ABSTRACT

Epilepsy is one of the most disabling neurological diseases. Despite proper pharmacotherapy and the availability of 2nd and 3rd generation antiepileptic drugs, deep brain stimulation, and surgery, up to 30-40% of epilepsy patients remain drug-resistant. Consequences of this phenomenon include not only decreased a quality of life, and cognitive, behavioral, and personal disorders, but also an increased risk of death, i.e., in the mechanism of sudden unexpected death in epilepsy patients (SUDEP). The main goals of epilepsy treatment include three basic issues: achieving the best possible seizure control, avoiding the undesired effects of treatment, and maintaining/improving the quality of patients' lives. Therefore, numerous attempts are made to offer alternative treatments for drug-resistant seizures, an example of which is the ketogenic diet. It is a long-known but rarely used dietary therapy for intractable seizures. One of the reasons for this is the unpalatability of the classic ketogenic diet, which reduces patient compliance and adherence rates. However, its antiseizure effects are often considered to be worth the effort. Until recently, the diet was considered the last-resort treatment. Currently, it is believed that a ketogenic diet should be used much earlier in patients with well-defined indications. In correctly qualified patients, seizure activity may be reduced by over 90% or even abolished for long periods after the diet is stopped. A ketogenic diet can be used in all age groups, although most of the available literature addresses pediatric epilepsy. In this article, we focus on the mechanisms of action, effectiveness, and adverse effects of different variants of the ketogenic diet, including its classic version, a medium-chain triglyceride diet, a modified Atkins diet, and a low glycemic index treatment.

ABSTRACT

BACKGROUND: A diagnosis of drug-resistant epilepsy is life changing for a family. Ketogenic diet therapy (KDT) can offer hope when other treatments have failed. However, it often requires a significant change in daily routine and dietary habits. This qualitative descriptive study aimed to explore families' experiences of epilepsy and KDT. METHODS: Parents of a child aged ≤18 years with epilepsy, currently or recently treated with KDT, were recruited from the UK and internationally via UK Ketogenic Diet (KD) centres, charities, and social media. Semi-structured interviews were audio recorded, transcribed verbatim, anonymised, coded using Nvivo (V12), and inductive thematic analysis undertaken. RESULTS: Twenty-one parents participated. Four themes and 12 subthemes emerged: 1. 'Epilepsy is all consuming' explored the impact of epilepsy on the family. 2. 'KD provides a window to new opportunities' explores the motivators for KDT and positive outcomes. 3. 'The reality of KD' explores day to day life and how families adapt to KD. 4. 'Looking to the future' explores the factors that may make KD easier for families. All were glad their child trialled KD, even when less successful. The importance of a support network including family, friends, charity organisations and the KD team was evident across all themes. CONCLUSIONS: We conclude with five recommendations to help support families in their management of KDT; Improved access to KDT and transition to adult services, access to quality education and support, enhanced variety of KD foods, regular social education and finally consideration of peer mentoring.

ABSTRACT

The classic ketogenic diet is an effective treatment option for drug-resistant epilepsy, but its high fat content challenges patient compliance. Optimizing liver ketone production guided by a method comparing substrates for their ketogenic potential may help to reduce the fat content of the diet without loss in ketosis induction. Here, we present a liver cell assay measuring the ß-hydroxybutyrate (ßHB) yield from fatty acid substrates. Even chain albumin-conjugated fatty acids comprising between 4 and 18 carbon atoms showed a sigmoidal concentration-ßHB response curve (CRC) whereas acetate and omega-3 PUFAs produced no CRC. While CRCs were not distinguished by their half-maximal effective concentration (EC50), they differed by maximum response, which related inversely to the carbon chain length and was highest for butyrate. The assay also suitably assessed the ßHB yield from fatty acid blends detecting shifts in maximum response from exchanging medium chain fatty acids for long chain fatty acids. The assay further detected a dual role for butyrate and hexanoic acid as ketogenic substrate at high concentration and ketogenic enhancer at low concentration, augmenting the ßHB yield from oleic acid and a fatty acid blend. The assay also found propionate to inhibit ketogenesis from oleic acid and a fatty acid blend at low physiological concentration. Although the in vitro assay shows promise as a tool to optimize the ketogenic yield of a fat blend, its predictive value requires human validation.

