OBJECTIVE: To test for hypothesized disease- and treatment-induced changes in cytokines and adhesion molecules in children with opsoclonus-myoclonus syndrome (OMS).
METHODS: Multiplex bead assay technology was used for simultaneous measurement of 34 soluble cytokines in cerebrospinal fluid (CSF) and serum. Soluble intercellular adhesion molecule-1 (sICAM-1) and vascular cell adhesion molecule-1 (sVCAM-1) were measured by ELISA. In total, there were 388 children (239 OMS, 114 controls, and 35 other inflammatory neurological disorders (OIND)).
RESULTS: In untreated OMS, mean CSF IL-6 was elevated 2.3-fold, but 67-fold in OIND, without significant differences in other CSF cytokines. Mean serum concentrations of sIL-2Ra (+50%) and CXCL1 (+70%) (p<0.0001) were also raised. CSF CCL5 was more often detected in untreated OMS than controls (p=0.005), as was serum CCL11 and IL-13 in treated OMS. Mean CSF CCL4 and IL-1Ra were selectively higher in IVIg-treated OMS (p≤0.0001). CSF sICAM-1 was elevated only in OIND (3.3-fold); serum sICAM-1 was higher in untreated OMS (+21%); and sVCAM-1 was not affected. No correlations with OMS severity or duration were identified.
CONCLUSIONS: Novel cytokine, cytokine antagonist, and soluble adhesion molecule abnormalities due to OMS or treatment were found. However, the normality of much of the data strengthens previous findings implicating B cell mechanisms.
