ABSTRACT
Purpose: To compare the changes in body weight and glycemic control before and during the COVID-19 pandemic in people with type 1 diabetes (T1D). Methods: In 47,065 individuals with T1D from the German Diabetes Prospective Follow-up Registry (DPV), we compared the adjusted mean changes in BMI-Z-scores and HbA1c as well as the distribution of individual changes between four periods from March 2018 to February 2022, by sex and age group (4- < 11, 11- < 16, 16-50 years). Results: At population level, the only significant pandemic effects were a slight increase in BMI Z-score in prepubertal children (girls: + 0.03 in the first COVID year vs. before, P < 0.01; boys: + 0.04, P < 0.01) as well as a stabilization of HbA1c in all subgroups or even improvement in women (- 0.08%, P < 0.01). At individual level, however, heterogeneity increased significantly (p < 0.01), especially in children. More prepubertal children gained weight (girls: 45% vs. 35% before COVID; boys: 39% vs. 33%). More pubertal girls lost weight (30% vs. 21%) and fewer gained weight (43% vs. 54%). More children had a decreasing HbA1c (prepubertal group: 29% vs. 22%; pubertal girls: 33% vs. 28%; pubertal boys: 32% vs. 25%) and fewer had increasing values. More women had stable HbA1c and fewer had increasing values (30% vs. 37%). In men, no significant changes were observed. Conclusion: This real-world analysis shows no detrimental consequences of the two first COVID years on weight and HbA1c in T1D on average, but reveals, beyond the mean trends, a greater variability at the individual level.
ABSTRACT
CONTEXT: Burosumab has been approved for the treatment of children and adults with X-linked hypophosphatemia (XLH). Real-world data and evidence for its efficacy in adolescents are lacking. OBJECTIVE: To assess the effects of 12 months of burosumab treatment on mineral metabolism in children (aged <12 years) and adolescents (aged 12-18 years) with XLH. DESIGN: Prospective national registry. SETTING: Hospital clinics. PATIENTS: A total of 93 patients with XLH (65 children, 28 adolescents). MAIN OUTCOME MEASURES: Z scores for serum phosphate, alkaline phosphatase (ALP), and renal tubular reabsorption of phosphate per glomerular filtration rate (TmP/GFR) at 12 months. RESULTS: At baseline, patients showed hypophosphatemia (-4.4 SD), reduced TmP/GFR (-6.5 SD), and elevated ALP (2.7 SD, each P < .001 vs healthy children) irrespective of age, suggesting active rickets despite prior therapy with oral phosphate and active vitamin D in 88% of patients. Burosumab treatment resulted in comparable increases in serum phosphate and TmP/GFR in children and adolescents with XLH and a steady decline in serum ALP (each P < .001 vs baseline). At 12 months, serum phosphate, TmP/GFR, and ALP levels were within the age-related normal range in approximately 42%, 27%, and 80% of patients in both groups, respectively, with a lower, weight-based final burosumab dose in adolescents compared with children (0.72 vs 1.06 mg/kg, P < .01). CONCLUSIONS: In this real-world setting, 12 months of burosumab treatment was equally effective in normalizing serum ALP in adolescents and children, despite persistent mild hypophosphatemia in one-half of patients, suggesting that complete normalization of serum phosphate is not mandatory for substantial improvement of rickets in these patients. Adolescents appear to require lower weight-based burosumab dosage than children.