ABSTRACT

Ketogenic dietary therapies (KDT) are diets that induce a metabolic condition comparable to fasting. All types of KDT comprise a reduction in carbohydrates whilst dietary fat is increased up to 90% of daily energy expenditure. The amount of protein is normal or slightly increased. KDT are effective, well studied and established as non-pharmacological treatments for pediatric patients with refractory epilepsy and specific inherited metabolic diseases such as Glucose Transporter Type 1 Deficiency Syndrome. Patients and caregivers have to contribute actively to their day-to-day care especially in terms of (self-) calculation and (self-) provision of dietary treatment as well as (self-) measurement of blood glucose and ketones for therapy monitoring. In addition, patients often have to deal with ever-changing drug treatment plans and need to document occurring seizures on a regular basis. With this review, we aim to identify existing tools and features of telemedicine used in the KDT context and further aim to derive implications for further research and development.

ABSTRACT

The ketogenic diet (KD), characterized by high-fat and low-carbohydrate intake, is currently gaining widespread popularity as a treatment for drug-resistant epilepsy (DRE). In addition to the traditional ketogenic diet, several variants have been introduced to enhance compliance and flexibility, such as the modified Atkins diet (MAD) and the low glycemic index diet (LGID). These adaptations aim to provide patients with more manageable and sustainable options while harnessing the potential therapeutic benefits of DRE. The objective of this study is to evaluate the efficacy and safety of the KD in pediatric patients who exhibit DRE. In this study, we conducted a thorough review of existing literature by searching Cochrane, Embase, Medline, and PubMed. Our approach involved predefined criteria for data extraction and the assessment of study quality. Eleven RCTs with 788 participants were included in this study. The pooled effect estimates revealed a significant association between dietary interventions and seizure frequency reduction of > 50% (OR 6.68, 96% CI 3.52, 12.67) and > 90% (OR 4.37, 95% CI 2.04, 9.37). Dietary interventions also increased the odds of achieving seizure freedom (OR 4.13, 95% CI 1.61, 10.60). The common adverse effects included constipation (39.07%) and vomiting (10%). In conclusion, dietary interventions, notably the KD, hold promise for pediatric DRE, reducing seizures and achieving freedom. These non-pharmacological options improve the quality of life of non-responsive and non-surgical patients. The KD has emerged as a potential therapeutic approach. Further research is needed to address the limitations and investigate their long-term effects.

ABSTRACT

BACKGROUND: The ketogenic diet may be difficult for some patients and their families to implement and can impact physical, emotional, and social well-being. METHODS: Through principles of fundamental qualitative description, we completed an exploratory study on parents' experiences and expectations on the use and efficacy of the ketogenic diet for children with medically refractory epilepsy. RESULTS: Seventeen parents (10 mothers and 7 fathers) of 12 children with epilepsy participated. At the time of the interview, parents had experienced an average of 25 months of ketogenic diet treatment for their child (range 2 months to 98 months). Half of the caregivers learned about the ketogenic diet from their neurologist, whereas the remainder had heard about it from another source (ie, the internet). Most caregivers' (n = 13) diet expectations were related to seizure control. However, child development (n = 5) and quality of life (n = 5) were also crucial to some. Physical impacts of the diet were most commonly gastrointestinal for children (n = 9). Social and emotional effects were noted in some older children with typical development. Most caregivers described negative impacts on finances (n = 15), relationships (n = 14), and emotional well-being (ie, stress) (n = 12). Caregivers benefited from the ketogenic diet team's regular communication, close follow-up, and family-centered care. CONCLUSIONS: Despite the impacts that the ketogenic diet may have on caregivers' emotional and social well-being, the positive impacts of the diet were felt to outweigh any perceived risks. Effects (both positive and negative) on quality of life and child development (eg, social, emotional, cognitive) are essential for caregivers and require additional investigation.

ABSTRACT

BACKGROUND: Research has shown gene ATN1 to be associated with the nuclear receptor signaling. Its mutations in an evolutionarily conserved histidine-rich motif may cause CHEDDA, short for congenital hypotonia, epilepsy, developmental delay and digital anomalies, a recently identified neurodevelopmental syndrome that could evolve into developmental and epileptic encephalopathy (DEE). Up to date, there have been reported less than 20 cases, whose clinical features and treatment are worth in-depth exploring. METHODS: The clinical characteristics and genetic data of an infant with CHEDDA and further DEE were analyzed, who carried a de novo ATN1 variant identified by trio whole-exome sequencing. The alike patients with such a neurodevelopmental syndrome and epileptic seizures were reviewed on the literature. RESULTS: The infant harboring a de novo missense mutation in ATN1 (c.3155A>C; p.His1052Pro) held almost all features of CHEDDA and presented with drug-resistant epileptic spasms, differing from one case previously reported with the same gene variant exhibiting milder seizures controlled easily. We further reviewed 11 CHEDDA patients with epileptic seizures in the literature and compared the correlation between abnormal cerebral structure and the incidence of intractable epilepsy among CHEDDA patients. Fortunately, this patient's seizures decreased remarkably after administering ketogenic diet (KD). CONCLUSION: CHEDDA patients have significant phenotypic differences, especially in the epilepsy severity and their drug resistance, even if they carry the same mutation hotspot. Ketogenic diet and other treatments like Topiramate should be recommended for ATN1-related refractory epilepsy based on their regulation on expression of cation-chloride cotransporters and cellular hyperpolarization.

