  • Observation of clinical effects of Lacosamide addition therapy in children with refractory epilepsy

    ObjectiveTo observe the clinical effect of Lacosamide (LCM) in the treatment of children with intractable epilepsy.Methods41 cases of refractory epilepsy patients who received LCM from March to July 2019 in department of Neurology, General Hospital of Henan Province were collected which included 21 males, 20 females, age were 4.6 ~ 15.5 years, average (7.21±3.06) years, And the efficacy of LCM was observed through blank control study.ResultsAfter LCM was added to the blank self-control group, the frequency of epileptic seizures was significantly reduced during the follow-up period of 3 months and 6 months, with statistically significant difference (P<0.05), and the mental state of the children was effectively improved, but there was no statistical significance between focal refractory epileptic seizure and comprehensive refractory epileptic seizure (P>0.05).ConclusionsLCM is a new kind of the third generation of antiepileptic drug. The addition use of LCM can effectively reduce the seizure frequency and improve mental state in children with refractory epilepsy.

  • 神经元移行障碍发病机制研究进展

    胚胎发育时期因各种因素引起的神经元移行障碍,常导致大脑皮质发育畸形(Malformation of cortical development,MCD),也是引起患儿发育迟缓和癫痫的常见原因。快速发展的分子生物学、影像学和基因遗传学丰富了大脑皮质发育的相关知识,畸形的报道不仅在数量和种类上有所增长,同时相关研究已经确定了几个基因,可能破坏神经细胞增殖、移行以及晚期皮层组织形成的每一个重要阶段。不同的MCD在临床表现上也有很大的表型异质性,现就MCD的发生机制、易感基因进行阐述,为MCD后期研究提供参考依据。

  • Genotype phenotype analysis and clinical research of 95 cases of children with epilepsy

    ObjectiveWe have summarized the clinical features of some refractory or genetically related children with epilepsy in clinical diagnosis and treatment and carried out the two generation of high-throughput gene sequencing and generation of verification on them. To analyze the relationship between mutant genes and epilepsy, to understand the genetic pattern of children and to look for possible pathogenic or disease causing mutation.MethodsEstablish a complete pedigree database for 95 children and their parents diagnosed in pediatric neurology clinic in our hospital from septeuber 2014 to Deceln ber 2016, and carry out gene testing on them by using two generation high-throughput gene sequencing. Then we have the analysis on the basis of clinical features and gene type in children.ResultsRefractory or genetically related children had a smaller age range and had a variety of clinical features. Most of them (47/95, 49.5%)needed two or more drugs for treatment; 28.4% of them was controlled which was about 27cases; 21.1% of them was effective which was about 20 cases; 33.7% of them was marked which was about 32 cases; 12.6% of them was of no effect which was about 12 cases; 4.2% of them was missed which was about 4 cases. a small number of children (18/95, 18.9%)had poor prognosis and accompanied with exercise and mental retardation. Genotype detection results: pathogenic genes of total 16 cases (16.8%)were cleared; there were about a total of 21 cases (22.1%)of possible pathogenic gene; there were about a total of 30 cases (31.6%)of non pathogenic gene; a total of 28 cases were not detected mutated gene which was about 29.5%.ConclusionsWe have found two new virulence gene of CASK and BRAF which had few reports in China and expanded the number of genes associated with neural development and epilepsy associated genes; the clinical characteristics of SCNIA gene mutations in Dravet syndrome were more serious which include earlier onset, frequent seizures and poor treatment effect; most children with specific causative genes required the combined use of two or more Anti-epileptic drugs, which has difficulties in treatme.

  • Analysis of genotypes and clinical phenotypes in two children with convulsions as the first symptom of hypoglycemia

    ObjectiveTo recognize the convulsion caused by hypoglycemia, and to analyze its genotype and clinical phenotype, so as to deepen the understanding of hyperinsulinemia.MethodFull exon detection were performed on 2 children with hypoglycemia and convulsions, who had been treated with antiepileptic drugs for 1 year in pediatric neurology department, Henan Provincial People’s Hospital in 2012 and 2014 respectively, but with poor curative effect.ResultABCC8 gene mutations were found in a child. The mutations located in Chromosome 11, with the nucleic acid changes of c.4607C>T (exon38) and the amino acid change of p.A1536V, rs745918247. The inheritancemode of ABCC8 gene could be autosomal dominant or autosomal recessive inheritance. Both of the parents were wild type on this genelocus. The gene mutation is associated with type 1 familial hyperinsulinemic hypoglycemia/nesidioblastosis. The other child was carrying GLUD1 gene mutation, witch is located in chromosome 10, with the nucleic acid changes of c.1498G>A (exon12) and the amino acid change of p.A500T. The inheritance mode of GLUD1 gene is autosomal dominant andthe child’s parents were both wild type. This gene mutationis associated with type 6 familial hyperinsulinemic hypoglycemia/nesidioblastosis. The 2 mutations have not been reported, which are new mutations.ConclusionMutations in these 2 gene loci may be the underlying cause of hypoglycemic convulsions, and are the best explanation for the poor convulsionscontrol of antiepileptic drugs.

  • Clinical features and literature review of 4 cases of DNA A3243G mutation-related MELAS syndrome

    ObjectiveTo investigate the clinical characteristics and genetic phenotype of mitochondrial myopathy associated with lactic acidemia and stroke-like seizure syndrome (MELAS) in DNA A3243G mutation, and to improve the clinical understanding and diagnosis.MethodsThe clinical data and imaging characteristics of 4 patients with DNA A3243G mutation-related MELAS syndrome who were diagnosed and treated in the Department of Pediatric Neurology, Henan Provincial People's Hospital from June 2017 to June 2018 were retrospectively reviewed.ResultsOf the 4 patients, 3 were caused by convulsions, 1 was caused by dizziness, and the MELAS syndrome caused by mitochondrial DNA A3243G mutation was confirmed by genetic testing. The patients were treated with anti-epilepsy drugs. The patients were followed up for at least 1 year, and 2 of 4 patients were stable, 1 patient still had seizures, and 1 patient did not improved.ConclusionsThe clinical phenotypic heterogeneity of patients with DNA A3243G mutation-related MELAS syndrome is caused by the " heterogeneity” and " threshold effect” of DNA mutation. The mutation rate of DNA A3243G is as high as 80%. In the era of promoting precision medicine, genes examination can help early diagnosis and early treatment of MELAS syndrome as well as improve the quality of life of patients and improve the prognosis.
