Filter by:Multiple sclerosis (MS) is the first non-traumatic cause of disability in young people, responsible for physical but also cognitive deficits. MS is an inflammatory demyelinating and degenerative disease of the central nervous system. Recently, MRI technics have demonstrated their sensibility to the different processes involved in MS. Particularly, MRI has evidenced that the pathological process of MS is not restricted to the macroscopic lesions of the white matter but also involves the normal appearing white and grey matter. In the normal appearing brain tissue, demyelination, neuronal suffering and neuronal loss have been evidenced. Moreover, MRI has demonstrated the existence of brain functional reorganization processes that may limit the clinical expression of pathological injuries. Despite these important findings, the pathological underpinnings of irreversible disability are largely unknown. The present project aims to depict the main determinants of physical but also cognitive disability in patients with MS. To do this, a longitudinal study including 70 patients with MS using different MRI markers known to be sensitive to the different pathological aspects of MS will be performed. The relationships between these markers and the progression of disability will be assessed. Identification of the main pathological underpinnings of irreversible disability of MS will provide the most relevant therapeutic targets.
Systemic sclerosis is a rare pathology characterized by fibrosis and vascular lesion with skin, pulmonary, digestive and cardiac localisation. Calcinosis cutis is commonly described, but its prevalence and appear few documented in literature. Moreover, this studies used clinical observation to determine presence or absence of calcification, and rarely radiography, in particular for feet localisation. In the same way, skin calcification and organ injury association appear unclear. The aim of the study is firstly to determine prevalence of calcinosis cutis, with hand and feet radiography realisation in a cohort of systemic sclerosis patient. Secondly, will be determine the correlation between calcinosis and organ injury.
The purpose of this study is to evaluate the safety, tolerability, and feasibility of Blood-Brain Barrier (BBB) opening using transcranial MRI-guided focused ultrasound in conjunction with an intravenous ultrasound contrast agent in patients with Amyotrophic Lateral Sclerosis (ALS).
To develop a test to characterize and monitor Multiple Sclerosis (MS) disease status and therapy response from a participant's home by analyzing the gene expression from participant self-collected blood samples using a novel fingerstick collection kit.
The alteration of iron metabolism is reported in animal models of amyotrophic lateral sclerosis (ALS) as well as in sporadic and genetic forms (SOD1 and C9orf72) of ALS. The high iron concentration of the brain, due to its high energy demand (high oxygen consumption), makes motor neurons particularly vulnerable to energy deficit and oxidative stress. Post-mortem examinations and MRI scans in patients with ALS have found signs of iron accumulation in the central motor tract; and a high level of serum ferritin, which is a marker of iron levels, is associated with a lower prognosis. In ALS mouse models, the use of iron chelators has demonstrated neuroprotection and increased life expectancy, suggesting that elimination of excess iron from the brain can prevent neuronal loss and, consequently, a slow progression of the disease. Conservative chelation of iron refers to a modality whereby much of the iron that binds to the chelator is redistributed in the body rather than exhausted. Using a chelator, deferiprone, with this feature, in a safety pilot study, a very good safety profile was observed. Deferiprone eliminated excess iron from brain regions, reduced oxidative damage and cell death associated with regional iron deposits with no apparent negative impact on the iron levels needed. Now, the efficacy of this new therapeutic modality of neuroprotection is being evaluated in a randomized, double-blind, placebo-controlled, multicenter study.
Amyotrophic Lateral Sclerosis (ALS) is a neurodegenerative disease that causes the death of 30,000 affected individual every year. Complex nature and unknown pathogenesis of this disease are 2 major reasons for failure of therapeutic interventions. Edaravone is a free radical scavenger that slows down functional decline and prevents from disease progression in ALS patients. FDA newly approved this drug in these patients (2017/5/5). In this study, investigators aimed to assess the treatment effect of this newly approved drug in patients with ALS in a representative Iranian population.
