A Comparison Between Serum Selenium Level in Febrile Children with or Without Seizure.

The role of trace elements in febrile seizure (FS) was considered recently. The present study was performed evaluating the serum level of selenium in febrile children aged 6-60 months with and without seizure. A cross-sectional study was performed in Mashhad University of Medical Sciences, Mashhad, Iran. Sixty patients aged 6-60 months including 30 children with FS and 30 febrile children without seizure were included. Blood sample was taken, and the serum level of selenium was measured. Data was analyzed using SPSS software. Sixteen patients in FS group (53.3%) and 10 patients in febrile group (33.3%) were males with an average age of 25.21 ± 15.91 and 26.47 ± 17.61 months, respectively. There was no significant difference between groups in age and sex (p = 0.77 and p = 0.19, respectively). The serum level of selenium was 87.34 ± 8.23 and 89.63 ± 9.83 µg/L in FS and febrile groups, respectively. Difference was not significant (p = 0.33). In children aged less than 1 year, the serum level of selenium in FS and febrile group was 83.32 ± 6.2 µg/L and 82.55 ± 8.32 µg/L, respectively. Difference was not significant (p = 0.87). In children aged more than 1 year, the serum level of selenium in FS significantly was lower compared to febrile group (87.96 ± 8.42 µg/L and 93.17 ± 8.66 µg/L, respectively, p = 0.04). The serum level of selenium was lower in children aged more than 1 year with febrile seizure compared to febrile ones.
