Filter by:New therapeutic approaches of MS are emerging, targeting different actors of the immune system. Some of them target a specific population of white blood cells: B lymphocytes composed of different subpopulations. The subsets of B cells express different functional properties that control the immune response, but these regulation mechanisms have yet to be clearly described. Some subpopulations could amplify inflammation through IL-6 production for example, whereas some ones contribute to its regulation through the production of IL-10. Using samples collected in a large cohort of individuals with risk of MS and treatment-naive patients in the early onset of the disease, the investigators aim to develop a 2 year follow-up study of the different blood B cells subset distribution and their functional properties in terms of pro- and anti-inflammatory cytokine production in MS. This approach can identify new biomarkers for monitoring of MS patients and lead to better define the indication use of depletive B cell drugs and not to counteract the regulatory action of these cells.
The purpose of this trial was to compare two doses of abituzumab with placebo and determine whether abituzumab was more effective, safer, would be better tolerated and could provoke better immune response than placebo in the treatment of participants with SSc-ILD who already receive constant doses of mycophenolate.
Scleroderma is an autoimmune disease with skin manifestations and may have pulmonary involvement. Obstructive sleep apnea (OSA) may also be seen in scleroderma. Less is known regarding the prevalence of OSA in scleroderma and its association with pulmonary involvement.
Digital ulcers (DUs) in scleroderma result from recurrent Raynaud's phenomenon (RP) and microtrauma with high impact on quality of life, management of DUs is a great challenge for clinicians. Medical use of ozone (triatomic oxygen) was initiated in the 19th century. Ozone has multiple therapeutic effects in wound healing due to the property of releasing nascent oxygen, which has been shown to stimulate antioxidant enzymes.
The purpose of this phase 2 multicenter, randomized, double-blind, placebo-controlled, study is to assess the safety and efficacy of ifetroban in patients with diffuse cutaneous systemic SSc (dcSSc) or SSc-associated pulmonary arterial hypertension (SSc-PAH).
This is a prospective open-label trial that will enroll 12 patients with systemic sclerosis (SSc) and at least one calcinotic lesion of the hands that is palpable on physical examination and also measureable on hand radiographs, at one single center. Each subject will receive treprostinil orally for 12 months, and follow-up evaluations will be performed every 3 months. Our main objective is to determine whether oral treprostinil is safe, and effective in reducing calcinosis in patients with SSc. We hypothesize that calcinosis is a result of microvascular injury and ischemic damage, and that therefore treprostinil may be beneficial in the treatment of calcinosis in patients with SSc.
This research project has the overall objective to investigate the direction of the associations between illness perceptions, their influencing factors and health-related outcomes. Moreover, the investigators want to look at the direction of the associations between illness perceptions and health related outcomes such as psychological and physical functioning in patients with Systemic Lupus Erythematosus (SLE) and Systemic Sclerosis (SSc). The investigators want to know whether the outcome variables anxiety, depression, physical (dis) functioning are influenced by illness perceptions or vice versa. Not only the patients' illness perceptions but also the illness perceptions of the General Practitioners (GP) and rheumatologists will be investigated. The researchers want to know if the doctors' perceptions have an impact on the physical and psychological functioning of the patient or vice versa. Much research in the field of illness perceptions is cross-sectional in nature which means that the direction of the relationships between variables is not known.
This study evaluates the efficacy and safety of routine medical treatments of digital ulcers in patients with systemic sclerosis in a prospective cohort study.
Systemic Sclerosis (SSc) is an auto-immune systemic disease characterized by vascular damage, cutaneous and visceral fibrosis and a dysimmune condition. Therapies in this disease remain insufficient and the complications resulting from organs involvement lead to strong morbi-mortality.The dermic infiltrate of the patients includes a strong proportion of Tcells. T cells and Natural Killer (NK) cells are potentially involved in the vascular damage of the SSc. However mechanisms at the onset of this endothelial cytotoxicity and its impact on the capacities of regeneration of the endothelial tissue remain poorly understood. Fractalkine is at the same time an endothelial membrane-bound adhesion molecule and a chemokine which is able to bind CX3CR1 expressed by the immune populations. The purpose of the project is to define the role displayed by cytotoxic, circulating immune populations of SSc patients in endothelial cytotoxicity as well as the role of the axis Fractalkine / CX3CR1 in mediating the interactions between the immune cytotoxic cells and the endothelium.
Hands are commonly affected in Systemic Sclerosis (SS). The objective of this research is to apply a home based hand care guide in patients with SS and to evaluate its response regarding hand pain, function, strength and mobility.
