Abstract
Abstract
Gut dysbiosis is suggested to play a critical role in the pathogenesis of gout. The aim of our study was to identify the characteristic dysbiosis of the gut microbiota in gout patients and the impact of a commonly used uric acid-lowering treatment, febuxostat on gut microbiota in gout. 16S ribosomal RNA sequencing and metagenomic shotgun sequencing was performed on fecal DNA isolated from 38 untreated gout patients, 38 gout patients treated with febuxostat, and 26 healthy controls. A restriction of gut microbiota biodiversity was detected in the untreated gout patients, and the alteration was partly restored by febuxostat. Biochemical metabolic indexes involved in liver and kidney metabolism were significantly associated with the gut microbiota composition in gout patients. Functional analysis revealed that the gut microbiome of gout patients had an enriched function on carbohydrate metabolism but a lower potential for purine metabolism, which was comparatively enhanced in the febuxostat treated gout patients. A classification microbial model obtained a high mean area under the curve up to 0.973. Therefore, gut dysbiosis characterizings gout could potentially serve as a noninvasive diagnostic tool for gout and may be a promising target of future preventive interventions.Keywords: Gout,
