Diagnostische Wertigkeit von Protein S100 und Neuronenspezifischer Enolase bei Patienten mit spontaner Subarachnoidalblutung

Maud Ilschner
Neuron specific Enolase (NSE) and S100B protein have been shown to be increased in cerebrospinal fluid (CSF) and serum of patients suffering from subarachnoid hemorrhage (SAH). The present study was designed to evaluate the accuracy of NSE and S100B from CSF and serum for the prognosis of outcome and the detection of secondary complications as cerebral infarction, vasospasm and intracranial hypertension. In 55 patients suffering from spontaneous SAH and requiring immediate external ventricular

At hospital discharge patients� outcome was assessed and the occurrence of cerebral infarction, vasospasm and intracranial hypertension was registered. Mean and peak values of each parameter for each patient were calculated. For accuracy assessment receiver operating characteristics were used. Bad outcome was found in 33 patients. Cerebral infarction, vasospasm and intracranial hypertension was found in 31 (56%), 34 (62%) and 36 (65%) patients. Mean and peak values of NSECSF (p<0.001), S100BCSF (p<0.001) and S100BSerum (p<0.001) but not of NSESerum provided the ability to distinguish between patients with good and bad outcome. The accuracy of NSECSF and S100BCSF did not differ significantly from that of S100BSerum. NSECSF (p<0.001), S100BCSF (p<0.001) and S100BSerum (p<0.001) allowed the detection of cerebral infarction and intracranial hypertension. Cerebral vasospasm was detected by none of the parameters under investigation. In conclusion, NSECSF, S100BCSF and S100BSerum provide similar prognostic values for outcome, intracranial hypertension and cerebral infarction. Worse results were found for NSESerum.
