This is a clinical trial to determine the feasibility of a stationary aerobic cycling intervention and explore if aerobic exercise independently promotes remyelination in people with multiple sclerosis (MS).
Glial fibrillary acidic protein (GFAP)-Immunoglobulin G (IgG) have recently been described as a biomarker of a novel inflammatory central nervous system (CNS) disorder, termed autoimmune GFAP astrocytopathy. Thus far, four major clinical series have been published (two from Mayo Clinic USA, one from Italy and one from China). GFAP-IgG detected in serum or in cerebrospinal fluid, by tissue-based assay and confirmed by cell-based assay, are associated with encephalitis or meningoencephalitis of acute or subacute onset, less frequently with myelitis or optic disk edema. The characteristic MRI feature is brain linear perivascular radial gadolinium enhancement in the white matter perpendicular to the ventricle, consistent with the immunohistochemical staining pattern of GFAP in rodent brain sections. Approximately 20% of reported cases are associated with a neoplasm (ovarian teratoma mostly). Coexisting neural autoantibodies are described in some patients, N-methyl-D-aspartate (NMDA)-receptor (R)-IgG mostly, followed by aquaporin 4 (AQP4)-IgG. The disease is usually corticosteroid responsive although relapse can occur. In contrast, Chinese patients display poorer outcomes. Pathophysiology is not well understood but the intracellular antigen location makes GFAP-IgG unlikely pathogenic whereas animal models and neuropathologic data suggest a T-cell immune-mediated disorder. The aim of the investigators is to report the first French cohort of patients GFAP-IgG positive. Investigators retrospectively assessed clinical, immunological and radiological features, treatment response and outcomes.
Spermatogonial stem cell transplantation through ultrasound guided rete testis injection and testicular tissue grafting will be performed for participants who have frozen testicular tissue prior to gonadotoxic therapy. The purpose of this study is to test the safety and feasibility of these transplant technologies and restore fertility for these participants.
This study will provide further insights into the natural course of Inflammatory demyelination disease including clinical features，progression, related antibody spectrum and drug treatment effect
Since December 2019, an international outbreak of respiratory illnesses caused by SARS-CoV-2 called covid-19 has become a global challenge. In France, while the first cases were reported in January, more than 20 000 cases were confirmed at end of March. Early estimations from epidemiological data seem to show that 18-20% of patients with confirmed covid-19 are admitted in an intensive care unit (ICU). Patients with chronic inflammatory rheumatism, auto-immune or auto-inflammatory rare and non-rare diseases are susceptible to severe covid-19 (i.e ICU) due to the specific therapeutic management of their illness (corticosteroid, immunosuppressive and immunomodulatory drugs,..). No data are available for this particular population in France. This retrospective multicentre observational study aims to evaluate the frequency of severe forms of covid-19 and risk factors associated with specific outcomes in covid-19 in patients with chronic inflammatory rheumatism, auto-immune or auto-inflammatory rare and non-rare diseases.
Several clinical studies have shown that rituximab is safe and effective for the induction of remission in moderate to severe systemic lupus erythematosus, and has been recommended by several guidelines for the induction of remission in refractory lupus with important organ involvement. However, there are few studies on the use of rituximab in the long-term maintenance and remission of the disease. There is no recognized scheme for the dose, interval and course of treatment of the drug. In this study, patients with moderate and severe systemic lupus erythematosus who achieved remission after standardized treatment were randomly divided into two groups at 1:1 and followed up every 3 months for 24 months. The basic situation and disease activity score of each subject were recorded. The recurrence rate of each observation group was calculated, the influencing factors of disease recurrence were analyzed, and a more reasonable drug use scheme was explored.
Evaluation and prediction of relapse risk after glucocorticoid or immunosuppressant withdrawal in patients with stable IgG4 related disease: a prospective cohort study from china.
The purpose of this study is to better understand how the treatment of cancer with immune checkpoint inhibitors (ICI) leads to the development of autoimmunity. Specifically, we wish to understand the genetics and immune system features that cause a subset of cancer patients treated with checkpoint inhibitor therapy to develop an immune-related adverse event (irAE).
This study will compare the pattern of Th17 immune response in active and inactive pemphigus subjects. Skin and serum samples will be taken at the moment of enrollment.
