Background: Myelin oligodendrocyte glycoprotein (anti-MOG) antibody was reported in anti-aquaporin-4 (anti-AQP4) seronegative neuromyelitis optica spectrum disorders (NMOSD) patients. Objectives: To describe clinical phenotypes associated with anti-MOG. Methods: Seventy consecutive Thai patients with inflammatory idiopathic demyelinating central nervous system disorders (IIDCD) who were previously anti-AQP4 seronegative were tested for anti-MOG. Results: Anti-MOG was positive in six patients, representing 20.7% of the IIDCD anti-AQP4 seronegative patients with a non-multiple sclerosis phenotype, and most had relapses. All first presented with optic neuritis with good visual recovery after treatment. Conclusions: Anti-MOG positive patients may have manifestations that mimic NMOSD but differ in their course and prognosis from anti-AQP4 positive NMOSD.

Spectrum Disorders

Neuromyelitis optica (NMO), a chronic inflammatory, demyelinating autoimmune disorder of the central nervous system with a predilection for the optic nerves and spinal cord, has long been confused with classical multiple sclerosis. In this chapter, we review the important clinical and radiographic distinctions of NMO and NMO spectrum disorders, and summarize promising new concepts in pathophysiology and therapeutic approaches.

AbstractAcquired demyelinating syndromes (ADS) present with acute or subacute monofocal or polyfocal neurologic deficits localizing to the central nervous system. The clinical features of distinct ADS have been carefully characterized including optic neuritis, transverse myelitis, and acute disseminated encephalomyelitis. These disorders may all be monophasic disorders. Alternatively, optic neuritis, partial transverse myelitis, and acute disseminated encephalomyelitis may be first presentations of a relapsing or polyphasic neuroinflammatory disorder, such as multiple sclerosis or neuromyelitis optica. The clinical features of these disorders and the differential diagnosis are discussed in this article.

New Criteria

Background: The international panel for neuromyelitis optica (NMO) diagnosis has proposed diagnostic criteria for neuromyelitis optica spectrum disorders (NMOSD). Objectives: We assessed the impact of these criteria on diagnostic rates in a large cohort of patients. Methods: We identified and applied the 2006 and 2015 criteria to all patients ( n = 176) seen in the NMO and non-multiple sclerosis central nervous system demyelination clinic (part of the UK NMO service) from January 2013 to May 2015. Results: The 2006 criteria classified 63 of 176 (36%) patients as NMO. A total of 42 patients (67%) were aquaporin 4 (AQP4) immunoglobulin G (IgG) +ve and 21 (33%) AQP4 IgG −ve. The 2015 criteria classified 111 of 176 (63%) patients as NMOSD, of which 81 (73%) were AQP4 IgG +ve and 30 (27%) were AQP4 IgG −ve. There was an increase of 48 patients (76%) diagnosed as NMOSD using the new criteria. Conclusion: Application of the 2015 criteria led to a rise in diagnosis of NMOSD by 76%. The rise in the AQP4 IgG +ve group contributed 62% and the seronegative group contributed 14%.

The Central Nervous System

Neuromyelitis optica (NMO), or Devic’s disease is an inflammatory disorder of the central nervous system that preferentially affects the optic nerves and spinal cord. Initially considered a variant of multiple sclerosis (MS), NMO is now clearly recognized to have distinct clinical, radiographic, and pathologic characteristics. Historically, the diagnosis of NMO required bilateral optic neuritis and transverse myelitis; however, the identification of a specific biomarker, NMO-IgG, an autoantibody against the aquaporin-4 (AQP4) water channel, has broadened NMO spectrum disease to include patients with diverse clinical and radiographic presentations. This chapter addresses the diagnosis, pathophysiology, and management of the disease.

Spectrum Disorders

Neuromyelitis optica spectrum disorders (NMOSD) are inflammatory diseases of the central nervous system, traditionally diagnosed in patients with inflammatory attacks restricted to the optic nerves and spinal cord. The chapter considers the epidemiology, pathophysiology and immunopathogenesis of NMOSD. The clinical presentation and radiographic features are reviewed and the prognosis of patients with NMOSD is considered. The mortality and morbidity of untreated NMOSD is much greater than those of MS. Treatment options are summarized and finally future prospects of research are considered.

Relapsing Remitting Multiple Sclerosis

Background:Neuromyelitis optica (NMO) and multiple sclerosis (MS) are autoimmune diseases of the central nervous system with complex pathogeneses. NMO was once considered to be a severe variant of MS. There has been more evidence that a non-synonymous exchange (rs763361/Gly307Ser) in the gene for CD226 is linked to several autoimmune diseases including multiple sclerosis (MS). However, no studies have investigated the role of rs763361 in the pathogenesis of NMO.Objectives:The goal of our study is to evaluate the role of CD226 Gly307Ser in neuromyelitis optica (NMO) in Southern Han Chinese.Methods:Eight-nine NMO patients, 93 relapsing-remitting multiple sclerosis (RRMS) patients, and 122 controls (CTLs) were enrolled. The rs763361 alleles of the subjects were determined by sequencing-based typing.Results:The results strongly support that the TT genotypes are associated with NMO but are not significantly correlated with susceptibility for MS.Conclusions:CD226 Gly307Ser may correlate with risk of NMO in Southern Han Chinese.

AbstractMultiple sclerosis (MS) and neuromyelitis optica (NMO) are inflammatory demyelinating disorders of the central nervous system (CNS). Various genetic and environmental factors have been identified to contribute to etiology of MS and NMO. Aquaporin 4 (AQP4), is the most abundant water channel in CNS.

Neuromyelitis optica spectrum disorder (NMOSD) is an aggregate of inflammatory and autoimmune disorders of the central nervous system characterized by recurrent, disabling clinical course and damages predominantly targeting optic nerves, brain stem and spinal cord. NMOSD is stratified into two types: seropositive for aquaporin-4 antibodies (AQP4-IgG) and seronegative, which is reported in 25 % of cases. This article presents modern conceptualizations of NMOSD and describes authors’ own experience of clinical observation of patients.
