Etiology of Non-Traumatic Seizures in Children Admitted to PICU: An Eight-Year Retrospective Study.
2020
Purpose Seizure is a serious neurological symptom in the pediatric intensive care unit (PICU), yet data on etiologies of non-traumatic childhood seizures in China are scarce. We aimed to investigate the etiological trends of seizures in children admitted to the PICU in our tertiary center. Patients and Methods We performed a retrospective analysis of all patients (aged 29 days to 14 years) with non-traumatic seizures, admitted to the PICU of Xiangya Hospital from 2010 to 2017. Etiological analysis was performed to compare data between 2010-2013 and 2014-2017. Results The study included 318 patients (male: female = 1.27:1) with mean age of 5.4 ± 4.0 years. The most frequent causes observed were CNS infections (109/318, 34.3%), unknown reason epilepsy (96/318, 30.2%), and immune (56/318, 17.6%). Comparison of the 2010-2013 and 2014-2017 periods revealed a significant decrease in the percentage of CNS infections [48.8% (59/121) vs 25.4% (50/197), p < 0.001] and a significant increase in the incidence of unknown reason epilepsy [(24/121, 19.8%) vs (72/197, 36.5%), p < 0.001] and immune causes [(12/121, 9.9%) vs (44/197, 22.3%), p = 0.005]. Conclusion CNS infections were the most common cause of seizures during 2010-2013, while non-infectious diseases such as epilepsy and immune disorders represented the leading causes during 2014-2017. Continuous improvement in medical technology and understanding of disease patterns would greatly improve early diagnosis and therapeutic management of such conditions.
