ABSTRACT
BACKGROUND: As the Omicron variant of the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) emerges, the neurological manifestations correlated with this epidemic have garnered increasing attention. This study was primarily intended to compare seizures in febrile children with and without SARS-CoV-2 infection and to conduct short-term follow-up of the SARS-CoV-2-infected patients. METHODS: Retrospective analysis of patients admitted to the Children's Hospital of Chongqing Medical University for fever and seizures between October 1 and December 30, 2022. Based on the results of SARS-CoV-2 Reverse Transcription-Polymerase Chain Reaction(RT-PCR) at the time of admission, the patients were divided into a Coronavirus disease 2019(COVID-19) positive group and a COVID-19 negative group. Aside from that, we followed up COVID-19-positive patients for 3 months after their discharge from the hospital. The follow-up included monitoring for post-discharge seizures. RESULTS: Compared with the COVID-19-negative group, the COVID-19-positive group had a higher proportion of seizure duration ≥ 15 min(18.7%VS5.1%;P = 0.001), seizure ≥ 2 time(54.4%VS41.0%; P = 0.024), status epilepticus(15.4%VS5.1%; P = 0.005), and Electroencephalogram (EEG) abnormalities(29.4%VS13.6%; P = 0.016). Among the 161 individuals under follow-up, 21 (13.0%)experienced a recurrence of seizures. CONCLUSIONS: Although the incidence of seizure duration ≥ 15 min, number of seizures ≥ 2 time, and status epilepticus was higher in the COVID-19-positive group, the majority of patients had a favorable prognosis. Nonetheless, patients with COVID-19 who present with seizures and persistent impaired consciousness need to be alerted to serious neurological disorders such as acute necrotizing encephalopathy. Owing to the consideration that some patients may experience a recurrence of seizures within a short period of time, it is paramount to provide guardians with education about the emergency management of seizures and to follow up with patients over time.
