OBJECTIVE To describe the clinical profile of demyelinating optic neuritis in African Americans. METHODS The medical records of all patients with a diagnosis of optic neuritis examined at the Neuro-Ophthalmology Unit at the Emory University Eye Center (Emory) and at the Grady Memorial Hospital Eye Clinic (Grady), Atlanta, Ga, between 1989 and 1996 were retrospectively reviewed. PATIENTS Afr...
neuromyelitis optica is an inflammatory demyelinating disease (idd) of the cns, which mainly affects optic nerve and spinal cord. autoantibodies against aquaporin-4 also known as nmo-igg have been implicated in the pathogenesis of nmo. we evaluated the sensitivity and specificity of nmo-igg assay for diagnosing nmo patients and differentiating them from ms patients and those with undifferentiat...
OBJECTIVE To evaluate clinical features among patients with neuromyelitis optica spectrum disorders (NMOSD) who have myelin oligodendrocyte glycoprotein (MOG) antibodies, aquaporin-4 (AQP4) antibodies, or seronegativity for both antibodies. METHODS Sera from patients diagnosed with NMOSD in 1 of 3 centers (2 sites in Brazil and 1 site in Japan) were tested for MOG and AQP4 antibodies using ce...
IMPORTANCE In patients with isolated optic neuritis (ON), the presence of antibodies to aquaporin 4 (AQP4) has diagnostic and prognostic value. In the same clinical setting, the significance of antibodies to myelin-oligodendrocyte glycoprotein (MOG) or the glycine receptor α1 subunit (GlyR) is unclear. OBJECTIVES To investigate the frequency of antibodies to AQP4, MOG, and GlyR in patients wi...
Neuromyelitis optica (NMO) is an inflammatory disease characterized by recurrent attacks of optic neuritis and myelitis. It is generally accepted that autoantibodies against aquaporin 4 water channel protein play a pathogenic role in neuromyelitis optica. We have recently reported that plasmablasts are increased in the peripheral blood of this autoimmune disease, and are capable of producing au...
OBJECTIVE To analyze the clinical, neuroimaging characteristics and positivity of the acquaporin water channel (NMO-IgG) in pediatric patients with neuromyelitis optica (NMO). This disorder could have a variable clinical expression. To address such variability, the term NMO spectrum has been suggested. METHOD We evaluated six pediatric patients, with a median age of 11 years at the time of th...
