  • 探寻预测急性卒中事件后发生癫痫的生物标记物

    血液生物标记物在卒中后癫痫中的作用尚未得到广泛研究。本研究旨在研究急性卒中的临床因素和生物标记物,并经过较长时间的观察分析它们与卒中癫痫发生的关系。对缺血性和出血性卒中的患者进行 14 个血液生物标记物的检测。用 Z-scores 对生物标记物进行规范化和标准化。同时还评估了卒中和癫痫相关变量:卒中严重程度(依据美国国立卫生研究院卒中量表 NIHSS 评分)、卒中类型和病因、从卒中到迟发性癫痫发作的时间以及癫痫发作类型。使用多因素 Cox 回归分析来确定与癫痫相关的独立的临床变量和生物标记物。从 1 115 例患者队列中纳入 895 例。平均年龄为(72.0±13.1)岁,其中有 57.8% 的患者为男性。51 例患者(5.7%)发展为迟发性癫痫,中位时间为 232 天[四分位数间距 IQR(86~491)]。NIHSS 分数≥8[P<0.001,HR=4.013,95%CI(2.123,7.586)]和早发性癫痫发作的病史[P<0.001,HR=4.038,95%CI(1.802,9.045)]是与癫痫发展风险相关的独立因素。预测癫痫的独立生物标记物有:高水平的内皮抑素>1.203[P=0.046,HR=4.300,95%CI(1.028,17.996)]、低水平的 70 kDa 热休克蛋白 8(Hsc70)<2.496[P=0.006,HR=3.795,95%CI(1.476,9.760)]和 S100B<1.364[P=0.001,HR=2.955,95%CI(1.534,5.491)]。当这些生物标记物共同存在时,癫痫风险上升至 17%。临床变量和血液生物标记物联合使用时,预测模型中受试者工作特性(ROC)曲线下的面积比单独一个存在时[68.9%,95%CI(60.3%,77.6%)]的面积大,为[74.3%,95%CI(65.2%,83.3%)]。S100B 和 Hsc70 的下降及内皮抑制素的升高可能有助于预测卒中后癫痫,这为临床危险因素提供了额外信息。此外,这些数据为癫痫发生假说过程提供了一定依据。

  • 肌阵挛性失张力癫痫的表型与遗传谱

    文章旨在描述一个大样本量的癫痫伴肌阵挛性失张力发作(MAE)患者神经发育损害程度,并确定其遗传学病因。采用标准化的神经心理学仪器对MAE患者的癫痫特征、智力残疾、自闭症谱系障碍和注意缺陷/多动障碍进行深入的表型分析。我们对癫痫和神经精神疾病的基因集进行外显子分析(全外显子测序),以确定遗传学病因。研究共分析了101例MAE患者(70%为男性)。发作年龄中位数为34月龄(范围6~72月龄)。主要发作类型为肌阵挛性失张力发作或失张力发作100%、全身强直阵挛性发作72%、肌阵挛性发作69%、失神性发作60%、强直性发作19%。研究观察到62%的患者有智力障碍,69%的患者适应行为评分极低。此外,24%表现出自闭症症状,37%表现出注意力缺陷/多动症状。85例患者中的12例(14%)发现了致病性变异,包括5例先前发表的患者。这些基因是SYNGAP1(n=3)、KIAA2022(n=2)、SLC6A1(n=2)以及KCNNA2、SCN2A、STX1B、KCNB1和MECP2(各n=1)。此外,研究还分别在3例患者中分别鉴定了1个新的候选基因—ASH1L、CHD4和SMARCA2。研究发现,MAE与明显的神经发育障碍有关。MAE具有遗传异质性,通过外显子分析在14%的队列中确定了致病的遗传病因。这些发现表明MAE是几种病因的表现,而不是一个离散的综合征实体。

  • Research progress on the influence and mechanism of SARS-CoV-2 infection on seizure

    At present, there are few studies on patients with epilepsy (PWE) and severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), and the results of many studies are inconsistent. SARS-CoV-2 may cause new seizures through a variety of mechanisms, and the susceptibility and mortality of PWE to SARS-CoV-2 remains controversial. During the SARS-CoV-2 pandemic, anxiety, depression and other psychological problems were common among epileptic patients. Clinicians providing telemedicine, telephone chat and video call can effectively reduce the risk of psychological disorders in PWE patients. At the same time, there are many interactions between antiepileptic drugs and various antiviral drugs, which should be carefully considered when using. Considering that the research results are few and many studies contradict each other, PWE and SARS-CoV-2 deserve further exploration in future studies.

