Abstract
Devic's disease, also known as neuromyelitis optica (NMO), is an uncommon autoimmune condition that affects the optic nerves and spinal cord. It is characterized by recurrent optic neuritis and myelitis, which can cause paralysis and visual impairment. Because NMO mimics multiple sclerosis, diagnosing it is difficult and necessitates particular testing, such as magnetic resonance imaging (MRI) and aquaporin-4 antibody detection. Patients with NMOs are susceptible to severe, erratic episodes that can result in rapid impairment. As such, timely and efficient therapy with immunosuppressive medicines and continued supportive care are crucial. Improving mobility, strength, coordination, and quality of life while treating the functional deficiencies associated with NMOs requires the use of physiotherapy. This case study emphasizes how crucial it is to manage a young NMO patient using a multidisciplinary strategy in order to maximise results. This case report discusses a 16-year-old male presenting with a sudden onset of balance impairment, slurred speech, difficulty walking and breathing, and weakness in limbs, with the right side more affected. Over three months, he experienced increasing eyesight issues, fatigue, tremors during activities of daily living, difficulty swallowing, and night cramps. Diagnostic investigations including MRI, angiography, visual evoked potentials (VEP) study, and cerebrospinal fluid (CSF) analysis confirmed demyelinating changes consistent with NMO, also known as Devic's disease. The patient received management with steroidal medications, immunosuppressants, and plasma therapy, along with physiotherapy rehabilitation. The physiotherapy protocol aimed to address muscle weakness, coordination impairment, balance issues, fine motor deficits, fatigue, sensory impairment, and dependence on activities of daily living. Motor, sensory, and cranial nerve assessments were conducted, revealing impairments consistent with NMO. Outcome measures pre- and post-intervention showed improvements in functional independence, balance, and fatigue severity. The medical management included a combination of medications and investigations to manage NMO symptoms and monitor disease progression. The physiotherapeutic approach employed a multidisciplinary strategy focusing on education, exercise, and functional tasks to improve the patient's quality of life and independence.

Abstract
Neuromyelitis optica spectrum disorders (NMOSD) are rare, debilitating autoimmune diseases of the central nervous system. Many NMOSD patients have antibodies to Aquaporin-4 (AQP4). Prior studies show associations of NMOSD with individual Human Leukocyte Antigen (HLA) alleles and with mutations in the complement pathway and potassium channels. HLA allele associations with NMOSD are inconsistent between populations, suggesting complex relationships between the identified alleles and risk of disease. We used a retrospective case-control approach to identify contributing genetic variants in patients who met the diagnostic criteria for NMOSD and their unaffected family members. Potentially deleterious variants identified in NMOSD patients were compared to members of their families who do not have the disease and to existing databases of human genetic variation. HLA sequences from patients from Belgrade, Serbia, were compared to the frequency of HLA haplotypes in the general population in Belgrade. We analyzed exome sequencing on 40 NMOSD patients and identified rare inherited variants in the complement pathway and potassium channel genes. Haplotype analysis further detected two haplotypes, HLA-A*01, B*08, DRB1*03 and HLA-A*01, B*08, C*07, DRB1*03, DQB1*02, which were more prevalent in NMOSD patients than in unaffected individuals. In silico modeling indicates that HLA molecules within these haplotypes are predicted to bind AQP4 at several sites, potentially contributing to the development of autoimmunity. Our results point to possible autoimmune and neurodegenerative mechanisms that cause NMOSD, and can be used to investigate potential NMOSD drug targets.

Abstract
In this study, we included 461 NMOSD patients at our hospital from January 2016 to June 2019 and got some results. Eight (1.9%) originally AQP4-IgG-seronegative patients were retested as seropositive. 221 patients (47.9%) did not receive immunosuppressive treatment within 3 month. The adult/child distribution was significantly different (p = 0.001). Thirty-three patients (7.2%) had relapses after drug withdrawal, and fifteen of them had used drugs ≥3 years. The conclusion is that decision to treat with immunosuppression was made less often in children than in adults. Patients who took medication for a long time still need to be cautious of stopping using immunosuppression.

