Febrile infection-related epilepsy syndrome (FIRES), or acute encephalitis with refractory, repetitive partial seizures (AERRPS), is an epileptic encephalopathy beginning with fever-mediated seizures. The etiology remains unclear. To elucidate the genetic background of FIRES/AERRPS (hereafter FIRES), we recruited 19 Japanese patients, genotyped polymorphisms of the IL1B, IL6, IL10, TNFA, IL1RN, SCN1A and SCN2A genes, and compared their frequency between the patients and controls. For IL1RN, the frequency of a variable number of tandem repeat (VNTR) allele, RN2, was significantly higher in the patients than in controls (p=0...

Febrile infection-related epilepsy syndrome (FIRES) is a rare condition which evolves into refractory status epilepticus (SE), with poor outcome in most cases. Conventional antiepileptic drugs fail to control SE in FIRES patients. We report the case of a previously healthy 4-year-old boy who was diagnosed with FIRES. One week after pharyngitis and high fever he started seizures, followed by refractory SE. Benzodiazepines, phenytoin, high-dose barbiturates that induce burst suppression, high doses of corticosteroids, plasmapheresis, immunoglobulins, propofol, lidocaine, ketamine, inhaled desflurane, ketogenic diet, lacosamide, and therapeutic hypothermia were tried at different times in a period of 8 weeks, but all of them were ineffective...

Epilepsy is a neurological condition that affects more than 50 million individuals worldwide. It presents as unpredictable, temporary and recurrent seizures often having negative physical, psychological and social consequences. To inform disease prevention and management strategies, a comprehensive systematic review of the literature on risk factors for the onset and natural progression of epilepsy was conducted. Computerized bibliographic databases for systematic reviews, meta-analyses, observational studies and genetic association studies published between 1990 and 2013 describing etiological risk factors for epilepsy was searched...

OBJECTIVE: To describe and analyze the chronological evolution of the radiological findings in seven children with febrile infection-related epilepsy syndrome. METHODS: This is a retrospective study describing the radiological findings and evolution in seven children with febrile infection-related epilepsy syndrome who presented from 2009 to 2013. The children all fit the defined clinical criteria for febrile infection-related epilepsy syndrome; all had a history of normal psychomotor development who presented with acute-onset catastrophic partial status epilepticus associated with a febrile illness or unspecific infectious process...

BACKGROUND: Febrile seizures are the most common seizure disorder in childhood, associated with a significant rise in body temperature. However, post-infectious refractory afebrile form of seizures in previously healthy children is being increasingly recognized in around the world, which evolves into a chronic refractory form of epilepsy. The term 'Febrile infection-related epilepsy syndrome' (FIRES) has been proposed for these conditions and represents a refractory severe post-infectious epileptic condition in previously normal children...

An underlying immune basis is emerging in an increasing number of epileptic and encephalopathic syndromes. The immunopathological mechanisms may be categorized into antibody-mediated, T-cell cytotoxicity, and microglia-induced degeneration. The immune basis in Rasmussen syndrome is thought to be T-cell mediated. Antibodies to extracellular and intracellular epitopes are implicated in limbic and other encephalitides, characterized by seizures, movement disorder, sleep disorder, obtundation, psychosis, mutism, and other psychiatric symptoms...

To review the literature about febrile seizures and GEFS plus with special emphasis on management and outcome. Selected literature review. Febrile seizures are the most common convulsive event in humans, occurring in 2-6% of the population. The aetiology is complex with strong evidence for a heterogeneous genetic predisposition interacting with fever of any cause, with certain viral infections having a greater effect. A large amount of literature has established that febrile seizures have no long-term consequences on cognition or behaviour...

Autoimmunity is being increasingly recognized as a cause of neurologic presentations both inside and outside the intensive care unit (ICU) setting. Pediatric autoimmune neurologic diseases likely to be seen in the ICU include autoimmune encephalitidies such as N-Methyl-D-aspartate (NMDA) receptor encephalitis, central nervous system vasculitis, demyelinating disorders, and neurologic involvement of systemic autoimmune disorders. In addition, there are conditions of suspected autoimmune etiology such as febrile infection-related epilepsy syndrome (FIRES) and rapid-onset obesity, hypoventilation, hypothalamic dysfunction, and autonomic dysregulation (ROHHAD) syndrome that are rare, but when they do present, it is often to the ICU...

Febrile infection-related epilepsy syndrome (FIRES) is a newly recognized epileptic encephalopathy in which previously healthy school-aged children present with prolonged treatment-resistant status epilepticus (SE). Survivors are typically left with pharmacoresistant epilepsy and severe cognitive impairment. Various treatment regimens have been reported, all with limited success. The ketogenic diet (KD) is an alternative treatment of epilepsy and may be an appropriate choice for children with refractory SE...

The mechanisms of epileptogenesis in pediatric epileptic syndromes are diverse, and may involve disturbances of neurodevelopmental trajectories, synaptic homeostasis, and cortical connectivity, which may occur during brain development, early infancy, or childhood. Although genetic or structural/metabolic factors are frequently associated with age-specific epileptic syndromes, such as infantile spasms and West syndrome, other syndromes may be determined by the effect of immunopathogenic mechanisms or energy-dependent processes in response to environmental challenges, such as infections or fever in normally-developed children during early or late childhood...

UNLABELLED: Febrile seizures (FS) are a benign epileptic manifestation of infancy occurring between 3 months and 5 years of age and affecting an estimated 2-5 % of children. They have usually no important negative effects on motor and cognitive development. Simple FS (generalized seizures, lasting less than 10 min and single episodes during the same febrile event) have a benign prognosis in almost all cases and do not require an extensive diagnostic workup. In complex FS (focal semiology and lasting more than 10 min, more than one episode during the same febrile event), a more detailed clinical, electroencephalographic, laboratory, and neuroimaging evaluation is necessary because of a higher percentage of underlying detectable causes and a mildly higher risk for later development of epilepsy...

Idiopathic hemiconvulsion hemiplegia and epilepsy syndrome (IHHE) and febrile infection-related epilepsy syndrome (FIRES) are rare epileptic syndromes characterized by the occurrence of status epilepticus in a previously healthy child during or closely after a febrile episode. In both syndromes, there is no evidence of central nervous system infection (encephalitis) and the etiology remains unclear. Treatment is disappointing, particularly in FIRES, except for a response to ketogenic diet (KD) in half of patients...

Febrile infection-related epilepsy syndrome (FIRES) is a severe epileptic syndrome that manifests with refractory seizures or status epilepticus in previously healthy children after banal febrile illness. The neuroimaging findings in the acute phase of FIRES are nonspecific or normal. We report the case of a 7-year-old boy with FIRES who presented with a reversible lesion in the splenium of the corpus callosum on brain magnetic resonance imaging (MRI). The patient developed clusters of clonic seizures with a deviation of the eyes after a 3-day history of fever...

Febrile infection-related epilepsy syndrome (FIRES) is a catastrophic and usually refractory epilepsy syndrome that occurs after a febrile illness in previously normal children. The pathogenesis of the syndrome is unknown, and the diagnosis is typically made by exclusion after an exhaustive negative workup for central nervous system infections and autoimmune or metabolic disorders. Magnetic resonance imaging of patients with this condition has previously shown hippocampal abnormalities, typically found several months or longer after initial seizures...
