Febrile infection-related epilepsy syndrome (FIRES) is a catastrophic epilepsy syndrome which is characterized by acute onset of refractory status epilepticus following a febrile infection occurring in previously normal children. Despite the various treatment options that have been tried, exact treatment strategy is still undetermined. This is the first pediatric case of FIRES from Turkey which was successfully treated with intravenous immunoglobulin (IVIG).

A previously healthy 8-year-old boy was referred to our hospital with a pre-diagnosis of status epilepticus and encephalitis. He presented with acute onset of convulsions and unconsciousness following fever and malaise lasting 7 days. On physical examination Glasgow coma scale was 12, his pupils were miotic. He had cafe–au-lait spots on his body. His fundus examination, cerebrospinal fluid findings and cranial magnetic resonance imaging did not reveal any abnormality. Results of comprehensive search for metabolic, toxicological, infectious and autoimmune etiologies were all negative. Generalized slowing was seen on the electroencephalography (EEG) of the patient indicating possible encephalopathy. The patient developed convulsive status epilepticus and was intubated on day 5. His seizures were controlled by continuous infusion of midazolam, thiopental and used for 4 days. Phenytoin, levetiracetam, topiramate were used simultaneously. IVIG was administered as an immunomodulator for refractory seizures on day-9. The patient was extubated on day 11. The diagnosis was made after a comprehensive negative search for central nervous system infection, autoimmune and metabolic diseases. At follow up it was learnt that he had had only two seizures in two years. Status epilepticus did not recur.

Clinicians should keep in mind FIRES which is a diagnosis of exclusion especially in refractory status epilepticus. IVIG treatment could have a benefit in these patients. Keywords : child, febrile, infection, epilepsy, syndrome, intravenous immunoglobulin
