Refractory myasthenia gravis: the more we learn, the less we know.

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 unmet needs in our understanding of this disease subset. This review raises questions about our current understanding of refractory disease and how emerging data as well as therapies may alter our thinking and patients’ disease course.
