PET Study in Multiple Sclerosis

Multiple Sclerosis

While both conventional and advanced MRI techniques offer important insights into MS pathophysiology, important aspects of this inflammatory disorder are undetectable with existing MRI technology. In Multiple Sclerosis (MS), there is growing interest in PET as an imaging modality that can increase the investigator's understanding of the disease processes and may add to an understanding of MS phenotype, particularly when combined with advanced MRI techniques such as myelin water imaging.

Phenotypic and Functional Study of 4BL B Cells in Multiple Sclerosis (MS)

Multiple Sclerosis

Recent works highlight the B cells involvement in multiple sclerosis (MS) pathology but their role remains poorly understood. It was previously described that activated memory B cells called 4BL due to the increased expression of 4-1BBL, an activation marker, induce pro-inflammatory response by activating T CD8+ lymphocytes. Those 4BL cells are also described in systemic inflammation in 80 years old people explaining the poor efficiency of vaccination in that sub population. Those 4BL cells can also induce anti-tumoral T cell response. The hypothesize is that 4BL may induce a pathogenic inflammatory response in MS.

COVID-19 Related Lockdown Effects On Chronic Diseases

Chronic Coronary SyndromeHeart Failure6 more

The containment associated with the VIDOC-19 pandemic creates an unprecedented societal situation of physical and social isolation. Our hypothesis is that in patients with chronic diseases, confinement leads to changes in health behaviours, adherence to pharmacological treatment, lifestyle rules and increased psychosocial stress with an increased risk of deterioration in their health status in the short, medium and long term. Some messages about the additional risk/danger associated with taking certain drugs in the event of COVID disease have been widely disseminated in the media since March 17, 2020, the date on which containment began in France. This is the case, for example, for corticosteroids, non-steroidal anti-inflammatory drugs but also for converting enzyme inhibitors (ACE inhibitors) and angiotensin II receptor antagonists (ARBs2). These four major classes of drugs are widely prescribed in patients with chronic diseases, diseases specifically selected in our study (corticosteroids: haematological malignancies, multiple sclerosis, Horton's disease; ACE inhibitors/ARAs2: heart failure, chronic coronary artery disease). Aspirin used at low doses as an anti-platelet agent in coronary patients as a secondary prophylaxis after a myocardial infarction can be stopped by some patients who consider aspirin to be a non-steroidal anti-inflammatory drug. Discontinuation of this antiplatelet agent, which must be taken for life after an infarction, exposes the patient to a major risk of a new cardiovascular event. The current difficulty of access to care due to travel restrictions (a theoretical limit in the context of French confinement but a priori very real), the impossibility of consulting overloaded doctors, or the cancellation of medical appointments, medical and surgical procedures due to the reorganization of our hospital and private health system to better manage COVID-19 patients also increases the risk of worsening the health status of chronic patients who by definition require regular medical monitoring. Eight Burgundian cohorts of patients with chronic diseases (chronic coronary artery disease, heart failure, multiple sclerosis, Horton's disease, AMD, haemopathic malignancy, chronic respiratory failure (idiopathic fibrosis, PAH) haemophilia cohort) will study the health impact of the containment related to the COVID-19 pandemic.

Validation of the French Adaptation of the MSWDQ-23 Questionnaire

Multiple Sclerosis

MS is an autoimmune disease of the central nervous system that affects more than 120,000 people in France. The average age of onset of the disease is between 25 and 35 years. Given the wide range of ages of the patients, from 4 to 80 years, the ethical and socio-economic stakes are high in order to maintain their autonomy, sociability, family and intimate life, and their employment in the best possible conditions and for as long as possible. However, to date, there are no evaluation tools in French that allow us to understand the difficulties at work of MS patients. The Multiple Sclerosis Work Difficulties Questionnaire (MSWDQ-23) was developed specifically for MS patients and validated in English [1]. There is a short version of this questionnaire that facilitates its use in clinical practice [2]. It has been translated and validated in Spanish through a multicenter study, and is currently being validated in German, but does not currently exist in French [3]. The main objective of the WORKSEP project is to validate the French version of this questionnaire through a multicenter population-based cohort within the framework of the French-speaking Multiple Sclerosis Society (SFSEP). This validation study will involve the inclusion of 206 French-speaking MS patients, regardless of their professional status, all forms of MS combined, from the early stage (Clinically Isolated Syndrome) to the more advanced stages (primary and secondary progressive forms).

Evaluation of the Incidence of Relapses in Patients With Biotin-treated Progressive Multiple Sclerosis...

Progressive Multiple Sclerosis

Background: High dose biotin is a therapeutic option for French progressive Multiple Sclerosis (MS) patients, without relapse for at least one year, since June 1, 2016. Despite the inflammatory activity of progressive forms of MS is known to be low, several publications mentioned clinical and/or radiological activity for biotin-treated patients. Objectives: To determine if high dose biotin increase the clinical inflammatory activity of patients with a progressive form of MS. To compare the clinical characteristics of the relapses that occurred with biotin or not. To describe the characteristics of the patients with a clinical inflammatory activity with biotin. Methods: This is a national, academic, observational and retrospective study comparing one group of progressive MS patients with high dose biotin to another group without this treatment using a propensity score, in intention to treat. The main judgment criterion is the annualized relapse rate (ARR) from the beginning of the biotin to the last evaluation available before the data extraction. A Student's t test will be used. A negative binomial modelling with relapses counting over a period of exposure and taking into account the inter and intra center variability will be used. The statistical tests will be adapted to the nature of the variables concerning the secondary judgment criteria. Expected results: This French national study will provide a better knowledge of the inflammatory activity of the progressive forms of MS treated with high dose biotin. If an increased clinical inflammatory activity is highlighted with biotin a prospective study will be necessary to confirm the result before a specific information of the scientific community and the patients about this risk or even an amendment of prescription rules in order to secure the use of the product. On the contrary, the absence of increased risk of clinical inflammatory activity with biotin would help to reassure the prescriber and the patient about the innocuity of the treatment.

Characterization of White Blood Cells Sub-populations From Multiple Sclerosis Patients.

Multiple Sclerosis

Multiple sclerosis (MS) is a chronic progressive neurological autoimmune disease, that gradually affects patient's quality of life. There are about 2.5 millions patients world wide, with an increasing cost Burdon. Up to date, it remains unclear who are the exact cells to initiate the disease. During the disease, the repertoire of cells expands and undergoes changes. The purpose of this study is to characterize those changes.

Investigation of GM Pathology Using Ultra High Field (7T) MRI Scanner

Multiple Sclerosis

Magnetization transfer imaging is a magnetic resonance technique that has been used over the last few years, and known for its ability to detect abnormalities that can be difficult to detect by conventional MRI techniques. The investigators would like to test if using an 7 Tesla MRI research scanner can help us diagnose Multiple Sclerosis more efficiently compared to the current clinical practice, i.e. if Multiple Sclerosis lesions in Gray Matter can be more readily identified and associated with disease stage on Magnetic Transfer MRI images as opposed to conventional procedures. Image analysis will allow the investigators to perform lesion segmentation and sequence comparison between different MRI techniques. The investigators will apply computation techniques to measure the local cortical thickness. Repeated scans at 6 monthly intervals over two years will give an insight into the changes in cortical thickness over time. Based on obtained data the investigators will look for the relationship between lesion loads in White Matter and Gray Matter, cortical thickness and disease stage.
