[Study on different onset patterns and perinatal outcomes in severe preeclampsia]

Area of Science:

• Obstetrics and Gynecology
• Maternal-Fetal Medicine
• Perinatology

Context:

• Severe preeclampsia is a significant cause of maternal and perinatal morbidity and mortality.
• Understanding the clinical onset patterns of severe preeclampsia is crucial for timely intervention and improved outcomes.
• This study investigates the distinct clinical presentations and their associations with maternal and fetal health in severe preeclampsia.

Purpose:

• To investigate the clinical onset patterns of severe preeclampsia.
• To compare maternal and perinatal outcomes between early- (< or = 34 weeks) and late-onset (> 34 weeks) severe preeclampsia.
• To analyze the impact of abrupt versus gradual onset on complications and mortality.

Summary:

• A prospective study of 173 severe preeclampsia cases identified abrupt onset in 16.2%.
• Abrupt onset, regardless of gestational age, was associated with significantly higher rates of serious maternal complications (100%) and perinatal mortality compared to gradual onset.
• Early onset severe preeclampsia (before 32 weeks) was significantly linked to poorer maternal and perinatal outcomes.

Impact:

• The findings highlight that abrupt onset of severe preeclampsia is a critical indicator of high risk for severe maternal complications and perinatal death.
• Establishing an early onset clinical delimitation at 32 weeks gestation can help identify high-risk pregnancies requiring closer monitoring and management.
• This research provides valuable insights for clinical decision-making and risk stratification in the management of severe preeclampsia.
