    Acute aphasia is rare in multiple sclerosis. We describe 3 patients with multiple sclerosis who had acute exacerbations presenting as aphasias. One patient had a mixed transcortical aphasia, 1 had a transcortical motor aphasia, and 1 had a Broca aphasia. Magnetic resonance imaging scans of the brain with contrast enhancement revealed new white matter lesions in the left hemisphere in all 3 patients. Two of the 3 patients had a good response to treatment with methylprednisolone sodium succinate. Arch Neurol. 2000;57:1207-1209

    Psychotic symptoms are infrequent in multiple sclerosis (MS) and their relationship to cerebral lesions has not been clearly documented. The case of a 58 year old woman with secondary progressive MS is presented. She had acute delirium with persecutory delusions associated to paresis of her left leg. Magnetic resonance imaging of the brain disclosed an active lesion in the left hippocampus. The patient was treated with risperidone and megadoses of methylprednisolone, with dramatic improvement. Clinical and radiological data in this patient suggest that psychotic disorders can be symptomatic of a relapse in MS and, therefore, susceptible to be treated with steroids.

  11. Acute Lymphoblastic Leukemia in a Man Treated With Fingolimod for Relapsing Multiple Sclerosis

    Directory of Open Access Journals (Sweden)

    Stanley Cohan MD, PhD

    2015-03-01

    Full Text Available A man with relapsing multiple sclerosis, treated with fingolimod 0.5 mg/d for 15 months, developed acute lymphoblastic leukemia and died 4 months after immune ablation and bone marrow allograft, from graft versus host disease. To our knowledge, this is the first case of acute lymphoblastic leukemia reported in a patient treated with fingolimod. Although no causal relationship can be established between fingolimod use and acute lymphoblastic leukemia risk in this single case, future surveillance for lymphatic cell malignancies in patients treated with fingolimod appears justified.

  12. Acute verbal dyspraxia, a rare presentation in multiple sclerosis: a case report with MRI localization.

    2003-12-01

    Cortical speech disorders rarely occur in multiple sclerosis (MS). We report a patient with relapsing-remitting MS, who presented with acute verbal dyspraxia. Magnetic resonance imaging (MRI) demonstrated an acute T2/Flair hyperintense, primarily white matter lesion underlying the middle third of the inferior frontal gyrus. The verbal dyspraxia cleared beginning 48 hours after the initiation of iv dexamethasone. Follow-up MRI demonstrated qualitative and quantitative diminution of the hyperintensity. This is the first report of a clinically definite MS patient with acute verbal dyspraxia. Moreover, there was a suggestive localization of verbal praxis to Brodmann areas 44/45.

    Multiple sclerosis can affect vision in many ways, including optic neuritis, chronic optic neuropathy, retrochiasmal visual field defects, higher order cortical processing, double vision, nystagmus and also by related ocular conditions such as uveitis. There are also side effects from recently introduced multiple sclerosis treatments that can affect vision. This review will discuss all these aspects and how they come together to cause visual symptoms. It will then focus on practical aspects of how to recognise when there is a vision problem in a multiple sclerosis patient and on what treatments are available to improve vision.

  1. Acute disseminated encephalomyelitis complicating dengue infection with neuroimaging mimicking multiple sclerosis: A report of two cases.

    2016-11-01

    Acute disseminated encephalomyelitis (ADEM) complicating dengue infection is still exceedingly rare even in endemic countries such as Malaysia. Here we report two such cases, the first in an elderly female patient and the second in a young man. Both presented with encephalopathy, brainstem involvement and worsening upper and lower limb weakness. Initial magnetic resonance imaging (MRI) of the brain was normal in the first case. Serum for dengue Ig M and NS-1 was positive in both cases. Cerebrospinal fluid (CSF) showed pleocytosis in both with Dengue IgM and NS-1 positive in the second case but not done in the first. MRI brain showed changes of perpendicular subcortical palisading white matter, callosal and brainstem disease mimicking multiple sclerosis (MS) in both patients though in the former case there was a lag between the onset of clinical symptoms and MRI changes which was only clarified on reimaging. The temporal evolution and duration of the clinical symptoms, CSF changes and neuroimaging were more suggestive of Dengue ADEM rather than an encephalitis though initially the first case began as dengue encephalitis. Furthermore in dengue encephalitis neuroimaging is usually normal or rarely edema, haemorrhage, brainstem, thalamic or focal lesions are seen. Therefore, early recognition of ADEM as a sequelae of dengue infection with neuroimaging mimicking MS and repeat imaging helped in identifying these two cases. Treatment with intravenous steroids followed by maintenance oral steroids produced good outcome in both patients. Copyright © 2016 Elsevier B.V. All rights reserved.

    Full Text Available Abstract Background The ability to predict the spatial frequency of relapses in multiple sclerosis (MS would enable physicians to decide when to intervene more aggressively and to plan clinical trials more accurately. Methods In the current study our objective was to determine if subsets of genes can predict the time to the next acute relapse in patients with MS. Data-mining and predictive modeling tools were utilized to analyze a gene-expression dataset of 94 non-treated patients; 62 patients with definite MS and 32 patients with clinically isolated syndrome (CIS. The dataset included the expression levels of 10,594 genes and annotated sequences corresponding to 22,215 gene-transcripts that appear in the microarray. Results We designed a two stage predictor. The first stage predictor was based on the expression level of 10 genes, and predicted the time to next relapse with a resolution of 500 days (error rate 0.079, p Conclusion We conclude that gene expression analysis is a valuable tool that can be used in clinical practice to predict future MS disease activity. Similar approach can be also useful for dealing with other autoimmune diseases that characterized by relapsing-remitting nature.

    In a chronic and disabling disease like multiple sclerosis, rehabilitation becomes of major importance in the preservation of physical, psychological and social functioning. Approximately 80% of patients have multiple sclerosis for more than 35 years and most will develop disability at some point...... of their lives, emphasising the importance of rehabilitation in order to maintain quality of life. An important aspect of multiple sclerosis rehabilitation is the preservation of physical functioning. Hot topics in the rehabilitation of physical function include (1) exercise therapy, (2) robot-assisted training...... and (3) pharmacological interventions. Exercise therapy has for many years been a controversial issue in multiple sclerosis rehabilitation and the advice generally given to patients was not to participate in physical exercise, since it was thought to lead to a worsening of symptoms or fatigue.

  4. Acute disseminated encephalomyelitis in children: differential diagnosis from multiple sclerosis on the basis of clinical course

    Full Text Available Acute disseminated encephalomyelitis (ADEM is a demyelinating disease of the central nervous system (CNS that typically presents as a monophasic disorder associated with multifocal neurologic symptoms and encephalopathy. ADEM is considered an autoimmune disorder that is triggered by an environmental stimulus in genetically susceptible individuals. The diagnosis of ADEM is based on clinical and radiological features. Most children with ADEM initially present with fever, meningeal signs, and acute encephalopathy. The level of consciousness ranges from lethargy to frank coma. Deep and subcortical white-matter lesions and gray-matter lesions such as thalami and basal ganglia on magnetic resonance imaging (MRI are associated with ADEM. In a child who presents with signs of encephalitis, bacterial and viral meningitis or encephalitis must be ruled out. Sequential MRI is required to confirm the diagnosis of ADEM, as relapses with the appearance of new lesions on MRI may suggest either multiphasic ADEM or multiple sclerosis (MS. Pediatric MS, defined as onset of MS before the age of 16, is being increasingly recognized. MS is characterized by recurrent episodes of demyelination in the CNS separated in space and time. The McDonald criteria for diagnosis of MS include evidence from MRI and allow the clinician to make a diagnosis of clinically definite MS on the basis of the interval preceding the development of new white matter lesions, even in the absence of new clinical findings. The most important alternative diagnosis to MS is ADEM. At the initial presentation, the 2 disorders cannot be distinguished with certainty. Therefore, prolonged follow-up is needed to establish a diagnosis.

    2008-03-15

    Purpose: The aims of the study are firstly, to determine the difference in diffusion-weighted imaging (DWI) in normal appearing white matter (NAWM) between patients with acute multiple sclerosis (MS) and controls; secondly, to determine whether there is a correlation between EDSS scores and DWI in acute plaques and also NAWM. Materials and method: Out of 50 patients with acute MS attack, 35 patients had active plaques with diffuse or ring enhancement on postcontrast images. Eighteen healthy volunteers constituted the control group. While 26 of 35 had relapsing-remitting, 9 had secondary progressive MS. Apparent diffusion coefficients (ADC) of the active plaques, NAWM at the level of centrum semiovale and occipital horn of lateral ventricle in the patients and NAWM in control group were measured. ADC values of active plaques were compared with WM of the patients and the control group. The relationship of ADC value of active plaques and WM in MS with expanded disability status scale (EDSS) was investigated by using Mann-Whitney U-test. Results: Of 63 plaques totally, 26 and 37 of the active plaques had diffuse and ring enhancement, respectively. There was no statistically significant difference between ADC value of active plaques and EDSS (p > 0.05). However, there was a statistically significant difference between ADC value of WM occipital horn and EDSS (p < 0.05). ADC value of active plaques were higher than WM in both groups (p < 0.001). The difference between ADC value of WM at the centrum semiovale (p < 0.05) and occipital horns (p < 0.001) in patients and controls was statistically significant. There was no statistically significant difference between EDSS scores, ADC value at centrum semiovale and WM around occipital horn and active plaques in subgroups (p > 0.05). Conclusion: Apparently normal tissue in MS patients may show early abnormalities when investigated carefully enough, and there is an even though moderate correlation between EDSS and ADC values and

    Full Text Available Twenty cases of isolated optic neuritis (15 female, 5 male were studied and followed for several months to years after the initial attack. The mean age of patients was 23 years (range: 15-29 years. The most frequent clinical manifestations were decreased visual acuity and blurred vision. A complete neurological examination was performed. In 15 cases (75% the initial brain MRI was abnormal. In fourteen cases, other signs of multiple sclerosis presented in one month to eight years following the initial attack of optic neuritis; eleven of the latter cases had an abnormal initial MRI. Acute optic neuritis can be considered a presenting feature of multiple sclerosis, particulary in the presence of an abnormal brain MRI.

  12. Immunopathogenesis of multiple sclerosis

    Directory of Open Access Journals (Sweden)

    Racke Michael

    2009-01-01

    Full Text Available Multiple sclerosis (MS is a suspected autoimmune disease in which myelin-specific CD4+ and CD8+ T cells enter the central nervous system (CNS and initiate an inflammatory response directed against myelin and other components of the CNS. Acute MS exacerbations are believed be the result of active inflammation, and progression of disability is generally believed to reflect accumulation of damage to the CNS, particularly axonal damage. Over the last several years, the pathophysiology of MS is being appreciated to be much more complex, and it appears that the development of the MS plaque involves a large number of cell populations, including CD8+ T lymphocytes, B cells, and Th17 cells (a population of helper T cells that secrete the inflammatory cytokine IL-17. The axonal transection and degeneration that is thought to represent the basis for progressive MS is now recognized to begin early in the disease process and to continue in the progressive forms of the disease. Molecules important for limiting aberrant neural connections in the CNS have been identified, which suppress axonal sprouting and regeneration of transected axons within the CNS. Pathways have also been identified that prevent remyelination of the MS lesion by oligodendrocyte precursors. Novel neuroimaging methodologies and potential biomarkers are being developed to monitor various aspects of the disease process in MS. As we identify the pathways responsible for the clinical phenomena of MS, we will be able to develop new therapeutic strategies for this disabling illness of young adults.

    A 34-year-old woman presented with urination difficulty and consciousness disturbance, followed by persistent neurologic findings, such as semicomatose mental status and bilateral optic neuritis, and monophasic clinical course. Cranial CT showed multifocal low density areas in cerebral white matter. The patient was clinically diagnosed as having acute disseminated encephalomyelitis. She died of sepsis four months later. Autopsy revealed multifocal large demyelinating lesions confined to the cerebral white matter, shown as low density areas on CT scans, and demyelinating plaques scattered in the optic nerves and chiasm, and cerebral peduncle. The final diagnosis was acute multiple sclerosis. The CT appearance of multifocal low density areas was most likely due to demyelinating lesions causing edema and tissue necrosis. (Namekawa, K.).

    The objectives of this study were (1) to determine how cerebrospinal fluid (CSF) neurofilament heavy chain (NfH(SM134) and NfH(SM135)) levels relate to clinical outcome in optic neuritis (ON) and multiple sclerosis (MS) relapse patients treated with high dose oral methylprednisolone; and (2...... in the MS attack trial were treated with oral methylprednisolone. In the MS attack trial group, CSF NfH(SM134) and NfH(SM135) measured at week 3 and deltaCSF NfH(SMI34) levels from baseline to week 3 were predictive of clinical outcome at week 8 and 52. In the ON group, no such association was seen. When...... both groups were combined, baseline CSF NfH(SHM134) and NfH(SM135) correlated positively with baseline enhancing lesion volume (ELV) (r(s) =0.50, P

    Full Text Available Introduction: Tuberous sclerosis is an autosomal do-minant genetic disorder that involves multiple or-gans. The predominant lesions are the hamartomas. Classically tuberous sclerosis has been characterized by a classic clinical triad of facial angiofibromas in 90%,retardation in 50-80%,seizure 80-90% and all three in 30%."nThe disease occurs in 1:100,000 persons in all races with nearly equal distribution between the sexes. "nCase Presentation: We had six patients who admitted with different presentations of tuberous sclerosis with a past history of convulsion from childhood, skin le-sions and mental retardation, also with new onset headache and changed pattern of convulsion. In physical examination facial angiofibromas and sub-ungual fibromas apparently detected. Brain CT scan study with contrast showed multiple calcified nod-ules associated with tubers and ventriculomegaly, also an enhancing enlarged nodule at foramen of mo-nro, which was suggestive of subependymal giant cell astrocytoma (SGCA. In abdominal and pelvic CT scan and ultrasonography, massive bilateral angio-myolipomatosis diagnosed. Also Focal hypodense le-sions in liver which were hyperechoic in ultrasono-graphy were diagnosed. With MRI study tubers, white matter lesions and subependymal nodules asso-ciated with SGCA were detected better. After surgery SGCA was proved."nDiscussion: Our patients had different presentations and various findings of this spectrum discussed in this lecture.

    Multiple sclerosis (MS) is the most common disabling neurologic condition in young adults and imposes high financial and quality of life costs on patients, their families, and society. Yet, developments in the battle against MS include new treatments to slow its progression and updated diagnostic criteria that can accelerate diagnosis and effective treatment. This article offers a review and update on the disease, focusing on risk factors and possible causes, symptoms, forms of MS, diagnostic criteria and tools, and the expanding array of approved treatments. It also reports on the skyrocketing cost of MS drugs, misdiagnosis, and special patient populations with MS.

    Multiple sclerosis (MS) is a complex neurodegenerative disease presenting with a diversity of clinical symptoms including palsy and cognitive impairment. We present a 59-year-old woman with a history of secondary progressive MS since 1987, who was referred to our department because of recent onset of confusion and polydipsia. Initial lab tests showed mildly elevated serum sodium levels and low urine osmolality. Under water deprivation, diuresis and low urine osmolality persisted and serum sodium levels rose above 150 mmol/l. Oral desmopressin resulted in normalisation of serum sodium as well as urine osmolarity, confirming a diagnosis of central diabetes insipidus. As drug-induced diabetes could be excluded, pituitary magnetic resonance imaging (MRI) was performed. A demyelinating lesion was detected in the hypothalamus. The patient was started on oral desmopressin treatment (0.2 mg/day). Fluid intake and serum sodium levels have since remained normal. In summary, we report the rare case of a patient presenting with diabetes insipidus due to progressive MS. Diabetes insipidus should be considered in MS patients who develop new onset of polydipsia.

    Steen, Katie; Narang, Puneet; Lippmann, Steven

    2015-01-01

    We performed a literature search regarding the safety and efficacy of electroconvulsive therapy in patients with multiple sclerosis and comorbid psychiatric symptoms. Literature review was conducted via PubMed databases. Of the cases we reviewed, most subjects with multiple sclerosis reported significant psychiatric symptom relief, with only a handful reporting neurologic deterioration. There was some evidence that active white matter lesions may be predictive of neurologic deterioration when electroconvulsive therapy is used in patients with multiple sclerosis. A brief description of the pathophysiology and effects of depression in patients with multiple sclerosis is also provided. Although no clinical recommendations or meaningful conclusions can be drawn without further investigation, the literature suggests that electroconvulsive therapy for treatment of psychiatric illnesses in patients with multiple sclerosis is safe and efficacious.

    Full Text Available Abstract Multiple sclerosis, the most common neurologic disorder of young adults, is traditionally considered to be an inflammatory, autoimmune, demyelinating disease of the central nervous system. Based on this understanding, the initial therapeutic strategies were directed at immune modulation and inflammation control. These approaches, including high-dose corticosteroids for acute relapses and long-term use of parenteral interferon-β, glatiramer acetate or natalizumab for disease modification, are at best moderately effective. Growing evidence supports that, while an inflammatory pathology characterizes the early relapsing stage of multiple sclerosis, neurodegenerative pathology dominates the later progressive stage of the disease. Multiple sclerosis disease-modifying therapies currently in development attempt to specifically target the underlying pathology at each stage of the disease, while avoiding frequent self-injection. These include a variety of oral medications and monoclonal antibodies to reduce inflammation in relapsing multiple sclerosis and agents intended to promote neuroprotection and neurorepair in progressive multiple sclerosis. Although newer therapies for relapsing MS have the potential to be more effective and easier to administer than current therapies, they also carry greater risks. Effective treatments for progressive multiple sclerosis are still being sought.

    . On the Faroes there were no cases of multiple sclerosis among native-born resident Faroese from 1900 until 1943, when the first of 21 cases had clinical onset, heralding a type 1 epidemic with peak incidence rates >10 per 100,000 for 1945-46. British troops who occupied the islands from April 1940 to September 1945 we believe brought a widespread (because of the scatter of Faroese cases), asymptomatic (because they were healthy troops), persistent infection we called the primary multiple sclerosis affection that involved a large proportion of Faroese, with clinical multiple sclerosis ensuing in a very small proportion. Primary multiple sclerosis affection itself may have been manifest there as a newly introduced cause of acute infectious gastroenteritis and is possibly the underlying cause of multiple sclerosis in general.

    2016-04-01

    Vaccinations help prevent communicable disease. To be valuable, a vaccine's ability to prevent disease must exceed the risk of adverse effects from administration. Many vaccines present no risk of infection as they are comprised of killed or non-infectious components while other vaccines consist of live attenuated microorganisms which carry a potential risk of infection-particularly, in patients with compromised immunity. There are several unique considerations with respect to vaccination in the multiple sclerosis (MS) population. First, there has been concern that vaccination may trigger or aggravate the disease. Second, disease-modifying therapies (DMTs) employed in the treatment of MS may increase the risk of infectious complications from vaccines or alter their efficacy. Lastly, in some cases, vaccination strategies may be part of the treatment paradigm in attempts to avoid complications of therapy.

    Multiple sclerosis (MS) is the most important immune-mediated demyelinated disease of human which is typically the disease of young adults. A total of 4% to 5% of MS population are pediatric. Pediatric MS is defined as the appearance of MS before the age of sixteen. About 80% of the pediatric cases and nearly all adolescent onset patients present with attacks typical to adult MS. Approximately 97% to 99% of the affected children have relapsing-remitting MS, while 85% to 95% of the adults experience such condition. MS in children is associated with more frequent and severe relapses. Treatment is the same as adults. We aimed to review the epidemiology, etiology, clinical manifestations, and treatment of MS in children. PMID:24665290

    Tumefactive demyelinating lesions are rare consequences of central nervous system (CNS) idiopathic inflammatory demyelinating diseases. Tumefactive demyelinating lesions pose a diagnostic challenge because they can mimic tumors and abscesses and because they can be caused by a heterogeneous range of disorders. This article reviews the recent literature on the clinical presentation; radiographic features; prognosis; and management of tumefactive demyelinating lesions in multiple sclerosis, acute demyelinating encephalomyelitis, neuromyelitis optica, and the rare variants of multiple sclerosis including Schilder's disease, Marburg acute multiple sclerosis, and Balo's concentric sclerosis.

    Multiple sclerosis occurs in genetically susceptible individuals, in whom an unknown environmental factor triggers an immune response, giving rise to a chronic and disabling autoimmune disease. Currently, significant progress is being made in our knowledge of the frequency and distribution of multiple sclerosis and its risk factors, genetics, pathology, pathogenesis, diagnostic and prognostic markers, and treatment. This has radically changed patients' and clinicians' expectations of multiple sclerosis and has raised hope that there will soon be a way to control the disease.

    This article reviews our current understanding and modern treatment of multiple sclerosis (MS). MS is a disabling condition resulting in devastating social and economic impacts. As MS can affect any part of the central nervous system, the presentation is often diverse; however, there are key features that can be useful in the clinic. We comment on the diagnostic criteria and review the main subtypes of MS, including clinically isolated syndrome, relapsing remitting MS, secondary progressive MS and primary progressive MS. Although the underlying aetiology of MS is still not known, we summarise those with most evidence of association. Finally, we aim to present treatment strategies for managing the acute relapse, disease-modifying therapies and MS symptoms. This review highlights that progressive MS is an area where there is currently a paucity of available disease-modifying treatments and this will be a major focus for future development.

    Keane described 2 patients with gaze-evoked blepharoclonus (BLC), a form of reflex BLC, and multiple sclerosis (MS). A search for common areas of demyelination and focal axonal atrophy (T1 black holes) of the central nervous system (CNS) in 11 patients with MS exhibiting eyelid closure BLC was conducted employing magnetic resonance imaging (MRI). Finding lesions in common CNS locations on these patients can help to elucidate the pathogenesis of this restricted movement disorder. Eleven adult patients with relapsing-remitting, primary or secondary progressive MS were studied. MRI views were completed employing a 1.5-tesla scanner. Contrast Axial T1 imaging was obtained in 9 patients. TL blackholes were not identified. Ten patients had multiple, scattered periventricular (PV) areas of demyelination. Four patients exhibited brainstem lesions of diverse but inconsistent locations including midbrain, cerebellar peduncle, pons and medulla. In 2 of the patients the brainstem lesions were transient but BLC persisted after the lesions regressed. No common areas of CNS demyelination or focal axonal atrophy were identified on these patients with MS and BLC. The pathogenesis and clinical significance of BLC in MS remains to be elucidated.

    We investigated a possible causal relation between exposure to organic solvents in Danish workers (housepainters, typographers/printers, carpenters/cabinetmakers) and onset of multiple sclerosis. Data on men included in the Danish Multiple Sclerosis Register (3,241 men) were linked with data from......, and butchers. Over a follow-up period of 20 years, we observed no increase in the incidence of multiple sclerosis among men presumed to be exposed to organic solvents. It was not possible to obtain data on potential confounders, and the study design has some potential for selection bias. Nevertheless......, the study does not support existing hypotheses regarding an association between occupational exposure to organic solvents and multiple sclerosis....

    The Vaccine Adverse Event Reporting System (VAERS), administered by the FDA and CDC, is the U.S. system for surveillance of vaccine adverse events (AE). Acute encephalopathy age or =18 months (EO > or = 18), encephalitis (EI), and multiple sclerosis (MS) after vaccination have been reported to VAERS, but reports often contain insufficient information to validate diagnoses. Standardized case definitions would enhance the utility of VAERS reports for AE surveillance. We developed practical case definitions for classification of VAERS reports, and three neurologists independently applied the definitions to reports submitted in 1993. Inter-observer agreement was assessed, and non-concordant classifications were reviewed in a follow-up conference call. Reports of EO or = 18 (n = 20), EI (n = 15), and MS (n = 16) were classified as "definite" in 7% to 30% of the cases, while 26% to 51% of reports were thought to have insufficient information to make a classification. Agreement among reviewers was good to excellent, (kappa: 0.65 to 0.85) except for EO Elsevier Science Inc.

  2. Necrotizing meningoencephalitis of Pug dogs associates with dog leukocyte antigen class II and resembles acute variant forms of multiple sclerosis.

    2010-08-01

    Necrotizing meningoencephalitis (NME) is a disorder of Pug Dogs that appears to have an immune etiology and high heritability based on population studies. The present study was undertaken to identify a genetic basis for the disease. A genome-wide association scan with single tandem repeat (STR) markers showed a single strong association near the dog leukocyte antigen (DLA) complex on CFA12. Fine resolution mapping with 27 STR markers on CFA12 further narrowed association to the region containing DLA-DRB1, -DQA1 and, -DQB1 genes. Sequencing confirmed that affected dogs were more likely to be homozygous for specific alleles at each locus and that these alleles were linked, forming a single high risk haplotype. The strong DLA class II association of NME in Pug Dogs resembles that of human multiple sclerosis (MS). Like MS, NME appears to have an autoimmune basis, involves genetic and nongenetic factors, has a relatively low incidence, is more frequent in females than males, and is associated with a vascularly orientated nonsuppurative inflammation. However, NME of Pug Dogs is more aggressive in disease course than classical human MS, appears to be relatively earlier in onset, and involves necrosis rather than demyelination as the central pathobiologic feature. Thus, Pug Dog encephalitis (PDE) shares clinical features with the less common acute variant forms of MS. Accordingly, NME of Pug Dogs may represent a naturally occurring canine model of certain idiopathic inflammatory disorders of the human central nervous system.

    2011-01-01

    Symptoms management in multiple sclerosis is an integral part of its care. Accurate assessment and addressing the different symptoms provides increased quality of life among patients with multiple sclerosis. Multiple sclerosis symptoms may be identified as primary, secondary, or tertiary symptoms. Primary symptoms, such as weakness, sensory loss, and ataxia, are directly related to demyelination and axonal loss. Secondary symptoms, such as urinary tract infections as a result of urinary retention, are a result of the primary symptoms. Tertiary symptoms, such as reactive depression or social isolation, are a result of the social and psychological consequences of the disease. Common multiple sclerosis symptoms include fatigue and weakness; decreased balance, spasticity and gait problems; depression and cognitive issues; bladder, bowel, and sexual deficits; visual and sensory loss; and neuropathic pain. Less-common symptoms include dysarthria and dysphagia, vertigo, and tremors. Rare symptoms in multiple sclerosis include seizures, hearing loss, and paralysis. Symptom management includes nonpharmacological methods, such as rehabilitation and psychosocial support, and pharmacological methods, ie, medications and surgical procedures. The keys to symptom management are awareness, knowledge, and coordination of care. Symptoms have to be recognized and management needs to be individualized. Multiple sclerosis therapeutics include nonpharmacological strategies that consist of lifestyle modifications, rehabilitation, social support, counseling, and pharmacological agents or surgical procedures. The goal is vigilant management to improve quality of life and promote realistic expectations and hope.

    2007-01-01

    Multiple sclerosis (MS) is one of the most frequently seen neurological causes of progressive disability in early to middle adulthood. The disease is variable in its presentation and course, affects roughly 100-300 per 100,000 persons within the United States alone, and is slightly more common among females than males. MS places substantial burdens on patients, families, and caregivers. It negatively affects cognitive abilities and psychiatric functioning, and can add a notably deleterious effect on a patient's quality of life. This chapter reviews the recent literature on the behavioral manifestations of MS. Cognitive domains discussed include executive functioning, processing speed, attention, learning and memory, language functioning, and visual spatial processing. Some attention will also be paid to differential diagnosis and the cognitive effects of treatment. Psychiatric manifestations are also discussed, including symptoms of depression, bipolar disorder, euphoria, pathological laughter and crying, and psychosis, as well as maladaptive personality traits. Finally, the chapter concludes with a discussion of the effects of MS on quality of life including such areas as fatigue, sexual dysfunction, pain, employment, and cognitive functioning.

    Objective To explore the effect of leptin on cytokine production by PBMCs obtained from MS patients either in acute (relapse) or in stable (nonrelapse) phase of disease. Methods PBMCs were collected from 25 untreated acute MS patients, 11 stable MS patients and 20 healthy controls. PBMCs were cultured either with RPMI-1640 alone or with leptin (1.25 nmol/ml), phytohemagglutinin (PHA) ( 100 μg/ml), and leptin + PHA. 72 h later the supernate of the culture medium were collected and stored at -70℃. The pro-inflammatory cytokine (IFN-γ) concentration were determined using an enzyme-linked immunosorbent assay ( ELISA), and the anti-inflammatory cytokine (IL-4) concentration were investigated by radioimmunity methods. Results Our data showed that leptin induced IFN-γproduction by PBMCs of patients in an acute phase of disease but not in a stable phase or in healthy controls. Moreover, we found that PHA induced IL-4 production by PBMCs of patients in an acute phase of disease, but leptin inhibited this ability of PHA. Conclusion Leptin can affect on pro- and anti-inflammatory cytokine production by PBMCs collected from MS patients, may be this connected with leptin increase the susceptiveness of MS.

    Objetivo. Describir los factores que estan relacionados con el realce de gadolinio en la resonancia magnetica (RM) en pacientes con esclerosis multiple (EM) con sintomas de recaida. Pacientes y metodos. Estudio observacional de corte transversal, retrospectivo, de pacientes mayores de 18 años con diagnostico de EM remitente recurrente o progresiva, que presentaron actividad clinica y a quienes se les realizo resonancia cerebral y medular con contraste durante la fase aguda de los sintomas. Resultados. De los 93 pacientes incluidos, el 70% fueron mujeres, con una edad media de 37 ± 9,6 años. El 90% presentaba un diagnostico de EM remitente recurrente y el 50% tenia una duracion de la enfermedad de al menos cinco años. El 56% presento actividad clinica de origen medular, y las alteraciones sensitivas fueron las mas frecuentes (44%). La mediana de duracion de los sintomas fue de seis dias (rango: 1-89 dias). El 93% requirio tratamiento con metilprednisolona intravenosa durante 3-5 dias, que se administro despues de realizar los estudios de RM. La presencia de lesiones que realzaran con contraste durante la fase de recaida en los estudios de RM no mostro relacion significativa con ninguna de las variables clinicas analizadas y solo se observo una tendencia con los sintomas asociados (p = 0,07). Conclusiones. La definicion de recaida en la EM es clinica. Una RM en la fase de recaida podria ser util para confirmar la actividad de la enfermedad, pero el realce de gadolinio durante la recaida no se encontro que fuera determinado por la presentacion clinica, la localizacion anatomica o la duracion del sintoma.

    A number of studies have been conducted with the onset of secondary progressive multiple sclerosis as an inclusion criterion or an outcome of interest. However, a standardized objective definition of secondary progressive multiple sclerosis has been lacking. The aim of this work was to evaluate the accuracy and feasibility of an objective definition for secondary progressive multiple sclerosis, to enable comparability of future research studies. Using MSBase, a large, prospectively acquired, global cohort study, we analysed the accuracy of 576 data-derived onset definitions for secondary progressive multiple sclerosis and first compared these to a consensus opinion of three neurologists. All definitions were then evaluated against 5-year disease outcomes post-assignment of secondary progressive multiple sclerosis: sustained disability, subsequent sustained progression, positive disability trajectory, and accumulation of severe disability. The five best performing definitions were further investigated for their timeliness and overall disability burden. A total of 17 356 patients were analysed. The best definition included a 3-strata progression magnitude in the absence of a relapse, confirmed after 3 months within the leading Functional System and required an Expanded Disability Status Scale step ≥4 and pyramidal score ≥2. It reached an accuracy of 87% compared to the consensus diagnosis. Seventy-eight per cent of the identified patients showed a positive disability trajectory and 70% reached significant disability after 5 years. The time until half of all patients were diagnosed was 32.6 years (95% confidence interval 32-33.6) after disease onset compared with the physicians' diagnosis at 36 (35-39) years. The identified patients experienced a greater disease burden [median annualized area under the disability-time curve 4.7 (quartiles 3.6, 6.0)] versus non-progressive patients [1.8 (1.2, 1.9)]. This objective definition of secondary progressive multiple

    Full Text Available James P Simsarian, Carol Saunders, D Michelle SmithNeurology Center of Fairfax Ltd, Fairfax, VA, USABackground: Despite over 50 years of experience with adrenocorticotropic hormone (ACTH as a treatment for acute exacerbations of multiple sclerosis, there have been no trials examining the options of the 2–3-week dosing regimen or intramuscular injection protocol used in the original trials. At our clinic, we performed a small, prospective, randomized pilot study to examine the efficacy and safety of, and patient satisfaction with, a short (five-day self-administered ACTH dosing protocol for exacerbations of multiple sclerosis, and to compare the subcutaneous and intramuscular routes of administration.Methods: Patients for this study were recruited from an outpatient treatment clinic. Each patient self-administered natural ACTH gel 80 U/day by subcutaneous or intramuscular injection for five consecutive days and was evaluated at baseline and on days 7 and 14. Patient feedback was collected using the Patient Global Impression of Change (PGI-C, the primary efficacy measure, a patient global visual analog scale, the Expanded Disability Status Scale, a timed walk, the Nine-hole Peg Test, and the Clinical Global Impression of Change.Results: Of the 20 enrolled patients (mean age 39.5 years, 19 completed the study. On day 14, 61.1% of patients (11 of 18 with day 14 scores were treatment responders, and rated their condition as "very much improved" or "much improved" on the PGI-C. The intramuscular group had numerically more responders, but there was no significant difference in the proportion of responders between the intramuscular and subcutaneous groups at day 14 (P = 0.3. The intramuscular route of injection was associated with more injection site pain than the subcutaneous route.Conclusion: A shorter five-day course of intramuscular or subcutaneous ACTH gel may improve symptoms associated with acute exacerbations of multiple sclerosis.

