Abstract

Antibodies against neuronal surface antigens (NSA-ab) have been described in pediatric opsoclonus-myoclonus syndrome (OMS). We analyzed the presence of NSA-ab by flow cytometry and immunocytochemistry of live cerebellar granular neurons (CGN) in the serum of 25 adult patients with idiopathic (14) and paraneoplastic (11) OMS. Paraneoplastic, but not idiopathic, OMS sera showed a CGN surface binding by flow cytometry higher than that of controls (mean MFI (median fluorescence intensity): 29+/-6.9 vs. 20+/-5.8; p=0.001) but only one serum had a binding greater than three standard deviations of controls. OMS sera did not label live CGN by immunocytochemistry. Unlike pediatric OMS, NSA-ab were not detected in adult cases suggesting that the immunity to NSA in OMS is heterogeneous.