AIMS: (1) To describe the population of patients with type 1 diabetes (T1DM) using the rapid-acting insulin analogue glulisine versus lispro and aspart during continuous subcutaneous insulin infusion (CSII); (2) to describe insulin relative effectiveness based on hemoglobin A1c (HbA1c), fasting blood glucose (FBG) and dose; (3) to determine rates of hyperglycemia, hypoglycemia, and diabetic ketoacidosis (DKA). METHODS: The analysis used March 2021 data from the Diabetes-Patienten-Verlaufsdokumentation registry, which contains data of 618,903 patients with diabetes. Patients were propensity-matched by age, sex, and diabetes duration. RESULTS: Overall, 42,736 patients of any age were eligible for analysis based on insulin pump usage with either glulisine (N = 707) or lispro/aspart (N = 42,029) between 2004 and 2020. Patients receiving glulisine were older (median 20.0 vs. 16.2 years), equally often male (47.2% vs. 47.8%) and had a longer diabetes duration (median 9.4 vs. 7.4 years). After propensity score matching, 707 pairs remained (total N = 1414). Patient characteristics between groups were similar. Achieved HbA1c values were also comparable: 8.04%, 64 mmol/mol versus 7.96%, 63 mmol/mol for glulisine and lispro/aspart [LS mean difference 0.08 (95%CI - 0.08, 0.25)]. FBG was 9.37 mmol/L (168.9 mg/dL) and 9.58 mmol/L (172.6 mg/dL) in the glulisine and lispro/aspart groups [LS mean diff. - 0.21; (95%CI - 1.13, 0.72)]. Total daily insulin doses and prandial to total insulin ratios were also similar. Glulisine group patients had higher rates of lipodystrophy (0.85% vs. 0.71%) (LS mean diff. 0.18 [95% CI - 1.01, 1.38]) and non-severe DKA (3.11% vs. 0.57%; p = 0.002). Fewer patients in the glulisine group had severe hypoglycemic events (7.66 vs. 9.09; p = 0.333) and severe ketoacidosis events (0.57% vs. 1.56%; p = 0.082) but more had hypoglycemic coma events (p = 0.773), although the differences were not statistically significant. CONCLUSIONS: Insulin glulisine had comparable glucose control to lispro/aspart. The use of glulisine was less frequent in the present analysis compared to the previous trials.

CONTEXT: Autoimmune diseases affect ~8% of the population. Type 1 diabetes mellitus (T1DM) is linked to other autoimmune diseases (AIDs), such as autoimmune thyroid disease or Addison's disease (AD), that may impact diabetes therapy and outcome. OBJECTIVE: To analyze demographic and clinical characteristics of other AIDs in T1DM from a large standardized registry, the Prospective Diabetes Follow-up Registry (DPV). METHODS: We searched the registry for T1DM with the additional diagnosis of Hashimoto's thyroiditis (HT), Graves' disease (GD), and/or AD. T1DM with other AIDs (nâ =â 6166, 5.4%) were compared with isolated T1DM (nâ =â 107 457). For group comparisons, we used multivariable regression models with age, sex, diabetes duration, migration background, and type of insulin regimen as basic adjustments (microvascular endpoints: additionally adjusted for glycated hemoglobin). RESULTS: Patients with additional AIDs were more often female (54.7 vs 32.0%, Pâ <â .001) and had a longer diabetes duration (7.9 [4.2-12.5] vs 6.7 [2.7-12.9] years, Pâ <â .001). After adjustment, daily insulin dosage was higher in AD and HT than in isolated T1DM (0.858â ±â 0.032 and 0.813â ±â 0.005 vs 0.793â ±â 0.001 IU/kg per day). Retinopathy was less common in HT (1.5%), whereas it was more frequent in GD (3.1%) than in isolated T1DM (1.8%). In both GD and HT, microalbuminuria occurred less often (10.6% and 14.3% vs 15.5%) and neuropathy (2.1% and 1.8% vs 0.8%) was more common than in isolated T1DM. All P < .05. CONCLUSION: T1DM with additional AIDs show heterogeneous differences compared with isolated T1DM. T1DM plus AD or HT requires more insulin. Further, the rate of neuropathy is higher in HT or GD, whereas the rate of microalbuminuria is lower.

