To characterize human leukocyte antigen (HLA) loci as risk factors in aromatic antiepileptic drug-induced maculopapular exanthema (AED-MPE). A case-control study was performed to investigate HLA loci involved in AED-MPE in a southern Han Chinese population. Between January 2007 and June 2019, 267 patients with carbamazepine (CBZ), oxcarbazepine (OXC), or lamotrigine (LTG) associated MPE and 387 matched drug-tolerant controls from six centers were enrolled. HLA-A/B/C/DRB1 genotypes were determined using sequence-based typing. Potential risk alleles were validated by meta-analysis using data from different populations and in silico analysis of protein-drug interactions. HLA-DRB1*04:06 was significantly associated with OXC-MPE ( p = 0.002, p c = 0.04). HLA-B*38:02 was associated with CBZ-MPE ( p = 0.03). When pooled, HLA-A*24:02, HLA-A*30:01, and HLA-B*35:01 additionally revealed significant association with AED-MPE. Logistic regression analysis showed a multiplicative interaction between HLA-A*24:02 and HLA-B*38:02 in CBZ-MPE. Meta-analysis of data from different populations revealed that HLA-24*:02 and HLA-A*30:01 were associated with AED-MPE ( p = 0.02 and p = 0.04, respectively). In silico analysis of protein-drug interaction demonstrated that HLA-A*24:02 and HLA-A*30:01 had higher affinities with the three aromatic AEDs than the risk-free HLA-A allele. HLA-DRB1*04:06 showed relatively specific high affinity with S-monohydroxy derivative of OXC. HLA-DRB1*04:06 is a specific risk allele for OXC-induced MPE in the Southern Han Chinese. HLA-A*24:02, possibly HLA-A*30:01, are common risk factors for AED-MPE. The multiplicative risk potential between HLA-A*24:02 and HLA-B*38:02 suggests that patients with two risk alleles are at greater risk than those with one risk allele. Inclusion of these HLA alleles in pre-treatment screening would help estimating the risk of AED-MPE.
The clinical data of a case of paroxysmal extreme pain disorder(PEPD) in Guangdong 999 Brain Hospital were retrospectively analyzed.The male patient, age of first examination was 7 months, began to have recurrent tonic accompanied by facial redness or cyanosis at 5 months after birth.The patient was diagnosed with epilepsy.The oral solution of sodium valproate and Levetiracetam were not effective.The video electroencephalogram examination displayed that, when the patient had tonic and bradycardia, the synchro electroencephalogram did not show epileptic discharge, so the patient was considered to have non-epileptic tonic.Genetic examination suggested that SCN9A gene mutation of c. 5240T >C resulted in amino acid changes: Val1747Ala.Combined with the skin changes, the patient was diagnosed as PEPD caused by SCN9A gene mutation.After the treatment with Carbamazepine, the patient′s abnormal skin changed and his-epileptic tonic disappeared, and his condition improved significantly.The early stage of PEPD can be mainly manifested as non-epileptic tonic.It is easy to be misdiagnosed as epilepsy, so the patient′s characteristic skin changes should be noticed, and genetic examination is also helpful in the diagnosis of the disease.
Background The ketogenic diet (KD) has been implemented in many different counties. However, in China, study concerning the efficacy of the KD is still at an early-stage of evaluation. Furthermore, the KD is thought to be incompatible with Chinese children because of its lack of palatability, especially for the Asian population. In addition, its substantial antiepileptic effect remains to be confirmed. Methods To evaluate the efficacy and safety of the KD treatment of refractory childhood epilepsy in China, we prospectively enrolled 147 children with refractory epilepsy for KD treatment in Guangdong 999 Brain Hospital and followed up the children for 6 months. Outcome was measured by seizure frequencies before and after the KD diet and adverse effects. We also evaluated influences of different variables (starting age, duration of epilepsy, and others) on the outcome. Results We found after 1 month, 3 months, and 6 months of KD treatment, 28.0%, 55%, and 67.9% of the subjects remained on diet with a >50% seizure reduction and seizure-free rates of 6.5%, 13.2%, and 23.3%, respectively. Gender, starting age, duration, etiology, classification, and seizure type of epilepsy showed no significant influence on efficacy. Anorexia, diarrhea, and gravel were the main side-effects of the KD treatment. Conclusions In conclusion, the KD is a safe and efficacious method for childhood refractory epilepsy treatment.
Objective:To investigate the clinical features of encephalocraniocutaneous lipomatosis (ECCL).Methods:The clinical characteristics, imaging manifestations and electroencephalogram changes of five patients with ECCL from Guangdong 999 Brain Hospital between December 2016 and February 2019 were collected and analyzed.Results:All five cases showed ocular, skin and central nervous system anomalies. Corneal anomalies were found in five cases, eyelid coloboma in three cases, calcification of the globe in two cases, and choristoma in one case. All five cases presented with naevus psiloliparis, three cases with small nodular skin tags on eyelids, and three cases with café-au-lait spots on the trunk. Dysplasia of the right cerebral hemisphere was observed in all five cases, four cases with enlargement of the right ventricle, three cases with arachnoid cysts, and one case with dysplasia of the corpus callosum. The onset of the seizures of five cases was found within one year old. Spasms were observed in five cases, partial seizure in three cases, and tonic seizure in one case. Five cases were drug-resistant epilepsy. Seizures decreased significantly after adrenocorticotropic hormone treatment in one case and seizures free after surgery in one case. One case had seizure free by corpus callosotomy, but had a relapse after four months. Three cases used ketogenic diet, including one case with epileptic seizure reduction, one case with development progress. All five cases had developmental delays. The exon gene sequencing of four cases was found normal. KRAS gene mutation was found in brain tissue of one patient.Conclusions:ECCL is a rare clinical disease that often involves the nervous system, skin and eyes. The seizures of the patients are often difficult to control and have development delays. Surgery may be necessary to control the seizures. ECCL is thought to be somatic mutations, which are hard to detect in the blood and can be found in affected tissues.