    Full Text Available Background. Uveitis is 20 times more frequent in multiple sclerosis (MS patients than in the general population. Methods. A retrospective study of local multiple sclerosis (n=700 and uveitis cohorts (n=450 described the ophthalmological and neurological characteristics of patients with multiple sclerosis and uveitis. Results. Uveitis and multiple sclerosis were associated in seven patients. The time intervals between diagnoses of MS and uveitis ranged from 6 months to 15 years. Analysis of the patients’ characteristics revealed that multiple sclerosis was associated with an older age of onset than usually expected, that is, 39 years. Uveitis was bilateral in three cases and mainly posterior (5/10. Five patients presented with acute optic neuritis (two in one eye and three in both eyes. All eyes presenting with acute optic neuritis were also affected by uveitis (P=0.02, though not simultaneously. Conclusion. The ipsilateral association between optic neuritis and uveitis in this series of patients with multiple sclerosis may suggest a reciprocal potentiation between optic neuritis and uveitis in multiple sclerosis.

  6. Multiple sclerosis and herpesvirus interaction

    2013-09-01

    Full Text Available Multiple sclerosis is the most common autoimmune inflammatory demyelinating disease of the central nervous system, and its etiology is believed to have both genetic and environmental components. Several viruses have already been implicated as triggers and there are several studies that implicate members of the Herpesviridae family in the pathogenesis of MS. The most important characteristic of these viruses is that they have periods of latency and exacerbations within their biological sanctuary, the central nervous system. The Epstein-Barr, cytomegalovirus, human herpesvirus 6 and human herpesvirus 7 viruses are the members that are most studied as being possible triggers of multiple sclerosis. According to evidence in the literature, the herpesvirus family is strongly involved in the pathogenesis of this disease, but it is unlikely that they are the only component responsible for its development. There are probably multiple triggers and more studies are necessary to investigate and define these interactions.

    Multiple sclerosis (MS) is a chronic demyelinating disease of the central nervous system. Although the exact underlying mechanism leading to myelin destruction is unknown, the molecular mimicry theory is the most commonly acknowledged elucidation of MS pathology. Although various antigens have been associated with MS induction, this review presents studies focused on key bacterial and viral antigens that lead to the development of MS. The research specific to a molecular mimicry theory of MS via each implicated agent is weak; however, collectively the reports provide credible support for this theory. Given that homologous sequences are not required to lead to antigenic cross-reactivity, it is reasonable to conclude that certain viral and bacterial antigens with 5-10 similar amino acids in sequence can lead to self destruction of similar myelin sequences. Thus, this literature review has provided insight to further the understanding of the etiology of multiple sclerosis.

    Full Text Available Ever since the introduction of the first disease modifying therapies, the concept of multiple sclerosis treatment algorithms developed ceaselessly. The increasing number of available drugs is paralleled by impelling issue of ensuring the most appropriate treatment to the right patient at the right time. The purpose of this review is to describe novel agents recently approved for multiple sclerosis treatment, namely teriflunomide, alemtuzumab and dimethylfumarate, focusing on mechanism of action, efficacy data in experimental setting, safety and tolerability. The place in therapy of newer treatment implies careful balancing of risk-benefit profile as well as accurate patient selection. Hence the widening of therapeutic arsenal provides greater opportunity for personalized therapy but also entails a complex trade-off between efficacy, tolerability, safety and eventually patient preference.

    Multiple sclerosis is an inflammatory disease leading to disseminated lesions of the central nervous system resulting in both somatomotor and autonomic disturbances. These involve the central centers of the autonomic nervous system, as well as the automatic control and pathway systems. All autonomic functions may be disordered individually or in combined form. There is no other disease with a clinical picture so multifaceted. Besides cardiovascular dysfunctions disorders of bladder and rectum have become apparent. Somatomotor and autonomic disturbances occur with similar frequency; however the focused exam often heavily favors somatomotor symptoms. Autonomic disturbances should primarily be taken into account on history taking and clinical examination. Individual diagnosis and treatment is a secondary feature. Impairments of the autonomic nervous systems in multiple sclerosis are frequently overlooked.

    Magnetic Resonance Imaging was performed in more than 200 patients with clinical suspicion or knowledge of Multiple Sclerosis. One hundred and forty-seven (60 males and 87 females) had MR evidence of multiple sclerosis lesions. The MR signal of demyelinating plaques characteristically has prolonged T1 and T2 relaxation times and the T2-weighted spin-echo sequences are generally superior to the T1-weighted images because the lesions are better visualized as areas of increased signal intensity. MR is also able to detect plaques in the brainstem, cerebellum and within the cervical spinal cord. MR appears to be an important, non-invasive method for the diagnosis of Multiple Sclerosis and has proven to be diagnostically superior to CT, evoked potentials (EP) and CSF examination. In a selected group of 30 patients, with the whole battery of the relevant MS studies, MR was positive in 100%, CT in 33,3%, EP in 56% and CSF examination in 60%. In patients clinically presenting only with signs of spinal cord involvement or optic neuritis or when the clinical presentation is uncertain MR has proven to be a very useful diagnostic tool for diagnosis of MS by demonstrating unsuspected lesions in the cerebral hemispheres.

    Before the development of magnetic resonance imaging (MRI), evoked potentials (EPs)-visual evoked potentials, somatosensory evoked potentials, and brain stem auditory evoked responses-were commonly used to determine a second site of disease in patients being evaluated for possible multiple sclerosis (MS). The identification of an area of the central nervous system showing abnormal conduction was used to supplement the abnormal signs identified on the physical examination-thus identifying the "multiple" in MS. This article is a brief overview of additional ways in which central nervous system (CNS) physiology-as measured by EPs-can still contribute value in the management of MS in the era of MRIs.

    2015-01-01

    Full Text Available INTRODUCTION Multiple sclerosis is an immune-mediated disease that produces chronic inflammation and neural degeneration. The disease progresses with acute attacks that result in myelin inflammation. This in turn increases oxidative stress and favors the appearance of reactive oxygen species. Reactive oxygen species damage neural cells causing apoptosis. The etiology of multiple sclerosis remains unknown and current therapy is aggressive and expensive. Recently, complementary and alternative medicine therapies have been proposed to control pathogenesis and symptoms of this disease. It is believed that these therapies help slow the progression of multiple sclerosis and improve survival. METHODS We conducted a MEDLINE/PubMed search using the following MeSH terms: diet, multiple sclerosis, antioxidants. We selected the main articles containing multiple sclerosis and diet. RESULTS We analyzed three case control studies that evaluated different dietary approaches in multiple sclerosis. For this review, we also included five experimental studies that studied the efficacy of lipoic acid in humans and rodents in diseases like multiple sclerosis, experimental autoimmune encephalomyelitis, and breast cancer.

    Multiple sclerosis is characterized by temporal and spatial dissemination of demyelination in the central nervous system. After a discovery of disease modifying effects of interferon beta and glatiramer acetate for multiple sclerosis, many drugs for disease modifying therapy have been developed. Recently, some multicenter studies have shown that early introduction of interferon beta or glatiramer acetate into patients with clinically isolated syndrome delayed the conversion to clinically definite multiple sclerosis. Newly developed disease modifying therapies for multiple sclerosis have a specific molecular target changing an immunological reaction and many of them are oral preparations instead of injectable first line therapies. Treatment options for multiple sclerosis are increasing and it is essential for the optimal treatment choice to collect information of the long-term side effects and the combined effects with first line therapies and to acquire the knowledge of the pathomechanisms about multiple sclerosis.

    Introduccion. La esclerosis multiple (EM) es una enfermedad autoinmune de etiologia compleja, hoy por hoy desconocida, en la que factores geneticos y ambientales determinan la susceptibilidad. En los ultimos años, el efecto del tabaco ha sido uno de los factores ambientales que ha emergido en la EM, y se ha asociado tanto a un aumento de la susceptibilidad como a un aumento de la progresion. Objetivo. Revisar la evidencia actual sobre el papel del tabaco en la EM. Desarrollo. Se incluye una actualizacion de los estudios publicados que han analizado distintos aspectos del tabaco en la EM: vias patogenicas implicadas, asociacion del tabaco y riesgo de EM, interaccion con otros factores de riesgo y efecto del tabaco en el curso de la enfermedad. Conclusiones. Los estudios observacionales demuestran que el tabaquismo incrementa de forma significativa el riesgo de EM (odds ratio ~ 1,5) y es un factor de riesgo independiente. Sin embargo, la EM es una enfermedad compleja y el aumento de riesgo por el tabaco puede diferir en funcion de la interaccion con otros factores geneticos y ambientales. El papel del tabaco como factor de progresion es mas controvertido, con resultados contradictorios y estudios de gran variabilidad, lo que dificulta establecer una conclusion firme. Los mecanismos por los que el tabaquismo modifica el riesgo y posiblemente la progresion de la enfermedad no son aun conocidos.

But they also have greater risks. As further treatments emerge (daclizumab and ocrelizumab are likely to be licensed in the next two years, the physician needs to be able to place them within a complex landscape of drugs and a specific treatment strategy, which may be an "escalation" or "induction" approach.

    Full Text Available Cognitive impairment can emerge in the earliest phases of multiple sclerosis. It strongly impacts different aspects of Multiple Sclerosis (MS patients' lives, like employment, social relationships and the overall quality of life; thus, its on-time recognition and treatment is mandatory. This paper discusses issues, diagnostic methods and treatment options for cognitive dysfunctions in MS. This paper is a descriptive review of the related studies in the recent 10 years, performing a keyword search in the main databases4T. Cognitive impairment mostly involves aspects of information processing, memory and executive functioning in MS. Neuropsychological tests like MACFIMS and BRB-N are recommended for its assessment. Still, there is no fully efficient treatment for cognitive impairment. Researchers have shown some positive effects, using disease-modifying therapies and cognitive rehabilitation. Depression, pain, fatigue and other factors influencing cognitive functions must be paid attention to4T. Recognizing cognitive impairment as a major symptom for MS, makes studying this subject one of the priorities in dealing with the disease. Therefore, a consecutive research for identification and management of this part of quality of life in MS patients is obligatory4T.4T

    Directory of Open Access Journals (Sweden)

    Noha t. Abokrysha

    2008-05-01

    Full Text Available Multiple sclerosis (MS is widely believed to be an autoimmune disorder. Another exciting idea regarding the aetiology of MS may be that the immune response in MS could result from a chronic infection rather than autoimmunity in the usual sense. M. leprae-induced myelin damage in the early infectious process provides valuable insights into the pathologic mechanisms of multiple sclerosis. However, no research has hypothesized the possible involvement of mycobacterium leprae or its components in pathogenesis of MS. Most of the antigens of mycobacterium leprae and mycobacterium tuberculosis are members of stress protein families. Of the M. leprae and M. tuberculosis antigens identified by monoclonal antibodies, all except the 18-kDa M. leprae antigen and the 19-kDa M. tuberculosis antigen are strongly coded with very similar genes. I hypothesize that MS is a syndrome of diseases, induced by intradermal BCG vaccine which may contain the antigen component resembling that of leprae that can either produce central demyelination by itself, or by delayed hypersensitivity. The hypothesis should be assessed in several experimental and clinical trials. If my hypothesis can be verified experimentally and clinically, then measurements to prevent MS disease could be accomplished.

    Full Text Available Multiple sclerosis (MS is a chronic progressive disease which is one of the leading causes of handicap in young subjects. Despite the availability of advanced disease-modifying and symptomatic therapies, there is still a need for complex rehabilitation interventions in order to compensate functional deficits, to minimize limitations in activity, to increase independence and quality of life of MS patients. Individualized programs elaborated by a multidisciplinary team of experts are the key to success of rehabilitation. Treatment should be adapted depending on: the individual patient's needs, demands of their surrounding environment, type and degree of disability, and treatment goals. The main objective of rehabilitation is, therefore, to ease the burden of symptoms by improving self-performance and independence. The methods used are: function conservation , optimization of restant capacities, compensation of functional deficits and prevention of complications. Benefits of rehabilitation interventions are generally higher in earlier phases of MS. Inpatient and outpatient multidisciplinary rehabilitation has been shown to be beneficial in improving disability. Outcome measures applied for patients with MS include: the EDSS score, the Barthel index and the FIM (Functional Independence Measure. The coexistence of physical and cognitive impairments, together with the imprevisible evolution of the disease makes MS rehabilitation very challenging. Rehabilitation is a valuable tool in the overall management of MS patients, the improvements obtained after treatment sessions often outlast the treatment period by several months. Neurorehabilitation methods are important tools in developing complex management strategies for patients with multiple sclerosis.

    Full Text Available Fingolimod, an oral sphingosine 1-phosphate (S1P receptor modulator, is approved for the treatment of relapsing forms of multiple sclerosis (MS. The interference with S1P signaling leads to retention particularly of chemokine receptor-7 (CCR7 expressing T cells in lymph nodes. The immunological basis of varicella zoster virus (VZV infections during fingolimod treatment is unclear. Here, we studied the dynamics of systemic and intrathecal immune responses associated with symptomatic VZV reactivation including cessation of fingolimod and initiation of antiviral therapy. Key features in peripheral blood were an about two-fold increase of VZV-specific IgG at diagnosis of VZV reactivation as compared to the previous months, a relative enrichment of effector CD4+ T cells (36% versus mean 12% in controls, and an accelerated reconstitution of absolute lymphocytes counts including a normalized CD4+/CD8+ ratio and reappearance of CCR7+ T cells. In cerebrospinal fluid (CSF the lymphocytic pleocytosis and CD4+/CD8+ ratios at diagnosis of reactivation and after nine days of fingolimod discontinuation remained unchanged. During this time CCR7+ T cells were not observed in CSF. Further research into fingolimod-associated VZV reactivation and immune reconstitution is mandatory to prevent morbidity and mortality associated with this potentially life-threatening condition.

    Patients with multiple sclerosis reported less left ear numbers but more right ear numbers than controls in a dichotic listening test. The multiple sclerosis patients were also relatively impaired on three learning tasks; one of these, a test for paired-associate learning of names and faces, correlated with left ear findings; the results are interpreted as supporting a hypothesised disconnection mechanism.

  13. Acute cerebral vasculopathy in systemic sclerosis.

    Science.gov (United States)

    Faucher, Benoit; Granel, Brigitte; Nicoli, Francois

    2013-12-01

    Systemic sclerosis is an autoimmune disease characterized by skin and deep organ fibrosis and obliterative microvasculopathy. Cerebral involvement is currently not recognized as a manifestation of the disease, although several morphologic and functional studies suggested a frequent cerebral involvement in systemic sclerosis. We report a new case of acute cerebral vasculopathy in a patient suffering from systemic sclerosis together with five historical cases identified through a literature review. Cerebral acute vasculopathy most often revealed the disease. Affected patients suffered often from limited or diffuse cutaneous systemic sclerosis. Reversibility of arterial lesions, absence of specific histologic findings, and association with severe peripheral vascular involvement plead for a major role of vasospasm. However, the apparent efficacy of immunosuppressive treatments suggests an association with inflammatory or immune mechanisms. Awareness should be raised because of the severity of the disease, the risk of relapse, and the possible occurrence early in the course of systemic sclerosis.

  14. Multiple sclerosis beyond EDSS: depression and fatigue.

    Science.gov (United States)

    Ziemssen, Tjalf

    2009-02-01

    Depression and fatigue are common symptoms of multiple sclerosis and are the primary determinants of impaired quality of life in this demyelinating neurological disease. The twelve-month prevalence of major depression in patients with multiple sclerosis is around 15%. Untreated depression is associated with suicidal ideation, impaired cognitive function and poor adherence to immunomodulatory treatment. For these reasons, systematic screening and management of depressive symptoms is recommended for all patients with multiple sclerosis. There is some evidence that interferon-beta treatment may exacerbate depressive symptoms and a switch to glatiramer acetate can be envisaged in patients treated with an interferon-beta in whom depressive symptoms become an issue. Fatigue is present in over three-quarters of patients with multiple sclerosis. It is considered the most debilitating symptom of the disease and is a major reason for work absenteeism. There is growing evidence that immunomodulatory treatments, in particular glatiramer acetate, improve fatigue symptoms in patients with multiple sclerosis.

    Full Text Available Experience with therapeutic plasma exchange (TPE for acute relapses in clinically isolated syndrome (CIS or multiple sclerosis (MS patients has been derived from small and inhomogeneous patient populations so far. In the present study, we retrospectively evaluated features associated with TPE response in a larger cohort of CIS and MS patients with acute worsening of disease.Ninety CIS and MS patients with acute relapses or acute worsening of symptoms were firstly treated with TPE. The population consisted of 62 women and 28 men with a median age of 38 years (range 18-69 years.Primary endpoint was the clinical response to TPE, focused on the functional improvement of the target neurologic deficit. Secondary endpoint was an improvement in expanded disability status scale (EDSS scoring.A clinical response to TPE was observed in 65 out of 90 patients (72.2%, with marked improvement in 18 (20.0% and moderate improvement in 47 out of 90 patients (52.2%. The median EDSS was reduced from 3.75 before to 3.0 after TPE (p = 0.001. Response to TPE was significantly more frequent in patients with relapsing courses of disease (CIS, RR-MS, p = 0.001, no disease modifying drugs (p = 0.017, gadolinium-positive (Gd+ MRI lesions (p = 0.001 and EDSS ≤ 5.0 before TPE (p = 0.014. In the multiple logistic regression analysis only the detection of Gd+ MRI lesions was significantly altered (p = 0.004.Clinical response to TPE was achieved in the majority of our patients. We identified clinical and diagnostic features in CIS and MS relapses that might be helpful to identify patients responding to TPE. Gd+ MRI lesions before treatment were the best predictor of the response to TPE in our cohort.

    MR imaging is very useful in detecting the intracranial lesion of multiple sclerosis (MS). We present six patients of MS with atypical MR imaging findings. Six patients aged 27-56 years (mean 36 years), and sexuality of six patients were 2 men and 4 females. Three patient`s clinical course had episodes of optic neuritis. The plaque`s size of the predominant lesion of the patients ranged from 3.0 to 9.0 cm in diameter. The plaques were oval, elliptically and other shaped. At acute stage, MR imaging detected perfocal edema and focal mass effect in three cases of our study. Two out of six cases showed multiple irregularly enhancing lesion with Gadolinium-DTPA. Plaques of all cases did not disappear completely in final MR imaging study. (author).

    Highlights: • We studied radiosensitivity to in vitro γ-irradiated lymphocytes from MS patients. • Immunotherapy in RRMS patients reduced the yield of radiation induced MN. • The group of treated RRMS accounts for the low radiosensitivity in MS patients. • Spontaneous yield of MN was similar in treated and untreated RRMS patients. - Abstract: Multiple sclerosis is a clinically heterogeneous autoimmune disease leading to severe neurological disability. Although during the last years many disease-modifying agents as treatment options for multiple sclerosis have been made available, their mechanisms of action are still not fully determined. In the present study radiosensitivity in lymphocytes of patients with relapsing–remitting multiple sclerosis, secondary progressive multiple sclerosis and healthy controls was investigated. Whole blood cultures from multiple sclerosis patients and healthy controls were used to analyze the spontaneous and radiation-induced micronuclei in binucleated lymphocytes. A subgroup of patients with relapsing–remitting multiple sclerosis was treated with immunomodulatory agents, interferon β or glatiramer acetate. The secondary progressive multiple sclerosis patients group was not receiving any treatment. Our results reveal that the basal DNA damage was not different between relapsing–remitting and secondary progressive multiple sclerosis patients, and healthy controls. No differences between gamma-irradiation induced micronuclei frequencies in binucleated cells from relapsing–remitting and secondary progressive multiple sclerosis patients, and healthy controls were found either. Nevertheless, when we compared the radiation induced DNA damage in binucleated cells from healthy individuals with the whole group of patients, a reduction in the frequency of micronuclei was obtained in the patients group. Induced micronuclei yield was significantly lower in the irradiated samples from treated relapsing–remitting multiple

  19. Implicit Memory in Multiple Sclerosis

    G. Latchford

    1993-01-01

    Full Text Available A number of neuropsychological studies have revealed that memory problems are relatively common in patients with multiple sclerosis (MS. It may be useful to compare MS with conditions such as Huntington's disease (HD, which have been referred to as subcortical dementia. A characteristic of these conditions may be an impairment in implicit (unconscious memory, but not in explicit (conscious memory. The present study examined the functioning of explicit and implicit memory in MS. Results showed that implicit memory was not significantly impaired in the MS subjects, and that they were impaired on recall but not recognition. A correlation was found between implicit memory performance and disability status in MS patients. Findings also suggest the possibility of long-term priming of implicit memory in the control subjects. The implications of these results are discussed.

  20. Epigenetic Drugs for Multiple Sclerosis.

    Peedicayil, Jacob

    2016-01-01

    There is increasing evidence that abnormalities in epigenetic mechanisms of gene expression contribute to the development of multiple sclerosis (MS). Advances in epigenetics have given rise to a new class of drugs, epigenetic drugs. Although many classes of epigenetic drugs are being investigated, at present most attention is being paid to two classes of epigenetic drugs: drugs that inhibit DNA methyltransferase (DNMTi) and drugs that inhibit histone deacetylase (HDACi). This paper discusses the potential use of epigenetic drugs in the treatment of MS, focusing on DNMTi and HDACi. Preclinical drug trials of DNMTi and HDACi for the treatment of MS are showing promising results. Epigenetic drugs could improve the clinical management of patients with MS.

    1999-01-01

    The range of neuropsychiatric symptoms in multiple sclerosis (MS) has not been prospectively assessed. The authors, working at a tertiary medical center in Mexico City, used the Neuropsychiatric Inventory (NPI) to evaluate neuropsychiatric symptoms prospectively in 44 MS patients who were stable between relapses and 25 control subjects of similar age, education, and cognitive function. Neuropsychiatric symptoms were present in 95% of patients and 16% of control subjects. Changes present were depressive symptoms (79%), agitation (40%), anxiety (37%), irritability (35%), apathy (20%), euphoria (13%), disinhibition (13%), hallucinations (10%), aberrant motor behavior (9%), and delusions (7%). The only relationships with MRI were between euphoria and hallucinations and moderately severe MRI abnormalities. The authors conclude that diverse types of neuropsychiatric symptoms are common in MS; symptoms are present between exacerbations; and there are variable correlations with MRI abnormalities.

  2. Gait Variability and Multiple Sclerosis

    Full Text Available Gait variability, that is, fluctuations in movement during walking, is an indicator of walking function and has been associated with various adverse outcomes such as falls. In this paper, current research concerning gait variability in persons with multiple sclerosis (MS is discussed. It is well established that persons with MS have greater gait variability compared to age and gender matched controls without MS. The reasons for the increase in gait variability are not completely understood. Evidence indicates that disability level, assistive device use, attentional requirement, and fatigue are related to gait variability in persons with MS. Future research should address the time-evolving structure (i.e., temporal characteristics of gait variability, the clinical importance of gait variability, and underlying mechanisms that drive gait variability in individuals with MS.

    2014-07-01

    Full Text Available Multiple sclerosis is a chronic autoimmune inflammatory disease of the central nervous system, characterized by the presence of acute focal inflammatory demyelination, axonal loss and gliosis. It affects predominantly in young adults between 20 and 40 years of age; it is infrequent in the pediatric age. A observational, retrospective and descriptive cohort research was conducted between May 1999 and January 2012 to assess demographic characteristics, and pathological manifestations in the oral cav- ity of children with this condition. Records of 17 patients, under 18 years of age, of either sex were included, who had been evaluated in the Department of Stomatology. Data recorded were age, sex, State of origin, oral and facial pathological features, focal cavity infections and ceod index. There were no patients with trigeminal neuralgia or facial paralysis; a 5.7% ceod index was identified. Most of the patients were under immunopressive treatment. A protocol for stomatological follow-up in patients with multiple sclerosis does not exist. The medical profession must be sensibilized to establish strategies for an integral follow-up in patients with this condition.

    2013-02-01

    Alemtuzumab is a humanized monoclonal antibody directed against CD52. A single cycle of alemtuzumab, administered over 5 days, depletes lymphocytes. Reconstitution causes prolonged alterations in the lymphocyte repertoire, with relatively increased regulatory T-cell numbers and reduced naïve T cells. It is currently approved for the treatment of B-cell chronic lymphocytic leukemia and is being considered for licensing for multiple sclerosis (MS).When first used, alemtuzumab successfully reduced relapses and new lesion formation based on magnetic resonance imaging in people with progressive MS, but this cohort continued to accumulate disability, associated with progressive cerebral atrophy, presumably due to axonal degeneration. From this experience, we advocated that immunotherapies should be given early in the course of the disease. Since then, one phase II and two phase III trials have shown that alemtuzumab reduces the relapse rate, compared with the active comparator interferon beta-1a (IFNβ-1a), in treatment-naïve and treatment-experienced MS up to 10 years from disease onset. Furthermore, in two of these trials, alemtuzumab reduced the risk of accumulating disability compared with IFNβ-1a; indeed alemtuzumab treatment led to an improvement in disability and reduction in cerebral atrophy. Safety issues are infusion-associated reactions, mainly controlled by methyl-prednisolone, antihistamines, and antipyretics; mild to moderate infections; and autoimmunity. After 5 years, 30 to 40% of alemtuzumab patients have developed autoimmunity, largely against the thyroid gland, but rarely (2%) against platelets in immune thrombocytopenia, and in a few cases, Goodpasture's renal syndrome.Alemtuzumab is an effective therapy for early relapsing-remitting multiple sclerosis, offering disability improvement at least to 5 years after treatment. Its use requires careful monitoring so that potentially serious side effects can be treated early and effectively.

    Full Text Available Background/Aim. There are almost no studies on apraxia in people with multiple sclerosis. Although the white matter is damaged in MS, it is not the only location in which the pathological changes are present. Demyelinated lesions in the cortex have recently been recognized as important components of multiple sclerosis pathology. The aim of this study was to determine whether apraxia is present among people with MS, and the importance of demographic characteristics and impairment of functional systems at conceptualization and execution of movements. Methods. The experimental group consisted of 30 patients, mean age 51.34 ± 7.70 years. The patients in the experimental group were diagnosed with MS according to the McDonald criteria. The control group consisted of 30 healthy subjects, mean age 50.30 ± 10.47 years. For research purposes, we used the following instruments: Questionnaire for Collecting Demographic Data, Kurtzke Functional Systems Scores, Waterloo-Sunnybrook Apraxia Battery (WatAB. Execution of motion tasks that are a part of the Watwere incorporated in the System for the Observation and Analysis of Motor Behavior. Results. Our study showed that limb apraxia was common in people with MS. Apraxia was present during pantomime in 26.70% of the patients, and during the imitation of movements in 44.80% of the patients. Gender, age, education level, duration of disease and a form of MS did not determine the quality of conceptualization and execution of movements. The time elapsed from the last exacerbation was a determinant of quality of executed movements. Impairments of functional systems predicted impairments of movement execution. The expanded disability scale score correlated with the severity of apraxia. Conclusion. Our study confirm the presence of apraxia in MS. It is necessary to carry out further studies using functional magnetic resonance imaging, as well as the conduct longitudinal studies to determine the precise structure of

    High-throughput technologies have led to advances in the recognition of disease pathways and their underlying mechanisms. To investigate the impact of micro-RNAs on the disease process in multiple sclerosis, a prototypic inflammatory neurological disorder, we examined cerebral white matter from patients with or without the disease by micro-RNA profiling, together with confirmatory reverse transcription–polymerase chain reaction analysis, immunoblotting and gas chromatography-mass spectrometry. These observations were verified using the in vivo multiple sclerosis model, experimental autoimmune encephalomyelitis. Brains of patients with or without multiple sclerosis demonstrated differential expression of multiple micro-RNAs, but expression of three neurosteroid synthesis enzyme-specific micro-RNAs (miR-338, miR-155 and miR-491) showed a bias towards induction in patients with multiple sclerosis (P micro-RNAs revealed suppression of enzyme transcript and protein levels in the white matter of patients with multiple sclerosis (P micro-RNA target knockdown experiments (P micro-RNAs by in situ hybridization in the brains of patients with or without multiple sclerosis. Levels of important neurosteroids, including allopregnanolone, were suppressed in the white matter of patients with multiple sclerosis (P micro-RNAs, miR-338 and miR-155, accompanied by diminished expression of neurosteroidogenic enzymes and allopregnanolone, was also observed in the brains of mice with experimental autoimmune encephalomyelitis (P < 0.05). Allopregnanolone treatment of the experimental autoimmune encephalomyelitis mouse model limited the associated neuropathology, including neuroinflammation, myelin and axonal injury and reduced neurobehavioral deficits (P < 0.05). These multi-platform studies point to impaired neurosteroidogenesis in both multiple sclerosis and experimental autoimmune encephalomyelitis. The findings also indicate that allopregnanolone and perhaps other neurosteroid

    The causes of incomplete remyelination in progressive multiple sclerosis are unknown, as are the pathological correlates of the different clinical characteristics of patients with primary and secondary progressive disease. We analysed brains and spinal cords from 51 patients with progressive multiple sclerosis by planimetry. Thirteen patients with primary progressive disease were compared with 34 with secondary progressive disease. In patients with secondary progressive multiple sclerosis, we found larger brain plaques, more demyelination in total and higher brain loads of active demyelination compared with patients with primary progressive disease. In addition, the brain density of plaques with high-grade inflammation and active demyelination was highest in secondary progressive multiple sclerosis and remained ~18% higher than in primary progressive multiple sclerosis after adjustments for other plaque types and plaque number (Pprogressive multiple sclerosis. By contrast, there were no group differences in the brain load or frequency of low-grade inflammatory plaques with slowly expanding demyelination. Spinal cord lesion loads and remyelination capacity were also comparable in the two patient groups. Remyelinated areas were more vulnerable than the normal-appearing white matter to new demyelination, including active demyelination in secondary progressive multiple sclerosis. 'Recurrent' slowly expanding demyelination, affecting remyelinated areas, and the load of slowly expanding demyelination correlated with incomplete remyelination in both groups. In turn, incomplete remyelination in the spinal cord correlated with higher disease-related disability (determined retrospectively; r = -0.53; Pprogressive multiple sclerosis. These patients may, thereby, be spared symptoms until the spinal cord is affected. By contrast, recurrent active demyelination of repaired myelin could explain why similar symptoms often develop in consecutive relapses in relapsing

    The last twelve years have witnessed the development of new therapies for relapsing-remitting multiple sclerosis that demonstrate increased efficacy relative to previous therapies. Many of these new drugs target the inflammatory phase of disease by manipulating different aspects of the immune system. While these new treatments are promising, the development of therapies for patients with progressive multiple sclerosis remains a significant challenge. We discuss the distinct mechanisms that may contribute to these two types of multiple sclerosis and the implications of these differences in the development of new therapeutic targets for this debilitating disease.

    The use of magnetic resonance imaging (MRI) in patients with multiple sclerosis has markedly increased in recent years. The main task of the MRI studies after the diagnosis of multiple sclerosis is to assess the dynamics of MRI for determining disease progression and monitoring the efficacy of therapy. In this regard, it is very important to obtain the most identical baseline and follow-up MRI that is possible when a single standard protocol is used. This article presents the protocol of brain MRI and spinal cord MRI and interpretation of MRI studies in patients with multiple sclerosis.

