AI Article Synopsis
- Hypertensive disorders during pregnancy account for 14% of maternal deaths, notably in low- and middle-income countries, prompting this study to analyze outcomes for women with pre-eclampsia in South Africa.
- Results from a study of 1547 women revealed that 1% died, with significant rates of eclampsia (9.5%), kidney injury (17.6%), and high perinatal death (21%), primarily due to stillbirths.
- Key predictors of severe outcomes included young maternal age and low BMI for eclampsia, high blood pressure for kidney problems, and early admission for perinatal death, indicating a need for targeted interventions.
Article Abstract
Background: Hypertensive disorders of pregnancy contribute to 14% of all maternal deaths, the majority of which occur in low- and middle-income countries. The aim of the study was to describe the maternal and perinatal clinical outcomes of women with pre-eclampsia living in middle- and low-income countries.
Methods: The study was a prospective observational study of women with pre-eclampsia (n = 1547, 42 twin pregnancies) at three South African tertiary facilities. Using stepwise logistic regression model area under the receiver operating characteristic curve (AUROC) values, the association between maternal baseline and admission characteristics and risk of adverse outcomes was evaluated. Main outcome measures were eclampsia, kidney injury and perinatal death.
Results: In 1547 women with pre-eclampsia, 16 (1%) died, 147 (9.5%) had eclampsia, four (0.3%) had a stroke and 272 (17.6%) had kidney injury. Of the 1589 births, there were 332 (21.0%) perinatal deaths; of these, 281 (84.5%) were stillbirths. Of 1308 live births, 913 (70.0%) delivered <37 completed weeks and 544 (41.7%) delivered <34 weeks' gestation. Young maternal age (AUROC = 0.76, 95% confidence interval (CI) = 0.71-0.80) and low Body Mass Index BMI (AUROC 0.65, 95% CI = 0.59-0.69) were significant predictors of eclampsia. Highest systolic blood pressure had the strongest association with kidney injury, (AUROC = 0.64, 95% CI = 0.60-0.68). Early gestation at admission was most strongly associated with perinatal death (AUROC = 0.81, 95% CI = 0.77-0.84).
Conclusions: The incidence of pre-eclampsia complications, perinatal death and preterm delivery in women referred to tertiary care in South Africa was much higher than reported in other low- and middle-income studies and despite access to tertiary care interventions. Teenage mothers and those with low BMI were at highest risk of eclampsia. This information could be used to inform guidelines, the research agenda and policy.

Background: Preeclampsia (PE) is marked by hypertension and detrimental sterile inflammatory response. Despite the reported anti-inflammatory effect of pyridostigmine bromide (PYR) in different models, its anti-inflammatory mechanism in PE is unclear. This study assessed whether such an anti-inflammatory effect involves inhibition of placental Toll-like receptor 4 (TLR4) signaling.

Background: Maternal agonistic autoantibodies against the angiotensin II type 1 receptor (AT1-AAs) have been implicated in the pathophysiology of preeclampsia, but their presence in their offsprings and their possible neonatal effects have not been specifically explored. This prospective study aimed to evaluate the presence of AT1-AAs and their potential clinical effects in neonates of AT1-AAs positive mothers.
Methods: Women with preeclampsia and their neonates were included.

Preeclampsia (PE) is a complex pregnancy syndrome characterized by hypertension with or without proteinuria, affecting 2-6% of pregnancies globally. PE is characterized by excessive release of damage-associated molecular patterns (DAMPs) into the maternal circulation. This DAMP-rich milieu acts on innate immune cells, inducing a proinflammatory state characterized by elevated cytokines such as IL-1β and IL-18.

Background: Preeclampsia (PE) is a pregnancy-specific, multisystemic disorder that affects 2-8% pregnancies worldwide and is a leading cause of maternal and perinatal mortality. At present, there is no cure for PE apart from delivery the placenta. Therefore, it is important and urgent to possess a suitable animal model to study the pathology and treatment of PE.

Background: Due to the global growth of its prevalence and its impact on patient health, obesity is considered a near-epidemic condition by the World Health Organization (WHO). Its overall prevalence has now reached 17 % in France. The impact of obesity is also a concern for pregnant women, due to the risk of maternal and fetal complications.
