Neuromyelitis optica (NMO) and Neuromyelitis optica spectrum disorders (NMOSD) are a group of autoimmune conditions characterized by inflammatory involvement of the optic nerve, spinal cord and central nervous system. Novel evidence showed a key role of autoantibodies against aquaporin-4 immunoglobulin G (AQP4 IgG) in the pathogenesis of NMOSD and, recently, new classification and diagnostic criteria have been adopted to facilitate an earlier identification and improve the management of these conditions. Diagnosis of NMOSD is currently based on clinical, neuroimaging and laboratory features...

BACKGROUND Neuromyelitis optica (NMO) is a rare demyelinating disease of the central nervous system; NMO predominantly affects the spinal cord and optic nerves. The diagnosis is based on history, clinical presentation, seropositive NMO-IgG antibody, and notably, exclusion of other diseases. Despite the absence of definitive therapeutic strategies for NMO, methylprednisolone pulse therapy and plasma exchange are used for acute phase treatment, while immunosuppressive agent(s) are recommended to prevent relapses and improve prognosis...

Neuromyelitis optic spectrum disorders are demyelinating conditions that are typically idiopathic, though various case reports have demonstrated an association with malignancy. We present the case of a 64year old woman with NMOSD in the setting of small cell lung cancer. She had longitudinally extensive transverse myelitis and left eye optic neuritis; aquaporin-4 antibodies were elevated. Biopsy of mediastinal adenopathy was positive for SCLC. Malignancy should be considered in any patient with an atypical presentation of NMOSD, or who does not respond to traditional therapies...

We collected serum-cerebrospinal fluid (CSF)-paired samples during the acute phase of clinical episodes in MS and NMO patients, together with paired samples from non-MS/NMO patients, to compare the quotients of proteins and electrolytes among them. In NMO, the quotient of chloride was significantly higher in the acute phase of optic neuritis and brain lesions, but it was significantly lower in the acute phase of myelitis. Such findings were not observed in MS or in non-MS/NMO cases. With the coexistence of serum anti-AQP4-Ab, chloride imbalance between serum and CSF could be associated with the clinical episodes in NMO...

Importance: Myelin oligodendrocyte glycoprotein antibodies (MOG-Abs) are consistently identified in a range of demyelinating disorders in adults and children. Current therapeutic strategies are largely center specific, and no treatments have been formally evaluated. Objective: To examine the clinical phenotypes, treatment responses, and outcomes of children with relapsing MOG-Ab-associated disease. Design, Setting, and Participants: This study prospectively collected demographic, clinical, and radiologic data from 102 patients from 8 countries of the EU Paediatric Demyelinating Disease Consortium from January 1, 2014, through December 31, 2016...

Importance: Severe visual impairment is one of the major symptoms in neuromyelitis optica spectrum disorder (NMOSD), but functional network reorganization induced by the diminished sensory input has not been investigated thus far. Objective: To examine adaptive visual network connectivity changes in NMOSD. Design, Setting, and Participants: In this cross-sectional study, data were collected from May 1, 2013, through February 31, 2016, from 31 patients with aquaporin-4 antibody-positive NMOSD and 31 age- and sex-matched healthy control individuals at the Department of Neurology and NeuroCure Clinical Research Center at Charité-Universitätsmedizin Berlin, Berlin, Germany...

BACKGROUND: Neuromyelitis optica (NMO) is characterized by unpredictable attacks on the optic nerves and spinal cord, causing accumulations of neurological disability that may lead to blindness and paralysis. We examined comorbidities and health care use among patients with highly active NMO, defined as at least two relapses within 12months of the patient's first NMO encounter in the database. METHODS: This retrospective study of a US administrative claims database compared patients with highly active NMO to matched individuals without NMO...

BACKGROUND: There is a need for biomarkers that can classify optic neuritis (ON) attacks as belonging to either neuromyelitis optica spectrum disorder with optic neuritis (NMOSD-ON) or relapsing remitting multiple sclerosis with optic neuritis (MS-ON). This study uses spectral domain optical coherence tomography (SD-OCT) data to perform a preliminary contrast between NMOSD-ON and MS-ON by analyzing peripapillary retinal nerve fiber layer and intra-macular layer patterns of injury. METHODS: In this cross-sectional study, we used SD-OCT to obtain peripapillary retinal nerve fiber layer and intra-macular layer data for 26 NMOSD-ON, 25 MS-ON, and 26 healthy control (HC) age-matched eyes...

BACKGROUND: An increasing number of studies have investigated the value of optical coherence tomography in patients with neuromyelitis optica (NMO) spectrum disorders; however, no systematic review has been performed to date. We aimed to systematically review and investigate the possibility of differentiating NMO and multiple sclerosis (MS) via an optical coherence tomography measurement. METHODS: Electronic databases, including MEDLINE, EMBASE and Web of Science, were systematically searched up to June 2017...