Previously, we presented evidence of platelet activation in a small cohort of treatment-naive MS patients. Methods In this report, 92 normal controls and 33 stable, untreated MS patients were studied. Platelet counts, measures of platelet activation [plasma platelet microparticles (PMP, P-selectin expression (CD62p, circulating platelet microaggragtes (PAg], as well as platelet-associated IgG/IgM, were carried out. In addition, plasma protein S activity was measured. Results Compared to controls, PMP were significantly elevated in MS (p Conclusion Platelets are significantly activated in MS patients. The mechanisms underlying this activation and its significance to MS are unknown. Additional study of platelet activation and function in MS patients is warranted.

    Multiple sclerosis (MS) is a chronic inflammatory demyelinating disorder of the central nervous system characterized by episodic and progressive neurologic dysfunction resulting from inflammatory and autoimmune reactions.The underlying pathogenesis of MS remains largely unclear.However,it is currently accepted as a T cell-mediated autoimmune disease.Among other clinical manifestations,sexual dysfunction (SD) is a painful but still underreported and underdiagnosed symptom of the disorder.SD in MS patients may result from a complex set of conditions and may be associated with multiple anatomic,physiologic,biologic,medical and psychological factors.SD arises primarily from lesions affecting the neural pathways involved in physiologic function.In addition,psychological factors,the side effects of medications and physical symptoms such as fatigue,muscular weakness,menstrual changes,pain and concerns about bladder and bowel incontinence may also be involved.Since MS primarily affects young people,SD secondary to MS may have a great impact on quality of life.Thus,maintaining a healthy sexual life with MS is an important priority.The treatment of SD requires multidisciplinary teamwork and cooperation among specialists,individual patients,partners and the society.

    OBJECTIVE: To compare the suicide risk among Danish citizens with multiple sclerosis with that of the general population, and to evaluate changes over 45 years. METHODS: The study was based on linkage of the Danish Multiple Sclerosis Registry to the Cause of Death Registry. It comprised all 10...... taken their own lives, whereas the expected number of suicides was 54.2 (29.1 men, 25.1 women). Thus the suicide risk among persons with multiple sclerosis was more than twice that of the general population (SMR = 2.12). The increased risk was particularly high during the first year after diagnosis (SMR...... = 3.15). CONCLUSIONS: The risk of suicide in multiple sclerosis was almost twice as high as expected more than 20 years after diagnosis. The excess suicide risk has not declined since 1953....

    2015-01-01

    Visual impairment is a key manifestation of multiple sclerosis. Acute optic neuritis is a common, often presenting manifestation, but visual deficits and structural loss of retinal axonal and neuronal integrity can occur even without a history of optic neuritis. Interest in vision in multiple sclerosis is growing, partially in response to the development of sensitive visual function tests, structural markers such as optical coherence tomography and magnetic resonance imaging, and quality of life measures that give clinical meaning to the structure-function correlations that are unique to the afferent visual pathway. Abnormal eye movements also are common in multiple sclerosis, but quantitative assessment methods that can be applied in practice and clinical trials are not readily available. We summarize here a comprehensive literature search and the discussion at a recent international meeting of investigators involved in the development and study of visual outcomes in multiple sclerosis, which had, as its overriding goals, to review the state of the field and identify areas for future research. We review data and principles to help us understand the importance of vision as a model for outcomes assessment in clinical practice and therapeutic trials in multiple sclerosis.

    Full Text Available INTRODUCTION Fatty acids have an important role in structure and function of the nervous system. Recently, epidemiologic studies on neurodegenerative disorders have evaluated the usefulness of polyunsaturated fatty acids on multiple sclerosis. OBJECTIVE To examine recent studies, clinical trials, and reviews on the therapeutic effect of polyunsaturated fatty acids in multiple sclerosis. METHODS We conducted a search in MEDLINE/PubMed and Cochrane Library with the terms "fatty acids", "omega-3" and "omega-6" in combination with "multiple sclerosis". Articles were selected according to their relevance on the topic. RESULTS Epidemiologic studies have shown benefits of dietary supplementation with polyunsaturated fatty acids -especially omega-3- in relation to inflammatory, autoimmune and neurodegenerative disorders. In contrast, the studies do not show a beneficial effect of polyunsaturated fatty acids in multiple sclerosis. However, there are limitations related to design and sample issues in these studies CONCLUSIONS There is some evidence of a protective effect of polyunsaturated fatty acids on the risk of multiple sclerosis. Despite this, to date controlled trials have not produced definite results on the benefits of supplementation with polyunsaturated fatty acids in patients with multiple sclerosis. Any potential benefit will have to be confirmed in the long term.

    While current immunomodulating drugs aim to reduce multiple sclerosis (MS) exacerbations and slow disease progression, rehabilitation aims to improve and maintain the functional abilities of patients in the face of disease progression. An increasing number of journal articles are describing the value of the many rehabilitation interventions that can be used throughout the course of the disease, from the initial symptoms to the advanced stages. An integrated team of healthcare professionals is necessary to address a myriad of problems to reduce impairments, disabilities, and handicaps. The problems may be related to fatigue, weakness, spasticity, mobility, balance, pain, cognition, mood, relationships, bowel, bladder, sexual function, swallowing, speech, transportation, employment, recreation, and activities of daily living (ADL) such as dressing, eating, bathing, and household chores. The team can help prevent complications and secondary disabilities, while increasing patient safety. Improving neurologically related function, maintaining good relationships, and feeling productive and creative adds enormously to the quality of life of people with MS and their families. Rehabilitation is more than an 'extra' service that is given after medical therapies; it is an integral part of the management of the diverse set of problems encountered throughout the course of the disease. An interdisciplinary team may have many members, including physicians, nurses, physical therapists, occupational therapists, speech and language pathologists, psychotherapists, social workers, recreational therapists, vocational rehabilitation therapists, patients, families, and other caregivers.

    2007-11-15

    The primary pathogenetic mechanism responsible for the distinctive demyelinating lesions in the Central Nervous System (CNS) in Multiple Sclerosis (MS), first described in remarkable detail by Charcot more than 170 years ago, remains one of the most baffling conundrums in medicine. A possible role for bacterial cell molecules and transportable proteins in the pathogenesis of MS is reviewed. The ability of bacterial toxins to distort immunity and to cause distinctive toxic damage in the nervous system is discussed in the light of largely forgotten data linking bacterial nasopharyngeal infections with optic neuritis, optochiasmatic arachnoiditis and MS. While the blood-brain barrier substantially protects the CNS from hematogenous toxins, there is a route by which the barrier may be by-passed. Data is reviewed which shows that the CSF and extra-cellular fluid circulation is bi-directionally linked to the lymphatic drainage channels of the nasopharyngeal mucosa. While this provides a facility by which the CNS may mount immunological responses to antigenic challenges from within, it is also a route by which products of nasopharyngeal infection may drain into the CNS and be processed by the immune cells of the meninges and Virchow-Robin perivascular spaces. If potentially toxic bacterial products are identified in early MS tissues at these sites, this would provide an entirely new insight into the pathogenetic mechanisms of this frustratingly enigmatic disease.

  6. Remyelination Therapy in Multiple Sclerosis

    Directory of Open Access Journals (Sweden)

    Danielle E. Harlow

    2015-12-01

    Full Text Available Multiple Sclerosis (MS is an immune-mediated disorder of the central nervous system that results in destruction of the myelin sheath that surrounds axons and eventual neurodegeneration. Current treatments approved for the treatment of relapsing forms of MS target the aberrant immune response and successfully reduce the severity of attacks and frequency of relapses. Therapies are still needed that can repair damage particularly for the treatment of progressive forms of MS for which current therapies are relatively ineffective. Remyelination can restore neuronal function and prevent further neuronal loss and clinical disability. Recent advancements in our understanding of the molecular and cellular mechanisms regulating myelination, as well as the development of high throughput screens to identify agents that enhance myelination, have lead to the identification of many potential remyelination therapies currently in pre-clinical and early clinical development. One problem that has plagued the development of treatments to promote remyelination is the difficulty in assessing remyelination in patients with current imaging techniques. Powerful new imaging technologies are making it easier to discern remyelination in patients, which is critical for the assessment of these new therapeutic strategies during clinical trials. This review will summarize what is currently known about remyelination failure in MS, strategies to overcome this failure, new therapeutic treatments in the pipeline for promoting remyelination in MS patients, and new imaging technologies for measuring remyelination in patients.

  7. Islamic fasting and multiple sclerosis

    Science.gov (United States)

    2014-01-01

    Background Month-long daytime Ramadan fasting pose s major challenges to multiple sclerosis (MS) patients in Muslim countries. Physicians should have practical knowledge on the implications of fasting on MS. We present a summary of database searches (Cochrane Database of Systematic Reviews, PubMed) and a mini-symposium on Ramadan fasting and MS. In this symposium, we aimed to review the effect of fasting on MS and suggest practical guidelines on management. Discussion In general, fasting is possible for most stable patients. Appropriate amendment of drug regimens, careful monitoring of symptoms, as well as providing patients with available evidence on fasting and MS are important parts of management. Evidence from experimental studies suggests that calorie restriction before disease induction reduces inflammation and subsequent demyelination and attenuates disease severity. Fasting does not appear to have unfavorable effects on disease course in patients with mild disability (Expanded Disability Status Scale (EDSS) score ≤3). Most experts believed that during fasting (especially in summer), some MS symptoms (fatigue, fatigue perception, dizziness, spasticity, cognitive problems, weakness, vision, balance, gait) might worsen but return to normal levels during feasting. There was a general consensus that fasting is not safe for patients: on high doses of anti-convulsants, anti-spastics, and corticosteroids; with coagulopathy or active disease; during attacks; with EDSS score ≥7. Summary These data suggest that MS patients should have tailored care. Fasting in MS patients is a challenge that is directly associated with the spiritual belief of the patient. PMID:24655543

    The development of new disease-modifying drugs (DMD) in relapsing-remitting multiple sclerosis (RRMS), which share the common denominator of oral administration, considerably improves patient expectations in terms of effectiveness, tolerability and treatment adherence compared with currently available drugs. However, the common route of administration of these drugs does not mean that they are equivalent, since the heading of "oral route" encompasses drugs with distinct indications and mechanisms of action, as well as heterogeneous results in terms of efficacy and safety, allowing treatment to be personalized according to the each patient' s characteristics. Currently, four oral DMD are available or in an advanced stage of clinical development: fingolimod, teriflunomide, dimethyl fumarate and laquinimod. In pivotal trials versus placebo, these molecules reduced the annualized rate of exacerbations versus placebo by 54%, 31%, 53% and 23%, respectively, the risk of progression of disability by 31%, 30%, 38% and 36%, and the number of active lesions showing contrast uptake on magnetic resonance imaging by 82%, 80%, 90% and 37%, respectively. Based on the risk/benefit ratio, fingolimod is indicated in patients with suboptimal response to initial DMD or in severe rapidly progressing RRMS, while the remaining drugs can be used as first-line options. Clinical experience with these treatments will provide new data on safety and effectiveness, which will be determinant when establishing therapeutic algorithms.

  9. Neuroendocrine Immunoregulation in Multiple Sclerosis

    Directory of Open Access Journals (Sweden)

    Nathalie Deckx

    2013-01-01

    Full Text Available Currently, it is generally accepted that multiple sclerosis (MS is a complex multifactorial disease involving genetic and environmental factors affecting the autoreactive immune responses that lead to damage of myelin. In this respect, intrinsic or extrinsic factors such as emotional, psychological, traumatic, or inflammatory stress as well as a variety of other lifestyle interventions can influence the neuroendocrine system. On its turn, it has been demonstrated that the neuroendocrine system has immunomodulatory potential. Moreover, the neuroendocrine and immune systems communicate bidirectionally via shared receptors and shared messenger molecules, variously called hormones, neurotransmitters, or cytokines. Discrepancies at any level can therefore lead to changes in susceptibility and to severity of several autoimmune and inflammatory diseases. Here we provide an overview of the complex system of crosstalk between the neuroendocrine and immune system as well as reported dysfunctions involved in the pathogenesis of autoimmunity, including MS. Finally, possible strategies to intervene with the neuroendocrine-immune system for MS patient management will be discussed. Ultimately, a better understanding of the interactions between the neuroendocrine system and the immune system can open up new therapeutic approaches for the treatment of MS as well as other autoimmune diseases.

  10. Natalizumab therapy of multiple sclerosis.

    Hutchinson, Michael

    2012-02-01

    Multiple sclerosis (MS) is the commonest disabling neurological disease of young and middle-aged adults affecting 1 million persons world wide. The illness begins with a relapsing-remitting MS course in 85%-90% of patients; the other 10%-15% have a primary progressive onset MS. Our current understanding is that MS is an autoimmune disorder with an inflammatory T-cell attack on myelin or some component of the oligodendrocyte--myelin structure. Relapses of disease activity result in plaques of demyelination with destruction of myelin and, to a lesser, extent axons. Lymphocytes within the central nervous system tissue recruit more cells leading to an inflammatory cascade that causes myelin damage, axonal disruption, and neuronal death. If the plaque occurs in a vocal area of the central nervous system then symptoms relating to that area result. However, magnetic resonance imaging shows that approximately 10 times more lesions occur in asymptomatic areas of the brain. Recovery from an initial relapse may appear relatively complete but persistent inflammation results in axonal injury and residual disability results. With time and accumulated lesion load, secondary degeneration of denuded axons results in the phase of secondary progressive MS usually 15-20 years after onset.

    Full Text Available OBJECTIVE: To describe the epidemiological and clinical characteristics of Venezuelan pediatric patients with multiple sclerosis (MS. METHODS: Database records from the National Program for MS were searched for patients with an established diagnosis of MS whose first symptoms appeared before age 18. RESULTS: The national database held records of 1.710 patients; 3.8% had onset of the first symptoms before age 18. 46.7% were boys, yielding an F:M ratio of 1.13:1. Many children had a disease onset characterized by motor impairment (30.7%, brainstem/cerebellum and spinal cord affectation (27.6%, headache (26%. Less frequent symptoms were sensory symptoms (8% and optic neuritis (7%. DISCUSSION: Pediatric MS patients in Venezuela represent a significant proportion of all MS cases. The clinical pattern is characterized by motor symptoms at onset, and predominantly monosymptomatic presentation with a relapsing-remitting pattern. This is the first systematic attempt to estimate the prevalence of pediatric MS in Venezuela.

  12. Iron Chelation and Multiple Sclerosis

    2014-01-01

    Full Text Available Histochemical and MRI studies have demonstrated that MS (multiple sclerosis patients have abnormal deposition of iron in both gray and white matter structures. Data is emerging indicating that this iron could partake in pathogenesis by various mechanisms, e.g., promoting the production of reactive oxygen species and enhancing the production of proinflammatory cytokines. Iron chelation therapy could be a viable strategy to block iron-related pathological events or it can confer cellular protection by stabilizing hypoxia inducible factor 1α, a transcription factor that normally responds to hypoxic conditions. Iron chelation has been shown to protect against disease progression and/or limit iron accumulation in some neurological disorders or their experimental models. Data from studies that administered a chelator to animals with experimental autoimmune encephalomyelitis, a model of MS, support the rationale for examining this treatment approach in MS. Preliminary clinical studies have been performed in MS patients using deferoxamine. Although some side effects were observed, the large majority of patients were able to tolerate the arduous administration regimen, i.e., 6–8 h of subcutaneous infusion, and all side effects resolved upon discontinuation of treatment. Importantly, these preliminary studies did not identify a disqualifying event for this experimental approach. More recently developed chelators, deferasirox and deferiprone, are more desirable for possible use in MS given their oral administration, and importantly, deferiprone can cross the blood–brain barrier. However, experiences from other conditions indicate that the potential for adverse events during chelation therapy necessitates close patient monitoring and a carefully considered administration regimen.

  13. Alemtuzumab therapy for multiple sclerosis.

    Coles, Alasdair J

    2013-01-01

    Alemtuzumab is a humanized monoclonal antibody that is administered daily for 5 days, and then no further therapy is required for 12 months. It causes rapid and prolonged lymphocyte depletion; the consequent homeostatic reconstitution leads to a radically reformed lymphocyte pool with a relative increase in regulatory T cells and expansion of autoreactive T cells. Although previously licensed for the treatment of B-cell chronic lymphocytic leukemia, it is now been considered for licensing in the treatment of multiple sclerosis (MS). From a disappointing experience with alemtuzumab in progressive MS, Alastair Compston and I argued that immunotherapies should be given early in the course of the disease. In a unique program of drug development in MS, alemtuzumab has been compared in 1 phase 2 trial and 2 phase 3 trials with the active comparator interferon beta-1a. In all trials, alemtuzumab was more effective in suppressing relapses than interferon beta-1a. In one phase 2 and one phase 3 trial, alemtuzumab also reduced the risk of accumulating disability compared with interferon beta-1a. Indeed, alemtuzumab treatment led to an improvement in disability and a reduction in cerebral atrophy. The safety issues are infusion-associated reactions largely controlled by methylprednisolone, antihistamines, and antipyretics; mild-to-moderate infections (with 3 opportunistic infections from the open-label experience: 1 case each of spirochaetal gingivitis, pyogenic granuloma, and Listeria meningitis); and autoimmunity. Usually autoimmunity is directed against the thyroid gland, but causes (1 %) immune thrombocytopenia, and in a few cases antiglomerular basement membrane syndrome. Alemtuzumab is an effective therapy for early relapsing-remitting MS, offering disability improvement at least to 5 years after treatment. Its use requires careful monitoring so that potentially serious side effects can be treated early and effectively.

  14. Nutrition Facts in Multiple Sclerosis

    Directory of Open Access Journals (Sweden)

    Paolo Riccio

    2015-02-01

    Full Text Available The question whether dietary habits and lifestyle have influence on the course of multiple sclerosis (MS is still a matter of debate, and at present, MS therapy is not associated with any information on diet and lifestyle. Here we show that dietary factors and lifestyle may exacerbate or ameliorate MS symptoms by modulating the inflammatory status of the disease both in relapsing-remitting MS and in primary-progressive MS. This is achieved by controlling both the metabolic and inflammatory pathways in the human cell and the composition of commensal gut microbiota. What increases inflammation are hypercaloric Western-style diets, characterized by high salt, animal fat, red meat, sugar-sweetened drinks, fried food, low fiber, and lack of physical exercise. The persistence of this type of diet upregulates the metabolism of human cells toward biosynthetic pathways including those of proinflammatory molecules and also leads to a dysbiotic gut microbiota, alteration of intestinal immunity, and low-grade systemic inflammation. Conversely, exercise and low-calorie diets based on the assumption of vegetables, fruit, legumes, fish, prebiotics, and probiotics act on nuclear receptors and enzymes that upregulate oxidative metabolism, downregulate the synthesis of proinflammatory molecules, and restore or maintain a healthy symbiotic gut microbiota. Now that we know the molecular mechanisms by which dietary factors and exercise affect the inflammatory status in MS, we can expect that a nutritional intervention with anti-inflammatory food and dietary supplements can alleviate possible side effects of immune-modulatory drugs and the symptoms of chronic fatigue syndrome and thus favor patient wellness.

  15. Environmental factors in multiple sclerosis.

    Pantazou, Vasiliki; Schluep, Myriam; Du Pasquier, Renaud

    2015-04-01

    Although multiple sclerosis (MS) is recognized as a disorder involving the immune system, the interplay of environmental factors and individual genetic susceptibility seems to influence MS onset and clinical expression, as well as therapeutic responsiveness. Multiple human epidemiological and animal model studies have evaluated the effect of different environmental factors, such as viral infections, vitamin intake, sun exposure, or still dietary and life habits on MS prevalence. Previous Epstein-Barr virus infection, especially if this infection occurs in late childhood, and lack of vitamin D (VitD) currently appear to be the most robust environmental factors for the risk of MS, at least from an epidemiological standpoint. Ultraviolet radiation (UVR) activates VitD production but there are also some elements supporting the fact that insufficient UVR exposure during childhood may represent a VitD-independent risk factor of MS development, as well as negative effect on the clinical and radiological course of MS. Recently, there has been a growing interest in the gut-brain axis, a bidirectional neuro-hormonal communication system between the intestinal microbiota and the central nervous system (CNS). Indeed, components of the intestinal microbiota may be pro-inflammatory, promote the migration of immune cells into the CNS, and thus be a key parameter for the development of autoimmune disorders such as MS. Interestingly most environmental factors seem to play a role during childhood. Thus, if childhood is the most fragile period to develop MS later in life, preventive measures should be applied early in life. For example, adopting a diet enriched in VitD, playing outdoor and avoiding passive smoking would be extremely simple measures of primary prevention for public health strategies. However, these hypotheses need to be confirmed by prospective evaluations, which are obviously difficult to conduct. In addition, it remains to be determined whether and how Vit

    Full Text Available Multiple sclerosis (MS is a chronic inflammatory and demyelinating disease of autoimmune originate. The main agents responsible for the MS development include exogenous, environmental, and genetic factors. MS is characterized by multifocal and temporally scattered central nervous system (CNS damage which lead to the axonal damage. Among clinical courses of MS it can be distinguish relapsing-remitting multiple sclerosis (RRMS, secondary progressive multiple sclerosis (SPSM, primary progressive multiple sclerosis (PPMS, and progressive-relapsing multiple sclerosis (RPMS. Depending on the severity of signs and symptoms MS can be described as benign MS or malignant MS. MS diagnosis is based on McDonald’s diagnostic criteria, which link clinical manifestation with characteristic lesions demonstrated by magnetic resonance imaging (MRI, cerebrospinal fluid (CSF analysis, and visual evoked potentials. Among CSF laboratory tests used to the MS diagnosis are applied: Tibbling & Link IgG index, reinbegrams, and CSF isoelectrofocusing for oligoclonal bands detection. It should be emphasized, that despite huge progress regarding MS as well as the availability of differentdiagnostics methods this disease is still a diagnostic challenge. It may result from fact that MS has diverse clinical course and there is a lack of single test, which would be of appropriate diagnostic sensitivity and specificity for quick and accurate diagnosis.

    Full Text Available Fundament: The proteolitic rupture of the extracellular matrix due to metalloproteinase 2 and 9 is one of the aspects that can influence in the alteration of the permeability of the blood-brain barrier (BBB in multiple sclerosis. Objective: To determine metalloproteinase activity with gelatinous activity in patients suffering from multiple sclerosis. Methods: the cerebrospinal fluid (CSF samples taken from 31 patients suffering from multiple sclerosis and a control group formed by 21 patients without neurological disease. The metalloproteinase 2 and 9 activities in the cerebrospinal fluid were determined by zimográfica technique through polyacrylamide gel electrophoresis. The bands were later analysed by their molecular weight and the relative metalloproteinase 9 activity was calculated. Total protein concentrations, albumin and immunoglobulin G (IgG, the IgG rate and the Q rate were assessed to evaluate the IgG intrathecal and the functional state of the blood-brain barrier. Results: metalloproteinase 2 activity was detected in the cerebrospinal fluid of all patients and control group. Metalloproteinase 9 activity was only found in the 61.3 % of the patients. The presence of relative metalloproteinase 9 activity was neither associated with the clinical variables nor the laboratory ones. An association was found between its presence and the oligoclonal bands in patients with multiple sclerosis. In those patients under immunomodular treatment it was presented with less frequency. Conclusions: There is a possible participation of Metalloproteinase 9 in the immunopathological mechanisms of the multiple sclerosis.

    Directory of Open Access Journals (Sweden)

    Vit Zikan

    2011-01-01

    Full Text Available Multiple sclerosis (MS is a gait disorder characterized by acute episodes of neurological defects leading to progressive disability. Patients with MS have multiple risk factors for osteoporotic fractures, such as progressive immobilization, long-term glucocorticoids (GCs treatment or vitamin D deficiency. The duration of motor disability appears to be a major contributor to the reduction of bone strength. The long term immobilization causes a marked imbalance between bone formation and resorption with depressed bone formation and a marked disruption of mechanosensory network of tightly connected osteocytes due to increase of osteocyte apoptosis. Patients with higher level of disability have also higher risk of falls that combined with a bone loss increases the frequency of bone fractures. There are currently no recommendations how to best prevent and treat osteoporosis in patients with MS. However, devastating effect of immobilization on the skeleton in patients with MS underscores the importance of adequate mechanical stimuli for maintaining the bone structure and its mechanical competence. The physical as well as pharmacological interventions which can counteract the bone remodeling imbalance, particularly osteocyte apoptosis, will be promising for prevention and treatment of osteoporosis in patients with MS.

    The mechanisms underlying the pathogenesis of multiple sclerosis induce the changes that underpin relapse-associated and progressive disability. Disease mechanisms can be investigated in preclinical models and patients with multiple sclerosis by molecular and metabolic imaging techniques. Many insights have been gained from such imaging studies: persisting inflammation in the absence of a damaged blood-brain barrier, activated microglia within and beyond lesions, increased mitochondrial activity after acute lesions, raised sodium concentrations in the brain, increased glutamate in acute lesions and normal-appearing white matter, different degrees of demyelination in different patients and lesions, early neuronal damage in grey matter, and early astrocytic proliferation and activation in lesions and white matter. Clinical translation of molecular and metabolic imaging and extension of these techniques will enable the assessment of novel drugs targeted at these disease mechanisms, and have the potential to improve health outcomes through the stratification of patients for treatments.

    Full Text Available With the introduction of interferon-β1b in 1993 as the first FDA-approved treatment for multiple sclerosis, the era of treatment of this incurable disease began, and its natural course was permanently changed. Currently, seven different treatments for patients with multiple sclerosis with different mechanisms of action and dissimilar side effect profiles exist. These medications include interferon-β1a intramuscular (Avonex, interferon-β1a subcutaneous (Rebif, interferon-β1b subcutaneous (Betaseron/Extavia, glatiramer acetate (Copaxone, natalizumab (Tysabri, fingolimod (Gilenya, teriflunomide (Aubagio, and mitoxantrone (Novantrone. In addition, a large number of clinical trials are being conducted to assess the safety and efficacy of various experimental agents in patients with multiple sclerosis, including alemtuzumab, dimethyl fumarate, laquinimod, rituximab, daclizumab, and cladribine. In this paper, the author presents a concise and comprehensive review of present and potential treatments for this incurable disease.

    Chlamydia and antibodies to them were detected by serological, molecular biological, and culture methods in the sera and cerebrospinal fluid of patients with multiple sclerosis and in the reference groups of subjects without neurological diseases. Correlations between the agent presence in the biological fluids of patients and clinical characteristics of the disease were analyzed. C. pneumoniae were more incident in the biological liquids of patients with multiple sclerosis than in healthy volunteers. On the other hand, the incidence of the agent in the patients was not high and its presence did not correlate with the clinical manifestations. C. trachomatis was equally rare in the patients and volunteers. The studies indicated the existence of a group of patients infected by C. pneumoniae in the cohort of patients with multiple sclerosis, but the impact of this agent for the disease course remains unclear.

    Integrins are the foremost family of cell adhesion molecules that regulate immune cell trafficking in health and diseases. Integrin alpha4 mediates organ-specific migration of immune cells to the inflamed brain, thereby playing the critical role in the pathogenesis of multiple sclerosis. Anti-alpha4 integrin therapy aiming to block infiltration of autoreactive lymphocytes to the inflamed brain has been validated in several clinical trials for the treatment of multiple sclerosis. This paper provides readers with an overview of the molecular and structural bases of integrin activation as well as rationale for using anti-alpha4 integrin therapy for multiple sclerosis and then chronicles the rise and fall of this treatment strategy using natalizumab, a humanized anti-alpha4 integrin.

  7. Interplay between mechanisms of damage and repair in multiple sclerosis.

    Science.gov (United States)

    Stadelmann, Christine; Brück, Wolfgang

    2008-03-01

    The neuropathology of multiple sclerosis is characterised by focal damage to white matter. However, tissue damage is also present in the cortical grey matter, with a particularly high prevalence of cortical demyelination being observed in secondary progressive and primary progressive forms of the disease. The presence of meningeal B-cell follicle-like structures, which frequently appear during the secondary progressive phase of disease, may be involved in the formation of these subpial cortical lesions. Diffuse white matter inflammation accompanied by axonal damage can also be observed in normal appearing white matter and, again, this is more prominent in chronic progressive forms of multiple sclerosis than in acute stages of disease. Axonal damage is a particularly important component of the pathology of multiple sclerosis and appears to be a critical determinant of clinical outcome. Axons appear to become vulnerable to injury as a result of loss of their myelin sheaths. Remyelination represents an important mechanism of tissue repair in multiple sclerosis and already occurs at an early stage of lesion development and in both white and grey matter lesions. The extent of remyelination appears to be greater in cortical lesions and in lesions further from the ventricles. There is important heterogeneity between patients in terms of the extent of remyelination, which may reflect underlying differences in pathogenetic mechanisms between patients.

  8. Association of autoimmune hepatitis and multiple sclerosis: a coincidence?

    2015-09-01

    Full Text Available Autoimmune hepatitis is a chronic liver inflammation resulting from deregulation of immune tolerance mechanisms. Multiple sclerosis is also an inflammatory disease in which the insulating covers of nerve cells in the brain and spinal cord are damaged. Here we present a case of an 18 year old female with multiple sclerosis was treated with glatiramer acetate and with interferon beta 1a at our hospital. Seven months after initiating treatment, liver dysfunction occurred. Clinical and laboratory findings were suggestive of drug-induced hepatitis, which led to discontinuation of treatment with interferon. Facing a new episode of acute hepatitis one year later, she was subjected to a liver biopsy, and the analysis of autoantibodies was positive for smooth muscle antibodies. Given the diagnosis of autoimmune hepatitis she started therapy with prednisolone and azathioprine, with good clinical and analytical response. Besides, the demyelinating lesions of multiple sclerosis became lower. In conclusion, there are only a few cases that describe the association of autoimmune hepatitis with multiple sclerosis, and there is a chance both diseases have the same autoimmune inflammatory origin.

  1. Potential immunological consequences of pharmacological suppression of gastric acid production in patients with multiple sclerosis

    Directory of Open Access Journals (Sweden)

    Biswas Sangita

    2012-06-01

    Full Text Available Abstract Corticosteroids are standard treatment for patients with multiple sclerosis experiencing acute relapse. Because dyspeptic pain is a common side effect of this intervention, patients can be given a histamine receptor-2 antagonist, proton pump inhibitor or antacid to prevent or ameliorate this disturbance. Additionally, patients with multiple sclerosis may be taking these medications independent of corticosteroid treatment. Interventions for gastric disturbances can influence the activation state of the immune system, a principal mediator of pathology in multiple sclerosis. Although histamine release promotes inflammation, activation of the histamine receptor-2 can suppress a proinflammatory immune response, and blocking histamine receptor-2 with an antagonist could shift the balance more towards immune stimulation. Studies utilizing an animal model of multiple sclerosis indicate that histamine receptor-2 antagonists potentially augment disease activity in patients with multiple sclerosis. In contrast, proton pump inhibitors appear to favor immune suppression, but have not been studied in models of multiple sclerosis. Antacids, histamine receptor-2 antagonists and proton pump inhibitors also could alter the intestinal microflora, which may indirectly lead to immune stimulation. Additionally, elevated gastric pH can promote the vitamin B12 deficiency that patients with multiple sclerosis are at risk of developing. Here, we review possible roles of gastric acid inhibitors on immunopathogenic mechanisms associated with multiple sclerosis.

    Plantone, Domenico; De Angelis, Floriana; Doshi, Anisha; Chataway, Jeremy

    2016-06-01

    Secondary progressive multiple sclerosis (SPMS) is diagnosed retrospectively and involves a clinical course characterized by a progressive accumulation of neurological disability, independent of relapses, following an initial relapsing-remitting (RR) phase. Our incomplete understanding of the pathological mechanisms underlying neurodegeneration in multiple sclerosis (MS) may explain why, to date, there is no definitive imaging or laboratory test that is able to inform us when the disease is clearly entering into a progressive phase and why the vast majority of clinical trials testing immunosuppressant and immunomodulating drugs in SPMS patients has so far yielded disappointing or mixed results. Here we discuss the definition(s) of SPMS and how it may vary, outcome measurements (current and emerging) and modern trial design.

