Ketogenic diet in Zambia: Managing drug-resistant epilepsy in a low and middle income country.

ABSTRACT: Globally, drug-resistant epilepsy affects one third of people living with epilepsy. With limitations in treatment options for refractory epilepsy in resource-limited regions, ketogenic diet therapy is an important option to consider. Utilizing the 2015 International League Against Epilepsy recommended minimum requirements for ketogenic diet therapy, three male children with refractory epilepsy, aged 2.5, 6.5 and 10?years, were initiated on the classical ketogenic diet using locally available food in August 2017 at University Teaching Hospitals-Children's Hospital in Lusaka, Zambia, through partnership with the Epilepsy Program at Boston Children's Hospital in the United States. Following successful initiation in all three children, the diet was discontinued in the 10-year-old due to difficulties complying with the diet. The youngest child demonstrated an over 50% seizure reduction and gained developmental milestones. The third child achieved seizure freedom and showed marked improvement in behaviour. This pilot demonstrates the feasibility of ketogenic diet as an important therapeutic option for refractory epilepsy in Zambia. Given the limitations in treatment choices and medication accessibility, dietary therapy offers an alternative management strategy in our setting. Collaboration with an established ketogenic diet centre contributes to a successful program.

Project description:ObjectiveTuberous sclerosis complex (TSC) is a rare disease with a high risk of epilepsy and cognitive impairment in children. Ketogenic diet (KD) therapy has been consistently reported to be beneficial to TSC patients. In this study, we aimed to investigate the efficacy and safety of KD in the treatment of drug-resistant epilepsy and cognitive impairment in children with TSC.MethodsIn this multicenter study, 53 children (33 males and 20 females) with drug-resistant epilepsy or cognitive impairment caused by TSC were retrospectively recruited from 10 hospitals from January 1, 2010, to December 31, 2020. Intention-to-treat analysis was used to evaluate seizure reduction and cognition improvement as outcomes after KD therapy.ResultsOf the 53 TSC patients included, 51 failed to be seizure-free with an average of 5.0 (range, 4-6) different anti-seizure medications (ASMs), before KD therapy. Although the other two patients achieved seizure freedom before KD, they still showed psychomotor development delay and electroencephalogram (EEG) abnormalities. At 1, 3, 6, and 12 months after the KD therapy, 51 (100%), 46 (90.2%), 35 (68.6%), and 16 patients (31.4%) remained on the diet therapy, respectively. At these time points, there were 26 (51.0%), 24 (47.1%), 22 (43.1%) and 13 patients (25.5%) having ≥50% reductions in seizure, including 11 (21.6%), 12 (23.5%), 9 (17.6%) and 3 patients (5.9%) achieving seizure freedom. In addition, of 51 patients with psychomotor retardation, 36 (36 of 51, 70.6%) showed cognitive and behavioral improvements. During the KD therapy, no serious side effects occurred in any patient. The most common side effects were gastrointestinal disturbance (20 of 53, 37.7%) and hyperlipidemia (6 of 53, 11.3%). The side effects were gradually relieved after adjustment of the ketogenic ratio and symptomatic treatment.ConclusionKD is an effective and safe treatment for TSC-related drug-resistant epilepsy and cognitive impairment in children. KD can reduce seizure frequency and may potentially improve cognition and behavior.

