Correlation between cerebral biomarkers and optic nerve sheath diameter in patients with severe preeclampsia.

: To examine the correlation between plasma cerebral biomarkers (S100B and neuron-specific enolase (NSE)) and ultrasonographic optic-nerve-sheath-diameter (ONSD) in preeclampsia. : Thirty preeclampsia patients and 27 controls were included. Mann-Whitney-U test was used for comparison of S100B, NSE, and ONSD in preeclampsia vs. controls. Kendall's tau was used to assess the correlation between biomarkers and ONSD (p < 0.05 significant). : ONSD, S100B and NSE were significantly higher in preeclampsia (p < 0.001, p = 0.004, and p < 0.001, respectively). There was significant correlation between NSE levels and ONSD: Kendall's tau = 0.26; p = 0.01. : S100B and NSE are elevated in severe preeclampsia. NSE correlates with increased ONSD suggesting cerebral edema.
