Serum and CSF biomarkers in acute pediatric neurological disorders

  1. 1. Serum and CSF biomarkers in acute pediatric neurological disorders Aim To validate serum and cerebrospinal fluid (CSF) biomarkers for diagnosis and prognosis estimations. Conclusions Both CSF and serum tTau levels could be useful, but mediocre at best. Further studies are clearly needed to find better biomarkes or other way around. (^o^) This paper is published in Brain Dev. 2014;36:489-95. E-mail: shiihara-ind@umin.net Methods Serum CSF S100B, neuron-specific enolase (NSE), and total tau (tTau) were measured in various acute pediatric neurological disorders. Their usefulness was validated using receiver operating characteristic (ROC) curves and area under the curve (AUC) analysis.

CSF and serum tTau levels could be good predictors for diagnosis (CSF tTau; AUC = 0.76) and prognosis (serum tTau; AUC = 0.78). Diagnostic categories were as follows; acute encephalitis/encephalopathy (AEE), aseptic meningitis (AM), afebrile seizures (AS), controls (CTR), febrile seizures (FS), and septic meningitis (SM).
