Artemisia and Green Tea Extracts for Gastric Mucosal Health

Pusan National University Yangsan Hospital100 enrolled

Overview

This clinical trial aims to determine whether Artemisia and green tea extracts promote gastric mucosal health in adults with functional dyspepsia and to assess its safety. The main questions are: * Does Artemisia and green tea extracts promote gastric mucosal health in participants? * What side effects occur when participants take Artemisia and green tea extracts?

Researchers will compare Artemisia and green tea extracts to placebo to evaluate their effectiveness in promoting gastric mucosal health. Participants will: * Take Artemisia and green tea extracts or a placebo daily for 8 weeks. * Visit the clinic every 4 weeks for checkups and tests.

Outcomes

Primary Outcomes

The Korean version of the Gastrointestinal Symptom Rating Scale: Total score

Measured at baseline and 8 weeks. This is a 4-point Likert scale for each of the 15 items, with scores ranging from 0 to 3. A score of 0 indicates no symptoms, and 3 represents very severe symptoms. The higher the overall score, the more severe the gastrointestinal symptoms. The minimum value was 0, and the maximum value was 45, and higher scores mean a worse outcome.

Time frame: From enrollment to the end of treatment at 8 weeks

Secondary Outcomes

The Korean version of the Gastrointestinal Symptom Rating Scale: Subtotal scores of upper abdomen

Measured at baseline and 8 weeks. This is a 4-point Likert scale for each of the 8 items, with scores ranging from 0 to 3. A score of 0 indicates no symptoms, and 3 represents very severe symptoms. The higher the overall score, the more severe the gastrointestinal symptoms. The minimum value was 0, and the maximum value was 21, and higher scores mean a worse outcome.

Time frame: From enrollment to the end of treatment at 8 weeks

Visual Analogue Scale for evaluating gastric mucosal improvement

Measured at baseline and 8 weeks. The minimum value was 0 and the maximum value was 100, and higher scores mean a worse outcome.

Time frame: From enrollment to the end of treatment at 8 weeks

Gastrointestinal symptom score

Measured at baseline and 8 weeks. The minimum value was 0 and the maximum value was 40, and higher scores mean a worse outcome. For each gastrointestinal symptom, the minimum value was 0, and the maximum value was 4, and higher scores mean a worse outcome.

Time frame: From enrollment to the end of treatment at 8 weeks

Patient's global assessment score

Measured at baseline and 8 weeks. The 5-point Likert scale for the Patient's Global Assessment Score is a self-reported tool where patients rate their disease activity. It uses an order scale, with 5 indicating "Very Good" and 1 indicating "Poor." The patient evaluates their condition based on this scale: Very Good-Good-Fair-Unchanged-Poor.
