OBJECTIVE:To investigate rates and risk factors of hospital admission for diabetic ketoacidosis (DKA) or severe hypoglycemia in young patients with established type 1 diabetes.DESIGN:In total, 31,330 patients with type 1 diabetes (median age 12.7 years) from the Diabetes Patienten Verlaufsdokumentation (DPV) Prospective Diabetes Registry treated between 2011 and 2013 in Germany were included.METHODS:Admission rates for DKA (pH < 7.3 or bicarbonate <15 mmol/l) and severe hypoglycemia (requiring assistance from another person) were calculated by negative binomial regression analysis. Associations of DKA or hypoglycemia with patient and treatment characteristics were assessed by multivariable regression analysis.RESULTS:The mean admission rate for DKA was 4.81/100 patient-years (95% CI, 4.51-5.14). The highest DKA rates were observed in patients with HbA1c ≥ 9.0% (15.83 (14.44-17.36)), age 15-20 years (6.21 (5.61-6.88)) and diabetes duration of 2-4.9 years (5.60 (5.00-6.27)). DKA rate was higher in girls than in boys (5.35 (4.88-5.86) vs 4.34 (3.95-4.77), P = 0.002), and more frequent in migrants than in non-migrants (5.65 (4.92-6.49) vs 4.57 (4.23-4.93), P = 0.008). The mean admission rate for severe hypoglycemia was 1.45/100 patient-years (1.30-1.61). Rates were higher in migrants compared to non-migrants (2.13 (1.72-2.65) vs 1.28 (1.12-1.47), P < 0.001), and highest in individuals with severe hypoglycemia within the preceding year (17.69 (15.63-20.03) vs patients without preceding hypoglycemia 0.42 (0.35-0.52), P < 0.001). Differences remained significant after multivariable adjustment.CONCLUSIONS:The identification of at-risk individuals for DKA (patients with high HbA1c, longer diabetes duration, adolescents, girls) and for severe hypoglycemia (patients with preceding severe hypoglycemia, migrants) may facilitate targeted diabetes counselling in order to prevent these complications.

Background/Aims: Lipoatrophy (LA) is a rare, possibly under-recognised side effect of insulin treatment of unclear aetiology. The aim of this study was to describe the characteristics of patients with type 1 diabetes (T1D) who have LA and to explore the relationship between LA and other autoimmune diseases based on the hypothesis that additional autoimmune phenomena are more prevalent in T1D patients with LA. Methods: This was a cross-sectional observational study of T1D patients with LA in comparison to T1D patients without LA who are registered with the Diabetes Patienten-Verlaufsdokumentationssystem database of 241,650 patients in Germany and Austria. Results: Hashimoto's thyroiditis and coeliac disease were more prevalent in patients with LA (p < 0.001 for both). LA was associated with an increased risk of Hashimoto's thyroiditis and coeliac disease in female patients [odds ratio (OR) 2.5, p = 0.003, and OR 3.1, p = 0.02, respectively]. This relationship persisted after adjustment for current age, duration of diabetes and calendar year of treatment (OR 2.7, p = 0.002, and OR 3.5, p = 0.01, respectively). Conclusion: These findings support the hypothesis that an immune complex-mediated inflammatory process may be important in the development of LA.

OBJECTIVE:To estimate diabetes-related direct health care costs in pediatric patients with early-onset type 1 diabetes of long duration in Germany.RESEARCH DESIGN AND METHODS:Data of a population-based cohort of 1,473 subjects with type 1 diabetes onset at 0-4 years of age within the years 1993-1999 were included (mean age 13.9 (SD 2.2) years, mean diabetes duration 10.9 (SD 1.9) years, as of 31.12.2007). Diabetes-related health care services utilized in 2007 were derived from a nationwide prospective documentation system (DPV). Health care utilization was valued in monetary terms based on inpatient and outpatient medical fees and retail prices (perspective of statutory health insurance). Multiple regression models were applied to assess associations between direct diabetes-related health care costs per patient-year and demographic and clinical predictors.RESULTS:Mean direct diabetes-related health care costs per patient-year were €3,745 (inter-quartile range: 1,943-4,881). Costs for glucose self-monitoring were the main cost category (28.5%), followed by costs for continuous subcutaneous insulin infusion (25.0%), diabetes-related hospitalizations (22.1%) and insulin (18.4%). Female gender, pubertal age and poor glycemic control were associated with higher and migration background with lower total costs.CONCLUSIONS:Main cost categories in patients with on average 11 years of diabetes duration were costs for glucose self-monitoring, insulin pump therapy, hospitalization and insulin. Optimization of glycemic control in particular in pubertal age through intensified care with improved diabetes education and tailored insulin regimen, can contribute to the reduction of direct diabetes-related costs in this patient group.

