Filter by:The primary objective of this study is to characterize the antibody response to seasonal influenza vaccine, in patients with active RRMS, treated with cladribine, compared to control individuals with basic immunomodulatory treatment. Serum antibody titers against the respective pathogen will be assessed prior to and 6 to 8 months following vaccination.
Although the majority of the French population is covered by social security, the effects of social inequalities on health are still very visible and are even increasing in France and in Europe. Thus, according to INSEE, excess mortality is observed among the most disadvantaged populations. Similarly, the prevalence of certain chronic diseases in France and Europe, particularly cardiovascular diseases, is linked to social inequalities and excess morbidity can be observed in the most disadvantaged populations. In addition to social inequalities, which refer to disparities in health levels according to social category, there are the effects of territorial inequalities. In France, there are geographical areas of excess mortality, which essentially correspond to areas far from urban centers. Similarly, there are major geographical differences in terms of medical supply and equipment, and the distance between patients and health centers is a direct obstacle to the use of the health care network. The underlying explanations for social inequalities in health are multiple. While it is likely that difficulties in accessing and using care play a role, it is also possible that they are due to differences in exposure to certain environmental (e.g. pollution) or individual (e.g. smoking) risk factors. But it is also possible that the causal relationship is the opposite and that diseases create or reveal social inequalities. For multiple sclerosis (MS) the impact of social and territorial inequalities is more debated. Indeed, with regard to the relationship between disease prevalence and social inequalities, a recent literature review found 21 separate studies on the subject, of which 13 failed to show a link between socioeconomic status and MS risk, 5 concluded that there was an increased risk of MS in advantaged populations and 3 concluded that there was an increased risk of MS in disadvantaged populations. There are plausible pathophysiological explanations for either direction of the relationship, but the question remains open. To our knowledge, the link between MS prognosis and social inequalities has been little studied, as disadvantaged populations are more often exposed to the poor prognostic factor of smoking [6-8], the hypothesis of a negative prognostic role of social inequalities remains plausible. Similarly, the current consensus is that the diagnosis and treatment of MS should be as early as possible [9,10] in order to preserve brain capital. Easy access to a neurologist and MRI are therefore potentially prognostic factors for MS in relation to territorial inequalities. It should be noted that the link between social and geographical inequalities and a potential delay in treatment has not been demonstrated in France in the case of cancer, but it is possible that the importance of the means implemented in the fight against cancer erases these effects. In MS, a study showed a link between delay in starting a second disease-modifying therapy and socio-economic status. While the causal link between MS and socio-professional status has not yet been demonstrated, the socio-economic impact of MS has been measured. In particular, it has been shown that having MS is associated with an increased risk of unemployment and/or early retirement. The primary objective of our study is to determine whether delay in treatment, as a marker of difficulties in access to care in MS, is associated with social and territorial inequalities in MS. Secondary objectives will be to explore the link between MS prognosis and social and territorial inequalities. Exposure to sunlight is a known protective factor and is consistent with the north-east-south-west gradient observed in France. The choice of centers associated with the research, spread over the French territory, will make it possible to monitor and measure this effect in the prognosis of MS. As the available treatments have evolved considerably over the last ten years, and in order to avoid a period effect, the patients recruited in the study will have to have a date of onset of the disease after 1 January 2009.

This trial will study the safety and efficacy of intravenous infusion of cultured allogeneic adult umbilical cord derived mesenchymal stem cells for the treatment of Systemic Sclerosis
The purpose of this clinical trial is to determine if HCQ in a dose of 400mg daily and indapamide in a dose of 2.5mg daily can help in reducing the progression of disability in people with secondary progressive multiple sclerosis. The number of participants in this study will be 35. A maximum of 42 people with SPMS will be included. The trial is funded through internal funding through the University of Calgary. There is no sponsorship from any pharmaceutical industry.
Multiple sclerosis (MS) is a common inflammatory demyelinating disorder of the central nervous system frequently affecting females in their reproductive phase of life. In this prospective observational study, we obtain data on the outcome of pregnancies in MS patients and the influence of pregnancy on clinical, laboratory and MRI parameters in MS.
Multiple Sclerosis (MS) is a chronic inflammatory disease of the central nervous system (CNS) causing focal lesions of demyelination and diffuse neurodegeneration in the grey and white matter of the brain and spinal cord, leading to physical and cognitive disability. The scientific community and patients are in need for new and more reliable biomarkers, especially biomarkers of disease progression in order to adapt therapeutic approaches on an individual level. Digital biomarkers have the potential to fill this gap allowing for quasi-continuous measures that might be more informative than episodically collected conventional data concerning the impact of the disease on activities of daily living. Using app-based challenges, continuous monitoring and surveys the Investigators aim to obtain data that can be used as digital biomarkers (DB). These digital biomarkers will provide more granular and precise assessments, thus complementing traditional diagnostic measures and techniques. After a first feasibility study (ClinicalTrials.gov: NCT04413032) a number of digital biomarkers have been identified as reliable, reproducible and meaningful to PwMS and are therefore being validated in a bigger cohort of PwMS with a longer follow-up within this validation study 1. Those digital biomarkers will be compared to state-of-the-Art clinical, imaging and body fluid assessment.
The overarching goal of this project is to critically evaluate the efficacy of incorporating dietary guidance within multiple sclerosis (MS) care for improving long-term quality of life (QoL) compared to usual care. The primary objective of this study is to evaluate the effect of two dietary interventions (time restricted olive oil based (TROO) ketogenic and modified Paleolithic elimination) on MS QoL compared to usual care control (Dietary Guidelines for America), and the secondary objectives and the long-term effects on, motor function, low-contrast vision sensitivity, fatigue, mood, and disease activity assessed by brain imaging.
A complex interaction between demographic, environmental and genetic mechanisms impact the onset, severity and outcome of ILD-SARDs through dysregulation of the immune system and lung pro-biotic pathways. Comorbidity and genetic risk indicate that there are overlapping pathogenic mechanisms among SARDs, some of which underlie ILD in different SARDs. The purpose of this biobank is to study the clinical, pathological, laboratory, and imaging characteristics of SARDs patients with lung involvement. This will help identify as unique features underlying lung involvement in SARDs. In addition, this may lead to the discovery of novel mechanisms of disease and potentially novel targets of treatment for SARDs patients with lung disease.
This trial will study the safety and efficacy of intravenous infusion of cultured allogeneic adult umbilical cord derived mesenchymal stem cells for the treatment of multiple sclerosis
The 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.