    Multiple sclerosis (MS) is an inflammatory, demyelinating disease that can affect several areas of the central nervous system. Damage along the auditory pathway can alter its integrity significantly. Therefore, it is important to investigate the auditory pathway, from the brainstem to the cortex, in individuals with MS. OBJECTIVE: The aim of this study was to characterize auditory evoked potentials in adults with MS of the remittent-recurrent type. METHOD: The study comprised 25 individuals w...

    2009-09-01

    Gray matter demyelination is frequent and extensive in most patients with multiple sclerosis (MS) and has recently received much attention in neuropathologic and imaging studies. Gray matter lesions show distinct pathologic features that make their detection difficult with conventional imaging techniques. Thus, despite their high prevalence, their impact on clinical symptoms has not been defined well so far. This review focuses on recent information from pathologic and imaging studies and summarizes our current knowledge on cortical pathology derived from human and experimental studies.

    Multiple sclerosis, an idiopathic inflammatory disease of the central nervous system, is characterized pathologically by demyelination and subsequent axonal degeneration. The disease commonly presents in young adults and affects twice as many women as men. Common presenting symptoms include numbness, weakness, visual impairment, loss of balance, dizziness, urinary bladder urgency, fatigue, and depression. The diagnosis of multiple sclerosis should be made by a physician with experience in identifying the disease. Diagnosis should be based on objective evidence of two or more neurologic signs that are localized to the brain or spinal cord and are disseminated in time and space (i.e., occur in different parts of the central nervous system at least three months apart). Magnetic resonance imaging with gadolinium contrast, especially during or following a first attack, can be helpful in providing evidence of lesions in other parts of the brain and spinal cord. A second magnetic resonance scan may be useful at least three months after the initial attack to identify new lesions and provide evidence of dissemination over time. It is critical to exclude other diseases that can mimic multiple sclerosis, including vascular disease, spinal cord compression, vitamin B12 deficiency, central nervous system infection (e.g., Lyme disease, syphilis), and other inflammatory conditions (e.g., sarcoidosis, systemic lupus erythematosus, Sjögren's syndrome). Symptom-specific drugs can relieve spasticity, bladder dysfunction, depression, and fatigue. Five disease-modifying treatments for multiple sclerosis have been approved by the U.S. Food and Drug Administration. These treatments are partially effective in reducing exacerbations and may slow progression of disability.

  14. Disease modifying therapies for relapsing multiple sclerosis.

    Multiple sclerosis (MS) is a common, disabling, putatively autoimmune neurological disease with worldwide distribution. It typically begins as a relapsing disorder that later evolves to a secondary progressive phase. Inflammatory and neurodegenerative mechanisms seem to operate in both phases, but their relative contributions and interactions are incompletely understood. Disease modifying therapies (DMTs) approved for relapsing multiple sclerosis interfere with a variety of immunological mechanisms to reduce rates of relapse, accumulation of disease burden measured by magnetic resonance imaging (MRI), and decline in neurological function over the two to three year duration of typical randomized controlled trials. Benefits of longer duration of therapy on disability are less clear, as data beyond three years are largely limited to observational studies. However, current DMTs do not slow accrual of disability once progressive multiple sclerosis is established. This review summarizes the evidence about the use of approved DMTs and examines how to individualize treatment despite the absence of validated biomarkers to guide drug selection. Methods such as stratifying patients on the basis of estimated risk for future disability, weighing patient specific factors and preferences, and using objective outcomes to adjudicate treatment success are discussed. Emerging drug therapies and strategies are also reviewed.

    The course of multiple sclerosis (MS) is influenced by sex, pregnancy and hormonal factors. To analyse the influence of the above factors in order to clarify the aetiopathogenic mechanisms involved in the disease. We conducted a comprehensive review of scientific publications in the PubMed database using a keyword search for 'multiple sclerosis', 'MS', 'EAE', 'pregnancy', 'hormonal factors', 'treatment', and related terms. We reviewed the advances presented at the meeting held by the European Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS) in March 2013 in London, as well as recommendations by international experts. We provide recommendations for counselling and treating women with MS prior to and during pregnancy and after delivery. Current findings on the effects of treatment on the mother, fetus, and newborn are also presented. We issue recommendations for future research in order to address knowledge gaps and clarify any inconsistencies in currently available data. Copyright © 2016 Sociedad Española de Neurología.

  16. The genetic aspects of multiple sclerosis

    Directory of Open Access Journals (Sweden)

    Sawcer Stephen

    2009-01-01

    Full Text Available The epidemiology of multiple sclerosis has been extensively investigated and two features have consistently emerged: marked geographical variation in prevalence and substantial familial clustering. At first sight, geographic variation would seem to imply an environmental cause for the disease, while familial clustering would seem to suggest that genetic factors have the predominant etiological effect. However, given that geographic variation in prevalence could result from variation in the frequency of genetic risk alleles and that familial clustering might result from shared environmental exposure rather than shared genetic risk alleles, it is clear that these crude inferences are unreliable. Epidemiologists have been resourceful in their attempts to resolve this apparent conflict between "nurture and nature" and have employed a whole variety of sophisticated methods to try and untangle the etiology of multiple sclerosis. The body of evidence that has emerged from these efforts has formed the foundation for decades of research seeking to identify relevant genes and this is the obvious place to start any consideration of the genetics of multiple sclerosis.

    2017-06-01

    Full Text Available Rachel Brandstadter, Ilana Katz Sand Department of Neurology, Corinne Goldsmith Dickinson Center for Multiple Sclerosis, Icahn School of Medicine at Mount Sinai, New York, NY, USA Abstract: Natalizumab is a monoclonal antibody that acts as an α4 integrin antagonist to prevent leukocyte trafficking into the central nervous system. It is US Food and Drug Administration (FDA approved for the treatment of relapsing–remitting multiple sclerosis (RRMS. Natalizumab demonstrated high efficacy in Phase III trials by reducing the annualized relapse rate, preventing multiple sclerosis (MS lesion accumulation on magnetic resonance imaging, and decreasing the probability of sustained progression of disability. The leading safety concern with natalizumab is its association with progressive multifocal leukoencephalopathy (PML, a rare brain infection typically seen only in severely immunocompromised patients caused by reactivation of the John Cunningham virus (JCV. Careful analysis of risk factors for PML in natalizumab-treated MS patients, specifically the presence of anti-JCV antibodies, has led to risk mitigation strategies to improve safety. Additional biomarkers are under investigation to further aid risk stratification. Natalizumab’s high efficacy and favorable tolerability profile have led to a broad use by MS physicians, as both first- and second-line treatments. This review discusses the natalizumab efficacy, safety, and tolerability and finishes with pragmatic considerations regarding its use in clinical practice.

    Today, the care of patients with multiple sclerosis and those around them represents a clinical and therapeutic challenge for healthcare professionals. The aim of this study is to analyse the appearance of multiple sclerosis in literature, cinema and television, and to reflect upon the image it has in these media. Several representative works that have addressed multiple sclerosis were reviewed, and many of them were seen to offer a very true-to-life vision of the disease. Likewise, a review was also conducted of the most relevant films and TV series that, on occasions, offer the general public a close look at the impact of the disease on patients or relatives, although they are sometimes somewhat exaggerated for the sake of increased dramatic effect and offer a slightly distorted view of reality. Literature largely reflects the real epidemiology, the symptoms and development of the disease, while less attention seems to be given to the diagnostic and therapeutic options open to patients. Cinema and television have offered a correct image but sometimes with the addition of more dramatic effects. It is important for literature, cinema and television to offer a realistic view of this neurological disease so as to make it better known among the public and to help lessen the stigma attached to it.

    Full Text Available BACKGROUND:To study the dimensions of fatigue in multiple sclerosis, its pathophysiology, the efficacy, tolerability and safety of drug and non-drug treatments and measurement of fatigue. METHODS: Relevant articles from PubMed and Google scholar search engines from January 1987 until September 2006 were studied to compose a short clinical update (not a systematic review and make the required clinical information available for the clinicians. RESULTS: There is evidence that fatigue is very common in all types and stages of multiple sclerosis, but its pathophysiology is not well explained. Consequently, few drug options have been offered for its treatment. Amantadine is the bestknown drug, though its efficacy and duration of action are limited. Pemoline and modafinil are alternatives and have
    some effects on fatigue. DAP (diaminopyridine, ASA (acetylsalicylic acid, methylphenidate and fluoxetine are other possible options but await further confirmation. Neurorehabilitation, regular exercise and cooling are confirmed to be of value in MS treatment. Measurement of fatigue is a complicated issue. At present fatigue does not have a laboratory marker. CONCLUSIONS: The results of this short clinical update provide guidelines for diagnosing MS-related fatigue and differentiating
    it from other similar physical and psychological conditions. It also examines prescription drug options and other therapies for MS patients with fatigue.

    There are numerous reports that people with multiple sclerosis (MS) have for many years been self-medicating with illegal street cannabis or more recently medicinal cannabis to alleviate the symptoms associated with MS and also amyotrophic lateral sclerosis (ALS). These anecdotal reports have been confirmed by data from animal models and more recently clinical trials on the ability of cannabinoids to alleviate limb spasticity, a common feature of progressive MS (and also ALS) and neurodegeneration. Experimental studies into the biology of the endocannabinoid system have revealed that cannabinoids have efficacy, not only in symptom relief but also as neuroprotective agents which may slow disease progression and thus delay the onset of symptoms. This review discusses what we now know about the endocannabinoid system as it relates to MS and ALS and also the therapeutic potential of cannabinoid therapeutics as disease-modifying or symptom control agents, as well as future therapeutic strategies including the potential for slowing disease progression in MS and ALS.

    The Genes and Environment in Multiple Sclerosis project establishes a platform to investigate the events leading to multiple sclerosis (MS) in at-risk individuals. It has recruited 2,632 first-degree relatives from across the USA. Using an integrated genetic and environmental risk score, we identified subjects with twice the MS risk when compared to the average family member, and we report an initial incidence rate in these subjects that is 30 times greater than that of sporadic MS. We discuss the feasibility of large-scale studies of asymptomatic at-risk subjects that leverage modern tools of subject recruitment to execute collaborative projects.

    Neurodegeneration is the main cause for permanent disability in multiple sclerosis. The effect of current immunomodulatory treatments on neurodegeneration is insufficient. Therefore, direct neuroprotection and myeloprotection remain an important therapeutic goal. Targeting acid-sensing ion channel 1 (encoded by the ASIC1 gene), which contributes to the excessive intracellular accumulation of injurious Na(+) and Ca(2+) and is over-expressed in acute multiple sclerosis lesions, appears to be a viable strategy to limit cellular injury that is the substrate of neurodegeneration. While blockade of ASIC1 through amiloride, a potassium sparing diuretic that is currently licensed for hypertension and congestive cardiac failure, showed neuroprotective and myeloprotective effects in experimental models of multiple sclerosis, this strategy remains untested in patients with multiple sclerosis. In this translational study, we tested the neuroprotective effects of amiloride in patients with primary progressive multiple sclerosis. First, we assessed ASIC1 expression in chronic brain lesions from post-mortem of patients with progressive multiple sclerosis to identify the target process for neuroprotection. Second, we tested the neuroprotective effect of amiloride in a cohort of 14 patients with primary progressive multiple sclerosis using magnetic resonance imaging markers of neurodegeneration as outcome measures of neuroprotection. Patients with primary progressive multiple sclerosis underwent serial magnetic resonance imaging scans before (pretreatment phase) and during (treatment phase) amiloride treatment for a period of 3 years. Whole-brain volume and tissue integrity were measured with high-resolution T(1)-weighted and diffusion tensor imaging. In chronic brain lesions of patients with progressive multiple sclerosis, we demonstrate an increased expression of ASIC1 in axons and an association with injury markers within chronic inactive lesions.

    Full Text Available Background: The aim of the study was to determine the relative frequency of abnormal urodynamic findings in new multiple sclerosis (MS cases without micturition complaints and to find its correlation with the number of MS plaques on magnetic resonance imaging (MRI, urinary tract involvement and the number of disease episodes. Methods : In this prospective study, 50 new female case of multiple sclerosis were enrolled. Age, urodynamic findings, micturition complaints and number of plaques on MRI were recorded on admission. Occurrence of urinary symptoms and number of episodes of the disease were recorded every three months during one-year follow-up. Results : The mean patients′ age was 32.4 ± 7.2 years and all patients were female. Of the 50 patients, 19 (38% had a normal urodynamic test and 31 (62% had abnormal urodynamic findings at the beginning of the study. The occurrence of micturition complaints during follow-up in patients with abnormal urodynamic findings (94% was significantly higher (p < 0.0001 than patients with normal urodynamic findings (37%. In addition, the number of plaques on MRI at the beginning of the study in patients with abnormal urodynamic finding was significantly higher (p < 0.004 compared to patients with a normal urodynamic study. The number of episodes during follow-up was not statistically different between patients with normal and abnormal urodynamic findings (p = 0.46. Conclusions : According to this study, 62% of all new MS patients had an abnormal urodynamic test. This is a considerable proportion of patients and it seems urodynamic studies can be used when MS is first diagnosed.

Methods Key words were defined as multiple sclerosis, immunomodulatory therapy and therapy, etc. We searched MEDLINE, Cochrane Library, Wanfang data bases for Scientific Journals in China and National Knowledge Infrastructure for Chinese Scientific Journals Database. Additionally, we applied manual searching and screened out conference paper and academic dissertation, etc, from various references. After that we obtained and evaluated by Jadad scales on systematic reviews, randomized controlled trials, controlled clinical trials and observational study cases about glucocorticoids, plasmapheresis, intravenous immunoglobulin, IFN-β, glatiramer acetate, mitoxantrone, natalizumab, fingolimod. Results After screening, all seventeen selected resources included systematic reviews 6 articles, randomized controlled trials 7 articles, controlled clinical trials 2 articles, observational study cases 2 articles, among which fifteen articles were proved to be high quality (according to Jadad scoring system, five score 4, six score 5, four score 7, two chapters were judged to be low quality scoring 3. Finally, we summerize that: 1 The first choice of treatment for acute relapses is glucocorticoids and we suggest that plasmapheresis or intravenous immunoglobulin may be tried as an alternative therapy in acute MS relapse, especially in case of contraindications to intravenous methylprednisolone. 2 Immunomodulatory or immunosuppressive treatment (IFN-β, glatiramer acetate, mitoxantrone, natalizumab can be an option to prevent new relapses and progression of disability. 3 Fingolimod is an oral treatment for multiple sclerosis to improve treatment adherence. Conclusion Using evidence-based medicine methods can provide us best clinical evidence on MS treatment.

    Reforms to the NHS following the passing of the Health and Social Care Act 2012 have created new purchaser organisations with responsibility for planning the configuration of healthcare services in their geographic areas. If a community multiple sclerosis (MS) nursing service is to survive in this environment, it must demonstrate its ability to contribute to achieving the purchaser organisations' objectives. Evaluation data, such as hospital admission avoidance and patient satisfaction, will be crucial in demonstrating the community MS nursing service's clinical and economic effectiveness. A strengths, weaknesses, opportunities and threats (SWOT) analysis of the issues facing a community MS service in this environment is provided.

    Full Text Available BACKGROUND: Multiple sclerosis (MS preferentially affects females at childbearing age. For this reason patients and treating physicians were frequently confronted with questions concerning family planning, pregnancy and birth. OBJECTIVE: The aim of this study was to evaluate the expertise about pregnancy related topics in multiple sclerosis of neurologists in private practice. METHODS: We developed a survey with 16 multiple choice questions about pregnancy related topics and sent it to neurologists in private practice in Berlin, Germany. RESULTS: 56 completed questionnaires were sent back. 54% of all questions were answered correctly, 21% of the questions were answered with "I don't know". Correct answers were more often given by physicians who treat more than 400 MS patients per year (p = 0.001. Further positive associations were found for assumed relevance of the topic (p = 0.002 and the degree of counseling (p<0.001. CONCLUSION: To provide a comprehensive counseling, MS patients with desire for children should be counseled by physicians with a lot of experience in MS treatment.

    Objective: To examine dermatoglyphic features to clarify implicated genetic predisposition in the etiology of multiple sclerosis (MS). Methods: The study was conducted between January and December 2013 in the Departments of Anatomy, and Neurology, Cumhuriyet University School of Medicine, Sivas, Turkey. The dermatoglyphic data of 61 patients, and a control group consisting of 62 healthy adults obtained with a digital scanner were transferred to a computer environment. The ImageJ program was used, and atd, dat, adt angles, a-b ridge count, sample types of all fingers, and ridge counts were calculated. Results: In both hands of the patients with MS, the a-b ridge count and ridge counts in all fingers increased, and the differences in these values were statistically significant. There was also a statistically significant increase in the dat angle in both hands of the MS patients. On the contrary, there was no statistically significant difference between the groups in terms of dermal ridge samples, and the most frequent sample in both groups was the ulnar loop. Conclusions: Aberrations in the distribution of dermatoglyphic samples support the genetic predisposition in MS etiology. Multiple sclerosis susceptible individuals may be determined by analyzing dermatoglyphic samples. PMID:25274586

  16. Alemtuzumab for the treatment of multiple sclerosis

    Full Text Available Mark D Willis, Neil P Robertson Institute of Psychological Medicine and Clinical Neuroscience, Cardiff University, University Hospital of Wales, Heath Park, Cardiff, UK Abstract: Alemtuzumab is an anti-CD52 monoclonal antibody, recently approved for the treatment of active, relapsing multiple sclerosis (MS. Administration of alemtuzumab causes a rapid and dramatic reduction in circulating lymphocytes, with a predictable subsequent pattern of immune reconstitution. Although the precise mode of action remains unclear, treatment results in a marked reduction in annualized relapse rates, slowing of disability progression compared with an active comparator, and may even cause disability reversal. Although conferring clear clinical benefits, alemtuzumab carries a significant long-term risk of autoimmune disease (AID, which has a particular predilection for the thyroid gland, although a wide range of other disorders have also been reported. However, risks of AID can usually be anticipated and treated successfully, provided rigorous monitoring and surveillance protocols are followed by clinicians and patients alike. Despite its immunosuppressive mechanism of action serious infections are rare and malignancies commonly associated with immunodeficiency have not been observed to date. Alemtuzumab’s unique mode of administration, as well as it’s durability of effect, provides an important addition to currently available therapeutic interventions for MS, and in particular is a valuable treatment option in recent onset and highly active relapsing disease.

    2006-01-01

    We compared the rate of fatal accidents among Danes with multiple sclerosis (MS) with that of the general population. The study was based on linkage of the Danish Multiple Sclerosis Registry to the Cause of Death Registry and covered all 10174 persons in whom MS was diagnosed during the period 1953......-1996. The end of follow-up was 1 January 1999. We calculated standardized mortality ratios (SMRs) for various types of fatal accidents. A total of 76 persons (48 men and 28 women) died from accidents, whereas the expected number of fatalities from such causes was 55.7 (31.4 men and 24.3 women). Thus, the risk...... for death from accidents among persons with MS was 37% higher than that of the general population (SMR = 1.37). We found no significant excess risk for fatal road accidents (SMR = 0.80). The risk for falls was elevated (SMR = 1.29) but not statistically significantly so. The risks were particularly high...

    Several studies have found an association between multiple sclerosis and vitamin D (VD) deficiency, which suggests that VD may play a role in the immune response. However, few studies have addressed its role in remyelination. The VD receptor and the enzymes transforming VD into metabolites which activate the VD receptor are expressed in central nervous system (CNS) cells, which suggests a potential effect of VD on the CNS. Both in vitro and animal model studies have shown that VD may play a role in myelination by acting on factors that influence the microenvironment which promotes both proliferation and differentiation of neural stem cells into oligodendrocyte progenitor cells and oligodendrocytes. It remains unknown whether the mechanisms of internalisation of VD in the CNS are synergistic with or antagonistic to the mechanisms that facilitate the entry of VD metabolites into immune cells. VD seems to play a role in the CNS and our hypothesis is that VD is involved in remyelination. Understanding the basic mechanisms of VD in myelination is necessary to manage multiple sclerosis patients with VD deficiency. Copyright © 2016 Sociedad Española de Neurología.

    Full Text Available Multiple Sclerosis (MS is a chronic inflammatory disease characterized by central nervous system (CNS demyelination and axonal degeneration. Although the cause of MS is still unknown, it is widely accepted that novel drug targets need to focus on both decreasing inflammation and promoting CNS repair. In MS and experimental autoimmune encephalomyelitis (EAE non-coding small microRNAs (miRNAs are dysregulated in the immune and central nervous systems. Since individual miRNAs are able to downregulate multiple targeted mRNA transcripts, even minor changes in miRNA expression may lead to significant alterations in post-transcriptional gene expression. Herein, we review miRNA signatures reported in CNS tissue and immune cells of MS patients and consider how altered miRNA expression may influence MS pathology.

Optical coherence tomography (OCT is a tool that is increasingly used for quantifying retinal damage in MS and other neurologic diseases. Based on spectral interferometry, it uses low-coherent infrared light to generate high-resolution spatial images of the retina. The retinal nerve fiber layer (RNFL consists of unmyelinated axons that form the optic nerve, and thus represents a part of the central nervous system. OCT allows for noninvasive measurements of RNFL thickness in micrometer resolution. With the help of OCT, researchers have managed to demonstrate that eyes of MS patients show distinct RNFL thinning after an event of acute optic neuritis in MS, and even subclinical damage in eyes with no previous optic neuritis. OCT is also a useful tool in terms of providing a differential diagnosis of MS toward, for example, neuromyelitis optica, a disease that usually shows stronger retinal thinning, or Susac syndrome, which is characterized by distinct patchy thinning of the inner retinal layers. RNFL thinning is associated with magnetic resonance imaging-derived measurements of the brain, such as whole-brain atrophy, gray and white matter atrophy, and optic radiation damage. These features suggest that OCT-derived retinal measurements are a complement for measuring central nervous system neurodegeneration in the context of clinical trials – for example, with neuroprotective substances.

    Full Text Available Background. Spasticity of the legs is common in multiple sclerosis (MS, but there has been limited research examining its association with ambulatory outcomes. Objective. This study examined spasticity of the legs and its association with multiple measures of ambulation in persons with MS. Methods. The sample included 84 patients with MS. Spasticity of the legs was measured using a 5-point rating scale ranging between 0 (normal and 4 (contracted. Patients completed the 6-minute walk (6 MW, timed 25 foot walk (T25FW, and timed up-and-go (TUG, and O2 cost of walking was measured during the 6 MW. The patients undertook two walking trials on a GAITRite (CIR systems, Inc. for measuring spatial and temporal parameters of gait. The patients completed the Multiple Sclerosis Walking Scale-12 (MSWS-12 and wore an accelerometer over a seven-day period. Results. 52% (n=44 of the sample presented with spasticity of the legs. Those with leg spasticity had significantly worse ambulation as measured by 6 MW (P=0.0001, d=-0.86, T25FW (P=0.003,d=0.72, TUG (P=0.001, d=0.84, MSWS-12 (P=0.0001,d=1.09, O2 cost of walking (P=0.001, d=0.75, average steps/day (P<0.05, d=-0.45, and walking velocity (P<0.05, d=-0.53 and cadence (P<0.05, d=-0.46.

In the validation cohort patients with antibody-mediated conditions were differentiated from multiple sclerosis with high accuracy. Both antibody-mediated conditions can be clearly separated from multiple sclerosis on conventional brain imaging, both in adults and children. The overlap between MOG antibody oligodendrocytopathy and AQP4 antibody astrocytopathy suggests that the primary immune target is not the main substrate for brain lesion characteristics. This is also supported by the clear distinction between multiple sclerosis and MOG antibody disease both considered primary demyelinating conditions. We identify discriminatory features, which may be useful in classifying atypical multiple sclerosis, seronegative neuromyelitis optica spectrum disorders and relapsing acute disseminated encephalomyelitis, and characterizing cohorts for antibody discovery. © The Author (2017).

    2014-01-01

    Full Text Available Multiple sclerosis is an autoimmune disease with classical traits of demyelination, axonal damage, and neurodegeneration. The migration of autoimmune T cells and macrophages from blood to central nervous system as well as the destruction of blood brain barrier are thought to be the major processes in the development of this disease. Chemokines, which are small peptide mediators, can attract pathogenic cells to the sites of inflammation. Each helper T cell subset expresses different chemokine receptors so as to exert their different functions in the pathogenesis of MS. Recently published results have shown that the levels of some chemokines and chemokine receptors are increased in blood and cerebrospinal fluid of MS patients. This review describes the advanced researches on the role of chemokines and chemokine receptors in the development of MS and discusses the potential therapy of this disease targeting the chemokine network.

    Full Text Available Morning glory syndrome (MGS is a rare congenital optic disc anomaly characterized by a funnel-shaped, excavated optic disc surrounded by chorioretinal pigmentary disturbance. The main ophthalomoscopic feature of the MGS is enlarged optic disc with a funnel shaped scleral defect; elevated peripapillary chorioretinal pigmentation; and pale fluffy tissue of glial hyperplasia overlying the optic disc. Although most of the reported cases were isolated ocular abnormality, but it may occurs in association with other ophthalmic abnormalities such as cyst of the optic nerve atrophy, congenital cataract, microophthalmos, and aniridia. Craniofacial deformities such as cleft lip and palate, hypertelorism, dysplatic ears; renal abnormalities; and cardiac defects have also been reported with MGS. Herein, we present a case of MGS associated with multiple sclerosis - a rather unusual concurrence.

    Full Text Available The therapeutic options for multiple sclerosis are rapidly expanding. What was once seen as a disease with little hope for treatment is now a target of rapid drug development. Current therapies have demonstrated efficacy in limiting the impact of the disease, but none is fully effective in all patients. However, promising new treatments are on the horizon. In this review we will discuss potential novel immunomodulating drugs that are in advanced stages of investigation; these drugs include monoclonal antibodies, chimeric molecules, and oral therapies. The use of hematopoietic stem cells will also be discussed and, in addition, we will look farther ahead at possible novel targets for the development of new immunomodulatory or neuroprotective pharmaceuticals.

  18. Multiple sclerosis genetics: leaving no stone unturned.

    Science.gov (United States)

    Oksenberg, J R; Barcellos, L F

    2005-08-01

    Compelling epidemiologic and molecular data indicate that genes play a primary role in determining who is at risk for developing multiple sclerosis (MS), how the disease progresses, and how someone responds to therapy. The genetic component of MS etiology is believed to result from the action of allelic variants in several genes. Their incomplete penetrance and moderate individual effect probably reflects epistatic interactions, post-transcriptional regulatory mechanisms, and significant environmental influences. Equally significant, it is also likely that locus heterogeneity exists, whereby specific genes influence susceptibility and pathogenesis in some individuals but not in others. With the aid of novel analytical algorithms, the combined study of genomic, transcriptional, proteomic, and phenotypic information in well-controlled study groups will define a useful conceptual model of pathogenesis and a framework for understanding the mechanisms of action of existing therapies for this disorder, as well as the rationale for novel curative strategies.

    2015-09-01

    Exercise training represents a behavioral approach for safely managing many of the functional, symptomatic, and quality of life consequences of multiple sclerosis (MS). This topical review paper summarizes evidence from literature reviews and meta-analyses, supplemented by recent individual studies, indicating that exercise training can yield small but important improvements in walking, balance, cognition, fatigue, depression, and quality of life in MS. The paper highlights limitations of research on exercise training and its consequences and future research directions and provides an overview for promotion of exercise training in MS based on recent prescriptive guidelines. Collectively, the evidence for the benefits of exercise training in MS suggests that the time is ripe for the promotion of exercise by healthcare providers, particularly neurologists as a central part of the clinical care and management of MS patients.

    Full Text Available Multiple sclerosis (MS is being increasingly diagnosed in India mainly due to increase in the number of practicing neurologists and easy and affordable availability of magnetic resonance imaging (MRI. The clinical features and course are largely similar to those seen in the West. The term optico-spinal MS (Asian MS was coined in the pre-MRI days. Many such patients turn out to be cases of neuromyelitis optica - a distinct disorder and not a variant of MS. Others have shown the classical features of MS on MRI scan. Several of the disease-modifying agents, not all, are now available in India. Their use, however, has been limited in view of the high cost.

  2. Modifiable environmental factors in multiple sclerosis

    Yara Dadalti Fragoso

    2014-11-01

    Full Text Available Potential environmental modifiable factors involved in multiple sclerosis (MS include low adherence to treatment, smoking, obesity, low levels of liposoluble vitamins A and D, high consumption of salt, and a sedentary lifestyle. Chronic tobacco use, obesity, sedentarism and insufficient levels of these vitamins all contribute to maintenance of a proinflammatory state. It is unlikely that there will be noticeable improvement in the inflammatory condition of MS if stopping smoking, reducing weight, exercising, increasing vitamin levels are done in an isolated and erratic manner. Modification of each and every one of these environmental risk factors is likely to be an important approach in the management of MS. The present review presents the arguments for an association between these hazardous modifiable factors and the chronic inflammatory state observed in MS.

    Juvenile rheumatoid arthritis (JRA) is the most common rheumatologic disease in children. Moreover, multiple sclerosis (MS) is the most frequent demyelinating disease and has been associated with various chronic inflammatory diseases. However, its association with JRA has not been frequently described. Autoimmunity in both JRA and MS has been documented in the scientific literature, although there has been no definitive finding that patients with JRA are prone to the development of MS. An increasing frequency of MS resulting from an increased use of antitumor necrosis factor agents in the treatment of rheumatoid arthritis and other chronic inflammatory diseases has been reported recently. In this study, we report on the development of MS in a patient with JRA who did not have a history of antitumor necrosis factor use.

    2001-09-01

    Multiple sclerosis (MS) is rare in children and occurs exceptionally before ten years. Sex ratio (girl/boy) is around 2.5 to 3, higher than in adults. Brain stem dysfunction and meningeal symptoms are more commonly first manifestations of the disease than in adults. Optic neuritis is also a frequent early manifestation. The etiology of the disease remains unclear and none of the advanced hypotheses (infectious, genetic, environmental) can by themselves explain its occurrence. There is a genetic susceptibility which is probably linked to many genes leading to a low related risk (less than two). A viral trigger mechanism in a person with a genetic predisposition is possible. New therapies result from a better understanding of the closed immune mechanisms of the disease.

    In the last few years, there has been an explosion of new drugs acting on the clinical course of multiple sclerosis (MS) but less attention has been paid to better knowledge of the symptoms of this disease and their pathogenesis and treatment, which is essential to improve patients' quality of life. Because many patients have numerous concurrent symptoms during their clinical course, their management is complex and consequently it is important to know which symptoms are a direct result of the degenerative lesions of MS. The present article describes all the therapeutic options available for spasticity and its associated pain, paroxystic symptoms, fatigue, genitourinary disorders and sexual dysfunction, tremor, ataxia, gait disorder and cognitive impairment, with special emphasis on novel treatments. The article also defines exacerbations, how to recognize them and the available treatments, mainly oral administration of high-dose methylprednisolone and plasmapheresis.

    Olsen, Tine Gadegaard; Frederiksen, Jette

    The association between multiple sclerosis (MS) and uveitis has been questioned. Nerve tissue and eye tissue develop from the same embryonic cells; thus, MS and uveitis could be etiologically associated. In published studies, the prevalence of MS in patients with uveitis differe from 0.7% to 30.4%, whereas the prevalence of uveitis in patients with MS differe from 0.65% to 36.7%. Based on the largest retrospective studies, the prevalence of uveitis among MS patients is ∼1%, and the prevalence of MS among patients with uveitis is ∼1%. This is considerably higher than in the general population; thus, more research on this topic is needed to further understand the relationship between MS and uveitis. Copyright © 2016 Elsevier Inc.

    Full Text Available Since 1993, six disease-modifying therapies for multiple sclerosis (MS have been proven to be of benefit in rigorous phase III clinical trials. Other agents are also available and are used to treat MS, but definitive data on their efficacy is lacking. Currently, disease-modifying therapy is used for relapsing forms of MS. This includes clinically isolated syndrome/first-attack high-risk patients, relapsing patients, secondary progressive patients who are still experiencing relapses, and progressive relapsing patients. The choice of agent depends upon drug factors (including affordability, availability, convenience, efficacy, and side effects, disease factors (including clinical and neuroimaging prognostic indicators, and patient factors (including comorbidities, lifestyle, and personal preference. This review will discuss the disease-modifying agents used currently in MS, as well as available alternative agents.

