About this study
Official title: Classic Ketogenic Diet and Modified: Evaluation of the Therapeutic Potential and Impact on the Oxidative Profile, Lipidomic, Inflammatory and Size of Lipoproteins in Children and Adolescents With Refractory Epilepsy
The ketogenic diet is a non-pharmacological treatment prescribed especially for children and indicated in most specialized centers for patients with refractory epilepsy. The composition of the ketogenic diet is based on high-fat, low-carbohydrate, moderate protein content, and the production of ketone bodies is the probable mechanism involved in the control of seizures. The relationship between the treatment of the ketogenic diet and changes in oxidative characteristics, physical and lipid are not well established. Some studies show a significant increase in total cholesterol and triglycerides in children being treated with ketogenic diet, but other studies have shown that changes in lipid profile in the long term do not appear to be significant, beyond the influence of these changes on coronary heart disease are unknown. The studies performed in the last two decades have shown that besides the changes in the lipid profile, oxidative modification of lipoproteins are essential for the initiation and progression of atherosclerosis and physical properties of lipoproteins also appear to be involved in this process, suggesting that the particle size of lipoproteins, through the analysis of subfractions can provide more details of the cardiovascular risk. Thus, this projetct aims to compare the effects of the classical ketogenic diet with the ketogenic diet modified with lower content of saturated fatty acids and a higher content of monounsaturated and polyunsaturated, the oxidative changes of LDL, lipidomic profile, the concentration of antioxidants in production inflammatory cytokines and the subfractions of LDL and HDL in children and adolescents with refractory epilepsy, the clinical effect on controlling epilepsy.
Read the detailed description
Controlled clinical trial composed of children of adolescents aged 1 to 19 years with refractory epilepsy drug polytherapy (antiepileptic drugs). Children of both sexes are being included. The control group receive the diet classical ketogenic while the case group receive the ketogenic diet modified reduction of at least 20% of the supply of saturated fat and increase> 50% of the acid supply monounsaturated fatty, increase> 50% of acid content polyunsaturated fatty and a lower ratio w6 / w3 at least 50% compared to classical diet used by the control group. Patients are followed in 3 times: baseline, 3 months and 6 months after the intervention.
Exclusion criteria: Children and adolescents who use any type of hormone replacement; Children and adolescents who present diagnosis of diabetes mellitus and hypothyroidism or hyperthyroidism; Children and adolescents with acute illnesses such as heart disease and kidney disease that prevent indication of the DC evaluated by medical history and complete physical examination by the neurologist doctor in charge of the clinic.
Outcome Measures:
- Characterize the sample as the demographics (gender, age), scioeconomic, quality of life and clinical; B. To assess dietary intake through food records; c. Evaluate the anthropometric profile and classify the nutritional status (Z score of body mass index for age [ZBMI / I]); d. Assess body composition (percentage of fat, lean mass, total body water and phase angle); e. Determine the concentration of cholesterol and triglycerides, lipoproteins (TC, TG, LDL and HDL); f. Determine the concentration of apolipoproteins: APOA-1 and APO-B; g. Detect the concentration of ketone bodies in the plasma (β-hydroxybutyrate); H. Detecting LDL (-) and oxidized LDL in plasma; i. To detect anti-LDL autoantibodies (-) and anti-oxLDL autoantibodies in plasma; j. Determine subfractions HDL, LDL and high LDL particle size; k. To evaluate the concentration of non-esterified fatty acids (NEFAs); l. Assess the concentration of fatty acids in plasma; m. To assess the concentration of substances reactive to thiobarbituric acid (TBARS) in plasma.
- Determine the concentration of antioxidants in plasma: α-tocopherol, beta-carotene and retinol.
- Determining the lipidomic plasma profile gathering lipid species in more classes associated with the risk of cardiovascular disease; P. Detecting inflammatory markers: Tumor necrosis factor (TNF-α), interleukin (IL-6) in plasma.
- Determine the concentration of hepatic enzymes R. Determine the leptin, adiponectin, ghrelin and resistin S. To evaluate the liver ultrasound and carotid ultrasound

Questions about this trial
What is this clinical trial studying?
A study testing ketogenic diet in people with Epilepsy and Cardiovascular Disease, run by University of Sao Paulo at 1 site in Brazil.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 31 Dec 2015. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Brazil. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Nagila Raquel Teixeira Damasceno, Ph D (+55(11) 3061-7865, nagila@usp.br), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Socioeconomic and clinical profile (time frame: average of 3 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02644239, which also lists 13 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 31 Dec 2015.
