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.

D008582	Meningitis, Aseptic	A syndrome characterized by headache, neck stiffness, low grade fever, and CSF lymphocytic pleocytosis in the absence of an acute bacterial pathogen. Viral meningitis is the most frequent cause although MYCOPLASMA INFECTIONS; RICKETTSIA INFECTIONS; diagnostic or therapeutic procedures; NEOPLASTIC PROCESSES; septic perimeningeal foci; and other conditions may result in this syndrome.

D001321	Autistic Disorder	A disorder beginning in childhood. It is marked by the presence of markedly abnormal or impaired development in social interaction and communication and a markedly restricted repertoire of activity and interest. Manifestations of the disorder vary greatly depending on the developmental level and chronological age of the individual.

D001615	beta-Endorphin	A 31-amino acid peptide that is the C-terminal fragment of BETA-LIPOTROPIN. It acts on OPIOID RECEPTORS and is an analgesic. Its first four amino acids at the N-terminal are identical to the tetrapeptide sequence of METHIONINE ENKEPHALIN and LEUCINE ENKEPHALIN.	Endorphin, beta,beta-Endorphin (1-31),beta Endorphin
