Adrenocorticotropic hormone (ACTH) therapy is effective for West syndrome; however, the underlying mechanism of action remains unknown. This study explored this mechanism in 5 Japanese patients with West syndrome, injected with ACTH for 28 days. Serum samples were obtained before and 30, 120, and 720 minutes after ACTH injection divided into an "early" (1-4 days) and a "late" (10-28 days) group. Responses to ACTH over time were analyzed by measuring the levels of 27 cytokines. In the early group, serum levels of interleukins-5, -9, and -17, basic fibroblast growth factor, interferon (IFN-γ), IFN-γ-inducible protein 10, chemokine ligand (CCL) 3 and 4, and platelet-derived growth factor were higher in all patients before ACTH administration than in the 720-minute time point. In the late group, no definite trend was observed except for decreased CCL2 levels after ACTH administration. These changes may correlate with mechanisms underlying the anticonvulsant effects of ACTH.

In this study, the authors assessed cerebrospinal fluid cytokine levels and single-photon emission computed tomography (SPECT) findings in complex febrile seizures. This study included 23 Japanese patients with complex febrile seizures. Twenty patients underwent SPECT and 12 underwent analysis of cerebrospinal fluid cytokine levels (interleukin [IL]-6, interleukin-10, interleukin-17, interleukin-1ß, tumor necrosis factor-α, and interferon-γ); 9 patients underwent both studies. Cerebrospinal fluid cytokine levels were compared between the current complex febrile seizure patients and 30 patients with acute encephalopathy. In 17 of 20 patients, SPECT findings revealed areas of hypoperfusion, including the frontal (5), occipital (4), and lobular (4) regions, overlapping with other areas. Relative to patients with acute encephalopathy, those with complex febrile seizures exhibited significantly lower cerebrospinal fluid interleukin-6, interleukin-1ß, tumor necrosis factor-α, and interleukin-10 levels and significantly higher interleukin-17 levels. As patients with complex febrile seizures frequently exhibit abnormal SPECT findings, cerebrospinal fluid interleukin-17 levels might provide a valid biomarker to discriminate complex febrile seizures and acute encephalopathy, regardless of SPECT findings.