Neonatal screening for congenital primary hypothyroidism (CH) may not distinguish between transient (TCH) and permanent dysfunction (PCH), causing potential overtreatment and concerns in affected families. To specify the indication for interruption of therapy, we analysed the German registry "HypoDok" for infants with CH, which oversees 1625 patients from 49 participating centres in Germany and Austria from 1997 until today. A total of 357 patients with a thyroid gland in loco typico were identified and retrospectively grouped according to cessation (TCH, n = 24) or continuation (PCH, n = 333) of L-thyroxine (L-T4) treatment at 2 years of age. The receiver operating characteristic (ROC) analysis was performed to identify cutoffs predicting TCH by screening TSH concentrations and L-T4 dosages. Gestational ages, birth weights and prevalence of associated malformations were comparable in both groups. The cutoff screening TSH concentration was 73 mU/L. The cutoff daily L-T4 dosage at 1 year was 3.1 µg/kg (90% sensitivity, 63% specificity; 36 µg/day) and at 2 years of age 2.95 µg/kg (91% sensitivity, 59% specificity; 40 µg/day). At 2 years of age, specificity (71%) increased when both of these parameters were considered together.Conclusion: The decision to continue or cease L-T4 treatment at 2 years of age in CH patients diagnosed in neonatal screening may be based on their screening TSH concentrations and individual L-T4 dosages at 1 and 2 years of age. Thus, TCH and PCH may be distinguished; overtreatment avoided; and affected families reassured. What is Known: ⢠The course of congenital primary hypothyroidism may be transient, causing potential overtreatment. ⢠The dose of l-thyroxine at 1 or 2 years of age may predict a transient course of primary congenital hypothyroidism. What is New: ⢠TSH screening concentration and l-thyroxine dosages at 1 and 2 years of age represent reliable predictors for transient congenital primary hypothyroidism with higher sensitivity and specificity when considered together in order to select eligible patients who qualify for treatment withdrawal.

The aim of the study was to explore the metabolic characteristics and outcome parameters in youth with type 1 diabetes and anxiety disorders. HbA1c levels, rates of severe hypoglycemia, diabetic ketoacidosis (DKA), and hospital admission in children, adolescents, and young adults with type 1 diabetes and an anxiety disorder from 431 diabetes-care-centers participating in the nationwide German/Austrian/Swiss/Luxembourgian diabetes survey DPV were analyzed and compared with youth without anxiety disorders. Children, adolescents, and young adults with type 1 diabetes and anxiety disorders (n = 1325) had significantly higher HbA1c (8.5% vs. 8.2%), higher rates of DKA (4.2 vs. 2.5 per 100 patient-years), and higher hospital admission rates (63.6 vs. 40.0 per 100 patient-years) than youth without anxiety disorders (all p < 0.001). Rates of severe hypoglycemia did not differ. Individuals with anxiety disorders other than needle phobia (n = 771) had higher rates of DKA compared to those without anxiety disorders (4.2 vs. 2.5 per 100 patient-years, p = 0.003) whereas the rate of DKA in individuals with needle phobia (n = 555) was not significantly different compared to those without anxiety disorders. Children, adolescents, and young adults with anxiety disorders other than needle phobia had higher hospitalization rates (73.7 vs. 51.4 per 100 patient-years) and more inpatient days (13.2 vs. 10.1 days) compared to those with needle phobia (all p < 0.001). Children, adolescents, and young adults with type 1 diabetes and anxiety disorders had worse glycemic control, higher rates of DKA, and more hospitalizations compared to those without anxiety disorders. Because of the considerable consequences, clinicians should screen for comorbid anxiety disorders in youth with type 1 diabetes.

