Characteristics of the gut microbiome of asymptomatic hyperuricemia

Asymptomatic hyperuricemia(AH) is characterized by elevated blood uric acid levels without symptoms,posing risks like gout, kidney stones, and cardiovascular diseases. This study aims to investigate the role of the gut microbiota in uric acid metabolism in AH.

Clinical data from 30 AH patients and 30 healthy controls were collected. Fecal microbiota genomic DNA was extracted, PCR amplified, library constructed, and sequenced. Bioinformatics and statistical analyses were conducted to study the gut microbiota of the two groups.

The AH group exhibited significantly elevated levels of body mass index (BMI), Triglycerides (TG), Total Cholesterol (TC), as along with a history of smoking, hypertension, and fatty liver disease compared to the healthy group (P < 0.05). The overall richness and ecological diversity of gut microbiota in the AH group decreased, with differences in the distribution at the phylum and genus levels compared to the healthy group. Uric acid demonstrated significant correlations with various gut microbiota (e.g., Granulicatella), suggesting their potential as biomarkers for AH. Despite limitations such as a small sample size and lack of long-term follow-up, our findings provide new insights for the early diagnosis and personalized treatment of AH. Looking ahead, these discoveries may advance the clinical management of AH and the exploration of associated biomarkers.
