Free amino acid patterns of cerebrospinal fluid in infants and children with various types of convulsive disorders were compared with those in age-matched normal subjects. The total free amino levels in Lennox syndrome were higher than the normal values, and those in infantile spasms controlled by ACTH were higher than those in uncontrolled infantile spasms. Although the levels of only one or two amino acids in tonic-clonic seizure, focal seizure and febrile seizure were higher or lower than those of the controls, the levels of 8 amino acids in infantile spasms were lower and those of 10 amino acids in Lennox syndrome were generally higher compared to the controls. Among amino acids in CSF of children with tonic-clonic seizure, infantile spasms or Lennox syndrome, only the ornithine level was commonly lower than that of the controls. After the treatment, in tonic-clonic seizure, the levels of taurine, asparagine and glycine were increased, and in infantile spasms, those of asparagine, glutamine, glycine, alanine, phenylalanine, lysine and arginine were increased while that of taurine was decreased. These results suggest that each type of convulsive disorder shows the specific amino acid pattern, and the effects of anticonvulsants may be partially understood through the changes of the free amino acid patterns in the brain.

The ratio of glutamine to homocarnosine (G/H ratio) in CSF of children with meningeal pathology or convulsions was measured and the following results were obtained. 1. The mean G/H ratio of normal subjects was 83.0 +/- 41.4. 2. The mean G/H ratios of the patients with bacterial meningitis and meningeal leukemia were 115.9 +/- 81.9 and 115.2 +/- 49.2, respectively. Significant differences were found between those in normal subjects and these diseases. 3. The mean G/H ratio of the patients with viral meningitis was 80.0 +/- 35.1 and no significant difference was found between normal subjects and these patients. 4. The mean G/H ratios in the patients with controlled versus uncontrolled epilepsy were 130.9 +/- 67.1 and 74.8 +/- 49.4, respectively. A significant difference was found between normal subjects and the patients with controlled epilepsy. 5. The mean G/H ratio in the patients with febrile convulsions was 46.5 +/- 6.3. A significant difference was found between normal subjects and these patients. These data suggest that a high G/H ratio in CSF may indicate the excited state of the brain.

Cerebrospinal fluid (CSF) amino acid concentrations were measured in 45 children with acute lymphoblastic leukemia (ALL). Central nervous system (CNS) disease was absent in 34 and present in 11 (Groups L and M, respectively) at diagnosis. Thirty-two otherwise healthy children with febrile convulsions were studied for comparison. Results from this study show that glutamine levels at Day 0 were significantly higher in patients than in controls. Patients in Group M had elevated glutamine levels compared to Group L. In comparison, at Day 14, concentrations of glutamine and asparagine decreased, while glutamic acid amounts increased significantly in Group L. Glutamine levels fell at Day 42 in Group M, which may have resulted from more intensive treatment. From this study we hypothesise that higher baseline glutamine levels are indicative of a greater risk for CNS leukemia. Large-scale prospective trials are required to confirm increased baseline CSF glutamine levels in ALL patients, to identify glutamine as a marker for CNS disease and to clarify underlying mechanisms regulating glutamine in ALL.

Febrile seizures are the most prevalent type of seizures among children up to 5 years of age (2-4% of Western-European children). Complex febrile seizures are associated with an increased risk to develop temporal lobe epilepsy. To investigate short- and long-term effects of experimental febrile seizures (eFS), we induced eFS in highly febrile convulsion-susceptible C57BL/6J mice at post-natal day 10 by exposure to hyperthermia (HT) and compared them to normotherm-exposed (NT) mice. We detected structural re-organization in the hippocampus 14 days after eFS. To identify molecular candidates, which entrain this structural re-organization, we investigated temporal changes in mRNA expression profiles eFS 1 hour to 56 days after eFS. We identified 931 regulated genes and profiled several candidates using in situ hybridization and histology at 3 and 14 days after eFS. This is the first study to report genome-wide transcriptome analysis after eFS in mice. We identify temporal regulation of multiple processes, such as stress-, immune- and inflammatory responses, glia activation, glutamate-glutamine cycle and myelination. Identification of the short- and long-term changes after eFS is important to elucidate the mechanisms contributing to epileptogenesis.
