| description | <i>Background and Objectives</i>: The present study aims to investigate the association between gut microbiota’s oxalate-degrading activity (ODA) and the risk of developing cardiovascular disease (CVD) over a three-year follow-up period in a cohort of patients undergoing kidney replacement therapy (KRT). Additionally, various factors were examined to gain insight into the potential mechanisms underlying the ODA–CVD link. <i>Materials and Methods</i>: A cohort of 32 KRT patients and 18 healthy volunteers was enrolled in this prospective observational pilot study. Total fecal ODA, routine clinical data, plasma oxalic acid (POx), serum indoxyl sulfate, lipid profile, oxidative stress, and proinflammatory markers were measured, and the patients were followed up for three years to assess CVD events. <i>Results</i>: The results revealed that patients with kidney failure exhibited significantly lower total fecal ODA levels compared to the healthy control group (<i>p</i> = 0.017), with a higher proportion showing negative ODA status (≤−1% per 0.01 g) (<i>p</i> = 0.01). Negative total fecal ODA status was associated with a significantly higher risk of CVD events during the three-year follow-up period (HR = 4.1, 95% CI 1.4–16.3, <i>p</i> = 0.003), even after adjusting for potential confounders. Negative total fecal ODA status was significantly associated with elevated POx and indoxyl sulfate levels and linked to dyslipidemia, increased oxidative stress, and inflammation, which are critical contributors to CVD. <i>Conclusions</i>: The findings contribute novel insights into the relationship between gut microbiota’s ODA and cardiovascular health in patients undergoing KRT, emphasizing the need for further research to elucidate underlying mechanisms and explore potential therapeutic implications of targeting gut microbiota’s ODA in this vulnerable population. |
