INTRODUCTION: Neuromyelitis optica spectrum disorders (NMOSD) are more prevalent in adulthood, with few cases reported in pediatric age (<18 years). In this group, anti-aquaporin 4 (AQP4) antibodies are less frequent, while antibodies against myelin oligodendrocyte glycoprotein (MOG) are more commonly detectable than in adults.
OBJECTIVE AND METHODS: Description of pediatric NMOSD cases identified in a national multicentric NMOSD Portuguese registry.
RESULTS: Twenty (11.1%) NMOSD cases were diagnosed in pediatric age. Twelve (60%) were female, with a median age of onset of 12.5 (6.8-16.5) years. The presenting feature was transverse myelitis in 10 (50%), 4 of which with simultaneous optic neuritis and 2 with concomitant brainstem syndrome. Nine patients (45%) had pleocytosis in the CSF. Six (30.0%) exhibited anti-AQP4 antibodies, 13 (65.0%) anti-MOG antibodies, and one was seronegative for both. Four anti-AQP4 antibodies-positive patients had ≥1 relapse. Most anti-MOG-positive cases were monophasic (53.8%). In the acute phase, all patients received IV methylprednisolone, nine received IVIg and four plasma exchange. One anti-AQP4-positive patient died. Ten patients (5 anti-AQP4-positive/5 anti-MOG-positive) were on maintenance immunosuppressive therapy at the time of data collection.
CONCLUSION: NMOSD may present in pediatric age. It is essential to establish the diagnosis and promptly start therapy to improve the prognosis.
