Abstract
|
|
|
Background: New-onset refractory status epilepticus (NORSE) occurs in people without a history of seizures. In these cases, the seizure causes are unclear, and the seizures are not controlled by standard treatment. Autoimmune encephalitis (AIE) can be a cause of NORSE. Cryptogenic NORSE may be associated with AIE, but antibodies associated with the condition have not yet been identified. Primary immunotherapy may not be effective for AIE. Rituximab has improved the prognosis in some cases.
Case Report: We treated a cryptogenic NORSE patient with a combination of antiepileptic drugs and immunotherapy. On the 13th hospital day, the seizures were controlled, but the patient remained in a coma. The patient rapidly recovered after administration of rituximab started on the 26th hospital day.
Conclusion: Rituximab may be helpful for cryptogenic NORSE patients in whom primary immunotherapy controls seizures, but fails to improve consciousness.
