Objective To assess the effectiveness and safety of flunarizine for refractory epilepsy. Methods Relevant randomized controlled trials (RCTs) were searched from the database of PubMed, EMbase, Cochrane Library, CNKI, CBM, and VIP, and the related references were traced to obtain the information. The methodological quality of included RCTs was assessed using Jadad scale and meta-analysis was performed using RevMan 5.0 software. Results A total of eight studies involving 545 patients were included. The results of meta-analyses showed that: based on the conventional therapy, compared with placebo and none-treatment, flunarizine was more effective on adults and children with refractory epilepsy (OR=2.98, 95%CI 1.88 to -4.73; OR=33.75, 95%CI 4.13 to -276.00). Major adverse events of flunarizine were fatigue, dizziness, headache, and weight gain etc. All those symptoms except for the weight gain were observed in the early stage of medication, which might get self-cured or could disappear by constant medication or reducing the dose or symptomatic treatment. Conclusion The present study shows that based on the conventional therapy, flunarizine is effective and safe for refractory epilepsy.
ObjectiveTo observe the clinical efficacy of Xiao’er kang xian capsule added to anti-seizure medications (ASMs) in the treatment of children with refractory epilepsy and its influence on serum neuron-specific enolase (NSE) and cludter of differentiation 19+ (CD19+) levels. Methods A total of 60 children with refractory epilepsy were selected from the pediatric outpatient department and ward of Guangdong Provincial People's Hospital from February 2021 to June 2023. The study subjects were divided into two groups by numerical random method,with 30 cases in each group. The children with Xiao’er kang xian capsule added to the original treatment were the treatment group and the children without Xiao’er kang xian capsule added to the original treatment were the control group. The frequency, duration, EEG characteristics, adverse reactions and changes in serum NSE and CD19+ levels of the two groups were compared after treatment. Results Self-control before and after treatment in the treatment group: the frequency and duration of seizures were significantly reduced, with statistical difference (P<0.05). EEG discharge index in awake period and sleep period were significantly decreased, with statistical difference (P<0.05). After 6 months of treatment, comparison between the two groups of children: the seizure frequency of children in the treatment group was significantly decreased compared with the control group (P=0.03). There was a statistical difference (P<0.05), and the seizure duration in the treatment group was less than that in the control group (P=0.863), the clinical effective rate of treatment group 83.33% was higher than that of control group 63.33% (P=0.08), the effective rate of EEG in treatment group 80% was higher than that of control group 60% (P=0.091), serum NSE and CD19+ in treatment group were lower than that of control group, with no statistical difference (P>0.05). After 12 months of treatment, the frequency and duration of seizures in the treatment group were significantly decreased (P<0.05). The clinical efficacy and effectiveness of treatment group were significantly higher than that of control group (P=0.038). The incidence of adverse reactions in both groups was 16.67% (P>0.05). The effective rate of EEG in treatment group was significantly higher than that in control group (P=0.053). Serum NSE and CD19+ in treatment group were significantly lower than those in control group (P<0.05). ConclusionFor children with refractory epilepsy, the addition of Xiao’er kang xian capsule on the basis of the original treatment has obvious effect low adverse reaction and high safety. NSE and CD19+ can be used as monitoring indicators for the influence of the disease and prognosis evaluation during the treatment of children with epilepsy.
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.
Objective To observe the efficacy and adverse reactions of pirenpanet in patients with refractory epilepsy treated with add-on therapy. MethodsForty-one patients with medically refractory epilepsy were selected from January 2021 to December 2021 in the Department of Epilepsy of Jiamusi Central Hospital, among which 25 males and 16 females. The self-control study was conducted before and after the treatment with pirenpanet. The observation period was 1 year, and the clinical efficacy, platelet, liver and kidney function and EEG discharge index were observed at 6 months and 12 months respectively. Changes in seizure frequency after treatment were divided into the following 3 groups: effective control: no seizure; effective: seizures reduced by 50% ~ 99%; Ineffective: < 50% reduction in seizures or exacerbation. Results Among the 41 patients with drug-refractory epilepsy, 8 (8/41, 19.51% P < 0.05) were seizure-free, 17 (17/41, 41.46% P < 0.05) were effective, and the total effective rate was (25/41, 60.98%); Sixteen cases (16/41, 39.02%) were ineffective. There were 31 children in 41 cases (31/41, 75.61%), of which 18 cases (18/31, 58.06%) were effective, 16 cases (16/31, 51.61%) had mental and motor retardation, and 8 cases (8/16, 50%) were effective; There were 10 adults (10/41, 24.39%) and 7 effective patients (7/10, 70%). After one year's treatment, the EEG changes of the patients were observed, and the abnormal discharge of 6 patients was reduced according to the discharge index, 2 patients had no abnormal discharge, and the other patients had no obvious EEG changes. Conclusion Pirenpanet is effective and safe as an add-on therapy for medically refractory epilepsy.
