Background: Febrile seizure (FS) is a common neurological condition in children and affects 2-5% of cases of fever. FS occurs with temperature >38 °C without symptoms of central nervous system infection, severe electrolyte imbalance, or clear cause.
Methods: From June 2018 to December 2019, 65 children with FS, and 60 children with acute upper respiratory tract infections without seizures who were admitted to the pediatric department, and 60 healthy children as the control group were selected for the study. The serum iron (SI), serum calcium (SC), interleukin (IL)-6, IL-10 and procalcitonin (PCT) levels in the two groups of children were detected. The FS group was further divided into simple FS (SFS) and complex FS (CFS).
Results: The duration of fever in the FS group was significantly longer than in the control group (P<0.05). The SC and SI levels of the FS group were significantly lower than those in the control group (P<0.05). The SC and SI levels of the CFS group were also lower than those of the SFS group (P<0.05), and the IL-6 levels of the CFS group were significantly higher than in the SFS group (P<0.05).
Conclusions: A decrease in the levels of SI, and SC and an increase of IL-6 were closely related to the occurrence of FS, suggesting that clinical attention should be paid to monitoring changes of SI, SC and IL-6 levels in children with FS. As the levels of SI and SC decrease, the frequency of possible seizures may increase. Care should be taken to correct electrolyte disorders in time.
