Sun Yat-sen University120 enrolled

Overview

Hyperuricemia is a major risk factor for many chronic diseases. Recently, dysbiosis of gut microbiota has been reported to play an important role in the pathogenesis of Hyperuricemia. Animal studies have demonstrated that administration of prebiotics help delay the progression of Hyperuricemia through several mechanisms. This trial aims to examine its protective effect in humans.

Hyperuricemia is a major risk factor for many chronic diseases. Recently, dysbiosis of gut microbiota has been reported to play an important role in the pathogenesis of hyperuricemia. Animal studies have demonstrated that administration of prebiotics help delay the progression of hyperuricemia through several mechanisms such as reduction in endotoxemia, and enhanced production of short-chain fatty acids. However, whether administration of prebiotics also has a protective effect in subjects with Hyperuricemia remain unknown.
