Objective To explore the efficiency of Vigabatrin for epilepsy in children with Tuberous Sclerosis Complex, and to further research the risk factors related to the outcome after adjunctive use of Vigabatrin. Methods 25 children with TSC and epilepsy treated with Vigabatrin at Children′s Hospital of Fudan University between 2013 and 2015 were included. Clinical characteristics and the effectiveness of other antiepileptic drugs were extracted from the follow-up data. The prevalence of visual field defect was analyzed among the cases. And correlations were made between the responses to Vigabatrin in groups. Results 25 cases, 15 male (60%). 18 cases had response to VGB-adjuvant therapy. Children with epilepsy onset at greater than six months of age were most likely to demonstrateagood response to VGB treatment. And the poorly response of cases showed that 4 had TSC1 mutation. And among the 25 cases, one child had the visual filed defect. Conclusions Vigabatrin as adjunctive therapy showed certain effect in controlling epilepsy in TSC cases, especially infantile spasms and some partial epilepsy. But the side effect of visual filed defect should be cautious. Age-appropriate visual field testing is recommended at baseline and then repeated at intervals in patients exposed to long term Vigabatrin therapy.
Objective To investigate the compliance of ketogenic diet in children with refractory epilepsy and its correlation with the curative effect, and to provide support and basis for the implementation and improvement of the long-term management of ketogenic diet in this patient population. MethodsA total of 106 children and their families who were followed up on ketogenic diet in the Department of Pediatrics of Fudan University from March 2019 to January 2022 in the Department of Ketogenic Multidisciplinary Treatment (MDT) were selected by convenience sampling method. General data questionnaire and ketogenic compliance questionnaire were used for investigation and follow-up. ResultsThe mean compliance of ketogenic diet in refractory epilepsy children was (13.27±3.68). The compliance scores of ketogenic children with different therapeutic effects and cognitive functions were significantly different. The compliance score was significantly correlated with the therapeutic effect and cognitive level, that is, the higher the therapeutic effect of ketogenic diet in children with higher compliance score, the better the cognitive improvement. ConclusionThe compliance of ketogenic diet in children with refractory epilepsy needs to be further improved. Improving the compliance of ketogenic diet is of great significance for the efficacy of ketogenic diet. Medical staff should actively develop the corresponding intervention program and follow-up management mode to further improve the treatment compliance of children's families, improve the treatment effect and improve the quality of life of children's families.
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.
ObjectiveTo explore the clinical, genetic and prognostic features of early infantile epileptic encephalopathy caused by DNM1 gene pathogenic variations.MethodsClinical phenotype, genotype and prognosis of 3 individuals with de novo variants in DNM1 gene were analyzed retrospectively. Through using “Dynamin-1” or “DNM1” as key words to search literature at database of China National Knowledge Infrastructure, Wanfang, PubMed and OMIM. Genotype-phenotype correlations were analyzed by analysis of variance (ANOVA).ResultAmong the 3 patients, 1 female and 2 males. 2 cases with epileptic spasm and 1 case with focal clonic seizure or secondary generalized tonic-clonic seizure were manifested with onset age from 2 to 17 months. De novo variants at NM_004408.4: c.415 G>A(P. Gly 139Arg) in 2 inviduals and NM_004408.4: c.545 C>A(P. Ala 182Asp)in 1 invidual of DNM1 gene were identified by gene testing. After follow-up at age of 2~3 years, all patients were presented with hypotonia, severe intellectual disability, non-verbal, non-ambulatory, drug-resistant epilepsy and feeding difficulties. 36 cases with pathogenic DNM1 variants were reported by far, totally 39 cases were included. Of the 39 patients, hypotonia were found to be independent of the locus of genetic variants, while those inviduals with variants in the GTPase and middle domains almost presented severe or profound intellectual disability and epilepsy. 31 patients diagnosed with epilepsy and complete clinical data were further analyzed, epileptic spasm was the most common types of seizure. Absent seizure was significantly more common in those patients with variants in the GTPase domains (P=0.02), compared to those patients with variants in the middle domains. No statistical differences were found in gender, onset age, other types of seizure and drug treatment response between variants in the GTPase and middle domains.ConclusionHypotonia, early onset epilepsy, severe intellectual and movement disability were the common features in patients with DMN1 related encephalopathy. Epileptic spasm was the most common types of seizure, no significant differences were found in the phenotype between the GTPase and middle domains expect for absent seizure. Our patients also presented with feeding difficulties.
Objective To investigate clinical features and surgical outcome in children with frontal lobe epilepsy by evaluating the correlation between the predictive factors and seizure freedom. Methods 18 children who underwent frontal lobe epileptogenic resection in the Epilepsy Center of the Children's Hospital of Fudan University between January 2017 and December 2019 with a minimum follow up of 2 year were analyzed retrospectively. Each patient was evaluated with detailed data to predict postsurgical seizure freedom by analysis of variance. Results Of the 18 patients, there were 11 males and 7 females, the age at surgery ranged from 21 months to 11 years old (6.8±2.73) and the duration of seizures was from 1 month to 9 years. 17 patients had focal seizures, while 1 had generalized epileptic spasm. In scalp EEG, interictal and initial ictal discharges were frontal in 11 and 9 cases, respectively. MRI was indicative of FCD in 10 cases, tumor in 2, tuberous sclerosis and gliosis lesion in 1 case each. 4 patients were MRI negative. 11 patients underwent epileptogenic lesion resections directly and 7 cases received depth electrodes implantation and underwent stereo-electroencephalography to localize epileptogenic zone. At follow-up of 2 years, 14 (77.8%) patients remained seizure-free (Engel Ⅰ), 1 (5.6%) had marked seizure reduction (Engel Ⅱ), 2 (11.0%) showed minor improvement (Engel Ⅲ), and only 1 (5.6%) showed no response (Engel Ⅳ). About predictors of seizure recurrence, there were no significant differences in gender, age at surgery, age of seizure onset, duration of epilepsy, lateralization of epileptogenic zone, positive MRI findings, interictal and ictal discharge, etiology, intellectual development and stereo-electroencephalography implantation, while significantly higher rates of seizure freedom correlated with complete the resection of the epileptogenic zone. Conclusions Focal cortical dysplasia is the most common cause in childhood with frontal lobe epilepsy and complete resection of the epileptogenic zone can lead to good seizure control outcome.