Friedreich ataxia (FRDA) is a multisystem autosomal recessive disease with progressive clinical course involving the neuromuscular and endocrine system. Diabetes mellitus (DM) is one typical non-neurological manifestation, caused by beta cell failure and insulin resistance. Because of its rarity, knowledge on DM in FRDA is limited. Based on data from 200,301 patients with DM of the German-Austrian diabetes registry (DPV) and two exemplary patient reports, characteristics of patients with DM and FRDA are compared with classical type 1 or type 2 diabetes. Diabetes phenotype in FRDA is intermediate between type 1 and type 2 diabetes with ketoacidosis being frequent at presentation and blood glucose levels similar to T1Dm but higher than in T2Dm (356⯱â¯165 and 384⯱â¯203â¯mg/dl). 63.2% of FRDA patients received insulin monotherapy, 21% insulin plus oral antidiabetics and 15.8% lifestyle change only, applying similar doses of insulin in all three groups. FRDA patients did not show overweight and HbA1c levels were even lower than in T1Dm or T2Dm patients, respectively, indicating good overall diabetes control. FRDADm can be controlled by individualized treatment regimen with insulin or oral antidiabetics. Patients with DM in FRDA may show a relevant risk to ketoacidotic complications, which should be avoided.

OBJECTIVE: To examine glycemic control in youth with type 1 diabetes (T1D) who switched from multiple daily injections (MDI) to a tubeless insulin pump (Omnipod Insulin Management System, Insulet Corporation, Billerica, Massachusetts) compared to patients who continued MDI therapy over a 3-year time period. RESEARCH DESIGN AND METHODS: This retrospective analysis of the German/Austrian Diabetes Patienten Verlaufsdokumentation registry included data from 263 centers and 2529 patients <20 years (n = 660 tubeless insulin pump; n = 1869 MDI) who initiated treatment on a tubeless insulin pump as of January 1, 2013 and had 1 year of data preswitch from MDI and 3 years of data postswitch to a tubeless pump. Outcomes included the change in glycated hemoglobin (HbA1c), insulin dose, and body mass index (BMI) SD score (SDS). RESULTS: Youth with T1D who switched from MDI therapy to a tubeless insulin pump showed better glycemic control at 1 year compared to patients who continued MDI treatment, adjusted mean ± SE: 7.5% ± 0.03% (58 mmol/mol) vs 7.7% ± 0.02% (61 mmol/mol); P < .001, with no between-group difference at 2 and 3 years. Total daily insulin dose was lower (P < .001) in the tubeless insulin pump group, 0.80 ± 0.01, 0.81 ± 0.01, and 0.85 ± 0.01 U/kg, vs the MDI group, 0.89 ± 0.01, 0.94 ± 0.01, and 0.97 ± 0.01 U/kg, at 1, 2, and 3 years, respectively (all P < .001). BMI SDS increased in both groups and was not different over time. CONCLUSIONS: Treatment with a tubeless insulin pump in youth with T1D was associated with improvements in glycemic control compared to MDI after 1 year and appears to be an effective alternative to MDI.

Context While an association between PCOS and type 2 diabetes is well established, to date there have been few data on clinical care of type 1 diabetes (T1D) patients with PCOS. Objective The aim of our study was to characterize T1D patients with the comorbidity of PCOS within the DPV cohort with regard to diabetes phenotype, therapy and metabolic control. Design and Setting Clinical data from the prospective German/Austrian DPV cohort on patients with T1D and documented PCOS (n=76) were compared to female T1D controls (n=32,566) in reproductive age. Results The age at T1D manifestation in PCOS patients was later than in the control group (14.9±8.2 vs. 11.8±7.0 years, p<0.001). PCOS patients had higher BMI-SDS (0.92±0.11 vs. 0.38±0.01, p<0.001), metformin and oral contraceptives were used more frequently (p<0.001). A1c levels were significantly lower (7.92 +/- 0.23% vs. 8.43±0.01%, p<0.05) despite of lower insulin requirements (0.76±0.04 IU/kg/d vs. 0.84±0.00 IU/kg/d, p<0.05). In the PCOS group, higher rates of dyslipidemia (63.4 vs. 48.7%, p =0.032) and thyroid disorders (42.2% vs. 21.2%, p<0.001) were present. Discussion While patients with T1D and comorbid PCOS showed features of a "type 1.5 diabetes" phenotype, insulin requirements per kg body weight were not higher and metabolic control was better, which could be explained only partially by additional metformin therapy. A more precise genetic and metabolic characterisation of these patients is needed to answer open questions on the underlying autoimmune process and residual ß-cell function.

