Prebiotics and the Management of Hyperuricemia

Официальное название

Precision Treatment of Hyperuricemia Based on Different Combinations of Prebiotics

Обзор

Hyperuricemia is a major risk factor for many chronic diesease. Recently, gut mcirobiota has been identified as a novel theraputic target for hyperuricemia. Both annimal studies and pilot human trials have demonstrated that administration of prebiotics help delay the progression of hyperuricemia throuh several mechanisms. This trial aims to examine its protective effects and potential mechanisms in clinical trials.

Подробное описание

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 and hippuric acid.

However, whether administration of prebiotics also has a protective effect in subjects with hyperuricemia remain under-explored. Moreover, whether the original gut microbiota will influence the protective effect of prebiotics remains largely unknown.