Objective To investigate the clinicalmanifestations, electroencephalogram (EEG) characteristics, surgical treatment and prognosis of epilepsy secondary to Sturge-Weber syndrome (SWS) in children.Methods The data of 7 children with epilepsysecondaryto Sturge-Weber syndrome who were treated by surgery from May 2015 to May 2020 in our Children's Epilepsy Center were retrospectively reviewed. Their demographic characteristics, seizure forms, results of EEG and cranial imaging investigations, surgical methods, postoperative pathological reports and prognosis during follow-upwere summarized and analyzed. The prognosis were evaluated byEngel classificationat the last time point during follow-up. Results Totally 7 pediatric patients were enrolled, including 1 male (16/25, 64.0%) and 6 females.All the 7 cases presented with focal seizures at the onset among whom 2 cases developed status epilepticus during the course of the disease(epilepsiapartialiscontinuain 1 case),one case had epileptic spasmsand 1 case was characterized by cluster seizures. The interictal EEG manifestations of the cases gradually deteriorated as the course of the disease prolonged, including the slow wave on the affected side gradually increases (7/7), the amplitude gradually decreases (7/7), and the physiological wave disappears (4/7). Besides, no epileptiform discharges/incidental or a few epileptiform dischargeswere found in their interictal EEGs. Four cases underwent hemispherotomy, 1 case underwent temporo-parieto-occipital disconnection and 2 cases underwent lesion resection. The cases were followed up for 6 months to 5 years, and the average follow-up duration was 79.29 months. Six cases were rated as Engel Ⅰa during the regularfollow-up. Only 1 case was rated asEngel Ⅱ and Engel Ⅲ at 3 month and 1 year after the operation. ConclusionChildren with epilepsy secondary to SWS usually present with focal seizures and have diverse seizure forms. The EEG show characteristic changes. For the caseswith drug refractory epilepsy, detailed preoperative evaluation and reasonable surgical methods can result in a better therapeutic effect.
ObjectiveAccording to the diagnosis and treatment analysis of 5 children with Febrile infection-related epilepsy syndrome (FIRES) and literature review, to explore the therapeutic effect of Ketogenic diet (KD).MethodsA retrospective analysis of the clinical status of 5 children with KD treatment of FIRES admitted to the Department of Pediatric Neurology, West China Second Hospital of Sichuan University from August 2016 to September 2019, combined with literature data, summarized their disease characteristics, prognosis and KD treatment effects.ResultsThe 5 cases of FIRES children were (5.8±2.0) years old and had a male to female ratio of 2∶3. They were all induced by fever followed by a status epilepticus that was difficult to control with drugs. The interval between fever and first seizure was 4 to 7 days, and the prodromal symptoms were higher respiratory tract infections, dizziness, vomiting, fatigue, listlessness, loss of appetite, etc., convulsions manifested as focal or focal secondary systemic or general seizures, EEG showed slowing background rhythm, changes in multifocal epileptic discharge, early course of disease The cranial imaging examination was basically normal. As the course of the disease progressed, changes in brain atrophy gradually appeared, and abnormal signal shadows were seen in the forehead, parietal, occipital lobe, and periventricular. A variety of anti-epileptic drugs, hormones, gamma globulin, plasma exchange and other treatments have poor therapeutic effects and severe cognitive impairment. The KD treatment started to take effect within 2 weeks, and the convulsions were reduced. One case was completely controlled, and the cognitive function basically returned to normal with only mild learning disabilities; the convulsions were reduced by more than 50% in 2 cases, leaving mild to moderate cognitive impairment, The other 2 cases had poor long-term treatment effects, left intractable seizures and severe mental retardation.ConclusionFIRES is a serious epileptic encephalopathy, most of which leave severe cognitive impairment and refractory seizures. Drug therapy and prognosis are poor. KD treatment is beneficial to control seizures in children with FIRES in the acute stage.
Objective To study the efficacy and adverse events of adjunctive perampanel in children with refractory epilepsy. Methods A prospective study was carried out in 45 children with refractory epilepsy, who were treated in our hospital from January 2020 to February 2021 using perampanel as an add-on treatment, with a criteria for enrollment and the starting dose of perampanel. Follow-up would be taken at once a month. Afte 3 months would check blood routine, liver function, kidney function and humoral immunity. The EEG was reviewed after 6 months. The initial dose of perampanel was 0.04 mg/(kg·d) (the maximum didn't exceed 2 mg/d), increasing by 0.04 mg/(kg·d) every two weeks, and the maximum maintenance dose didn't exceed 6 mg/d. The efficacy and adverse reactions of perampanel were evaluated by comparing the seizure frequency and EEG results before and after a 6-month add-on therapy.ResultsAmong the 45 children,complete seizure control was achieved in 7 cases after the therapy, and the seizure attacks were reduced in 26 cases, showing a total response rate of 73.3%. After the treatment, the epileptiform discharge of 28 children was reduced, and the effective rate was 62.22%. During the observation period, all the blood routine, liver function, kidney function,and humoral immunity of the children were normal.10 cases of adverse reactions occurred after the additional treatment of perampanel, and the adverse reaction rate was 22.22%. Conclusions Perampanel has good efficacy and safety in the add-on treatment of refractory epilepsy.