BACKGROUND: The latest American Association of Clinical Endocrinologists/American College of Endocrinologists consensus statement published in 2014 does not recommend continuous subcutaneous insulin infusion (CSII) in patients with mental health problems. This study investigated the use and discontinuation of CSII in daily routine care of type 1 diabetes (T1D) patients with or without comorbid mental disorders. MATERIALS AND METHODS: Insulin-treated T1D patients (n = 48,700) between 5 and 30 years of age (median [interquartile range], 15.6 [12.0-17.7] years) from the German/Austrian diabetes patient follow-up registry (DPV) were studied. A comorbid diagnosis and/or specific treatment of mental disorder was documented in 3,158 (6.5%) patients: attention-deficit hyperactivity disorder (ADHD), n = 1,352; depression, n = 692; eating disorders, n = 395; needle phobia, n = 319; anxiety/obsessive compulsive disorder (OCD), n = 231; and psychosis and/or neuroleptic medication, n = 169. Multivariable logistic regression with age, sex, diabetes duration, and migration background as independent variables was used to compare groups. RESULTS: After adjustment for confounders, use of CSII was more common in patients with depression (41.5%), anxiety/OCD (41.4%), or needle phobia (75.8%) compared with patients without mental disorders (34.6%) (each P < 0.05). By contrast, psychotic patients (26.2%, P < 0.05) used CSII less often, and patients with ADHD (36.3%) or eating disorders (33.9%) used it with a similar frequency. Compared with patients without mental disorders (5.1%), the rate of CSII discontinuation was higher in patients with ADHD (9.7%), depression (8.2%), or eating disorders (10.0%) (P < 0.05, respectively) but similar in patients with anxiety/OCD (6.0%), psychosis (4.2%), or needle phobia (5.3%). CONCLUSIONS: In routine diabetes care, CSII use and discontinuation vary widely among T1D patients with mental disorders and indicate clear differences from the latest recommendations.

UNLABELLED: The aim of this study was to characterize the phenotype and treatment of young patients (manifestation <30 years) with diabetes of mitochondrial origin (DMO), based on the German/Austrian DPV (Diabetes Patienten Verlaufsdokumentation) registry. Only 13 (0.02 %) of all patients with diabetes in this cohort were identified with DMO, mainly due to the Kearns-Sayre (n = 5), Pearson (n = 3), or mitochondrial myopathy, encephalomyopathy, lactic acidosis, and stroke-like episodes (MELAS) syndrome (n = 2). The onset of DMO (14.2, interquartile range (IQR) 7.1-16 years) was later than diabetes onset in individuals with T1D but earlier than in T2D. At manifestation, patients exhibited a mild elevation of blood glucose concentrations (251, IQR 178-299 mg/dl) without ketoacidosis. They had lower body mass index (BMI) values (-1.39 ± 0.28 kg/m(2)) than peers with T1D or T2D (p < 0.0001) and higher triglycerides (211, IQR 134-574 mg/dl) than in T1D (p = 0.04) while there was a high rate of dyslipidemia (86 %). Insulin requirements (0.58, IQR 0.37-0.90 U/kg/d) were between T1D and T2D while glucometabolic control (glycated hemoglobin A1c (HbA1c) 7.4 ± 0.52 %) in DMO was comparable to age-matched T2D and stable over a 5-year follow-up. CONCLUSION: Primary mitochondrial disorders are a rare cause of juvenile diabetes and likely to be underdiagnosed. As there is clinical overlap with T1D and T2D, dyslipidemia and low body weight may help to identify further DMO cases. WHAT IS KNOWN: ⢠In adults diabetes of mitochondrial origin (DMO) is a rare cause of non-autoimmune diabetes, affecting about 0.8 % of diabetes cases. ⢠Common features are a maternal family history of diabetes, hearing loss and neurological abnormalities. What is New: ⢠In our juvenile cohort 0.02 % of diabetes patients (age < 30 years) were affected by DMO, while Kearns Sayre, MELAS and Pearson syndrome were the most frequent entities. ⢠Juvenile DMO patients exhibited dyslipidemia, higher triglycerides and a lower BMI than peers with T1D or T2D, while some patients also showed retinal changes.