ABSTRACT

BACKGROUND: A core outcome set defines the minimum outcomes that should be included in clinical trials, audit or practice. The aim being to increase the quality and relevance of research by ensuring consistency in the measurement and reporting of outcomes. Core outcome sets have been developed for a variety of disease states and treatments. However, there is no established set of core outcomes for refractory childhood epilepsy treated with ketogenic diet therapy. This should be developed using a patient-centred approach to ensure the outcomes measured are relevant to patients and clinical practice. METHODS: This is a mixed methods study of four phases to develop a core outcome set for refractory childhood epilepsy treated with ketogenic diet therapy. In phase 1, a systematic scoping review of the literature will establish which outcomes are measured in trials of refractory epilepsy treated with ketogenic diet therapy. In phase 2, qualitative interviews with parents and carers will aim to identify the outcomes of importance to these stakeholders. Phase 3 will see a comprehensive list of outcomes collated from the first two phases, grouped into domains according to an outcome taxonomy. Phase 4 will invite parents, health care professionals and researchers to participate in a two-round Delphi study to rate the importance of the presented outcomes. Following which, the core outcome set will be ratified at a face to face consensus meeting. DISCUSSION: This study will guide outcome measurement in future studies of childhood epilepsy treated with ketogenic diet therapy and clinical practice through audit and service evaluation.

ABSTRACT

PURPOSE: Ketogenic diet (KD) is a well-established nonpharmacologic treatment for drug-resistant epilepsy. However, although KD has a long history of clinical use, there are still many difficulties with its real-world practice. This study retrospectively described the situation of KD practice in two children's hospitals in Southwest China. METHODS: We reviewed and analyzed clinical data collected at the baseline, and during follow ups at 1, 3, 6, 12, 18, and 24 months. The patient retention, the efficacy, side effects of KD, and the reasons for discontinuation were focused. RESULTS: There was increasing availability of KD for children with epilepsy in Southwest China and its effectiveness in controlling seizures was reconfirmed. Nonetheless, less than half of the patients adhered to KD for one year and about 1/5 of the patients for two years. Unsatisfactory seizure control was the most common reason for discontinuation, followed by patient/caregiver preference, acute infection, and loss to follow up. Adverse effects were mostly tolerable and not the main reason for discontinuation. Meanwhile, KD showed negative impacts on linear growth, and our cohort seemed to have more infections and deaths. CONCLUSIONS: Despite increasing availability and good efficacy, long-term adherence to KD was difficult. Compliance issues appeared to be prominent. Enhancing food taste and patient support can help to improve the retention rate.

ABSTRACT

BACKGROUND: Changes in adipokine secretion may be involved in the anti-epileptic effect of a ketogenic diet (KD) in drug-resistant epilepsy (DRE). OBJECTIVES: The assessment of the influence of KD on serum adiponectin, omentin-1, and vaspin in children with DRE. METHODS: Anthropometric measurements (weight, height, BMI, and waist-to-hip circumference ratio) were performed in 72 children aged 3-9 years, divided into 3 groups: 24 children with DRE treated with KD, 26-treated with valproic acid (VPA), and a control group of 22 children. Biochemical tests included fasting glucose, insulin, beta-hydroxybutyric acid, lipid profile, aminotransferases activities, and blood gasometry. Serum levels of adiponectin, omentin-1 and vaspin were assayed using commercially available ELISA tests. RESULTS: Serum levels of adiponectin and omentin-1 in the KD group were significantly higher and vaspin-lower in comparison to patients receiving VPA and the control group. In all examined children, serum adiponectin and omentin-1 correlated negatively with WHR and serum triglycerides, insulin, fasting glucose, and HOMA-IR. Vaspin levels correlated negatively with serum triglycerides and positively with body weight, BMI, fasting glucose, insulin, and HOMA-IR. CONCLUSION: One of the potential mechanisms of KD in children with drug-resistant epilepsy may be a modulation of metabolically beneficial and anti-inflammatory adipokine levels.

