About this study

Official title: Effects of Nutritional Supplementation With Amino Acids on Liver Lipid Content, Whole-body Protein Turnover, and Body Composition in Obese Pre-pubertal Children

The purpose of this study is to assess the effect of an eight-week dietary supplementation with essential amino acids plus arginine on liver and plasma lipid content, whole-body fat oxidation, whole-body insulin sensitivity, whole body protein metabolism, and body composition in obese pre-pubertal children.

Read the detailed description

Up to thirty-two obese pre-pubertal children will be recruited for this study. Up to sixteen will be boys and up to sixteen will be girls. The study will be a double-blinded, placebo-controlled trial using a randomized, but counter-balanced design. This will ensure equal numbers in the two groups that the children are randomized to, for each sex. The control group will receive placebo and the intervention group will receive essential amino acids plus arginine. The supplements (essential amino acids plus arginine, and placebo) will be given in the form of a drink twice a day for a total of 8 weeks. Both the participants and the investigators will be blinded to group assignment.

The primary endpoints of this study are to assess the effect of essential amino acids (EAA) plus arginine supplementation on lipid and protein metabolism. For this, liver lipid content, hepatic apoptosis, plasma lipids, apolipoprotein B-100 (apo B-100) levels, hepatic fatty oxidation, whole body insulin sensitivity, body composition and whole body protein turnover. will be compared between the intervention and placebo groups.

Study groups in NCT02337894
Study groupRoleWhat they receive
Essential amino acids plus arginineExperimentalChildren randomized to the intervention group will receive a supplement containing essential amino acids plus arginine in the form of a drink which they will have to take for 8 weeks. Measurement of liver lipid content, hepatic apoptosis, plasma lipids, apolipoprotein B-100 levels, hepatic fatty oxidation, whole body insulin sensitivity, body composition and whole body protein turnover will be compared with the the placebo group, and before and after the intervention.
Receives: Dietary Supplement: Essential amino acids plus arginine
Control drinkPlacebo comparatorThe control drinks will be indistinguishable from the intervention drinks in taste and volume, but will contain placebo rather than essential amino acids plus arginine.
Receives: Dietary Supplement: Placebo

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Serum levels of markers of lipid metabolism before and after 8 weeks of supplementation with essential amino acids plus arginine vs placebo.

    Change in serum levels of triglycerides, cholesterol, very low density lipoprotein (VLDL), low density lipoprotein (LDL), beta-hydroxybutyrate, Apo-lipoprotein B and plasma cytokeratin 18 will be assessed after 8 weeks of essential amino acids plus arginine vs placebo.

    Measured: Baseline and 8 weeks

  2. Liver lipid content before and after 8 weeks of supplementation with essential amino acids plus arginine vs placebo.

    Nuclear Magnetic Resonance Spectroscopy will be used to assess changes in liver lipid content following an 8-week supplementation period with essential amino acids plus arginine vs. placebo.

    Measured: Baseline and 8 weeks

  3. Whole body protein turnover before and after 8 weeks of supplementation with essential amino acids plus arginine vs. placebo.

    Change in whole body protein metabolism (synthesis and breakdown) following 8 weeks of essential amino acids plus arginine vs placebo. This outcome will be assessed using a stable isotope of an amino acid (15N-alanine).

    Measured: Baseline and 8 weeks

  4. Body composition before and after 8 weeks of supplementation with essential amino acids plus arginine vs. placebo.

    Changes in body composition (fat free mass and fat mass) will be assessed using Dual-Energy X-ray Absorptiometry. Measurements will be carried out at baseline and following 8 weeks of supplementation with essential amino acids plus arginine vs. placebo.

    Measured: Baseline and 8 weeks

Secondary outcomes (1)
  1. HOMA-IR index before and after 8 weeks of supplementation with essential amino acids plus arginine vs placebo.

    Fasting glucose and insulin levels will be used to assess changes in the HOMA-IR index after 8 weeks of supplementation with essential amino acids plus arginine vs. placebo.

    Measured: Baseline and 8 weeks

Questions about this trial

What is this clinical trial studying?

A study testing Essential amino acids plus arginine in people with Liver Steatosis and Insulin Resistance, run by Arkansas Children's Hospital Research Institute.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 3 exclusion criteria. 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: withdrawn, as of the sponsor's last update on 2 Oct 2025. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. 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?

The study was withdrawn before enrolling participants, so there are no results.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Serum levels of markers of lipid metabolism before and after 8 weeks of supplementation with essential amino acids plus arginine vs placebo. (time frame: Baseline and 8 weeks). The study lists 4 primary outcomes in all. 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 NCT02337894, which also lists 3 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 2 Oct 2025.