    To visualize and validate iron deposition in two cases of multiple sclerosis using rapid scanning X-Ray Fluorescence (RS-XRF) and Susceptibility Weighted Imaging (SWI). Two (2) coronal cadaver brain slices from patients clinically diagnosed with multiple sclerosis underwent magnetic resonance imaging (MRI), specifically SWI to image iron content. To confirm the presence of iron deposits and the absence of zinc-rich myelin in lesions, iron and zinc were mapped using RS-XRF. MS lesions were visualized using FLAIR and correlated with the absence of zinc by XRF. XRF and SWI showed that in the first MS case, there were large iron deposits proximal to the draining vein of the caudate nucleus as well as iron deposits associated with blood vessels throughout the globus pallidus. Less iron was seen in association with lesions than in the basal ganglia. The presence of larger amounts of iron correlated reasonably well between RS-XRF and SWI. In the second case, the basal ganglia appeared normal and acute perivascular iron deposition was absent. Perivascular iron deposition is seen in some but not all MS cases, giving credence to the use of SWI to assess iron involvement in MS pathology in vivo.

    Although chemical immunosuppression has been shown to benefit patients with chronic progressive multiple sclerosis (MS), it appears that chemotherapy has an appreciable oncogenic potential in patients with multiple sclerosis. Accordingly, we developed a modified total lymphoid irradiation (TLI) regimen designed to reduce toxicity and applied it to a randomized double blind trial of TLI or sham irradiation in MS. Standard TLI regimens were modified to reduce dose to 1,980 rad, lowering the superior mantle margin to midway between the thyroid cartilage and angle of the mandible (to avert xerostomia) and the lower margin of the mantle field to the inferior margin of L1 (to reduce gastrointestinal toxicity by dividing abdominal radiation between mantle and inverted Y), limiting spinal cord dose to 1,000 rad by custom-made spine blocks in the mantle and upper 2 cm of inverted Y fields, and also protecting the left kidney even if part of the spleen were shielded. Clinical efficacy was documented by the less frequent functional scale deterioration of 20 TLI treated patients with chronic progressive MS compared to to 20 sham-irradiated progressive MS patients after 12 months (16% versus 55%, p less than 0.03), 18 months (28% versus 63%, p less than 0.03), and 24 months (44% versus 74%, N.S.). Therapeutic benefit during 3 years follow-up was related to the reduction in lymphocyte count 3 months post-irradiation (p less than 0.02). Toxicity was generally mild and transient, with no instance of xerostomia, pericarditis, herpes zoster, or need to terminate treatment in TLI patients. However, menopause was induced in 2 patients and staphylococcal pneumonia in one.

    Using a piezoelectric transducer, the frequency and pattern of ocular microtremor (OMT) between 50 normal subjects and 50 patients with multiple sclerosis were compared. Controls were age matched. All records were analysed blindly. The frequency of OMT in the normal group was 86 (SD 6) Hz, which was significantly different from that of the multiple sclerosis group (71 (SD) 10 Hz, p<0.001). Those in the multiple sclerosis group with clinical evidence of brain stem or cerebellar disease (n=36) had an average OMT frequency of 67 (SD 9) Hz (p<0.001) compared with normal (n=86), whereas those with no evidence of brain stem or cerebellar involvement (n=14) had a frequency of 81.2 (SD 6) Hz (p<0.05, n=64). The differences between the two multiple sclerosis groups were also significant (p<0. 001, n=50). At least one abnormality (frequency and pattern) of OMT activity was seen in 78% of patients with multiple sclerosis. In the presence of brain stem or cerebellar disease 89% had abnormal records whereas in the absence of such disease 50% had abnormal records. This is the first report of the application of this technique to patients with multiple sclerosis. The results suggest that OMT activity may be of value in the assessment of multiple sclerosis.

    It is unclear how people with multiple sclerosis, who often have compromised strength and balance, compare to healthy controls during sit-to-stand movements. The purpose of this study was to compare sit-to-stand biomechanics among three groups: people with multiple sclerosis who exhibit leg weakness, people with multiple sclerosis who have comparable strength to controls, and healthy controls. Twenty-one individuals with multiple sclerosis (n=10 exhibiting leg weakness: n=11 exhibiting comparable strength to controls), and 12 controls performed five sit-to-stand trials while kinematic data and ground reaction forces were captured. ANOVAs followed by Tukey's post-hoc tests (α=0.05) were used to determine group and limb differences for leg strength, movement time, and sagittal-plane joint kinematics and kinetics. Persons with multiple sclerosis exhibiting leg weakness displayed decreased leg strength, greater trunk flexion, faster trunk flexion velocity and decreased knee extensor power compared to the other two groups (psit-to-stand (p≤0.05). Participants with multiple sclerosis exhibiting leg weakness took longer to stand and appeared to use a trunk-flexion movement strategy when performing the sit-to-stand. The majority of group differences appear to be a result of leg extension weakness. Treatment that includes leg strengthening may be necessary to improve sit-to-stand performance for people with multiple sclerosis. Copyright © 2015. Published by Elsevier Ltd.

    Helmar Bornemann-Cimenti

    Full Text Available Abstract Background and objectives: Current guidelines for neuraxial analgesia in patients with multiple sclerosis are ambiguous and offer the clinician only a limited basis for decision making. This systematic review examines the number of cases in which multiple sclerosis has been exacerbated after central neuraxial analgesia in order to rationally evaluate the safety of these procedures. Methods: A systematic literature search with the keywords "anesthesia or analgesia" and "epidural, peridural, caudal, spinal, subarachnoid or intrathecal" in combination with "multiple sclerosis" was performed in the databases PubMed and Embase, looking for clinical data on the effect of central neuraxial analgesia on the course of multiple sclerosis. Results and conclusions: Over a period of 65 years, our search resulted in 37 reports with a total of 231 patients. In 10 patients multiple sclerosis was worsened and nine multiple sclerosis or neuromyelitis optica was first diagnosed in a timely context with central neuraxial analgesia. None of the cases showed a clear relation between cause and effect. Current clinical evidence does not support the theory that central neuraxial analgesia negatively affects the course of multiple sclerosis.

    Full Text Available As Lyme neuroborreliosis (LNB may clinically mimick multiple sclerosis (MS the presence of antibodies to Borrelia burgdorferi in serum of patients with a MS-like disease in non-edemic areas for Lyme disease may be troublesome. We report the case of a 45-year-old white female with the diagnosis of relapsing/ remitting form of MS due to a 15-year history of optic neuritis and recurrent episodes of motor and sensation disturbance in the upper right limb and in both lower extremites associated with bladder dysfunction. A magnetic resonance imaging of the brain revealed multiple high intensity periventricular white matter lesions. The patient had been exposed to ticks but did not recall the presence of erythema migrans. ELISA for Lyme disease was positive in two different laboratories and the positive serology was confirmed by Western blotting. No convincing reponse followed treatment with ceftriaxone. Although it is clear that the patient had been infect by Borrelia burgdorferi the relationship of this spirochetal infection with the neurological disease could not be ascertained.

  16. The symptomatic management of multiple sclerosis

    Directory of Open Access Journals (Sweden)

    2009-01-01

    Full Text Available The management of multiple sclerosis (MS revolves around disease management, symptom management, and person management. Of these, symptom management takes up the bulk of the time of the practicing physician. Some symptoms are easily managed whereas others are more difficult. Decisions have often to be made on whether to treat or to wait and watch. This article discusses the varied symptoms of MS and the approaches to management, which involves rehabilitation, pharmacological treatments, and surgical procedures. The skilled physician managing MS should be familiar with the multiple approaches to improving the quality of life of those with MS. After the diagnosis has been established and the decisions regarding treatment approaches have been made, the talk in a typical office appointment for MS usually turns to symptom management. Thus, the majority of management decisions made by the clinician revolve around that important topic. It is symptom management that will determine quality of life for those with MS, It is the basis for improving function, and, up until twenty years ago, it was the only basis for treating MS. Now, however, we can approach treatment by disease management, symptom management, and person management. The MS specialist must be well versed in all three areas.

    Under certain conditions or at certain stages of the disease course, multiple sclerosis (MS) and mitochondrial disorder (MID) may be differential diagnoses and thus may be confused with each other. In a 30 years old female MS was diagnosed at age 16 year upon recurrent sensory disturbances of the right lower leg, an "inflammatory" cerebrospinal fluid, and a cerebral MRI with multiple non-enhancing white matter lesions. Steroids were repeatedly given but because of rapid deterioration treatment was switched to interferon and mitoxantrone, without improvement. Fourteen years after onset the patient additionally presented with a history of rhabdomyolysis, hypothyroidism, ophthalmoparesis, anarthria, tetraspasticity, tetraparesis, and joint contractures. After MID had been diagnosed in her mother she was re-evaluated and elevated resting lactate, axonal polyneuropathy, and empty sella were additionally found. Muscle biopsy revealed myophagy, fat deposition, and type-II predominance, and biochemical investigations showed a deficiency of complex I and IV of the respiratory chain. MID was diagnosed also in the index patient. It is concluded that even if CSF investigations or imaging studies suggest MS, differentials such as MIDs need to be excluded before prescribing medication possibly toxic to a MID. An "inflammatory CSF" may also occur in MIDs.

    Full Text Available Multiple sclerosis, often called MS, is a disease that affects the central nervous system (the brain and spinal cord. Myelin provides insulation for nerve cells improves the conduction of impulses along the nerves and is important for maintaining the health of the nerves. In multiple sclerosis, inflammation causes the myelin to disappear. Genetic factors, environmental issues and viral infection may also play a role in developing the disease. Ms is characterized by life threatening symptoms such as; loss of balance, hearing problem and depression. The application of Fuzzy Cluster Means (FCM or Fuzzy CMean analysis to the diagnosis of different forms of multiple sclerosis is the focal point of this paper. Application of cluster analysis involves a sequence of methodological and analytical decision steps that enhances the quality and meaning of the clusters produced.

  7. Metabolic pathways as possible therapeutic targets for progressive multiple sclerosis

    Rebecca M Heidker

    2017-01-01

    Full Text Available Unlike relapsing remitting multiple sclerosis, there are very few therapeutic options for patients with progressive forms of multiple sclerosis. While immune mechanisms are key participants in the pathogenesis of relapsing remitting multiple sclerosis, the mechanisms underlying the development of progressive multiple sclerosis are less well understood. Putative mechanisms behind progressive multiple sclerosis have been put forth: insufficient energy production via mitochondrial dysfunction, activated microglia, iron accumulation, oxidative stress, activated astrocytes, Wallerian degeneration, apoptosis, etc. Furthermore, repair processes such as remyelination are incomplete. Experimental therapies that strive to improve metabolism within neurons and glia, e.g., oligodendrocytes, could act to counter inadequate energy supplies and/or support remyelination. Most experimental approaches have been examined as standalone interventions; however, it is apparent that the biochemical steps being targeted are part of larger pathways, which are further intertwined with other metabolic pathways. Thus, the potential benefits of a tested intervention, or of an established therapy, e.g., ocrelizumab, could be undermined by constraints on upstream and/or downstream steps. If correct, then this argues for a more comprehensive, multifaceted approach to therapy. Here we review experimental approaches to support neuronal and glial metabolism, and/or promote remyelination, which may have potential to lessen or delay progressive multiple sclerosis.

  8. The Ocular Manifestations of Drugs Used to Treat Multiple Sclerosis.

    2017-03-01

    Recent times have seen an increase in the number of options to treat multiple sclerosis. Ocular manifestations of multiple sclerosis are well known to treating physicians; however, the medications used to treat multiple sclerosis can also have ocular side effects. This review article focuses on the ocular manifestations of corticosteroids and disease-modifying agents such as interferon, fingolomod, natalizumab, alemtuzumab and mitoxantron used to treat the disease. The ocular manifestations of multiple sclerosis treatments can be varied depending on the drug used, and include retinopathy, chronic central serous chorioretinopathy, macular oedema, Graves' ophthalmopathy and cortical blindness. These effects may be specific to the drug or secondary to their immunosuppressive effect. The association of macular oedema with fingolomod is clear and merits ocular screening for toxicity. The immunosuppressive nature of the treatments makes patients prone to acquired infections. Hence, if a patient with multiple sclerosis presents with vision loss, infectious and drug-induced aetiology should be considered alongside relapses of multiple sclerosis itself as a cause.

    The aim of our study is to evaluate the extent and distribution of grey matter demyelinating lesions in multiple sclerosis (MS), addressing also neuronal loss and synaptic loss. Whole coronal sections of 6 MS brains and 6 control brains were selected. Immunohistochemistry was performed for myelin basic protein, neurofilaments, synaptophysin, ubiquitin, and activated caspase-3. Neuronal density and optical density of synaptophysin staining were estimated in cortical lesions and compared with those observed in corresponding areas of normal (i.e. nondemyelinated) cortex in the same section. Demyelinating lesions were observed in the cerebral cortex, in the thalamus, basal ganglia, and in the hippocampus. The percentage of demyelinated cortex was remarkable in 2 cases of secondary progressive MS (48% and 25.5%, respectively). Neuronal density was significantly reduced in cortical lesions (18-23% reduction), if compared with adjacent normal cortex, in the 2 cases showing the higher extent of cortical demyelination; in the same cases, very rare apoptotic neurons expressing caspase-3 were observed in cortical lesions and not in adjacent normal cortex. No significant decrease in optical density of synaptophysin staining was observed in cortical lesions. Grey matter demyelination and neuronal loss could contribute to disability and cognitive dysfunctions in MS.

    Dimitry Ofengeim

    2015-03-01

    Full Text Available Multiple sclerosis (MS, a common neurodegenerative disease of the CNS, is characterized by the loss of oligodendrocytes and demyelination. Tumor necrosis factor α (TNF-α, a proinflammatory cytokine implicated in MS, can activate necroptosis, a necrotic cell death pathway regulated by RIPK1 and RIPK3 under caspase-8-deficient conditions. Here, we demonstrate defective caspase-8 activation, as well as activation of RIPK1, RIPK3, and MLKL, the hallmark mediators of necroptosis, in the cortical lesions of human MS pathological samples. Furthermore, we show that MS pathological samples are characterized by an increased insoluble proteome in common with other neurodegenerative diseases such as Alzheimer’s disease (AD, Parkinson’s disease (PD, and Huntington’s disease (HD. Finally, we show that necroptosis mediates oligodendrocyte degeneration induced by TNF-α and that inhibition of RIPK1 protects against oligodendrocyte cell death in two animal models of MS and in culture. Our findings demonstrate that necroptosis is involved in MS and suggest that targeting RIPK1 may represent a therapeutic strategy for MS.

  11. Chemokine Receptors as Biomarkers in Multiple Sclerosis

    Directory of Open Access Journals (Sweden)

    2006-01-01

    Full Text Available Leukocyte infiltrates characterize tissue inflammation and are thought to be integral in the pathogenesis of multiple sclerosis (MS. This attribute underlines the importance of understanding mechanisms of leukocyte migration. Chemokines are secreted proteins which govern leukocyte trafficking into targeted organs. Chemokine receptors (CKR are differentially expressed on leukocytes and their modulation is a potential target for MS disease modifying therapies. Chemokines and their receptors are also potential biomarkers of both disease activity and response to treatment. We describe the fluctuations in CKR expression on peripheral leukocytes in a group of MS patients followed longitudinally for up to 36 months. We observed little fluctuation in CKR expression within each patient over time, despite considerable variability in CKR expression between patients. These observations suggest that individual patients have a CKR set point, and this set point varies from one patient to another. Evaluation of chemokines or chemokine receptors as biomarkers in MS will need to account for this individual variability in CKR expression.

    BACKGROUND: Type 1 diabetes mellitus (T1D) and multiple sclerosis (MS) contribute considerably to the burden of autoimmune diseases in young adults. Although HLA patterns of T1D and MS are considered mutually exclusive, individual and familial co-occurrence of the 2 diseases has been reported...... on national age, sex, and period-specific MS and T1D incidence rates. RESULTS: Patients with T1D were at more than 3-fold increased risk for development of MS (relative risk, 3.26; 95% confidence interval, 1.80-5.88; n = 11). First-degree relatives of patients with MS were at 63% increased risk (relative risk......, 1.63; 95% confidence interval, 1.26-2.12; n = 56) for development of T1D. However, adjusting for familial relationship to patients with T1D reduced the excess risk to 44% (relative risk, 1.44; 95% confidence interval, 1.11-1.88; n = 56). CONCLUSION: The present nationwide cohort study demonstrates...

    2016-01-01

    Background: Identifying the transition from relapsing-remitting to secondary progressive multiple sclerosis (SPMS) can be challenging for clinicians. Little previous research has explored how professionals experience working with patients during this specific stage of the disease. We explored the experiences of a group of multidisciplinary professionals who support patients in the transition to SPMS to describe this stage from a professional perspective. Methods: This qualitative semistructured interview study included 11 professionals (medical, nursing, and allied health professionals; specialists and generalists) working with patients with MS in South Wales, United Kingdom. Thematic analysis of the interview data was performed. Results: Two overarching themes were identified: the transition and providing support. The transition theme comprised issues related to recognizing and communicating about SPMS. Uncertainty influenced recognizing the transition and knowing how to discuss it with patients. The providing support theme included descriptions of challenging aspects of patient care, providing support for caregivers, using the multidisciplinary team, and working within service constraints. Providing adequate psychological support and engaging patients with self-management approaches were seen as particularly challenging. Conclusions: Caring for patients in the transition to SPMS generates specific challenges for professionals. Further research on health-care interactions and patients'/professionals' experiences regarding the transition phase may help identify strategies for professional development and learning and how to optimize the patient experience at this difficult stage of disease.

    Multiple sclerosis (MS) is an autoimmune and inflammatory disease of the central nervous system (CNS) that causes neurological disability in young adults and that to date has no cure. Until now, expensive and only partially efficacious therapies have become available. For this reason, researchers, clinicians and pharmaceutical companies are currently investigating new drugs for the treatment of MS. Here, we review the most recent data on drug candidates for MS. In the preclinical phase, such drug candidates have shown a beneficial effect on the onset of experimental autoimmune encephalomyelitis (microtubule-stabilizing drugs, MS14, Lithium, GEMSP...), a decrease in CNS cell infiltrates (recombinant T cell receptor ligand, lovastatin-rolipram, ribavirin, GEMSP...), prevention of demyelination (lovastatin-rolipram, calpain inhibitor, lithium...); and a reduction of axonal loss (phenytoin, lovastatin-rolipram, calpain inhibitor). In clinical trials, drug candidates against MS have shown safety (rituximab, ustekinumab, intravenous immunoglobulin, laquinimod, BHT-3009, fumarate, chaperonin 10, GEMSP...), an improvement of gadolinium-enhanced lesions (protiramer, fingolimod, laquinimod, BHT-3009, fumarate, daclizumab...), and an improvement of the relapse rate (fingolimod, fumarate...). Future research into MS should focus on a combination of therapies and on the development of drugs directed against the remitting and progressive phases of the disease. In this sense, MS is a very complex multifactorial disease that requires treatment able to cover all the aspects of MS and not only the anti-inflammatory aspect.

  15. B Cells and Autoantibodies in Multiple Sclerosis

    2015-07-01

    Full Text Available While over the past decades T cells have been considered key players in the pathogenesis of multiple sclerosis (MS, it has only recently become evident that B cells have a major contributing role. Our understanding of the role of B cells has evolved substantially following the clinical success of B cell-targeting therapies and increasing experimental evidence for significant B cell involvement. Rather than mere antibody-producing cells, it is becoming clear that they are team players with the capacity to prime and regulate T cells, and function both as pro- and anti-inflammatory mediators. However, despite tremendous efforts, the target antigen(s of B cells in MS have yet to be identified. The first part of this review summarizes the clinical evidence and results from animal studies pointing to the relevance of B cells in the pathogenesis of MS. The second part gives an overview of the currently known potential autoantigen targets. The third part recapitulates and critically appraises the currently available B cell-directed therapies.

    Full Text Available Multiple sclerosis (MS is a chronic immune-mediated disorder of the central nervous system, affecting women of childbearing age. Little is known about the possible association between mode of delivery and the risk of MS in offspring. Delivery represents a unique event in a woman’s lifetime, with complex mechanisms controlling human parturition. Concurrent with the trend of increasing numbers of caesarean deliveries (CD, there has been an increasing frequency of autoimmune diseases such as MS. Several theories have emerged suggesting that environmental influences are contributing to this phenomenon. The data available in literature seem reassuring for women with MS, suggesting that the disease is not associated with adverse pregnancy or birth outcomes. On the other hand, there is little information in the literature regarding the role of mode of delivery in predicting the postpartum disease activity, pregnancy, and birth outcomes in women with MS. The aim of our review is to provide a brief summary of the available data on the role of mode of delivery in MS, and the eventual correlation with disease outcome.

    BACKGROUND: The validity of self-rated anxiety inventories in people with multiple sclerosis (pwMS) is unclear. However, the appropriateness of self-reported depression scales has been widely examined. Given somatic symptom overlap between depression and MS, research emphasises caution when using such scales. OBJECTIVE: This study evaluates symptom overlap between anxiety and MS in a group of 33 individuals with MS, using the Beck Anxiety Inventory (BAI). METHODS: Participants underwent a neurological examination and completed the BAI. RESULTS: A novel procedure using hierarchical cluster analysis revealed three distinct symptom clusters. Cluster one (\\'wobbliness\\' and \\'unsteady\\') grouped separately from all other BAI items. These symptoms are well-recognised MS-related symptoms and we question whether their endorsement in pwMS can be considered to reflect anxiety. A modified 19-item BAI (mBAI) was created which excludes cluster one items. This removal reduced the number of MS participants considered \\'anxious\\' by 21.21% (low threshold) and altered the level of anxiety severity for a further 27.27%. CONCLUSION: Based on these data, it is suggested that, as with depression measures, researchers and clinicians should exercise caution when using brief screening measures for anxiety in pwMS.

    Several studies have reported high rates of depression in multiple sclerosis (MS) with a lifetime prevalence of approximately 50% and an annual prevalence of 20% not uncommon. Concern about the potential of new drug treatments to exacerbate or precipitate depression in MS has led to increased interest in the relation between MS and depression. This review on MS and depression identifies the following key issues: How common is depression in people with MS? Is depression in MS associated with lesions in specific regions of the central nervous system? Is there an increased risk of suicide in MS? Is there a higher than expected incidence of anxiety disorders in MS? Are fatigue and depressed mood related in MS? Is there a relation between depression and cognitive impairment in MS? Which psychosocial variables affect the development of depression in MS? Does treatment with interferon increase the risk of depression? How effective are treatments for MS patients with depression? Each of these issues is briefly reviewed with critical commentary, and some priorities for future research are suggested.

    Multiple sclerosis is a central nervous system disease. It is mainly characterized by passing neurological disorders at first which alter into permanent symptoms. The most frequent are tiredness, sensation disturbance and limbs, face, body becoming numb. Pregnancy doubtfully influence MS, but the most important question is about treatment during pregnancy. Should we carry pregnancy during immunomodular treatment? But crucial aspect is if a newborn baby will be healthy. To make attempt into discussion about the subject of SM and pregnancy we should perform a test how many sick people get married and or if maternity and paternity influence a disease course. Our research may bring answers, why statistically less SM men become single and do not own children and if unmarried status is influenced by sexual disturbance. Our conclusion will be compared with already written facts. Patients were between 18-35 year old are the subject of research. The group consist of 24 patients, 9 men and 15 women. Final conclusion could bring the answer if definite willingness to have a baby should be recommended.

    Prevalence of multiple sclerosis (MS) was evaluated in the pilot study of 731 patients living in Tyumen city and a southern part of Tyumen region as well as in Khanty-Mansi (KMAO) and Yamal-Nenets (YNAO) autonomic okrugs. An index of MS prevalence was 22,4 per 100,000 in Tyumen region as a whole. This index was higher--29.1 per 100 000 - in the southern part. In KMAO and YNAO, the MS prevalence was 14,3 and 27,8 respectively. Women prevailed among patients in all the regions, their number being twice higher (461 and 270). However, if in the southern part and in KMAO this ratio was approximately equal, in YNAO percentage of men was significantly higher. It should be noted that these data need further study. We revealed that using of current diagnostic criteria may often lead to misunderstanding of diagnosis of "definite" MS. Essential difference in MS prevalence in different regions may be explained by ethnical stratification. In particular, there are many newly migrated people in the okrugs and MS occurs more often in that group. At the same time, there is no any information on the prevalence of "definite" MS among the native-born population of KMAO and YNAO.

    Before the advent of diagnostic criteria for multiple sclerosis (MS), it was reported that the prevalence of MS in Mexico was "one of the lowest in the world" (1.6/100,000).(1) The notion that MS was a rare neurologic disease among those living in the tropics of the Americas and Southern latitudes was widely accepted. The geopolitical boundaries of the region identified as Latin America (LA) extend from the southern border of United States with Mexico (32° North latitude) to the Argentinian and Chilean Patagonia in South America (56° South latitude). The largest Spanish-speaking island countries in the Caribbean-Cuba, Dominican Republic, and Puerto Rico-are also traditionally considered part of LA. The continental mass includes 17 countries with a population of more than 550 million. Due to centuries of racial intermixing, it is a heterogeneous and genetically complex population. The blended cultures of native Amerindians with white Caucasian Europeans and black Africans has resulted in the predominant ethnic Latin American Mestizo. The influence of African genetics is notable in many areas of the subcontinent and the Caribbean. A common observation across LA is the absence of identification of MS in non-mixed Amerindians(2); the reason for this phenomenon is unclear.

    Multiple sclerosis (MS) is the most common autoimmune inflammatory demyelinating disease of the central nervous system, affecting over 2.3 million people worldwide. According to the National Institute of Neurological Disorders and Stroke, the age of disease onset is typically between 20 and 40 years, with a higher incidence in women. Individuals with MS experience a wide range of symptoms, including declining physical, emotional, and psychological symptoms (e.g., fatigue, imbalance, spasticity, chronic pain, cognitive impairment, bladder and bowel dysfunction, visual and speech impairments, depression, sensory disturbance, and mobility impairment). To date, both the cause of and cure for MS remain unknown. In recent years, more individuals with MS have been pursuing alternative methods of treatment to manage symptoms of the disease, including mind-body therapies such as yoga, meditation, breathing, and relaxation techniques. It has been suggested that the practice of yoga may be a safe and effective way of managing symptoms of MS. Therefore, the purpose of this paper is to summarize the most relevant literature on exercise and mind-body modalities to treat MS symptoms and, more specifically, the benefits and potential role of yoga as an alternative treatment of symptom management for individuals with MS. The article also discusses future directions for research.

    Multiple sclerosis (MS) is a complex disorder of the central nervous system whose cause is currently unknown. Evidence is increasing that DNA methylation alterations could be involved in inflammatory and neurodegenerative diseases and could contribute to MS pathogenesis. Repetitive elements Alu, LINE-1 and SAT-α, are widely known as estimators of global DNA methylation. We investigated Alu, LINE-1 and SAT-α methylation levels to evaluate their difference in a case-control setup and their role as a marker of disability. We obtained blood samples from 51 MS patients and 137 healthy volunteers matched by gender, age and smoking. Methylation was assessed using bisulfite-PCR-pyrosequencing. For all participants, medical history, physical and neurological examinations and screening laboratory tests were collected. All repetitive elements were hypermethylated in MS patients compared to healthy controls. A lower Expanded Disability Status Scale (EDSS) score was associated with a lower levels of LINE-1 methylation for 'EDSS = 1.0' and '1.5 ≤ EDSS ≤ 2.5' compared to an EDSS higher than 3, while Alu was associated with a higher level of methylation in these groups: 'EDSS = 1.0' and '1.5 ≤ EDSS ≤ 2.5'. MS patients exhibit an hypermethylation in repetitive elements compared to healthy controls. Alu and LINE-1 were associated with degree of EDSS score. Forthcoming studies focusing on epigenetics and the multifactorial pathogenetic mechanism of MS could elucidate these links further.

    Autologous haematopoietic cell transplantation (AHCT) is an evolving treatment avenue in multiple sclerosis (MS), which may be highly effective in controlling disease activity and improving disability. However, AHCT is associated with intrinsic toxicities and risks compared with conventional therapies. With growing experience in patient selection and treatment delivery, AHCT is increasingly considered an option in patients with aggressive disease that's responding poorly to disease modifying therapy. Areas covered: This article provides an introduction to AHCT and looks at its development as a treatment for MS over the last 20 years. It also highlights potential mechanisms of action, patient selection, and future trends for this treatment approach. Expert opinion: Currently published data suggest that AHCT's use is associated with significant reduction in MS disease activity and marked improvement in disability when used in patients with highly active relapsing remitting disease. Its long term safety and efficacy have not been fully evaluated but as increasing clinical trial data are published, its use is likely to grow. Further randomised controlled studies are needed to compare AHCT with standard disease modifying therapies and to optimise transplant regimens. Mechanistic studies may provide potential markers for response and a better understanding of disease pathogenesis.

    Full Text Available Background: Connective tissue diseases (CTD can involve nervous system. Diagnosis and differentiation from multiple sclerosis (MS can be difficult especially when the disease presented by symptoms and signs related to demyelinating process. The aim of this article is to review the variant forms of central nervous system involvement in CTD especially useful points for differentiation from demyelinating disorders. Materials and Method: We used the relevant articles in PUBMED, Scopus and other databases especially published in recent ten years. Results: Systemic lupus erythematosus (SLE, antiphospholipid syndrome (APS, Behcet’s disease (BD, Sjogren's syndrome (SS, and some vasculitides can involve nervous system. Patients may be present by demyelination areas in the white matter of the brain and spinal cord, which are difficult to differentiate from MS and other demyelinating processes, such as transverse myelitis and optic neuritis. On the other hand, autoantibodies such as antinuclear antibodies (ANA and antiphospholipid antibodies (aPL can also occur in MS. Treatment and prognosis of these diseases are quite different. In demyelinating diseases the diagnosis is established on the basis of clinical presentation, magnetic resonance imaging (MRI, cerebrospinal fluid (CSF examination, visual evoked potentials (VEP and autoantibody investigation.Conclusion: In many patients, distinction between different etiologies of demyelination can be made by considering clinical and paraclinical data, but in some cases, accurate diagnosis can only be made after long-term follow-up

    Full Text Available The purpose of the study was to identify changes in cognitive abilities that affect patients with relapsing remitting form of multiple sclerosis (MS and to find out which instrument manifests them best. The performance of MS patients was compared to a matched group of healthy people using three neuropsychological tests: Wisconsin card sorting test (WCST, Stroop color and word test and Trail making test (TMT part B. Results on all three tests indicate general cognitive impairments in the group of patients. Compared to the group of healthy people patients with MS exhibited impaired ability of abstract reasoning (WCST, impaired cognitive flexibility and less resistance to irrelevant stimuli (Stroop color and word test, slowed information processing and impaired ability of shifting attention from one symbol to another (TMT. The largest differences between groups occured in Stroop color and word test as well as in TMT. The estimation of cognitive abilities of MS patients is of high importance and sistematicaly observing of changes in those abilities should be considered.

    We studied 24 patients with multiple sclerosis (MS) by proton magnetic resonance spectroscopic imaging (1H-MRSI) to assess the neurochemical pathology of the white-matter lesions (WML) and normal-appearing white matter (NAWM). Our 1H-MRSI technique allowed simultaneous measurement of N-acetylaspartate (NAA), choline-containing compounds (Cho), and creatine plus phosphocreatine (Cr) signal intensities from four 15-mm slices divided into 0.84 ml single-volume elements. In WML we found significantly lower NAA/Cr and NAA/Cho ratios and a significantly higher Cho/Cr ratio than in NAWM or control white matter. In NAWM, NAA/Cr and Cho/Cr were significantly lower than in control white matter. 1H-MRSI was compatible with damage to myelin in WML, and with axonal damage and/or dysfunction in WML and NAWM. These findings extend data on involvement of NAWM in MS beyond the abnormalities visible on MRI. (orig.)

