Background: Faster-acting insulin aspart (faster aspart) is insulin aspart (IAsp) in a new formula-

Youth with type 1 diabetes (T1D) infrequently achieve HbA1c targets. Therefore, this placebo-controlled, randomized, crossover study was set up to assess the safety, effect and pharmacokinetics of a single dose of 10 mg dapagliflozin (DAPA) as add-on to insulin in relationship to HbA1c in youth. A total of 33 youths (14 males, median age 16 years, diabetes duration 8 years) were included and stratified into 3 baseline HbA1c categories (<7.5%, 7.5%-9.0% or >9.0; n = 11 each). During the study period of 24 hours, intravenous insulin administration and glucose-infusion kept blood glucose levels at 160 to 220 mg/dL. DAPA reduced mean insulin dose by 13.6% ( P < .0001 by ANOVA) and increased urinary glucose excretion by 610% (143.4 vs 22.4 g/24 h; P < .0001), both irrespective of baseline HbA1c. Six independent episodes in 6 patients with plasma ß-hydroxybutyrate levels between ≥0.6 and <1.0 mmol/L were observed after liquid meal challenges, 5 episodes in the DAPA group and 1 in the placebo group. This study provides a proof-of-concept, irrespective of preexisting HbA1c levels, for adjunct SGLT2-inhibitor therapy in the paediatric age group by lowering insulin dose and increasing glucose excretion.

The MD-Logic system demonstrated a safe and efficient profile during overnight use by children, adolescents and adults with type 1 diabetes and, therefore, provides an effective means of mitigating the risk of nocturnal hypoglycaemia.

The objectives were to evaluate the current prevalence of lipoatrophy at insulin injection sites in young patients with type 1 diabetes. Standardized examination of insulin injection sites in all 678 patients with type 1 diabetes treated in 2013 in our outpatient clinic were conducted. In case of lipoatrophy photo documentation and standardized interview with parents and patients were performed. We identified a total of 16 patients (43.8% male) with lipoatrophy (overall prevalence 2.4%). The current mean age (±SD) of the affected patients was 14.4 ± 3.9 years, age and diabetes duration at onset of lipoatrophy were 11.5 ± 3.8 years and 5.4 ± 3.6 years, respectively. All patients were using analogs at the onset of lipoatrophy. In all, 14 of 16 patients (87.5%) were on insulin pump compared with 52% without lipoatrophy (P = .0018). The use of steel needle and Teflon catheter was equal between the pump patients. Concomitant autoimmune diseases were present in 37.5% of the patients (thyroiditis: n = 3, thyroiditis and celiac disease: n = 2, celiac disease: n = 1) compared with 15.0% in those without lipoatrophy (P = .0128). Lipoatrophy was present in young patients treated with modern insulins and pumps; however, the prevalence was relatively low as expected with the use of modern insulins. Our data may support the hypothesis that a constant mechanical element such as a subcutaneous catheter may trigger the development of lipoatrophy, particularly in those patients with more than 1 autoimmune disease.
