Trace elements in febrile seizure compared to febrile children admitted to an academic hospital in iran, 2011.

BACKGROUND AND AIM Pathogenesis of Febrile Convulsion (FC) is unknown but some elements and genetic predispositions have been considered in the top list. This case-control study was designed to compare some trace elements in paediatrics who were admitted with FC and those in febrile ones without seizure attacks at an academic hospital in northeast of Iran. MATERIAL AND METHODS This case-control study was done from June 2010 to July 2011 on 160 paediatrics (6-months to 5-years old) who were diagnosed with FC and on 160 age-matched febrile children as control group. Data on the age, gender, past history of fever and convulsion, age at the first episode of seizure and family history of FC were gathered by using a designed checklist. Complete Blood Count (CBC), serum iron, Total Iron Binding Capacity (TIBC), zinc, magnesium and calcium were tested after taking informed consents from the parents. Serum levels of trace elements were measured by a photometric method. Independent t-test or non-parametric Mann-Whitney test were used to compare means between two groups. RESULTS There were no significant differences between the cases and controls with regards to the gender or age. TIBC and magnesium were lower in FC, but calcium, iron and zinc were higher in FC as compared to those in the other group (not significant). CONCLUSIONS So, it could be said that deficiency of trace elements was not significantly related to febrile convulsion in our study and it seemed that these tests were not necessary in FC cases. But further investigations on other trace elements are needed.