OBJECTIVE:Initiation of continuous subcutaneous insulin therapy (CSII) requires an appropriate basal rate profile. Different approaches exist; however, there is a lack of evidence-based recommendations, especially in young children. STUDY DESIGN:In this large multicenter survey, 5941 CSII patients from the German/Austrian prospective documentation system (DPV) were analyzed. Patients were divided into four age groups: <6 yr (n = 837), 6 to <12 yr (n = 1739), 12 to <18 yr (n = 2985) and 18 to <25 yr (n = 380). Basal insulin requirement and diurnal distribution were evaluated based on the most recent documentation for each patient. RESULTS:Basal insulin requirement differed significantly between the four age groups (<6: 0.25 ± 0.12; 6 to <12: 0.33 ± 0.12; 12 to <18: 0.43 ± 0.15; 18 to <25: 0.35 ± 0.13 U/kg; p < 0.001). Circadian insulin profiles were markedly different between the younger and older age groups. In addition to age, longer diabetes duration, female gender, higher HbA1c and lower body mass index standard deviation score (BMI-SDS) were related to higher basal insulin requirement per kilogram of body weight. CONCLUSIONS:Age of the patient is the primary factor that influences both total daily requirement and circadian distribution of basal insulin in CSII. Experience from a large database may therefore facilitate the initiation of pump therapy in pediatric patients.

OBJECTIVE:The aim of this data analysis was to ascertain the type and prevalence rate as well as age and sex distribution of cardiovascular risk factors in type 1 diabetic patients up to 26 years of age.RESEARCH DESIGN AND METHODS:Cardiovascular risk factors such as obesity, hypertension, dyslipidemia, poor glycemic control, and smoking were analyzed in 27,358 patients who were divided into three groups (prepubertal, pubertal, and adult) using specifically designed diabetes software for prospective disease documentation.RESULTS:More than half of the patients per age-group had at least one cardiovascular risk factor. Two risk factors were age dependently found in 6.2-21.7% and three or four risk factors in 0.5-4.7%. Elevated values of HbA(1c), total cholesterol, and BMI were found most frequently. Hypertension, smoking, and HDL cholesterol were observed more frequently in males, and elevated BMI, total cholesterol, and LDL cholesterol more often in females. Although 28.6% of the patients had dyslipidemia, merely 0.4% of them received medical treatment, and of the 8.1% of the patients with hypertension, only 2.1% of them were given antihypertensive medication.CONCLUSIONS:With increasing age, a greater number of patients with cardiovascular risk factors were observed. Significant sex differences were seen in the majority of risk factors. Despite the high prevalence of risk factors, only a small minority of patients received antihypertensive or lipid-lowering treatment. Early identification, prevention, and treatment of additional risk factors seem to be necessary, particularly in light of the high incidence of future cardiovascular disease.

The cardiovascular risk factors hypertension and dyslipidemia clearly predict morbidity and mortality.Data on the prevalence before, during and after puberty, and on the rela- tion to gender and degree of overweight, pro-vide a basis for early intervention. 65 cen- ters specialised in obesity care contributed standardized, anonymized data documented by the "APV"-software (see http://www.a-p-v.de). 6751 patients were prepubertal (age <12years), 7344 pubertal (12–14years) and 774 were young adults (16–40years). A total of 14869 patients were available for analysis. BMI was evaluated according to age- and sex-standardized reference values and classified as normal weight, overweight (>90. perc), obesity (>97.perc) or extreme obesity (>99.5. perc). 921 subjects were normalweight (6.2%), 2582 (17.4%) were overweight, 6837 (45.9%) were obese and 4529 (30.5%) were extremely obese based on German references (Kromeyer-Hauschild/Nationale Verzehrstudie). Blood pressure was evaluated based on 2nd Task Force recommendations. A cholesterol >200, HDL <35, LDL >130 and triglycerides >150mg/dl were considered abnormal according to Am. Heart Association guidelines. In multivariate logistic regression analysis, the presence of hypertension was significantly related to male gender (OR 1.2), overweight (OR 1.7), obesity (OR 2.8) or extreme obesity (OR 5.7), as well as to puberty (OR 1.3) or adulthood (OR 2.4).

So far in Europe, no studies have been published on the structuring of medical care for obese children and adolescents. Besides anthropometric parameters, evaluations of the cardiovascular risk factors hypertension, dyslipidaemia, impaired glucose metabolism and treatment modalities were documented in a standardised multicentre evaluation survey (APV) of 18 primarily outpatient and nine rehabilitation institutions. In total, 3837 children (aged 2–20 years) took part in the years 2000 up to March 2003, of whom 1985 were treated in outpatient institutions and 1852 in rehabilitation institutions. Of these children, 10% were overweight, 37% obese, 49% extremely obese and 4% of normal weight at initial presentation. The frequencies of diagnostic procedures performed and documented were low (measurement of blood pressure 43%, lipids 40%, glucose metabolism 21%). In the subgroup of obese children who were screened for cardiovascular risk factors, 23% suffered from hypertension, 11% displayed increased cholesterol, 9% increased low-density lipoprotein-cholesterol, 29% increased triglycerides, 11% decreased high-density lipoprotein-cholesterol and 6% had impaired glucose metabolism. Conclusion: despite the high prevalence of cardiovascular risk factors in obese children and adolescents confirmed in this report, diagnostic procedures failed in a considerable percentage even in specialised treatment centres for obese children and adolescents. In future, the feedback based on standardised evaluation of diagnostic and treatment procedures should aim to improve the quality of medical care.
