In the general study of antipyretic products for children prone to febrile convulsions, the authors describe the results obtained administering, the rectal route, three different doses of lysine acetylsalicylate (20-30-40 mg/kg/b.w.) to 53 children with fever. The lower dose was often inadequate in these patients, who need a quick reduction of body temperature below 38 degrees C. The two higher doses were useful both in clinical and in statistical terms, without relevant differences between groups. A statistically significant inverse correlation between blood levels of salicylates and temperature was also shown. No undesirable side effects were observed. The authors conclude that ASL, by rectal route, has to be considered a drug of choice for this indication.

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.

To determine the involvement of oxidative stress in the pathogenesis of acute encephalopathy associated with human herpesvirus-6 (HHV-6) infection, we measured the levels of oxidative stress markers 8-hydroxy-2'-deoxyguanosine (8-OHdG) and hexanoyl-lysine adduct (HEL), tau protein, and cytokines in cerebrospinal fluid (CSF) obtained from patients with HHV-6-associated acute encephalopathy (HHV-6 encephalopathy) (n = 16) and complex febrile seizures associated with HHV-6 (HHV-6 complex FS) (n = 10). We also examined changes in CSF-8OHdG and CSF-HEL levels in patients with HHV-6 encephalopathy before and after treatment with edaravone, a free radical scavenger. CSF-8-OHdG levels in HHV-6 encephalopathy and HHV-6 complex FS were significantly higher than in control subjects. In contrast, CSF-HEL levels showed no significant difference between groups. The levels of total tau protein in HHV-6 encephalopathy were significantly higher than in control subjects. In six patients with HHV-6 infection (5 encephalopathy and 1 febrile seizure), the CSF-8-OHdG levels of five patients decreased after edaravone treatment. Our results suggest that oxidative DNA damage is involved in acute encephalopathy associated with HHV-6 infection.

Epigenetic modifications including histone modifications are associated with seizure development and epileptogenesis; however, its underlying mechanism remains to be elucidated. Dipeptidyl peptidase 4 (DPP4) and IL6 are identified as febrile seizure (FS)-related genes using gene microarray analysis in hyperthermia prone (HP) rats. This purpose of the study focused on exploring whether epigenetic modifications marker histone H3 lysine 27 trimethylation (H3K27me3)-regulated DPP4 and IL6 expression further affected seizures development. Herein, we reported broad between-group differences in the global levels of H3K27me3 with increased seizure severity in vivo. Using chromatin immunoprecipitation (ChIP), we identified markedly decreased H3K27me3 enrichment at their promoters of DPP4 and IL6 in vivo. We further showed that hyperthermia significantly decreased protein levels of H3K27me3, increased mRNA levels of DPP4 and IL6 by decreasing H3K27me3 enrichment at their promoters of DPP4 and IL6 in vitro. Importantly, H3K27me3 loss via enhancer of zeste homolog 2 (EZH2) knockdown promoted expression of DPP4 and IL6 via the same mechanism in vitro. EZH2 knockdown also increased neuronal firing frequency in vitro and FS susceptibility in vivo companied with upregulation expression of DPP4 and IL6. Taken together, our study provided the first evidence that hyperthermia-induced decreased of H3K27me3 promoted seizure susceptibility via regulating the expression pattern of DPP4 and IL6. These findings suggested that the methylation level of H3K27me3 might be a key regulator of seizure susceptibility.
