Risk factor analysis of benign childhood epilepsy with centrotemporal spikes complicated by electrical status epilepticus in sleep / 中华实用儿科临床杂志

ABSTRACT

Objective To evaluate the risk factors for benign childhood epilepsy with centrotemporal spikes (BECT) complicated by electrical status epilepticus in sleep(ESES).Methods From January 2013 to January 2017,a total of 80 children diagnosed as BECT in pediatric neurology outpatient department of Provincial Clinical Medical College Affiliated to Fujian Medical University were enrolled.According to whether there was an attack of ESES or not,patients were divided into ESES group(38 cases) and non-ESES group(42 cases).In order to elucidate risk factors for BECT complicated by ESES,clinical data including age,gender,first seizure age,seizure frequency before treatment,types of seizure,therapeutic drug,recurrence of seizure after treatment,febrile seizure,status at birth,family history,brain MRI,discharge quantity,discharge location,and intelligence score were investigated by multivariate Logistic regression analysis.Results Compared with non-ESES patients,ESES patients were more likely to have recurrence of epilepsy after treatment (68.4％ vs 26.2％,P ＜ 0.001),and had worse intellectual development (＜ 90 scores;73.7％ vs 38.1％,P =0.001);while electroencephalogram showed more discharge in anterior location (47.4％ vs 21.4％,P =0.014) and bilateral distribution of brain (52.6％ vs 26.2％,P =0.015).However,the multivariate Logistic regression analysis showed that only recurrence of seizure after treatment was the risk factor for ESES in BECT patients(P=0.008,OR=4.039,95％CI:1.429-11.418).Conclusion Recurrence of seizure after treatment of BECT was a high risk factor for ESES.Controlling seizure and reducing ESES phenomenon could be beneficial to alleviate the intellectual impairment of patients with BECT.
