Multiple sclerosis : clinical and laboratory research

Myelin oligodendrocyte glycoprotein (MOG) antibody disease is a rare autoimmune disorder with antibodies against the MOG predominantly involving the optic nerve and spinal cord leading to vision loss and paralysis. When MOG antibody disease involves the brain, the phenotype is similar to acute disseminated encephalomyelitis (ADEM). In this review, we discuss MOG-positive cases presenting with encephalitis, encephalopathy, or ADEM-like presentation based on recently published series.

Neurofilament light chain (NFL) and chitinase-3-like-1 (CHI3L1) concentrations in cerebrospinal fluid (CSF) may have prognostic value in clinically isolated syndromes (CIS) and relapsing-remitting multiple sclerosis (RRMS). ⋯ CSF concentrations of NFL are associated with 2-year relapse risk but not with disease progression or clinical worsening in newly diagnosed CIS and RRMS patients. This may be due to confounding by the effect of disease-modifying therapies.
