Refractory myasthenia gravis.
Myasthenia gravis (MG) is an autoimmune disorder in which antibodies are produced that target and destroy nicotinic acetylcholine (ACh) receptors at the neuromuscular junction of striated muscle cells [ Drachman, 1994 ]. Although the disease is rare, its prevalence has continued to rise over the past 50 years.
