Growing up with type 1 diabetes mellitus: Data from the Verona Diabetes Transition Project.

AIM: Transition from paediatric to adult care is a critical step in life of emerging adults with type 1 diabetes. We assessed, according to indicators established by panel of experts, clinical, socio-demographic and psychosocial factors in young adults with type 1 diabetes throughout structured transition to investigate the associations, if any, with HbA1c value at time of transition. METHODS: The "Verona Diabetes Transition Project" started in January 2009: a structured transition program, shared between paediatric and adult clinic, was organised with a multi-disciplinary team. All young adults underwent a semi-structured interview by a psychologist, before transition. Minimum age for transition was 18 years. RESULTS: 222 (M/F = 113/109) young adults moved to adult care from January 2009 to March 2020. The mean time between the last paediatric visit and the first adult visit ranged from 13.6 ± 6.1 months at the beginning of the project to 3.6 ± 11.5 months over the following years. At first adult clinic attendance, women showed higher HbA1c values (70 ± 11 mmol/mol vs. 65 ± 7 mmol/mol or 8.57% ± 1.51% vs. 8.14% ± 0.98%, p = 0.01), higher frequency of disorders of eating behaviours (15.6% vs. 0%, p < 0.001) and poor diabetes acceptance (23.9% vs. 9.7%, p < 0.001) than men. Mediation analyses showed a significant mediating role of glucose control 2 years before transition in the relationship between poor diabetes acceptance and glucose control at transition. CONCLUSIONS: This study demonstrated a delay reduction in establishing care with an adult provider and suggested the potential role of low diabetes acceptance on glycemic control at transition. Further studies are needed to confirm and expand these data.

The role of socio-economic and clinical factors on HbA1c in children and adolescents with type 1 diabetes: an Italian multicentre survey.

OBJECTIVE: To identify the role of the family's socio-economic and clinical characteristics on metabolic control in children and adolescents with type 1 diabetes. METHODS: In this cross-sectional, multicentre study, 768 subjects with type 1 diabetes under 18 years of age were consecutively recruited from January 2008 to February 2009. Target condition was considered for HbA1c values <7.5% (<58 mmol/mol). A multiple correspondence analysis (MCA) was performed to analyze the association between the socio-economic and clinical characteristics of the participants. A logistic regression analysis was performed to identify factors associated with the subjects metabolic control. In both analyses, the family's socio-economic status was represented, measured by the Hollingshead Four-Factor Index of Social Status (SES) or by parental years of education. RESULTS: A total of 28.1% of subjects reached target HbA1c values. The MCA identified a strong association between at-target condition and several factors: high levels of SES or high levels of parental education, the use of the carbohydrate counting system, the use of insulin pumps, the use of the insulin delivery system over a short period of time, a normal body mass index. The logistic regression analysis showed that SES and the mother's years of education were significantly associated with the target condition [odds ratio (OR): 1.01, 95% confidence interval (CI): 1.01-1.03, p = 0.029; OR: 1.05, 95% CI: 1.01-1.10, p = 0.027, respectively). CONCLUSIONS: Personal, clinical, and family characteristics were found to be associated with HbA1c target. Their identification can be crucial in addressing strategies to optimize metabolic control and improve diabetes management.

A rare case of granuloma annulare in a 5-year-old child with type 1 diabetes and autoimmune thyroiditis.

Granuloma annulare (GA) has rarely been reported in childhood, and its etiology still remains unclear. Its association with type 1 diabetes (T1D) and other chronic systemic diseases such as autoimmune thyroiditis (AT) or rheumatoid arthritis has been reported. There is no description in the literature of pediatric cases and the simultaneous association of GA and multiple autoimmune diseases in the same subject. We report the case of a 5-year-old girl who presented onset signs and symptoms of T1D. The diagnosis of T1D was confirmed by the presence of autoimmune T1D antibodies. Moreover, AT was also diagnosed by autoantibodies and positive ultrasound. One month later, coin-size erythematous lesions appeared initially on the trunk but soon spread over the body. Once dermatophytosis had been excluded, a skin biopsy confirmed a diagnosis of GA. Although a clear mechanism remains still unknown, clinicians must take into consideration an association of GA in patients with T1D or AT to avoid unnecessary medical investigations and/or inadequate pharmacological treatment.

Diet, physical, and biochemical characteristics of children and adolescents with type 1 diabetes: relationship between dietary fat and glucose control.

