Drugs for the Treatment of Multiple Sclerosis and Risk of Cancer: a Pharmacovigilance Analysis in...
Multiple SclerosisMalignant TumorEven 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.

Physiological Responses in Experimentally Induced Cognitive Fatigue in People With Multiple Sclerosis...
Multiple SclerosisFatigue1 moreThe current study will add to the current knowledge by combining several electrophysiological techniques to examine the relationship between physiological responses and cognitive fatigue and daily activity performance in a stress- and fatigue-inducing protocol. The aims of this study are: 1) to evaluate the feasibility and usability of assessing physiological responses in an experimental set-up and 2) to investigate the association between physiological outcomes, experimentally induced stress and cognitive fatigue in people with multiple sclerosis (MS) and healthy controls.

Telerehabilitation in Multiple Sclerosis
Multiple SclerosisPatients with multiple sclerosis will be randomized into two groups. One group will receive live telerehabilitation sessions 3 times a week over a course of three months. The other group will receive video instructions for aerobic and strengthening exercises. Patients fatigue, sleep quality and quality of life will be measured.

Pleiotropy and Mechanism of Peripheral Nerve Related Genes in the Progression of Amyotrophic Lateral...
Amyotrophic Lateral SclerosisThis study will establish a comprehensive exon database of ALS patients, lay the foundation for screening the genes related to the occurrence and development of the disease, support the theory of ALS disease progression from peripheral to central, and reveal the correlation between the functional level of peripheral nerve and the prognosis of the disease at the gene level for the first time, and provide the basis for the mechanism research at the molecular level.

Assesment of Physical Activity Level of Patients With Multiple Sclerosis: From Laboratory to Real...
Multiple SclerosisThis study aims to assess the feasibility of a protocol determining individual moderate-to-vigorous physical activity (MVPA) thresholds, among multiple sclerosis patients, in routine medical practice.

Study of the Role of G72 in Amyotrophic Lateral Sclerosis: Biomarker Discovery and Mechanism Investigation...
Amyotrophic Lateral SclerosisAlzheimer Disease1 moreG72 gene is located on the common linkage locus in bipolar disorder and schizophrenia, and it encodes D-amino acid oxidase activator (DAOA). There are evidences that elucidated G72 and D-amino acid oxidase(DAO) together playing a critical role in the pathophysiology of schizophrenia. Recently, reports discovered missense mutations in the DAO (R199W DAO and R38H DAO) are associated with familial amyotrophic lateral sclerosis (FALS), and our preliminary data showed that the level of G72 autoantibody decreases in patients with ALS compared with normal control. Thus, we want to find out whether G72 plays a role in ALS and neurodegenerative diseases including Alzheimer disease and Parkinson's disease. First, we detect G72 protein and its autoantibody in sera of neurodegenerative diseases patients using ELISA and Western blotting, and the data are compared with normal control. We hypothesize the levels of G72 protein and its autoantibody in neurodegenerative diseases are less than those in normal control. Then, we extract genomic DNA of neurodegenerative diseases patients, and use polymerase chain reaction(PCR) to detect single nucleotide polymorphism (SNP) of G72. We aim to detect G72 missense SNP variants presented in ALS, AD and PD.

The French Multiple Sclerosis Registry
Multiple SclerosisNeuromyelitis Optica Spectrum DisordersOFSEP 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.
