Abstract
PURPOSE: Urinary kidney injury molecule-1 and monocyte chemoattractant protein-1 are significance factors in the diagnosis and intervention of diabetic kidney diseases. This study determined levels of these proteins in diabetic patients with varying degrees of kidney disease and assessed their relationship with risk factors associated with diabetic kidney diseases. METHODS: A total of 185 patients with type 2 diabetes were divided into three groups [low risk (n = 47), moderate risk (n = 63), and high risk (n = 75)] based on the severity of diabetic kidney disease according to kidney disease: improving global outcomes guidelines. Both urinary kidney injury molecule-1 and monocyte chemoattractant protein-1 levels were measured by enzyme-linked immunosorbent assay. Student`s t test, analysis of variance, and Spearman's correlation were used for statistical analysis. RESULTS: The kidney injury molecule-1-to-creatinine ratio (P = 0.035) and monocyte chemoattractant protein-1-to-creatinine ratio (P < 0.001) increased significantly with the increase in kidney disease severity and varied according to different albuminuria statuses and estimated glomerular-filtration rates. The monocyte chemoattractant protein-1-to-creatinine ratio showed a significant correlation with hemoglobin A1c (P = 0.002) and inflammatory marker levels (interleukin-6, P = 0.005; tumor necrosis factor-α, P < 0.001). CONCLUSION: Urinary levels of both kidney injury molecule-1 and monocyte chemoattractant protein-1 represent distinguishing markers for the evaluation of diabetic kidney disease progression according to the associated degrees of albuminuria or/and the estimated glomerular-filtration rate. In addition, correlations between urinary monocyte chemoattractant protein-1 and glycemic and inflammatory marker levels revealed the role of hyperglycemia and chronic inflammation in the pathogenesis of diabetic kidney disease.
