Gras M, Bearden D, West J, Nabbout R. Efficacy of anti-seizure medications and alternative therapies (ketogenic diet, CBD, and quinidine) in KCNT1-related epilepsy: A systematic review. Epilepsia Open 2024; 9:1176-1191. [PMID: 39093319 PMCID: PMC11296097 DOI: 10.1002/epi4.12975] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/01/2024] [Revised: 04/26/2024] [Accepted: 04/29/2024] [Indexed: 08/04/2024] Open
Abstract
OBJECTIVE KCNT1-related epilepsies encompass three main phenotypes: (i) epilepsy of infancy with migrating focal seizures (EIMFS), (ii) autosomal dominant or sporadic sleep-related hypermotor epilepsy [(AD)SHE], and (iii) different types of developmental and epileptic encephalopathies (DEE). Many patients present with drug-resistant seizures and global developmental delays. In addition to conventional anti-seizure medications (ASM), multiple alternative therapies have been tested including the ketogenic diet (KD), cannabidiol (CBD-including Epidyolex © and other CBD derivatives) and quinidine (QUIN). We aimed to clarify the current state of the art concerning the benefits of those therapies administered to the three groups of patients. METHODS We performed a literature review on PubMed and EMBase with the keyword "KCNT1" and selected articles reporting qualitative and/or quantitative information on responses to these treatments. A treatment was considered beneficial if it improved seizure frequency and/or intensity and/or quality of life. Patients were grouped by phenotype. RESULTS A total of 43 studies including 197 patients were reviewed. For EIMFS patients (32 studies, 135 patients), KD resulted in benefit in 62.5% (25/40), all types of CBD resulted in benefit in 50% (6/12), and QUIN resulted in benefit in 44.6% (25/56). For (AD)SHE patients (10 studies, 32 patients), we found only one report of treatment with KD, with no benefit noted. QUIN was trialed in 8 patients with no reported benefit. For DEE patients (10 studies, 30 patients), KD resulted in benefit for 4/7, CBD for 1/2, and QUIN for 6/9. In all groups, conventional ASM are rarely reported as beneficial (in 5%-25% of patients). SIGNIFICANCE Ketogenic diet, CBD, and QUIN treatments appear to be beneficial in a subset of patient with drug-resistant epilepsy. The KD and CBD are reasonable to trial in patients with KCNT1-related epilepsy. Further studies are needed to identify optimal treatment strategies and to establish predictive response factors. PLAIN LANGUAGE SUMMARY We performed an extensive review of scientific articles providing information about the therapeutic management of epilepsy in patients with epilepsy linked to a mutation in the KCNT1 gene. Conventional anti-seizure treatments were rarely reported to be beneficial. The ketogenic diet (a medical diet with very high fat, adequate protein and very low carbohydrate intake) and cannabidiol appeared to be useful, but larger studies are needed to reach a conclusion.

ILAE classification and definition of epilepsy syndromes with onset in neonates and infants: Position statement by the ILAE Task Force on Nosology and Definitions. Epilepsia 2022; 63:1349-1397. [PMID: 35503712 DOI: 10.1111/epi.17239] [Citation(s) in RCA: 270] [Impact Index Per Article: 135.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/23/2021] [Revised: 03/20/2022] [Accepted: 03/21/2022] [Indexed: 12/20/2022]
Abstract
The International League Against Epilepsy (ILAE) Task Force on Nosology and Definitions proposes a classification and definition of epilepsy syndromes in the neonate and infant with seizure onset up to 2 years of age. The incidence of epilepsy is high in this age group and epilepsy is frequently associated with significant comorbidities and mortality. The licensing of syndrome specific antiseizure medications following randomized controlled trials and the development of precision, gene-related therapies are two of the drivers defining the electroclinical phenotypes of syndromes with onset in infancy. The principal aim of this proposal, consistent with the 2017 ILAE Classification of the Epilepsies, is to support epilepsy diagnosis and emphasize the importance of classifying epilepsy in an individual both by syndrome and etiology. For each syndrome, we report epidemiology, clinical course, seizure types, electroencephalography (EEG), neuroimaging, genetics, and differential diagnosis. Syndromes are separated into self-limited syndromes, where there is likely to be spontaneous remission and developmental and epileptic encephalopathies, diseases where there is developmental impairment related to both the underlying etiology independent of epileptiform activity and the epileptic encephalopathy. The emerging class of etiology-specific epilepsy syndromes, where there is a specific etiology for the epilepsy that is associated with a clearly defined, relatively uniform, and distinct clinical phenotype in most affected individuals as well as consistent EEG, neuroimaging, and/or genetic correlates, is presented. The number of etiology-defined syndromes will continue to increase, and these newly described syndromes will in time be incorporated into this classification. The tables summarize mandatory features, cautionary alerts, and exclusionary features for the common syndromes. Guidance is given on the criteria for syndrome diagnosis in resource-limited regions where laboratory confirmation, including EEG, MRI, and genetic testing, might not be available.

