This leads to impaired neuromuscular transmission and subsequent fluctuating fatigability and weakness of ocular, bulbar, and limb skeletal muscles. 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.

Myasthenia gravis (MG) is an autoimmune disorder affecting neuromuscular transmission. It is caused by antibody mediated attacks on the nicotinic acetylcholine receptors (AChR), muscle specific tyrosine kinase (MuSK), and various other novel targets like anti-lipoprotein-related protein 4 (LRP4). 1,2 It is treated …All the above-mentioned favorable outcomes of rituximab in refractory myasthenia gravis patients have widened the options for treatment of refractory myasthenia gravis; they have also demonstrated that RTX could improve patients' quality of life by decreasing dose-related adverse effects and sustaining remission [10,12-17]. …
