Myelin oligodendrocyte glycoprotein and aquaporin-4 antibodies are highly specific in children with acquired demyelinating syndromes.
Our objectives were to evaluate the utility of measuring myelin oligodendrocyte glycoprotein (MOG) and aquaporin-4 (AQP4) antibodies (Ab) in clinical practice and describe their associated neurological phenotypes in children. ⋯ Myelin oligodendrocyte glycoprotein antibodies (MOG-Ab) are highly specific for acquired demyelinating syndromes (ADS). Myelin oligodendrocyte glycoprotein antibodies are not identified in children with peripheral demyelination or genetic leukodystrophies/hypomyelination. Up to 48% of MOG-Ab ADS paediatric patients relapse, higher than previously thought. Seroconversion to MOG-Ab negative status is infrequent; patients may test MOG-Ab positive at follow-up sampling even when asymptomatic. Myelin oligodendrocyte glycoprotein antibodies status should only be used in conjunction with the clinical information to guide maintenance therapy.
