Refractory myasthenia gravis

Myasthenia gravis (MG) is a rare classic autoimmune disease where immunosuppressant therapies have been successful to reduce MG attributable mortality fairly well. However, patients with refractory MG (rMG) among the actively treated MG (aMG) are nonresponsive to conventional therapy and display high disease severity, which calls for further ....

Abstract. Muscle-specific tyrosine kinase (MuSK) myasthenia gravis (MG) is a rare, frequently more severe, subtype of MG with different pathogenesis, and peculiar clinical features. The prevalence varies among countries and ethnic groups, affecting 5–8% of all MG patients. MuSK-MG usually has an acute onset affecting mainly the facial-bulbar ...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.

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 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 …

Myasthenia gravis results from an autoimmune attack on postsynaptic acetylcholine receptors, which disrupts neuromuscular transmission. The trigger for autoantibody production is unknown, but the disorder is associated with abnormalities of the thymus, autoimmune hyperthyroidism, and other autoimmune disorders (eg, rheumatoid arthritis …Myasthenia gravis (MG) is a neurological B-cell mediated autoimmune disorder affecting the neuromuscular junction. MG therapeutics have always relied on nonselective immunosuppression with oral steroids and non-steroidal immunosuppressants, mainly with good clinical response.

Impact of Ravulizumab on Patient Outcomes and Quality of Life in Generalized Myasthenia Gravis. Abstract: Myasthenia gravis (MG) is an autoimmune ion channel disorder in which antibodies to different end-plate antigens impair neuromuscular transmission, ultimately leading to muscle weakness and fatigability.Background and purpose: Defining refractory myasthenia gravis is important, as this can drive clinical decision making, for example, by escalating treatments in refractory individuals. There are several definitions of refractory myasthenia, and their performances have not been compared. Having valid and reliable criteria can help select patients in …
