  • Construction of a prediction model and analysis of risk factors for seizures after stroke

    ObjectiveConstructing a prediction model for seizures after stroke, and exploring the risk factors that lead to seizures after stroke. MethodsA retrospective analysis was conducted on 1 741 patients with stroke admitted to People's Hospital of Zhongjiang from July 2020 to September 2022 who met the inclusion and exclusion criteria. These patients were followed up for one year after the occurrence of stroke to observe whether they experienced seizures. Patient data such as gender, age, diagnosis, National Institute of Health Stroke Scale (NIHSS) score, Activity of daily living (ADL) score, laboratory tests, and imaging examination data were recorded. Taking the occurrence of seizures as the outcome, an analysis was conducted on the above data. The Least absolute shrinkage and selection operator (LASSO) regression analysis was used to screen predictive variables, and multivariate Logistic regression analysis was performed. Subsequently, the data were randomly divided into a training set and a validation set in a 7:3 ratio. Construct prediction model, calculate the C-index, draw nomogram, calibration plot, receiver operating characteristic (ROC) curve, and decision curve analysis (DCA) to evaluate the model's performance and clinical application value. ResultsThrough LASSO regression, nine non-zero coefficient predictive variables were identified: NIHSS score, homocysteine (Hcy), aspartate aminotransferase (AST), platelet count, hyperuricemia, hyponatremia, frontal lobe lesions, temporal lobe lesions, and pons lesions. Multivariate logistic regression analysis revealed that NIHSS score, Hcy, hyperuricemia, hyponatremia, and pons lesions were positively correlated with seizures after stroke, while AST and platelet count were negatively correlated with seizures after stroke. A nomogram for predicting seizures after stroke was established. The C-index of the training set and validation set were 0.854 [95%CI (0.841, 0.947)] and 0.838 [95%CI (0.800, 0.988)], respectively. The areas under the ROC curves were 0.842 [95%CI (0.777, 0.899)] and 0.829 [95%CI (0.694, 0.936)] respectively. Conclusion These nine variables can be used to predict seizures after stroke, and they provide new insights into its risk factors.

  • 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。

  • 癫痫发作期相关生物标志物的研究进展

    癫痫是一种由多种病因引起的慢性脑部疾病,以脑神经元过度放电导致反复性、发作性和短暂性的中枢神经系统功能失常为特征。临床上癫痫致病的原因及机制较为复杂,癫痫的诊断需要症状学及脑电图的支持。但是由于癫痫发作早期症状学较为隐匿且容易与其他发作性疾病相混淆,脑电图也可能表现为正常,因此,癫痫的早期诊断一般较为困难。回顾既往的研究报道,以癫痫发作期是否存在诊断性生物标志物为出发点,阐述与发作相关的血清学及脑脊液标记物,本综述主要关注癫痫发作期相关的蛋白、激素及炎症因子等方面,目的在于筛选出具有代表性的癫痫发作期相关生物标记物,为癫痫的早期诊断提供新的思路。

  • An analysis on clinical characteristics of 36 epileptics with pregnancy

    ObjectiveTo investigate the clinical characteristics of epileptics with pregnancy and then provide reference for standardized management of epileptics with pregnancy. MethodsFrom June 2012 to June 2021, epileptics with pregnancy who delivered in Jinan Central Hospital were selected as the research subjects. The clinical data such as the application of Antiseizure medications (ASMs) during pregnancy, seizure frequency, pregnancy outcomes, delivery ways, offspring feeding ways and the incidence of complications were investigated and analyzed. ResultsAmong 36 epileptics with pregnancy, 20 cases (55.56%) were treated with ASMs alone, 5 cases (13.88%) were treated with combined medication, and 11 cases (30.56%) were treated without ASMs during pregnancy. 15 cases (41.67%) adhered to systematic application of ASMs, 17 cases (47.22%) did not adhere to systematic application of ASMs, and 4 cases (11.11%) had unknown medication history. The frequency of seizures increased in 5 cases, decreased in 7 cases and unchanged in 24 cases during pregnancy. Pregnancy outcomes: full-term delivery in 33 cases (91.67%), preterm delivery in 1 case (2.78%) and abortion in 2 cases (5.56%). Delivery mode: cesarean section in 31 cases (91.18%), vaginal delivery in 3 cases (8.82%). After delivery, 4 cases (11.76%) were fed with milk powder and 30 cases (88.24%) were breast-fed. Complications: There were 6 cases complicated with anemia (16.67%), 5 cases complicated with gestational hypertension (13.89%), 3 cases complicated with gestational diabetes (8.33%), 4 cases complicated with premature rupture of membranes (11.11%), 2 cases complicated with fetal growth restriction (5.56%), 2 cases complicated with oligohydramnios (5.56%), 3 cases complicated with fetal distress (8.33%) and 3 cases complicated with neonatal asphyxia (8.33%). ConclusionsThe proportion of epileptics with pregnancy who were systematically treated with ASMs was low and the seizures were poorly controlled. There is a lack of standardized management for such patients in clinical practice.

  • 从病例看“自身免疫(相关)性癫痫” 在临床诊治中的挑战

    通过回顾性分析3例代表性临床病例的诊断、治疗及后期随访资料,以揭示目前有关“自身免疫(相关)性癫痫”在诊断和治疗方面存在的挑战和问题,并通过文献复习来探讨合理的应对策略。3例患者中,2例因反复癫痫发作就诊,在临床未明显提示免疫病因的情况下,多次送检相关抗体或启动免疫治疗。另1例患者临床除了癫痫发作,还有其他脑病表现,结合病史和影像所见高度提示免疫病因,最终经抗体检测阳性结果证实。3例患者的诊治经过提示,目前对“自身免疫(相关)性癫痫”诊断和治疗存在一定程度“过度化”情况。“自身免疫”和“癫痫”的关系较为复杂。自身免疫性脑炎中的癫痫发作和慢性自身免疫(相关)性癫痫之间的界限仍不清晰,缺乏可用于实际操作的标准(如生物标记物)是造成后者混乱临床诊疗现状的重要原因。现阶段,理清诸如“急性症状性发作”和“癫痫”等基本概念,仔细全面评估患者,尽早识别出自身免疫性脑炎中已经确定的、具有一定表型特征的综合征,以及使用可指导临床送检抗体或启动免疫治疗的相关评测量表,可帮助临床医生更加合理、有效地诊疗。

  • 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.

  • 癫痫发作的报警与预警

    癫痫是一种最常见的神经系统疾病,特点为多数发作无诱因且难以预测。发作可导致合并症,包括外伤及癫痫猝死(Sudden unexpected death in epilepsy,SUDEP),并致生活质量下降。过去20年广泛研究了发作的预警和报警,开发很多方法及设备,如头皮脑电图、颅内脑电图、肌电图、皮肤电变化、心率和心率变异性(Heart rate variability,HRV)。其中HRV是最有前景的方法。发作发放通过网络导致交感神经和副交感神经间不平衡并且改变了自主神经发放合并心率异常。过去20年用计算机方法开发了HRV的谱分析。HRV的变化早于脑电图发作和临床发作的开始。HRV可能是癫痫发作的预警和报警的指标。现在虽有很多关于癫痫的HRV算法,但是缺少标准的对于癫痫患者的方案,并且没有固定的监测模式,使之难以转化为临床实用,解决这个问题是十分重要的。总结出一个HRV评估的最低方案可用于所有癫痫患者的研究十分必要,可使HRV成为预警癫痫发作的有用工具。

  • 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。
