ABSTRACT
New onset refractory status epilepticus (NORSE) and its subcategory, febrile infection-related epilepsy syndrome (FIRES) are rare and devastating conditions, initial symptoms of which are often refractory status epilepticus. NORSE/FIRES is characterized by high mortality and disability, but unfortunately, due to the unclear pathogenesis, the diagnosis and treatment of NORSE/FIRES are very challenging. This editorial aims to summarize the key points and recent developments in the etiology, pathophysiology, diagnosis and management of these challenging conditions.
ABSTRACT
Febrile infection-related epilepsy syndrome(FIRES)is a lethal encephalopathy with refractory status epilepticus as the main manifestation,and the selection of effective antiepileptic drugs(AEDs)is the focus and difficulty of treatment.This review summarises the mechanism of action,drug administration and adverse effects of different anti-inflammatory immunotherapies in the treatment of this disease,and finds that early initiation of ketogenic diet(KD)is one of the most effective treatments at present,and further studies are needed to clarify the adverse effects of the drugs and the effects of the combination of different drugs.
ABSTRACT
Objective:To investigate the clinical features, diagnosis and treatment of febrile infection-related epilepsy syndrome.Methods:The data of 3 children with febrile infection-related epilepsy syndrome admitted to the First Affiliated Hospital of Zhengzhou University from May to June 2019 were collected retrospectively, and their clinical characteristics, diagnosis, treatments and prognosis were summarized in combination with relevant literature.Results:The age of onset was 6-9 years old.The time interval from fever to first convulsion was 4-7 days, and they progressed to status epilepticus within 24 hours.The seizures were mainly multifocal seizures.Cerebrospinal fluid laboratory examination was normal.Electrocardiogram shows diffuse slow wave activity as the background, and epileptic waves dominated by the temporal area.Cranial magnetic resonance imaging showed signs of edema in 2 cases during the acute phase.All patients were resistant to multiple (4-5) anti-epileptic drugs, but high-dose anesthetic drugs can effectively terminate status epilepticus.All cases developed into refractory epilepsy, 2 cases had cognitive impairment and 1 case had movement impairment after 1 year.Conclusion:Febrile infection-related epilepsy syndrome often occurs in school-age children who have been physically healthy, which was included by fever.The seizures are explosive and refractory in febrile infection-related epilepsy syndrome, and it lacked specific laboratory indicators.High-dose anesthetics can effectively terminate status epilepticus, but it always has a poor prognosis.
ABSTRACT
New-onset refractory status epilepticus(NORSE) is a clinical syndrome, not a specific diagnosis of diseases in patients with new onset of refractive status epilepticus without active epilepsy or other preexisting relevant neurological disorders and is not associated with a clearly acute or active structrue, toxic or metabolic cause.Febrile infection-related epilepsy syndrome(FIRES) is a subcategory of NORSE, applicable for all ages, occurring in a prior febrile infection starting between 24 hours and 2 weeks before onset of refractory status epilepticus(RSE) with fever or not.Proposed consensus definitions are also applicable for infantile hemiconvulsion-hemiplegia and epilepsy syndrome, RSE, super-RSE, prolonged RSE and prolonged super-RSE.These consensus definitions will promote much more effective communication and multicenter research, and ultimately improve recognition and treatment of these conditions.
