Introduction: Stress fractures are more common in the weight-bearing bones of the lower limb and are particularly prevalent in athletes. Whereas, those of the upper limb are usually reported as unique events in rare circumstances. Case Report: We present a case of a 40-year-old White British female with neuromyelitis optica (NMO) who mobilized in a wheelchair and presented to our center in April 2016 with a week-long history of a hot, swollen, and unstable right forearm...

Objective: To understand, through an analysis of health insurance claims data, the current treatment status and medical cost of multiple sclerosis (MS) in Japan. Methods: We analyzed claims data (January 2005-January 2016) from the Japan Medical Data Center Co., Ltd., identifying MS patients, except those with neuromyelitis optica, using an algorithm based on diagnosis codes. Prescription drug usage and medical costs for MS patients were analyzed. Results: A total of 713 MS patients were identified in the database...

Vitamin D research has gained increased attention in recent times due to its roles beyond bone health and calcium homeostasis, such as immunomodulation. In some parts of the brain and on immune cells, vitamin D hydroxylating enzymes and its receptors are located. Epidemiological evidence demonstrates that deficiency of Vitamin D is relevant for disease risk and course in multiple sclerosis (MS) and presumably also in neuromyelitis optica spectrum disorders (NMOSD), Parkinson's disease (PD), and Alzheimer's disease (AD)...

The overlapping clinical features of relapsing remitting multiple sclerosis (RRMS), aquaporin-4 (AQP4)-antibody (Ab) neuromyelitis optica spectrum disorder (NMOSD), and myelin oligodendrocyte glycoprotein (MOG)-Ab disease mean that detection of disease specific serum antibodies is the gold standard in diagnostics. However, antibody levels are not prognostic and may become undetectable after treatment or during remission. Therefore, there is still a need to discover antibody-independent biomarkers. We sought to discover whether plasma metabolic profiling could provide biomarkers of these three diseases and explore if the metabolic differences are independent of antibody titre...

Background: Neurofilament light chain (NF-L) levels reflect axonal damage in different conditions, including demyelinating disorders. Objectives: We aimed to compare serum NF-L levels in patients with aquaporin-4 antibodies (AQP4-Ab), myelin oligodendrocyte antibodies (MOG-Ab) and seronegative cases with neuromyelitis optica spectrum disorders and related disorders. Methods: We analysed AQP4-Ab and MOG-Ab with cell-based assay and NF-L with ultrasensitive electrochemiluminescence immunoassay...

Background: A specific humoral immune response against HERV-W envelope surface (env-su) glycoprotein antigens has been reported in serum of patients with multiple sclerosis (MS). However, it has not been evaluated to date in patients with neuromyelitis optica spectrum disorder (NMOSD). Objective: The objective of this paper is to investigate whether antibody (Ab) response against HERV-W env-su antigenic peptides differs between NMOSD and MS. Methods: Serum samples were collected from 36 patients with NMOSD, 36 patients with MS and 36 healthy control individuals (HCs)...

Longitudinally extensive transverse myelitis (LETM) is defined as an inflammatory lesion of the spinal cord that extends to three or more segments. LETM is a commonly characteristic feature of neuromyelitis optica (NMO) or various autoimmune diseases. Manifestation of Mycobacterium tuberculosis (MTB) infection with LETM are rare and usually in the cervicothoracic spinal cord. Our patient presented with holocord LETM, so NMO was considered initially diagnosis. After in further research, MTB was diagnosed and treated successfully...

Background: Our group has used deep sequencing to identify viral RNA signatures in human brain specimens. We have previously used this method to detect HSV1, GBV-C, and measles virus sequence in brain tissue from deceased donors. Deep sequencing was performed on brain specimens from a cohort of patients who died with progressive forms of MS, revealing evidence of increased expression of some human endogenous retrovirus (HERV) domains. Objectives: Identify RNA sequences and new antigens involved in the pathogenesis of MS...

Microbial infections lead to neurological damages either by direct infection in the nervous tissues or by uncontrolled immune responses (immunopathology). For example, in Zika virus infection, microcephaly can be caused by the former, i.e., direct viral infection in the brain, while Guillain-Barré syndrome (GBS) seems to be antibody-mediated immunopathology. Although a variety of factors affect immunopathology, two essential systems maintaining whole-body homeostasis had long been neglected: 1) the lymphatic system and 2) microbiota...

AIM OF THE STUDY: Thiopurines are effective drugs in treating neuromyelitis optica spectrum disorders and other diseases. Thiopurines' toxicity is mainly imputed to thiopurine S-methyltransferase activity. In Chinese population, the most common and important variation of thiopurine S-methyltransferase is TPMT*3C (rs1142345). This study aims to reveal the association between thiopurine S-methyltransferase activity and genetic polymorphisms of thiopurine S-methyltransferase in patients with neuromyelitis optica spectrum disorders in China...

Antibodies targeting myelin oligodendrocyte glycoprotein (MOG) have been recently reported in association with idiopathic inflammatory central nervous system disorders. Initially believed to be a benign disorder, anti MOG-IgG was noted to cause steroid responsive recurrent optic neuritis and isolated longitudinally extensive myelitis. However, there is growing evidence that the disease may be predominantly relapsing, often producing severe visual loss and involving regions other than the spinal cord and optic nerve...

Genes encoding antigen-presenting molecules within the human major histocompatibility complex (MHC) account for the highest component of genetic risk for many neurological diseases, such as multiple sclerosis, neuromyelitis optica, Parkinson's disease, Alzheimer's disease, schizophrenia, myasthenia gravis and amyotrophic lateral sclerosis. Myriad genetic, immunological and environmental factors may contribute to an individual's susceptibility to neurological disease. Here, we review and discuss the decades long research on the influence of genetic variation at the MHC locus and the role of immunogenetic killer cell immunoglobulin-like receptor (KIR) loci in neurological diseases, including multiple sclerosis, neuromyelitis optica, Parkinson's disease, Alzheimer's disease, schizophrenia, myasthenia gravis and amyotrophic lateral sclerosis...

BACKGROUND: Brain magnetic resonance imaging (BMRI) lesions were classically not reported in neuromyelitis optica (NMO). However, BMRI lesions are not uncommon in NMO spectrum disorder (NMOSD) patients. OBJECTIVE: To report BMRI characteristic abnormalities (location and configuration) in NMOSD patients at presentation. METHODS: Medical records and BMRI characteristics of 79 patients with NMOSD (during the first documented attack) in Argentina, Brazil and Venezuela were reviewed retrospectively...

Neuromyelitis optica spectrum disorders (NMOSD) predominantly affect women who are of childbearing age. Understanding the interactions between pregnancy and NMOSD is important for clinical management. Aquaporin-4 (AQP4), the most common target antigen in NMOSD, is expressed on placenta in early pregnancy. A variety of immune and cytokine changes in pregnancy may impact pregnancy outcomes in NMOSD patients. Relapses continue during pregnancy and increase in frequency postpartum. Preeclampsia and fetal loss are more frequent in NMOSD than in controls...

We compared the retinal thickness in the unaffected eyes among the following subtypes of unilateral optic neuritis (ON): multiple sclerosis (MS-ON), neuromyelitis optica spectrum disorder with anti-AQP4 autoantibody (AQP4-ON), patients with serum anti-MOG antibody (MOG-ON), and idiopathic ON. In the chronic phase, macular GCC and circum-papillary RNFL in the unaffected eyes were both atrophied in MS-ON and AQP4-ON, but were not atrophied in the others. Titers of anti-AQP4-Ab was suggested to be associated with such latent neurodegenerative process in AQP4-ON...
