Abstract
Myasthenia gravis (MG) is an autoimmune disorder affecting postsynaptic membranes in neuromuscular junctions, presenting as fatigable muscle weakness. Myasthenic crisis is a life-threatening complication characterized by severe respiratory insufficiency necessitating invasive or noninvasive ventilation. Two rapid therapies used to manage myasthenic crises are intravenous immunoglobulins (IVIg) and plasmapheresis (PLEX). Their comparative effectiveness remains equivocal. Our article examines evidence from several clinical trials and observational studies, in order to determine the superiority of one treatment over the other. Multiple factors can complicate the choices between two treatments. We concluded that the choice between PLEX and IVIg is multifaceted, guided by individual patient characteristics, institutional resources, and clinician preference. While PLEX can be considered as first-line for rapid clinical outcomes, it is hard to pick one treatment over the other, and careful consideration of comorbidities and resource availability is crucial. Our article highlights the need for further research to establish definitive guidelines and enhance patient outcomes in myasthenic crisis patients.
