Objective:
The primary objective of this study was to assess the impact of fecal microbiota transplantation (FMT) on serum biochemical parameters, renal injury, and gut microbiota in hyperuricemia (HUA) mice.
Methods:
Six-week-old male C57BL/6 J mice were given a high-purine diet and potassium oxonate injections to induce HUA, followed by a two-week FMT treatment. Regular body weight checks, serum biochemical analyses, and fecal sampling for 16S rRNA gene sequencing were conducted to evaluate the treatment's impact on gut microbiota.
Results:
The model group showed significant increases in uric acid (UA), creatinine (Cr), blood urea nitrogen (BUN) levels, and increased xanthine oxidase (XOD) activity compared to controls (p < 0.05). FMT treatment effectively reduced these levels and XOD activity (p < 0.05). At the genus level, specific taxa like Muribaculaceae and Prevotellaceae_UCG-001 were less abundant, while Blautia and Ruminiclostridium_9 were more abundant in the model group. Following FMT, gut microbiota composition returned to near-normal levels, with significant differences from the model group (p < 0.05).
Conclusion:
This study demonstrates that FMT holds therapeutic potential for HUA mice by reducing UA levels, alleviating renal damage, and restoring gut microbiota balance.