OBJECTIVE: The objective of this study was to explore metabolic risk factors and glycemic control in youth with type 1 diabetes treated with typical or atypical antipsychotics. RESEARCH DESIGN AND METHODS: Data for 60,162 subjects with type 1 diabetes up to the age of 25 years registered in the nationwide German/Austrian Diabetes Survey were included in the analysis. BMI; HbA1c; treatment strategy; prevalence of hypertension, dyslipidemia, microalbuminuria, and retinopathy; frequency of hypoglycemia and diabetic ketoacidosis (DKA); and immigrant status among subjects treated with typical or atypical antipsychotics were compared with those without antipsychotic medication and analyzed by regression analysis. RESULTS: A total of 291 subjects with type 1 diabetes (median diabetes duration 7.2 years) received antipsychotic medications (most commonly risperidone). Subjects treated with antipsychotics had a higher BMI (P = 0.004) and dyslipidemia was more frequent (P = 0.045) compared with subjects not receiving antipsychotic medication. Frequencies of severe hypoglycemia and DKA were significantly higher in subjects receiving antipsychotics (P < 0.001). The prevalences of hypertension, microalbuminuria, and retinopathy were not different. In subjects treated with typical antipsychotics, glycemic control did not differ compared with those who did not receive antipsychotic medications. By contrast, subjects treated with atypical antipsychotics had higher HbA1c levels (P = 0.022). CONCLUSIONS: This analysis from a real-life survey demonstrated that subjects with antipsychotic medication had worse glycemic control and a higher rate of acute complications compared with those without antipsychotic medication. Health care teams caring for youth with type 1 diabetes taking antipsychotic medication need to know about these findings. We suggest monitoring metabolic risk factors as well as providing diabetes education about prevention of acute complications.

OBJECTIVE: To analyze the prevalence of juvenile idiopathic arthritis (JIA) and diabetes end points in pediatric patients with type 1 diabetes. STUDY DESIGN: Patients with type 1 diabetes, recorded from 1995 up to September 2013 in the Diabetes Patienten Verlaufsdokumentation database (n = 54,911, <16 years of age, 47% girls), were analyzed. The patients' height, weight, and body mass index SDS, glycosylated hemoglobin A1c (HbA1c); insulin dose; hypertension and dyslipidemia prevalence; rate of hypoglycemic events; and ketoacidosis were compared between patients with and without JIA. To adjust for age, sex, diabetes duration, and migration background, data were analyzed in hierarchic multivariable regression models. RESULTS: The prevalence of JIA in type 1 diabetes was 106 of 54,911 patients; 66% were girls. Diabetes onset was earlier in children with JIA (7.2 years vs 8.3 years, P = .04). Children with JIA were smaller (SDS: -0.22 vs 0.09, P = .004). Correspondingly, weight SDS was lower in patients with JIA (-0.02 vs 0.22, P = .01). Body mass index SDS did not differ. HbA1c was marginally lower in children with JIA (63 mmol/mol [8.0%] vs 67 mmol/mol [8.3%], P = .06). Insulin requirement was greater in patients with JIA (1.03 vs 0.93 insulin units/weight/day, P = .003). Hypertension and dyslipidemia were comparable in both groups. CONCLUSIONS: The JIA-prevalence in patients with type 1 diabetes (0.19%) was considerably greater than in the general population (0.05%). Growth is influenced negatively by JIA. Surprisingly, HbA1c was somewhat lower in children with JIA, possibly because of a more intensive treatment or a latent hemolysis caused by the inflammation.