ABSTRACT

Background: Ketogenic dietary therapies (KDT) are used as a treatment in childhood epilepsy. However, their mechanism has not yet been established. The main objective of this study was to determine the changes in the transcriptomic profile induced by KDT in children with epilepsy in order to shed light on its possible mechanisms. Methods: Eight children with refractory epilepsy were enrolled in the study. Peripheral blood mononuclear cells were obtained before and after the children were treated with KDT for a minimum of 6 months. RNA was extracted and mRNA and miRNA profiling were performed and analyzed. Results: Our intervention with KDT significantly reduced the seizure number in seven of the eight paediatric patients treated and caused important changes in their gene expression profile. Our study reveals modifications in the transcription of 4630 genes and 230 miRNAs. We found that the genes involved in the protection against epileptic crises were among those mainly changed. These genes collectively encode for ion channels, neurotransmitter receptors, and synapse structural proteins. Conclusions: Together our results explain the possible mechanisms of KDT and reinforce its clinical importance in the treatment of epilepsy.

ABSTRACT

The ketogenic diet (KD) is a high-fat, adequate-protein, and very-low-carbohydrate diet regimen that mimics the metabolism of the fasting state to induce the production of ketone bodies. The KD has long been established as a remarkably successful dietary approach for the treatment of intractable epilepsy and has increasingly garnered research attention rapidly in the past decade, subject to emerging evidence of the promising therapeutic potential of the KD for various diseases, besides epilepsy, from obesity to malignancies. In this review, we summarize the experimental and/or clinical evidence of the efficacy and safety of the KD in different diseases, and discuss the possible mechanisms of action based on recent advances in understanding the influence of the KD at the cellular and molecular levels. We emphasize that the KD may function through multiple mechanisms, which remain to be further elucidated. The challenges and future directions for the clinical implementation of the KD in the treatment of a spectrum of diseases have been discussed. We suggest that, with encouraging evidence of therapeutic effects and increasing insights into the mechanisms of action, randomized controlled trials should be conducted to elucidate a foundation for the clinical use of the KD.

ABSTRACT

BACKGROUND: Ketogenic diet (KD) is widely used for drug-resistant epilepsy (DRE). The study was designed to evaluate one of the risk factors for development of renal calculi with KD. METHODS: Twenty patients with DRE on Modified Atkins diet (MAD) were subjected to full history and laboratory investigations, including microscopic urine analysis, urinary calcium after overnight fasting, and calcium/creatinine ratio, as well as pelviabdominal ultrasound. Frequency and severity of seizures assessed by Chalfont severity score were recorded. All assessment measures were repeated after 3 and 6 months of KD therapy. RESULTS: There were significant reductions in both frequency and severity of seizures, yet 2 patients (10%) developed renal stones after 6 months on KD. Gross hematuria was reported in 1 of those 2 patients (50%), but microscopic hematuria was detected in both patients. The urine calcium and the urine calcium/creatinine ratio were elevated in both patients having renal calculi after 6 months. CONCLUSIONS: KD increases the risk of renal stones with hypercalciuria among the causes. We recommend initiation of prophylactic measures once KD is commenced by maximizing fluid intake and urine alkalinization with regular urinary studies including calcium/creatinine ratio and renal ultrasound for patients with symptoms. IMPACT: KD has been increasingly used in epilepsy management and beyond. The potential side effects of such diet should be highlighted while valuing the merits. KD increases the risk of renal stones because of hypercalciuria among other causes. We recommend initiation of prophylactic measures once KD is commenced by maximizing fluid intake and urine alkalinization with estimation of urinary calcium/creatinine ratio and renal ultrasound in patients with relevant symptoms.

ABSTRACT

Introducción: la dieta cetogénica (CD) es un tratamiento no farmacológico efectivo, ya establecido para la epilepsia refractaria en la infancia. Objetivo: el objetivo de este estudio fue comparar la eficacia, la presencia de efectos indeseables y la adherencia entre la dieta cetogénica clásica (DCC) y la dieta de Atkins modificada (DAM).Materiales y métodos: se realizó una investigación retrospectiva y comparativa, evaluando las historias clínicas de todos los pacientes que iniciaron tratamiento con dieta cetogénica a cargo de un mismo equipo de trabajo entre 2008 y 2018. Se incluyeron 57 pacientes que iniciaron una dieta DAM y 19 pacientes con dieta DCC. Resultados: se observó que tanto la dieta Atkins como la clásica fueron igualmente eficaces (80 %, aproximadamente; p = 0,252). En relación a la adherencia, se registró un porcentaje significativamente mayor de adherencia a la dieta Atkins que a la clásica (p = 0,018). Se observaron menos efectos adversos con la DAM que con la dieta CC (p = 0,012). El 21 % de los pacientes con DAM presentaron efectos desfavorables (12/57), mientras que el 52.63 % de los pacientes en DCC tuvieron complicaciones (10/19). Conclusión: se describe una efectividad equiparable en cuanto al control de crisis entre la DAM y la DCC. Sin embargo, la DAM presenta una adherencia mucho mejor que la observada con la DCC y sus efectos indeseables son más leves y más infrecuentes. Es por eso que, de acuerdo con otros trabajos, la DAM probablemente sea la primera elección para los pacientes con epilepsia refractaria en un gran porcentaje de los casos. (AU)


