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...

BACKGROUND: Therapeutic plasma exchange (TPE) is an extracorporeal blood purification technique that is designed to remove substances with a large molecular weight. The TPE procedure includes removal of antibodies, alloantibodies, immune complexes, monoclonal protein, toxins or cytokines, and involves the replenishment of a specific plasma factor. The aim of the study was to describe the clinical response to TPE in various neurological patients, and to assess the clinical response to this therapy...

Neuromyelitis optica is a rare, severe inflammatory demyelinating disease of the central nervous system, previously described as affecting only the optic nerve and spinal cord. Since the discovery of a highly specific autoantibody, anti-aquaporin-4, lesions are now recognized outside these regions. We report a man with severe, debilitating symptoms resulting from a symptomatic lesion within the diencephalon, manifesting with abnormal circadian rhythms, autonomic dysfunction, behavioral disturbance, and complex visual hallucinations...

BACKGROUND: In a minority of patients with neuromyelitis optica spectrum disorder (NMOSD) and aquaporin-4 antibodies (AQP4-IgG), the disease has a paraneoplastic origin. It is unknown whether these patients have distinctive clinical features. OBJECTIVE: To report the clinical features of a series of patients with paraneoplastic NMOSD and AQP4-IgG and to review previously reported cases. METHODS: Retrospective analysis of clinical records of 156 patients with NMOSD and AQP4-IgG and review of previously reported patients with paraneoplastic NMOSD and AQP4-IgG...

REVIEW
Satoru Oji, Kyoichi Nomura
In recent years, immunoadsorption has been increasingly recognized as an alternative to therapeutic plasma exchange and used for the treatment of neurological disorders such as Guillain-Barré syndrome, chronic inflammatory demyelinating polyneuropathy, myasthenia gravis, neuromyelitis optica spectrum disorders, and multiple sclerosis, as well as autoimmune encephalitis. Unlike therapeutic plasma exchange, which requires fluid replacement with a blood solution such as fresh frozen plasma or albumin, immunoadsorption is a blood purification technique that enables the selective removal of humoral factors from separated plasma through a high-affinity adsorbent with tryptophan or phenylalanine...

Monoclonal antibody therapy is a new treatment strategy for many types of diseases including cancers and autoimmune diseases, realizing a high efficacy and tolerability. In multiple sclerosis (MS) and neuromyelitis optica (NMO) spectrum disorders, several monoclonal antibodies have been suggested to decrease the incidence of clinical relapse and the disease activity. In MS, anti-α4 integrin (natalizumab), anti-CD52 (alemtuzumab), anti-CD25 (daclizumab) and anti-CD20 (ocrelizumab) have been shown to effectively reduce the relapses in randomized controlled trials and have been approved by the Food and Drug Administration...

BACKGROUND: Neuromyelitis optica (NMO) is an inflammatory demyelinating central nervous system disease, with recurrent attacks of severe bilateral optic neuritis and longitudinally extensive transverse myelitis. Aggressive immunosuppression is essential to prevent clinical relapses and permanent disability. Rituximab, a monoclonal antibody to CD20, has been found effective in several reports and small uncontrolled studies. There is a paucity of data regarding its use in Indian patients...

The objective is to assess the frequency of AQP4-Ab in Chinese patients with optic neuritis (ON) and to investigate the prognostic implications of AQP4-Ab seropositivity in such patients. The presence of aquaporin-4 (AQP4) antibodies in human AQP4-transfected cells was determined by indirect immunofluorescence, and the diagnostic and prognostic relevance of AQP4 antibodies in 215 Chinese patients with optic neuritis was evaluated. The patients were enrolled from the Chinese People's Liberation Army General Hospital (PLAGH) and followed up to 1-228 months...

While it is recognized that aquaporin-4 (AQP4)-specific T cells and antibodies participate in the pathogenesis of neuromyelitis optica (NMO), a human central nervous system (CNS) autoimmune demyelinating disease, creation of an AQP4-targeted model with both clinical and histologic manifestations of CNS autoimmunity has proven challenging. Immunization of wild-type (WT) mice with AQP4 peptides elicited T cell proliferation, although those T cells could not transfer disease to naïve recipient mice. Recently, two novel AQP4 T cell epitopes, peptide (p) 135-153 and p201-220, were identified when studying immune responses to AQP4 in AQP4-deficient (AQP4(-/-)) mice, suggesting T cell reactivity to these epitopes is normally controlled by thymic negative selection...

Neuroinflammatory diseases such as multiple sclerosis, neuromyelitis optica, chronic inflammatory demyelinating polyneuropathy and myasthenia gravis are leading causes of physical disability in people of working age. In the last decades significant therapeutic advances have been made that can ameliorate the disease course. Nevertheless, many affected will continue to deteriorate despite treatment, and the costs associated with disease-modifying drugs constitute a significant fiscal burden on healthcare in developed countries...

Neuromyelitis optica is an autoimmune demyelinating inflammatory disease characterized by optic neuritis and myelitis with anti-aquaporin 4 antibodies. Hemophagocytic lymphohistiocytosis is a severe systemic inflammatory syndrome that can present in a genetic primary form or secondarily to infective, neoplastic or autoimmune diseases. Our case discusses the first reported case of atypical late-onset hemophagocytic lymphohistiocytosis in a patient with neuromyelitis optica, with multiple triggering factors and carrying the common A91V hypomorphic perforin mutation, that blurs the distinction between primary and secondary forms...

Brain abnormalities have frequently been reported in neuromyelitis optica (NMO) patients, but corticospinal tract involvement has rarely been described. Here we review the case of a 56-year-old woman who presented with unusual MRI features involving the whole corticospinal tract, and summarize the clinical features, neuroimaging, and prognosis of the case. The patient presented with bilateral visual loss and developed progressive weakness in both lower limbs, and urinary incontinence 12days later. Brain MRI revealed T2-hyperintensities in the bilateral corticospinal tract (posterior limb of the internal capsule and cerebral peduncle), callosal lesions, and subcortical white matter lesions...

BACKGROUND: Debate exists about whether neuromyelitis optica spectrum disorder seronegative disease represents the same immune-mediated attack on astrocytic aquaporin-4 as in seropositive disease. OBJECTIVE: We investigated whether response to common treatments for neuromyelitis optica spectrum disorder differed by serostatus, as assessed by change in annualized relapse rate. METHODS: We performed a multicenter retrospective analysis of 245 patients with neuromyelitis optica spectrum disorder who were treated with either rituximab or mycophenolate mofetil as their first-line immunosuppressive treatment for disease prevention...
