  • The aetiology and prognosis of convulsive status epilepticus: a study of 331 cases in Tibet Lhasa area

    Objectives Retrospective analysis of the Tibetan convulsive status epilepticus (CSE) for the aetiology, prognosis and its influencing factors in Tibet area. Methods Through electronic patient record, making “epilepsy”, “status epilepticus ”, “epileptic seizure” as keywords, convulsive status epilepticus patients in the People’s Hospital of Tibet Autonomous Region hospitalized from January 2015 to December 2020 were retrospectively observed, gathering their clinical data and aided examinations furthermore, and the prognoses were returned by telephone, meanwhile the functional status of those patients was assessed by the modified rankin scale. and the causes differ in gender, age, out-of-hospital antiepileptic treatment, family history of epilepsy and history of epilepsy were analyzed. The prognostic factors were analyzed by logistic regression. Results A total of 2 254 hospitalized patients with epilepsy were retrieved, including 331 CSE patients aged 14~84 years, 219 males and 112 females. There were 36 lost calls, 62 CSE deaths (21.01%), and 4 adverse outcomes (non-death)(1.7%).There were statistically significant differences in etiology of CSE in different ages and history of epilepsy (P<0.05), but there were no statistically significant differences in gender, out-of-hospital antiepileptic treatment, progression of refractory status epilepticus and family history of epilepsy. Cerebrovascular disease was the main cause of CSE in people aged 45 and over (54 cases), while the main cause of CSE in people aged under 45 was unknown (104 cases).Among the patients with previous history of epilepsy, the highest proportion was unknown cause [117 cases (48.8%)]; Among patients without a history of epilepsy, cerebrovascular disease [34 cases (37.4)] was the most common cause of CSE. Multivariate logistic regression analysis of prognostic factors of CSE showed that gender, age, GCS and electrolyte disorder had statistically significant effects on the death of CSE patients (P<0.05), while altitude and their duration and other factors had no statistically significant effects on the death of CSE patients (P>0.05). ConclusionsCerebrovascular disease is the leading cause of CSE in people aged 45 and over. Male, advanced age, low GCS score at discharge, and electrolyte disorder were risk factors.

  • Prognostic analysis of status epilepticus

    Objective To study the factors that affect the prognosis of status epilepticus (SE) and to improve the understanding of clinicians. Methods A retrospective analysis of 57 patients with SE witch from the General Hospital of Ningxia Medical University and Cardio-cerebrovascular Disease Hospital were carried out to collect their clinical data. The data were analyzed by SPSS 17.0 software. The prognosis of the patients was assessed by the Status epilepticus severity score (STESS) scale. Results A total of 57 patients were included, 53 cases improved, 4 cases were automatically discharged. Telephone follow-up showed that 4 cases of automatic discharge were dead. The mortality rate of SE was 7.02%. The most common cause of SE was acute cerebrovascular disease (17.54%), followed by intracranial infection (10.53%); The most common incidence were the occasional medication, self-medication, withdrawal (15.79%). Age, state of consciousness and concurrent infection were associated with prognosis (improvement/death) (P<0.05). STESS score of 0 to 2 points were 45 patients, all improved; score of 3 to 5 points were 12 patients, 8 patients improved, 4 patients died. There were significant differences in the prognosis between the two groups (P<0.05). Conclusions Age, state of consciousness, concurrent infection were related to prognosis, more than 65 years, the state of consciousness for the sleeping or coma had the poor prognosis. STESS scale can predict the prognosis of patients effectively.

