Myasthenia gravis (MG) is a rare autoimmune disease characterised by antibody-mediated interference with neuromuscular transmission at the neuromuscular junction [].MG is classed as a rare disease, and its prevalence is estimated to be about 1–2 per 10,000 people [].However, reported incidence rates are increasing, partly due to …Approximately 15% of patients with generalized myasthenia gravis (gMG) do not respond to standard immunosuppressive therapies (ISTs), or require intravenous immunoglobulin (IVIg) or plasma exchange (PLEX) to manage their symptoms. 1 –3 For these patients with treatment-refractory myasthenia gravis (MG), disease control is impaired; a study in ...Objective: To describe the clinical characteristics and outcomes in patients with refractory myasthenia gravis (MG) and to determine the effectiveness and side effects of the drugs used for their treatment. Methods: This observational retrospective cross-sectional multicenter study was based on data from the Spanish MG Registry (NMD-ES).Myasthenia gravis (MG) is a rare, chronic, debilitating autoimmune disease arising from impaired neuromuscular transmission [1,2,3,4].MG is characterized by fluctuating muscle weakness and by exertional and potentially disabling fatigability [1, 5].It is a heterogeneous condition that may cause localized (most commonly ocular) muscle weakness, but is more …Abstract: Introduction: Myasthenia gravis, an autoimmune disorder of neuromuscular transmission, is treated by an array of immunomodulating therapies.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.It is …We report on a patient with refractory Myasthenia gravis with acetylcholine receptor antibodies with two prior myasthenic crises suffering from COVID-19 with rapid evolving weakness and respiratory failure. Respiratory failure developed and prolonged mechanical ventilation was necessary. After plasmapheresis, residual, severe …The initial phase 2 trial (NCT00727194), sponsored by Alexion Pharmaceuticals, was a prospective, double-blind, placebo-controlled crossover design of 14 AChR+, gMG treatment-refractory patients [Myasthenia Gravis Foundation of America (MGFA), Classes II–IVa)] initially treated for 16 weeks (Period 1) followed by a 5-week …Generalized myasthenia gravis (gMG) is a rare, chronic, and debilitating autoimmune disease. Activation of the complement system by autoantibodies against the postsynaptic acetylcholine receptor (AChR) leads to destruction of the postsynaptic membrane and disruption of neuromuscular transmission. This trial evaluated ravulizumab, a long-acting ...Objective: To evaluate whether eculizumab helps patients with anti-acetylcholine receptor-positive (AChR+) refractory generalized myasthenia gravis (gMG) achieve the Myasthenia Gravis Foundation of America (MGFA) post-intervention status of minimal manifestations (MM), we assessed patients' status throughout REGAIN (Safety and Efficacy of Eculizumab in AChR+ Refractory Generalized Myasthenia ...Objectives: Myasthenia gravis (MG) is an immune-mediated neuromuscular disorder responsive to immunomodulatory treatments. 10–20% of MGs are not responsive to conventional first-line therapies. Here, we sought to investigate the efficacy and safety of rituximab therapy in the treatment of patients with refractory MG.Methods: In a 48-week, …Myasthenia gravis (MG), a prototype autoimmune neurological disease, had its therapy centred on corticosteroids, non-steroidal broad-spectrum immunotherapy and cholinesterase inhibitors for several decades. Treatment-refractory MG and long-term toxicities of the medications have been major concerns with the conventional therapies.Side effects, which usually are mild, can include chills, dizziness, headaches and fluid retention. Monoclonal antibody. Rituximab (Rituxan) and eculizumab (Soliris) are medicines given by vein for myasthenia gravis. These medicines are usually used when other treatments don't work. They can have serious side effects.Our patient has had a refractory course with respect to myasthenia gravis. Other options for treatment of refractory myasthenia gravis include rituximab, high-dose cyclophosphamide and eculizumab . Given our patient’s progression of both autoimmune diseases, we explored the possibility of hematopoietic stem cell transplant (HSCT).Mar 1, 2019 · 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. Jan 1, 2021 · This updated formal consensus guidance of international MG experts, based on new evidence, provides recommendations to clinicians caring for patients with MG worldwide. Evidence-based recommendations for the treatment of myasthenia gravis (MG) have historically been difficult to develop because of limited evidence from studies with a low risk ...

Introduction Patients with generalized myasthenia gravis (gMG) experience functional impairment due to MG symptoms. This study aimed to assess, from the patient perspective, the symptoms, impacts, and treatment goals of individuals diagnosed with gMG. Methods Semi-structured, in-depth concept-elicitation interviews were conducted with 28 individuals diagnosed with gMG in the United States ...May 9, 2022 · A retrospective, longitudinal, cohort study was conducted of patients in England aged ≥ 18 years with treatment-refractory or non-refractory MG, using data recorded during 1997–2016 in the Clinical Practice Research Datalink and the Hospital Episode Statistics databases. A control cohort of patients without MG, matched to the patients in ...

Myasthenia gravis (MG) is a rare autoimmune disease characterised by antibody-mediated interference with neuromuscular transmission at the neuromuscular junction [].MG is classed as a rare disease, and its prevalence is estimated to be about 1–2 per 10,000 people [].However, reported incidence rates are increasing, partly due to …Symptoms The following symptoms are commonly associated with myasthenia gravis: Weakness of the eye muscles (ocular myasthenia) Drooping of one or both eyelids (ptosis) Blurred or double vision (diplopia) Changes in facial expressions Difficulty swallowing Shortness of breath Impaired speech (dysarthria)Refractory myasthenia gravis identifies the group of patients that have inadequate symptom control and persistent muscle weakness and fatigability despite the use of multiple immune modulatory therapies. This manuscript highlights what is currently known about refractory myasthenia gravis and underlines major knowledge gaps, drawing attention to the ……
