Aims The long-acting insulin analogue glargine reduces nocturnal hypoglycaemia and stabilizes morning blood glucose levels in patients with Type 1 diabetes (T1DM) on multiple injection therapy. However, young children may not tolerate such intensive insulin regimens. We investigated the effects of glargine in various three-injections-daily insulin combinations on 24-h glucose control in prepubertal children. Methods Seventeen T1DM prepubertal children (10 boys), median age 10.2 years (range 6.0–12.4), glycated haemoglobin (HbA1c) 8.8% (6.8–11.5) were recruited to a randomized, open-label, cross-over study. After a 2-week run-in period (with NPH pre-bed), every child underwent three different 3-week treatment blocks in random order. All treatment blocks included glargine pre-bed, but used different morning insulins: block 1, soluble only; block 2, soluble + NPH; block 3, aspart + NPH. Continuous glucose monitoring was performed for 3 days at the end of the run-in and each treatment block. Results Compared with the run-in period on NPH, the three glargine treatment blocks were associated with lower ( P < 0.0001) and less variable ( P < 0.05) pre-breakfast glucose levels, and with an 8–15% reduction in total daily insulin dose ( P < 0.0001). Risk of nocturnal hypoglycaemia detected by continuous glucose monitoring varied significantly between the three glargine treatment blocks, and was lowest when children were given aspart + NPH in the morning (block 3). Conclusion Insulin glargine pre-bed can be used in three-injections-daily regimens in prepubertal children to lower and stabilize pre-breakfast glucose levels. However, to avoid the risk of nocturnal hypoglycaemia, the pre-bed glargine dose should be lowered by giving a further long-acting insulin, such as NPH, in the morning. [ABSTRACT FROM AUTHOR]

Aim. To evaluate the prevalence of overweight and obesity in paediatric type 1 diabetes (T1D) subjects, based on four commonly used reference populations. Methods. Using WHO, IOTF, AGA (German pediatric obesity), and KiGGS (German Health Interview and Examination Survey for Children and Adolescents) reference populations, prevalence of overweight (≥90th percentile) and obesity (≥97th percentile) and time trend between 2000 (n = 9,461) and 2013 (n = 18,382) were determined in 2–18-year-old T1D patients documented in the German/Austrian DPV database. Results. In 2000, the overweight prevalence was the highest according to IOTF (22.3%), followed by WHO (20.8%), AGA (15.5%), and KiGGS (9.4%). The respective rates in 2013 were IOTF (24.8%), WHO (22.9%), AGA (18.2%), and KiGGS (11.7%). Obesity prevalence in 2000 was the highest according to WHO (7.9%), followed by AGA (4.5%), IOTF (3.1%), and KiGGS (1.8%). In 2013, the respective rates were WHO (9.6%), AGA (6.2%), IOTF (4.5%), and KiGGS (2.6%). Overall, the prevalence of overweight and obesity increased from 2000 to 2006 (p < 0.001) but showed stabilization thereafter in girls and overweight in boys. Conclusion. Overweight and obesity prevalence in T1D subjects differs significantly if it is assessed by four separate reference populations. More detailed assessment of each child is required to determine obesity-related risks. [ABSTRACT FROM AUTHOR]

Background: Several genetic syndromes are associated with diabetes mellitus (DM). This study aimed to analyse data from the DPV database with regard to frequency, treatment strategies and long-term complications in paediatric DM patients with genetic syndromes, including Turner syndrome (TS), Prader-Willi syndrome (PWS), Friedreich ataxia (FA), Alström syndrome (AS), Klinefelter syndrome (KS), Bardet-Biedl syndrome (BBS), Berardinelli-Seip syndrome (BSS) and Down syndrome (DS). Methods: Longitudinal data for 43 521 patients with DM onset at age < 20 years were collected from 309 treatment centres in Germany and Austria using the DPV software. Data included anthropometric parameters, type of diabetes, mean age, age at diabetes onset, daily insulin dose, HbA 1c , micro- and macroalbuminuria, retinopathy and dyslipidaemia. Descriptive statistics and standard statistical tests were used for data analysis. Results: In total, 205 DM patients had one of the following syndromes: DS (141 patients), TS (24), PWS (23), FA (5), AS (5), KS (4), BBS (2) and BSS (1). Diabetes-specifi c antibodies were positive in the majority of patients with DS, TS and FA. Conclusion: Despite the well-known association between DM and certain syndromic disorders, the number of affected patients in the German and Austrian paediatric diabetic population is very low. Nevertheless, physicians should be aware of syndromic forms of diabetes. Joint multicentre analyses are needed to draw relevant conclusions. [ABSTRACT FROM AUTHOR]
