Abstract Neuromyelitis optica is an autoimmune disorder characterized by optic neuritis, transverse myelitis, and aquaporin-4 autoantibodies.

Hypothermia, Hypotension, Hypersomnia, and Obesity Associated With Hypothalamic Lesions in a Patient Positive for the Anti-aquaporin 4 Antibody: A Case Report and Literature Review. Suzuki K, Nakamura T, Hashimoto K, Miyamoto M, Komagamine T, Nagashima T, Izawa N, Kanbayashi T, Takahashi T, Hirata K. Abstract OBJECTIVE To describe a patient positive for the anti-aquaporin 4 antibody with hypothalamic lesions showing hypothermia, hypotension, hypersomnia, and obesity.
A multi-institutional research team has found that rare variants in the gene coding an enzyme that controls the activity of a key immune cell occur more frequently in individuals with autoimmune disorders like rheumatoid arthritis and type 1 diabetes. Their report, which will appear in the journal Nature and is receiving early online release, identifies a pathway that could be a therapeutic target and may present a model for future investigations of the role of rare gene variants in common disorders.
Since the description of the association between neuromyelitis optica (Devic’s disease) and aquaporin 4 IgG antibody (NMO-IgG), the search for this antibody has been considered a highly recommended laboratory test when centromedullary multisegmental lesions are observed by magnetic resonance imaging (MRI). Such MRI lesions have not been confined to acute NMO because other infectious and post-infectious disorders may display a similar lesional pattern. However, NMO-IgG has not been currently searched and associated with these myelitides
Neuromyelitis optica (NMO) is an inflammatory demyelinating disorder characterized by optic neuritis and acute myelitis. A parainfectious pathogenesis may play a partial role in the development of this disorder.
Background: Macular star results from deposits of hard exsudate in Henle’s fiber layer radiating out in a starlike pattern in patients with infectious optic neuritis or neuroretinitis.
Recently, a disease-specific antibody was found in serum from patients with neuromyelitis optica (NMO), and its target antigen was identified as aquaporin 4 (AQP4) water channel protein. There is no clinical picture of pediatric cases with anti-AQP4 antibody, except one report from North America. Here, we report the clinical features of 18 Japanese anti-AQP4 antibody -positive patients with childhood-onset of NMO
Neuromyelitis optica is a central nervous system disease characterized by optic neuritis and transverse myelitis. It is a devastating illness, and early treatment may prevent future relapses and severe disability. However, there is much variability in protocols used for treatment.
INTRODUCTION: Optic neuromyelitis or Devic’s syndrome is a very rare disease affecting the optic tracts and the spinal cord. Its association with evolving pulmonary tuberculosis has been reported in a handful of case reports.
