Comparison Between Biomarkers of Kidney Injury, Inflammation, and Oxidative Stress in Patients with Diabetic Nephropathy and Type 2 Diabetes Mellitus
Abstract
Introduction. This study was conducted to compare parameters of kidney injury, oxidative stress and inflammation in people with diabetic nephropathy (DN) and type 2 diabetes mellitus (T2DM). Methods. In a cross-sectional study, 57 cases with DN and 57 cases with T2DM were included in the study. Fasting blood samples were obtained to determine parameters of kidney injury, oxidative stress and inflammation. Results. The current study showed that patients with DN had higher tumor necrosis factor-α (TNF-α) (167.0 ± 40.1 vs. 151.4 ± 37.4 ng/L, P < .05) and matrix metalloproteinase-2 (MMP-2) concentrations (1625.2 ± 631.0 vs. 1391.5 ± 465.4 ng/mL, P < .05) compared with T2DM cases. Moreover, we observed a non-significant increase in MMP-9 levels among patients with DN compared with individuals with T2DM (4864.4 ± 1934.3 vs. 4239.2 ± 1853.9 ng/L, P > .05). Furthermore, advanced glycation end products (AGEs) levels in patients with DN were higher than that of patients with T2DM (8511.7 ± 1799.9 vs. 7660.7 ± 1711.9 AU, P < .05), but the difference in malondialdehyde value was not significant. Finally, we found that total protein levels in cases with DN were enhanced compared with individuals with T2DM (7.1 ± 0.5 vs. 6.9 ± 0.6 mg/dL, P < .05); however, other markers of kidney injury did not change. Conclusions. In conclusion, the results of present study revealed that few markers of inflammation and oxidative stress including TNF-α, MMP-2, AGEs levels and total protein levels in patients with DN were significantly higher than that of patients with T2DN. Further studies are necessary to confirm these findings.Downloads
