Epidemiological profile of myasthenia gravis in South Korea using the national health insurance database.

Based on the national registry data from 2010 to 2018, the incidence and prevalence rate in South Korea has increased. Whereas the use of IVIG has remained stable, thymectomy is performed earlier than before, and the distribution of immunosuppressant therapies has changed over the years with an increase in tacrolimus and mycophenolate mofetil. We expect that this study will serve as a basis for future South Korean MG epidemiological studies.
