AimFebrile convulsion (FC) is a common cause of seizure in young children, with an excellent prognosis. In addition to genetic predisposition, FCs are generally thought to be induced by elemental changes such as iron deficiency. Regarding the high prevalence of febrile seizure and iron deficiency anemia in children, the aim was to investigate the role of iron deficiency anemia in FC patients.MethodsThis case-control study was performed in 500 children with febrile seizures (case) and 500 febrile children without seizures (control), referred to Mofid hospital in Tehran during one year (Nov 2009-Nov 2010). All children were aged between 6-60 months. The groups were matched in age and gender and use of supplemental iron. Laboratory tests consisted of Complete Blood Count (CBC). Serum iron, plasma ferritin and Total Iron Binding Capacity (TIBC) analyses were done in each patient.ResultsThe patients and controls were 26.49+12.65 and 26.84+11.70 months of mean age, respectively. The amount of Hb, Hct, MCV, MCH, MCHC, RBC count, serum iron and plasma ferritin were significantly higher and TIBC was significantly lower among the cases with febrile convulsion than the controls. The incidence of iron deficiency anemia was significantly higher in controls compared with the cases (p less than 0.016). The mean of temperature peak on admission was significantly higher in the febrile convulsion group than controls.ConclusionThe results of this study suggest that the risk of febrile seizure occurrence in anemic children is less common as compared to non-anemic ones.
