Objectives: To compare the efficacy and safety of insulin glulisine over regular insulin in patients with type 2 diabetes and severe renal insufficiency.
Subjects: Our study included 18 patients with type 2 diabetes and a mean (range) estimated glomerular filtration rate of 13.2 mL/minute/1.73 m(2) (5.8-27.6), which corresponds to stage 4-5 chronic kidney disease.
Design: After titration of doses, regular insulin was administered thrice daily on Day 1, along with continuous glucose monitoring for 24 h starting at 7 am. Exactly equal doses of insulin glulisine were administered on Day 2. Area under the curve (AUC) for blood glucose level variation after breakfast (AUC-B 0-4), lunch (AUC-L 0-6), and dinner (AUC-D 0-6) were evaluated.
Results: AUC-B 0-4 and AUC-D 0-6 were significantly lower with insulin glulisine than with regular insulin (AUC-B 0-4: 3.3 ± 4.7 vs. 6.2 ± 5.4 × 10(2) mmol/L·minute, respectively, P = .028; AUC-D 0-6: 1.8 ± 7.3 vs. 6.5 ± 6.2 × 10(2) mmol/L·minute, respectively, P = .023). In contrast, AUC-L 0-6 was higher with insulin glulisine than with regular insulin (AUC-L 0-6: 7.6 ± 6.4 vs. 4.2 ± 8.7 × 10(2) mmol/L·minute, respectively, P = .099), suggesting a prolonged hypoglycemic action of regular insulin after lunch.
Conclusions: Insulin glulisine effectively suppressed postprandial hyperglycemia, whereas regular insulin caused a prolonged hypoglycemic action. These findings support the effectiveness and safety of insulin glulisine in patients with type 2 diabetes and severe renal insufficiency.
