RESUMO
Objective:To observe the clinical effect of Perampanel on the add-on therapy in children with drug-resistant epilepsy.Methods:Clinical data of children with drug-resistant epilepsy treated with add-on therapy of Perampanel in the Department of Pediatrics, Fujian Medical University Union Hospital from January to June 2020 were retrospectively analyzed, aiming to assess the therapeutic efficacy of Perampanel on the add-on therapy of drug-resistant epilepsy.The self-control effective rate of Perampanel before and after treatment were counted.Results:A total of 20 cases of 2-12 year-old children with drug-resistant epilepsy were collected, including 14 males and 6 females.Their mean age, age of onset and course of disease were (5.82±2.39) years, (3.41±1.96) years and (2.40±1.48) years, respectively.Among them, 1 case had simple partial seizures, 7 cases had complex partial seizures, 1 case had generalized seizures and 5 cases had epilepsy syndromes, there were 6 cases with undetermined seizure attack.After 3-month add-on therapy of Perampanel, 4 cases of children with drug-resistant epilepsy were seizure-free, 8 cases had the reduced frequency of seizure for 50% or more, 2 cases had the reduced duration of seizure, 1 case had the reduced severity of seizure, while 4 cases did not respond to perampanel and 1 case was aggravated.Based on the criteria of reduced frequency of seizure for more than 50%, the therapeutic efficacy of add-on therapy of Perampanel achieved 60% in children with drug-resistant epilepsy.Conclusions:The third generation of anti-seizure medication Perampanel can effectively reduce the frequency of seizure, especially in the elder children and those with certain epilepsy syndromes.
