BACKGROUND: Autoantibodies, in particular those against aquaporin-4 and myelin-oligodendrocyte glycoprotein (MOG), aid as biomarkers in the differential diagnosis of demyelination. Here, we report on discovery of autoantibodies against flotillin in patients with multiple sclerosis (MS). METHODS: The target antigen was identified by histo-immunoprecipitation using the patients' sera and cryosections of rat or pig cerebellum combined with mass spectrometrical analysis...

INTRODUCTION: Multiple sclerosis (MS) is an inflammatory-demyelinating disease of the central nervous system (CNS). Autoimmune inflammation is common in the early stages of MS and is followed by neurodegenerative processes. The result of these changes is axon and myelin breakdown. The paraclinical examination methods are an important part of the diagnostic process. Magnetic resonance imaging of the brain and the cervical spinal cord and an examination of cerebrospinal fluid (CSF) are common paraclinical examinations...

Magnetic resonance imaging (MRI) is the primary method for confirming the clinical diagnosis of multiple sclerosis (MS). The article presents the current data on using MRI of the brain and spinal cord for diagnosis in suspected MS. Special attention is paid to the MRI criteria of McDonald and MAGNIMS for relapsing-remitting MS (RRMS) and primary-progressive MS (PPMS) in the latest revisions of 2010 and 2016. The information provided can help radiologists and neurologists to optimize the use of MRI in clinical practice for diagnosis of MS...

Fabry's disease (FD) is a recognised mimic of multiple sclerosis (MS). It is an X-linked storage lysosomal disorder with deficiency of α-galactosidase A and enzyme replacement therapy is available. Patients with FD may satisfy modified McDonald criteria if the diagnosis of FD has not been pursued. We present a case of FD in a 65-year-old woman masquerading as benign MS for 40 years. She has recurrent posterior circulation stroke-like symptoms, hearing loss and acroparaesthesia, but typical radiological features of MS on MRI brain...

BACKGROUND: Multiple sclerosis (MS) is the most prevalent autoimmune inflammatory demyelinating disease of the central nervous system (CNS) in young adults. More than 50 genomic regions have been associated with MS susceptibility. Due the important immune-modulating properties of Vitamin D, Vitamin D receptor (VDR) gene polymorphisms - which interfere with the actions of Vitamin D- could be related to increased risk of MS. METHODS: We studied 120 patients fulfilling the McDonald criteria for MS (81 females and 39 males) and 180 healthy unrelated controls, nested in a case-Control study, and were recruited from the National Institute of Neurology and Neurosurgery, Manuel Velasco Suárez in Mexico City...

MRI has long been established as the most sensitive in vivo technique for detecting multiple sclerosis (MS) lesions. The 2010 revisions of the McDonald Criteria have simplified imaging criteria, such that a diagnosis of MS can be made on a single contrast-enhanced MRI scan in the appropriate clinical context. New disease-modifying therapies have proven effective in reducing relapse rate and severity. Several of these therapies, most particularly natalizumab, but also dimethyl fumarate and fingolimod, have been associated with progressive multifocal leukoencephalopathy (PML)...

BACKGROUND: The usefulness of performing a spinal cord (SC) magnetic resonance imaging (MRI) in all clinically isolated syndromes (CIS) is controversial. OBJECTIVE: To assess the value of SC lesions for predicting multiple sclerosis (MS) diagnosis and disability accrual in CIS. METHODS: Concerning SC lesions and MS diagnosis (2010 McDonald), adjusted Cox regression analyses were performed in increasingly specific CIS groups: all cases ( n = 207), non-SC CIS ( n = 143), non-SC CIS with abnormal brain MRI ( n = 90) and non-SC CIS with abnormal brain MRI not fulfilling 2010 MS ( n = 67)...

Mycoplasma synoviae (MS) is a poultry pathogen that has had an increasing incidence and economic impact over the past few years. Strain identification is necessary for outbreak investigation, infection source identification, and facilitating prevention and control as well as eradication efforts. Currently, a segment of the variable lipoprotein hemagglutinin A (vlhA) gene (420 bp) is the only target that is used for MS strain identification. A major limitation of this assay is that colonality of typed samples can only be inferred if their vlhA sequences are identical; however, if their sequences are different, the degree of relatedness is uncertain...

Neuropsychiatric signs and symptoms occur frequently in individuals with multiple sclerosis (MS), either as the initial presenting complaint prior to a definitive neurological diagnosis or more commonly with disease progression. However, the pathogenesis of these comorbid conditions remains unclear and it remains difficult to accurately elucidate if neuropsychiatric symptoms or conditions are indicators of MS illness severity. Furthermore, both the disease process and the treatments of MS can adversely impact an individual's mental health...

The human health benefits of anthocyanins (Anc) and other flavonoids are widely recognized. However, the flavonoid-based urinary metabolites arising in vivo after Anc intake are not well described. Human (n = 17) urine was collected while blueberry juice (BJ) was consumed daily for 28 days and once after a 7 day washout. MS/MS scanning of 664 urine samples for 18 parent Anc (PAnc) and 42 predicted Anc metabolites (AncM) yielded 371 products (i.e., MS/MS × retention time (RT)). Flavonoid-based AncM, which were likely underestimated, were almost 20 times more abundant than PAnc...
