    Abstract:
    Neuron-specific enolase (NSE) has recently proved to be a useful marker of neuron damage. We determined NSE levels in the serum and CSF of 117 children with various neurological disorders (43 with febrile convulsion, 25 with seizure disorder, 32 with meningitis, 3 with brain tumor, 2 with Reye syndrome, 3 with congenital CNS malformation and 9 with other disorders). The purpose of this study is to assess the potential usefulness of NSE in diagnosis and prognosis. Twenty CSF and serum samples of children without neurological problem served as a control. The mean values of the NSE levels in the CSF and serum of the control group were 5.00 +/- 1.65 ng/ml and 8.34 +/- 4.40 ng/ml respectively. The peak values were found in cases with brain tumor. A patient died of Reye syndrome didn't show a very high level of NSE in the serum or CSF. However, we found significant differences in NSE levels between the patients with febrile convulsions and those with seizure disorders (non-febrile, abnormal EEG). Most of our patients with febrile convulsions were cases of simple febrile convulsion, and their NSE levesin the CSF and serum were 4.55 +/- 1.00 and 8.06 +/- 3.18 ng/ml. Cases with non-febrile seizure disorders had significantly higher level of NSE in both CSF and serum (P less than 0.05). Patients with purulent meningitis usually had higher levels than those with aseptic meningitis. Our study can be summarized thus: 1. A normal level of NSE does not exclude severe neuron damage.(ABSTRACT TRUNCATED AT 250 WORDS)