  • The clinical features of congenital hyperinsulinemia presenting seizures as the initial symptoms

    ObjectiveTo analyze the clinical data of 5 cases of congenital hyperinsulinemia with sizures as the initial symptoms. MethodsRisk factors in perinatal period, clinical manifestation, laboratory examination, treatment and follow-up visits of 5 cases of congenital hyperinsulinemia with sizures as the initial symptoms were analyzed retrospectively, who were admitted to Department of Neurology of Jiangxi Children's Hospital from July 2012 to August 2016. Results5 children were all male. The onset time varied from 3 to 9 mouths old. All the cases presented seizures as the main clinical manifestations, persistent hypoglycemia, hyperinsulinemia, low free fatty acid and hypoketonemia. During follow-up, treatment with diazoxide and dietary therapy was effective in 3 cases, pure dietary therapy ineffective in 2 cases. 3 cases manifested as acute symptomic seizures, 2 cases as remote symptomic epilepsy. During follow-up, 1 cases showed normal intelligence, 3 cases developmental delay, and 1 case dropout. ConclusionMost of the infants with congenital hyperinsulinemia presented seizures as initial symptoms. Severe hypoglycemia and long duration would damage brain, and early management may significantly improve the prognosis. The early diagnosis can be made by measuring fasting blood glucose, insulin, free fatty acid and, plasma β-hydroxybutyric acid, C peptide and so on. The majority of children were effective by diazoxide.

  • The clinical characteristics of epilepsy patients treated with multi-drug combination therapy in Tibet plateau area

    Objective To explore the clinical characteristics of patients with combined use of ≥2 kinds of anti-seizure medications in Tibetan plateau. Methods Epilepsy patients who were hospitalized in the People’s Hospital of Tibet Autonomous Region from September 2018 to September 2023 and used ≥2 kinds of anti-seizure medications in combination were selected. Their demographic data such as gender, age, and ethnicity, as well as diagnostic information, medication and other clinical data were collected, and relevant demographic and clinical characteristics were analyzed. In the later stage, telephone follow-up was used to record medication and epileptic seizure control. Results A total of 2295 patients with epilepsy were included, of which 142 (6.2%) met the inclusion criteria, of which 133 (93.7%) were Tibetans. There were more males than females (86 vs. 56, P<0.05), and more minors and young patients than middle-aged and elderly patients (106 vs. 36, P<0.05). 87.3% of the patients underwent magnetic resonance imaging (MRI) or computed tomography (CT), and 71.1% of the patients were abnormal. The main cause of epilepsy was structural etiology (84/142, 59.2%). The most common combination was two drugs (127/142, 89.4%). The largest proportion of combination was sodium valproate and levetiracetam (46/142, 32.4%). After standardized multi-drug combination therapy, the average frequency of epilepsy seizures was significantly reduced compared with the baseline, and the difference was statistically significant (P<0.05). Among the 98 patients aged ≥14 years, 15 cases (15.3%) had drug-refractory epilepsy, 18 cases (18.4%) had seizures controlled by standardized combination medication, 16 cases (16.3%) had seizures controlled by reducing combination medication to a single drug, 5 cases (5.1%) had good control and had stopped medication, 3 cases (3.1%) had frequent epileptic seizures due to poor medication compliance, 15 cases (15.3%) had irregular medication, 17 cases (17.3%) died, and 9 cases (9.2%) were lost. Conclusion The proportion of epilepsy treated with multiple drugs and refractory to drugs was lower than the conclusion of previous studies, and the anti-epileptic effect of multiple drugs was positive. Structural causes (stroke, etc.) are the main causes of epilepsy, and brain parasitic infection is a unique factor of high-altitude epilepsy. Strengthening the standardized use of drugs will help improve the treatment status and prognosis of patients.