OBJECTIVE: To compare clinical characteristics and outcome of type 1 diabetes mellitus (T1DM) between patients with and without a clinically recognized eating disorder (ED). RESEARCH DESIGN AND METHODS: A total of 52,215 T1DM patients aged 8 to <30 years from the prospective diabetes data acquisition system DPV were analyzed. A total of 467 patients had an additional diagnosis of ED according to DSM-IV criteria (anorexia nervosa [AN], n = 141 [female: 94.3%]; bulimia nervosa [BN], n = 62 [90.3%]; and EDs not otherwise specified, including binge-eating disorder [EDNOS], n = 264 [74.2%]). Groups were compared using multivariable regression. Cox proportional hazard ratios were calculated for the association between ED and retinopathy. RESULTS: After adjustment for age, sex, and duration of diabetes, patients with ED revealed higher HbA1c (no ED vs. AN, BN, or EDNOS, respectively: 8.29 ± 0.01% [67.1 ± 0.1 mmol/mol] vs. 8.61 ± 0.15% [70.6 ± 1.6 mmol/mol], 9.11 ± 0.23% [76.1 ± 2.5 mmol/mol], or 9.00 ± 0.11% [74.9 ± 1.2 mmol/mol]) and a higher rate of pathological insulin injection sites (48.4 vs. 64.3, 64.1, or 62.1%). Furthermore, ketoacidosis (5.7 ± 0.1 vs. 12.1 ± 2.1, 18.0 ± 4.1, or 12.9 ± 1.6 events per 100 person-years) and hospitalization (54.9 ± 0.3 vs. 89.3 ± 6.0, 132.0 ± 12.7, or 91.0 ± 4.4 per 100 person-years) were more common, and duration of hospital stay was longer (4.81 ± 0.01 vs. 11.31 ± 0.21, 18.05 ± 0.48, or 8.44 ± 0.13 days per year). All P values were <0.05. Patients with BN and EDNOS had a 2.5-fold (95% CI 1.3-4.8) and a 1.4-fold (0.8-2.3) higher risk for retinopathy, whereas AN patients had no increased risk (0.9 [95% CI 0.4-2.3]). CONCLUSIONS: Diabetes health care professionals should be aware of comorbid EDs in pediatric/young-adult T1DM patients. An ED diagnosis is associated with worse metabolic control and higher rates of diabetes 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 identify risk factors for the development and progression of untreated persistent microalbuminuria in children and adolescents with type 1 diabetes. DESIGN AND METHODS: A total number of 683 children and adolescents with type 1 diabetes recruited from the prospective nationwide German and Austrian diabetes survey (DPV) were included in the analysis. Inclusion criteria were onset of type 1 diabetes under the age of 11 years, diabetes duration of more than 1 year and continuous follow-up over 5 years with at least two documented urine analyses per year. Subjects treated with angiotensin-converting enzyme inhibitors were excluded. Risk factors such as sex, body mass index SDS, diabetes duration, HbA1c, total cholesterol, HDL-cholesterol, LDL-cholesterol, systolic and diastolic blood pressure, and immigrant status were analysed by logistic regression. RESULTS: At baseline (age 10.5 ± 0.1 years, diabetes duration 4.6 ± 2.4 years and HbA1c 7.4 ± 1.1%), 75.6% of children had normoalbuminuria, 15.7% had intermittent microalbuminuria, 8.6% had persistent microalbuminuria and 0.1% had macroalbuminuria. After a follow-up of 5 years, 59.4% of adolescents continued to have normoalbuminuria, 18.4% had progression, 15.2% had regression of microalbuminuria, and in 6.9% of the subjects, microalbuminuria remained unchanged. We found significant associations between persistent microalbuminuria at baseline and during each year of follow-up (P < 0.0001). Logistic regression analysis identified diabetes duration and immigrant status as significant factors for microalbuminuria (P = 0.009 and P = 0.009). CONCLUSIONS: The survey in a real-world setting shows that diabetes duration and immigrant status are risk factors for the development and progression of untreated microalbuminuria in children and adolescents with type 1 diabetes.

