Correlation between uric acid and high density lipoprotein cholesterol ratio and diabetic nephropathy in patients with type 2 diabetes mellitus / 中华内分泌外科杂志

ABSTRACT

Objective:To investigate the correlation between serum uric acid/high density lipoprotein cholesterol (URH) and diabetic nephropathy in patients with type 2 diabetes mellitus (T2DM) .Methods:According to urinary albumin creatinine ratio, 171 patients with T2DM were divided into simple T2DM group (group A1), microalbuminuria group (group A2) and macroalbuminuria group (group A3). The general data, HbA1c, biochemical indices were compared, and URH was calculated.Results:The systolic blood pressure, diastolic blood pressure, SUA, TG and URH of A1 group were lower than those of the other two groups [ (129.7±15.78) vs (141.65±16.04) vs (147.31±17.01) mmHg, (78.9±10.71) vs (83.79±10.67) vs (84.61±12.19) mmHg, 291.5 (253.75, 351.25) vs 346 (280, 409) vs 344.5 (274.75, 425.75) μmol/L, 26.12 (19.71,32.96) vs 33.45 (26.55,42.2) vs 33.45 (26.55,42.2) ] ( P<0.05). HDL-C was higher than those of the other two groups [1.19 (1.02,1.29) vs1.02 (0.87,1.21) vs 1.07 (0.93,1.25) mmol/L] ( P<0.05), the course of disease and SCr of group A3 were higher than those of the other two groups [10.5 (7.25, 15) vs 8.5 (4,12) vs 8 (3,11) years; 82.5 (70.57,101.75) vs 66 (52.75,73.75) vs 64 (51, 84) μmol/L ] ( P<0.05), and eGFR was lower than those of the other two groups [91.63 (67.09, 112.21) vs 116.7 (96.6, 142.53) vs 109.85 (85.64, 152.39) ml/min/1.73 m 2] ( P<0.05). There were no significant differences in gender, smoking history, drinking history, age, BMI, TC, LDL-C, BUN, FPG or HbA1c among different groups (P> 0.05). Correlation analysis showed that the course of disease, systolic blood pressure, diastolic blood pressure, TG, SUA, URH were positively correlated with UACR, while HDL-C was negatively correlated with UACR. Logistic regression analysis showed that course of disease was a risk factor for macroproteinuria, while systolic blood pressure and URH were risk factors for microproteinuria and macroproteinuria. ROC curve showed that the AUC value of URH was the highest, and the accuracy rate was 69.3%. Conclusions:URH is closely related to the occurrence of DKD and is a risk factor of DKD. Dynamic monitoring of URH in T2DM patients is helpful for early screening of DKD, which is superior to SUA and HDL-C.
