Decreased cerebrospinal fluid levels of beta-endorphin and ACTH in children with infantile spasms

J Neural Transm (Vienna). 2001;108(3):363-71. doi: 10.1007/s007020170081.

Abstract

To investigate the pathophysiology of infantile spasms (IS), we measured the cerebrospinal fluid (CSF) levels of beta-endorphin (beta-EP), adrenocorticotropic hormone (ACTH), and corticotropin-releasing hormone (CRH) in 20 patients with IS, including 11 with the secondary form and 9 with the cryptogenic form of the disease. The findings were compared with those obtained in age-matched controls without neurologic disease. The CSF levels of beta-EP and ACTH were significantly lower in patients with IS than those in the controls. The CSF levels of CRH in patients with IS were lower, although, this trend was not significant. These reductions in the CSF levels of these neuropeptides could explain the impairment of the brain-adrenal axis in such patients. These results might support the hypothesis that, instead of originating from an increased abundance of CRH, which can act as a rapid and potent convulsant, some infantile seizures could be caused by an ACTH deficiency.
