Active clinical trials for "Neuromyelitis Optica"

In 1894, Devic first proposed the concept of neuromyelitis optica(NMO). NMO is an inflammatory demyelinating disease that selectively affects the central nervous system of the optic nerve and spinal cord.In 2004, Lennon and other persons found highly specific AQP4（aquaporin 4）antibodies in NMO patients'sera, and further differentiated between NMO and MS, confirming that NMO is an independent disease.At present, NMO has been widely recognized as an idiopathic and severe demyelinating disease of the central nervous system.In 2015, the international NMO diagnostic team developed the diagnostic criteria based on highly specific AQP4 antibodie.Up to now, in China, there is no data on the number of NMOSD patients, the rate of misdiagnosis, the treatment methods, and the prognosis.This study is committed to build China's NMOSD big data platform to provide the basis for diagnosis, treatment and prognosis of the disease.

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.

Neuromyelitis Optica (NMO)/ Neuromyelitis Optica Spectrum Disorders (NMOSD) is an immune-mediated inflammatory demyelinating disease of the central nervous system mainly involving optic nerve and spinal cord. It is clinically characterized by simultaneous or sequential involvement of the optic nerve and spinal cord, presenting a progressive or remission and relapse course, which can lead to paralysis and blindness. The objective of this study is to provide evidence regarding treat effects and factors related to prognosis which will help physicians better evaluable risk-benefit in NMOSD management and improve patients' outcome.

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.

Multiple sclerosis (MS) is the most common demyelinating disease of the central nervous system and the most common cause of non traumatic disability in young and middle-aged people. Neuromyelitis optica spectrum disease (nmosd) is an independent disease different from Ms. the pathogenesis and the mode of brain and spinal cord injury are different from MS, and the prognosis and optimal treatment are different. It is difficult to distinguish the two diseases in the early stage. Early diagnosis and treatment of the two diseases can greatly improve the quality of life of patients. Therefore, it is an urgent problem to clarify the difference between MS and nmosd injury patterns and to find sensitive imaging markers for early clinical intervention. With the continuous progress of computer aided diagnosis (CAD), it is more and more widely used in medicine, which is expected to help solve the above problems. The purpose of this study is to create a neuroimmune disease evaluation database based on image data. By combining brain and spinal cord imaging, and based on Zhang quantum space learning computer-aided technology, we can achieve accurate segmentation of MS and nmosd brain and spinal cord lesions, analyze the evolution characteristics of the disease at different time points, and screen the imaging indexes related to clinical scores combined with clinical and laboratory indexes Objective: to determine the different prognosis and its influencing factors at the clinical, imaging and molecular levels, and establish the model for predicting disease progression and prognosis, so as to provide the basis for early identification and assistance in guiding treatment and judging prognosis. Clinical information was collected: age, gender, course of disease, MMSE, EDSS disability score, nine hole test, 25 foot walking test. Assess the patient's information processing ability. Blood samples were collected. Imaging examination was performed. The patients were followed up regularly.

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 purpose of this study is to collect French medical data for patients with Multiple Sclerosis (MS) or NeuroMyelitis Optica (NMO) spectrum disorder who are diagnosed or strongly suspected of being infected with Covid19. The objective of this study is to provide scientific information regarding the possible risk factors in these patients, as a large part of them receive immunomodulatory or immunosuppressive treatments. The main objective of this study is thus to determine the epidemiological (eg, age, form of disease, disability) and pharmacological (related to immunomodulatory or immunosuppressive treatments) factors favoring the occurrence of a severe form of Covid-19 in MS and NMO patients.

The purpose of this study is to determine the ability of STRATUS OCT and high resolution OCT to detect and to quantify the neural loss in multiple sclerosis and neuromyelitis optica and its subtypes.
