Abstract

Objective  

Febrile convulsion (FC) is a common cause of seizure in young children, with an excellent prognosis. In addition to genetic predisposition and infections,FCs are generally thought to be induced by metabolic and elemental changes during fever such as Zinc (Zn) deficiency. Regarding the high prevalence of febrile convulsions and the role of Zn deficiency, we investigated the role of Zn in FC patients in Isfahan, Iran.  

Materials and Methods  

In a controlled cross sectional study, 90 patients aged 9 months to 5 years were studied in a period of 12 months. They were assigned to three groups. Thirty patients were included in the Febrile Seizure group, thirty febrile children without convulsion or previous history of convulsion were included in the febrile group and thirty afebrile healthy ones were enrolled as controls. Venous blood was obtained and Zn concentration in serum was measured using Graphite Furnance Atomic Absorbance Spectrophotometering (GF-AAS).  

Results  

Patients and the control groups had no difference in either mean age or sex distribution. No significant relationship was observed between serum Zn level and age or sex among patients in the FC group and two other control groups.  

Conclusion  

Our findings showed that Zinc level was significantly lower in the febrile seizure group compared to two other groups. We tried to categorize various conditions in a more practical form. Also, Zinc is in close relationship with socioeconomic level of the individuals which was well considered in the current survey.
