OBJECTIVEOur objective was to characterize diabetes-specific health-related quality of life (D-HRQOL) in a global sample of youth and young adults with type 1 diabetes (T1D) and to identify the main factors associated with quality of life.RESEARCH DESIGN AND METHODSThe TEENs study was an international, cross-sectional study of youth, 8–25 years of age, with T1D. Participants (N = 5,887) were seen in clinical sites in 20 countries across 5 continents enrolled for 3 predetermined age groups: 8–12, 13–18, and 19–25 years of age. To assess D-HRQOL, participants completed the PedsQL Diabetes Module 3.0 and were interviewed about family-related factors. Specifics about treatment regimen and self-management behaviors were collected from medical records.RESULTSAcross all age groups, females reported significantly lower D-HRQOL than did males. The 19–25-year age group reported the lowest D-HRQOL. Multivariate linear regression analyses revealed that D-HRQOL was significantly related to HbA1c; the lower the HbA1c, the better the D-HRQOL. Three diabetes-management behaviors were significantly related to better D-HRQOL: advanced methods used to measure food intake; more frequent daily blood glucose monitoring; and more days per week that youth had ≥30 min of physical activity.CONCLUSIONSIn all three age groups, the lower the HbA1c, the better the D-HRQOL, underscoring the strong association between better D-HRQOL and optimal glycemic control in a global sample of youth and young adults. Three diabetes-management behaviors were also related to optimal glycemic control, which represent potentially modifiable factors for clinical interventions to improve D-HRQOL as well as glycemic control.

AimsTo investigate the efficacy and safety of alirocumab in participants with type 2 (T2D) or type 1 diabetes (T1D) treated with insulin who have elevated LDL cholesterol levels despite maximally tolerated statin therapy.MethodsParticipants at high cardiovascular risk with T2D (n = 441) or T1D (n = 76) and LDL cholesterol levels ≥1.8 mmol/L (≥70 mg/dL) were randomized 2:1 to alirocumab:placebo administered subcutaneously every 2 weeks, for 24 weeks' double‐blind treatment. Alirocumab‐treated participants received 75 mg every 2 weeks, with blinded dose increase to 150 mg every 2 weeks at week 12 if week 8 LDL cholesterol levels were ≥1.8 mmol/L. Primary endpoints were percentage change in calculated LDL cholesterol from baseline to week 24, and safety assessments.ResultsAlirocumab reduced LDL cholesterol from baseline to week 24 by a mean ± standard error of 49.0% ± 2.7% and 47.8% ± 6.5% vs placebo (both P < .0001) in participants with T2D and T1D, respectively. Significant reductions were observed in non‐HDL cholesterol (P < .0001), apolipoprotein B (P < .0001) and lipoprotein (a) (P ≤ .0039). At week 24, 76.4% and 70.2% of the alirocumab group achieved LDL cholesterol <1.8 mmol/L in the T2D and T1D populations (P < .0001), respectively. Glycated haemoglobin and fasting plasma glucose levels remained stable for the study duration. Treatment‐emergent adverse events were observed in 64.5% of alirocumab‐ vs 64.1% of placebo‐treated individuals (overall population).ConclusionsAlirocumab produced significant LDL cholesterol reductions in participants with insulin‐treated diabetes regardless of diabetes type, and was generally well tolerated. Concomitant administration of alirocumab and insulin did not raise any safety concerns (NCT02585778).

AimTo compare alirocumab, a proprotein convertase subtilisin‐kexin type 9 inhibitor, with usual care (UC) in individuals with type 2 diabetes (T2DM) and mixed dyslipidaemia not optimally managed by maximally tolerated statins in the ODYSSEY DM‐DYSLIPIDEMIA trial (NCT02642159).Materials and MethodsThe UC options (no additional lipid‐lowering therapy; fenofibrate; ezetimibe; omega‐3 fatty acid; nicotinic acid) were selected prior to stratified randomization to open‐label alirocumab 75 mg every 2 weeks (with increase to 150 mg every 2 weeks at week 12 if week 8 non‐HDL cholesterol concentration was ≥2.59 mmol/L [100 mg/dL]) or UC for 24 weeks. The primary efficacy endpoint was percentage change in non‐HDL cholesterol from baseline to week 24.ResultsThe randomized population comprised 413 individuals (intention‐to‐treat population, n = 409; safety population, n = 412). At week 24, the mean non‐HDL cholesterol reductions were superior with alirocumab (−32.5% difference vs UC, 97.5% confidence interval −38.1 to −27.0; P < .0001). Overall, 63.6% of alirocumab‐treated individuals were maintained on 75 mg every 2 weeks. Alirocumab also reduced LDL cholesterol (−43.0%), apolipoprotein B (−32.3%), total cholesterol (−24.6%) and LDL particle number (−37.8%) at week 24 vs UC (all P < .0001). Consistent with the overall trial comparison, alirocumab reduced non‐HDL cholesterol to a greater degree within each UC stratum at week 24. The incidence of treatment‐emergent adverse events was 68.4% (alirocumab) and 66.4% (UC). No clinically meaningful effect on glycated haemoglobin, or change in number of glucose‐lowering agents, was seen.ConclusionsIn individuals with T2DM and mixed dyslipidaemia on maximally tolerated statin, alirocumab showed superiority to UC in non‐HDL cholesterol reduction and was generally well tolerated.

