy with hypertension, the research may contribute to this problem.
Impact of Body Mass Index on Serum Maternal and Fetal Magnesium Level
Pre-EclampsiaMagnesium sulphate is an inorganic salt with multiple therapeutic applications in medicine it has been widely utilized and studied on a diverse set of conditions such as asthma, cardiac arrhythmia and stroke. In pregnant women ,MgSo4 has been used in many cases such as for seizures prophylaxis in preeclampsia, tocolysis in preterm labour and for fetal neuroprotection in immenint preterm delivery.MgSo4 has been used as the standard drug for tocolysis in preterm labour and other drugs have been compared to it.
Random Urine Protein-creatinin Ratio to Predict Magnitude of Proteinuria
Pre-eclampsiaThe aim of this study was to evaluate diagnostic accuracy of the spot urinary proteinuria, random urine protein- creatinin ratio for prediction of significant proteinuria (≥ 300 mg/24h) and magnitude of proteinuria in patients with in mild preeclampsia and severe preeclampsia. The cross-sectional longitudinal study design used, 209 patients with pre-diagnosed preeclampsia in which in our inpatients clinic included this study. Random urine samples were taken before the 24 hour urine collection for spot urine analysis for evaluated proteinuria and protein/creatinin ratio. 24 hour urine analysis was performed in all patients as the gold standard of the urine total proteinuria.
