  • 维生素 D 在生酮饮食治疗癫痫中的意义

    研究表明,维生素 D(Vitamin D,Vit D)在人类大脑和神经系统中扮演着重要角色。已有研究探索了 Vit D 在阿尔茨海默病、帕金森病、多发性硬化症、精神分裂症、情感障碍、认知衰退和癫痫等方面的作用,同时 Vit D 在神经系统中也起着神经营养、神经保护、神经传递等作用。研究证明,维生素 D 受体(Vitamin D receptor,VDR)普遍存在于神经元和神经胶质细胞乃至整个大脑、脊髓和周围神经系统中,故 Vit D 在神经系统中的作用从 VDR 也得到了证实。Vit D 在神经系统中的广泛作用提示了其在大脑中可能存在抗惊厥作用,而既往研究证明癫痫患者的 Vit D 水平普遍较低,且生酮饮食可能会进一步导致 Vit D 水平下降,因此,Vit D 的补充对于癫痫患儿以及生酮饮食治疗癫痫的疗效具有重要意义。

  • 经典生酮饮食和改良阿特金斯饮食治疗儿童难治性癫痫的效果比较

    研究旨在比较改良阿特金斯饮食(Modified Atkins diet,MAD)和经典生酮饮食(Ketogenic diet,KD)在治疗儿童难治性癫痫的疗效、安全性和耐受性。研究纳入 2011 年 3 月—2014 年 3 月就诊的 1~18 岁难治性癫痫患者,将其随机分配至一种饮食治疗组(ClinicalTrials.gov,编号 NCT2100501)。痫性发作记录被用于比较饮食治疗后 3、6 个月痫性发作频率与饮食治疗前基线发作频率。研究纳入 KD 组 51 例患者,MAD 组 53 例患者。KD 组平均基线痫性发作百分比在治疗后 3 个月(KD 组 38.6%,MAD 组 47.9%)和 6 个月(KD 组 33.8%,MAD 组 44.6%)均低于 MAD 组,但差异无统计学意义[3 个月,95%CI (24.1,50.8),P=0.291;6 个月,95%CI(17.8,46.1),P=0.255]。然而,在<2 岁患儿中,KD 组痫性发作控制效果优于 MAD 组。这些患者饮食治疗开始的 3 个月内,KD 组癫痫无发作率高于 MAD 组,差异有统计学意义(KD 组 53%,MAD 组 20%,P=0.047)。MAD 组耐受性更好并且副反应更少。MAD 可能是治疗儿童难治性癫痫的首要选择,但经典 KD 更适合<2 岁患者的一线饮食治疗方案。

  • 生酮饮食疗法历史浅谈

    生酮饮食是一种脂肪高比例, 碳水化合物低比例, 蛋白质和其他营养素合适的配方饮食。不仅治疗癫痫, 近来治疗其他疾病也在探索中。生酮饮食的前身是断食治疗, 断食不是完全断绝食物和水, 只是减少热卡, 维持饮水。为了更长时间维持断食的疗效, 1921年美国梅奥诊所出现了生酮饮食疗法。现在约翰.霍普金斯医院领导着全球的生酮饮食治疗。2004年我国大陆生酮饮食疗法临床开始于深圳市儿童医院。中国古老的辟谷疗法, 目前主要用于西医医院以外的养生保健, 操作和西方的断食疗法非常类似, 辟谷大约在2 500多年前就开始存在了。

  • 丙酮酸脱氢酶 E1α 亚基基因突变所致 Leigh 综合征的临床进展

    Leigh 综合征(Leigh syndrome,LS)是一种罕见的致死性亚急性脑病,是儿童线粒体病的常见表型,核基因及线粒体基因上多种基因位点突变均可导致这一罕见病,其中丙酮酸脱氢酶 E1α 亚基(PDHA1)基因所致的 LS(PDH-LS)约占比 10%,主要临床表现为肌无力、共济失调、神经退行性障碍等,但却缺乏特异性。该疾病预后较差,目前尚无特异性治疗方案,早期诊断及干预有助于改善 PDH-LS 预后,除了传统的药物治疗及改善营养状态外,生酮饮食亦是一种有益的治疗选择,因此早期明确诊断及相关基因型改变具有重大意义。LS 临床表现多变且缺乏一致的特异性,为早期诊断治疗带来了挑战。文章讨论了 PDH-LS 的临床表现,并总结了文献报道的 PDH-LS 患者的表现及有预警意义的表现,以期提高其早期诊断率和相关的治疗建议,希望能够对此类患者的诊治有所帮助。

  • 难治性癫痫合并语言障碍的生酮饮食治疗

    生酮饮食(Ketogenic diet, KD)疗法有近100多年的历史, 是一种高脂肪, 低碳水化合物, 合适的蛋白及营养素的配方饮食疗法, 目前被广泛运用到难治性癫痫的治疗当中, 取得了一定的疗效。越来越多的研究证据表明KD对难治性癫痫患者的认知功能的改善有一定的促进作用; 甚至有些病例癫痫发作控制不理想, 患者的语言功能和(或)运动功能也能得到一定的改善。KD治疗难治性癫痫的机制尚未完全明确, 但其疗效已被大量的研究证实; 对于癫痫所致语言障碍方面的生酮饮食治疗方面文献较少, 目前尚缺乏共识性的诊断和疗效判断标准。现就难治性癫痫合并语言障碍的定义及评价标准、癫痫和语言障碍的关系, 以及近年来KD对癫痫伴发语言障碍的治疗作用进展作一综述。