Project description:ImportanceThe ketogenic diet (KD) has been used successfully to treat children with drug-resistant epilepsy. Data assessing the efficacy of the modified Atkins diet (MAD) and low glycemic index therapy (LGIT) diet compared with the KD are scarce.ObjectiveTo determine whether the MAD and LGIT diet are noninferior to the KD among children with drug-resistant epilepsy.Design, setting, and participantsOne hundred seventy children aged between 1 and 15 years who had 4 or more seizures per month, had not responded to 2 or more antiseizure drugs, and had not been treated previously with the KD, MAD, or LGIT diet were enrolled between April 1, 2016, and August 20, 2017, at a tertiary care referral center in India.ExposuresChildren were randomly assigned to receive the KD, MAD, or LGIT diet as additions to ongoing therapy with antiseizure drugs.Main outcomes and measuresPrimary outcome was percentage change in seizure frequency after 24 weeks of dietary therapy in the MAD cohort compared with the KD cohort and in the LGIT diet cohort compared with the KD cohort. The trial was powered to assess noninferiority of the MAD and LGIT diet compared with the KD with a predefined, noninferiority margin of -15 percentage points. Intention-to-treat analysis was used.ResultsOne hundred fifty-eight children completed the trial: KD (n = 52), MAD (n = 52), and LGIT diet (n = 54). Intention-to-treat analysis showed that, after 24 weeks of intervention, the median (interquartile range [IQR]) change in seizure frequency (KD: -66%; IQR, -85% to -38%; MAD: -45%; IQR, -91% to -7%; and LGIT diet: -54%; IQR, -92% to -19%) was similar among the 3 arms (P = .39). The median difference, per intention-to-treat analysis, in seizure reduction between the KD and MAD arms was -21 percentage points (95% CI, -29 to -3 percentage points) and between the KD and LGIT arms was -12 percentage points (95% CI, -21 to 7 percentage points), with both breaching the noninferiority margin of -15 percentage points. Treatment-related adverse events were similar between the KD (31 of 55 [56.4%]) and MAD (33 of 58 [56.9%]) arms but were significantly less in the LGIT diet arm (19 of 57 [33.3%]).Conclusions and relevanceNeither the MAD nor the LGIT diet met the noninferiority criteria. However, the results of this study for the LGIT diet showed a balance between seizure reduction and relatively fewer adverse events compared with the KD and MAD. These potential benefits suggest that the risk-benefit decision with regard to the 3 diet interventions needs to be individualized.Trial registrationClinicalTrials.gov Identifier: NCT02708030.

Project description:ObjectiveTo investigate incorporating a ready-to-use 2.5:1 ratio liquid feed into a ketogenic diet (KD) in children and adults with drug-resistant epilepsy.MethodsFollowing a three-day baseline, patients (n = 19; age: 19 years [SD 13], range: 8-46 years) followed a KD for 28 days (control period), then incorporated ≥200 mL/day of a ready-to-use liquid feed, made with a ratio of 2.5 g of fat to 1 g of protein plus carbohydrate and including medium chain triglycerides ([MCTs]; 25.6% of total fat/100 mL) for 28 days as part of their KD (intervention period). Outcome measures (control vs intervention period) included gastrointestinal (GI) tolerance, adherence to KD and intervention feed, dietary intake, blood ß-hydroxybutyrate (BHB) concentration, seizure outcomes, health-related quality of life (HRQoL), acceptability and safety.ResultsCompared to the control period, during the intervention period, the percentage of patients reporting no GI symptoms increased (+5% [SD 5], p = 0.02); adherence to the KD prescription was similar (p = 0.92) but higher in patients (n = 5) with poor adherence (<50%) to KD during the control period (+33% [SD 26], p = 0.049); total MCT intake increased (+12.1 g/day [SD 14.0], p = 0.002), driven by increases in octanoic (C8; +8.3 g/day [SD 6.4], p < 0.001) and decanoic acid (C10; +5.4 g/day [SD 5.4], p < 0.001); KD ratio decreased (p = 0.047), driven by a nonsignificant increase in protein intake (+11 g/day [SD 44], p = 0.29); seizure outcomes were similar (p ≥ 0.63) but improved in patients (n = 6) with the worst seizure outcomes during the control period (p = 0.04); and HRQoL outcomes were similar. The intervention feed was well adhered to (96% [SD 8]) and accepted (≥88% of patients confirmed).SignificanceThese findings provide an evidence-base to support the effective management of children and adults with drug-resistant epilepsy following a KD with the use of a ready-to-use, nutritionally complete, 2.5:1 ratio feed including MCTs.Plain language summaryThis study examined the use of a ready-to-use, nutritionally complete, 2.5:1 ratio (2.5 g of fat to 1 g of protein plus carbohydrate) liquid feed, including medium chain triglycerides (MCTs), into a ketogenic diet (KD) in children and adults with drug-resistant epilepsy. The results show that the 2.5:1 ratio feed was well tolerated, adhered to, and accepted in these patients. Increases in MCT intake (particularly C8 and C10) and improvements in seizure outcomes (reduced seizure burden and intensity) and KD adherence also occurred with the 2.5:1 ratio feed in patients with the worst seizures and adherence, respectively.