Antibodies targeting myelin oligodendrocyte glycoprotein (MOG) have been recently reported in association with idiopathic inflammatory central nervous system disorders. Initially believed to be a benign disorder, anti MOG-IgG was noted to cause steroid responsive recurrent optic neuritis and isolated longitudinally extensive myelitis. However, there is growing evidence that the disease may be predominantly relapsing, often producing severe visual loss and involving regions other than the spinal cord and optic nerve...

BACKGROUND: Brain magnetic resonance imaging (BMRI) lesions were classically not reported in neuromyelitis optica (NMO). However, BMRI lesions are not uncommon in NMO spectrum disorder (NMOSD) patients. OBJECTIVE: To report BMRI characteristic abnormalities (location and configuration) in NMOSD patients at presentation. METHODS: Medical records and BMRI characteristics of 79 patients with NMOSD (during the first documented attack) in Argentina, Brazil and Venezuela were reviewed retrospectively...

We compared the retinal thickness in the unaffected eyes among the following subtypes of unilateral optic neuritis (ON): multiple sclerosis (MS-ON), neuromyelitis optica spectrum disorder with anti-AQP4 autoantibody (AQP4-ON), patients with serum anti-MOG antibody (MOG-ON), and idiopathic ON. In the chronic phase, macular GCC and circum-papillary RNFL in the unaffected eyes were both atrophied in MS-ON and AQP4-ON, but were not atrophied in the others. Titers of anti-AQP4-Ab was suggested to be associated with such latent neurodegenerative process in AQP4-ON...

Previous research indicated the association between hepatitis B virus (HBV) infection/vaccination and the onset of demyelinating diseases. However, most of these studies were single case reports, and comprehensive data are still scarce. Here we present a comprehensive analysis of 10 patients with neuromyelitis optica spectrum disorder (NMOSD) combined with chronic hepatitis B (CHB) infection and seropositive for anti-aquaporin-4 antibody (AQP4-Ab). Demographic, clinical, laboratory, neuroimaging, outcome, and follow-up data of the 10 patients were retrospectively analyzed...

In recent years, not only the incidence of brain demyelinating disease has increased, but also it seems that the world is facing new forms of autoimmune diseases of the brain. Distinguishing these diseases from each other is very important, since each requires a different treatment. The new criteria that were put forward in 2015 were meant to pave the way for better diagnosis of these diseases called neuromyelitis optica spectrum disease (NMOSD). However, too much emphasis on the criteria based on the convergence and association of radiological findings with the clinical symptoms actually causes confusion in the diagnosis...

Neuromyelitis Optica Spectrum Disorder (NMOSD) is a relapsing neuro inflammatory disease of the central nervous system that typically presents with optic neuritis or myelitis and may cause severe disability. The diagnostic criteria have been updated and several immunosuppressive agents have been demonstrated to prevent acute exacerbations. As the disease rarely develops in a progressive course, management of acute attacks and proper prevention of exacerbations may change the long term out-come and prevent future disability...

Neuromyelitis optica (NMO) and NMO spectrum disorder (NMOSD) is a rare relapsing autoimmune disease of the central nervous system constituting less than 1% of demyelinating diseases (Jeffery and Buncic, 1996). It preferentially affects the optic nerves and spinal cord, with the brain parenchyma generally spared. Demyelinating lesions are characterised by longitudinally extensive transverse myelitis (LETM) and often longitudinally extensive optic neuritis. Following the discovery of a novel pathogenic antibody, Aquaporin 4 in 2004 (Lennon et al...

The incidence of neuromyelitis optica spectrum disorders (NMOSD) in the Asian population is much higher than in Europe and North America. Optic neuritis is the first sign of NMOSD for some people. Identification of aquaporin 4 antibody is a milestone in the research of NMOSD and has been included in the diagnosis standard of NMOSD, but about 20% to 30% of NMOSD patients is aquaporin 4 antibody-negative. With the cell-based assays, oligodendrocyte glycoprotein antibodies in demyelinating diseases of the central nervous system have aroused the attention of researchers...

A condition associated with an autoantibody against MOG has been recently recognized as a new inflammatory disease of the central nervous system, but the disease course and disability outcomes are largely unknown. In this study we investigated clinical characteristics of MOG-antibody disease on a large cohort of patients from the UK. We obtained demographic and clinical data on 252 UK patients positive for serum immunoglobulin G1 MOG antibodies as tested by the Autoimmune Neurology Group in Oxford. Disability outcomes and disease course were analysed in more detail in a cohort followed in the Neuromyelitis Optica Oxford Service (n = 75), and this included an incident cohort who were diagnosed at disease onset (n = 44)...
