BACKGROUND: Neuromyelitis optica spectrum disorder (NMOSD) and multiple sclerosis (MS) are associated with reduced Health Related Quality of Life (HRQOL). To the best of our knowledge, change of HRQOL in patients with NMOSD has not been yet measure in Iran. The objective of this study was to assess HRQOL in NMOSD and MS patients and identify related factors METHODS: A cross sectional study of 41 patients with NMOSD and 136 age and sex-match MS patients was performed. A series of questionnaires including Persian validated questionnaires on HRQOL (SF-36), fatigue (MFIS), depression (BDI-II), anxiety (HAM-A) and sleep quality (PSQI) were record...

Neuromyelitis optica (NMO) is an autoimmune, inflammatory demyelinating disorder often leading to severe vision impairment and disability. The discovery of a diagnostic biomarker, the aquaporin-4 antibody (AQP4-IgG), transformed the clinical diagnosis and treatment of NMO and broadened the spectrum of disease [NMO spectrum disorders (NMOSD)]. Though the antibody is highly sensitive and specific to NMOSD, routine testing in patients with typical optic neuritis is considered controversial. This article will provide a brief review of NMOSD and highlight the pros and cons of routine testing in typical optic neuritis...

Over the past few years, new-generation cell-based assays have demonstrated a robust association of autoantibodies to full-length human myelin oligodendrocyte glycoprotein (MOG-IgG) with (mostly recurrent) optic neuritis, myelitis and brainstem encephalitis, as well as with acute disseminated encephalomyelitis (ADEM)-like presentations. Most experts now consider MOG-IgG-associated encephalomyelitis (MOG-EM) a disease entity in its own right, immunopathogenetically distinct from both classic multiple sclerosis (MS) and aquaporin-4 (AQP4)-IgG-positive neuromyelitis optica spectrum disorders (NMOSD)...

Hypothalamic involvement in multiple sclerosis (MS) and neuromyelitis optica spectrum disorder (NMOSD) is rare and endocrinopathies involving the hypothalamic-pituitary axis in patients with demyelinating conditions have rarely been reported. We present two cases of MS/NMOSD with associated hypothalamic-pituitary involvement and subsequent hypopituitarism, including the first report of a patient with hypothalamic demyelination causing panhypopituitarism. Differential diagnoses, including alemtuzumab-related and primary pituitary pathology are discussed...

BACKGROUND: Neuromyelitis optica spectrum disorder (NMOSD) is an inflammatory disease of the central nervous system. Although complement-dependent astrocyte damage mediated by anti-aquaporin 4 autoantibody (AQP4-Ab) is well acknowledged to be the core of NMOSD pathogenesis, additional inflammatory cascades may contribute to the establishment of lesion formation. Thus, in this study, we investigated the possible pathogenic role of immune-reactive mitochondrial DNA (mtDNA) in cerebrospinal fluid (CSF) of NMOSD patients...

BACKGROUND: Neuromyelitis optica (NMO) spectrum disorder (NMOSD) is a devastating autoimmune inflammatory disorder of the central nervous system, which can result in blindness or paralysis. Currently, there is a dire need for new treatment options in the clinic. Several case series have shown that mycophenolate mofetil (MMF) may be an effective treatment for NMOSD patients. The dosing of MMF in the treatment of NMOSD has been poorly studied. Therefore, we evaluated the efficacy, tolerability, influential factors and optimal dosage of MMF in Chinese patients with NMOSD...

REVIEW
C Alves Do Rego, N Collongues
The new diagnostic classification of neuromyelitis optica spectrum disorder (NMOSD) in 2015 highlights the central role of biomarkers, such as antibodies against aquaporin-4 (AQP4-Ab), in diagnosis. Also, in approximately 20-25% of patients without AQP4-Ab (NMOSDAQP4- ) the presence of an antibody directed against myelin oligodendrocyte glycoprotein (MOG) characterizes a specific population of NMOSD patients (NMOSDMOG+ ), according to their demographic and clinical data and prognoses. While double-seronegative cases (NMOSDNEG ) have not been fully described, they may correspond to the very first patients with opticospinal demyelination reported by Devic and Gault in 1894...