The relationship between the characteristics of burst suppression pattern and different etiologies in epilepsy. Sci Rep 2021; 11:15903. [PMID: 34354098 PMCID: PMC8342459 DOI: 10.1038/s41598-021-95040-4] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/20/2021] [Accepted: 07/14/2021] [Indexed: 11/08/2022] Open
Abstract
To analyze the relationship between the characteristics of burst suppression (BS) pattern and different etiologies in epilepsy. Patients with a BS pattern who were younger than 6 months old were screened from our electroencephalogram (EEG) database. The synchronized and symmetric BS patterns under different etiologies in epilepsy were analyzed. A total of 32 patients had a BS pattern on EEG. The etiologies included genetic disorders (37.5%), cortical malformations (28.1%), inborn errors of metabolism (12.5%), and unknown (21.9%). Twenty-five patients were diagnosed with Ohtahara syndrome, one as early myoclonic encephalopathy, and one as epilepsy of infancy with migrating focal seizure. Five cases could not be classified into any epileptic syndrome. Asynchronous BS pattern was identified in 18 cases, of which 13 (72%) patients had genetic and/or metabolic etiologies. Synchronous BS pattern was identified in 14 cases, of which 8 (57%) patients had structural etiologies. Twenty-three patients had symmetric BS patterns, of which 15 (65%) patients had genetic etiologies. Nine patients had asymmetric BS patterns, of which 8 (89%) patients had structural etiologies. Patients with genetic epilepsies tended to have asynchronous and symmetric BS patterns, whereas those with structural epilepsies were more likely to have synchronous and asymmetric BS patterns.

Abstract
OBJECTIVE Epilepsy of infancy with migrating focal seizures (EIMFS) is a rare and severe developmental epileptic encephalopathy. The aim of this study was to improve our understanding of EIMFS by using phenotype-genotype correlation. METHODS We recruited, performed clinical genetic testing, and summarized the clinical features and genetic characteristics in five patients with EIMFS in China. RESULTS The five recruited patients included 2 males and 3 females. The median age of seizure onset was 2 months (range, day 3 to 3 months). All patients exhibited the characteristics of clinically migrating focal motor (tonic or clonic) seizures. Typical migrating ictal electrical patterns were found in 1 patient; the remaining four patients presented with overlapping seizures with different areas of ictal onset in differing hemispheres. All the patients had the associated variants, including KCNT1, SCN1A, SCN2A, TBC1D24 and ALG1. All patients received two or more antiseizure medications, and 1 patient became seizure-free, 1 reported >75 % seizure reduction, 2 reported >50 % seizure reduction, and 1 patient showed no improvement. Varying degrees of psychomotor developmental delays were observed in all patients. CONCLUSIONS The course of EIMFS could be related to the type of gene variant present, and different genes may have specific clinical features. Larger cohorts are required to elucidate such potential phenotype-genotype correlations.

Abstract
Data on KCNT1 epilepsy of infancy with migrating focal seizures are heterogeneous and incomplete. Kuchenbuch et al. refine the syndrome phenotype, showing a three-step temporal sequence, poor prognosis with acquired microcephaly, high prevalence of extra-neurological manifestations and early mortality, particularly due to SUDEP. Refining the electro-clinical spectrum should facilitate early diagnosis.

Abstract
PURPOSE In rare cases, patients with epilepsy of infancy withmigrating focal seizures (EIMFS) exhibit suppression-burst (SB) patterns on electroencephalography (EEG), similar to the findings observed in patients with Ohtahara syndrome and early myoclonic encephalopathy. In this report, we discuss six cases of EIMFS in which patients exhibited two types of SB patterns. METHODS We evaluated six patients with EIMFS who had been admitted to the NHO Shizuoka Institute of Epilepsy and Neurological Disorders between 2011 and 2018. We retrospectively examined clinical characteristics and EEG findings for each patient. In all patients, the first EEG was performed within 1 month after seizure onset. Afterwards, EEG examinations were performed at irregular intervals (ranging from 1 to 5 months). RESULTS Age at seizure onset ranged from 2 days to 3 months. SB was first detected within 1 month of age in two patients, and within the range of 3-14 months in the remaining four patients. Among the latter four patients, SB patterns persisted at the final EEG recording in three patients (34-54 months). In all patients, SB patterns were observed during sleep only. Interhemispheric asynchrony in SB was observed in the two patients who exhibited SB within 1 month of age, while synchronous SB patterns were observed in the remaining four patients. CONCLUSIONS Our findings indicate that EIMFS may be associated with two types of SB patterns (early-onset and late-onset), which can be distinguished based on the stage of emergence and level of synchrony.
