Evaluation of Serum Zinc Levels in Children of 6 Months to 5 Years of Age Diagnosed with Simple Febrile Seizures

Background: Febrile seizures are defined as seizures associated with a febrile illness that developed without central nervous system infection or acute electrolyte imbalance, intoxication, trauma, and metabolic disorder in children aged 1 month to 5 years without previous afebrile seizures. Various studies show a relationship between zinc levels and febrile seizures. Objectives: The purpose of this study was to examine the relationship between serum zinc levels and febrile seizures. Methods: This prospective, cross-sectional, and descriptive study was conducted from 04/10/2021 to 04/02/2022. A total of 85 children aged 6 months to 5 years admitted to the pediatric emergency service of the Republic of Turkey Ministry of Health Cemil Taşcıoğlu City Hospital were included in the study. The patients who met the inclusion criteria and whose consent was obtained were included in the study. Complex and febrile status patients were not included in the study due to the small number of patients. The cases included in the study were divided into 2 groups of patients and healthy controls. The patients with fever were divided into 2 groups, including those with and without febrile seizures. The levels of zinc and complete blood count parameters were measured in the blood samples taken from all the patients. IBM SPSS 22 package software was used for the statistical examination of the data. Results: When the cases included in this study were divided according to gender, 33 (38.8%) and 52 (61.2%) patients were female and male, respectively. The mean age of the cases was 29.2 ± 15.9 months (range: 6 - 60). Of the 85 participating cases, 30 patients had febrile seizures, 30 were only febrile patients, and 25 were healthy controls. When zinc levels were compared between the groups, the plasma zinc levels of the febrile seizures and febrile groups were observed to be lower than the healthy control group (P < 0.05). Conclusions: In this study, the group consisting of patients with febrile seizures and the groups of patients who had a fever but did not have febrile seizures during the study had reduced serum zinc levels than the control group consisting of healthy patients without fever.