Abstract
Background Neuromyelitis optica spectrum disorder (NMOSD) is a rare neuroinflammatory disorder of the central nervous system that typically involves the optic nerve, the spinal cord and other specific brain regions. In relapse of the disease, factors associated with clinical features and lesion severity are important for clinicians to predict disease-related disability. Methods We retrospectively analyzed 22 female patients with NMOSD who had spinal cord lesions. Detailed clinical features, onset symptoms, motor disability, relapse episodes, serum aquaporin-4 (AQP4) and myelin oligodendrocyte glycoprotein (MOG) autoantibodies and MRI characteristics were documented to correlate their associations with the nadir and three-month Expanded Disability Status Scale (EDSS) scores. Patients with three-month EDSS scores below four (< 4) were categorized as the good outcome group, while those with scores of four or more (> 4) were categorized as the poor outcome group. Results In patients with NMOSD, the mean age was 44.5 ± 12.8 years, and the mean three-month EDSS score was 4.3 ± 1.9. A significantly higher all-limb muscle power score was found in the good EDSS group than in the poor EDSS group (p = 0.01). A tendency toward longer follow-up periods and lower anti-AQP4 antibody levels was found in the good outcome group. Serum anti-AQP4 antibodies were present in 86% of patients with NMOSD, and MOG autoantibodies were found in one anti-AQP4 antibody-negative patient (33.3%). In patients with NMOSD, more than 40% of spinal cord lesions were distributed at the middle cervical and upper thoracic levels. Conclusions Our findings suggest that EDSS scores and MRC scores at the nadir had significant associations with three-month EDSS scores. The topographic distributions of the spinal cord lesions might relate to different serum anti-AQP4 antibody status. However, further studies will be needed to corroborate this finding.

Abstract
Autoimmune responses to aquaporin 4 (AQP4) cause neuromyelitis optica (NMO); thus, specific immunotolerance to this self-antigen could represent a new NMO treatment. We generated the liposome-encapsulated AQP4 peptide 201-220 (p201-220) to induce immunotolerance. Liposomes were generated using phosphatidylserine and the polyglycidol species PG8MG. The in vivo tissue distribution of the liposomes was tested using an ex vivo imaging system. To confirm the antigen presentation capacity of PG8MG liposomes, dendritic cells were treated with PG8MG liposome-encapsulated AQP4 p201-220 (AQP4-PG8MG liposomes). Immunotolerance induction by AQP4-PG8MG liposomes was evaluated using the ex vivo cell proliferation of lymph node cells isolated from AQP4 p201-220-immunized AQP4-deficient mice. Fluorescent dye-labeled PG8MG liposomes were distributed to the lymph nodes. AQP4 p201-220 was presented on dendritic cells. AQP4-PG8MG liposomes were tended to suppress immune responses to AQP4 p201-220. Thus, the encapsulation of AQP4 peptides in PG8MG liposomes represents a new strategy for suppressing autoimmune responses to AQP4.

Abstract
Neuromyelitis optica is an inflammatory disorder of the central nervous system. It involves the immune-mediated demyelination of predominantly the optic nerves and the spinal cord, which can lead to optic neuritis and transverse myelitis, respectively. Patients usually present with symptoms related to the eyes or the spinal cord, like loss of vision, pain in the eyes, visual field defects or numbness and weakness of limbs. Vomiting and hiccups are common cases encountered in medicine clinics and can sometimes be an atypical presentation of this disorder. Here we present a case of a 33-year-old female who initially presented to our tertiary care centre with repeated episodes of bilious vomiting and intractable hiccups for 10 days. After multiple investigations over a couple of days, the patient was found to be positive for anti-NMO antibodies and displayed neuro-radiological findings on MRI brain and spine, which finally led to the diagnosis of neuromyelitis optica spectrum disorder (NMOSD). Through this case we highlight the importance of suspecting NMO in a patient with complaints of intractable vomiting and hiccups, so that early intervention and treatment can prevent further disabling complications of the disease.

Abstract
Objective To evaluate the long-term effects of rituximab (RTX) on total and specific immunoglobulins (Igs) in patients with neuromyelitis optica spectrum disorders (NMOSDs). Methods Total IgG, IgA, and IgM levels were evaluated in 15 patients with NMOSDs treated with RTX (median follow-up 70 months). Anti-aquaporin 4 (AQP4)-IgG titration was performed on samples from 9 positive patients. Anti-tetanus (TET), anti-varicella-zoster virus (VZV), and anti-Epstein–Barr virus nuclear antigen (EBNA) IgGs were also tested in patients with NMOSDs and in 6 healthy controls (HCs). Results RTX reduced total IgG by 0.42 g/L per year, IgA by 0.08 g/L per year, and IgM by 0.07 g/L per year. Hypogammaglobulinemia (hypo-IgG) (IgG < 7 g/L) developed in 11/15 patients. Severe hypo-IgG (IgG < 4 g/L) was found in 3/15 patients, of whom 2 patients developed serious infectious complications. In group analysis, anti-AQP4 IgG titers were reduced by RTX over time, and a significant correlation between anti-AQP4 IgG titers and total IgG levels was found. The effects of RTX were observed on pathogen-specific IgGs as well. In particular, the levels of anti-TET IgG in patients were significantly lower than those in HCs. The half-life of anti-TET IgG was reduced by about 50% in patients compared with the general population. Conclusions Long-term RTX treatment is associated with the risk of hypo-Ig and reduction of anti-TET protection in patients with NMOSDs. Results obtained in this study suggest the importance of monitoring total and specific Ig levels before and during treatment with anti-CD20 drugs to prevent hypo-Ig–related complications and to optimize clinical management.

