In patients with long-term T1D, meal-related insulin dosing based on carbohydrate plus fat/protein counting reduces the postprandial glucose levels (ClinicalTrials.gov NCT01400659).

Aims. This study assesses the impact of using an AP-system at home on fear of hypoglycaemia. In addition, satisfaction and acceptance of the new technology are evaluated. Methods. In a multicentre, multinational study of 75 patients using the MD-Logic AP during four consecutive nights in home setting 59 of them (aged 10–54 years, 54% male, HbA1c 7.89 ± 0.69% [62.72 ± 7.51 mmol/mol], diabetes duration 11.6 ± 8.4 yrs) answered standardized questionnaires (HFS, adapted TAM, and AP satisfaction) before and after using the AP. Results. After experiencing the AP in home setting worries of hypoglycaemia were significantly reduced (before 1.04 ± 0.53 versus after 0.90 ± 0.63; P = 0.017). Perceived ease of use as a measure of acceptance with the AP significantly increased after personal experience (before 4.64 ± 0.94 versus after 5.06 ± 1.09; P = 0.002). The overall satisfaction mean score after using the AP was 3.02 ± 0.54 (range 0–4), demonstrating a high level of satisfaction with this technology. Conclusions. The four-night home-based experience of using MD Logic AP was associated with reduced worries of hypoglycaemia, high level of satisfaction, and increased perceived ease of use of the new technology in children, adolescents, and adults.

Insulin degludec/insulin aspart (IDegAsp) is a soluble coformulation of long-acting insulin degludec and short-acting insulin aspart. This open-label, Phase 1 study aimed to determine the pharmacodynamic and pharmacokinetic properties of IDegAsp in children (6-11 yr), adolescents (12-17 yr), and adults (18-65 yr) with type 1 diabetes mellitus (T1DM). Thirty-eight subjects received single subcutaneous IDegAsp dosing (0.5 U/kg) immediately before a standardized liquid meal (17.3 g carbohydrates/100 mL; adjusted for body weight) followed by plasma glucose (PG) and pharmacokinetic blood sampling for 36 and 57 h, respectively. There were no apparent differences between age groups in PG lowering effect (AUC ), maximum PG excursion (ΔPG ), or maximum PG concentration (PG ) after the standardized meal. Estimated ratios (ERs) for total exposure (AUC ) and maximum concentration (C ) of IAsp in IDegAsp were children/adults, 1.69 (95% confidence interval, CI: 1.02; 2.80) and 1.66 (95% CI: 1.10; 2.51); adolescents/adults, 1.14 (95% CI: 0.76; 1.69) and 1.16 (95% CI: 0.84; 1.61). ERs for total exposure (AUC ) and maximum concentration (C ) of IDeg in IDegAsp were children/adults, 1.42 (95% CI: 0.94; 2.16) and 1.38 (95% CI: 1.09; 1.76); adolescents/adults, 1.23 (95% CI: 0.96; 1.58) and 1.16 (95% CI: 0.95; 1.42). IDegAsp was well tolerated across age groups. The fast onset of prandial coverage of IAsp in IDegAsp and the ultra-long pharmacokinetic properties of IDeg in IDegAsp were preserved in children and adolescents. Exposure to IAsp and IDeg seemed to be higher in children vs. adults, but no differences were observed in PG lowering effect. IDegAsp could be an alternative treatment option in children and adolescents with T1DM.
