Abstract

Aims: Several studies have shown that twice-daily injection of premixed insulin analog (MIX) therapy achieves glycemic control equivalent to that with basal-bolus (BB) therapy. However, glycemic fluctuations that lead to oxidative stress may be associated with the risk of diabetic complications. Therefore, in this study, we compared oxidative stress markers between MIX therapy and BB therapy. Methods: In this cross-sectional study, we recruited a total of 37 patients (17 patients in the BB group and 20 patients in the MIX group) and compared urinary 8-isoprostane and urinary 8-hydroxydeoxyguanosine (8-OHdG) levels. Results: There were no significant differences in urinary 8-isoprostane (BB vs MIX: 199±92 pg/mg Cr vs 266±107 pg/mg Cr) or urinary 8-OHdG (4.7±1.6 ng/mg Cr vs 5.4±1.9 ng/mg Cr, respectively). Conclusion: These results suggest that MIX is equivalent to BB in terms of glycemic fluctuations and oxidative stress.
