DF(Oat Bran) Intervention on Inflammation, Intestinal Flora, Disease Activity and Quality of Life in Patients With RA

August 29, 2024 updated by: Shenzhen People's Hospital

Effects of Dietary Fiber (Oat Bran) Intervention on Inflammation, Intestinal Flora, Disease Activity and Quality of Life in Patients With Rheumatoid Arthritis

The goal of this clinical trial is to test in Rheumatoid arthritis. The main question it aims to answer are:

  • To verify the effect of dietary fiber supplementation on reducing the level of inflammation;
  • To verify the effect of dietary fiber supplementation on improving disease activity and quality of life in patients with rheumatoid arthritis .To verify the effect of dietary fiber supplementation on regulating the production of anti-inflammatory short-chain fatty acid in the gut of patients with rheumatoid arthritis.

The experimental group was supplemented with dietary fiber for 12 weeks, and the control group was fed with the Mediterranean diet. Before and after the intervention, 1 tube of 3ml blood and 1 soybean-sized stool were taken and a questionnaire was made

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

Rheumatic arthritis (RA) is caused by chronic inflammation and joint injury caused by imbalance of pro-and anti-inflammatory mediators in the joints. Studies have shown that dietary fiber (DF) can be fermented by gut bacteria into anti-inflammatory short-chain fatty acid that may reduce joint inflammation, relieve symptoms and improve quality of life. The subjects were Randomized controlled trial to supplement DF12W individually, the intervention group to supplement DF12W, and the control group to supplement DF12W with routine diet, the differences of disease activity (DAS28 score) , inflammatory markers (TNF-a, IL-6, Mir-146a, Treg, ESR, CRP, etc.) and quality of life (SF-36) between the two groups were compared. The changes of intestinal flora were examined to verify the hypothesis. This study laid a good scientific foundation for dietary recommendation of RA patients.

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

  • Adult

Experimental: Experimental group
12 week Mediterranean diet+dietary fiber intervention
Dietary supplement: Oat bran (dietary fiber)
Dietary fiber, known as the "seventh type of nutrients," refers to carbohydrate polymers that have health benefits for the human body, mainly derived from plant cell walls such as grains, fruits, and vegetables.Mediterranean cuisine is a dietary pattern

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description

Disease activity score
Time Frame: 12 weeks
Questionnaire evaluation,Higher scores mean worse results

Adjustment of anti rheumatic drugs
Time Frame: Week 12
The increment and decrement are unchanged.Incremental means going from not taking a synthetic anti-rheumatic drug to taking a synthetic anti-rheumatic drug, or increasing the dose of the original drug, or increasing the type of drug, or from the original traditional synthesis of disease-improving anti-rheumatic drugs adjusted for the biological synthesis of disease-improving anti-rheumatic drugs. A reduction in the dose of a synthetic anti-rheumatic drug is defined as a reduction in the dose of a synthetic anti-rheumatic drug from taking it to discontinuing it, or a reduction in the dose of the original drug, or from the original bio-synthesis to improve the condition of anti-rheumatic drugs adjusted to traditional synthesis to improve the condition of anti-rheumatic drugs
