Abstract:

Objective To evaluate the therapeutic effects of ketogenic diet (KD) combined with perampanel (PER) on sleep-related spike-and-wave activity index (SWI), serum levels of central nervous system-specific protein S-100β and intellectual development in children diagnosed with epileptic encephalopathy with sleep-related spike-and-wave activation (EE-SWAS). Methods A prospective randomized controlled trial was conducted involving 99 children with EE-SWAS, and they were randomly assigned to the control group (n = 49, receiving PER monotherapy) and the experimental group (n = 50, receiving KD combined with PER). After six months of treatment, clinical efficacy, SWI, serum biomarkers including S-100β, neuron-specific enolase (NSE) and brain-derived neurotrophic factor (BDNF) were assessed and compared between groups. Cognitive function was evaluated using the Wechsler Intelligence Scale for Children—Fifth Edition (WISC-V). Adverse events were systematically monitored throughout the study period. Results After treatment, SWI, S-100β and NSE levels were significant reduced in both groups, and BDNF level and WISC-V scores were higher compared to those of the control group (P<0.05). SWI, S-100β and NSE levels were lower in the experimental group than those of the control group, and BDNF level and WISC-V scores were higher in the control group (P<0.05). After treatment, the total effective rate was hiter in the experimental group (96.00%) than that in the control group (79.59%, P<0.05). There was no significant difference in the incidence of adverse events during the treatment period between the two groups (12.00% vs. 16.32%,P>0.05). Conclusion The combination of KD and PER demonstrates superior therapeutic efficacy in children with EE-SWAS, effectively reducing abnormal electroencephalographic activity, modulating key neurochemical markers, supporting cognitive development and exhibiting a favorable safety.
