Mixing insulin aspart with detemir does not affect glucose excursion in children with type 1 diabetes

Abstract

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. © 2010 by the American Diabetes Association.