These relationships between diabetes education, self-management and glycemic control suggest that diabetes education provides knowledge and skills to optimize self-management, favoring HbA target attainment. Middle East health authorities should search for ways to facilitate access to diabetes education to optimize treatment outcomes.

Eculizumab is an anti-C5 monoclonal antibody approved for rare diseases including atypical haemolytic-uraemic syndrome. The maintenance phase dosing regimen is identical for all adult patients: 1200 mg every 2 weeks. Recent studies reported an overexposure in many patients when considering a target trough concentration range of 50-100 mg/L. The aim of the present work was to validate the feasibility of therapeutic drug monitoring of eculizumab in atypical haemolyticuraemic syndrome patients.Methods: We performed a 2-step prospective multicentre study. In the first phase, we developed a pharmacokinetic population model using data from 40 patients and identified patients for whom a 1-week lengthening of interval between infusions would lead to a trough concentration above 100 mg/L. In the second phase, selected patients were allocated a 1-week extension and eculizumab trough concentrations were monitored. Results:The model confirmed the previously reported influence of bodyweight on elimination clearance and predicted that 36 (90%) patients would be eligible for interval extension. In the second phase of the study, a 1-week lengthening of interval between infusions was performed in 15 patients whose trough concentration at the next visit was predicted with a Bayesian model to be above 100 mg/L. After interval extension, 10 patients (67%) presented measured trough concentrations over 100 mg/L. No biological or clinical recurrence of disease was observed, even in the 5 patients with concentrations below 100 mg/L in whom the initial dosing regimen was resumed. Conclusion:Safe eculizumab interval adjustment is feasible with a PK monitoring.

This paper discusses the results of a survey on the usability of a new half-unit insulin pen, JuniorSTAR ® (CE mark pending, under the responsibility of Haselmeier), in children with type 1 diabetes. Insulin pen devices have advantages over the traditional vial-and-syringe method of insulin delivery, including improved patient satisfaction and adherence, greater ease of use and superior accuracy, especially when delivering small doses of insulin. The accuracy and design of insulin pens is particularly important in the paediatric population.Young children often require half-unit adjustments. As the incidence of type 1 diabetes is expected to increase in the coming years in children less than 5 years old, a higher use of half-unit dosing pens may be anticipated. A survey with JuniorSTAR half-unit insulin pen has shown that it is easy to use, read, carry and dial back. This was confirmed by patients and also by nurses. In conclusion, the JuniorSTAR half-unit pen is well suited to the lifestyle of young people with type 1 diabetes and could help them to gain autonomy to self-inject.

Background: Insulin pens represent a significant technological advancement in diabetes management. While the vast majority have been designed with 1U-dosing increments, improved accuracy and precision facilitated by half-unit increments may be particularly significant in specific patients who are sensitive to insulin. These include patients with low insulin requirements and in those requiring more precise dose adjustments, such as the pediatric patient population. This review summarized functional characteristics of insulin half-unit pens (HUPs) and their effect on user experience. Methods: The literature search was restricted to articles published in English between January 1, 2000, and January 1, 2015. A total of 17 publications met the set criteria and were included in the review. Results: Overall, studies outlined characteristics for 4 insulin HUPs. Based on their functionality, the pens were generally similar and all met the ISO 11608-1 criteria for accuracy. However, some had specific advantageous features in terms of size, weight, design, dialing torque, and injection force. Although limited, the currently available user preference studies in children and adolescents with diabetes and their carers suggest that the selection of an HUP is likely to be influenced by a combination of factors such as these, in addition to the prescribed insulin and dosing regimen. Conclusions: Insulin HUPs are likely to be a key diabetes management tool for patients who are sensitive to insulin; specific pen features may further advance diabetes management in these populations.