Background: the ketogenic diet (CD) is an established, effective non-pharmacological treatment for refractory epilepsy in childhood. Aim: the objective of this study was to compare the efficacy, the presence of undesirable effects, and adherence between the classic ketogenic diet (DCC) and the modified Atkins diet (DAM). Materials and methods: a retrospective and comparative investigation was carried out to evaluate the medical records of all the patients who started treatment with a ketogenic diet by the same team between 2008 and 2018. In all, 57 patients were started on a DAM diet and 19 patients were given a DCC diet. Results: it was observed that both the Atkins and the classic diets were equally effective (approximately, 80 %; p = 0.252). Regarding adherence, there was a significantly higher percentage of adherence to the Atkins diet than to the classic diet (p = 0.018). Fewer adverse effects were observed with DAM than with DCC (p = 0.012). In all, 21 % of patients under DAM had unfavorable effects (12/57), while 52.63 % of patients on DCC had complications (10/19). Conclusion: a comparable effectiveness in terms of crisis control was found between DAM and DCC. However, DAM exhibits a much better adherence than DCC, and its undesirable effects are milder, less common. That is why, according to other works, it is likely that DAM should be first-choice for patients with refractory epilepsy in a large percentage of cases. (AU)

ABSTRACT

Medical ketogenic diets (KDs) are effective yet resource-intensive treatment options for drug-resistant epilepsy (DRE). We investigated dietetic care contact time, as no recent data exist. An online survey was circulated to ketogenic dietitians in the UK and Ireland. Data were collected considering feeding route, KD variant and type of ketogenic enteral feed (KEF), and the estimated number of hours spent on patient-related activities during the patient journey. Fifteen dietitians representing nine KD centres responded. Of 335 patients, 267 (80%) were 18 years old or under. Dietitians spent a median of 162 h (IQR 54) of care contact time per patient of which a median of 48% (IQR 6) was direct contact. Most time was required for the classical KD taken orally (median 193 h; IQR 213) as a combined tube and oral intake (median 211 h; IQR 172) or a blended food KEF (median 189 h; IQR 148). Care contact time per month was higher for all KDs during the three-month initial trial compared to the two-year follow-up stage. Patients and caregivers with characteristics such as learning or language difficulties were identified as taking longer. Twelve out of fifteen (80%) respondents managed patients following the KD for more than two years, requiring an estimated median contact care time of 2 h (IQR 2) per patient per month. Ten out of fifteen (67%) reported insufficient official hours for dietetic activities. Our small survey gives insight into estimated dietetic care contact time, with potential application for KD provision and service delivery.

ABSTRACT

BACKGROUND: Neurological manifestations are commonly reported in patients with celiac disease (CD). We aimed to characterize epilepsy features in a pediatric population with CD and the effect of a gluten-free diet (GFD) on seizure burden. METHODS: A retrospective chart review was performed on pediatric patients treated at the University of Utah and Primary Children's Hospital in Salt Lake City, Utah, with both epilepsy and CD and compared with a control group with epilepsy only. RESULTS: We identified 56 patients with epilepsy and biopsy-confirmed CD (n = 36, 64%) or elevated tissue transglutaminase antibodies (tTG-Ab) without biopsy-confirmed CD (n = 20, 36%). Age- and gender-matched controls were selected from patients with epilepsy only (n = 168). Patients with biopsy-proven CD or positive tTG-Ab had high percentage of drug-resistant epilepsy (DRE) compared with the control group (P < 0.05). Age at seizure onset preceded the diagnosis of CD on average by 5.9 years for patients with DRE (P < 0.01) compared with 2.2 years for those with drug-responsive epilepsy. Adhering to a GFD reduced seizure frequency or resulted in weaning dosage or weaning off of one or more antiseizure medications in a majority of patients with DRE. CONCLUSIONS: DRE was more prevalent in pediatric patients with biopsy-confirmed CD and positive tTG-Ab compared with the control group (which included childhood epilepsy syndromes), but comparable with the prevalence of DRE in the general population. Adherence to a GFD in combination with antiseizure medications appears to reduce seizure burden for those with CD and DRE.
