AbstractFebrile infection-related epilepsy syndrome (FIRES) is a subset or variant of new-onset refractory status epilepticus in children. FIRES is characterized by the occurrence of a febrile episode between 24 hours and 2 weeks before the onset of refractory status epilepticus. A infectious cause is rarely identified in FIRES and an inflammatory or autoimmune etiology is implied. Seizures in FIRES are very difficult to control, and treatments include antiepileptic drugs, ketogenic diet, intravenous immunoglobulin, plasmapheresis, and corticosteroid therapy. The prognosis for patients with FIRES is poor, and most children are left with refractory epilepsy and cognitive impairment. The new consensus guidelines on the terminology of FIRES and recent interest in new treatment approaches have been welcome developments for clinicians who face the challenge of diagnosing and managing status epilepticus in a previously healthy child that occurs following a minor febrile episode. This review aims to provide clinicians with an update on the current hypotheses for the etiology, pathogenesis, clinical evaluation, management, and future directions in the diagnosis and treatment of FIRES.
