Abstract

Oligoclonal bands in cerebrospinal fluid reflect local B-cell responses associated with various neuroinflammatory disorders. In opsoclonus-myoclonus syndrome, cerebrospinal fluid B-cell expansion was demonstrated, but no studies of oligoclonal bands are available. In a prospective case-control study of 132 children (103 with opsoclonus-myoclonus, 29 neurologic control subjects), cerebrospinal fluid oligoclonal bands, measured by isoelectric focusing with immunofixation, were observed in 35% with opsoclonus-myoclonus and none of the control subjects, with the highest frequency in severe cases (56%). In oligoclonal band-positive patients, the mean band number was 5 ± 3 S.D. (range, 2-10) and the total severity score was significantly higher than in band-negative patients, whereas the frequency of CD19+ B cells, opsoclonus-myoclonus duration, neuroblastoma detection, and relapse history did not differ. The cerebrospinal fluid immunoglobulin G synthesis rate, immunoglobulin index, and Q albumin were normal. In 17 untreated children receiving adrenocorticotropic hormone, intravenous immunoglobulins, and rituximab, the number of oligoclonal band-positive decreased by 75%, and the mean band count fell by 80%. Oligoclonal band detection adds useful information to neuroimmunologic "staging" in opsoclonus-myoclonus. However, flow cytometry provides a more sensitive measure of B-cell infiltration. Cerebrospinal fluid oligoclonal bands warrant monitoring in long-term follow-up studies of disease-modifying drugs for opsoclonus-myoclonus.