    Multiple sclerosis (MS)(1) is a chronic neurodegenerative disease involving destruction of the myelin sheath around axons of the brain, spinal cord and optic nerve. There has been a tremendous transformation in its perspective across globe. In recent years, its prevalence has changed dramatically worldwide and India is no exception. Initially, MS was believed to be more common in the Caucasians of Northern Europe and United States; however, it has been found to be present in Indian subcontinent as well. There has been a considerable shift in MS prevalence in India and this has really changed the notion of considering India as a low risk zone for MS. In this review, a concise overview and latest update on changing scenario of MS in India is presented along with some major challenges regarding it persisting across globe even today. In India, remarkable upsurge is needed in carrying out large scale population-based epidemiological studies to get an idea about the true incidence and prevalence rates of MS viz a viz disease burden. Through this review, we have probably tried to identify the actual picture of MS prevalence in India and this could serve as harbinger for upcoming research and at the same time it would definitely aid in working out future strategies for MS management in the country.

    Full Text Available Pegylation is a procedure used for drug development since the 1970s and consists of the conjugation of a polyethylene glycol molecule (PEG to a drug. PEG has shown to be safe and effective in improving the pharmacokinetic and pharmacodynamic profile of drugs. Recently, a 20 kDa linear chain of PEG was conjugated to interferon beta-1a with the aim to offer a new treatment option to relapsing-remitting multiple sclerosis (RRMS patients. Due to a prolonged bioavailability, this new drug can be administered less frequently (every two weeks than the other interferons beta available, thus allowing to hypothesize a better adherence to the treatment, which, in turn, should result in better clinical and economic outcomes. A phase III clinical trial has proven its effectiveness compared to placebo in RRMS patients, as well as a safety profile comparable to that found in other interferon beta preparations. The immunogenicity of this new molecule is < 1%, thus minimizing the suppression or reduction of interferon beta biological activity that could come from the development of Neutralizing Antibodies (NAbs.

    Lesion segmentation plays an important role in the diagnosis and follow-up of multiple sclerosis (MS). This task is very time-consuming and subject to intra- and inter-rater variability. In this paper, we present a new tool for automated MS lesion segmentation using T1w and fluid-attenuated inversion recovery (FLAIR) images. Our approach is based on two main steps, initial brain tissue segmentation according to the gray matter (GM), white matter (WM), and cerebrospinal fluid (CSF) performed in T1w images, followed by a second step where the lesions are segmented as outliers to the normal apparent GM brain tissue on the FLAIR image. The tool has been validated using data from more than 100 MS patients acquired with different scanners and at different magnetic field strengths. Quantitative evaluation provided a better performance in terms of precision while maintaining similar results on sensitivity and Dice similarity measures compared with those of other approaches. Our tool is implemented as a publicly available SPM8/12 extension that can be used by both the medical and research communities. (orig.)

    Full Text Available ABSTRACT This cross-sectional study involves 100 multiple sclerosis (MS and 100 non-MS patients, under the age of 60 years old, with nasal obstruction, traumatic brain injury, previous rhinoplasty or neurosurgery, and so forth. Objective To assess olfactory function using the Connecticut test and verify correlations between olfactory alteration, disease duration and the Expanded Disability Status Scale (EDSS. Methods One hundred MS patients and 100 healthy control patients responded to a questionnaire. Those with olfactory alteration underwent a facial CT to exclude other causes. Results Thirty-two percent of patients showed alterations, compared with 3% in the healthy control group. Patients having EDSS above 4, showed a 5.2-times increased risk of dysfunction. Patients over 38 years of age have a 2.2-times increased risk over younger patients. Conclusions Because MS patients are likely to experience olfactory alterations, this study is a useful tool in follow-up care, although more studies are necessary to evaluate the correlations in MS evolution.

    Full Text Available Objectives: The aim of the study was the epidemiological analysis and evaluation of selected clinical and sociodemographic factors in Polish patients with primary progressive multiple sclerosis. Methods: The study included patients from 7 provinces in central and eastern Poland registered in the Registry of Patients with Multiple Sclerosis on 31 December 2016. The incidence of various forms of the disease was compared, and clinical, demographic and social disparities between relapsing-remitting and primary progressive multiple sclerosis were analysed. Results: Of 3,199 registered patients, 2,188 persons (66.2% had the relapsing-remitting form of multiple sclerosis, 774 (24.2% had the secondary progressive type and 307 (9.6% suffered from primary progressive disease. The first symptoms of primary progressive multiple sclerosis appeared almost 10 years later than in patients with the relapsing-remitting type (39.2 ± 11.4 vs. 29.8 ± 9.8. The period from the first symptoms to diagnosis was more than twice as long in patients with primary progressive multiple sclerosis (5.8 ± 3.4 as in those with relapsing-remitting disease (2.4 ± 1.6. The average degree of disability in the Expanded Disability Status Scale was similar and amounted to 3.2 ± 2.1 for relapsing-remitting and 3.6 ± 2.4 for primary progressive multiple sclerosis. The relapsing-remitting form was observed more often in women (2.4:1, and the primary progressive form appeared with equal frequency in both sexes (1:1. Disease-modifying treatment was received by 34% of patients with relapsing-remitting and in only 1.9% of patients with primary progressive multiple sclerosis. Conclusions: The primary progressive form affects approximately 10% of Polish patients with multiple sclerosis. The first symptoms appear at about 40 years of age with equal frequency in both sexes, and its diagnosis takes more than twice as much time as in the case of relapsing-remitting multiple

    The MSDS (multiple sclerosis documentation system) has been developed at the Department of Neurology, Technical University of Dresden, Germany, during the last 4 years. The first version of this database application has been in use since October 2000. The MSDS manages information on MS patients, their treating physicians, patient history (symptoms, other diseases, biographical history, family history, habits, medication), clinical signs, results of laboratory examinations (blood chemistry, autoantibodies, borrelia serology, evoked potentials, cranial and spinal cord magnetic resonance imaging), clinical scores relevant for MS, and biosamples. In principle, MSDS allows online data input and semiautomatically generates reports to all general practitioners and neurologists treating the respective patient. Patient information sheets and internal treatment guidelines are part of the system. During a 3-month evaluation, the first version of MSDS was tested at eight university multiple sclerosis ambulatory care units and one general neurology hospital. The overall judgement was favorable. Suggestions for changes and improvements, as well as practical experiences, were considered when developing MSDS 2.0, which will be available by the end of 2001.

    Optic neuritis is an acute inflammatory condition that is highly associated with multiple sclerosis. Currently, the best predictor of future development of multiple sclerosis is the number of T2 lesions visualized by magnetic resonance imaging. Previous research has found abnormalities in the permeability of the blood–brain barrier in normal-appearing white matter of patients with multiple sclerosis and here, for the first time, we present a study on the capability of blood–brain barrier permeability in predicting conversion from optic neuritis to multiple sclerosis and a direct comparison with cerebrospinal fluid markers of inflammation, cellular trafficking and blood–brain barrier breakdown. To this end, we applied dynamic contrast-enhanced magnetic resonance imaging at 3 T to measure blood–brain barrier permeability in 39 patients with monosymptomatic optic neuritis, all referred for imaging as part of the diagnostic work-up at time of diagnosis. Eighteen healthy controls were included for comparison. Patients had magnetic resonance imaging and lumbar puncture performed within 4 weeks of onset of optic neuritis. Information on multiple sclerosis conversion was acquired from hospital records 2 years after optic neuritis onset. Logistic regression analysis showed that baseline permeability in normal-appearing white matter significantly improved prediction of multiple sclerosis conversion (according to the 2010 revised McDonald diagnostic criteria) within 2 years compared to T2 lesion count alone. There was no correlation between permeability and T2 lesion count. An increase in permeability in normal-appearing white matter of 0.1 ml/100 g/min increased the risk of multiple sclerosis 8.5 times whereas having more than nine T2 lesions increased the risk 52.6 times. Receiver operating characteristic curve analysis of permeability in normal-appearing white matter gave a cut-off of 0.13 ml/100 g/min, which predicted conversion to multiple sclerosis with a

    Full Text Available Background: Hamadan Province is one of the high-risk regions in Iran for Multiple sclerosis (MS. A majority of the epidemiological studies conducted in Iran addressing MS are descriptive. This study was conducted to assess MS and its associated risk factors in Hamadan Province, the west of Iran.Methods: This case-control study compared 100 patients with MS (case group and 100 patients with acute infectious diseases (control group from September 2013 to March 2014. A checklist was used to assess the demographic, medical, and family history of the patients. The Friedman-Rosenman questionnaire was also used to assess personality type. Statistical analysis was performed using logistic regression model with Stata 11 software program.Results: The adjusted odds ratio (OR estimate of MS was 4.37 (95% CI: 2.33, 8.20 for females compared to males; 0.15 (95% CI: 0.06, 0.43 for people aged above 50 years compared to aged 14 to 29 years; 0.44 (95% CI: 0.21, 0.91 for overweight or obese people compared to normal weights. Crude OR indicated a significant association between the occurrence of MS and exclusive breast feeding, season of birth, and smoking. However, the association was not statistically significant after adjustment for other covariates.Conclusion: The risk of MS is significantly lower in male gender, obese/overweight, and old people. Furthermore, non-smoking, non-exclusive breast-feeding, and born in autumn may increase the risk of MS but need further investigation. However, long-term large prospective cohort studies are needed to investigate the true effect of the potential risk factors on MS. Keywords: Multiple sclerosis, Risk factors, Case-control study, Iran

    Full Text Available Multiple sclerosis (MS is a chronic inflammatory disease of the central nervous system which is accompanied by considerable disability and high costs. This report summarises the evidence on effectiveness and costs of beta-interferons and natalizumab in the treatment of multiple sclerosis. The review included systematic reviews and randomised controlled trials (with an observation time of at least one year in patients with MS which assessed outcome parameters such as progression, exacerbations and adverse effects. An extensive literature search included databases such as MEDLINE, EMBASE, the Cochrane Library and various HTA-databases. Studies were selected according to predefined criteria, their quality was assessed according to criteria defined prospectively, and data were summarised systematically in tables. Cost-effectiveness evaluations were also included.Two systematic reviews and 24 randomised controlled trials of beta-interferon therapy were included, as well as three trials on the effectiveness of natalizumab. A total of 22 cost-effectiveness analyses for interferons were included, whereas no economic evaluations for natalizumab were identified. Use of interferon beta-1a or interferon beta-1b after a first demyelinating event led to a reduction of the conversion to definite MS during an observation time of two to three years. In relapsing remitting MS, interferon beta-1a reduced progression. The effects of interferon beta-1b on progression are unclear. Interferon beta-1a and interferon beta-1b reduced in some but not all studies outcomes relating to exacerbations. In direct comparison trials, interferon beta-1b (Betaferon® or Betaseron® and interferon beta-1a (Rebif®, higher dosage of 44 µg three subcutaneous injections per week proved superior to interferon beta-1a (Avonex®, 30 µg per week intramuscular with respect to exacerbation outcomes. For secondary progressive MS, only one of five studies found a reduced progression with

    Full Text Available We read with interest the article by Langer et al., describing the MRI findings in a neonatal patient with tuberous sclerosis. They describe the presence of periventricular white matter lesions in the centrum semiovale, with linear, circular, and semicircular shapes, with hyperintense margins, and isointense centers, and better seen on T1-weighted and T1 FLAIR sequences than on T2-weighted sequences. They propose that these "target"-like lesions have not been previously reported in patients with tuberous sclerosis."nWe believe that what Langer et al. are showing is unrelated to tuberous sclerosis itself, and represents additional classical MRI findings of acute periventricular leukomalacia and acute white matter injury.

    Multiple sclerosis(MS) is the most famous autoimmune disease attacking the central nervous system. It attacks people from age 20–50 years old and the females’ attacks double than males’ attacks. MS is an autoimmune disease affecting principally the central nervous system that cause nerve sheath demyelination followed by axon damage and paralysis. MS symptoms include muscle weakness, weak reflexes, muscle spasm, difficult in move, miss-coordination and unbalance with others. There are many factors may be responsible for MS: microbial, viral, smoking, stress, environmental toxins, contaminated diet, and gout. MS is wide spread in the populations in North Europe and this related to lack of vitamin D due to decrease of sunlight exposure. MS biomarkers include nitric oxide, interleukin-6, nitric oxide synthase, fetuin-A and osteopontin. MS is not a genetic disease where MS occurs when human leukocyte antigen system related genes are changed in chromosome 6. The physiology of MS is monitored by activation of immuneinflammatory, oxidative, and nitrosative stress pathways. MS is including two main steps:(1) myelin sheath destruction and formation of lesions and,(2) inflammation. Four types of MS can be distinguished: relapsing-remitting, primary progressive, secondary progressive and progressive relapsing. Nine treatments have been accepted for relapsingremitting MS type: interferon b-1a, interferon b-1b, mitoxantrone, natalizumab, glatiramer acetate, fingolimod, dimethyl fumarate, teriflunomide, and alemtuzumab, however,the only treatment used is mitoxantrone for progressive MS but many of MS treatments side effects are recorded. Complementary treatments also used in MS treatments such as:vitamin D, Yoga, medicinal plants, oxygen therapy, acupuncture and reflexology.

  1. Sphingolipids: Important Players in Multiple Sclerosis

    2014-06-01

    Full Text Available Multiple Sclerosis (MS is the most common cause for permanent disability in young adults. Current pathophysiological understanding has identified an autoaggressive immune reaction with infiltration of immune cells into the central nervous system and local inflammatory and demyelinating reactions. The current therapy focuses on a modulation or suppression of immune functions. Sphingolipids, main components of nervous tissue, have been linked to MS already 60 years ago with the description of an unusual myelin lipid distribution in diseased patients. There is tremendous information developing on the role of different sphingolipids in MS. Antibodies against sphingomyelin, sulfatide or galacosylceramide have been detected in serum or CSF of MS patients, although up to now, this knowledge did not find its way into clinical use. Ceramide and the enzymes linked to its production have been described to play a pivotal role in oligendrocyte damage and demyelination. Nowadays, especially sphingosine-1-phosphate (S1P is in the focus of pathophysiological research and therapy development. A S1P analogue, FTY720, is a widely distributed therapy against relapsing-remitting MS, attenuating the emigration of activated, autoreactive lymphocytes from lymph nodes, thereby preventing new inflammatory infiltration into the central nervous system. Beside, there is more and more evidence, that especially S1P receptors on oligodendrocytes and astrocytes are involved in demyelination processes and subsequent axonal degeneration, important features of chonic progressive MS disease course. Further information and research on the manifold role of sphingolipids are needed to prepare the ground for further clinical trials. This review focuses on the current knowledge of the role of sphingolipids in MS and describes the current therapeutical implications.

    Multiple sclerosis is a complex, heterogeneous disease associated with long-term disability. Despite the availability of advanced disease-modifying and symptomatic therapies that may decrease activity and progression of disease and alleviate complaints to a certain extent, there is still a need for comprehensive rehabilitation interventions in order to reduce sequels and symptoms of the disease on personal activities and social participation to achieve the highest possible independence and the best quality of life. Timing and setting of rehabilitation interventions should be selected individually depending on disease phase, functional deficits, personal requirements, as well as specific goals. In addition, limitations and disease-specific characteristics that may influence rehabilitation outcome should be noted. Rehabilitation interventions should be considered early for maintaining functional capacity and reducing risk for losing important abilities or independence. Due to gradual failure of adaptive compensatory mechanisms along the course of disease, benefits of rehabilitation interventions are generally higher in earlier phases of MS. Inpatient and outpatient multidisciplinary rehabilitation has been shown to be beneficial in improving disability, participation and quality of life despite progression of the disease. Good evidence exists for different specific interventions improving physical and cognitive performance. Other important issues responsible for beneficial effects of comprehensive rehabilitation in MS include education, instruction, and information of patients and caregivers. Comprehensive assessment of health domains in MS patients using standardized framework and common language for describing the impact of disease at different levels, using International Classification of Functioning, Disability and Health (ICF) core sets may increase the knowledge of needs of these patients for more efficient and adapted rehabilitation interventions meeting these

    Full Text Available BACKGROUND: Poor sleep is a frequent symptom in patients with multiple sclerosis (MS. Sleep may be influenced by MS-related symptoms and adverse effects from immunotherapy and symptomatic medications. We aimed to study the prevalence of poor sleep and the influence of socio-demographic and clinical factors on sleep quality in MS- patients. METHODS: A total of 90 MS patients and 108 sex-and age- matched controls were included in a questionnaire survey. Sleep complaints were evaluated by Pittsburgh Sleep Quality Index (PSQI and a global PSQI score was used to separate good sleepers (≤ 5 from poor sleepers (>5. Excessive daytime sleepiness, the use of immunotherapy and antidepressant drugs, symptoms of pain, depression, fatigue and MS-specific health related quality of life were registered. Results were compared between patients and controls and between good and poor sleepers among MS patients. RESULTS: MS patients reported a higher mean global PSQI score than controls (8.6 vs. 6.3, p = 0.001, and 67.1% of the MS patients compared to 43.9% of the controls (p = 0.002 were poor sleepers. Pain (p = 0.02, fatigue (p = 0.001, depression (p = 0.01 and female gender (p = 0.04 were associated with sleep disturbance. Multivariate analyses showed that female gender (p = 0.02, use of immunotherapy (p = 005 and a high psychological burden of MS (p = 0.001 were associated with poor sleep among MS patients. CONCLUSIONS: Poor sleep is common in patients with MS. Early identification and treatment of modifiable risk factors may improve sleep and quality of life in MS.

    Full Text Available Background:It has been suggested that nutrition might play a role in the etiology of multiple sclerosis (MS. However,dietary patterns associated with MS risk are unknown. This study was conducted to compare the dietary patterns of patients with MS and healthy controls to find the relationship between dietary patterns and MS.Methods:Usual dietary intake of 75 women with relapsing/remitting MS (RRMS and 75 healthy controls were assessed with a food frequency questionnaire consisting of 168 food items. To define major dietary patterns, we used factor analysis. Multivariate logistic regression was used to assess the relationship between dietary patterns and risk of MS.Results:Traditional pattern (high in low-fat dairy products,red meat, vegetable oil, onion, whole grain, soy, refined grains, organ meats, coffee, and legumes was inversely related to the risk of MS [odds ratio (OR = 0.15; 95%confidence interval (CI: 0.03-0.18; P = 0.028]. A similar inverse relationship was noted between MS risk andlacto-vegetarian (high in nuts, fruits, French fries, coffee,sweets and desserts, vegetables, and high-fat dairy products and vegetarian (high in green leafy vegetables, hydrogenated fats, tomato, yellow vegetables, fruit juices, onion, and other vegetablespatterns (OR = 0.31; 95% CI: 0.12-0.82; P = 0.018 and OR = 0.42; 95% CI: 0.19-0.90; P = 0.026, respectively. In contrast, the prevalence of MS was higher in those who had high animal fat dietary pattern (high in animal fats,potato, meat products, sugars, and hydrogenated fats and low in whole grains (OR = 1.99; 95% CI: 1.63-2.94;P < 0.005.Conclusion:Our findings showed that the risk of RRMS can be affected by major dietary patterns.

    Full Text Available Abstract Background Celiac disease (CD is a common systemic disease related to a permanent intolerance to gluten and is often associated with different autoimmune and neurological diseases. Its mean prevalence in the general population is 1-2% worldwide. Our aim was to study the prevalence of celiac disease in a prospective series of Multiple Sclerosis (MS patients and their first-degree relatives. Methods We analyzed the prevalence of serological, histological and genetic CD markers in a series of 72 MS patients and in their 126 first-degree relatives, compared to 123 healthy controls. Results Tissue IgA-anti-transglutaminase-2 antibodies were positive in 7 MS patients (10%, compared to 3 healthy controls (2.4% (p We detected mild or moderate villous atrophy (Marsh III type in duodenal biopsies, in 8 MS patients (11.1%. We also found a high proportion of CD among first-degree relatives: 23/126 (32%. Several associated diseases were detected, mainly dermatitis 41 (57% and iron deficiency anemia in 28 (39% MS patients. We also found in them, an increased frequency of circulating auto-antibodies such as anti-TPO in 19 (26%, ANA in 11 (15% and AMA in 2 (3%. Conclusions We have found an increased prevalence of CD in 8 of the 72 MS patients (11.1% and also in their first-degree relatives (23/126 [32%]. Therefore, increased efforts aimed at the early detection and dietary treatment of CD, among antibody-positive MS patients, are advisable.

  9. Anxiety in patients with multiple sclerosis.

    Riether, A M

    1999-04-01

    Anxiety disorders are quite common, and frequently overlooked, in patients with Multiple Sclerosis (MS). This is often due to the difficulty differentiating anxiety from personality correlates or reactive tendencies in patients with neurologic disease. This chapter offers the consulting psychiatrist guidelines for providing psychological support to patients with MS at various stages of their disease. DSM-IV-based differential diagnosis, psychotherapeutic techniques, behavioral interventions, and pharmacological support (including the newer alternative therapies) are reviewed. The physical, functional, and symbolic losses caused by this chronic and progressive disease are considered in the broader context of individual patients' lives. Particular attention has been given to specific pharmacological treatment of steroid-induced anxiety. This is essential knowledge for the consulting psychiatrist. The overlap between depressive symptoms, manic symptoms and cognitive changes in MS patients is reviewed with special emphasis on the structural correlates. Current neuro-imaging techniques, including emerging technologies such as gadolinium enhancement, single photon emission computed tomography and brain electrical mapping (BEAM), now provide a far more accurate view of brain damage in MS. This permits diagnosis of the disease much earlier, and is also beginning to show correlation between neuropsychiatric clinical findings, and the nature and location of demyelinating plaques in the brains of MS patients. This chapter seeks to clearly define the associations between anxiety disorders and cerebral involvement in MS patients, suggesting that common neurological and biochemical mechanisms are more extensive than generally suspected. It is hoped that this information will aid clinicians in more accurately diagnosing and effectively treating anxiety in MS patients.

    Highlights: •We demonstrated decreased connectivity between thalamus and cortical regions in MS. •Increased intra- and inter-thalamic connectivity was also observed in MS. •The increased functional connectivity is attenuated by increasing disease duration. -- Abstract: Objective: To compare thalamic functional connectivity (FC) in patients with multiple sclerosis (MS) and healthy controls (HC), and correlate these connectivity measures with other MRI and clinical variables. Methods: We employed resting-state functional MRI (fMRI) to examine changes in thalamic connectivity by comparing thirty-five patients with MS and 35 age- and sex-matched HC. Thalamic FC was investigated by correlating low frequency fMRI signal fluctuations in thalamic voxels with voxels in all other brain regions. Additionally thalamic volume fraction (TF), T2 lesion volume (T2LV), EDSS and disease duration were recorded and correlated with the FC changes. Results: MS patients were found to have a significantly lower TF than HC in bilateral thalami. Compared to HC, the MS group showed significantly decreased FC between thalamus and several brain regions including right middle frontal and parahippocampal gyri, and the left inferior parietal lobule. Increased intra- and inter-thalamic FC was observed in the MS group compared to HC. These FC alterations were not correlated with T2LV, thalamic volume or lesions. In the MS group, however, there was a negative correlation between disease duration and inter-thalamic connectivity (r = −0.59, p < 0.001). Conclusion: We demonstrated decreased FC between thalamus and several cortical regions, while increased intra- and inter-thalamic connectivity in MS patients. These complex functional changes reflect impairments and/or adaptations that are independent of T2LV, thalamic volume or presence of thalamic lesions. The negative correlation between disease duration and inter-thalamic connectivity could indicate an adaptive role of thalamus that is

    Full Text Available Acquired behavioral changes have essentially been described in advanced multiple sclerosis (MS. The present study was designed to determine whether behavioral modifications specifically related to the MS pathological process could be identified in the initial phase of the disease, as compared to control patients with chronic, relapsing and progressive inflammatory disorders not involving the central nervous system (CNS. Eighty-eight early MS patients (Expanded Disability Status Scale score ≤ 2.5 and 48 controls were tested. Perceived changes by informants in behavioral control, goal-directed behavior, decision making, emotional expression, insight and interpersonal relationships were assessed using the Iowa Scale of Personality Change (ISPC. Executive behavioral disturbances were screened using the Dysexecutive Questionnaire (DEX. The mean change between the premorbid and postmorbid ISPC ratings was similar in the MS [12.2 (SD 15.6] and in the control [11.5 (SD 15.1] group. The perceived behavioral changes (PBCs most frequently reported in both groups were lack of stamina, lability/moodiness, anxiety, vulnerability to stress and irritability. Pathological scores in the DEX were also similar in both groups. Correlations between PBCs and DEX scores were different in MS and control groups. MS patients with cognitive impairment had a marginally higher number of PBCs than control patients (p = 0.056 and a significantly higher DEXp score (p = 0.04. These results suggest that (1 PBCs occurring in early MS patients were not different from those induced by comparable chronic non-CNS disorders, (2 qualitative differences in the relationship between behavioral symptoms and executive-behavioral changes may exist between MS and control groups, and (3 behavioral symptoms seem associated with cognitive deficits in MS. We further plan to assess these observations longitudinally.

    During the past decades, better understanding of relapsing-remitting multiple sclerosis disease mechanisms have led to the development of several disease-modifying therapies, reducing relapse rates and severity, through immune system modulation or suppression. In contrast, current therapeutic options for progressive multiple sclerosis remain comparatively disappointing and challenging. One possible explanation is a lack of understanding of pathogenic mechanisms driving progressive multiple sclerosis. Furthermore, diagnosis is usually retrospective, based on history of gradual neurological worsening with or without occasional relapses, minor remissions or plateaus. In addition, imaging methods as well as biomarkers are not well established. Magnetic resonance imaging studies in progressive multiple sclerosis show decreased blood-brain barrier permeability, probably reflecting compartmentalization of inflammation behind a relatively intact blood-brain barrier. Interestingly, a spectrum of inflammatory cell types infiltrates the leptomeninges during subpial cortical demyelination. Indeed, recent magnetic resonance imaging studies show leptomeningeal contrast enhancement in subjects with progressive multiple sclerosis, possibly representing an in vivo marker of inflammation associated to subpial demyelination. Treatments for progressive disease depend on underlying mechanisms causing central nervous system damage. Immunity sheltered behind an intact blood-brain barrier, energy failure, and membrane channel dysfunction may be key processes in progressive disease. Interfering with these mechanisms may provide neuroprotection and prevent disability progression, while potentially restoring activity and conduction along damaged axons by repairing myelin. Although most previous clinical trials in progressive multiple sclerosis have yielded disappointing results, important lessons have been learnt, improving the design of novel ones. This review discusses mechanisms involved

    2016-03-23

    This is an update of the Cochrane review 'Memory rehabilitation for people with multiple sclerosis' (first published in the Cochrane Library 14 March 2012, Issue 3). Impairments in cognitive function, particularly memory, are common in people with multiple sclerosis (MS) and can potentially affect their ability to complete functional activities. There is evidence from single-case or small group studies that memory rehabilitation can be beneficial for people with MS, but findings from randomised controlled trials (RCTs) and systematic reviews have been inconclusive. To determine whether people with MS who received memory rehabilitation showed: 1. better outcomes in their memory functions compared to those given no treatment or receiving a placebo control; and 2. better functional abilities, in terms of activities of daily living, mood, and quality of life, than those who received no treatment or a placebo. We searched the Trials Specialised Register of the Cochrane Multiple Sclerosis and Rare Diseases of the CNS Group (2 June 2015) and the following electronic databases: The NIHR Clinical Research Network Portfolio database (NIHR CRN) (from 2010 to June 2015), The Allied and Complementary Medicine Database (AMED) (2010 to June 2015), British Nursing Index (BNI) (2010 to June 2015), PsycINFO (2011 to June 2015), and CAB Abstracts (2010 to June 2015). Start dates for the electronic databases coincided with the last search for the previous review. We handsearched relevant journals and reference lists. We selected RCTs or quasi-randomised trials of memory rehabilitation or cognitive rehabilitation for people with MS in which a memory rehabilitation treatment group was compared to a control group. Selection was conducted independently first and then confirmed through group discussion. We excluded studies that included participants whose memory deficits were the result of conditions other than MS unless we could identify a subgroup of participants with MS with separate

  14. Antibody producing B lineage cells invade the central nervous system predominantly at the time of and triggered by acute Epstein-Barr virus infection: A hypothesis on the origin of intrathecal immunoglobulin synthesis in multiple sclerosis.

    2016-06-01

    Patients with multiple sclerosis (MS), a chronic inflammatory disease of the central nervous system (CNS), typically have an intrathecal synthesis of immunoglobulin (Ig)G. Intrathecal IgG is produced by B lineage cells that entered the CNS, but why and when these cells invade the CNS of patients with MS is unknown. The intrathecal IgG response in patients with MS is polyspecific and part of it is directed against different common viruses (e.g. measles virus, rubella virus, varicella zoster virus). Strong and consistent evidence suggests an association of MS and Epstein-Barr virus (EBV) infection and EBV seroprevalence in patients with MS is practically 100%. However, intriguingly, despite of the universal EBV seroprevalence, the frequency of intrathecally produced IgG to EBV in patients with MS is much lower than that of intrathecally produced IgG to other common viruses. The acute phase of primary EBV infection is characterized by a strong polyclonal B cell activation. As typical for humoral immune responses against viruses, EBV specific IgG is produced only with a temporal delay after acute EBV infection. Aiming to put the above facts into a logical structure, we here propose the hypothesis that in individuals going on to develop MS antibody producing B lineage cells invade the CNS predominantly at the time of and triggered by acute primary EBV infection. Because at the time of acute EBV infection EBV IgG producing B lineage cells have not yet occurred, the hypothesis could explain the universal EBV seroprevalence and the low frequency of intrathecally produced IgG to EBV in patients with MS. Evidence supporting the hypothesis could be provided by large prospective follow-up studies of individuals with symptomatic primary EBV infection (infectious mononucleosis). Furthermore, the clarification of the molecular mechanism underlying an EBV induced invasion of B lineage cells into the CNS of individuals going on to develop MS could corroborate it, too. If true, our

    2013-11-01

    The strong rationale for cell-based therapy in multiple sclerosis is based on the ability of stem and precursor cells of neural and mesenchymal origin to attenuate neuroinflammation, to facilitate endogenous repair processes, and to participate directly in remyelination, if directed towards a myelin-forming fate. However, there are still major gaps in knowledge regarding induction of repair in chronic multiple sclerosis lesions, and whether transplanted cells can overcome the multiple environmental inhibitory factors which underlie the failure of endogenous repair. Major challenges in clinical translation include the determination of the optimal cellular platform, the route of cell delivery, and candidate patients for treatment.

  16. Therapeutic use of sport climbing for patients with multiple sclerosis

    Directory of Open Access Journals (Sweden)

    Ana Ožura

    2009-05-01

    Full Text Available Sport climbing is a form of exercise that requires complex and variable movement. Because of the use of the so-called "top-rope system", this is a safe activity appropriate for individuals with physical disabilities. Therefore, climbing might prove to be an effective form of therapy for patients with multiple sclerosis. Multiple sclerosis is a chronic neurological disease that may include motor and cognitive deficits as well as affective disturbances. The illness is characterized by multifocal areas of brain damage (plaques, as consequence of autoimmune inflammation. Sport climbing might be a potentially useful activity for treating spasticity, improving a person's self image and certain aspects of cognition, such as attention and executive functions, as well as for managing emotional disturbances. All of the above are areas where patients with multiple sclerosis might be in need of assistance. The article also describes the experience of a patient with multiple sclerosis who was enrolled in our climbing program. Future research is needed to evaluate the effect of climbing therapy for patients with multiple sclerosis.

    Multiple sclerosis patients who become pregnant experience a significant decrease in relapses that may be mediated by a shift in immune responses from T helper 1 to T helper 2. Animal models of multiple sclerosis have shown that the pregnancy hormone, estriol, can ameliorate disease and can cause an immune shift. We treated nonpregnant female multiple sclerosis patients with the pregnancy hormone estriol in an attempt to recapitulate the beneficial effect of pregnancy. As compared with pretreatment baseline, relapsing remitting patients treated with oral estriol (8 mg/day) demonstrated significant decreases in delayed type hypersensitivity responses to tetanus, interferon-gamma levels in peripheral blood mononuclear cells, and gadolinium enhancing lesion numbers and volumes on monthly cerebral magnetic resonance images. When estriol treatment was stopped, enhancing lesions increased to pretreatment levels. When estriol treatment was reinstituted, enhancing lesions again were significantly decreased. Based on these results, a larger, placebo-controlled trial of estriol is warranted in women with relapsing remitting multiple sclerosis. This novel treatment strategy of using pregnancy doses of estriol in multiple sclerosis has relevance to other autoimmune diseases that also improve during pregnancy.

