  • Preliminary investigation on inducing factors of epileptic seizures

    ObjectiveTo explore and clarify the relationship between epileptic seizure and inducing factors. Avoid inducing factors and reduce epileptic seizure, so as to improve the quality of life in patients with epilepsy.MethodsClinical data of 604 patients diagnosed with epilepsy in Xijing Hospital of Air Force Military Medical University from January 2018 to January 2019 were collected. The clinical data of patients with epilepsy were followed up 6 months.ResultsAmong the 604 patients, 318 (52.6%) were seizure-free in the last 6 months, 286 (47.4%) had seizures. 169 (59.1%) had seizures with at least one inducing factor. Common inducing factors: 123 cases of sleep disorder (72.8%), 114 cases of emotion changes (67.5%), 87 cases of irregular medication (51.5%), 97 cases of diet related (57.4%), 33 cases of menstruation and pregnancy (19.5%), etc. Using the χ2 test, seizures with age, gender differences had no statistical significance (P > 0.05), but seizure type was statistically different between inducing factors. In generalized seizures, tonic-clonic seizures associated with sleep deprivation (χ2= 0.189), absence seizures and anger (χ2= 0.237), pressure (χ2= 0.203), irregular life (χ2= 0.214). In the focal seizures, focal motor seizures was correlated with coffee consumption (χ2=0.145), focal sensory seizures with cold (χ2=0.235), electronic equipment use (χ2 =0.153), satiety (χ2 =0.257). Complex partial seizures was correlated with anger (χ2 =0.229), stress (χ2 =0.187), and cold (χ2 =0.198). The secondarily generalized seizures was correlated with drug missing (χ2 =0.231), sleep deprivation (χ2 =0.158), stress (χ2 =0.161), cold (χ2 =0.263), satiety (χ2 =0.182). Among the inducing factors, sleep deprivation was correlated with anger (χ2 =0.167), fatigue (χ2 =0.283), and stress (χ2 =0.230).ConclusionsEpileptic seizure were usually induced by a variety of factors. Generalized seizures were associated with sleep disorders, emotional changes, stress, irregular life, etc. While focal seizures were associated with stress, emotional changes, sleep disorders, cold, satiety, etc. An analysis of the triggers found that sleep deprivation was associated with anger, fatigue, and stress. Therefore, to clarify the inducing factors of epileptic seizure, avoid the inducing factors as much as possible, reduce the harm caused by seizures, and improve the quality of life of patients.

  • Value of long term videoelectroencephalography to instruct discontinuation of anti-epileptic drugs in patients with epilepsy

    ObjectiveTo explore the prognostic value of normal 24 hour video electroencephalography (VEEG) with different frequency on antiepileptic drugs (AEDs) withdrawal in cryptogenic epilepsy patients with three years seizure-free. MethodsA retrospective study was conducted in the Neurology outpatient and the Epilepsy Center of Xi Jing Hospital. The subject who had been seizure free more than 3 years were divided into continual normal twice group and once group according to the nomal frequence of 24 hour VEEG before discontinuation from January 2013 to December 2014, and then followed up to replase or to December 2015. The recurrence and cumulative recurrence rate of the two group after withdrawal AEDs were compared with chi-square or Fisher's exact test and Kaplan-Meier survival curve. A Cox proportional hazard model was used for multivariate analysis to identify the risk factors for seizure recurrence after univariate analysis. P value < 0.05 was considered significant, and all P values were two-tailed. Results95 epilepsy patients with cause unknown between 9 to 45 years old were recruited (63 in normal twice group and 32 in normal once group). The cumulated recurrence rates in continual two normal VEEG group vs one normal VEEG group were 4.8% vs 21.9% (P=0.028), 4.8% vs 25% (P=0.006) and 7.9% vs 25%(P=0.03) at 18 months, 24 months and endpoint following AEDs withdrawal and there was statistically difference between the two groups. Factors associated with increased risk were adolescent onset epilepsy (HR=2.404), history of withdrawal recurrence (HR=7.186) and abnormal VEEG (epileptic-form discharge) (HR=8.222) during or after withdrawal AEDs. The recurrence rate of each group in which abnormal VEEG vs unchanged VEEG during or after withdrawal AEDs was respectively 100% vs 4.92% (P=0.005), 80% vs 19.23%(P=0.009). ConclusionsContinual normal 24h VEEG twice before withdrawal AEDs had higher predicting value of seizure recurrence and it could guide physicians to make the withdrawal decision. Epileptic patients with adolescent onset epilepsy, history of seizure recurrence and abnormal VEEG (epileptic-form discharge) during or after withdrawal AEDs had high risk of replase, especially patients with the presence of VEEG abnormalities is associated with a high probability of seizures occurring. Discontinuate AEDs should be cautious.

