Insights
Mixing insulin detemir with insulin aspart showed equivalent blood glucose control compared to separate injections in children with type 1 diabetes. This offers a convenient option for pediatric diabetes management.
Area of Science:
- Pediatric Endocrinology
- Diabetes Mellitus Management
- Pharmacology
Background:
- Type 1 diabetes (T1D) requires careful blood glucose management in children.
- Insulin therapy is a cornerstone of T1D treatment.
- Convenience in insulin administration is crucial for adherence in pediatric patients.
Purpose of the Study:
- To compare the efficacy of mixed insulin detemir and aspart versus separate injections in pediatric T1D patients.
- To evaluate blood glucose control parameters between the two administration methods.
Main Methods:
- A crossover study design involving 14 children with T1D.
- Participants received both mixed and separate insulin injections over two 10-day periods.
- Continuous glucose monitoring (CGM) was utilized for 72 hours during each study period.
Main Results:
- No significant differences were observed in the 48-hour area under the glucose curve (AUC) between mixed and separate injections (P = 0.58).
- M-values, indicating glucose stability, were also comparable (P = 0.98).
- Mean amplitude of glucose excursion (MAGE) showed no significant difference (P = 0.42).
Conclusions:
- Administering insulin detemir mixed with insulin aspart is therapeutically equivalent to separate injections for blood glucose control in children with T1D.
- This finding supports the potential for simplified insulin regimens in pediatric diabetes care.
Objective:
We hypothesized that insulin detemir mixed with aspart had equivalent effects on blood glucose as if being given as separate injections in pediatric type 1 diabetes patients.
Research Design And Methods:
Fourteen children with type 1 diabetes were randomly assigned to either Study A (mixed insulins) or Study B (separate insulins) for the first 10 days and crossed over for the last 10 days. Each subject underwent continuous glucose monitoring on the last 72 h of each study.
Results:
The 48-h area under the curve (mmol/hour/l), M-value, and mean amplitude of glucose excursion (mmol/l) for Study A versus Study B were 457 +/- 70 versus 469 +/- 112 (P = 0.58), 39.67 +/- 15.37 versus 39.75 +/- 9.69 (P = 0.98), and 6.35 +/- 1.92 versus 5.98 +/- 0.92 (P = 0.42), respectively.
Conclusions:
Insulin detemir mixed with aspart had equivalent effects on blood glucose versus giving them as separate injections in children with type 1 diabetes.