  • Study on the expression of NGB in hippocampus after status epliepticus in rats

    ObjectiveTo observe the dynamic changes of neuroglobin (NGB) expression in hippocampus after status epilepticus(SE) in rats, and to explore the role of NGB in epileptic seizures.Methods40 healthy male Sprague Dawley rats were randomly divided into two group according to random number table method:control group (n=5) and epilepsy model group(n=35).Epilepsy model group according to observation time was divided into:0h, 1h, 3h, 12h, 24h, 10d and 30d.Intraperitoneal injection Lithium-pilocarpine (20 mg/kg~127 mg/kg, Li-PC) to establish the rat model of SE.Observe the behavioral changes in rats with epilepsy.Nissl staining was used to detect the neuronal damage in hippocampus. Streptavidin-biotin-peroxidase complex immunohistochemical method was used to detect the expression level of NGB in hippocampus;ResultsAfter SE, the neurons in hippocampus were severely damaged with the progress of epileptic seizures, the number of surviving neurons in CA1, CA3 regions showed a near linear decline.Among them, the number of surviving neurons in (12h, 24h, 10d, 30d)CA1, (0h, 12h, 24h, 10d, 30d)CA3 and(12h, 24h, 10d, 30d) DG area were significantly lower than that of the control group (P < 0.05).The expression level of NGB in CA1, CA3 and DG region of hippocampus were increased after SE, and both of CA1 and DG were reached peak in 24h after SE, but was still higher than the control group.And the CA3 area showed a continue rising trend.Among them, CA1(24h, 10d, 30d), CA3(24h, 10d, 30d) and DG(12h, 24h, 10d, 30d) were higher than that of control group significantly (P < 0.05).In addition, it was found that there was a positive correlation between the number of surviving neurons in CA3 area and the expression level of NGB (R=0.306, P=0.011).ConclusionUp-regulation of NGB expression in hippocampus after status epilepticus, and was positively correlated with the number of neurons in the CA3 area, suggesting that up regulation of NGB expression may be a compensatory protective mechanism of ischemic injury induced by seizures, and participate in the protection of epilepsy related neuronal damage.

  • The clinical analysis of ketogenic diet therapy in children with rapidly progressive Dravet syndrome

    ObjiectiveTo explore the efficacy and safety of ketogenic diet therapy (KDT) in the rapidly progressive stage of childhood developmental epileptic encephalopathy Dravet syndrome (DS). Methods The clinical data of all patients who added KDT in the Children’s Hospital of Fudan University from 2011 to 2022 were retrospectively collected, and the age of <6 years was used as the criterion for the rapid progression of the disease. The clinica data, genotype and the efficacy of KDT were analyzed in DS patients who met the criteria. Results A total of 32 patients met the criteria for rapid disease progress, including 22 males and 10 females. The age at onset was (5.69±2.10) months. All patients had multiple seizure phenotypes and monthly seizures despite reasonable Antiseizure medications treatment. After 3, 6, 12, and ≥24 months, 93.8% (30/32), 87.5% (28/32), 53.1% (17/32), 34.4% (11/32) remained on the KDT, while 76.7% (23/30), 75.0% (21/28), 70.6% (12/17), 54.5% (6/11) showed >50% reduction in seizure. Status epileptius (SE) was reduced by 100% at 3 months, 71.0% at 6 months, 86.0% at 12 months. After 12 months, 14 patients experienced efficacy degradation. After 3 months, the EEG background rhythm showed improvement in 75.0% patients, interictal epileptic discharges was decreased in 54.5% patients and cognitive function was improved in 78.6% patients. At the initial stage of KDT, 62.5% (20/32) patients had transisent adverse reactions, including diarrhea, vomiting, fatigue, lethargy, hypoglycemia, and metabolic acidosis, but no mid- and long-term adverse reactions were found. ConclusionKDT is an efficective and safe treatment for DS. KDT can effectively control seizures, reduce the incidence of Status SE and shorten the duration of SE. With the prolongation of the KDT course, some patients experienced a degraded effect. KDT can improve abnormal EEG and cognitive function in DS patients. Pharmoco-resistant DS patients are suggested to receive KDT in the early stage of disease progression.

