Abstract: Neuromyelitis optica spectrum disorder is uncommon in children, and often seronegative for aquaporin-4 immunoglobulin G (AQP4-IgG). We conducted a retrospective study of 67 children presenting to a single Australian center with acquired demyelinating syndromes over a 7-year period. All patients were tested for AQP4-IgG. Five children (7.5%) had neuromyelitis optica spectrum disorder. One child was seropositive for AQP4-IgG (1.5%) and had a relapsing disease course with mild residual deficits. She also had a concomitant motor axonal neuropathy that improved with immunosuppressive therapy. Of the remaining 4 children, 3 had a monophasic course and 1 a relapsing course. Two were tested for anti-myelin oligodendrocyte glycoprotein (anti-MOG) antibody and both were seropositive. This study confirms that neuromyelitis optica spectrum disorder is uncommon in children, and that AQP4-IgG seropositivity is rare. Anti-MOG antibodies should be tested in children with neuromyelitis optica spectrum disorder.
