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.
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.
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.
To determine if women can understand the instructions, carry out the test, and interpret the test results. Women will be recruited to complete a test instruction and comprehension assessment and a usability assessment.
A case-control study will evaluate the clinical utility of the Congo Red test GV-005 in following women with a clinical diagnosis of preeclampsia and clinically healthy women in the postpartum period
