  • 婴儿痉挛的治疗进展

    婴儿痉挛是婴幼儿时期发生的一种难治性癫痫综合征,可表现为点头、环抱样发作,多以成串发作,少数可孤立性发作,发作表现有时轻微,常常被家长忽略而导致延误治疗,也是唯一一种发作症状轻微,但会导致严重不良后果的癫痫综合征。其病因种类繁多,虽然目前的研究已达基因水平,但仍有一些病例无法明确病因。其发病机制仍未完全阐明,有多种学说。对其治疗尝试了多种方法,虽然在某些病因为基础时得到了较好的成果,但多数婴儿痉挛仍是治疗的难题,预后较差,本文主要介绍婴儿痉挛的治疗进展,以供临床参考。

  • 神经炎症在婴儿痉挛发病机制中的研究进展

    婴儿痉挛(Infantile spasms,IS)是一种独特的,并有年龄依赖性的婴儿早期癫痫性脑病。具有发病年龄早、发作形式特殊、进行性认知损害、脑电图呈高峰失律等特征。其病因复杂、多样,发病机制尚未明确,治疗方面仍存在困难,大多遗留智能缺陷等后遗症。癫痫的发生与神经组织微环境中增加的强烈而持续的炎症状态相关,受损神经元组织中炎症细胞和分子的激活、分解调节障碍是癫痫发展的关键因素,炎症可能起源于中枢神经系统,或通过血脑屏障的破坏从全身循环获得。同时癫痫也可能激活促炎通路,导致神经炎症的发生。本文对近年神经炎症通路在 IS 发病机制中的作用研究进行综述,通过总结遗传学进展揭示了许多参与 IS 发病机制的基因,包括直接或间接参与炎症的基因,同时得到临床和 IS 动物模型的研究支持。了解 IS 发生发展过程中炎症的神经生物学将有助于开发新的生物标志物,以便更好地筛选高危患者,为探索 IS 治疗新靶点提供方向。

  • Vigabatrin for seizures treatment in patients with tuberous sclerosis complex: an efficacy and safety study

    ObjectiveTo evaluate the efficacy, tolerability and safety of vigabatrin (VGB) for seizure treatment in patients with tuberous sclerosis complex (TSC). MethodsForty-one epilepsy patients with tuberous sclerosis complex, admitted from January 2015 to December 2015, were included in our study; they were treated with VGB with an initial dose of 20 mg/(kg·d), and a maintenance dose of 50~ 100 mg/(kg·d). Baseline seizure frequency were evaluated by the parents or the guardian, and investigated the efficacy, tolerability, adverse reactions and safety in 3 and 6 months after treatment, and compared with the baseline. The treatment outcomes were evaluated by seizure frequency as completely seizure free (100% seizure reduction), markedly effective (75%~99% seizure reduction), effective (50%~74% seizure reduction) and invalid ( < 50% seizure reduction). Adverse reactions were observed during treatment. ResultsThe completely seizure free rates after 3 and 6 months treatment were 51.2% and 57.9%; and the total effective rates (completely seizure free+markedly effective+effective) were 90.2% and 89.5%.During the 6 months, only one patients stopped VGB use because of the poor efficacy and the difficulties to buy this medicine. 14 patients appeared adverse reactions, including drowsiness, agitation, hyperactivity and myoclonus, which were transient and mild. No patients had clinically perceivable visual-field changes on clinical examination. ConclusionVGB is a effective treatment in TSC patients with epilepsy, and have a good security in short term.

