Active clinical trials for "Sclerosis"

This is an open label, non randomized, uncontrolled, multicenter, single arm observational study. In this study, the enrolled subjects will be treated with Rebif human serum albumin (HSA)-free formulation (with or without RebiSmart) 44 microgram (mcg), subcutaneous (sc), thrice in a week (tiw) for 24 months.

This is a case-control study performed on a biological collection. The polymorphisms present on a pre-defined list of genes will be studied for 400 Amyotrophic Lateral Sclerosis (sporadic type) DNA samples and 400 control DNA samples.

The primary objective of the study is to retrospectively investigate changes in lymphocyte counts and lymphocyte subtypes, with a focus on CD4+ and CD8+ T cells, in participants on Tecfidera therapy for at least 6 months. The secondary objective is to investigate changes in lymphocyte subtypes other than CD4+ and CD8+ T cells.

Systemic Sclerosis (SSc) is an inflammatory chronic disease that can lead to structural damage and handicap. The SSc physiopathology is multifactorial, including genetic and environmental risk factors. The identification of environmental factors implication is crucial to understand the SSc mechanism, and improves the diagnosis and the treatment of the disease.

Depression is one of the most common symptoms of multiple sclerosis (MS) with a life-time prevalence of major depressive disorder (MDD) of up to 50%. Depression occurs more frequently in MS than in other chronic diseases including other neurological and inflammatory disorders and may contribute to lower quality of life, cognitive problems, difficulties at work, and poorer long term health outcomes. Despite its clinical relevance, the biological mechanisms which may be responsible for the high risk for MS patients to develop depression are unknown. In this observational study, investigators explore the molecular mechanisms responsible for the impaired regulation of immune cells in relapsing-remitting (RR) MS patients with depression. Investigators will compare the molecular and phenotypical profile of immune cells obtained from RRMS patients with clinical depression (n=50), matched MS patients who do not suffer from depression (n=50) as well as matched healthy controls (n=50) and matched patients with depression but without a comorbid neurological disorder (n=50).

The primary objective is to evaluate changes in fatigue and physical activity (step counts) before and after rehabilitation in patients with MS (EDSS 3-6.5). The association of changes in fatigue and physical activity will also be analyzed for disease severity (EDSS), age, emotional status (depression) of the participants.

This pilot study will evaluate for the presence of neuromuscular junction (NMJ) defect in women with motor fatigue in multiple sclerosis by Single Fiber Electromyography (SFEMG) using the concentric needle electrode.

The purpose of this study is to assess whether skin biopsy specimens from patients with diffuse cutaneous systemic sclerosis (dcSSc) can be used as biomarkers (measures of activity and type) of disease to predict response to various experimental treatments. There are various experimental treatments being used in the treatment of slceroderma, but there is no way to predict response to any given therapy. The investigators will use DNA microarray to analyze the changes in gene expression in skin biopsies in response to various treatments. Our hypothesis is that the investigators will see changes in gene expression in response to various treatments that will give us insight into the cause of scleroderma. The investigators predict that they will be able to use this information to predict which experimental treatments will be beneficial to individual patients

This is a single-site, pilot study. In this study, we hope to learn if the Lido Workset is a sensitive measure of limb spasticity in patients with Multiple Sclerosis (MS). The Lido Workset is a FDA approved, non-invasive device which has been used to assess motor function and spasticity. The testing will take approximately 25 minutes. Subjects will lie down on a table and have a leg attached to the Lido Workset device arm. The Lido Workset will move the leg back and forth many times at different speeds. The Lido Workset will also analyze resistance to passive (while subject is not moving or resisting movement) movement of the wrist and knee.

The purpose of this study is to examine and compare changes in the specific thinking skills of patients with RRMS who are receiving treatment with one of three immunomodulatory medications (Avonex, Copaxone, or Rebif).
