Filter by:Preeclampsia 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.
Aims: Pre-eclampsia is one of the leading causes of maternal and perinatal morbidity and mortality worldwide. Preeclampsia frequency is 2-8% from all pregnancies. Dietary factors and dietary status have been suggested to play a role in development of preeclampsia. Low intake of nutrients such as calcium, vitamin D, magnesium, omega 3 fatty acids, is related to increased risk of preeclampsia. Also high triglyceride levels, high BMI, low Omega 6: omega 3 ratio and high calories consumption are possible risk factors. Material and Methods: A prospective study will be carried out. Woman medically diagnosed as high risk for preeclampsia will randomly be assigned to dietary treatment or no dietary treatment groups. In the dietary treatment group, besides medical care, all woman will get calcium and vitamin D supplementation from 8th to 16th gestational weeks, and thereafter until delivery personal extensive nutritional guidance. A 3 day food diary will be collected at inclusion and thereafter at Gestational weeks 16 and 28. All routinely collected data during pregnancy (blood tests, weight, blood pressure and preeclampsia symptoms) will be documented. In both groups incidence of pre-eclampsia and eclampsia, blood pressure and protein in urine will be recorded.
The Aim of this study is to determine the relationship between serum concentrations of cancer antigen-125 (CA-125) and pre-eclampsia severity.
This study aims at evaluating the effect of adding magnesium sulphate epidurally as an adjunct to levobupivacaine on the quality of anesthesia and perioperative pain relief in patients with preeclampsia undergoing elective caesarian section (CS).
The purpose of this study is to determine the prevalence of positive antiphospholipid antibodies among women with preeclampsia and to determine the effect of antiphospholipid antibodies on the severity of preeclampsia and the obstetric outcomes
Investigators hypothesize that a) probiotics decrease the overall inflammatory state in the pregnant woman, especially in women with high risk pregnancies.
Adaptation of the maternal immune system to accommodate the semi-allogeneic fetus is necessary for pregnancy success. Dysregulation of this immune adaptation is implicated in reproductive disorders as infertility, recurrent miscarriage, fetal growth restriction, and preeclampsia. The mechanisms being responsible for fetal tolerance are not known. Several T cell subsets have been implicated in fetal tolerance. The effects of preeclampsia on memory cells are not known. The main objective of this study is to analyze the effect of preeclampsia on levels of immune cells.
To find out if lower levels of vitamin D is more prevalent in preeclamptic women
In view of both endothelial injury in pre-eclampsia, high blood pressure and kidney impairment characteristics, a recent study demonstrated that the serum levels of NGAL increased at the end of the second trimester in women who subsequently developed pre-eclampsia compared to the control group. This correlates well with the endothelial damage that occurs during pre-eclampsia and thus NGAL can be considered as a promising marker in predicting both early and late onset pre-eclampsia. It may be required to combine one or more biomarker with NGAL to increase the precision, and sensitivity for detection of risk and reliability of using biomarkers for pre-eclampsia.
Pregnant mothers who develop high blood pressure and other vascular problems (preeclampsia) deliver babies with increased neonatal health problems, which include lung disease and vascular complications, later in life. Investigators will evaluate whether infants of mothers with preeclampsia have evidence for impaired development of the lungs and blood vessels.
