Filter by:Systemic SClerosis (SSC) is a systemic disease characterized by limited or diffuse cutaneous sclerosis, microangiopathy, overproduction of autoantibodies and variable organ damage due to vasculopathy and/or fibrosis. The loss of self-tolerance is believed to be caused by the dysregulation of both innate and adaptive immune systems and may involve Reactive Oxygen Species (ROS). Neutrophils are potent producers of ROS and may play a role in endothelial cells and fibrobasts dysfunction, as in autoantibodies generation. However, their role in SSC pathogenesis remains to be determined. Recent studies discovered abnormal regulation of Neutrophil Extracellular Traps (NETs) in other auto-immune diseases such as Systemic Lupus Erythematosus (SLE). NETs are web-like structures composed of chromatin backbones and granular molecules. They are released by activated neutrophils through a process called "NETosis". Nets were first described in 2004 as a novel host defense mechanism to trap and kill foreign pathogens. Recent evidence shows that NETs also participate in the pathogenesis of a variety of inflammatory and autoimmune diseases, including SLE. The investigators recently highlighted this phenomenon in SSc, especially in patients with vascular complications and/or at a early stage of the disease. The investigators will now explore the factors implicated in this dysregulation of NETosis in SSc.
The investigational product is designed to effectively combat B cells in patients with autoimmune diseases. Autologous T cells enriched with CD4/CD8 are genetically engineered using a lentiviral vector to express chimeric antigen receptors (CARs) that target the CD19 antigen on the cell surface of B cells and their precursors. During treatment, patients undergo leukapheresis, lymophodepleting chemotherapy and administration of the expanded CD19-CAR-transduced T cells.
This study aims to collect information on rheumatology patients' dietary habits, autoimmune disease activity, dietary changes, disease symptom improvements, and perceptions on their dietary habits and how it affects their autoimmune disease. The main objective is to see if rheumatology patients change their dietary habits after their diagnosis of an autoimmune disease and if it subjectively improved their disease symptoms. It will also look at rheumatology patients' expectations for their rheumatologist when it comes to dietary advice and what resources they used to choose their new dietary habits. The study also seeks to measure the interest that rheumatology patients have in pursuing dietary changes as a means of controlling the symptoms of their autoimmune disease. It is expected that patients who changed their eating habits to healthier diets such as a Mediterranean diet would report less severe autoimmune disease symptoms. There are limited dietary recommendations for the management of many rheumatological diseases, so this study seeks to assess rheumatology patients' willingness to try dietary modifications, what improvements they had, and why they decide to make these changes in light of limited information.
The purpose of this study was to analyze the relationship between the microbial community, host immunity and the presence or absence of concurrent rapidly progressive interstitial lung disease patients with anti-MDA5 antibody positive dermatomyositis.
RESET-Myositis: Open-Label Study to Evaluate the Safety and Efficacy of CABA-201 in Subjects with Active Idiopathic Inflammatory Myopathy
To detect the changes of lymphocyte subsets in peripheral blood of non-myopathic dermatomyositis with pulmonary interstitial disease, classical dermatomyositis with pulmonary interstitial disease, rheumatism with non-inflammatory myopathy with pulmonary interstitial disease and healthy adults among the 4 groups, and to detect the related cytokines secreted by lymphocyte subsets Th1,Th2 and Th17. Clinical features, distribution of peripheral lymphocyte subsets ratio and related cytokine content secreted by each lymphocyte subset were analyzed in each group, so as to explore the pathogenesis characteristics of nonmyopathic dermatomyositis complicated with pulmonary interstitial disease, in order to facilitate clinical guidance for diagnosis and treatment.
This is a single arm study to evaluate the efficacy and safety of CD19 targeted CAR-T cells therapy for patients with Refractory Autoimmune Disease
The purpose of this study is to measure the long-term safety and tolerability of efgartigimod PH20 SC in adult participants with IIM who previously participated in ARGX-113-2007. Secondary objectives include efficacy measures of efgartigimod PH20 SC in participants with IIM.
The purpose of the study is to understand how the study medicine PF-06823859 works in people with idiopathic inflammatory myopathies (DM and PM). These disorders cause inflammation that weakens the muscles that are important for movement and may also cause skin rash in people with DM. This study is seeking participants who: - Are 18 years of age or older or minimum legal adult age as defined per local regulation, whichever is greater - Have active DM or active PM. - Are receiving a stable dose of 1 corticosteroid taken by mouth and/or 1 traditional immunosuppressant. - Note: Corticosteroids and immunosuppressants are medicines that help reduce inflammation and may signal to the immune system not to attack the body. Dermatomyositis (DM) is a rare disease that causes muscle inflammation that results in muscle weakness and low muscle stamina. Patients with DM have a characteristic skin rash. Polymyositis (PM) is a rare disease that involves mainly muscle inflammation resulting in muscle weakness, that can sometimes be painful. Patients with DM and PM may have trouble going up the steps, walking or getting to a standing position. Some of the participants will receive the study medicine (PF-06823859) and some will receive placebo (which is similar to study medicine but contains no medicine in it). The study medicine or placebo will be given as an intravenous (IV) infusion (directly into the veins), which takes about1 hour; every 4 weeks from Day 1 to Week 48 of the study. Both PF-06823859 and placebo and will be given at the study site. The study will compare the experiences of people receiving study medication to those of the people who do not. This will help to see if PF-06823859 is safe and effective. Participants will take part in this study for about 13 months. During this time, participants will have 15 study visits. These visits will be performed at the study site.
Introduction: Patients with autoimmune rheumatic diseases (ARDs), rheumatoid arthritis (RA), juvenile idiopathic arthritis (JIA), psoriatic arthritis (PAs), ankylosing spondylitis (AS), systemic lupus erythematosus (SLE), primary Sjögren's syndrome (pSS) , systemic sclerosis (SSc), idiopathic inflammatory myopathies (IIM) and primary vasculitides, have a high risk of herpes zoster (HZ) infection. This increased susceptibility is caused by a deficient cell-mediated immune response due to the underlying disease and glucocorticoid and immunosuppressive treatments that impair the T-cell response, including conventional and unconventional synthetic disease-modifying anti-rheumatic drugs (DMARDs) and biological agents. In this context, the recent availability of a recombinant vaccine against HZ (RZV or Shingrix®), composed of recombinant VZV glycoprotein E (gE) and the AS01B adjuvant system (HZ/su), is a major progress regarding safety for immunosuppressed patients. Its effectiveness, however, has been clearly demonstrated for non-immunosuppressed patients and in selected populations of immunocompromised individuals. There are no prospective controlled studies evaluating the immunogenicity of RZV and its impact on the activity of the underlying disease, as well as its safety in patients with ARDs at high-risk for HZ. Hypothesis: RZV has a good safety profile, including with respect to underlying rheumatic disease activity, in patients with ARDs at high risk of HZ. Objectives: Primary: To assess the short-term safety profile in relation to underlying disease activity in patients with ARDs at high risk of HZ immunized with RZV compared to unvaccinated patients. Secondary: To evaluate the general safety of the vaccine in patients with ARDs at high risk of HZ immunized with RZV and non-immunosuppressed control subjects (CG); the humoral and cellular immunogenicity of RZV in patients with ARDs at high risk of HZ compared to CG; the influence of disease treatment on vaccine response; the 12-month persistence of humoral immunogenicity and incident cases of HZ. Specific studies will also be carried out to evaluate the effect of drug withdrawal (methotrexate-MTX and mycophenolate mofetil-MMF) after vaccination in increasing the immune response in patients with ARDs with controlled underlying disease.