  • The relationship between serum homocysteine and post-stroke epolepsy

    Homocysteine is an intermediate product of methionine and cysteine metabolism, and plays a key role in methylation. Epilepsy is one of the common diseases of the nervous system, long-term repeated seizures will not only cause damage to the brain tissue, but also cause cognitive impairment. At present, the clinical treatment for epilepsy is still mainly to control symptoms, the fundamental etiology of epilepsy still needs to be improved, to explore the etiology of seizures, fundamentally control seizures, is still our long-term struggle direction. High homocysteine is associated with many diseases. Epidemiological studies have shown that the serum homocysteine level of 10% ~ 40% of epilepsy patients is higher than that of the normal population. By exploring the relationship between serum Hcy and epilepsy,We expect to provide help for the diagnosis and treatment of clinical epilepsy.

  • 高频脑电振荡:临床研究综述

    现代脑电图(EEG)技术的进步增强了对经典伯杰频段外,包含重要信息的脑电信号的识别。在癫痫领域,近十年的相关研究主要集中在发作间期>80 Hz 的高频振荡(High frequency oscillations, HFOs)。HFOs 大型临床应用始于癫痫手术术前的评估,近来也开始用于评估癫痫严重程度和监测抗癫痫疗效。该综述总结了 HFOs 在癫痫临床应用的证据,重点介绍了最新的进展。近期大量文献强调了 HFOs 与术后癫痫预后关系,一篇近期的 Meta 分析证实术后癫痫未发作患者 HFOs 切除率高于术后发作患者,利用术后 EEG 中的残留 HFOs 比术前 HFOs 率对癫痫手术预后预测更准确。文章深入讨论了区分生理性和癫痫性 HFOs 的尝试,这可能进一步加强 HFOs 的特异度。如睡眠结构分析表明,在痫灶内外对 HFOs 的偶联有差异。同时,越来越多的证据表明,HFOs 可用于对评估疾病活动度和利用非侵入性 EEG 和脑磁图(MEG)等检查中评估治疗效果。鉴于儿童 EEG 中 HFOs 比例高,这一技术在患儿中有良好的前景。在婴儿痉挛症中经促肾上腺皮质激素治疗后 HFOs 比例下降。在Rolandic区棘波时出现 HFOs 与发作频率相关。耗时的人工评估是过去 HFOs 临床应用的障碍,目前这一问题可由可靠的计算机算法解决。过去十年,HFOs 研究有了长足进展,利用非侵入性手段检测 HFOs 已在大量患者中得到应用。期待未来有多中心、大样本量研究获取长程监测资料,为这一领域提供更多信息。

  • 炎症、癫痫发作和癫痫发生:对人类疾病的探索

    癫痫在历史上被认为是一种神经元信号异常传导的疾病,表现为癫痫发作。随着大量自身抗体的发现和对自身免疫性脑炎认识的不断加深,人们越来越重视先天性和适应性免疫系统在癫痫发作和癫痫发生中的作用。在不同的癫痫发作相关的神经炎症和自身免疫疾病中,不同程度观察到了致病性抗体、补体激活、CD8+细胞毒性T细胞和小胶质细胞激活。这些异常的免疫反应被认为会导致神经元信号传导破坏,产生急性症状性癫痫发作,并且在某些情况下,还会发展为长期的自身免疫性癫痫。虽然早期使用免疫调节疗法可以改善自身免疫性脑炎和自身免疫性癫痫的预后,但患者的识别和治疗方法的选择并不总是明确。本篇综述讨论了免疫系统的不同成分在各种形式的癫痫发作中的作用,包括自身免疫性脑炎、自身免疫性癫痫、Rasmussen脑炎、热性感染相关性癫痫综合征和新发难治性癫痫持续状态。尤其是讨论了在这些疾病中观察到的病理生理学和独特的细胞因子谱,及其与诊断、预后和治疗决策的联系。
