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.

Project description:BackgroundChronically elevated blood glucose levels are associated with significant morbidity and mortality. Many diabetes patients will eventually require insulin treatment to maintain good glycaemic control. There are still uncertainties about the optimal insulin treatment regimens for type 2 diabetes, but the long-acting insulin analogues seem beneficial. Several reviews have compared either insulin detemir or insulin glargine to NPH insulin, but research directly comparing both insulin analogues is limited.ObjectivesTo assess the effects of insulin detemir and insulin glargine compared with each other in the treatment of type 2 diabetes mellitus.Search strategyWe searched MEDLINE, EMBASE, The Cochrane Library, online registries of ongoing trials and abstract books. Date of last search was January 2011.Selection criteriaAll randomised controlled trials comparing insulin detemir with insulin glargine with a duration of 12 weeks or longer were included.Data collection and analysisTwo authors independently selected the studies and extracted the data. Pooling of studies by means of random-effects meta-analysis was performed.Main resultsThis review examined four trials lasting 24 to 52 weeks involving 2250 people randomised to either insulin detemir or glargine. Overall, risk of bias of the evaluated studies was high. Insulin glargine was dosed once-daily in the evening. Insulin detemir was initiated once-daily in the evening with the option of an additional dose in the morning in three studies and initiated twice-daily in one study. Of randomised patients 13.6% to 57.2% were injecting insulin detemir twice-daily at the end of trial.Glycaemic control, measured by glycosylated haemoglobin A1c (HbA1c) and HbA1c equal to or less than 7% with or without hypoglycaemia, did not differ statistically significantly between treatment groups.The results showed no significant differences in overall, nocturnal and severe hypoglycaemia between treatment groups.Insulin detemir was associated with less weight gain. Treatment with insulin glargine resulted in a lower daily basal insulin dose and a lower number of injection site reactions.There was no significant difference in the variability of FPG or glucose values in 24-hour profiles between treatment groups. It was not possible to draw conclusions on quality of life, costs or mortality. Only one trial reported results on health-related quality of life and showed no significant differences between treatment groups.Authors' conclusionsOur analyses suggest that there is no clinically relevant difference in efficacy or safety between insulin detemir and insulin glargine for targeting hyperglycaemia. However, to achieve the same glycaemic control insulin detemir was often injected twice-daily in a higher dose but with less weight gain, while insulin glargine was injected once-daily, with somewhat fewer injection site reactions.

Project description:AimsTo investigate the pharmacokinetic/pharmacodynamic properties of fast-acting insulin aspart (faster aspart) versus insulin aspart (IAsp) in people with type 2 diabetes (T2D).Materials and methodsIn a randomized, double-blind, crossover design, 61 people with T2D usually treated with insulin ± oral antidiabetic drug(s) received single-dose faster aspart and IAsp (0.3 U/kg) on separate visits. Blood samples for pharmacokinetic assessment were collected frequently until 12 hours post-dose. Glucose-lowering effect was determined in a euglycaemic clamp lasting up to 12 hours post-dose (target 5.0 mmol/L).ResultsThe serum IAsp pharmacokinetic profile and glucose-lowering effect profile were shifted to the left for faster aspart versus IAsp. Least squares mean (± SE) onset of appearance was 3.3 ± 0.3 minutes for faster aspart, which was 1.2 minutes earlier than for IAsp (95% confidence interval [CI] -1.8;-0.5; P = .001). Onset of action for faster aspart was 8.9 minutes earlier (95% CI -12.1;-5.7; P < .001) than for IAsp. During the first 30 minutes after dosing, 89% larger IAsp exposure (ratio faster aspart/IAsp 1.89 [95% CI 1.56;2.28]; P < .001) and 147% greater glucose-lowering effect (2.47 [95% CI 1.58;6.22]; P < .001) were observed for faster aspart compared with IAsp. Offset of exposure (time to 50% of maximum IAsp concentration in the late part of the pharmacokinetic profile) occurred earlier for faster aspart (difference faster aspart - IAsp -36.4 minutes [95% CI -55.3;-17.6]; P < .001). The treatment difference of faster aspart - IAsp in offset of glucose-lowering effect (time to 50% of maximum glucose infusion rate in the late part of the glucose infusion rate profile) was -14.4 minutes (95% CI -34.4;5.5; P = .152).ConclusionsIn people with T2D, faster aspart was associated with earlier onset and greater initial exposure and glucose-lowering effect compared with IAsp, as previously shown in people with type 1 diabetes.
