Abstract:
Objective:To assess the correlation between hyperuricaemia and normoalbuminuric diabetic kidney disease(NADKD) in elderly type 2 diabetic patients.Methods:This retrospective case-control study enrolled 910 patients with type 2 diabetes mellitus who were hospitalized in the Geriatric Department of Nanjing Drum Tower Hospital from 2015 to 2020. The patients were divided into NADKD group [urinary albumin/creatinine(UACR)<30 mg/g and estimated glomerular filtration rate(eGFR) <60 mL·min -1·(1.73 m 2) -1, n=169)], albuminuria DKD group [UACR ≥30 mg/g and eGFR <60 mL·min -1·(1.73 m 2) -1, n=234], and control group [UACR <30 mg/g and eGFR≥60 mL·min -1·(1.73 m 2) -1, n=507]. Medical history, physical examination, and laboratory tests were collected. Results:The proportion of women in the NADKD group was significantly higher than that in the albuminuric DKD group(50.89% vs 40.60%, P<0.05). Duration of diabetes, HbA 1C, fasting plasma glucose(FPG), the prevalences of hypertension and hyperuricaemia, blood urea nitrogen, blood creatinine, and blood uric acid were significantly lower in the NADKD group than those in the albuminuric DKD group(all P<0.05). Blood urea nitrogen, serum creatinine, triglycerides, serum uric acid and the prevalence of hyperuricemia were significantly higher in the NADKD group compared the control group(all P<0.001) while the proportion of hypertension, systolic blood pressure, LDL-C, HbA 1C, and FPG were lower(all P<0.05). Multivariate linear regression analysis showed that eGFR was negatively associated with urea nitrogen and serum uric acid while positively associated with HbA 1C in normoalbuminuric elderly type 2 diabetic patients(all P<0.001). Logistic regression analysis revealed that hyperuricaemia was a risk factor for NADKD in elderly type 2 diabetic patients after adjusting for BMI, blood pressure, lipids, and glucose( OR=1.963, 95% CI 1.157-3.332, P=0.012). Conclusion:Hyperuricaemia is significantly associated with NADKD in elderly patients with type 2 diabetes.
