Abstract
BACKGROUND
Some pediatric patients with inflammatory demyelinating central nervous system disorders cannot be classified under any of the established disease entities, making their treatment and prognosis difficult.
OBJECTIVE
The objective of this study is to characterize a subgroup of pediatric patients with recurrent demyelinating central nervous system disorders.
METHODS
This study includes a case series of pediatric patients with monophasic or recurrent acute disseminated encephalomyelitis (ADEM) who later presented with either monophasic or recurrent optic neuritis (ON).
RESULTS
We describe seven patients with a median follow-up of six years (five females, two males) who presented at a median age of 6 years (range 4-8 years) with monophasic (n = 4) or recurrent ADEM (two to four attacks) followed by monophasic (n = 3) or recurrent ON (two to nine attacks). Cranial magnetic resonance imaging (MRI) was typical for ADEM (n = 6) with complete or almost complete resolution of lesions on follow-up. Cerebrospinal (CSF) studies at the time of ADEM showed a pleocytosis in six patients and were negative for oligoclonal bands (OCBs) in all. In all patients high titers for serum anti-MOG antibodies were detected.
CONCLUSION
ADEM followed by ON is a rare but distinct clinical phenotype among pediatric patients. Further studies are needed to allow recommendations on treatment or prognosis.
