Here, we investigated the relationship between serum 25-hydroxyvitamin D3 (25[OH]D3) levels and neuromyelitis optica spectrum disorder (NMOSD). Patients with NMOSD had lower 25(OH)D3 levels than healthy people, with lower levels in patients in the acute phase than those in remission. An inverse correlation was found between 25(OH)D3 and Expanded Disability Status Scale scores of patients during attacks. Higher serum 25(OH)D3 levels were associated with greater amelioration of symptoms during corticosteroid therapy...

OBJECTIVE: Sjögren's syndrome (SS) patients may be affected by the neuromyelitis optica spectrum disorder (NMOSD), a severe demyelinating syndrome associated with anti-aquaporin 4 antibodies (anti-AQP4 antibodies). The relationship between SS and NMOSD has been a sustained focus of investigation. Among SS patients, anti-AQP4 antibodies have been detected exclusively in those with NMOSD. It has therefore been speculated that NMOSD is not a neurological complication of SS. However, such studies evaluated small numbers of SS patients, often admixed with other inflammatory disorders...

Monoclonal-antibody has been used for patients with autoimmune disorders for several years, and efficacy and safety were appreciated for these patients. Neuromyelitis optica specturm disorder (NMOSD) has been defined as an autoimmune demyelination disorder of the central nervous system (CNS) with a course of relapse-remission. Treatment of prevention is important for patients with NMOSD because of the increased disability after several attacks. Multiple factors were involved in the pathogenesis of NMOSD. Currently, targeting specific factor was favored in the research into the treatment for NMOSD...

BACKGROUND: Neuromyelitis optica spectrum disorder (NMOSD) patients may be at increased risk of venous thromboembolism (VTE) not only due to ambulatory disability but also due to systemic autoimmune and inflammatory mechanisms altering the hemostatic balance. OBJECTIVE: To compare the risk of VTE in NMOSD versus multiple sclerosis (MS) patients hospitalized for acute relapses. METHODS: Hospital admissions for MS or NMOSD exacerbations were retrospectively identified...

Importance: Neuromyelitis optica spectrum disorders (NMOSDs) are autoimmune astrocytopathies characterized by predominant involvement of the optic nerves and spinal cord. In most patients, an IgG autoantibody binding to astrocytic aquaporin 4, the principal water channel of the central nervous system, is detected. Rituximab, a chimeric monoclonal antibody specific for the CD20 B-lymphocyte surface antigen, has been increasingly adopted as a first-line off-label treatment for patients with NMOSDs...

INTRODUCTION: Recently defined consensus criteria for the diagnosis of neuromyelitis optica spectrum disorders (NMOSD) allow establishing the diagnosis in patients without elevated AQP4-Ab and optic nerve involvement. According to the new extended definition, NMOSD is closely associated with extensive spinal cord inflammation occurring in the course of systemic autoimmune diseases as sarcoidosis or lupus erythematodes. NMOSD occurring in the course of hematological disease have not yet been reported in the literature...

BACKGROUND: Multiple sclerosis (MS) and neuromyelitis optica spectrum disorder (NMOSD) are autoimmune inflammatory demyelinating diseases of the central nervous system. Although distinguished by clinicoradiological and demographic features, early manifestations can be similar complicating management. Antibodies against aquaporin-4 support the diagnosis of NMOSD but are negative in some patients. Therefore, there is unmet need for biomarkers that enable early diagnosis and disease-specific intervention...

Sudden hearing loss may occur in rare cases of relapsing-remitting multiple sclerosis (RRMS). There have also been reports of idiopathic sudden sensorineural hearing loss (SNHL) in patients with neuromyelitis optica spectrum disorders (NMOSD), but the frequency of such cases is unclear. We conducted a retrospective analysis of the medical records of 173 consecutive patients with multiple sclerosis (MS) and 101 consecutive patients with NMOSD who tested positive for anti-aquaporin-4 antibodies in addition to 37 consecutive patients with clinically isolated syndromes (CIS) to investigate the frequency and onset timing of SNHL...

The CD40 gene is associated with many autoimmune diseases; however, there are few studies in literatures that investigate the association between CD40 and neuromyelitis optica spectrum disorders (NMOSD). This study aimed to estimate the potential association of CD40 gene polymorphisms with susceptibility to NMOSD. Four SNPs (rs1883832, rs3765459, rs4810485, and rs6074022) were selected and genotyped in a Chinese cohort comprising 162 patients with NMOSD and 237 healthy controls. P values, odds ratios (ORs), and 95 % confidential intervals (CI) for four test models (allelic, additive, dominant, and recessive) were used to assess relationships between CD40 and NMOSD...

Neuromyelitis Optica Spectrum Disorders (NMOSD) are associated with autoantibodies (ABs) targeting the astrocytic aquaporin-4 water channels (AQP4-ABs). These ABs have a direct pathogenic role by initiating a variety of immunological and inflammatory processes in the course of disease. In a recently-established animal model, chronic intrathecal passive-transfer of immunoglobulin G from NMOSD patients (NMO-IgG), or of recombinant human AQP4-ABs (rAB-AQP4), provided evidence for complementary and immune-cell independent effects of AQP4-ABs...
