Active clinical trials for "Sclerosis"

The aim of the study is to investigate reliability, validity, and responsiveness of the Static Balance Test in patients with 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.

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.

Ocrelizumab is FDA approved for therapy of multiple sclerosis (MS). It depletes B cells and stops MS inflammation.

The study team propose that a new, hand-held test device may be valuable in the management of breathing failure in patients with Motor Neurone Disease (MND). The study team need to validate this device against the current gold standard of blood gas analysis and determine whether people with MND can use it at home. The new device, called 'N-Tidal C™' measures the carbon dioxide (CO2) in expired breath. At the end of the breath (end tidal) the CO2 level gives an indication of the CO2 in the person's arterial blood. Ventilatory failure is diagnosed at present using the value of CO2 in the arterial blood, but usually this can only be measured in specialist clinics. The study will determine if the end tidal CO2 measured by the new device agrees with CO2 measured on a blood test in clinic and also whether or not the device is practical for home use. The team will analyse the output of the device during home monitoring to see if changes in the pattern of CO2 in the expired breath identify, or even predict, the development of breathing failure in the community. With the results of these measures and detailed information about the patients in Papworth's clinic, recruited to this study, collected over a year the team will design a follow on study to see if using the new device at home can improve survival and quality of life for people with MND.

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.

The research is aimed to asses the validity of the communication system improving the quality of life and the degree of sanctification of clinical patients and their caregiver.

Eosinophils are involved in tissue remodeling and fibrosis in many inflammatory diseases. Systemic sclerosis (SSc) is an autoimmune disease with fibrotic skin and lung complications. The profibrosing properties and data from the SSc literature suggest a possible role of the eosinophils in the process of fibrogenesis of SSc.

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.

Interstitial lung diseases (ILDs) are a heterogeneous group of disorders, which encompass a wide range of conditions. In some patients with fibrosing ILDs, a progressive phenotype similar to that observed in idiopathic pulmonary fibrosis (IPF) may develop during the course of the disease (PF-ILD), including patients with systemic sclerosis (SSc)-related ILD. The aim of the study is to estimate the incidence and prevalence and to describe the characteristics of patients diagnosed with non-IPF PF-ILD and SSc-ILD, to describe the natural course of disease, and to explore the correlation between mortality and Forced Vital Capacity (FVC) of the patients with non-IPF PF-ILD. This study will be based on two data sources: the French national medico administrative database (SNDS) and the ILD cohort from the National French center for rare pulmonary diseases in Lyon, France.
