Active clinical trials for "Sclerosis"

Multiple sclerosis (MS) is a chronic inflammatory demyelinating disease of the central nervous system (CNS) and is one of the most common neurological diseases, often leading to disability of the patients. The MS pathogenesis includes vascular and inflammatory components, however recently also the role of mitochondrial dysfunction being a hot topic in neurodegeneration.

Twenty subjects (10 patients and 10 age-matched control volunteers) will be recruited for this study. MRI scans will take place on a 3T MRI Scanner (Skyra or Prisma, Siemens Medical Solutions) located at The NYU Center for Biomedical Imaging. MRI scans will consist of a 1-hour brain scan for both patients and controls. In the first 6 months of the study, investigators will develop and test a uMT-based APT imaging for brain tissue pH measurement and use a hypercapnia paradigm to validate the tissue pH changes between breathing room air and 5% CO2 (by increasing tissue acidity) inhalation. With implementation of hypercapnia MRI, pH-weighted imaging will be validated for its robustness and reproducibility.

This is a pilot study looking at the feasibility of a mobile application (app) to collect data from active tasks (questionnaires, 6Mapp™, COGapp™, VISapp™), clinical magnetic resonance imaging information and conduct genome-wide association studies in subjects with multiple sclerosis. Participants will be self-referred to this study from different sources; patient advocacy groups, social media tools, clinicaltrials.gov, and flyers.

Beyond white matter pathology, grey matter damage is considered as a key player in disability onset and progression in Multiple Sclerosis (MS). The underlying substratum of grey matter damage is complex and pluriform, ranging from cortical demyelinating lesions, synapse and dendrite disappearance to neuronal cell death. Current Magnetic Resonance Imaging MRI techniques fail to fully assess and quantify grey matter pathology in this disease. The development of a quantitative marker of neurodegeneration for MS patients would allow: (i) to better understand the pathophysiological mechanisms underlying the distinct forms of MS; (ii) to stratify patients according to their prognosis; and (iii) to evaluate new therapies aimed at promoting neuroprotection. would allow to better understand the mechanisms underlying the distinct forms of MS, to stratify patients according to their prognosis, and to evaluate new therapies aimed at promoting neuroprotection.

The primary objective is to assess the burden of aesthetic complication in systemic sclerosis. Systemic sclerosis is associated with changes in skin aspect which can impact the appearance. Aesthetic burden will be assessed through several scales and compared to a control group of health subjects.

Using an automatic software tool, Pixyl.Neuro, to conduct a retrospective analysis (detection of lesions + segmentation of images + tracking over time) of cerebral MRI images acquired during a prospective study of patients presenting with clinically isolated syndrome, and comparing the results against manual analysis.

Background: Pre-eclampsia, defined by the association of an arterial hypertension and significant proteinuria after 20 weeks of gestation, complicates 1 to 2% of pregnancies in France. Its pathophysiology involves angiogenesis impairment, upregulated maternal systemic inflammatory response, activation of oxidative stress and endothelial dysfunction. In a recent Danish nation-wide cohort study, pre-eclampsia was associated with a 69% increased risk of later developing scleroderma. Type of study: prospective observational case-control study. Primary objective of the study: to determine if a history of pre-eclampsia before systemic sclerosis diagnosis is an independent risk factor for vascular phenotype in sclerodermic women. Secondary objective: to describe all risk factors for vascular phenotype in sclerodermic women with a previous pregnancy longer than 6 months before scleroderma diagnosis.

Venous thrombo-embolic (VTE) rates could be high in patients with amyotrophic lateral sclerosis (ALS). Indeed, the rate of VTE in this specific population could be 7-fold higher in this population. Predictiv factors of VTE in patients with ALS are mobility reduction and neurological paralysis. However, to our knowledge, medical littérature is poor concerning VTE and ALS association. Our first aim is to define annual rate of VTE in ALS population.Then we aim to identify predictiv factors of VTE in this specific population. The studied population is Brest universitary hospital cohort of ALS patient included between 2000 and 2019.

This Individual Patient Expanded Access IND has been created as requested by an 83-year-old man who suffers Primary Lateral Sclerosis and for which the drugs currently approved are not providing an improvement over the progression of this disease.

Balance and gait disturbances are among the most common problems in patients with Multiple Sclerosis (MS). There is evidence of decreased foot sole sensation in MS patients. Studies conducted in healthy individuals have revealed the relationship between balance and foot sole sensation. These studies have demonstrated that sensory feedback from the cutaneous receptors of the foot sole plays an important role in maintaining balance. However, it is not yet known clearly to what extent the sensory impairment seen in MS patients affects balance and gait disorders. The aim of this study is to examine the relationship between lower extremity position sense and foot sole sense with gait and balance in MS patients.
