  • 作后血氨水平作为惊厥性癫痫发作的生物标志物:一项前瞻性研究

    有报道指出全面性惊厥性癫痫发作(Generalized convulsive seizures,GCS)后出现短暂性高血氨症(Transient hyperammonemia,THA),没有足够的证据证实与癫痫的关系。文章的目的是确定发作后THA是否可以区分不同类型的发作,如使用视频脑电图(VEEG)监测确认脑电变化。在前瞻性队列中,筛选了所有进入癫痫监测单元并同意接受研究的成年患者(> 18岁)。血氨的基础值以及在发作(所有患者)的60 min内、发作后24 h(只要有可能)的血氨水平均被检测。根据VEEG,将患者进行分组,分别为GCS、心因性惊厥性非痫性发作(Psychogenic nonepileptic seizures with convulsions,PNES-C)或局灶性癫痫发作(Focal seizures,FS)。使用描述性统计和参数/非参数方法分析数据。纳入患者78例,13例为GCS、8例为FS、9例为PNES-C。这些组在性别(P=0.04) 和血氨基础值(P=0.02) 方面是不同的,但年龄无差异。三组之间发作后血氨水平较血氨基础值的变化差异有统计学意义(P=0.004)。区分GCS与其他组差异的发作后血氨水平ROC曲线下面积为0.88[95%CI (0.69, 0.96)],表明检测血氨水平是一种很好的用来区分GCS与其他发作的试验。血氨水平≥80μmol/L可以准确为80%的患者分类(灵敏度53.9%,特异性100%)。VEEG监测为THA与GCS癫痫发作之间的关联提供了客观证据,并为今后关于确定发作后血氨水平作为GCS的廉价诊断试验作用的研究奠定了基础。

  • Effect of valproic acid coadministred with lamotrigine on epileptic patients' ammonia

    ObjectiveTo investigate the effect of valproic acid (VPA) coadministred with lamotrigine (LTG) on epileptic patients' ammonia and evaluate the influencing factors of elevated blood ammonia in epileptic patients.MethodsA retrospective analysis of clinical data from 146 patients with epilepsy (including newly diagnosed epilepsy patients) who were admitted to the Seventh Affiliated Hospital of Sun Yat-Sen University from May 2018 to April 2020 was performed. The patients were divided into no antiepileptic drug group (group A), VPA group only (group B) and VPA combined LTG group (group C), and the concentration of the blood ammonia of the patients were analyzed.ResultThe average ammonia levels in groups A, B and C were (18.14±1.19), (25.89±0.87) and (36.60±4.34) μmol/L, and the incidence of blood ammonia higher than normal were 2.77%, 8.89% and 20.0%, respectively.The difference between group B and group A and group C were statistically significant (P<0.05), the difference between group C and group A was statistically significant (P<0.05).ConclusionPatients with epilepsy who use VPA were at increased risk of blood ammonia and LTG can increase ammonia in epileptic patients who were treated with VPA. So when VPA was combined with LTG, more attention should be paid to ammonia of patient to avoid adverse reactions.
