Serum and Urinary SOD3 in Patients with Type 2 Diabetes: Comparison with Early Chronic Kidney Disease and Association with Development of Diabetic Nephropathy.

Serum and Urinary SOD3 in Patients with Type 2 Diabetes: Comparison with Early Chronic Kidney Disease and Association with Development of Diabetic Nephropathy. Am J Physiol Renal Physiol. 2018 Oct 10;: Authors: Kuo CW, Chen HL, Tu MY, Chen CM Abstract Extracellular superoxide dismutase (SOD3), one member of the antioxidant defense system and a superoxide scavenger, has been noted to be downregulated in the kidneys of diabetic mice and is characterized by a heparin-binding domain that can anchor the protein to the endothelium and extracellular matrix. The association of the serum and urinary SOD3 levels with diabetic nephropathy in different stages has never been evaluated. It remains unclear how urinary SOD3 changes in different renal diseases. We recruited 98 Taiwanese patients with type 2 diabetes and 10 patients with early chronic kidney disease (CKD) into this study. Biochemical analyses were performed, including evaluation of the serum SOD3, urinary SOD3, urinary albumin, urinary vascular endothelial growth factor (VEGF) and urinary angiotensinogen (ANG). The Kruskal-Wallis rank sum test was used to compare various parameters among the three groups of patients, early CKD, diabetes alone and diabetes with CKD. Results showed that lower serum and urinary SOD3 levels were observed in the group of patients with diabetes alone. Higher serum and urinary SOD3 levels were observed in the group of diabetes with CKD patients, which has hi...
