Cerebrospinal fluid (CSF) from 8 patients with symptomatic infantile spasms was collected before specific treatment for infantile spasms. The concentration of CSF kynurenic acid (KYA) and 3-hydroxykynurenine (3-OHKY) in infantile spasms was analyzed by high-performance liquid chromatography and compared with CSF KYA from 10 age-matched controls. The levels of CSF KYA were significantly lower in infantile spasm patients compared to controls (P < .05). In contrast, the levels of CSF 3-OHKY were significantly higher in infantile spasm patients than in controls (P < .05). These findings suggest that the presence of seizures in infantile spasms is associated with altered metabolism of 3-OHKY. The possibility that seizures may be related to increased or decreased production of certain kynurenine metabolites is discussed.
