AI Article Synopsis
- The study investigated the role of interleukin-4 (IL-4) gene polymorphisms in patients with febrile seizures, expanding on limited previous research focused mostly on the Japanese population.
- The results showed a significant increase in the IL4-590/C allele frequency among patients compared to controls, while certain genotypes (IL-4 (-590) TC and IL-4 (-33) TC) were found to be less common in the patient group.
- The findings suggest that specific IL4 gene variations may increase susceptibility to febrile seizures in the Iranian population, indicating a need for further research in diverse ethnic backgrounds.
Article Abstract
As of importance of interleukin-4 (IL-4) in inhibiting the production of proinflammatory cytokines, the IL4 gene polymorphisms were investigated in patients with febrile seizure. This association has not been investigated yet, except 1 study which has been done in Japanese population. Eighty-two patients with febrile seizure were enrolled in this study, compared with 139 controls. The allele and genotype frequency of 3 single-nucleotide polymorphisms of IL4 gene were determined. Frequency of the IL4-590/C allele in the patient group was significantly higher than in the control group (P < .0001). Frequency of the following genotypes was significantly lower in patients compared to controls: IL-4 (-590) TC (P = .0001) and IL-4 (-33) TC (P = .001). The most frequent IL-4 haplotype in the patient group was TCC (P = .00) haplotype. In contrast, frequencies of GCC (P = .01), TTT (P = .009), and TTC (P = .0007) haplotypes were significantly lower in febrile seizure patients. Certain alleles, genotypes, and haplotypes in the IL4 gene were overrepresented in Iranian patients with febrile seizure, which could predispose individuals to this disease, and further investigations in other ethnicities are required.

Febrile infection-related epilepsy syndrome (FIRES) is a rare clinical presentation of refractory status epilepticus following a febrile infection. This study analyzes data from the NORSE/FIRES Family Registry, an international web-based registry available in six languages with data entered by patients, families, and clinicians to explore clinical presentations, survivorship, and long-term outcomes in adult and pediatric FIRES patients. We characterize and examine differences in demographics, prodromal symptoms, seizure frequency, anti-seizure medications (ASMs), quality of life, cognition, mood, and anxiety in adults vs pediatric populations with FIRES.

Rationale: PCDH19-related epilepsy manifested various clinical features, including febrile epilepsy, with or without intellectual disability, and psych-behavioral disorders. However, there are few studies demonstrating abdominal pain as the first symptom.
Patient Concerns: A 3-year-old Chinese girl presented with clustered seizures of fever sensitivity accompanied by abdominal pain.
An analysis on role of iron deficiency in febrile seizure among children in 6 months to 5 years: A case-control study.

Department of Paediatrics, Sri Ramachandra Institute of Higher Education and Research, Tamil Nadu, India.
Background For The Study: This study looks into the relationship between febrile seizures in children between the ages of 6 months to 5 years who suffer from iron insufficiency. Febrile seizures, which are common in early life, are associated with abrupt temperature increases, and iron deficiency impacts neurological development in young infants. Understanding this relationship would lead to interventions that mitigate febrile seizure impact.