Antiepileptic drugs frequently cause cutaneous adverse reactions (cADRs). Numerous studies have reported associations between human leukocyte antigen (HLA) alleles and cADRs caused by single antiepileptic drug in Southern Han Chinese people. However, the relationship between the HLA allele and cADRs sequentially induced by two or more antiepileptic drugs (AEDs-induced cross-reactivity) is unclear. To explore the associations between HLA alleles and AEDs-induced cross-reactivity, we prospectively recruited patients with AEDs-induced cross-reactivity from 2009 to 2017 and performed high-resolution genotyping to detect the HLA-A, B, C, and DRB1 alleles in patients for comparison with normal controls. To verify the important genotype, we compared its presence in patients with cross-reactivity to enlarged normal controls, and its presence in patients with carbamazepine (CBZ)-induced maculopapular exanthema (MPE) to CBZ-tolerant controls. Further, the important allele was replicated by meta-analysis. Twenty-three patients with AED-induced cross-reactivity and 500 healthy individuals were enrolled from Southern China. All patients had a mild rash without mucosal or systemic involvement. The HLA-B*13:01 allele was present in 34.78% (8/23) of patients, 14.60% (73/500) of healthy individuals, and 14.5% (763/5,270) healthy individuals, revealing a significant association (8/23 vs. 73/500; P = 0.02; OR: 3.12; 95% CI: 1.28-7.62; 8/23 vs. 763/5,270; P = 0.014; OR: 3.15; 95% CI: 1.33-7.46). HLA-B*13:01 was presented numerically higher in CBZ-induced MPE than that in CBZ-tolerant individuals without statistical significance (33/145, 22.76%, vs. 28/179, 15.64%; P = 0.103). Meta-analysis revealed an association between HLA-B*13:01 and cADRs induced by single AEDs or/and non-AEDs in Chinese and Thai populations (P = 0.000). This study suggests that HLA-B*13:01 is potentially associated with AED-cADRs in general, possibly with stronger effect in cross-reactivity. Screening for HLA-B*13:01 prior to starting AEDs therapy may help to avoid cADRs. However, this association requires further analysis in a multi-center study with a larger sample size.

线粒体为环状的DNA分子,目前已确定有13个为蛋白质编码的区域,包括细胞色素B、细胞色素氧化酶的3个亚基、ATP酶的2个亚基、NADH脱氢酶的7个亚基;NADH脱氢酶(NADH dehydrogenation,ND)功能缺失是引起线粒体呼吸链受损最常见的原因,其基因突变会导致线粒体蛋白质合成受损,影响线粒体的电子传递链复合体亚单位和线粒体能源生产.根据线粒体DNA(mitochondrial DNA,mt-DNA)分子中碱基对位置,ND可分为ND1、ND2、ND3、ND4L、ND4、ND5、ND6共7个亚基.近年来,由ND1、ND3、ND4、ND5、ND6的基因突变导致的线粒体脑肌病屡见报道[1-5].其中,ND3在mt-DNA第10 059至10 404碱基对中,能产生由115种氨基酸构成的13kDa蛋白质,其结构呈“L-型”,长臂由疏水性跨膜结构组成,短臂为亲水性跨膜结构.其基因突变能引起多种线粒体脑肌病,包括线粒体脑肌病伴高乳酸血症和卒中样发作综合征(Mitochondrial encephalomyopathy with latic acidemia and strokelike episodes,MELAS)、Leber遗传性视觉缺失、Leigh综合征、线粒体脑肌病重叠综合征,合并或不合并肌张力障碍[6-10].
Neuronal ceroid lipofuscinosis is a hereditary disease, and ceroid-lipofuscinosis neuronal protein 5 (CLN5) has been proved to be associated with neuronal ceroid lipofuscinosis. Here we report 3 patients from 2 families diagnosed with CLN5 neuronal ceroid lipofuscinosis. Whole genome sequencing of DNAs from 3 patients and their families revealed 3 novel homozygous mutations, including 1 deletion CLN5.c718 719delAT and 2 missense mutations c.1082T>C and c.623G>A. We reviewed 278 papers about neuronal ceroid lipofuscinosis resulting from CLN5 mutations and compared Chinese cases with 27 European and American cases. The overall age of onset of European and American patients occur mainly at 3 to 6 years (66%, 18/27), 100% (27/27) of patients had psychomotor regression, 99% (26/27) patients presented vision decline, and 70% (19/27) of patients suffered seizures. In China, the age of onset in 3 patients was 5 years, but for 1 patient it was at 17 months. Four Chinese patients presented psychomotor deterioration and seizures; only 1 had visual problems.
