Neopterin is synthesized mainly by monocytes/macrophages and is considered to be a marker for activation of the cellular immune system. It has been reported that cerebrospinal fluid (CSF) neopterin levels are significantly higher in patients with bacterial meningitis than in those with aseptic meningitis or non-pleocytotic CSF. In this study levels of neopterin and interferon-gamma (IFN-gamma) were measured in children with non-pleocytotic CSF. The CSF neopterin levels were significantly higher in patients with typical febrile convulsions (FCs) (15.0 +/- 4.5 nmol/l) than in those with pyrexia without convulsions (6.5 +/- 2.7 nmol/l) or convulsions without pyrexia, namely, epilepsy (4.8 +/- 2.4 nmol/l). The CSF neopterin/serum neopterin ratio (C/S ratio) was also higher in patients with typical FCs (1.54 +/- 0.83) than in those with pyrexia without convulsions (0.32 +/- 0.18) or convulsions without pyrexia (0.77 +/- 0.28). Patients with prolonged FCs tended to have higher CSF neopterin levels than those with typical FCs. There was also a tendency for CSF IFN-gamma levels to be higher in patients with FCs than in those with pyrexia without convulsions or convulsions without pyrexia. The results of the present study suggest that some immune activation in the central nervous system (CNS) compartment may be related to the mechanisms of FCs.

It is well known that an acute encephalopathy occasionally follows prolonged febrile seizures. We measured the concentrations of interferon-gamma, tumor necrosis factor-alpha (TNF-alpha), interleukin-2 (IL-2), IL-4, IL-6, IL-10, and soluble TNF receptor 1 (sTNFR1) in serum and CSF during the acute stage in 13 children with acute encephalopathy following prolonged febrile seizures (AEPFS) and 23 with prolonged febrile seizures without encephalopathy (PFS) to investigate the pathogenesis of AEPFS. Serum IL-6, IL-10, sTNFR1, and CSF IL-6 levels were significantly higher in AEPFS and PFS compared with control subjects. CSF IL-6 levels in AEPFS were significantly higher than those in PFS, but not serum IL-6, IL-10, or sTNFR1. The CSF IL-6 levels were significantly higher than the serum levels in AEPFS, but not PFS. The serum levels of sTNFR1 and IL-10 were significantly higher than those in the CSF in AEPFS and PFS. The serum IL-10 and sTNFR1 levels in patients who did not experience a second seizure were significantly higher than those in patients who experienced a second seizure, which was characterized by clusters of complex partial seizures several days after the initial prolonged febrile seizure. Our results suggest that serum IL-6, IL-10, TNF-alpha, and CSF IL-6 are part of the regulatory system of cytokines in AEPFS.

We identify possible differences in the cytokine/chemokine profiles in cerebrospinal fluid (CSF) from children with encephalopathy and febrile seizure. Interleukin (IL)-1beta, 2, 4, 5, 6, 7, 8, 10, 12, 13, 17, interferon-gamma, tumour necrosis factor-alpha, granulocyte colony-stimulating factor, granulocyte monocyte colony-stimulating factor, monocyte chemoattractant protein-1 and macrophage inflammatory protein-1beta were measured simultaneously in CSF supernatants from children with encephalopathy (n = 8), febrile seizure (n = 16) and fever without neurological complications (n = 8). IL-8 in CSF from children with encephalopathy was significantly elevated compared to that in CSF from children with febrile seizure and fever without neurological complications. IL-8 in CSF was also higher than serum IL-8, suggesting that increased IL-8 was generated from glia cells or astrocytes, not by leakage from serum. Increased IL-8 in CSF in encephalopathy may protect against severe brain damage.