Severe disease exacerbation in a patient with neuromyelitis optica spectrum disorder during treatment with dimethyl fumarate. Mult Scler Relat Disord 2018; 26:204-206. [PMID: 30268042 DOI: 10.1016/j.msard.2018.09.011] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/21/2018] [Revised: 08/21/2018] [Accepted: 09/11/2018] [Indexed: 11/24/2022]
Abstract
BACKGROUND Certain disease-modifying drugs for multiple sclerosis are known to be ineffective in treating neuromyelitis optica spectrum disorder (NMOSD), and can even induce subsequent relapses. CASE PRESENTATION Here, we report on a patient with NMOSD who was misdiagnosed with multiple sclerosis and experienced severe exacerbations 3 months following initiation of treatment with dimethyl fumarate. The patient developed severe relapse in the form of myelitis extending from the medulla down to the T1 vertebral level. Cord swelling seen as contrast enhancement on magnetic resonance imaging was observed. This swelling resulted in spastic hemiplegia with severe painful dysesthesia. After a diagnosis of NMOSD was confirmed, dimethyl fumarate was discontinued and treatment with azathioprine was initiated. Subsequently, although her neurological status stabilized, residual deficits persisted. CONCLUSION The case described here suggests that dimethyl fumarate is unsuitable for NMOSD treatment as it may cause disease exacerbations.

Abstract
This case describes an 81-year-old woman with a history of Sjögren's syndrome presenting with recurrent falls and poor balance. She subsequently developed new and rapidly evolving neurology including hyperaesthesia, spastic paraplegia and sphincteric dysfunction. Following serial clinical reviews and detailed investigations, MRI (brainstem and cervicothoracic spine) and a seropositive result for aquaporin 4 IgG, a diagnosis of neuromyelitis optica spectrum disorder (NMOSD) was made. This case describes the clinical course of this index patient with an unusual late age of onset. The report also includes a discussion on NMOSD. We review aspects of terminology, brief epidemiology, pathogenesis, notable autoimmune associations, variance in clinical presentation and current diagnostic criteria. We also review the importance of distinguishing NMOSD from multiple sclerosis in view of the significant implications for treatment and prognosis.

Abstract
Leber Hereditary Optic Neuropathy is an inherited optic neuropathy caused by mitochondrial DNA point mutations leading to sudden, painless loss of vision. We report a case of an 8-year-old boy presenting with a radiological phenotype of longitudinally extensive transverse myelitis on a background of severe visual impairment secondary to Leber Hereditary Optic Neuropathy (LHON). He was found to have dual mitochondrial DNA mutations at 14484 (MTND6 gene) and 4160 (MTND1 gene) in a family with a severe form of LHON characterised by not only an unusually high penetrance of optic neuropathy, but also severe extra-ocular neurological complications. The m.14484T>C mutation is a common LHON mutation, but the m.4160T>C mutation is to our knowledge not reported outside this family and appears to drive the neurological manifestations. To our knowledge there have been no previous reports of spinal cord lesions in children with LHON.

Abstract
Fingolimod (FTY) is the first oral medication approved for treatment of relapsing–remitting multiple sclerosis (RRMS). Its effectiveness and safety were confirmed in several phase III clinical trials, but proper evaluation of safety in the real patient population requires long‐term post‐marketing monitoring. Since the approval of FTY for RRMS in Japan in 2011, it has been administered to approximately 5000 MS patients, and there have been side‐effect reports from 1750 patients. Major events included infectious diseases, hepatobiliary disorders, nervous system disorders and cardiac disorders. In the present review, we focus especially on central nervous system adverse events. The topics covered are: (i) clinical utility of FTY; (ii) safety profile; (iii) post‐marketing adverse events in Japan; (iv) white matter (tumefactive) lesions; (v) rebound after FTY withdrawal; (vi) relationship between FTY and progressive multifocal leukoencephalopathy; (vii) FTY and progressive multifocal leukoencephalopathy‐related immune reconstitution inflammatory syndrome; and (viii) neuromyelitis optica and leukoencephalopathy.