ObjectiveTo investigate the clinical effect of Electro-Cortico-Graphy (ECOG) monitoring on refractory epilepsy caused by double pathology. MethodsA retrospective analysis was performed on 10 patients with refractory epilepsy who underwent surgical treatment in Hunan Brain Hospital from January 2020 to December 2021. The diagnosis of postoperative disease was dual pathology of medial temporal lobe sclerosis (MTS) and focal cortical dysplasia (FCD), and the effect of oral drugs was poor. All patients underwent full preoperative evaluation to determine the scope of excision of epileptogenic lesions. Cortical electrodes were used to monitor the location and scope of epileptic discharge during the operation. Epileptogenic lesions were excised, cortical heat cautery was performed, and then cortical EEG monitoring was performed to adjust the excision strategy. The patients were followed up for 24 to 48 months, and the prognosis was assessed according to the Engel scale. ResultsAmong the 10 patients, 1 patient had acute subdural hemorrhage after surgery, 1 patient had speech and naming disorders, but all of them were recovered at discharge. The other patients had no neurological defects such as intracranial infection, hemiplegia, aphasia, etc. Engel grade I was observed in 9 cases (90%) and Engel grade III was observed in 1 case (10%). ConclusionCortical electrode monitoring is safe and effective for refractory epilepsy caused by double pathological signs.
Objectives To investigate the changes of serum monoamine neurotransmitters and myocardial enzymes in patients with refractory epilepsy (RE), and the possible effects on the cardiovascular system, which would contribute to provide help and guidance to the early warming and prevention to the sudden unexpected death in epilepsy (SUDEP). Methods We collected sixty patients with RE who admitted to Neurological department of First Hospital of Jilin University from December 2015 to December 2016. According to the exclusion criteria, we selected thirty-two patients into the study. The study included 21 males and 11 females patients. Epinephrine (EPI), norepinephrine (NE), dopamine (DA), 5-hydroxytryptamine (5-HT), creatine kinase isoenzyme (CKMB), lactate dehydrogenase (LDH) and hydroxybutyrate dehydrogenase (HBDH) were measured in peri-ictal period and the interictal period in the patients. All the data were analyzed by SPSS17.0 statistical software. Results ① Thirty two patients were eligiblefor this study and the maleto female ratio is 21:11; The age ranged from 15 to 85 years old, with the average age of 50.9±17.6 years old. Twelve (37.5%) were older than 60 years old and 20 (62.5%) were under 60 years old. The epilepsy history ranged from 1 year to 14 years, with an average of 3.75±3.12 years; ② Comparing the levels of monoamine neurotransmitters in peri-ictal period and the interictal period in the patients with RE, we found that the level of EPI and LDH was significantly lower than that in interictal period, while the levels of NE and DA were significantly increased; ③ The results showed that EPI, NE and DA levels in patients under 60 were higher than over 60; ④ Patients were divided into four groups according to the etiology of the disease: idiopathic epilepsy group (10 cases, 31.25%), post-encephalitic epilepsy group (7 cases, 21.88%), post-stroke epilepsy group (9 cases, 28.12%) and epilepsy after brain injury group (6 cases, 18.75%). The results showed that the levels of EPI, NE and DA in the post-strokeepilepsy group were significantly lower than those in the other three groups. The level of CKMB in the idiopathic epilepsy group was higher than that in post-stroke epilepsy and epilepsy induced by brain injury patients. Conclusions RE patients have a higher level of serum NE and DA interictal period, suggesting that seizures may increase sympathetic nervous excitability. The patients under 60 years-old with RE release more catecholamines than young patients, suggesting that the latterwith intractable epilepsy may have higher sympathetic nerve excitability. And it may be associated with the higher incidence of SUDEP in young patients. Post-stroke epilepsyrelease less catecholamine than others, suggesting that the sympathetic nervous excitability is relatively low, and it may have relatively little damage to heart.
ObjectiveTo analyze the clinical efficacy and safety of rapamycin in the treatment of Tuberous sclerosis complex ( TSC ) complicated with refractory epilepsy, and to provide scientific basis for the clinical treatment of this disease.MethodsRetrospective analysis was performed on 22 children with TSC complicated with refractory epilepsy admitted to Henan People's Hospital from 2017 to 2019, including 11 males and 11 females who met the inclusion criteria, with an average age of (27.91±36.92) months. They were treated with antiepileptic drugs and rapamycin at the same time, and followed up for at least 1 year.To observe the change of seizure frequency before and after treatment with rapamycin.ResultsThe mean reduction rate of seizure frequency in children with tuberous sclerosis complicated with refractory epilepsy was 52.1% 6 months after the addition of rapamycin, and 51.2% 12 months after the addition of rapamycin. The number of seizure-free days could be maintained. The difference before and after the addition of rapamycin was statistically significant (P<0.05).ConclusionThe addition of rapamycin in the treatment of TSC complicated with refractory epilepsy can reduce the frequency of seizure and increase the number of days without seizure, and the adverse reactions are mild/moderate. Rapamycin has certain safety in children with regular follow-up.
