ABSTRACT
INTRODUCTION: Drug-resistant epilepsy presents high worldwide prevalence and is difficult to control despite the wide variety of available antiepileptic drugs (AED). The modified Atkins diet (MAD) is an additional treatment alternative. Several studies have addressed the use of the ketogenic diet and MAD in children with drug-resistant epilepsy, but insufficient research has been conducted into adults with the same condition. OBJECTIVE: To evaluate the effectiveness and tolerability of, and adherence to, the MAD in adults with drug-resistant epilepsy. MATERIAL AND METHODS: We conducted a 6-month pre-post prospective study at a reference hospital. Patients were prescribed the MAD with limited carbohydrate intake and unlimited fat intake. We conducted clinical and electroencephalographic follow-up according to the relevant guidelines, and assessed adverse effects changes in laboratory findings, and adherence. RESULTS: Thirty-two patients with drug-resistant epilepsy were included in the study. Patients' mean age was 30 years, mean disease progression time was 22 years, and all patients had focal or multifocal epilepsy. Thirty-four percent of patients presented >â¯50% decreases in overall seizure frequency (Pâ¯=â¯â¯.001); seizure control was greater in the first month and subsequently declined. These patients presented weight loss (RR: 7.2; 95% CI, 1.3-39.5; P = .02), good to fair adherence only in the first and third months (RR: 9.4; 95% CI, 0.9-93.6; Pâ¯=â¯.04 and RR: 0.4; 95% CI, 0.30-0.69; Pâ¯=â¯.02, respectively). Tolerability data showed that the MAD is safe: adverse effects were minor and short-lived in most cases, with the exception of mild to moderate hyperlipidaemia in one-third of patients. The adherence rate was 50% at the end of the study. CONCLUSIONS: In adults with drug-resistant focal epilepsy, the MAD showed adequate tolerability and moderate but decreasing effectiveness and adherence, probably due to a preference for a carbohydrate-based diet.
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)

La dieta de Atkins modificada (DAM) es una alternativa dietaria terapéutica en el tratamiento de la epilepsia fármaco-resistente. Consiste en una dieta con un aporte de 60% de grasas, 30% de proteínas y 10% de carbohidratos. El objetivo es presentar una serie de 9 pacientes con diagnóstico de epilepsia refractaria de diferentes etiologías, que recibieron tratamiento con DAM en nuestro hospital. En nuestro grupo de 9 pacientes, obtuvimos resultados similares a los publicados por otros autores, con buena adherencia, tolerancia y respuesta. Del total de pacientes, dos lograron una reducción en más del 90% del número de crisis; cuatro, del 50-90%; dos, menos del 50% de control; y solo uno no presentó respuesta a la DAM. Ningún paciente presentó aumento del número de crisis, y fue bien tolerada en todos los casos

INTRODUÇÃO: A dieta cetogênica (DC) e a dieta de Atkins modificada (DAM) são dietas terapêuticas mundialmente utilizadas no tratamento da epilepsia refratária em crianças e adultos. No Brasil estas modalidades de tratamento são pouco indicadas, restringindo a poucos centros. METODOLOGIA: Revisão de literatura sobre a utilização da DC e DAM no tratamento da epilepsia refratária. CONCLUSÕES: A DC e a DAM são opções terapêuticas eficazes e seguras no tratamento da epilepsia refratária. O acompanhamento destes pacientes deve ser rigoroso, com equipe treinada, prevendo os riscos potenciais e realizando dietas palatáveis e diversificadas.
INTRODUCTION: Ketogenic Diet (KD) and Modified Atkins Diet (MAD) are world-widely therapeutic diets used in the treatment of intractable epilepsy in children and adults. In Brazil those therapies are few indicated and restricted for some centers. METHODS: Revision of literature for the application of KD and MAD in the treatment of intractable epilepsy. CONCLUSIONS: KD and MAD are effective and secure in the treatment of intractable epilepsy. The follow up of these patients must be rigorous, with a trained staff to anticipate the potential risks and elaborating diversified and palatable diets.
