The humanized monoclonal antibody eculizumab (Soliris ®) is a complement inhibitor indicated for use in anti-acetylcholine receptor (AChR) antibody-positive adults with generalized myasthenia gravis (gMG) in the USA, refractory gMG in the EU, or gMG with symptoms that are difficult to control with high-dose IVIg therapy or PLEX in Japan. Introduction: Approximately 10-20% of patients WITH myasthenia gravis (MG) are refractory to conventional immunotherapies. The purpose of this study was to conduct a systematic review and meta-analysis to explore the optimal therapies for refractory MG.Method: Correlative studies were performed through a search in PubMed, Cochrane Library, and Embase databases.

Overview. Myasthenia gravis (MG) is an autoimmune disorder caused by antibodies that act against the myoneural junction. Conventional immunosuppressants such as corticosteroids, azathioprine and mycophenolate are associated with long-term side effects and many patients do not achieve remission and may become refractory.Refractory Myasthenia Gravis. Myasthenia gravis (MG) is an autoimmune condition in which the body mistakenly attacks itself. In MG, the way nerves and muscles communicate is affected. MG is treated with different drugs that either improve this communication or slow down the incorrect immune response.

Of all patients with MG, a fraction (estimated at 10%) have disease that is refractory to treatment with conventional agents such as cholinesterase inhibitors and immunosuppressive agents (including corticosteroids, azathioprine, and cyclosporine). 7 - 9 In this article, we review the natural course of MG, various definitions of the term treatme...In most patients with myasthenia gravis (MG), the disease is managed using immunosuppressive therapies (ISTs); however, 10%–15% of patients do not respond adequately to ISTs, experience intolerable adverse events, or require maintenance IV immunoglobulin or plasma exchange treatment. 1, –, 3 These patients are considered to have refractory MG, which can severely affect their health-related ...Clinical status and severity were determined by the recommendations of the Myasthenia Gravis Foundation of America. Results: Of 1388 patients with MG, 12 (0.9%) patients received eculizumab. A total of 11 patients who were anti-acetylcholine receptor antibody-positive with refractory gMG (M:F = 3:8) completed the 26-week treatment with eculizumab.Introduction Myasthenia gravis (MG) is a rare, debilitating, chronic disorder caused by the production of pathogenic immunoglobulin G autoantibodies against the neuromuscular junction. A lack of real-world studies in rare diseases reflects a relatively limited understanding of the significant unmet needs and burden of disease for patients. We aimed to provide comprehensive real-world insights ...

Myasthenia gravis (MG) is the most common disorder of neuromuscular transmission and is a prototypical autoimmune disorder. Most patients with MG are successfully treated with acetylcholinesterase inhibitors, corticosteroids, and/or steroid sparing agents such as azathioprine and mycophenolate mofetil.Myasthenia gravis (MG) is an autoantibody-mediated disease that compromises the acetylcholine receptors or associated structures of the postsynaptic membrane of the neuromuscular junction. This leads to impaired neuromuscular transmission and subsequent fluctuating fatigability and weakness of ocular, bulbar, and limb skeletal muscles.Refractory MG was defined as lack of response to treatment with prednisone and at least 2 immunosuppressants, inability to withdraw treatment without relapse in the last 12 months, or intolerance to treatment with severe adverse reactions. We identified 84 patients with MG, 11 of whom (13%) met criteria for refractory MG.Instagram:https://instagram. to commitmentbill format exampleelaboration lesson plandeb young Our patient has had a refractory course with respect to myasthenia gravis.
