BACKGROUND: Epidemiological studies suggest that elevated serum uric acid (SUA) is associated with heightened incident kidney disease in both the general population and the type 2 diabetes (T2D) cases, although the results were not entirely consistent. METHODS: ) among 3123 T2D in the Dongfeng-Tongji cohort and further examined this association with a meta-analysis. Generalize linear model was used to assess the associations of SUA with eGFR decline in the cohort. In the meta-analysis, we used both fix-effects and random-effects models to calculate the overall effect estimate. RESULTS: During 5-year follow-up, 303 (9.7%) patients developed eGFR decline. After multiple adjustments, the relative risk (RR) (95% CI) of eGFR decline was 1.55 (1.07, 2.26) when comparing the highest with the lowest sex-specific uric acid quartile. A 100 μmol/L increment of SUA level was significantly associated with 21% increased risk of eGFR decline. The SUA-eGFR decline association was more evident in men, but not in women. In meta-analysis, the pooled RR (95% CI) was 2.33 (1.66, 3.25) for developing eGFR decline when comparing the highest with the lowest levels of uric acid. A 100 μmol/L increment of SUA level was significantly associated with a 33% increased risk of eGFR decline. CONCLUSIONS: Our results indicate an independent and significant positive association between higher SUA and increased risk of developing eGFR decline among T2D cases.
