Hyperuricemia as Early Indication of CKD Progressing in Prediabetic

Chronic kidney disease (CKD) is a major global health problem, and hyperuricemia has emerged as both a consequence and a potential driver of its progression. Elevated uric acid contributes to renal impairment through oxidative stress, endothelial dysfunction, inflammasome activation, and crystal deposition. Epidemiological studies show that hyperuricemia often precedes CKD and serves as an independent predictor, with prevalence reaching up to 38% among CKD patients. Prediabetes, another growing health concern, is associated with higher serum uric acid levels and increased risk of developing both diabetes and CKD. Factors such as obesity, fatty liver, and dyslipidemia mediate this link. Clinically, higher uric acid levels are correlated with faster eGFR decline and higher risk of ESRD, with the uric acid/HDL ratio proposed as a novel risk marker. Although debate persists about whether hyperuricemia directly causes CKD, emerging genetic and epidemiological evidence supports its independent role. Given the rising prevalence of prediabetes and hyperuricemia, identifying hyperuricemia as a modifiable early predictor of CKD progression in prediabetic patients could help improve prevention, risk stratification, and management
