Serum Zinc Level in Children with Febrile Seizure

Objectives Febrile seizure (FS) is the most common type of seizure in children. FS is a genetic age-limited seizure, which only occurs with febrile illness. Today, it is known that genetic factors play a major role in the occurrence of FS. Nevertheless, some trace elements, such as zinc, may play an important role in the occurrence of FS. In this study, we investigated the serum level of zinc in patients with FS and febrile children without seizure (control group). Materials &Methods This prospective case-control study was conducted on 41 patients with simple and complex FS as the case group and 41 febrile children without seizure as the age- and sex-matched control group. The participants were admitted to Best Hospital of Hamedan, Iran between January 2013 and January 2014 . The children’s age ranged from six months to five years. Serum zinc levels were measured by atomic absorption spectroscopy in these groups. Results The mean serum zinc levels were 70.41±20.46 and 92.73±17.62 mcg/ dL in the case and control groups, respectively (P=0.001). The results showed that the serum zinc level in children with FS was significantly lower than that of the control group. Conclusion Based on the present results, serum zinc level was lower in children with febrile seizure. However, further basic research is needed to examine the efficacy of zinc supplements in the prevention of FS.