  • Analysis of the causes of infant spasm

    ObjectiveTo analysis the causes of infant spasm (IS) and provide a theoretical basis for clinical diagnosis and treatment. MethodsCollected the clinical data of 116 IS cases in our hospital from May 2011 to December 2013, which conform to the diagnostic standard, and analysis its causes. ResultsIn the116 cases we collected, symptomatic IS is primarily for 78 cases (67.24%); the onset age of symptomatic IS within 6 months was 76.39% (55/72), higher than the rates of symptomatic IS beyond 6 months 52.27% (23/44) (P=0.007); The pathogenic factor in symptomatic IS, prenatal accounted for 48.72%, intrapartum factors accounted for 34.62%; for sexually transmitted diseases accounted for 47.44%, venereal disease accounted for 52.56%. In 78 cases of symptomatic IS, gender has no relation with its pathogenic factors; the onset age within 6 months of antepartum and intrapartum factor is significantly higher than the rates of symptomatic IS beyond 6 months (89.09% VS 69.57%); distribution between urban and rural areas and its pathogenic factors is related, prenatal factors of urban IS significantly lower than which in rural areas (38.30% VS 64.51%), intrapartum factor IS significantly higher than the rural IS (44.68% VS 19.35%). ConclusionThe cause of the IS given priority to with symptomatic, IS in the majority with, and prenatal or developmental factors in the higher flight in symptomatic, and the smaller of the onset age antepartum and intrapartum factor becomes more apparent, prenatal factors in the rural areas is higher than which in the unban areas, but intrapartum factor in the unban areas is higher than which in the rural areas. Magnetic resonance imaging (MRI) still plays an important role in etiology diagnosis.

  • The advantage of diffusion weighted imagin technique in the toxicity detection of vigabatrin

    ObjectiveTo explore the differences in the detection of vigabatrin-associated brain abnormalities on MRI by different MRI sequences, so as to further guide the clinical understanding of VABAM and improve the appropriate imaging sequences. MethodsA total of 353 patients with infantile spasm or epileptic spasm who were admitted to the Epilepsy Center of Yuquan Hospital of Tsinghua University from January 2020 to January 2023 were retrospectively included. MRI was performed in 131 cases, including 3D T1, T2, T1- fluid-attenuated inversion recovery sequence (FLAIR) images, DWI and ADC sequences, of which 65 cases taking VGB. We aim to evaluate the detection of vigabatrin-associated brain abnormalities on MRI by different MRI sequences in these children. Results Among the 65 patients, VABAM was detected in 23 cases, the detection rate was 35.4%. The average dosage of vigabatrin was 100.73±35.54 mg/(kg·d). The positive detection rates of VABAM were 95.7% in DWI sequence, 26.1% in ADC sequence, 21.3% in FLAIR sequence, 4.3% in T2 sequence and 0 in T1 sequence. The detection rate of ADC sequence was significantly different from DWI sequence and T1 sequence, but not from T2 sequence and FLAIR group. ConclusionDWI sequence has irreplaceable advantages in the detection rate of VABAM. Therefore, for patients with infantile spasm and epileptic spasm who take vigabatrin, we should try our best to add DWI sequence scanning to improve the positive detection rate and avoid clinical symptoms, so as to avoid further brain damage.

  • Protocol optimization for treatment of infantile spasms with high dose prednisone

    ObjectiveTo optimize the therapy protocols of high dose prednisone combined with topiramate (TPM) in children with infantile spasms (IS). MethodsSixty cases were collected in our hospital from September 2012 to September 2013 and randomly divided into two groups(n=30) and followed-up for more than 6 months.The spasms were assesses by video-electroencephalogram (VEEG) monitoring including awake and asleep states before treatment, after two weeks of therapy and the end of the courses respectively.And the Gessel developmental quotient (DQ) scores were performed before treatment and after six months of therapy. ResultsFor the unresponders to high dose prednisone in one week of therapy, there were 46.67%and 60.00% in test group higher than 31.25% and 37.50% in control group respectively in 2 week and in the end of treatment.And the rate of complete resolution of hypsarrhythmia in the test group was 46.67% and 60.00% higher than 25.00% and 37.50% in control group respectively in 2 week and in the end of treatment.But there were no statistical significances between two groups(P >0.05).The incidence of side effects(83.33% vs. 80.00%) and the relapse rate(39.14% vs. 40.00%), were not statistically significant between two groups(P >0.05).The responsive rates for the cases with the lead time within 2 months higher than beyond 2 months in two groups respectively in 2 weeks and in the end of treatment. ConclusionsThe protocol of the test group was superior to that of the control group.The responsive rates of children within 2 months of lead time were higher than beyond 2 months, which indicates that early diagnosis and early treatment would improve efficacy and have an important influence on the prognosis of IS.
