Objectives: Eclampsia is a leading contributor to global maternal morbidity and mortality. Past studies demonstrate varying relationships between demographic and antenatal factors and subsequent development of eclampsia. This study sought to identify predictors of eclampsia in a tertiary hospital in Ghana.
Study Design: Participants were women admitted to Korle Bu Teaching Hospital in Ghana with a diagnosis of preeclampsia with severe features or eclampsia. Medical and obstetric history were extracted from medical records. Clinical information, including vital signs and maternal complications, was prospectively collected.
Main Outcome Measures: Bivariate analysis compared demographic, antenatal, obstetric history, and clinical characteristics between patients presenting with eclampsia and preeclampsia. Multivariable logistic regression identified independent predictors of eclampsia.
Results: Among 1,176 participants, 116 (9.9 %) had a diagnosis of eclampsia. The majority of women with eclampsia experienced their first seizure antepartum (68.7 %), in a location outside a health facility (56.5 %), and witnessed by a family member (55.9 %). Women with eclampsia had a median of 1.0 seizure (IQR 1.0, 2.0). Only 15 (12.9 %) had a prior diagnosis of preeclampsia. There was a nearly threefold increased odds of eclampsia in women aged <20 (aOR 2.75, 95 % CI 1.10-6.89, p = 0.03) and those with twin pregnancy (aOR 2.59, 95 % CI 1.26-5.32, p = 0.01). Decreased odds of eclampsia was observed with age ≥35 (aOR 0.32, 95 % CI 0.15-0.67, p = 0.002), obesity (aOR 0.44, 95 % CI 0.25-0.77, p = 0.004), and chronic hypertension (aOR 0.38, 95 % CI 0.17-0.86, p = 0.02).
Conclusions: Understanding predictors of eclampsia is important to identify high-risk patients and make informed decisions about antenatal care.

Introduction: Preeclampsia (PE) is a common vascular pregnancy disorder affecting maternal and fetal metabolism with severe immediate and long-term consequences in mothers and infants. During pregnancy, metabolites in the maternal circulation pass through the placenta to the fetus. Meconium, a first stool of the neonate, offers a view to maternal and fetoplacental unit metabolism and could add to knowledge on the effects of PE on the fetus and newborn.

Background: Pre-eclampsia (PE) is a gestational disorder that significantly endangers maternal and fetal health. Transfer ribonucleic acid (tRNA)-derived small RNAs (tsRNAs) are important in the progression and diagnosis of various diseases. However, their role in the development of PE is unclear.

Pregnant women living with HIV (PWLWHIV) are at an increased risk of developing obstetrics complications such as pre-eclampsia (PE). Antiretroviral therapy (ART) remains the standard treatment for PWLWHIV and non-pregnant women. However, its use has been associated with adverse liver conditions, particularly hepatotoxicity, often marked by elevated liver enzymes (LEEs) as demonstrated by an increased aspartate transferase (AST), alanine transaminase (ALT), and alkaline phosphatase (ALP) in PWLWHIV on ART.

Neurofibromatosis is a genetic disorder arising de novo or with an autosomal dominant transmission that typically presents either at birth or in early childhood, manifesting through distinctive clinical features such as multiple café-au-lait spots, benign tumors in the skin, bone enlargement, and deformities. This literature review aims to resume the spectrum of maternal and fetal complications encountered in pregnant women with neurofibromatosis type 1 (NF1). Thorough research was conducted on databases such as Web of Science, PubMed, Science Direct, Google Scholar, and Wiley Online Library.

Eclampsia is a multisystem disorder of pregnancy and the puerperium. Posterior reversible encephalopathy syndrome (PRES), a neurotoxic condition characterized by various neurological symptoms, can arise from multiple causes including eclampsia. Although hemorrhage is a possible complication of PRES, subarachnoid hemorrhage (SAH) is a rare occurrence in eclamptic patients with this condition.
