Abstract

Myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD) is diagnosed by serum MOG-immunoglobulin G (MOG-IgG) in association with typical demyelination. 111/1127 patients with paired CSF/serum samples were seropositive for MOG-IgG. Only 7/1016 (0.7%) seronegative patients had CSF-restricted MOG-IgG. While 3/7 patients had longitudinally extensive transverse myelitis, four had a confirmed alternate diagnosis (three multiple sclerosis, one CNS vasculitis). In a national referral setting, CSF-restricted MOG-IgG had a low sensitivity (2.63%, 95%CI 0.55–7.50%) and low positive predictive value (1.97%, 95%CI 0.45–8.13%). We strongly recommend serum as the preferred diagnostic biospecimen, and urge caution in the interpretation of CSF-restricted MOG-IgG in patients without clinico-radiological features consistent with MOGAD.
