Objective: To elucidate the pathophysiology of West syndrome and mechanism of immunoglobulin therapy for this syndrome, we investigated serum and cerebrospinal fluid (CSF) cytokine levels before and after high-dose intravenous immunoglobulin (IVIG) therapy in patients with West syndrome. Methods: We measured serum and CSF cytokine levels of 11 patients with West syndrome who was referred to Saitama Children’s Medical Center from April 2010 to May 2014. All patients received IVIG, ranging from 200 to 500 mg/kg/day for 3 consecutive days (initial IVIG treatment), before adrenocorticotrophic hormone therapy. ⋯ Before IVIG treatment, the level of IL-8 in CSF was significantly higher than that in serum, while the serum IL-18 level in the seizure-free group was significantly lower than that in the seizure-persisting group. Alterations of serum IL-18 level and CSF IL-8 level were different between the seizure-free and seizure-persisting groups. Conclusions: Serum IL-18 and CSF IL-8 may be important factors for elucidating the pathophysiology of West syndrome and mechanism of IVIG therapy.
