Filter by:This study aims to identify clinical and biological determinants and factors that predict outcome including primary outcome (percentage of changes in clinical scales pre- and after 3 months ) and secondary outcome depending on neurophysiologiacal studies and prognostic factors in individual patients with Guillain-Barre syndrome i individuals managed by plasmapheresis and IVIG immunoglobulin . This information will be used to understand the diversity in clinical presentation and response to treatment of GBS.
This is an observations study evaluating safety and efficacy of immunoadsorption compared to plasma exchange in Guillain-Barré Syndrome.
The aim of this retrospective observational single-center cohort study is to gain a deeper understanding regarding the frequency, the clinical and electrophysiologic characteristics (e.g., the diagnostic work up), complications, treatment regimes, and their associations with specific courses of disease and outcomes in adult patients with the suspected or proven diagnosis of GBS.
This is a Phase 3, prospective, multicenter, placebo controlled, double blind, randomized study to investigate the efficacy and safety of eculizumab in participants with severe GBS, defined using the Hughes Functional Grade (FG) scale as progressively deteriorating FG3 or FG4/FG5 within 2 weeks from onset of weakness due to GBS. This study will be conducted only at sites in Japan.
This study is intended to evaluate the efficacy and safety of ANX005 administered by intravenous (IV) infusion to participants recently diagnosed with Guillain-Barré Syndrome (GBS). The total duration of study participation is approximately 6 months.
Demyelinating diseases represent a broad spectrum of disorders and are induced by excessive inflammation most often triggered by an autoimmune mechanism. Some of these pathologies are chronic and affect the central nervous system such as multiple sclerosis (MS), others are monophasic and target the peripheral nervous system such as Guillain Barré syndrome (GBS). In neuroinflammatory pathologies, the excessive response of the pro-inflammatory Th1 and Th17 lymphocyte lines and the insufficient response of regulatory T lymphocytes (Treg) cause excessive inflammation which is deleterious to the nervous tissue. The regulation of these signaling pathways involves key proteins such as kinases. Modulation of these kinases which could allow the development of new pharmacological targets for neuroinflammation. Recent work (unpublished data) has shown an association between the expression of ERK5 and PMK2 kinases, and the clinical severity of experimental allergic encephalomyelitis, a mouse model that mimics multiple sclerosis. In order to search for new biomarkers and improve our knowledge of the actors of the initial inflammatory phase of neuroinflammatory pathologies, we propose to study the differences in expression of ERK5 and PKM2 kinases in the blood and cerebral spinal fluid (CSF) of patients followed for relapsing-remitting MS and GBS by both RT-qPCR and protein quantification. We also want to study other biological parameters which include characterization of the pro / anti-inflammatory balance by cytokine assay and lymphocyte phenotyping, metabolome study, and mild form neurofilament (NfL) assay.
1. study the pharmacokinetics of mini-pooled intravenous immunoglobulin( MP-IVIG) 2. to determine the efficacy of intravenous immunoglobulin (IVIg) in hastening recovery and reducing the complications of Guillain-Barré syndrome (GBS). - The MP-IVIG was tolerated and presented no safety issues in a previous study and we will be confirmed by monitoring any adverse events (anaphylaxis and haemolysis) ( no or mild or moderate) and reporting them to ethical committee safety monitoring group. - Efficacy will be confirmed by: 1. Patient able to walk 2. Improvement of general health. 3. Integration in to social live 3. to compare the efficacy of IVIg to plasma exchange (PE) in hastening recovery and improving the condition of GBS
Guillain-barre syndrome (GBS) is an acute immune-mediated polyneuropathy. Intravenous Gamma globulin is an effective therapy.Although high doses of gamma globulin are clinically effective, the patient's recovery and clinical prognosis vary. The establishment of a cohort study on the therapeutic effect of gamma globulin in Guillain-barre Syndrome is beneficial to the diagnosis of the disease and to the understanding of the natural course of the disease and the efficacy of drug treatment.
The nodes of Ranvier contain ion channels that enable the rapid propagation of the nerve impulse. Cell adhesion molecules and glycolipids play an important role in the formation of the nodes of Ranvier. Antibodies against glycolipids are detected in half of patients with Guillain-Barré syndrome, an acute inflammatory neuropathy affecting peripheral nerve. The investigators found that antibodies target cell adhesion molecules at nodes of Ranvier in 10% of patients with chronic inflammatory demyelinating neuropathy (CIDP), another disabling neuromuscular disease affecting peripheral nerves. In the majority of patients with GBS or CIDP, the mechanisms responsible for the neuromuscular disorders are unknown. Our goals are to identify novel targets of antibodies in patients, this in order to find novel bio-markers and to better understand the physiopathology of inflammatory neuropathies. This work will help patient diagnosis and treatment orientation.
Neuromuscular US will be a good and non invasive predictor for respiratory and autonomic dysfunctions in GBS through evaluation of diaphragmatic thickness, phrenic and vagus nerve cross sectional area.