  • Efficacy and safety of second-line medications for status epilepticus: a network meta-analysis

    ObjectiveTo systematically review the efficacy and safety of second-line medications for status epilepticus (SE). MethodsThe Cochrane Library, PubMed, EMbase, CNKI, CBM, and WanFang Data databases were electronically searched to collect randomized controlled trials (RCTs) of second-line medications for SE from inception to May, 2021. Two reviewers independently screened literature, extracted data, and assessed the risk of bias of included studies. Network meta-analysis was then performed using Stata 15.1 software and R 4.1.0 software. ResultsA total of 23 RCTs were included and 4 regimens were involved: levetiracetam (LEV), phenytoin/fosphenytoin (PHT), valproate (VPA), and phenobarbital (PHB). The results of network meta-analysis showed SE control rate validity sorting to be PHB>LEV>VPA>PHT, the epilepsy recurrence rate in 24 hour validity sorting to be VPA>PHB>LEV>PHT, those requiring further antiepileptic drug treatment rate validity sorting to be LEV>PHT>VPA, and drug safety security sorting to be VPA>LEV>PHT>PHB. Subgroup analysis showed PHB was optimal for SE control in children and adults, VPA had the optimal effect on other efficacy indicators in children, LEV was the safest in children and elderly patients, and VPA was the safest in adults. ConclusionsCurrent evidence suggests that PHB is the optimal for SE control, however, the safety is unsatisfactory; VPA and LEV have their own advantages in the treatment of SE, and their safety is satisfactory. VPA is recommended for adult patients, and LEV is recommended for children and elderly patients.

  • Nursing care of a patient with nonconvulsive status epilepticus accompanied by disturbance of consciousness

    According to their seizure patterns and EEG findings, status epilepticus can be divided into convulsive status epilepticus (CSE) and nonconvulsive status epilepticus (NCSE). Patients with NCSE have well-established EEG abnormalities without typical convulsive convulsions and only altered mental status or mild motor symptoms. Due to its atypical clinical symptoms, NCSE is prone to delayed diagnosis, misdiagnosis, or missed diagnosis, resulting in irreversible brain tissue damage, severe impairment of consciousness, function, and behavior, and even death in NCSE patients. It is of great significance to actively prevent seizures, identify symptoms early, and standardize treatment to improve the prognosis of NCSE patients. At present, there is no relevant standard and consensus on NCSE diagnosis and care. Here, we reported a patient with NCSE who admitted to the Epilepsy Center of Beijing Tiantan Hospital on June 21, 2024. After precise treatment and nursing, the patient's symptoms were well controlled, his condition was stable, and he was followed up for 1 month after discharge, and the prognosis was good. This case report aimed to provide some clinical suggestions to related disease.

  • Effect of electroacupuncture on apoptosis of hippocampal neurons in C57BL/6J mice with status epilepticus

    ObjectiveTo investigate the effect of electroacupuncture on the apoptosis of hippocampal neurons in C57BL/6J mice with status epilepticus by observing the changes of hippocampal subtle neuron pathology and apoptosis.MethodsMale C57BL/6J mice were used to prepare epileptic status models of lithium-pilocarpine mice, and then 7-day electroacupuncture stimulation (Baihui, Fengfu) were given to the mice model. Open field experiment and new object recognition experiment were performed to observe the changes of cognitive abilities. The pathological changes of hippocampal neurons were detected by HE staining. Hippocampal apoptosis protein (Caspase-3) and microtubule-associated protein (MAP-2) were detected by immunohistochemistry. Effect of electroacupuncture on apoptosis of hippocampal neurons in C57BL/6J mice with status epilepticus were recorded.Results① Compared with the control group, the vertical movement, modification times, and number of crossings of the model group all decreased significantly (P<0.000 1,P<0.000 1,P<0.000 1), and their cognitive ability decreased significantly (P<0.01). Compared with the model group, vertical movements, modification times, and number of crossings were increased in the electroacupuncture (EA) group (P<0.01,P<0.05,P<0.05), and the cognitive ability of new objects was increased (P<0.01). ② HE staining showed that the model group had significant damage to the hippocampal neurons of mice, and the cells swelled, nuclear collapsed and vacuoles appeared. In the EA group, the injury of hippocampal neurons was alleviated, and cell edema and vacuolization were alleviated. ③ Immunohistochemistry showed that compared with the control group, the IOD of the Caspase-3 positive cells in the hippocampus of the model group increased significantly (P<0.000 1), and the IOD of the MAP-2 positive cells decreased significantly (P<0.01); Compared with the electroacupuncture, the IOD of the Caspase-3 positive cells in the hippocampus of the mice decreased (P<0.05), and the IOD of the MAP-2 positive cells increased (P<0.05).ConclusionsElectroacupuncture can improve the pathological changes of hippocampal neurons in C57BL/6J mice with status epilepticus, promote cytoskeletal repair, reduce neuronal apoptosis in hippocampus, and antagonize the damage of hippocampal neurons induced by status epilepticus.

