Seropositivity for MOG-IgG in the setting of a severe relapse of central nervous system demyelination warrants aggressive therapy with intravenous methylprednisolone or plasmapheresis. Seropositivity for MOG-IgG in NMOSD-like disorders, including optic neuritis, transverse myelitis, and acute disseminated encephalomyelitis, predicts relapse and warrants consideration for maintenance immunosuppression. MS therapies may worsen MOG-IgG associated IDD, so correct diagnosis is important. Detection of MOG-IgG implies an inflammatory demyelinating disorder distinct from MS. Patients seropositive for MOG-IgG are commonly misdiagnosed as MS. There is currently no biomarker specific for MS (multiple sclerosis). Patients only rarely harbor both antibodies. Seropositivity predicts a relapsing phenotype and warrants immunosuppressive therapy. ![]() Of the remaining 20%, one-third harbor MOG-IgG. Neurological update: MOG antibody disease.Myelin oligodendrocyte glycoprotein (MOG)-IgG with neuromyelitis optica (NMO) spectrum disorder (SD)-like phenotype is now recognized as a sensitive and specific diagnostic antibody biomarker of inflammatory demyelinating disorders (IDD).Īpproximately 80% of patients fulfilling 2006 Wingerchuk criteria for NMO are seropositive for aquaporin-4 (AQP4)-IgG. ![]() MOG antibody demyelination: Information for patients.Emerging drugs for the treatment of adult MOG-IgG-associated diseases.

Transverse myelitis is when inflammation affects the spinal cord. eye pain, particularly when moving your eye. ![]() This nerve transmits signals between your eyes and your brain. Optic neuritis is inflammation of the optic nerve. It’s been associated with the following conditions: Optic neuritis MOGAD can affect parts of the nervous system like the optic nerve, spinal cord, and brain.
