Abstract

Background

The oxidative stress resulting from increased production of ROS plays a crucial role in the development of diabetic complications. We aim to explore the relationships between oxidative stress, diabetic nephropathy (DN) and short-term insulin pump intensive therapy (insulin therapy).

Methods

Levels of 8-hydroxy-deoxyguanosine (8-OHdG), 3-nitrotyrosine (3-NT), glutathione (GSH), superoxide dismutase (SOD) and Interleukin-6 (IL-6) were estimated before and after 2 weeks of insulin therapy in normal group (NC) and type 2 diabetic (DM) with normal albuminuria (NA), microalbuminuria (MA) and clinical albuminuria (CA).

Results

In DM group, levels of 8-OHdG and 3-NT were higher than those in NC group (P < 0.05); GSH and SOD were lower (P < 0.05). And their levels changed with urine albumin–creatinine ratio (P < 0.05). After insulin therapy, these derangements were significantly ameliorated and the changes in NA and MA groups were more significant than CA group (P < 0.05). Correlation analysis showed glycated hemoglobin, the course of disease, the HOME-IR and fasting plasma glucose were positively correlated with 8-OHdG and 3-NT, but negatively correlated with GSH and SOD.

Conclusions

The oxidative stress gradually increased with the magnitude of DN, and insulin pump intensive therapy can significantly ameliorate the derangements in the early stage of DN.