  18. Symptomatic cranial neuralgias in multiple sclerosis: clinical features and treatment.

    2012-02-01

    In multiple sclerosis, neuropathic pain is a frequent condition, negatively influencing the overall quality of life. Cranial neuralgias, including trigeminal, glossopharyngeal neuralgias, as well as occipital neuralgia, are typical expression of neuropathic pain. Neuralgias are characterised by paroxysmal painful attacks of electric shock-like sensation, occurring spontaneously or evoked by innocuous stimuli in specific trigger areas. In multiple sclerosis, demyelination in the centrally myelinated part of the cranial nerve roots plays an important role in the origin of neuralgic pain. These painful syndromes arising in multiple sclerosis are therefore considered "symptomatic", in contrast to classic cranial neuralgias, in which no cause other than a neurovascular contact is identified. At this time, the evidence on the management of symptomatic cranial neuralgias in multiple sclerosis is fragmentary and a comprehensive review addressing this topic is still lacking. For that reason, treatment is often based on personal clinical experience as well as on anecdotal reports. The aim of this review is to critically summarise the latest findings regarding the pathogenesis, the diagnosis, the instrumental evaluation and the medical as well as neurosurgical treatment of symptomatic trigeminal, glossopharyngeal and occipital neuralgia in multiple sclerosis, providing useful insights for neurologists and neurosurgeons and a broad range of specialists potentially involved in the treatment of these painful syndromes.

    Inflammatory optic neuritis represents a frequent clinical situation in neurology and ophthalmology. In those parts of the world where multiple sclerosis is common, it is the condition most discussed as the cause of optic neuritis. However, the risk for conversion from optic neuritis to multiple sclerosis is evaluated at only around 50% after 15 years of follow-up. The risk is higher in cases in whom abnormalities typical of multiple sclerosis are found on magnetic resonance imaging of the brain and oligoclonal bands found on cerebrospinal fluid protein electrophoresis with no corresponding bands in serum. When these investigations are normal, optic neuritis is usually considered as "idiopathic" with a suspected viral aetiology, but in some cases, a systemic disease such as sarcoidosis, systemic lupus erythematosis, or Sjögren syndrome may be diagnosed. In rare cases, either recurrent optic neuritis or myelitis may occur without any evidence for multiple sclerosis. In the first case, it corresponds to a recently characterised disorder referred to as chronic relapsing inflammatory optic neuropathy and in the second case to a recently better identified entity, neuromyelitis optica. In the present paper, the differential diagnosis of inflammatory optic neuritis is presented from multiple sclerosis to infectious optic neuritis, systemic disease, and neuromyelitis optica.

    The immune system has crucial roles in the pathogenesis of multiple sclerosis. While the adaptive immune cell subsets, T and B cells, have been the main focus of immunological research in multiple sclerosis, it is now important to realize that the innate immune system also has a key involvement in regulating autoimmune responses in the central nervous system. Natural killer cells are innate lymphocytes that play vital roles in a diverse range of infections. There is evidence that they influence a number of autoimmune conditions. Recent studies in multiple sclerosis and its murine model, experimental autoimmune encephalomyelitis, are starting to provide some understanding of the role of natural killer cells in regulating inflammation in the central nervous system. Natural killer cells express a diverse range of polymorphic cell surface receptors, which interact with polymorphic ligands; this interaction controls the function and the activation status of the natural killer cell. In this review, we discuss evidence for the role of natural killer cells in multiple sclerosis and experimental autoimmune encephalomyelitis. We consider how a change in the balance of signals received by the natural killer cell influences its involvement in the ensuing immune response, in relation to multiple sclerosis.

  1. Symptomatic Therapy and Rehabilitation in Primary Progressive Multiple Sclerosis

    Full Text Available Multiple sclerosis (MS is an autoimmune inflammatory demyelinating disease of the central nervous system and a major cause of chronic neurological disability in young adults. Primary progressive MS (PPMS constitutes about 10% of cases, and is characterized by a steady decline in function with no acute attacks. The rate of deterioration from disease onset is more rapid than relapsing remitting and secondary progressive MS types. Multiple system involvement at onset and rapid early progression have a worse prognosis. PPMS can cause significant disability and impact on quality of life. Recent studies are biased in favour of relapsing remitting patients as treatment is now available for them and they are more likely to be seen at MS clinics. Since prognosis for PPMS is worse than other types of MS, the focus of rehabilitation is on managing disability and enhancing participation, and application of a “neuropalliative” approach as the disease progresses. This chapter presents the symptomatic treatment and rehabilitation for persons with MS, including PPMS. A multidisciplinary approach optimizes the intermediate and long-term medical, psychological and social outcomes in this population. Restoration and maintenance of functional independence and societal reintegration, and issues relating to quality of life are addressed in rehabilitation processes.

    Full Text Available Neuromyelitis optica spectrum disorder (NMOSD is a diverse condition which not only encompasses isolated longitudinally extensive transverse myelitis and optic neuritis but also includes area postrema syndrome, acute brainstem syndrome, symptomatic narcolepsy or acute diencephalic clinical syndrome, and symptomatic cerebral syndrome. Imaging may reveal periependymal lesions surrounding the ventricular system or involvement of corticospinal tracts, area postrema, diencephalon and corpus callosum. Rarely there may be hemispheric tumefactive lesions which enhance in a Cloud-like fashion on gadolinium injection unlike in tumefactive multiple sclerosis where there is incomplete ring enhancement. Here, we present a case of aquaporin-4 positive relapsing NMOSD who presented to us with recurrent episodes of paraperesis with longitudinally extensive transverse myelitis and tumefactive lesions of brain on imaging which enhanced in an incomplete ring like pattern resembling multiple sclerosis.

    It has been suggested that exercise (or physical activity) might have the potential to have an impact on multiple sclerosis (MS) pathology and thereby slow down the disease process in MS patients. The objective of this literature review was to identify the literature linking physical exercise (or...... activity) and MS disease progression. A systematic literature search was conducted in the following databases: PubMed, SweMed+, Embase, Cochrane Library, PEDro, SPORTDiscus and ISI Web of Science. Different methodological approaches to the problem have been applied including (1) longitudinal exercise......, (4) longitudinal exercise studies applying the experimental autoimmune encephalomyelitis (EAE) animal model of MS.

    Full Text Available   Background: Multiple sclerosis (MS and the gluten intolerance disease, celiac disease, (CD are immune-mediated diseases. Better testing for antibodies associated with CD, including anti-gliadin antibody [AGA], as well as anti-endomysial and anti-tissue transglutaminase antibodies, has improved the diagnosis of CD. Certain neurologic conditions have a reported association with CD. Previous researchers have investigated the role of a gluten-free diet in the treatment of MS and found no benefits. Here, we investigate the possible immunological association of CD with MS.Methods: Using ELISA, we estimated serum IgG and IgA anti-gliadin and IgA anti-endomysial antibodies in 34 MS patients, who were new or previous cases without immunosuppressant treatment for at least the last six months. The mean age was 29.6 years (range 15-46 years, with 30 patients relapsing-remitting, and four secondary-progressive MS. Thirty-four random anonymous blood donors were used as serologic controls (mean age 31.4 years, range 19-50 years. The individuals in both groups with elevated AGA (IgG or IgA or anti-endomysial antibody (IgA underwent duodenal biopsy.Results: In the MS group, high levels of IgG AGA were found in 5.9% of the subjects, and 5.9% had elevated IgA AGA. In the controls, elevated IgG AGA was detected in 5.9% of the subjects and IgA AGA in 2.9% (p=0.051 and 0.48, respectively. For IgG and IgA AGA levels, no significant differences were found between the patient and control groups. IgA anti-endomysial antibodies were not found in either group. Upon biopsy, the specific pathological features of celiac were absent.Conclusion: The same number of MS patients and controls had high levels of AGA, with normal levels of IgA anti-endomysial antibodies, which is more specific for CD, while the GI biopsies from both groups were not specific for CD. Therefore, AGA levels in any neurologic case should be interpreted with caution. The present study showed no

    Dopamine is a key neurotransmitter that induces critical effects in the nervous system and in many peripheral organs, via 5 dopamine receptors (DRs): D1R-D5R. Dopamine also induces many direct and very potent effects on many DR-expressing immune cells, primarily T cells and dendritic cells. In this review, we focus only on dopamine receptors, effects and production in T cells. Dopamine by itself (at an optimal concentration of~0.1 nM) induces multiple function of resting normal human T cells, among them: T cell adhesion, chemotactic migration, homing, cytokine secretion and others. Interestingly, dopamine activates resting effector T cells (Teffs), but suppresses regulatory T cells (Tregs), and both effects lead eventually to Teff activation. Dopamine-induced effects on T cells are dynamic, context-sensitive and determined by the: T cell activation state, T cell type, DR type, and dopamine concentration. Dopamine itself, and also few dopaminergic molecules/ drugs that are in clinical use for cardiac, neurological and other non-immune indications, have direct effects on human T cells (summarized in this review). These dopaminergic drugs include: dopamine = intropin, L-DOPA, bromocriptine, pramipexole, pergolide, haloperidol, pimozide, and amantadine. Other dopaminergic drugs were not yet tested for their direct effects on T cells. Extensive evidence in multiple sclerosis (MS) and experimental autoimmune encephalomyelitis (EAE) show dopaminergic dysregulations in T cells in these diseases: D1-like DRs are decreased in Teffs of MS patients, and dopamine does not affect these cells. In contrast, D1-like DRs are increased in Tregs of MS patients, possibly causing functional Treg impairment in MS. Treatment of MS patients with interferon β (IFN-β) increases D1-like DRs and decreases D2-like DRs in Teffs, decreases D1-like DRs in Tregs, and most important: restores responsiveness of patient's Teffs to dopamine. DR agonists and antagonists confer some benefits in

  7. A CASE STUDY OF BRAIN VOLUME REDUCTION IN MULTIPLE SCLEROSIS

    2013-07-01

    Full Text Available The development of sophisticated magnetic resonance imaging techniques and software for medical imaging processing and analysis has led to a significant progress in multiple sclerosis research and clinical care. The measurement of brain volumes provides a quantitative representation of damage, thus facilitating the objective follow-up process. The parameters obtained, though not being used routinely in clinical practice, are more and more often applied in clinical studies. The amount of whole brain and regional atrophy, estimated from serial scans, is considered important not only for disease progression, but also for cognitive dysfunction which is common in multiple sclerosis. In this paper we describe a volumetric study of two magnetic resonance scans of a patient with relapsing-remitting multiple sclerosis, performed 16 months one after the other, and analyzed using FSL SIENA software. Analysis demonstrated brain volume reduction of 1.7% between the two scans. We discuss the advantages of the method and its possible clinical applications.

    Full Text Available Objectives. To examine the association between fall history and physical activity using an objective measure of physical activity (i.e., accelerometry in persons with multiple sclerosis. Design. A community-based sample of 75 ambulatory persons with multiple sclerosis volunteered for the investigation. Participants self-reported fall history in the last year, underwent a neurological exam to determine Expanded Disability Status Scale (EDSS score, and wore an accelerometer around the waist for 7 consecutive days to determine physical activity. Results. Overall, 37 persons (49.3% of the sample reported falling in the last year with 28 of the 37 falling more than once. Persons who fell in the last year had a significantly lower number of steps/day than nonfallers (3510 versus 4940 steps/day; P.05. Conclusions. Collectively, the findings suggest that fall history may have little impact on current physical activity levels in persons with multiple sclerosis.

  10. Remyelination strategies in multiple sclerosis: a critical reflection.

    Science.gov (United States)

    Kipp, Markus

    2016-01-01

    Remyelination is the natural repair mechanism of demyelination and can be a highly efficient process in multiple sclerosis. However, in the majority of lesions, this regenerative approach is incomplete or fails. It is believed that remyelination protects against progressive axonal damage and thus long-term disability in patients with multiple sclerosis. For this reason, therapeutic promotion of remyelination represents an attractive option for preventing disease progression. In this editorial we casts a critical eye over the most frequently used experimental settings which aim to uncover potential remyelination promoting drugs. This article reflects upon the personal opinion of the author who currently used animal models allow to assess the potency of pharmacological interventions to accelerate, but not to induce myelin repair. Furthermore, it is discussed how remyelination and neuroprotection might well be two separate entities. Thus, induction of remyelination does not necessarily prevent disease progression in multiple sclerosis patients.

    Full Text Available Objective: this case report aims to demonstrate the diversity of clinical presentations, the symptoms evolution and the role of the primary care physician in the diagnosis and management of patients with multiple sclerosis, and their families. Case descriptions: two women, 31 and 28 years old, Caucasian, inserted within nuclear families (phases II and IV of the Duvall’ cycle, respectively belonging to the middle class of Graffar. The first one starts an insidious symptom of paraesthesia of the hands with improvement in 2 months. Within a year, she presents with difficulty raising the eyelids and marked imbalance. The second one presents sudden loss of visual acuity on the right, having been diagnosed with optic neuritis. Both were diagnosed with multiple sclerosis. Conclusion: multiple sclerosis is a chronic inflammatory, degenerative and demyelinating disease of the central nervous system that manifests heterogeneously. It is important for the family doctor to know how to deal with diagnostic uncertainties.

    Strokes are the main neurological manifestation of antiphospholipid syndrome. Other clinical presentations are possible and may mimic classic symptoms of multiple sclerosis (MS). A 46-year-old woman, with a history of two miscarriages, presented four subacute neurological episodes (optic neuritis, right facial paralysis, paraparesis of the thigh, and right brachial monoparesis). Using McDonald criteria, the diagnosis of multiple sclerosis was retained. Because of the occurrence of thrombocytopenia during a final relapse, we reconsidered the diagnosis of MS. Search for antiphospholipid antibodies was positive. All clinical manifestations and complementary tests were compatible with the diagnosis of antiphospholipid syndrome associated with multiple sclerosis. Given the great similarity of clinical, radiological and biological findings in the two diseases, non-thrombotic neurological manifestations of antiphospholipid syndrome can be difficult to distinguish from MS associated with antiphospholipid syndrome.

    The last 20 years have seen major progress in the treatment of relapsing-remitting multiple sclerosis (RRMS) using a variety of drugs targeting immune dysfunction. In contrast, all clinical trials of such agents in primary progressive multiple sclerosis (PPMS) have failed and there is limited evidence of their efficacy in secondary progressive disease. Evolving concepts of the complex interplay between inflammatory and neurodegenerative processes across the course of multiple sclerosis (MS) may explain this discrepancy. This paper will provide an up-to-date overview of the rationale and results of the published clinical trials that have sought to alter the trajectory of both primary and secondary MS, considering studies involving drugs with a primary immune target and also those aiming for neuroprotection. Future areas of study will be discussed, building on these results combined with the experience of treating RRMS and new concepts emerging from laboratory science and animal models.

    Natalizumab (NTZ) (Tysabri(®)) is a monoclonal antibody that inhibits leukocyte migration across the blood-brain barrier, thus reducing inflammation in central nervous system, and has been approved worldwide for the treatment of relapsing-remitting multiple sclerosis (RRMS). To evaluate the efficacy, tolerability and safety of NTZ in the treatment of patients with RRMS. We searched the Cochrane Multiple Sclerosis Group Trials Register, the Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library, 2010, Issue 1), MEDLINE (PubMed) and EMBASE, all up to 19 February 2010, and bibliographies of papers. Handsearching was carried out. Trialists and pharmaceutical companies were contacted. Furthermore, the websites of US Food and Drug Administration (FDA), the European Medicines Evaluation Agency (EMA) and the National Institute for health and Clinical Excellence (NICE) were also checked. All double-blind, randomised, controlled trials analysing more than a single infusion of NTZ (dosage > 3 mg/kg intravenous infusion every 4 weeks), also including its use as add-on treatment, versus placebo or other drugs in patients with RRMS. No restrictions on the basis of duration of treatment or length of follow up. Three reviewers independently selected articles which met the inclusion criteria. Disagreements were solved by discussion. Two reviewers independently extracted the data and assessed the methodological quality of each trial. Missing data was sought by contacting principal authors and Biogen Idec, through Biogen-Dompé Italia. Three studies met the inclusion criteria. These included one placebo-controlled trial (942 patients) and two add-on placebo-controlled trials, i.e. one plus glatiramer acetate (110 patients) and the second plus interferon beta-1a (1171 patients).This review assessed the efficacy, tolerability and safety of NTZ in patients with RRMS. Data was conclusive with respect to efficacy and tolerability, but not safety. As far as

    Directory of Open Access Journals (Sweden)

    Cecilia Rajda

    2015-08-01

    Full Text Available Multiple sclerosis is an inflammatory disease of the central nervous system, in which axonal transection takes place in parallel with acute inflammation to various, individual extents. The importance of the kynurenine pathway in the physiological functions and pathological processes of the nervous system has been extensively investigated, but it has additionally been implicated as having a regulatory function in the immune system. Alterations in the kynurenine pathway have been described in both preclinical and clinical investigations of multiple sclerosis. These observations led to the identification of potential therapeutic targets in multiple sclerosis, such as synthetic tryptophan analogs, endogenous tryptophan metabolites (e.g., cinnabarinic acid, structural analogs (laquinimod, teriflunomid, leflunomid and tranilast, indoleamine-2,3-dioxygenase inhibitors (1MT and berberine and kynurenine-3-monooxygenase inhibitors (nicotinylalanine and Ro 61-8048. The kynurenine pathway is a promising novel target via which to influence the immune system and to achieve neuroprotection, and further research is therefore needed with the aim of developing novel drugs for the treatment of multiple sclerosis and other autoimmune diseases.

    2013-12-01

    Symptomatic therapy of multiple sclerosis (MS) is an important part of a comprehensive treatment plan that aims to improve patients' quality of life. In the current era of medical progress, several factors have led to the development of guidelines for MS management. There is continued need for an evidence-based approach supported by high-quality data from controlled clinical trials. Most healthcare systems require this approach and include it in the reimbursement process. Guidelines are usually committed by national or continental neurological societies. The Spanish Society of Neurology demyelinating diseases working group has developed a consensus document on spasticity in patients with MS. MS experts from the group used the metaplan method to sum up the most important recommendations about spasticity for inclusion in the guidance. Recommendations were classified according to the Scottish Intercollegiate Guidelines Network system and approved by all members of the group. In Germany, the guideline panel of the German Neurological Society endorsed the national competence network for multiple sclerosis (Krankheitsbezogenes Kompetenznetz Multiple Sklerose) to update the existing recommendations. The most recent fifth edition of the guidelines (dated April 2012) now also includes recommendations for treatment of key symptoms such as spasticity. More than 30 MS neurologists contributed to the new edition reflecting the need for broad expertise. After a first round in which key topics were defined, a web-based decision process was undertaken to further develop individual topics such as symptomatic therapy. The draft manuscript was reviewed once again by the group prior to submission to the official review process. The aims of spasticity treatment are to improve mobility and dexterity, achieve physiological movement patterns, reduce pain, facilitate nursing measures and avoid complications such as contractures. Representative antispasticity medications include baclofen

    Drug development for multiple sclerosis (MS), as with any other neurological disease, faces numerous challenges, with many drugs failing at various stages of development. The disease-modifying therapies (DMTs) first introduced for MS are only moderately effective, but given the lack of competition, they have been widely accepted in clinical practice. Although safety and efficacy continue to be the two main metrics by which drugs will be judged, the newer agents in the market also face challenges of a more comparative nature-are they more efficacious than the currently available drugs on the market? Are they safer or better tolerated? Do they offer any practical advantages over current treatments? Fingolimod represented a milestone following its approval as an oral drug for MS in 2010, offering patients a far more convenient administration route. However, association with cardiovascular complications has led to a more cautious approach in its initial prescribing, now requiring cardiac monitoring for the first 6 h as well as subsequent monitoring of blood pressure and for macular oedema. Natalizumab, amongst licensed drugs, represents the current benchmark for efficacy. The risk of progressive multifocal leukoencephalopathy during natalizumab treatment is now more quantifiable. Other monoclonal antibodies are in various phases of development. Marketing authorisation for alemtuzumab has been filed, and whilst trial data suggest that its efficacy outperforms both licensed drugs and others in development, there is a significant risk of secondary autoimmunity. Its once-yearly administration, however, seems particularly advantageous. Rituximab is unlikely to be developed further as its license will expire, but ocrelizumab, another monoclonal antibody directly targeting B cells, is currently in phase 2 development and looks promising. Daclizumab is also moderately efficacious but may struggle to establish itself given its monthly subcutaneous dosing. There are new oral

    2012-02-01

    Relapsing-remitting multiple sclerosis (MS) has a highly variable clinical course but a number of demographic, clinical and MRI features can guide the clinician in the assessment of disease activity and likely disability outcome. It is also clear that the inflammatory activity in the first five years of relapsing-remitting MS results in the neurodegenerative changes seen in secondary progressive MS 10-15 years later. While conventional first-line disease modifying therapy has an effect on relapses, about one third of patients have a suboptimal response to treatment. With the advent of highly active second-line therapies with their evident marked suppression of inflammation, the clinician now has the tools to manage the course of relapsing-remitting MS more effectively. The development of treatment optimisation recommendations based on the clinical response to first-line therapies can guide the neurologist in more active management of the early course of relapsing-remitting MS, with the aim of preventing both acute inflammatory axonal injury and the neurodegenerative process which leads to secondary progressive MS.

    2012-11-01

    Full Text Available Multiple Sclerosis (MS is an inflammatory demyelinating neurodegenerative disorder of the brain and spinal cord that causes significant disability in young adults. Although the precise aetiopathogenesis of MS remains unresolved, its pathological hallmarks include inflammation, demyelination, axonal injury (acute and chronic, astrogliosis and variable remyelination. Despite major recent advances in therapeutics for the early stage of the disease there are currently no disease modifying treatments for the progressive stage of disease, whose pathological substrate is axonal degeneration. This represents the great and unmet clinical need in MS. Against this background, human stem cells offer promise both to improve understanding of disease mechanism(s through in-vitro modeling as well as potentially direct use to supplement and promote remyelination, an endogenous reparative process where entire myelin sheaths are restored to demyelinated axons. Conceptually, stem cells can act directly to myelinate axons or indirectly through different mechanisms to promote endogenous repair; importantly these two mechanisms of action are not mutually exclusive. We propose that discovery of novel methods to invoke or enhance remyelination in MS may be the most effective therapeutic strategy to limit axonal damage and instigate restoration of structure and function in this debilitating condition. Human stem cell derived neurons and glia, including patient specific cells derived through reprogramming, provide an unprecedented experimental system to model MS “in a dish” as well as enable high-throughput drug discovery. Finally, we speculate upon the potential role for stem cell based therapies in MS.

  4. Neural Plasticity in Multiple Sclerosis: The Functional and Molecular Background

    Directory of Open Access Journals (Sweden)

    Dominika Justyna Ksiazek-Winiarek

    2015-01-01

    Full Text Available Multiple sclerosis is an autoimmune neurodegenerative disorder resulting in motor dysfunction and cognitive decline. The inflammatory and neurodegenerative changes seen in the brains of MS patients lead to progressive disability and increasing brain atrophy. The most common type of MS is characterized by episodes of clinical exacerbations and remissions. This suggests the presence of compensating mechanisms for accumulating damage. Apart from the widely known repair mechanisms like remyelination, another important phenomenon is neuronal plasticity. Initially, neuroplasticity was connected with the developmental stages of life; however, there is now growing evidence confirming that structural and functional reorganization occurs throughout our lifetime. Several functional studies, utilizing such techniques as fMRI, TBS, or MRS, have provided valuable data about the presence of neuronal plasticity in MS patients. CNS ability to compensate for neuronal damage is most evident in RR-MS; however it has been shown that brain plasticity is also preserved in patients with substantial brain damage. Regardless of the numerous studies, the molecular background of neuronal plasticity in MS is still not well understood. Several factors, like IL-1β, BDNF, PDGF, or CB1Rs, have been implicated in functional recovery from the acute phase of MS and are thus considered as potential therapeutic targets.

  5. Multiple sclerosis animal models: a clinical and histopathological perspective.

    Kipp, Markus; Nyamoya, Stella; Hochstrasser, Tanja; Amor, Sandra

    There is a broad consensus that multiple sclerosis (MS) represents more than an inflammatory disease: it harbors several characteristic aspects of a classical neurodegenerative disorder, that is, damage to axons, synapses and nerve cell bodies. While we are equipped with appropriate therapeutic options to prevent immune-cell driven relapses, effective therapeutic options to prevent the progressing neurodegeneration are still missing. In this review article, we will discuss to what extent pathology of the progressive disease stage can be modeled in MS animal models. While acute and relapsing-remitting forms of experimental autoimmune encephalomyelitis (EAE), which are T cell dependent, are aptly suited to model relapsing-remitting phases of MS, other EAE models, especially the secondary progressive EAE stage in Biozzi ABH mice is better representing the secondary progressive phase of MS, which is refractory to many immune therapies. Besides EAE, the cuprizone model is rapidly gaining popularity to study the formation and progression of demyelinating CNS lesions without T cell involvement. Here, we discuss these two non-popular MS models. It is our aim to point out the pathological hallmarks of MS, and discuss which pathological aspects of the disease can be best studied in the various animal models available.

    Reduced protective immunity leads to viral persistence and demyelination in Theiler's murine encephalomyelitis. The aim of the present study was to compare the phenotype of brain-infiltrating leukocytes and cytokine expression in susceptible SJL and resistant C57BL/6 mice during Theilervirus-induced acute polioencephalitis. In contrast to C57/BL6 mice, SJL mice show an increased number of Foxp3(+) regulatory T cells and CD45R(+) B cells associated with delayed viral elimination and elevated IL-10 mRNA transcripts in the brain. Results substantiate the hypothesis that an imbalanced cytokine milieu during the early infection phase contributes to ineffective antiviral immunity in animals with a susceptible genetic background.

    In 26 patients with multiple sclerosis 100% responded abnormally to magnetic resonance imaging of the brain. Lesions in the posterior fossa were observed in 18 patients. The auditory brain stem response was abnormal in 15 patients, and 22 had abnormal immunoglobulins in the cerebrospinal fluid. The correlation between abnormalities of the auditory brain stem response and the magnetic resonance images was greatest in a subgroup where the two investigations were performed within a ten day interval. Results from magnetic resonance imaging, evoked potentials and cerebrospinal fluid investigations were used to reclassify 13 of 15 patients with clinically ''possible'' or ''probable''multiple sclerosis to a higher level using Poser's criteria. Evoked potentials (the auditory brain stem response in particular) correlated best with clinical multiple sclerosis category. The authors recommend that the magnetic resonance imaging is established as a first-hand investigation in evaluation of multiple sclerosis. Evoked potentials and cerebrospinal fluid investigations may prove to be more specific, however, and these investigations should also be performed as a routine. 23 refs., 2 figs., 2 tabs.

Lower-limb kinematics was evaluated by using a commercially available magnetic inertial measurement unit system. Mean and standard deviation of range of motion (mROM, sROM for each joint of lower limbs were calculated in one minute walking test. A motor performance index (E defined as the sum of sROMs was proposed.We established two novel observer-independent measures of disability. Hip mROM was extremely sensitive in measuring lower limb motor impairment, being correlated with muscle strength and also altered in patients without clinically detectable disability. On the other hand, E index discriminated patients according to disability, being altered only in patients with moderate and severe disability, regardless of walking speed. It was strongly correlated with fatigue and patient-perceived health status.Inertial sensor-based gait analysis is feasible and can detect clinical and subclinical disability in multiple sclerosis.

    Full Text Available The Amyotrophic lateral sclerosis (ALS is the most common form of motor neuron disease in the adulthood, and it is characterized by rapid and progressive compromise of the upper and lower motor neurons. The majority of the cases of ALS are classified as sporadic and, until now, a specific cause for these cases still is unknown. To present the different hypotheses on the etiology of ALS. It was carried out a search in the databases: Bireme, Scielo and Pubmed, in the period of 1987 to 2011, using the following keywords: Amyotrophic lateral sclerosis, motor neuron disease, etiology, causes and epidemiology and its similar in Portuguese and Spanish. It did not have consensus as regards the etiology of ALS. Researches demonstrates evidences as regards intoxication by heavy metals, environmental and occupational causes, genetic mutations (superoxide dismutase 1, certain viral infections and the accomplishment of vigorous physical activity for the development of the disease. There is still no consensus regarding the involved factors in the etiology of ALS. In this way, new research about these etiologies are necessary, for a better approach of the patients, promoting preventive programs for the disease and improving the quality of life of the patients.

    Background. Multiple sclerosis (MS) is an uncommon disease in multiracial Malaysia. Diagnosing patients with idiopathic inflammatory demyelinating diseases has been greatly aided by the evolution in diagnostic criterion, the identification of new biomarkers, and improved accessibility to neuroimaging in the country. Objectives. To investigate the spectrum of multiple sclerosis in Malaysia. Methods. Retrospective analysis with longitudinal follow-up of patients referred to a single tertiary medical center with neurology services in Malaysia. Results. Out of 245 patients with idiopathic inflammatory demyelinating disease, 104 patients had multiple sclerosis. Female to male ratio was 5 : 1. Mean age at onset was 28.6 ± 9.9 years. The Malays were the predominant racial group affected followed by the Chinese, Indians, and other indigenous groups. Subgroup analysis revealed more Chinese having neuromyelitis optica and its spectrum disorders rather than multiple sclerosis. Positive family history was reported in 5%. Optic neuritis and myelitis were the commonest presentations at onset of disease, and relapsing remitting course was the commonest disease pattern observed. Oligoclonal band positivity was 57.6%. At disease onset, 61.5% and 66.4% fulfilled the 2005 and 2010 McDonald's criteria for dissemination in space. Mean cord lesion length was 1.86 ± 1.65 vertebral segments in the relapsing remitting group as opposed to 6.25 ± 5.18 vertebral segments in patients with neuromyelitis optica and its spectrum disorders. Conclusion. The spectrum of multiple sclerosis in Malaysia has changed over the years. Further advancement in diagnostic criteria will no doubt continue to contribute to the evolution of this disease here.

    The Veterans Health Administration (VHA) has provided important contributions to our understanding of multiple sclerosis (MS); however, the characteristics of the modern VHA MS population have not been adequately characterized. Our objectives were to compare and contrast characteristics of the VHA MS population with other contemporary MS cohorts. A cross-sectional, mail-based survey of a stratified, random sample of 3,905 VHA users with MS was conducted. Detailed demographic and clinical data were collected as well as patient-reported outcomes assessing disability and quality of life. A total of 1,379 Veterans were enrolled into the MS Surveillance Registry (MSSR). Respondents did not differ from nonrespondents with regard to demographics or region. When compared to several other contemporary MS cohorts, some demographic differences were noted; however, the age of MS onset and diagnosis, subtype distribution, and most prevalent symptoms were very similar across MS cohorts. The MSSR appears to be representative of the general MS population. Combining the extensive VHA health services encounter data with the MSSR provides a rich and unique cohort for study.

    2016-11-23

    Multiple sclerosis is a major cause of neurological disability, which accrues predominantly during progressive forms of the disease. Although development of multifocal inflammatory lesions is the underlying pathological process in relapsing-remitting multiple sclerosis, the gradual accumulation of disability that characterises progressive multiple sclerosis seems to result more from diffuse immune mechanisms and neurodegeneration. As a result, the 14 anti-inflammatory drugs that have regulatory approval for treatment of relapsing-remitting multiple sclerosis have little or no efficacy in progressive multiple sclerosis without inflammatory lesion activity. Effective therapies for progressive multiple sclerosis that prevent worsening, reverse damage, and restore function are a major unmet need. In this Series paper we summarise the current status of therapy for progressive multiple sclerosis and outline prospects for the future.

  7. Immunotherapy of multiple sclerosis: the state of the art.

    2013-04-01

    It is widely accepted that the main common pathogenetic pathway in multiple sclerosis (MS) involves an immune-mediated cascade initiated in the peripheral immune system and targeting CNS myelin. Logically, therefore, the therapeutic approaches to the disease include modalities aiming at downregulation of the various immune elements that are involved in this immunologic cascade. Since the introduction of interferons in 1993, which were the first registered treatments for MS, huge steps have been made in the field of MS immunotherapy. More efficious and specific immunoactive drugs have been introduced and it appears that the increased specificity for MS of these new treatments is paralleled by greater efficacy. Unfortunately, this seemingly increased efficacy has been accompanied by more safety issues. The immunotherapeutic modalities can be divided into two main groups: those affecting the acute stages (relapses) of the disease and the long-term treatments that are aimed at preventing the appearance of relapses and the progression in disability. Immunomodulating treatments may also be classified according to the level of the 'immune axis' where they exert their main effect. Since, in MS, a neurodegenerative process runs in parallel and as a consequence of inflammation, early immune intervention is warranted to prevent progression of relapses of MS and the accumulation of disability. The use of neuroimaging (MRI) techniques that allow the detection of silent inflammatory activity of MS and neurodegeneration has provided an important tool for the substantiation of the clinical efficacy of treatments and the early diagnosis of MS. This review summarizes in detail the existing information on all the available immunotherapies for MS, old and new, classifies them according to their immunologic mechanisms of action and proposes a structured algorithm/therapeutic scheme for the management of the disease.

