Recurrence Risk of Febrile Seizures in Children
Introduction: Febrile seizure is a common paediatric problem. Identifying children with febrile seizure who are at risk for recurrence is important so that special attention can be given to them. The objective of this study was to identify the risk factors for recurrence of febrile seizures in children.
Materials and Methods: This was a prospective cohort study done at Kathmandu Medical College and Teaching Hospital, Kathmandu, Nepal. This study is a continuation of a previous study which looked at the leucocytosis in peripheral blood of children with febrile seizure. A detailed history including the risk factors for febrile seizure recurrence was obtained from the caregiver during follow up on subsequent days after discharge of children from the hospital who were previously admitted for febrile seizure. All children with febrile seizure belonging to age group of 6 months to 6 years were included in the study. Those with afebrile seizures or on anticonvulsants and those who refused to give consent were excluded. Each child was also examined and investigated for the cause of fever.
Results: A total of 115 children with febrile seizure admitted for febrile seizure during the study period and all of them were followed up at outpatient department. Males accounted 62% and females 38%. Simple Febrile Seizures were seen in 80% of the cases and complex febrile seizures were seen in 20%. Out of all the cases 68(59%) had symptoms of viral prodrome. 59(51%) had recurrent febrile seizure. Low temperature at onset of Febrile Seizure (p=0.001), short duration of fever before onset of Febrile Seizure (0.026) and atypical Febrile Seizure (p=0.022) were the risk factors for recurrent febrile seizure.
Conclusion: Febrile Seizure is a common paediatric problem commonly seen in males. Almost half of children with Febrile Seizure are at risk for recurrence in later date. The risk factors for these recurrences are modest rise in body temperature at the onset of febrile seizure, onset of seizure within 12 hours of fever and atypical presentation.
