Investigating the correlation between serum folic acid level and febrile seizures in children: A clinical study

Febrile seizure (FS) is a highly frequent presenting complaint in children. It is defined as a seizure that occurs in children between 6 to 60 months related to a fever of 38°C or more without any other explanatory causes of seizure such as evidence of central nervous system (CNS) infection or a previous seizure without fever. The aim od study is to evaluate mean folic acid serum levels in febrile children with or without seizures.

The mean folic acid serum levels and demographic data of 100 children aged 6 to 60 months, admitted to the Ghaem Hospital of Mashhad, Iran in 2018-2019, were collected, where the patients with febrile seizure were considered as the case group and the febrile ones without seizure as the control group. The inclusion criteria were children aged 6 to 60 months with febrile seizures who were admitted to the pediatric ward. The exclusion criteria were having a past medical history of seizure, meningitis, or encephalitis.

There were 49 febrile convulsive children (cases) and 51 febrile children without a seizure (controls). The mean serum folic acid level was 7.07 and 9.89 ng/ml for cases and controls respectively (P-value < 0.001).

Children with febrile seizures had significantly lower serum folic acid levels than febrile children without a seizure.
