Feasibility, Tolerability and Efficacy of the Ketogenic Diet in Children With Drug-resistant Epilepsy in South Vietnam

January 15, 2023 updated by: Thuy-Minh-Thu NGUYEN, Number 2 Children's Hospital, Ho Chi Minh City
According to the World Health Organization, more than 50 million people have epilepsy. Among them, nearly 80% of epileptic patients live in developing countries and 75% of them do not have access to treatment. The ketogenic diet (KD) has been shown as an effective alternative for patients with drug-resistant epilepsy. Although it has been studied by few studies in Asia, no such studies have been conducted in Vietnam. The purpose of this study was to verify the feasibility, tolerability, and efficacy of the KD in children with refractory epilepsies followed at a pediatric center in South Vietnam.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Children with drug-resistant epilepsy followed at Children's Hospital No.2, Viet Nam treated by KD were included in a prospective study from June 2019 to October 2021. Side-effects, retention rate, number, and duration of seizures were recorded after 1, 3, 6, 9, and 12 months of KD. Patients were considered as responders when a 50% seizure frequency was reached. Tolerance and acceptability of the KD were closely monitored.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

1 year to 10 years (Child)

Accepts Healthy Volunteers

No

Genders Eligible for Study

  • age from 1 to 10 years at the time of enrolment,
  • drug-resistant epilepsy according to the 2010 ILAE criteria,
  • an indication for a ketogenic diet trial according to the 2018 ILAE recommendations

Exclusion Criteria:

Experimental: The feasibility of the ketogenic diet
The purpose of this study was to verify the feasibility of the ketogenic diet in children with refractory epilepsies followed at a pediatric center in South Vietnam. The patient was considered feasible if he (or she) did not have the contra-indication for the ketogenic diet
Dietary supplement: Ketogenic diet

Experimental: the tolerability of the ketogenic diet
The purpose of this study was to verify the tolerability of the ketogenic diet in children with refractory epilepsies followed at a pediatric center in South Vietnam. The patient was considered tolerant if he (or she) did not have any side effects caused by the ketogenic diet
