| Popis: | Febrile seizures are the most common seizures in children. Children with complex febrile seizures have a higher risk of subsequent epilepsy compared with children with simple febrile seizures. Multiple risks factors for epilepsy, including focal status epilepticus, family history of epilepsy, neurodevelopmental abnormalities and abnormal electroencephalogram findings, have been found with inconsistent results. The aim of this study is to identify risk factors for developing epilepsy in children with complex febrile seizures.The study included 248 children aged 3-72-months, diagnosed with complex febrile seizures at Chiang Mai University Hospital. Demographic data, seizure characteristics, electroencephalogram and neuroimaging findings were identified, and assessed to establish whether they were risk factors for subsequent epilepsy.Fifty-five patients (22.1%) had subsequent epilepsy. Using Cox regression-survival analysis, factors associated with epilepsy were prolonged seizures15 min (P = 0.006; Hazard Ratio (HR): 2.475; 95% Confidence Interval (CI): 1.294-4.735), developmental delay (P = 0.019; HR: 4.476; 95% CI: 2.280-15.646), epileptiform discharges on electroencephalogram (P = 0.023; HR: 1.391; 95%CI: 1.174-1.876), and abnormal neuroimaging (computed tomography or magnetic resonance imaging; P = 0.028; HR: 1.355; 95% CI: 1.034-1.776). Age at onset, peak febrile temperature, duration between the onset of fever and the occurrence of seizure, recurrent seizures within 24 h, focal seizures, abnormal neurological exams and family history of febrile seizure or epilepsy were not associated with increased risk of subsequent epilepsy in this study.Risk factors associated with increased risk of epilepsy in children with complex febrile seizures are prolonged seizures or febrile status epilepticus, developmental delay, electroencephalogram epileptiform discharges, and abnormal neuroimaging. Their presence would merit close clinical monitoring. |
