Modified Atkins diet versus levetiracetam for non-surgical drug-resistant epilepsy in children: A randomized open-label study.

BACKGROUND: This study was undertaken to compare the efficacy of modified Atkins diet (MAD) among children with non-surgical drug-resistant epilepsy (DRE) to levetiracetam, when added to on-going anti-seizure medications. METHODS: An open-label, randomized controlled trial among children aged 2-12 years with non-surgical DRE was conducted. Eligible children were randomized in a 1:1 ratio to receive add-on MAD or levetiracetam. Baseline and post-intervention seizure frequency at 12 weeks was determined from seizure logs maintained by parents. The primary outcome was the proportion of responders, i.e., patients who achieved > 50% seizure reduction from baseline. Adverse events were compared. Analysis was intention-to-treat. (NCT04172311) RESULTS: One hundred and one children were enrolled (MAD-51, levetiracetam-50). The majority of the enrolled children had generalized seizures of mixed types secondary to structural brain lesions and Lennox-Gastaut syndrome was the most common electroclinical syndrome (46%). The proportion of children with >50% seizure reduction at 12 weeks was significantly higher in the MAD arm compared to the levetiracetam arm (27/51(52.9%) vs 11/50(22%); p < 0.001). At 12-weeks post-intervention, the change in mean seizure frequency compared to baseline was -47.33 ± 39.57% in the MAD arm and -31.15 ± 32.18% in the levetiracetam arm (p = 0.03). Constipation (41.1%) was the most frequent adverse effect with MAD. Sedation/lethargy (18%) and anxiety and irritability (14%) were the most frequent adverse effects in the levetiracetam group. CONCLUSION: Addition of MAD was found to be superior to levetiracetam among children with non-surgical DRE with predominant generalized seizures in achieving seizure reduction at 12 weeks. Both treatments were well tolerated. Adverse effects, although higher with MAD, were expected side effects.

Evaluation of the Modified Atkins Diet for the Treatment of Epileptic Spasms Refractory to Hormonal Therapy: A Randomized Controlled Trial.

OBJECTIVES: We aimed to evaluate the efficacy of the modified Atkins diet in children with epileptic spasms who had failed hormonal therapy. METHODS: Children aged 9 months to 3 years having daily epileptic spasms despite a trial of ACTH or oral prednisolone and 1 additional anticonvulsant medication were enrolled. Children were randomly assigned to receive the modified Atkins diet either immediately or after a delay of 4 weeks. The ongoing anticonvulsant medications were continued unchanged. The primary outcome variable was the proportion of children who achieved spasm freedom as per parental reports at 4 weeks. Secondary outcomes included time to spasm cessation, proportion of children with electroclinical remission, the proportion of children with >50% reduction of spasms at 4 weeks, and adverse effects of the diet. (ClinicalTrials.gov Identifier: NCT03807141). RESULTS: A total of 91 children were enrolled in the study; 46 in the diet group and 45 in the control group. At the end of 4 weeks, 11 children in the diet group were spasm free compared with none in the control group (P ≤ .001). The median time to achieve spasm cessation was 10 days (interquartile range 9-20). Nine of these had resolution of hypsarrhythmia on electroencephalography (EEG). Thirty (65.2%) in the diet group had >50% reduction in spasms, compared with none in the control group (P < .001). The most common side effect was constipation, noted in 34.8% of the children. CONCLUSIONS: The modified Atkins diet was found to be effective and well tolerated in children with epileptic spasms refractory to hormonal therapy.

Efficacy and tolerability of the modified Atkins diet in young children with refractory epilepsy: Indian experience.

BACKGROUND: The modified Atkins diet (MAD) has been used predominantly in older children, adolescents, and adults. There is a paucity of data on the use of the MAD in refractory epilepsy in young children. OBJECTIVES: This study was planned to evaluate the efficacy and tolerability of the MAD in refractory epilepsy in young children. METHODS: This study recruited children aged 9 months to 3 years with refractory seizures. Children received MAD for 6-month with the on-going anticonvulsant medications being continued unchanged. Reduction in seizure frequency was the primary outcome measure. Adverse effects were also studied. RESULTS: Thirty-one children with daily seizures were studied with a median age of 18-month (range 9-30 months). West syndrome was the most common epilepsy syndrome (26, 86.6%). Twenty-one children remained on diet at 3 months and 13 at 6 months. The children who achieved >50% seizure reduction were 17 (54.8%) at 3 months and 9 (29%) at 6 months. Refusal to eat was a significant problem seen in eight children. Three children discontinued the diet due to adverse effects. CONCLUSION: The MAD was found to be feasible, effective, and well-tolerated.

Efficacy and safety of oral triclofos as sedative for children undergoing sleep electroencephalogram: An observational study.

OBJECTIVES: Triclofos may be a better sedative in view of better palatability and less gastric irritation as compared to chloral hydrate. This study aimed to assess the efficacy of triclofos (a commonly used sedative in India) as a sedative for sleep electroencephalogram (EEG) study in children. METHODS: This prospective observational study was carried out in a tertiary care pediatric center. Consecutive children aged 6 months to 5 years referred for sleep EEG evaluation were recruited. Their clinical details were noted in a proforma after an informed consent. After a trial for natural sleep, oral triclofos was administered. Sleep parameters and adverse effects were noted. RESULTS: One-hundred and sixty children were then enrolled. EEG was successfully recorded in 149 (93.1%) children. Median latency of sleep onset was 30 min and median duration of sleep was 90 min. The adverse effects in the following 24 h were mild and included dizziness, irritability, and vomiting. CONCLUSIONS: Oral triclofos was found to be an effective sedative for EEG in children with minimal adverse effects.

Evaluation of a simplified modified Atkins diet for use by parents with low levels of literacy in children with refractory epilepsy: A randomized controlled trial.

PURPOSE: This study was planned to develop and evaluate a simple, easy-to-understand variation of the modified Atkins diet, for use by parents with low levels of literacy in children with refractory epilepsy. METHODS: This study was conducted in two phases. In the first phase, a simplified version of the modified Atkins diet was developed. In the second phase this was evaluated in children aged 2-14 years who had daily seizures despite the appropriate use of at least two anticonvulsant drugs, in an open-label randomized-controlled-trial. Children were randomized to receive either the simplified modified Atkins diet or no dietary intervention for a period of 3 months with the ongoing anticonvulsant medications being continued unchanged in both the groups. Reduction in seizure frequency was the primary outcome-measure. Data was analyzed using intention to treat approach. Adverse effects were also studied. (Clinical trial identifier NCT0189989). RESULTS: Forty-one children were randomly assigned to the diet-group, and 40 were assigned to the control-group. Two patients discontinued the diet during the study period. The proportion of children with>50% seizure reduction was significantly higher in the diet group as compared to the control group (56.1% vs 7.5%, p<0.0001). The proportion of children with 90% seizure reduction was also higher in the diet group (19.5% vs 2%, p=0.09). Six children in the diet group were seizure free at 3 months compared with two in the control group (p=0.26). At 3 months, 6 children had constipation and 5 had weight loss. CONCLUSION: A simplified version of the modified Atkins diet was developed for use by parents with low levels literacy. This diet was found to be feasible, efficacious and well tolerated in children with refractory epilepsy.