    We aimed to analyze the effects of progressive myelin loss and neurodegeneration seen in patients with multiple sclerosis (MS) on visual tract with electrophysiological and structural tests. Fifty-one patients diagnosed with MS in the Neurology Department were followed up in neuro-ophthalmology outpatient clinic irrespective of their visual symptoms, and were included in our study. The patients were classified as the ones with the history of optic neuritis (group II) and ones without the history (group I) of optic neuritis. The data, including clinical presentation, retinal nerve fiber layer thickness (RNFLT) measurements, pattern visual evoked potential (pVEP) and flash electro retino grams (ERG) test results, were recorded. In our study, comparison of pVEP test latencies of groups I and II with each other, and with those of healthy subjects revealed statistically significant differences (p  0.05). However, both groups showed significantly decreased cone b-wave amplitudes, elongation of latencies, and decreased flicker amplitudes on cone and flicker potentials obtained after light adaptation (p < 0.05). There was significant thinning in RNFLT of the both groups when compared to the normal standards. The difference between two groups was statistically significant (p < 0.05). Axon loss is seen in the optic nerve with subclinical or acute optic neuritis in patients with MS. RNFLT analysis and electrophysiological tests are of great importance in diagnosis of MS, as well as to determine progression and to direct neuroprotective therapy in patients diagnosed with MS. Objective analysis methods gain more importance in the diagnosis and follow-up of MS patients, parallel to technological advancements.

    Full Text Available Multiple Sclerosis is a multifactorial disease with several pathogenic mechanisms and pathways. Successful MS management and medical care requires early accurate diagnosis along with specific treatment protocols based upon multifunctional nanotechnology approach. This paper highlights advances in nanotechnology that have enabled the clinician to target the brain and CNS in patient with multiple sclerosis with nanoparticles having therapeutic and imaging components. The multipartite theranostic (thera(py + (diagnostics approach puts forth strong implications for medical care and cure in MS. The current nanotheranostics utilize tamed drug vehicles and contain cargo, targeting ligands, and imaging labels for delivery to specific tissues, cells, or subcellular components. A brief overview of nonsurgical nanorepair advances as future perspective is also described. Considering the potential inflammatory triggers in MS pathogenesis, a multifunctional nanotechnology approach will be needed for the prognosis.

    We describe a 32-year-old woman with sequential, severe, painless visual loss in one eye and then the other, and three temporally distinct episodes of neurological disturbance suggestive of demyelination in the spinal cord. She was positive for the T14484C mutation in the mitochondrial genome, one of three common mutations causing Leber's hereditary optic neuropathy. In addition, MRI identified areas of demyelination within the periventricular white matter of the brain and within the spinal cord. The coexistence of multiple sclerosis and Leber's hereditary optic neuropathy (Harding's syndrome) is known to occur more often than would be expected by chance; therefore, screening for the Leber's mutations in multiple sclerosis patients with severe visual loss should be considered because this has important prognostic and genetic implications.

    Background: There are many disabling medical conditions which can result in catastrophic health expenditure. Multiple Sclerosis is one of the most costly medical conditions through the world which encounter families to the catastrophic health expenditures. This study aims to investigate on what extent Multiple sclerosis patients face catastrophic costs. Method: This study was carried out in Ahvaz, Iran (2014). The study population included households that at least one of their members suffers from MS. To analyze data, Logit regression model was employed by using the default software STATA12. Results: 3.37% of families were encountered with catastrophic costs. Important variables including brand of drug, housing, income and health insurance were significantly correlated with catastrophic expenditure. Conclusions: This study suggests that although a small proportion of MS patients met the catastrophic health expenditure, mechanisms that pool risk and cost (e.g. health insurance) are required to protect them and improve financial and access equity in health care.

    Multiple sclerosis can affect pediatric patients. Our aim was to compare characteristics between pediatric-onset multiple sclerosis and adult-onset multiple sclerosis in Hispanic Americans. This was a cross-sectional analysis of 363 Hispanic American multiple scleroses cases; demographic and clinical characteristics were analyzed. A total of 110 Hispanic patients presented with multiple sclerosis before age 18 and 253 as adult multiple sclerosis. The most common presenting symptoms for both was optic neuritis. Polyfocal symptoms, seizures, and cognitive symptoms at presentation were more prevalent in pediatric-onset multiple sclerosis (P ≤ .001). Transverse myelitis was more frequent in adult-onset multiple sclerosis (P ≤ .001). Using multivariable analysis, pediatric-onset multiple sclerosis (adjusted odds ratio, 0.3OR 95% confidence interval 0.16-0.71, P = .004) and being US born (adjusted odds ratio, 0.553, 95% confidence interval 0.3-1.03, P = .006) were less likely to have severe ambulatory disability. Results suggest that pediatric-onset multiple sclerosis and adult-onset multiple sclerosis in Hispanics have differences that could be important for treatment and prognosis.

    We describe a case with simultaneous occurrence of cluster headache-like pain and multiple sclerosis. Both neuroimaging and neurophysiology (trigeminal evoked potentials) revealed a demyelination plaque in the pons, at the trigeminal root entry zone, on the side of pain. Although that type of lesion is usually associated with trigeminal neuralgia pain, we hypothesize that in this case it may be linked with the concomitant cluster headache, possibly by activation of trigemino-vascular mechanisms.

Despite treatment, a relevant proportion of patients continue to experience clinical (ie, relapses, worsening of disability and magnetic resonance imaging (MRI activity. Early identification of responders and nonresponders to interferon beta is strongly recommended to select patients who need a prompt switch to another disease-modifying agent and to ultimately avoid accumulation of fixed disability over time. Detecting responders and nonresponders to interferon beta can be challenging, mainly because of the lack of a clear and shared clinical definition of response to treatment. Clinical features at the start of treatment should be considered as prognostic factors, but MRI parameters assessed during treatment, such as contrast-enhancing lesions or new T2-hyperintense lesions, may be sensitive markers of response to interferon beta. Quantitative scoring systems derived from a combination of relapses and MRI activity have recently been proposed as practical tools for use in the everyday clinical setting. Blood biomarkers, such as neutralizing antibodies to interferon beta and Myxovirus resistance protein A, provide further useful information for detecting responders and nonresponders to interferon beta. However, since the presence of neutralizing antibodies can only partially explain the nonresponse to interferon beta, biomarkers of interferon beta activity possibly related to the pathogenesis of the disease could represent a future step toward a tailored, long-lasting effective treatment against multiple sclerosis

    The paper reviews service initiatives designed to facilitate job retention for employees with multiple sclerosis (MS). The thesis is that worksite barriers must be removed via reasonable accommodations for persons with MS to continue working as the illness progresses. Key elements of barrier removal include (a) needs assessments, (b) civil rights information concerning Title I of the Americans with Disabilities Act, (c) training on how to request reasonable accommodations from one's employer, and (d) consultation with employers.

    Microvesicles are a recently described way of cell communication that has been implicated in a number of biological processes, including neuroinflammation. Widely investigated as biomarkers in oncology and neurological disorders, little is known of the role of microvesicles in the pathogenesis of diseases such as multiple sclerosis (MS). Several evidences suggest that pro-inflammatory microglia and infiltrating macrophages release microvesicles that spread inflammatory signals and alter neuro...

    Several observations indicate that a retrovirus might be involved in the pathogenesis of multiple sclerosis (MS). We report that the sera from 40 Italian MS patients did not contain antibodies to the human T-lymphotropic type I (HTLV-I) and type III viruses (HTLV-III) at levels detectable by commercial ELISA kits. Nevertheless, it cannot be ruled out that a distinct retrovirus is the etiologic factor of MS.

    Multiple sclerosis has steadily increased in Mexican mestizos from an apparently rare disorder in the 1970s to the second most frequent cause of admission to a neurology ward in the 1990s. Most patients belonged to high socioeconomic and educational groups. Familial incidence was low. Age at onset was younger than in other series and long term disability was milder than in patients from countries in which the disease is apparently more prevalent.

    Full Text Available Background. Multiple sclerosis (MS disease course is known to be adversely affected by several factors including stress. A proposed mechanism for decreasing stress and therefore decreasing MS morbidity and improving quality of life is meditation. This review aims to critically analyse the current literature regarding meditation and MS. Methods. Four major databases were used to search for English language papers published before March 2014 with the terms MS, multiple sclerosis, meditation, and mindfulness. Results. 12 pieces of primary literature fitting the selection criteria were selected: two were randomised controlled studies, four were cohort studies, and six were surveys. The current literature varies in quality; however common positive effects of meditation include improved quality of life (QOL and improved coping skills. Conclusion. All studies suggest possible benefit to the use of meditation as an adjunct to the management of multiple sclerosis. Additional rigorous clinical trials are required to validate the existing findings and determine if meditation has an impact on disease course over time.

It frequently affects females in their reproductive phase of life. Therefore, family planning, pregnancy, and breastfeeding are important issues in the management of MS, particularly with respect to counseling and drug treatment. This paper reviews currently available data on the outcome of pregnancies in MS patients and the influence of pregnancy on the course of the disease. We give an update on the use of various disease-modifying MS drugs during pregnancy and breastfeeding. In addition to established therapies such as interferon-β, glatiramer acetate, natalizumab, and fingolimod, we also discuss the state of knowledge about new agents such as dimethyl fumarate, teriflunomide, and alemtuzumab in the context of pregnancy and breastfeeding.Keywords: multiple sclerosis, pregnancy, lactation, disease-modifying therapy

    To provide a definitive linkage map for multiple sclerosis, we have genotyped the Illumina BeadArray linkage mapping panel (version 4) in a data set of 730 multiplex families of Northern European descent. After the application of stringent quality thresholds, data from 4,506 markers in 2,692 individuals were included in the analysis. Multipoint nonparametric linkage analysis revealed highly significant linkage in the major histocompatibility complex (MHC) on chromosome 6p21 (maximum LOD score [MLS] 11.66) and suggestive linkage on chromosomes 17q23 (MLS 2.45) and 5q33 (MLS 2.18). This set of markers achieved a mean information extraction of 79.3% across the genome, with a Mendelian inconsistency rate of only 0.002%. Stratification based on carriage of the multiple sclerosis-associated DRB1*1501 allele failed to identify any other region of linkage with genomewide significance. However, ordered-subset analysis suggested that there may be an additional locus on chromosome 19p13 that acts independent of the main MHC locus. These data illustrate the substantial increase in power that can be achieved with use of the latest tools emerging from the Human Genome Project and indicate that future attempts to systematically identify susceptibility genes for multiple sclerosis will have to involve large sample sizes and an association-based methodology.

    Full Text Available Background: The etiology of multiple sclerosis (MS, a chronic demyelinative disease-is unknown. The damage of blood–brain barrier (BBB vasculature is a characteristic of MS and Homocystein (Hcy can damage BBB, then increase in total Hcy may be important in MS pathogenesis. The aim of this study was to compare the serum level of total Hcy in MS patients with control group. Methods: In a case control study, serum level of total Hcy measured in 35 MS patient and compared with 30 healthy matched controls. All patients had definitive MS according to Poser criteria, without history of myocardial infarction, stroke, neuropathy, transient ischemic attack, homocystinuria or renal failure. Results: The serum concentration of total homocystein was significantly higher in multiple sclerosis patients than healthy controls. The mean total Hcy level was 17.92± 6.9 mmol/lit in cases and 14.6±2.92 mmol/lit in controls (P=0.013. Conclusion: Serum total Homocystein may have a role in MS pathogenesis and reduction of it should be studied moreover. Key words: Multiple Sclerosis, Homocystein, Serum level

  4. Acquired sexual paraphilia in patients with multiple sclerosis.

    Sexual dysfunction in patients with multiple sclerosis is typically characterized by diminished libido, erectile and ejaculatory dysfunction in men, and poor lubrication and anorgasmy in women. In contrast, hypersexual behavior and paraphilias are distinctly uncommon in this population of patients, but have been associated with various focal brain lesions. We describe a man with clinically definite multiple sclerosis who developed profound and abrupt disinhibition and paraphilic behavior during an exacerbation. Neuroimaging revealed a marked increase in the number of enhancing lesions in the right sides of the hypothalamus and mesencephalon and extending into the right sides of the red nucleus, substantia nigra, and internal capsule. The altered sexual behavior was characterized by an obsessive and insatiable desire to touch women's breasts. Acquired sexual paraphilic behavior is uncommon in patients with multiple sclerosis but may occur when inflammatory demyelination involves the hypothalamic and septal regions of the basal prosencephalon. Our experience with this man illustrates the great difficulty involved in treating such patients when the paraphilic behavior becomes persistent.

  5. Meningeal and cortical grey matter pathology in multiple sclerosis

    Gh Popescu Bogdan F

    2012-03-01

    Full Text Available Abstract Although historically considered a disease primarily affecting the white matter of the central nervous system, recent pathological and imaging studies have established that cortical demyelination is common in multiple sclerosis and more extensive than previously appreciated. Subpial, intracortical and leukocortical lesions are the three cortical lesion types described in the cerebral and cerebellar cortices of patients with multiple sclerosis. Cortical demyelination may be the pathological substrate of progression, and an important pathologic correlate of irreversible disability, epilepsy and cognitive impairment. Cortical lesions of chronic progressive multiple sclerosis patients are characterized by a dominant effector cell population of microglia, by the absence of macrophagic and leukocytic inflammatory infiltrates, and may be driven in part by organized meningeal inflammatory infiltrates. Cortical demyelination is also present and common in early MS, is topographically associated with prominent meningeal inflammation and may even precede the appearance of classic white matter plaques in some MS patients. However, the pathology of early cortical lesions is different than that of chronic MS in the sense that early cortical lesions are highly inflammatory, suggesting that neurodegeneration in MS occurs on an inflammatory background and raising interesting questions regarding the role of cortical demyelination and meningeal inflammation in initiating and perpetuating the disease process in early MS.

  6. Neuroprotection in a novel mouse model of multiple sclerosis.

    Directory of Open Access Journals (Sweden)

    Katie Lidster

    Full Text Available Multiple sclerosis is an immune-mediated, demyelinating and neurodegenerative disease that currently lacks any neuroprotective treatments. Innovative neuroprotective trial designs are required to hasten the translational process of drug development. An ideal target to monitor the efficacy of strategies aimed at treating multiple sclerosis is the visual system, which is the most accessible part of the human central nervous system. A novel C57BL/6 mouse line was generated that expressed transgenes for a myelin oligodendrocyte glycoprotein-specific T cell receptor and a retinal ganglion cell restricted-Thy1 promoter-controlled cyan fluorescent protein. This model develops spontaneous or induced optic neuritis, in the absence of paralytic disease normally associated with most rodent autoimmune models of multiple sclerosis. Demyelination and neurodegeneration could be monitored longitudinally in the living animal using electrophysiology, visual sensitivity, confocal scanning laser ophthalmoscopy and optical coherence tomography all of which are relevant to human trials. This model offers many advantages, from a 3Rs, economic and scientific perspective, over classical experimental autoimmune encephalomyelitis models that are associated with substantial suffering of animals. Optic neuritis in this model led to inflammatory damage of axons in the optic nerve and subsequent loss of retinal ganglion cells in the retina. This was inhibited by the systemic administration of a sodium channel blocker (oxcarbazepine or intraocular treatment with siRNA targeting caspase-2. These novel approaches have relevance to the future treatment of neurodegeneration of MS, which has so far evaded treatment.

  7. Role of statins in the treatment of multiple sclerosis.

    Ciurleo, Rosella; Bramanti, Placido; Marino, Silvia

    2014-09-01

    Statins as inhibitors of 3-hydroxy-3-methylglutaryl coenzyme A reductase are widely prescribed for hypercholesterolemia treatment. In the last years, statins have also been shown to exert immunomodulatory and anti-inflammatory effects which appear to be related to inhibition of isoprenylation of small GTP-binding proteins and, at least in part, independent of their cholesterol-lowering effects. These "pleiotropic" effects make statins an attractive treatment option for immune-mediated disorders such as multiple sclerosis. Studies in vitro and in experimental autoimmune encephalomyelitis animal model seem to support not only the efficacy of statins as immunomodulatory agents but also their potential neuroprotective properties, although the exact mechanism with which statins exert these effects has not yet been fully understood. The immunomodulatory, anti-inflammatory and neuroprotective properties of statins provided the incentive for several clinical trials in multiple sclerosis, in which they were tested not only as mono-therapy but also in combination with interferon-β. However, the attempt to translate the results of animal model studies in humans produced conflicting results. Further large, prospective, randomized, double-blind, placebo-controlled trials, designed to evaluate the long-term effects of statins alone or in add-on to other disease-modifying therapies, are needed to support their routine clinical use in multiple sclerosis.

    Multiple sclerosis is an inflammatory disease involving the occurrence of demyelinating, chronic neurodegenerative lesions in the central nervous system. We studied vestibular evoked myogenic potentials (VEMPs) in this pathology, to allow us to evaluate the saccule, inferior vestibular nerve and vestibular-spinal pathway non-invasively. There were 23 patients diagnosed with multiple sclerosis who underwent VEMP recordings, comparing our results with a control group consisting of 35 healthy subjects. We registered p13 and n23 wave latencies, interaural amplitude difference and asymmetry ratio between both ears. Subjects also underwent an otoscopy and audiometric examination. The prolongation of p13 and n23 wave latencies was the most notable characteristic, with a mean p13 wave latency of 19.53 milliseconds and a mean latency of 30.06 milliseconds for n23. In contrast, the asymmetry index showed no significant differences with our control group. In case of multiple sclerosis, the prolongation of the p13 and n23 VEMP wave latencies is a feature that has been attributed to slowing of conduction by demyelination of the vestibular-spinal pathway. In this regard, alteration of the response or lack thereof in these potentials has a locator value of injury to the lower brainstem. Copyright © 2013 Elsevier España, S.L. All rights reserved.

    2008-08-13

    An immunological function has been proposed for the choroid plexus (CP). In multiple sclerosis (MS) brains, CPs show (immunohistochemistry to HLA-DR, CD3, CD20, CD68, VCAM-1, CD138) T lymphocytes in vessels and stroma, VCAM-1 expression on endothelia, intense HLA-DR immunostaining on cells in CP stroma, among CP epithelium and on epiplexus cells. CPs in control or amyotrophic lateral sclerosis brains do not show such inflammatory changes. Intense CP inflammation is observed in viral encephalitis. Changes in MS CPs suggest persisting immune activation, with intensity similar to acute encephalitis, even in MS phases in which neurodegeneration prevails. In MS, CPs could represent a site for lymphocyte entry in the CSF and for CSF antigens presentation.

    2013-01-23

    We report a 55-year-old patient, presenting with paresis, muscle atrophy and dysarthria, all symptoms accordable to definite amyotrophic lateral sclerosis (ALS). However, MRI and cerebrospinal fluid show abnormalities typical of multiple sclerosis (MS). On the basis of this case report, we discuss possible overlaps between both diseases by comparing clinical and paraclinical features including laboratory, radiological and electrophysiological diagnostics. As genetic, as well as environmental, factors are assumed to be involved in the development of both the diseases, literature is reviewed according to similar cases, results of autopsies and possible parallels in pathogenesis. In summary, based on the data currently available, the hypothesis of ALS being a neurodegenerative multisystem disorder, a common pathophysiological pathway or, alternatively, a random comorbidity of ALS and MS in this patient has to be discussed.

    Paroxysmal dysarthria (PD) and paroxysmal dysarthria-ataxia (PDA) syndromes are uncommon symptoms of the neurological dysfunction in multiple sclerosis (MS). We describe two patients who had clinically definite MS presented with symptomatic PD and PDA syndromes, respectively, related to demyelinating lesions. In one patient, the PD symptom was the initial manifestation of an acute episode. In the other patient, the episode of dysarthria was accompanied by ataxia disorders. Both patients had midbrain lesions at or below the level of the right red nucleus on magnetic resonance imaging (MRI), confirming that this area is critically involved. Both responded well to carbamazepine (CBZ).

    Psychological stress can negatively impact multiple sclerosis. To further understand how stress is addressed in the multiple sclerosis medical visit, 34 people with multiple sclerosis participated in focus groups. Transcripts were analyzed by inductive thematic analysis. The majority of participants did not discuss stress with their provider, citing barriers to communication such as lack of time, poor coordination between specialties, physician reliance on pharmaceutical prescription, and patient lack of self-advocacy. Participants recommended several ways to better manage psychological well-being in the clinical setting. These findings provide a foundation for future studies aimed at minimizing the detrimental effect of stress in multiple sclerosis. © The Author(s) 2014.

    Trigeminal root entry zone abnormality on brain magnetic resonance imaging has been frequently reported in multiple sclerosis patients, but it has not been investigated in neuromyelitis optica patients. Brain magnetic resonance imaging of 128 consecutive multiple sclerosis patients and 46 neuromyelitis optica patients was evaluated. Trigeminal root entry zone abnormality was present in 11 (8.6%) of the multiple sclerosis patients and two (4.3%) of the neuromyelitis optica patients. The pontine trigeminal root entry zone may be involved in both multiple sclerosis and neuromyelitis optica.

    Full Text Available It was determined earlier (G.P. Ivanova, 2012 that a chronic course of leukoencephalitis in teenagers caused by inadequate response of cytokine system to the combination of two herpesviruses (HV — EBV and HHV-6, leads to the development of multiple sclerosis (MS in 44% of cases. The research objective was to characterize the cytokine response in children with MS with simultaneous screening of the presence of active HV infections. 39 children with the diagnosis “MS” were under observation, 34 of them had relapsing-remitting (RR MS, and 5 children had a progressing course of MS (PMS. Concentration of cytokines IL-1β, IL-6, IL-8, IL-10, IFNα, IFNγ, and IL-4 was identified in blood serum and cerebrospinal liquid (CSF by enzyme-linked immunosorbent assay, HV DNA was revealed by PCR. Cytokine status in children with MS had some differences depending on the phase of the disease, clinical severity of the relapse and the course of MS. The relapse phase of RRMS was associated with the accumulation of IL-8, IL-10, and IL-6 in the blood, and index IFNγ/IL-4 modulations in accordance with the clinical severity of the relapse. A severe aggravation of the disease in children with PMS was accompanied by the increase of IL-8 system response. HV DNA was revealed in 27 patients from 39 ones (69% in blood and in 17 patients (44% in CSF with the predominance of EBV (93%, frequently in combination with HHV-6. During an acute period the frequency of HV DNA identification increased 2–3 times to compare with the remission period. Unlike children with RRMS, a mixed-infection of 3–4 herpes viruses was revealed in all 5 patients with PMS. According to the results summary it is possible to make a conclusion that HV-infection has an important role in MS pathogenesis in teenagers, taking part in the aggravation and progression of the disease by its effect on the cytokine system response. EBV-infection dominates among HV, however the risk of MS development

This survey evaluated neurologists’ perception of treatment adherence among MS patients.Materials and methods: This questionnaire-based survey of Belgian neurologists treating MS patients was conducted between June and July 2014. Face-to-face interviews with the neurologists were based on a semistructured questionnaire containing questions regarding the perception of the treatment-adherence level.Results: A total of 41 neurologists participated in the survey. Of these, 88% indicated frequent discussions about treatment adherence as beneficial for treatment efficacy. The mean time spent on the treatment-adherence discussion during the initial consultation was 11 minutes, with 24% of doctors spending 5 minutes and 24% of doctors spending 10 minutes discussing this issue. The majority of neurologists (56% perceived the adherence level in MS as good, and 12% perceived it as excellent. The majority of neurologists (64% indicated intolerance as a main cause of poor adherence, and all neurologists reported insufficient efficacy as a consequence of nonadherence. The importance of adherence in the neurologists’ practice was evaluated on a scale of 1–10, with 1= “not very important” and 10= “very important”: 44% of doctors indicated a score of 10, and the mean score was 9.0.Conclusion: Belgian neurologists consider treatment adherence in MS as essential for the benefits of therapies. However, although neurologists are aware of the consequences of nonadherence, they generally spend limited time discussing the importance of treatment adherence with their patients.

    Multiple sclerosis (MS) is a chronic disease of central nervous system. The multiple sclerosis information system (MSIS), such as other information system (IS), depends on identification, collection and processing of data for producing useful information. Lack of the integrated IS for collecting standard data causes undesirable effects on exchanging, comparing, and managing. The aim of this study was to recognize the role of the IS in the MS management and determine the advantages and barriers in implementing of the MSIS. The present study was a nonsystematized review that was done in order to recognize the role of the IS in the MS management. In this study, electronic scientific resources such as scientific magazines and books and published topics at conferences were used. We used key words (IS, chronic disease management, and multiple sclerosis), their combination or their synonyms in title, key words, abstracts, and text of English articles and published reports from 1980 until 2013, and by using search engines such as Google, Google Scholar and scientific databases and electronic issues such as iPubMed, sufficiently important difference, Scopus, Medlib, and Magiran for gathering information. More than 200 articles and reports were collected and assessed and 139 of them. Findings showed that the MSIS can reduce of disease expenses through continuously collecting correct, accurate, sufficient, and timely patients and disease nature information; recoding; editing; processing; exchanging, and distributing among different health care centers. Although the MSIS has many advantages; but, we cannot ignore cultural, economic, technical, organizational, and managerial barriers. Therefore, it is necessary to do studies for preventing, reducing, and controlling them. One of the ways is to recognize the advantages of the MSIS and usage information technology in optimizing disease management.

  5. The role of astrocytes in Multiple Sclerosis progression

    2015-08-01

    Full Text Available Multiple sclerosis is an inflammatory disorder causing central nervous system demyelination and axonal injury. Although its etiology remains elusive, several lines of evidence support the concept that autoimmunity plays a major role in disease pathogenesis.The course ofMS is highly variable; nevertheless, the majority of patients initially present a relapsing-remitting clinical course. After 10-15 years of disease, this pattern becomes progressive in up to 50% of untreated patients, during which time clinical symptoms slowly cause constant deterioration over a period of many years. In about 15% of MS patients however, disease progression is relentless from disease onset. Published evidence supports the concept that progressive multiple sclerosis reflects a poorly understood mechanism of insidious axonal degeneration and neuronal loss. Recently, the type of microglial cell and of astrocyte activation and proliferation observed has suggested contribution of resident central nervous system cells may play a critical role in disease progression. Astrocytes could contribute to this process through several mechanisms: a as part of the innate immune system, b as a source of cytotoxic factors, c inhibiting re-myelination and axonal regeneration by forming a glial scar, and d contributing to axonal mitochondrial dysfunction. Furthermore, regulatory mechanisms mediated by astrocytes can be affected by aging. Notably, astrocytes might also limit the detrimental effects of pro-inflammatory factors, while providing support and protection for oligodendrocytes and neurons. Because of the dichotomy observed in astrocytic effects, the design of therapeutic strategies targeting astrocytes becomes a challenging endeavor. Better knowledge of molecular and functional properties of astrocytes therefore, should promote understanding of their specific role in multiple sclerosis pathophysiology, and consequently lead to development of novel and more successful

    Background An evolving understanding of the immunopathogenesis of multiple sclerosis suggests that depleting B cells could be useful for treatment. We studied ocrelizumab, a humanized monoclonal antibody that selectively depletes CD20-expressing B cells, in the primary progressive form of the disease. Methods In this phase 3 trial, we randomly assigned 732 patients with primary progressive multiple sclerosis in a 2:1 ratio to receive intravenous ocrelizumab (600 mg) or placebo every 24 weeks for at least 120 weeks and until a prespecified number of confirmed disability progression events had occurred. The primary end point was the percentage of patients with disability progression confirmed at 12 weeks in a time-to-event analysis. Results The percentage of patients with 12-week confirmed disability progression was 32.9% with ocrelizumab versus 39.3% with placebo (hazard ratio, 0.76; 95% confidence interval [CI], 0.59 to 0.98; P=0.03). The percentage of patients with 24-week confirmed disability progression was 29.6% with ocrelizumab versus 35.7% with placebo (hazard ratio, 0.75; 95% CI, 0.58 to 0.98; P=0.04). By week 120, performance on the timed 25-foot walk worsened by 38.9% with ocrelizumab versus 55.1% with placebo (P=0.04); the total volume of brain lesions on T2-weighted magnetic resonance imaging (MRI) decreased by 3.4% with ocrelizumab and increased by 7.4% with placebo (Pprogressive multiple sclerosis, ocrelizumab was associated with lower rates of clinical and MRI progression than placebo. Extended observation is required to determine the long-term safety and efficacy of ocrelizumab. (Funded by F. Hoffmann-La Roche; ORATORIO ClinicalTrials.gov number, NCT01194570 .).

    In this study, we assessed the impact of multiple sclerosis (MS) on bodily self-consciousness (BSC) using the Rubber Hand Illusion. Patients with MS showed a dissociation between body ownership and self-location: they did report an explicit ownership of the rubber hand, but they did not point towards it, showing a defective ability of localizing body parts in space. This evidence indicates that MS may affect selective components of BSC, whose impairment may contribute to, and even worsen, the functional disability of MS. © 2017 The British Psychological Society.

    2013-09-15

    The diagnosis of multiple sclerosis is based on dissemination in time and space. Before 2010 lack of evidence for dissemination in space could be substituted by a paraclinical test, cerebrospinal fluid (CSF) oligoclonal bands (OCBs). The present meta-analysis (13,467 patients) shows that the diagnostic specificity of OCB drops from 94% to 61% if inflammatory etiologies are considered. Importantly, this was not caused by poor laboratory practice. This review on CSF OCB further illustrates the conceptional problem of substituting dissemination in space with a biomarker. The potential prognostic value of intrathecal OCB will need to be tested prospectively.

    2016-01-01

    Abstract Currently used classification schemes for multiple sclerosis (MS) have not taken into account disease severity, instead focusing on disease phenotype (ie, relapsing vs. progressive). In this article, we argue that disease severity adds a crucial dimension to the clinical picture and may help guide treatment decisions. We outline a practical, easy-to-implement, and comprehensive scheme for severity grading in MS put forward by our mentor, Professor Joseph Herbert. We believe that severity grading may help to better prognosticate individual disease course, formulate and test rational treatment algorithms, and enhance research efforts in MS. PMID:27803642

    Full Text Available ABSTRACT Multiple sclerosis (MS was always considered as a white matter inflammatory disease. Today, there is an important body of evidence that supports the hypothesis that gray matter involvement and the neurodegenerative mechanism are at least partially independent from inflammation. Gray matter atrophy develops faster than white matter atrophy, and predominates in the initial stages of the disease. The neurodegenerative mechanism creates permanent damage and correlates with physical and cognitive disability. In this review we describe the current available evidence regarding brain atrophy and its consequence in MS patients.

    Multiple sclerosis is characterized at the gross pathological level by the presence of widespread focal demyelinating lesions of the myelin-rich white matter. However, it is becoming clear that grey matter is not spared, even during the earliest phases of the disease. Furthermore, grey matter damage may have an important role both in physical and cognitive disability. Grey matter pathology involves both inflammatory and neurodegenerative mechanisms, but the relationship between the two is unclear. Histological, immunological and neuroimaging studies have provided new insight in this rapidly expanding field, and form the basis of the most recent hypotheses on the pathogenesis of grey matter damage.

    Multiple sclerosis (MS) is a chronic, autoimmune neurodegenerative disease. Epstein-Barr virus (EBV) infection is associated with MS pathogenesis. However, mechanism for the EBV-MS connection is unclear. The blood brain barrier (BBB) is a separation of circulating blood and the brain extracellular fluid in the central nervous system. BBB contains both endothelial cells as well as astrocytes. Interestingly EBV is able to infect both kinds of cells. Because EBV is able to transfer infection from one cell type to another cell type, it is thus hypothesized that EBV uses