  • 生酮饮食治疗癫痫作用机制研究进展

    生酮饮食(Ketogenic diet,KD)是一种高脂肪、低碳水化合物,适量蛋白质、维生素和矿物质的饮食。KD用于治疗癫痫已有很长的历史,其疗效明确但作用机制尚不清楚。基于临床观察和研究,最初人们认为KD的作用机制与脱水、酸中毒相关。近几年,基于越来越多的动物实验和临床研究,人们逐渐提出了更多假说。KD减少了葡萄糖的摄入,机体利用葡萄糖受限,而酮体、脂肪酸升高,这可能与其产生抗癫痫作用相关。此外研究发现,KD的抗癫痫机制可能与神经递质、神经元兴奋性及突触传递有关。KD还有神经保护功能,如抗炎、氧化应激等,这与其抗癫痫作用也有关联。但是上述机制并不明确,目前关于KD的抗癫痫机制仍在探索之中。

  • Efficacy and safety of a very low-calorie ketogenic diet (VLCKD) in patients with overweight and obesity: a meta-analysis

    Objective To systematically review the efficacy and safety of a very low-calorie ketogenic diet (VLCKD) in patients who were overweight or obese. Methods From inception to August 2021, the electronic databases PubMed, EMbase, Web of Science, The Cochrane Library, CNKI, WanFang Data, VIP, and CBM were searched for randomized controlled trials (RCTs) of VLCKD in patients with overweight or obesity. Two reviewers independently screened the literature, extracted data, and evaluated the risk of bias of the included studies. Then, meta-analysis was performed using Stata 16.0 software. Results A total of 5 RCTs involving 245 patients were included. Among patients with baseline body mass index (BMI) ≥30 kg/m2, the meta-analysis showed that compared with the control group, VLCKD could significantly reduce the BMI (MD=−0.24, 95%CI −0.39 to −0.08, P<0.05), weight (MD=−7.00, 95%CI −10.48 to −3.53, P<0.05) and waist circumference (MD=−7.40, 95%CI −12.68 to −2.12, P<0.05) . The subgroup analysis results showed that compared with the control diet, VLCKD could significantly reduce the glucose (MD=−9.60, 95%CI −17.52 to −1.69, P<0.05), glycated hemoglobin (MD=−0.24, 95%CI −0.39 to −0.08, P<0.05), insulin resistance index (MD=−0.90, 95%CI −1.08 to −0.73, P<0.05) and triglycerides (MD=−41.42, 95%CI −53.78, −29.06, P<0.05) in patients with type 2 diabetes and with obesity or overweight. In patients with obesity or overweight, VLCKD could increase high-density lipoprotein cholesterol (MD=8.60, 95%CI 0.17 to 17.03, P<0.05) when the intervention lasted longer than 12 months. In patients with obesity or overweight, VLCKD had no effect on insulin, total cholesterol, low-density lipoprotein, urea, creatinine, or uric acid. Patients with VLCKD had a higher rate of adverse events than those in the control groups; however, there was no significant difference in the rate when the intervention lasted longer than 4 months. Conclusion The current evidence shows that VLCKD can reduce BMI, weight, and waist circumference and reduce fasting glucose, HbA1c, insulin resistance index, and triglycerides among patients with type 2 diabetes and with obesity or overweight. However, VLCKD has no effect on insulin, total cholesterol, low-density lipoprotein, urea, creatinine, or uric acid. Due to the limited quantity and quality of the included studies, more high-quality studies are needed to verify the above conclusion.

  • Study of correlation and status of compliance with ketogenic diet in children with refractory 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.

  • Efficacy and long-term retention rate comparision of ketogenic diet (KD) for children with intractable epilepsy in outpatient department and inpatient department

    ObjectiveTo compare the efficacy and compliance of children children with refractory epilepsy receiving ketogenic diet (KD) in outpatient department with children receiving KD treatment in inpatient department. MethodsA retrospective study of 44 children with intractable epilepsy receiving the modified classical ketogenic diets in outpatient department from June 2014 to December 2015, who were followed-up during the third, sixth and twelfth month. Records of epileptic seizures and adverse reactions were used to evaluate the efficacy and retention rate of inpatient department KD treatment in children with refractory epilepsy, and compared with 104 children receiving KD treatment in inpatient department at the same period. ResultsThirty-four of the forty-four children comleted observation after 12-month follow-up, 15 cases had been seizure freedom, 22 cases had more than 50% reduction in seizure frequency, 12 patients had less than 50% reduction in seizure frequency.The total effective rate of the KD therapy in outpatient department was 64.7%, and the retention rate was 71%. 18 of of the 104 children with KD treatment in inpatient department at the same period comleted observation after 12-month follow-up, 3 cases had been seizure freedom, 5 cases had more than 50% reduction in seizure frequency, 13 cases had less than 50% reduction in seizure frequency.The total effective rate of the KD therapy in inpatient department was 27.8%, and the retention rate was 17.3%. ConclusionThe KD therapy in outpatient department is effective to children with intractable epilepsy, and there is a highly efficacy and compliance of children receiving KD in outpatient department comparing with children receiving KD in inpatient department. Therefore, it's optional to children with refractory epilepsy who can't received KD by inpatient department because of insufficient number of beds.
