To investigate pediatric brain impairment, beta-endorphin levels, one of the opioid peptides that modulate human high cortical functions, were measured in cerebrospinal fluid (CSF). The study included 19 patients with infantile autism, 3 patients with Rett syndrome, 6 patients with infantile spasms, 16 patients with aseptic meningitis, and 23 age-matched controls. In the control group, the CSF beta-endorphin concentrations were negatively correlated with increasing age. There was no correlation between body temperature and the levels, and no significant difference in the levels according to sex. In infantile autism, the CSF level was not significantly different from that in controls. In Rett syndrome, it was significantly higher, while in infantile spasms it was lower than in controls. In aseptic meningitis, the CSF beta-endorphin level was significantly higher than in controls. The alterations in CSF beta-endorphin levels may play a role in these neurologic disorders and/or in central nervous system (CNS) infections.
