Filter by:Aims of this study are to observe the correlation between ABCB1、VDR、TBX21、NR3C1 and other gene polymorphisms and the effect of glucocorticoid shock therapy on neuromyelitis optica. Investigators plan to include patients with neuromyelitis optica who will receive glucocorticoid shock therapy prospectively. The patients are divided into glucocorticoid sensitive (GS) group and glucocorticoid resistance (GR) group according to the change of central vision after treatment. Patients' clinical data will be collected and blood samples are needed for single nucleotide polymorphism (SNP) typing test. Through statistical analysis, the data differences between GS group and GR group were compared, and the effects of clinical indexes and gene polymorphisms on the efficacy of glucocorticoid shock therapy in the treatment of neuromyelitis optica should be analyzed.
Antibody-mediated inflammatory diseases of the nervous system (also known as autoimmune diseases of the nervous system) are autoimmune diseases in which autoimmune cells and immune molecules attack the nervous system as the main pathogenic mechanism. In the immune response, pathogenic antibodies acting on autoantigens of the nervous system are collectively referred to as autoantibodies of the nervous system, and antibody-mediated inflammatory diseases of the nervous system can occur in the central nervous system, peripheral nervous system, and neuromuscular junctions, and muscles. In this study, we will recruit eight kinds of autoimmune diseases of nervous system including Neuromyelitis Optica Spectrum Disorder (NMOSD), Myasthenia Gravis (MG), Chronic Inflammatory Demyelinating Polyradiculoneuropathy (CIDP), idiopathic inflammatory myopathyand (IIM), multiple sclerosis (MS), autoimmune encephalitis (AE), Myelin Oligodendrocyte Glycoprotein Antibody-Associated Disease (MOGAD) and POEMS Syndrome. B-cell maturation antigen (BCMA) is expressed on the surface of plasma cells, thus making it an ideal target for targeted therapies. Chimeric antigen receptor (CAR) T cells against BCMA offers another potential therapeutic option to eliminate plasma cells in patients with neurological autoimmune diseases driven by abnormal antibody who still suffer recurrent attacks from conventional treatments. In the current study, the safety and efficacy of a novel CAR-T cell therapy using CT103A cells, are evaluated in patients with relapsed/refractory antibody-mediated idiopathic inflammatory diseases.
This study is a phase I clinical study of the safety, tolerability, and pharmacokinetics of BAT4406F injection in patients with neuromyelitis optica spectrum disorders.
CLUE is a prospective study to determine structural and functional changes of brain and spinal cord, as well as the inflammatory environment in patients with neuroinflammatory and demyelination disease. Subjects will receive new magnetic resonance (MR) technics including double inversion recovery (DIR) imaging diffusion kurtosis imaging (DKI), quantitative susceptibility mapping (QSM) and resting-state functional imaging and follow up for one year.
The influence of pregnancy on the course of multiple sclerosis (MS) has long been a controversial topic. After the publication of the first large prospective study of pregnancy and MS in 1998, counselling of women with MS has radically changed and many patients have been able to fulfill their desire of motherhood. However, there are still some challenges for the neurologist, who has to face old unanswered questions or new issues, regarding the use of disease modifying drugs (DMDs) in this period of life, effects on the short and long term outcome of the mother (in terms of relapses and disability) and the child, role of breast-feeding and locoregional analgesia. To set up a national prospective pregnancy registry for patients with MS, nested within the Observatoire Français de la Sclérose en Plaque (OFSEP) cohort, owing to a better knowledge of interactions between MS and pregnancy-related issues (pregnancy itself, locoregional analgesia, breastfeeding, impact of using or stopping DMDs on women/children…)
Background: Optic neuritis is a frequent cause of vision loss encountered by ophthalmologists in the Caribbean. The diagnosis is made on clinical grounds. Optic neuritis can occur either in an isolated manner or, most often, as the first symptom of multiple sclerosis (MS) or neuromyelitisoptica (NMO). These 2 demyelinating disorders differ by many means, including treatment and prognosis. MS can cause severe long-term disability while NMO is a short-term sight- and life-threatening condition causing potential relapses, which may require plasma exchanges. Furthermore, disease-modifying therapies used in NMO are different from those used in MS, which can worsen the natural history of NMO. Early differential diagnosis of these diseases is thus crucial for preventing severe visual loss and disability.
The purpose of this study is to initially observe the safety and effectivity of RC18 in Participants with Neuromyelitis Optica Spectrum Disorders.
OFSEP is an observational cohort of Multiple Sclerosis (MS) and related disorders set up in France. It aims to provide a major epidemiological tool on MS for the scientific community in France and abroad. This tool must help to answer a large number of questions concerning the causes and mechanisms of MS, the prognostic factors of disease progression, the effectiveness and safety of therapeutic drugs, the impact of the disease on patients and society, etc. In December 2015, it has already included more than 54.000 patients. To achieve this goal, OFSEP's objectives are - To maintain and develop the French cohort of patients suffering from MS or related diseases and syndromes. This means collecting standardized socio-demographic and clinical data as part of the routine medical follow-up of patients already in the cohort and recruitment of new patients. - To supplement the existing clinical data with standardized and quality biological samples and MRI scans. - To improve the previous data with medical/administrative data from the health insurance fund databases in particular, in order to get more information on comorbidity, treatment protocols and the medico-economic aspects of this disease. - To use OFSEP infrastructures to facilitate the implementation of specific studies requiring the collection of additional data or specific patient monitoring processes. - To ensure the availability of these data and samples to researchers, health care authorities and industrial players to enable analysis and thus provide answers to research questions or public health issues. This availability is only possible after scientific and regulatory evaluation of the request. - To provide regular descriptions of the patient population in the cohort to offer statistics, targets and up-to-date information on this disease and thus enable a better approach to the personal, professional and social impacts of the illness, the effects of basic treatments and the requirements related to the follow-up of this disease in France. - To conduct specific studies on the entire population of patients in the cohort (parent cohort) or on patient sub-groups with specific characteristics (nested cohorts). Four nested cohorts have been defined: patients with radiologically isolated syndromes, patients with clinically isolated syndromes, patients with primary progressive courses of the disease and patients with neuromyelitis optica (Devic's syndrome) spectrum disorders.
To investigate multimodel MRI exploring the pathophysiology of multiple sclerosis and neuromyelitis optica spectrum disorders. The investigators use multimodel MRI to evaluate the extent of blood-brain barrier and white matter fiber tracts destruction , iron deposition and cerebral blood flow of associated regions in multiple sclerosis and neuromyelitis optica spectrum disorders using contrast-enhanced magnetic resonance imaging , quantitative susceptibility mapping, diffusion tension imaging, and arterial spin labeling with post labeling delay of 2.0 seconds. Transfer constant volume , magnetic susceptibility, cerebral blood flow and fractional anisotropy(FA) value were measured in lesion and normal appearing white matter.
The treatment protocol consisted of 12 mg/m2 MITO intravenous infusions every 3 months for 2 years. Dosage was adjusted according to side effects. Neurological assessment including the determination of the Expanded Disability Status Scale (EDSS) score and ophthalmologic evaluations were performed every 3 months and during relapses. Flow cytometric analysis, brain and spinal cord MRI was performed at baseline, 6, 12, 18, and 24 months.