  • Clinical characteristics and prognostic factors of 33 children with status epilepticus

    Purpose To analyze the clinical characteristicsand prognostic factors of Status epilepticus (SE) in children. Methods The clinical data of 33 children with SE treated in Jinan Central Hospital Affiliated of Shandong University from January 2014 to June 2021 were collected, and their clinical characteristics were analyzed. Then, according to Glasgow prognosis scale, the children were divided into good prognosis group (n=20) and poor prognosis group (n=13). The age of first attack, duration of attack, type of attack and SE classification, EEG, cranial imaging and etiology were used to analyze the influencing factors of SE prognosis. Results 75.7% were 0 ~ 6 years old in the age of first attack, and 29 cases of convulsive status epilepticus accounted for 87.9% in the classification of seizure types. There were significant differences in age of first attack, duration of attack, EEG, history of mental retardation and etiology between the two groups (P<0.05); Logistic regression analysis showed that the age of first attack, duration of attack, history of mental retardation and EEG were independent factors affecting the prognosis. Conclusion Low age, especially ≤ 6 years old, is the high incidence of SE in children at first attack. Most children are symptomatic and have obvious incentives. Convulsive SE is the main type of SE in children. The age of first onset, duration of epilepsy, history of mental retardation, and EEG can affect the prognosis of SE.

  • 基于红藻氨酸和劳拉西泮联合给药的新型人类获得性颞叶癫痫动物模型

    红藻氨酸(Kainic acid,KA)是一种有效的谷氨酸类似物,用于诱导啮齿动物的神经退行性变和颞叶癫痫(TLE)。KA 可诱发严重的、持续的癫痫发作,即惊厥性癫痫持续状态(convulsive Status epilepticus,cSE),没有药物干预的情况下通常是致命的。在过去 30 年里,使用 KA 来建立人类癫痫动物模型毫无疑问被证明是有价值的,但显著的可变性和死亡率一直使结果变得不确定。这些问题很可能是 cSE 导致的,这是一种本质上可变且无法控制的全或无反应。然而,cSE 与人类疾病的相关性尚不确定,因为大多数癫痫患者从未经历过这种情况。该研究试图构建一种简单的、基于 KA 的 TLE 动物模型,以避免 cSE 及其混淆因素。成年雄性 Sprague-Dawley 大鼠分别接受皮下注射 KA(5 mg)和劳拉西泮(0.25 mg),剂量分别约为 15.0 mg/kg 和 0.75 mg/kg。持续的视频脑电图(VEEG)被用来监测急性癫痫的发作和检测自发性癫痫发作。免疫细胞化学、Fluoro-Jade B 染色和 Timm 染色被用来描述急性和慢性神经病理学改变。急性局灶海马癫痫发作在约 30 min 后开始并在几小时后自行终止。广泛的海马神经变性在 4 d 之后发现。在所有动物中自发性的局灶海马癫痫发作平均 12 d 之后开始。典型的海马硬化和苔藓纤维出芽的形成是长期神经病理学的特征。发病率和死亡率均为 0%。我们发现在联合注射低剂量苯二氮卓类药物时,KA 全身性给药的作用可局限于海马。这意味着劳拉西泮可以阻止痉挛性癫痫发作,而没有真正阻止癫痫电活动。这个创新的、无 cSE 的动物模型,可靠地模拟了获得性颞叶内侧癫痫所定义的特征:海马硬化和在长时间无癫痫发作后自发的海马起源的癫痫发作,并不伴显著的发病率、死亡率或无反应者。