  • 钙离子通道基因突变与癫痫

    引起癫痫发作的神经元阵发性同步异常放电与离子通道密切相关。因此,编码钙离子通道的基因成为癫痫病因的候选基因之一。现有的抗癫痫药物(AEDs)被证明其作用机制包括抑制钙通道活性。但目前还缺乏高选择性的钙离子通道阻断剂。了解不同发作类型的癫痫患者不同类型的钙离子通道编码基因突变,对理解癫痫的发病机制和今后的精准诊疗很有必要。现对钙离子通道及其分型、编码基因和已发现在癫痫患者中的突变作一综述。

  • 基于美国医学遗传学和基因组学会指南的基因检测报告解读

    随着精准医学的进一步开展,基因检测如雨后春笋般涌现,但检测报告质量却良莠不齐,亟待标准来规范。2015年,美国医学遗传学和基因组学会(American College of Medical Genetics and Genomics,ACMG)发布了关于测序技术在临床上应用的专业标准和指南,希望能为变异数据评级提供一个相对科学的标准。但2016年,Amendola等对比了美国9个中心实验室的测序解读结果,发现ACMG指南在具体实施过程中仍存在许多问题。所有实验室均通过该指南进行变异结果的判断,但其评级的相符率仅有34%。而对于ACMG指南的理解不同,是导致变异等级判断结论不一致的主要原因。作为临床医生,基因检测报告的解读是不可或缺的基本功,不仅要向实验室提供准确和完整的临床信息,也需要了解及掌握该指南,知道如何准确使用基因检测提供的证据来进行后续的诊断和治疗决策。现将基于ACMG指南,对3例癫痫患者基因检测报告进行解读,期望能更加形象具体地阐释该指南,使更多的临床医生更好的理解及运用指南。

  • DEPDC5 基因突变与癫痫

    mTOR 通路对于神经元活性和大脑发育有重要作用,其活性异常与癫痫发生有很大的相关性。DEPDC5 是 mTOR 通路的重要组成之一,其最早发现是家族性可变灶局灶性癫痫的主要病因,随着基因测序技术的发展,常染色体显性夜间额叶癫痫和家族性颞叶癫痫等家族性局灶性癫痫、Rolandic 癫痫以及散发性局灶性癫痫也被发现与 DEPDC5 突变相关。近期发现 DEPDC5 也可能与全面性癫痫相关。文献报道 DEPDC5 相关癫痫较为难治,部分患者伴有局灶性皮质发育不良、半侧巨脑畸形,但具体机制尚不明确。DEPDC5 突变可能增加癫痫意外猝死的发生率。体内实验发现 DEPDC5 的功能对于胚胎生长和大脑的发育具有重要的作用。体内外研究表明 DEPDC5 突变是通过增加 mTOR 通路的活性影响神经元形态及活性导致癫痫发生的。mTOR 通路抑制剂西罗莫司和依维莫司以及 DEPDC5 结构类似物或 DEPDC5 功能增效剂可能会改善 DEPDC5 相关癫痫的预后。此外,生酮饮食能降低 mTORC1 活性,可能对于 DEPDC5 相关癫痫的治疗有较好的效果。文章将总结 DEPDC5 相关癫痫的表型,分析其致病机制并探讨可能的有效治疗。

  • Clinical analysis of 20 patients with electrical status epilepticus during sleep

    ObjectiveTo improve the clinicians’ understanding and treatment level of electrical status epilepticus during sleep by analyzing the clinical data of patients with ESES retrospectively.MethodsWe collected 20 cases from 2018 to 2019 diagnosed in our hospital by clinical and 24-hour video EEG confirmed and analyzed the clinical manifestations, EEG features, seizure type, classification of epilepsy syndrome as well as the imaging findings.ResultsAmong the 20 patients, there were 12 males and 8 females, the mean age was (10.96±2.68) years old, and the first onset age was (8.90±1.93) years old. Epilepsy seizure as the first symptom is most common, the EEG showed a broad or localized sustained discharge, generalized tonic clonic seizure is the main form of seizure type in most patients, ECSWS is the most prominent in the epilepsy syndrome, for small lesion through MR can be found early.ConclusionMost patients have partial or generalized seizures, which have a range of cognitive impairment, mental decline or other issues. It is important to improve the cognitive function, behavior, neuropsychology of patients by long term video EEG monitoring in the early stage.

  • 局灶性皮质发育不良与癫痫:局灶性皮质发育不良分类及诊断更新

    局灶性皮质发育不良(Focal cortical dysplasia,FCD)属于皮质发育畸形的一种,由神经元移行或增殖障碍所导致,是儿童难治性癫痫最常见的原因。2011年国际抗癫痫联盟对FCD进行了详细的分类,被广泛应用于临床诊断和研究。但随着遗传学和病理学的快速发展,学者们对该分类不断进行修订,并建议增加遗传学诊断内容,以获得基因型-表型的综合诊断。此外FCD的表型以及诊治方案也在不断的更新,本文对FCD分类方案的更新以及其发病机制、病理表现、临床表型、诊断和治疗的进展作一综述,以期为FCD的规范诊疗提供一定参考。