BACKGROUND: Severe hypoglycemic episodes are a barrier for achieving optimal glycemic control. Sensor-augmented pump (SAP) therapy with insulin in combination with a novel mechanism of automatic insulin shutoff (low glucose suspend [LGS]) can be used to prevent and reduce hypoglycemia. In a prospective study, we investigated the effect of the LGS algorithm on the frequency of hypoglycemia in children and adolescents with type 1 diabetes under real-life conditions. METHODS: Twenty-one patients with type 1 diabetes (10.8±3.8 years old, duration of diabetes 5.9±3.0 years, pump therapy for 3.7±1.7 years, glycated hemoglobin level 7.8±1.1%) from three pediatric centers used the Paradigm(®) Veo(™) system (Medtronic Minimed, Northridge, CA) during two subseqent time periods: SAP without LGS for 2 weeks and then SAP with LGS enabled for 6 weeks. The primary objective was to assess the frequency of hypoglycemic episodes when using the LGS feature with an insulin delivery shutoff of a maximum of 2 h at a sensor glucose level below 70 mg/dL (3.9 mmol/L). RESULTS: In total, 1,298 LGS alerts occurred (853 shorter than 5 min). Forty-two percent of LGS activations (>5 min) lasted less than 30 min, whereas 24% had a duration of 2 h. The number of hypoglycemic excursions (average/day) was reduced during SAP+LGS (<70 mg/L, 1.27±0.75 vs. 0.95±0.49, P=0.010; ≤40 mg/dL, 0.28±0.18 vs. 0.13±0.14, P=0.005) as was the time spent in hypoglycemia (average minutes/day, 101±68 vs. 58±33, P=0.002) without significant difference in the mean glucose level (145±23 vs. 148±19 mg/dL). No episodes of severe hyperglycemia or diabetic ketoacidosis were observed following LGS activation. CONCLUSIONS: The present investigation provides evidence that SAP with LGS reduces the frequency of hypoglycemia without compromising safety.

Continuous subcutaneous insulin infusion (CSII) is frequently used in children and adolescents. This review discusses pump treatment, as analyzed by the German Working Group for Insulin Pump Treatment in Pediatric Patients. This group has published several papers, in collaboration with the DPV-Wiss (Diabetes-Patienten-Verlaufsdaten) group. The review includes practical aspects of pump treatment and recent results of CSII in Germany, and compares these with American pump treatment.

BACKGROUND: Complementary and alternative medicine (CAM) is increasingly used in adults and children. Studies on CAM in diabetes have mainly focused on the adult population and its use among children with type 1 diabetes has not been well characterized. OBJECTIVES: This study determines prevalence, parental reasons and motivations, perceived effectiveness, costs, and communication of CAM use. Moreover, caregiver-related variables associated with the use of CAM were investigated. METHODS: A self-completed anonymous questionnaire was administered to parents of children with type 1 diabetes in four pediatric diabetes centers in Germany (Leipzig, Berlin, Stuttgart, and Bonn). RESULTS: Two hundred and twenty eight (65.9%) of 346 families completed the survey. Mean age of the diabetic patients was 11.9 +/- 3.8 yr. Forty two (18.4%) received one or more types of CAM, with the most common types being homeopathy (14.5%), vitamins and minerals (13.7%), modified diet (12.9%), aloe vera (7.3%), and cinnamon (5.6%). Users had a significantly higher family income and parental tertiary education (p < 0.05) and stated a significantly stronger interest in self-care (p < 0.01). Parents' motivations for using CAM were the hope for an improved well-being (92.1%), to try everything (77.8%), and assumption of fewer side effects (55.2%). Costs for the entire treatment varied between less than euro100 and up to euro5000, with mostly no reimbursement. CONCLUSIONS: Use of CAM in children with type 1 diabetes is less common than that documented for adults. Parents using CAM do not question the need for insulin. When using CAM, improved well-being and quality of life are important considerations where CAM can have a role.
