Summary
Elevated serum S100B protein levels in severe preeclampsia indicate neural damage. This suggests astrocytic release of S100B occurs independently of preeclampsia progression to eclampsia.
Area of Science:
- Neurology
- Obstetrics
- Biochemistry
Background:
- Serum S100B protein is primarily released by astrocytes in the Central Nervous System (CNS).
- Elevated S100B levels are linked to various brain pathologies, including eclampsia in pregnant women.
Purpose of the Study:
- To compare serum S100B concentrations in pregnant women with severe and mild preeclampsia (PE) against normotensive pregnant women.
Main Methods:
- Serum S100B levels were measured using a luminometric assay.
- Participants included normotensive pregnant women (n=15), women with mild PE (n=12), and women with severe PE (n=34).
Main Results:
- Sixty-one women were studied, with a mean age of 26.6 years and gestational age of 33.3 weeks.
- Severe PE group showed significantly higher S100B levels (0.20±0.19 μg/L) compared to mild PE (0.07±0.05 μg/L) and normotensive groups (0.04±0.05 μg/L).
Conclusions:
- Higher serum S100B in severe PE suggests neural damage.
- Astrocytic release of S100B in severe PE may not depend on progression to eclampsia.
