Pre-eclampsia causes adverse maternal outcomes across the gestational spectrum

Area of Science:

• Obstetrics and Gynecology
• Maternal-Fetal Medicine
• Neonatology

Background:

• Pre-eclampsia (PE) is a serious pregnancy complication characterized by hypertension and organ damage.
• The timing of pre-eclampsia onset may influence maternal and infant outcomes.
• Early onset pre-eclampsia (EOP) is defined as PE developing before 34 weeks of gestation.

Purpose of the Study:

• To compare maternal and infant outcomes in early onset pre-eclampsia (EOP) versus later onset pre-eclampsia.
• To evaluate if term pre-eclampsia is associated with better outcomes than late pre-term or early onset pre-eclampsia.

Main Methods:

• Retrospective analysis of 696 pregnancies with pre-eclampsia from 1991-2011.
• Classification of pre-eclampsia into early onset (EOP), late pre-term, and term groups.
• Assessment of maternal outcomes including severe hypertension, organ injury, and neurological complications, alongside perinatal outcomes.

Main Results:

• Maternal age was comparable across EOP, late pre-term PE, and term PE groups.
• Women with late pre-term and term PE exhibited similar maternal and fetal outcomes.
• While maternal outcomes were similar, infants born to mothers with EOP experienced significantly higher rates of morbidity and mortality.

Conclusions:

• Pre-eclampsia affects maternal organs significantly, irrespective of gestational age at onset.
• Infant outcomes are substantially worse for pregnancies complicated by early onset pre-eclampsia (EOP).
• Pre-eclampsia presenting after 34 weeks generally results in favorable maternal and fetal outcomes in well-equipped facilities.