The purpose of this study is to determine the safety and efficacy of intrathecal treatment delivered to the cerebrospinal fluid (CSF) of mesenchymal stem cells in ALS patients every 3 months for a total of 4 injections over 12 months. Mesenchymal stem cells (MSCs) are a type of stem cell that can be grown into a number of different kinds of cells. In this study, MSCs will be taken from the subject's body fat and grown. CSF is the fluid surrounding the spine. The use of mesenchymal stem cells is considered investigational, which means it has not been approved by the Food and Drug Administration (FDA) for routine clinical use. However, the FDA has allowed the use of mesenchymal stem cells in this research study.
This is an open-label pilot study to determine the safety and tolerability of infusions of autologous CD4+ CD25+ regulatory T cells with concomitant subcutaneous IL-2 injections in 4 subjects with ALS.
The purpose of this study is to evaluate the safety and efficacy of HLA-haplo matched Allogenic Bone Marrow Derived stem cells("HYNRCS-Allo-ALS-02 inj"), through intrathecal delivery for the repeated treatment after 6 months of first treatment in patients with amyotrophic lateral sclerosis(ALS). This study is an open label, single-dose study to assess the safety and efficacy of HLA-haplo matched Allogenic Bone Marrow Derived stem cells("HYNRCS-Allo-ALS-02 inj")
The effects of multiple sclerosis (MS) on cognition, thought to occur in 50-75% of persons with MS, have gained increasing recognition as one of the major disabling symptoms of the disease. While numerous studies have addressed the emotional and physical impact of MS, little attention has been given to strategies that might help manage the cognitive changes commonly experienced by persons with MS. The proposed study will test a novel computer-assisted cognitive rehabilitation intervention, MAPSS-MS (Memory, Attention, & Problem Solving Skills for Persons with MS). The MAPSS-MS integrates the powerful effects of group interventions to build self-efficacy for new cognitive compensatory strategies/behaviors with individual home-based computer-assisted training. The computer training will assist individuals to develop cognitive skills that they can apply to everyday life using the compensatory strategies learned in the class sessions. In the recently completed exploratory study with 61 persons with MS (R21NR011076), the eight-week MAPSS-MS intervention was acceptable and feasible and had medium to large effects on the use of compensatory strategies and performance on neuropsychological tests of verbal memory. The proposed study will test the refined MAPSS-MS intervention with a larger more diverse sample (N=180) across multiple sites, extend the period of post-intervention follow-up to 6 months and establish whether performance improvements on neuropsychological tests make the important transfer to improved neuro-cognitive functioning in everyday life. The specific aims of this study are to: (1) Evaluate the efficacy of the novel MAPSS-MS cognitive rehabilitation intervention to improve overall neuro-cognitive competence in activities of daily living including verbal memory performance, use of compensatory cognitive strategies and performance on cognitive-related instrumental activities of daily living (IADL) among persons with MS; (2) Evaluate the efficacy of the MAPSS-MS intervention to improve self-efficacy and related aspects of cognitive performance (non-verbal learning/memory, information processing speed and attention, verbal fluency and complex scanning and tracking) among persons with MS; and (3) Determine the number of intervention participants who achieve and maintain their self-identified cognitive goals three and six months following the intervention. The effects of the intervention on outcome variables will be assessed using a randomized controlled trial design with a comparison group receiving usual care computer games. Measurements of study variables will occur at baseline, immediately after the MAPSS-MS intervention, and three months and six months after the intervention is complete. Statistical analysis will include descriptive statistics and HLM analysis to account for the nested design. The intent-to-treat approach will be used. Public Health Statement: This research will provide new knowledge about an innovative intervention to improve memory, use of compensatory strategies, and performance of cognitive activities and instrumental activities of daily living for persons with MS. If effective, the intervention would provide a new and feasible approach to target a serious, debilitating problem commonly experienced by persons with MS.
