Using galactooligosaccharides to manage high uric acid levels

The Effectiveness of Galactooligosaccharide on the Treatment of Hyperuricemia

Not applicable Interventional Sun Yat-sen University · NCT06630377

This study tests whether a type of fiber called galactooligosaccharides can help people with high uric acid levels feel better by improving gut health.

What this trial studies

This clinical trial investigates the effects of galactooligosaccharides (GOS) on hyperuricemia, a condition linked to various chronic diseases. The study aims to explore how GOS may influence gut microbiota and its potential protective mechanisms against elevated uric acid levels. Participants will receive either GOS or a placebo, and their responses will be monitored to assess the efficacy of this intervention. The trial seeks to fill gaps in understanding the relationship between gut health and hyperuricemia.

Who should consider this trial

Good fit: Ideal candidates are local residents aged 18-80 with stable weight and elevated fasting uric acid levels who are not currently on uric acid-lowering medications.

Not a fit: Patients with acute illnesses, chronic inflammatory diseases, or those on interfering diets or medications will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a novel dietary intervention for managing hyperuricemia and reducing the risk of associated chronic diseases.

How similar studies have performed: While animal studies and pilot human trials have shown promise with prebiotics for hyperuricemia, the specific use of galactooligosaccharides in this context remains largely unexplored.
