To define the risk and identify predictors of single and multiple recurrent febrile seizures.
Children (n=428) with first febrile seizures were prospectively identified and followed for 2 or more years.
Parents were interviewed soon after their children's first febrile seizure and were called every 3 months to ascertain recurrent febrile seizures.
Medical records of first and recurrent seizures were reviewed for additional information.
A total of 136 children (31.8%) experienced recurrent seizures : 73 (17.1%) had only 1 recurrence, 38 (8.9%) had 2 recurrences, and 25 (5.8%) had 3 or more recurrences.
Young age at onset, a history of febrile seizures in a first-degree relative, low degree of fever while in the emergency department, and a brief duration between the onset of fever and the initial seizure were strong independent predictors of recurrent febrile seizures.
With these 4 factors combined, it is possible to define groups of children having very high and very low probabilities of having any recurrences (>70% vs<20%), having 2 or more recurrences (>60% vs<10%), and having 3 or more recurrences (12% vs about 0%). In children who had at least 1 recurrence, age at the time of the first recurrence and a family history of epilepsy were predictors of subsequent recurrences.
In children who have had a first febrile seizure, recurrences are common. (...)