The pathogenesis in the exacerbation of neuromyelitis optica spectrum disorder (NMOSD) involves mainly the serum anti-aquaporin-4 (AQP4) immunoglobulin G antibody (anti-AQP4 antibody). If high-dose corticosteroid treatment is not achieved during remission, rescue plasmapheresis is recommended. However, there are few reports on the therapeutic efficacy of repetitive immunoadsorption plasmapheresis (IAPP) for the recurrent exacerbation of NMOSD with a fluctuating anti-AQP4 antibody level.

The diagnosis of multiple sclerosis (MS) and other demyelinating diseases of the central nervous system is challenging, and although the currently available biological and imaging tools offer considerable support to physicians, these tools often fail to provide a simple and final answer at the time of a first event. Thus, sets of diagnostic criteria have been published and tested on patient cohorts, and are now used in clinical trials and in daily clinical practice. These criteria have evolved over time to take into account physicians' and patients' needs, along with emerging paraclinical tests...

Antibodies against myelin oligodendrocyte glycoprotein (MOG-IgG) have been found in some cases diagnosed as seronegative neuromyelitis optica spectrum disorder (NMOSD). MOG-IgG allowed the identification of a subgroup with a clinical course distinct from that of NMOSD patients who are seropositive for aquaporin-4-IgG antibodies. MOG-IgG is associated with a wider clinical phenotype, not limited to NMOSD, with the majority of cases presenting with optic neuritis (ON), encephalitis with brain demyelinating lesions, and/or myelitis...

BACKGROUND: Encounter of autoantibodies with specific antigens can lead to hypersensitivity reactions and pathology. In multiple sclerosis and neuromyelitis optica spectrum disease (NMOSD), immunoglobulin-G (IgG) deposition has been observed in pathological lesions in the central nervous system. The paradigmatic autoantibodies in NMOSD are specific for the water channel aquaporin-4, localized to astrocytic end-feet at the blood-brain barrier and ependymal cells at the cerebrospinal fluid-brain barrier...

Antiphospholipid (aPL) antibodies have historically been postulated to cause a poorly understood inflammatory myelitis. Neuromyelitis optica spectrum disorder (NMOSD) causes an inflammatory longitudinally extensive transverse myelitis (LETM). In 2004, aquaporin-4 immunoglobulin G (AQP4-IgG) was first reported as a highly specific (>99%) serum diagnostic biomarker of NMOSD, distinguishing it from other disorders (eg, multiple sclerosis). We sought to assess the frequency of AQP4-IgG (and thus NMOSD diagnosis) in LETM with aPL antibodies...

Extensive research over the last decades basically failed to identify a common cause of noninfectious inflammatory central nervous system (CNS) demyelinating disease. To a great extent, this may reflect that the group of inflammatory CNS demyelinating disorders likely contains multiple pathogenetically distinct disease entities. Indeed, the greatest success so far in deciphering the pathogenesis of a CNS demyelinating disorder resulted from the discovery of anti-aquaporin (AQP)-4 antibodies (ab), which allowed progressive delineation of neuromyelitis optica (NMO), formerly considered a variant of the most common CNS demyelinating disorder, multiple sclerosis (MS), as a distinct disease...

Objective: To examine cases with a clinical course, signs, and symptoms mimicking MS, but without abnormalities on conventional MRI. Methods: Among 550 people with a tentative diagnosis of MS or neuromyelitis optica spectrum disorder (NMOSD), we selected patients, who met the 2010 McDonald diagnosis criteria for MS, but did not show abnormal findings on conventional brain and spinal cord MRI. After evaluating their clinical data, we analyzed fractional anisotropy (FA) values in the brain white matter on diffusion tensor MRIs and the frequencies of B-cell subsets in the peripheral blood in the corresponding cases as compared to healthy controls...
