Filter by:Multiple sclerosis (MS) is the most common chronic inflammatory disease of the central nervous system1, whose demyelination is the pathological hallmark. MS is characterized by neuroinflammation, demyelination, axonal damage, and neurodegeneration2. The demyelination state in brain and the clinical course are difficult to predict in the early stage of disease. Recently, several neuroimaging and fluid biomarkers had been explored in MS. Using brain amyloid positron emission tomography (PET) in active MS had showed that both the damage sites and normal appearance white matter had a lower intensity than non-active MS. The result suggests a predictive role that the intensity from amyloid PET could reflect the disease activity and link to early myelin damage. The levels of tau protein in cerebrospinal fluid (CSF) had also been showed a negative correlation with brain atrophy, which is a prognostic marker for MS. In fluid biomarkers, both neurofilament light chain (NfL) and glial fibrillary acidic protein (GFAP) had been used in MS and reported correlations with disease severity, the extent of neuroinflammation and progression. In current study, investigator will enroll 38 participants with MS and evaluate their clinical severity; measure the WM lesion and disease activity by magnetic resonance imaging (MRI); myelination state and amyloid deposition by amyloid PET scan; tau deposition by state of-art tau PET scan. Investigator also measure the serum levels of NfL and GFAP as the index of axonal injury and disease activity. The relationship between disease severity, brain myelination, tau deposition and serum levels of NfL will be discuss.
Even though the therapeutic panel for multiple sclerosis (MS) treatment has improved in the last 20 years, safety data especially for the second-line and innovative treatments are lacking. The association between MS and cancer has long been investigated but has led to conflicting results. No studies have reported an increased risk of cancer after long-term exposure to immuno-modulators. The present study will assess whether drugs for the treatment of MS are associated with an increased risk of cancer by analyzing the disproportionality of reports in the World Health Organization (WHO) pharmacovigilance database.
Besides coping with the diagnosis, people with multiple sclerosis have to make complex decisions such as deciding about immunotherapies. They search not only for factual information, but also for reports of patient experiences (PEx). The investigators aim to evaluate in a randomised controlled pilot trial whether a website presenting PEx as an adjunct to factual information may help people with multiple sclerosis in their immunotherapy decision-making processes.
Using magnetic resonance-PET (MR-PET) imaging with [11C]PBR28, a second-generation 18kDa translocator protein (TSPO) radiotracer, we have previously demonstrated abnormally high TSPO expression, indicative of microglia activation, across different brain tissue compartments of multiple sclerosis (MS) patients1. In this study, we propose to study the efficacy of ocrelizumab, a humanized monoclonal antibody that has been shown to decrease neuroinflammation in relapsing-remitting multiple sclerosis (RRMS) and progressive multiple sclerosis (MS) patients. We will test these effects by studying a cohort of 24 MS patients (12 RRMS, 12 progressive MS). Participants will be studied before (within 3 months prior to initiating treatment) and after treatment with ocrelizumab (~12 month follow up), a therapeutic drug that will be part of their standard medical care. We will use [11C]PBR28 to help determine changes in neuroinflammation. The purpose of this study is to determine the effects of ocrelizumab treatment on neuroinflammation by analyzing the uptake and distribution of [11C]PBR28 in individuals with multiple sclerosis. The specific aims of the current study are: 1. To assess whether treatment with ocrelizumab in subjects with either relapsing-remitting MS or progressive MS is associated with decreased [11C]PBR28 binding in the cortex and white matter (lesions and normal appearing white matter), suggesting reduced neuroinflammation. 2. To assess whether changes in neuroinflammation under ocrelizumab treatment, as measured by [11C]PBR28 uptake at 12-month follow up relative to baseline, are associated with changes in structural MR metrics of brain tissue damage including white matter lesion load, cortical atrophy, and demyelination in the cortex and in the normal-appearing white matter as measured by magnetization transfer ratio (MTR). 3. To explore whether changes in functional and structural imaging metrics under ocrelizumab are associated with changes in clinical outcome measures.
