Popis: Background and ObjectivesModified Atkins diet (MAD) has emerged as an adjuvant therapy in drug-resistant epilepsy (DRE). Most studies are in children; there is limited evidence for DRE in adults. This study aimed to investigate whether MAD along with standard drug therapy (SDT) was indeed more effective than SDT alone in reducing seizure frequency and improving psychological outcomes at 6 months in adolescents and adults with DRE (nonsurgical).MethodsA prospective randomized controlled trial was conducted at tertiary care referral center in India. Persons with DRE aged 10–55 years attending outpatient epilepsy clinics between August 2015 and April 2019, who had more than 2 seizures per month despite using at least 3 appropriate antiseizure medications (ASMs) at their maximum tolerated doses and had not been on any form of diet therapy for the past 1 year, were enrolled. Patients were assessed for the eligibility and randomly assigned to receive SDT plus MAD (intervention arm) or SDT alone (control arm). The primary outcome was >50% reduction in seizure frequency, and the secondary outcomes were quality of life (QOL), behavior, adverse events, and rate of withdrawal at 6 months. Intention-to-treat analysis was performed.ResultsA total of 243 patients were screened for eligibility; 160 patients (80 adults and 80 adolescents) were randomized to either the intervention or control arm. Demographic and clinical characteristics in both groups were comparable at baseline. At 6 months, >50% seizure reduction was seen in 26.2% in the intervention group vs 2.5% in the control group (95% CI 13.5–33.9;p< 0.001). Improvement in QOL was 52.1 ± 17.6 in the intervention group vs 42.5 ± 16.4 in the control group (mean difference, 9.6; 95% CI 4.3 to 14.9,p< 0.001). However, behavior scores could be performed in 49 patients, and improvement was seen in the intervention vs control group (65.6 ± 7.9 vs 71.4 ± 8.1,p= 0.015) at the end of the study. One patient had weight loss; 2 patients had diarrhea.DiscussionThe MAD group demonstrated improvement in all aspects (reduction in seizure frequency and behavioral problems) compared with the control group at the end of the study. MAD is an effective modality in controlling seizures; further research is required to assess its efficacy in terms of biomarkers along with descriptive metabolomics studies.Trial Registration InformationThe clinical trial registry of India: CTRI/2015/07/006048.Classification of EvidenceThis study provides Class III evidence that the MAD increases the probability of seizure reduction in adolescents and adults with DRE.
