The study conducted a long-term follow-up of epilepsy patients, finding that although some patients showed improvement after discharge from the intensive care unit, the severity of the disease remained high during follow-up. Most patients experienced varying degrees of impairment in functional outcomes, leading to a decline in independence and cognitive function.
Background and purpose Febrile-infection-related epilepsy syndrome (FIRES) is an exceedingly rare and devastating subtype of new-onset refractory status epilepticus, which causes refractory epilepsy and permanent neurocognitive impairment. Methods This was a long-term follow-up of adult FIRES survivors treated between 2005 and 2018 as part of the EpiCARE initiative, a European Reference Network for rare and complex epilepsies. Clinical, electroencephalography, imaging and functional outcome measures are described using the Scores of Independence for Neurologic and Geriatric Rehabilitation, the modified Rankin Scale and the Global Assessment of Severity of Epilepsy Scale. Results Six patients with refractory epilepsy following FIRES were evaluated. Despite general improvement after intensive care unit discharge, disease severity was still high at follow-up in all patients. The functional outcome, as assessed by the modified Rankin Scale, was moderately impaired in 2/6 patients. In contrast, the Scores of Independence for Neurologic and Geriatric Rehabilitation indicated a loss of independence in 5/6, serious problems in memory and planning/problem-solving in 4/6 and serious attentional problems in 3/6 patients. Conclusions Febrile-infection-related epilepsy syndrome survivors may regain vital functions and mobility but experience a significant loss of independence and participation due to recurring seizures, structural brain damage and neurocognitive decline. Minimization of disastrous outcomes through the systematic evaluation of rescue therapies within a network of specialized centres is crucial.
