Abstract

Background: Myelin-oligodendrocyte glycoprotein and aquaporin-4 have been extensively analyzed as targets for humoral immune reactions in central nervous system (CNS) demyelinating diseases, and the results indicated a possible role of these antibodies in the pathogenesis of various demyelinating diseases. Objective: To investigate the antibody titer levels against myelin-oligodendrocyte glycoprotein and aquaporin-4 in pediatric patients with inflammatory CNS disorders, and to evaluate clinical significance to study anti-myelin-oligodendrocyte glycoprotein antibodies. Methods: Sera at onset from patients with acute disseminated encephalomyelitis (ADEM) in 7, optic neuritis (ON) in 5, pediatric MS in 4 and neuromyelitis optica in one were tested for myelin-oligodendrocyte glycoprotein and aquaporin-4 antibodies using cell-based assays with live transfected cells. The duration of the observation periods ranged from 1 to 21. years (median, 10. years). We also described clinical course of patients with positive anti-myelin-oligodendrocyte glycoprotein antibodies. Results: Among 17 patients diagnosed with inflammatory CNS demyelinating diseases nine (52%) were positive to anti-myelin-oligodendrocyte glycoprotein antibodies. Of note, all cases with positive anti-myelin-oligodendrocyte glycoprotein antibodies showed seronegativity against anti-aquaporin-4 antibodies and had a favorable prognosis. Conclusions: This preliminary report showed that anti-myelin-oligodendrocyte glycoprotein antibodies testing at onset could be a useful tool predicting clinical outcome of children with ADEM, ON, and MS.
