October 1, 2024 updated by: Tina Hsueh-Ting Chiu, Fu Jen Catholic University

Effects of a Healthy Vegan Diet Vs. Low Purine Diet, with or Without Amla Fruits (Emblica Officinalis) on Hyperuricemia and Other Cardiometabolic Risk Factors: a Randomized Two-by-two Factorial Trial

This is an intervention study aiming to test the effectiveness of a vegan diet, My Plate with low purine choices, and amla fruits on uric acid and other cardiometabolic risk factors in individuals with high serum uric acid levels.

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

Ninety-two participants with hyperuricemia will be randomly assigned to one of these 4 diet interventions: (1) vegan, (2) vegan with amla fruits, (3) my plate-low purine, (4) my plate-low purine with amla fruits. During the 3 months intervention phase, participants will attend group lessons and individual nutrition counseling sessions to assist adherence to the diet. At baseline, end of 3 months, and 1 year, participants will be measured on uric acid and other cardiometabolic risk factors, and some nutritional markers. Amla fruits powder, and some foods encouraged in each dietary arm will be provided to enhance adherence during the 3 months intervention phase.

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.