The purpose of the clinical trial is to test how Simvastatin (80mg/day) may decrease attacks and progression of disease in patients with multiple sclerosis under disease modifying therapy (DMTs)
New research in animal models of MS suggests that greater training intensity is required to restore lost functions. We have developed and tested vigorous intensity cool room treadmill training that people with MS who have fatigue and heat-sensitivity can tolerate. This study will focus on the appropriate dosage of training.
This is a placebo-controlled, double-blinded, randomized trial design, whereby all patients are eligible to start an injectable therapy, and then randomized to either placebo or FMT for approximately 1 year.
Multiple sclerosis (MS), a chronic inflammatory disease of the central nervous system, is characterized by myelin, oligodendrocytes and axon damage. Physical exercises can be beneficial to patients, reduce fatigue and improve their strength, endurance and quality of life. Exercise has the potential to improve and / or preserve functionality, aerobic condition, strength, fatigue, health-related quality of life, depression, and cognition in MS patients. It has been reported that aerobic exercise increases muscle strength and endurance in peak oxygen intake and decreases fatigue and improves activity level, balance and walking patterns. It is important to control the problems caused by ataxia in MS patients, to improve balance and postural reactions and to increase proximal muscle and trunk stabilization. For this purpose, movements are voluntarily and graded. Progress in exercises is achieved by making changes in the speed, width and complexity of movement. However, Frenkel Coordination exercises for extremity ataxia are usually included in the physiotherapy and rehabilitation program. Little is known about the role and function of the iris in the nervous system with the discovery of Irisin and its precursor protein FNDC5. Evidence that the plasma level of iris increases during physical exercise suggests that it may also have beneficial and neuroprotective effects in the brain. Increased physical exercise has been shown to be associated with FNDC5 expression and ultimately more secretion of the iris. The effect of elevated plasma iris levels after aerobic exercise on functionality in MS patients is unknown. Moon et al. Observed that cellular proliferation in mouse hippocampus cells was dose-dependent due to iris. In spraque dawley-type male rats, the presence of significant iris in the myelin sheath of the skeletal muscle shows that this tissue is an important source of iris. Based on these findings, it is thought that exercise-induced iris, which is an important cause of disability in MS, may have beneficial effects on the recovery of normal function in these patients. Whether iris affects nerve conduction velocity will be determined by electromyography analysis before and after aerobic exercise. In addition, the relationship between aerobic exercise and motor and sensory function and iris will be investigated and evaluated with functional tests.
The patient's reporting of adverse drug reactions (ADRs) is recognized as being of interest for post-marketing safety monitoring, but is still underdeveloped in France, with an average lower than the European average. A multidisciplinary team of the University Hospital of Caen, composed of neurologists and pharmacovigilants, has been carrying out since autumn 2017 a national study (VIGIP-SEP1) with 24 research centers in France (12 universitary hospitals, 6 general hospitals, and 6 private-practice neurologists) whose main objective was to evaluate the impact of multiple sclerosis (MS) patients' use of a mobile application (App) to report their ADRs. My eReport France® has been developed by the eVedrug company: ADR reports are sent by patients directly to the Regional Pharmacovigilance Centers, after analyze, clinical pharmacologist send it to the National Competent Authority. As part of VIGIP-SEP1, the accompaniment for the use of the App was carried out very simply by neurologists. We designed a randomized controlled trial based on the assumption that a nurse training of the patient, after the initial prescription of an oral MS drug, with a telephone follow-up within 6 months, will increase by 3 times the number of patients who report ADRs compared to a simple information presented by the neurologist. The number of subjects required is 23 subjects per group.
patient with multiple sclerosis will undergo and completed comprehensive survey measuring body mass index and assessment of obesity ,health related quality of life,disability,relapsing and complete data on their dietary habits.