BACKGROUND: Nutritional habits may significantly influence glycemic control and cardiovascular risk factors in youth with type 1 diabetes (T1D). AIMS: To assess dietary intake, cardiovascular risk factors, and the association between diet composition and glycemic control in Italian youth with T1D. METHODS: Subjects included 114 youth aged 6-16 yr with T1D receiving a routine treatment program with nutrition counseling and 448 controls. Cross-sectional measures included dietary intake, anthropometry, blood pressure, lipid profile, and, in children with diabetes, HbA1c. RESULTS: In prepubertal children, BMI, subcutaneous skinfolds, the prevalence of overweight/obesity, and LDL cholesterol (LDL-CH) were significantly lower in patients than in controls, whereas HDL cholesterol (HDL-CH) was higher. Pubertal boys with T1D did not differ significantly from controls in either anthropometry or lipid profile. Pubertal girls with T1D had a higher BMI and higher triceps skinfolds than controls but not significantly different prevalence of overweight/obesity or lipid profile. Compared to controls, participants with T1D had a lower intake of lipids and simple carbohydrates, a higher ratio of unsaturated/saturated fats and fibre, and a dietary intake closer to the National Reference Dietary Intakes (RDIs). The odds of having an HbA1c higher than 7.5, adjusted for BMI, lipid, and fibre intake, increases by 53% for every 1% increase of energy intake from saturated fat in the diet and by 30% for every year of duration of diabetes. CONCLUSIONS: Youth with T1D having regular nutritional counseling had a diet closer to RDIs than controls and not different cardiovascular risk factors. High saturated fatty acid intake was associated with poor blood glucose control.

Randomized Summer Camp Crossover Trial in 5- to 9-Year-Old Children: Outpatient Wearable Artificial Pancreas Is Feasible and Safe.

OBJECTIVE: The Pediatric Artificial Pancreas (PedArPan) project tested a children-specific version of the modular model predictive control (MMPC) algorithm in 5- to 9-year-old children during a camp. RESEARCH DESIGN AND METHODS: A total of 30 children, 5- to 9-years old, with type 1 diabetes completed an outpatient, open-label, randomized, crossover trial. Three days with an artificial pancreas (AP) were compared with three days of parent-managed sensor-augmented pump (SAP). RESULTS: Overnight time-in-hypoglycemia was reduced with the AP versus SAP, median (25(th)-75(th) percentiles): 0.0% (0.0-2.2) vs. 2.2% (0.0-12.3) (P = 0.002), without a significant change of time-in-target, mean: 56.0% (SD 22.5) vs. 59.7% (21.2) (P = 0.430), but with increased mean glucose 173 mg/dL (36) vs. 150 mg/dL (39) (P = 0.002). Overall, the AP granted a threefold reduction of time-in-hypoglycemia (P < 0.001) at the cost of decreased time-in-target, 56.8% (13.5) vs. 63.1% (11.0) (P = 0.022) and increased mean glucose 169 mg/dL (23) vs. 147 mg/dL (23) (P < 0.001). CONCLUSIONS: This trial, the first outpatient single-hormone AP trial in a population of this age, shows feasibility and safety of MMPC in young children. Algorithm retuning will be performed to improve efficacy.

Evaluating the Experience of Children With Type 1 Diabetes and Their Parents Taking Part in an Artificial Pancreas Clinical Trial Over Multiple Days in a Diabetes Camp Setting.

OBJECTIVE: To explore the experiences of children with type 1 diabetes and their parents taking part in an artificial pancreas (AP) clinical trial during a 7-day summer camp. RESEARCH DESIGN AND METHODS: A semistructured interview, composed of 14 questions based on the Technology Acceptance Model, was conducted at the end of the clinical trial. Participants also completed the Diabetes Treatment Satisfaction Questionnaire (DTSQ, parent version) and the AP Acceptance Questionnaire. RESULTS: Thirty children, aged 5-9 years, and their parents completed the study. A content analysis of the interviews showed that parents were focused on understanding the mechanisms, risks, and benefits of the new device, whereas the children were focused on the novelty of the new system. The parents' main concerns about adopting the new system seemed related to the quality of glucose control. The mean scores of DTSQ subscales indicated general parents' satisfaction (44.24 ± 5.99, range 32-53) and trustful views of diabetes control provided by the new system (7.8 ± 2.2, range 3-12). The AP Acceptance Questionnaire revealed that most parents considered the AP easy to use (70.5%), intended to use it long term (94.0%), and felt that it was apt to improve glucose control (67.0%). CONCLUSIONS: Participants manifested a positive attitude toward the AP. Further studies are required to explore participants' perceptions early in the AP development to individualize the new treatment as much as possible, and to tailor it to respond to their needs and values.

Epidemiology of type 1 diabetes mellitus in the pediatric population in Veneto Region, Italy.

We assessed the prevalence and incidence of type 1 diabetes mellitus (T1DM) in Veneto Region in Italy. The average prevalence and incidence rates were 1.26/1000 subjects and 16.5/100,000 person-years, respectively. This study shows that the Veneto Region is an area with intermediate-high risk of T1DM.

Nutritional education and carbohydrate counting in children with type 1 diabetes treated with continuous subcutaneous insulin infusion: the effects on dietary habits, body composition and glycometabolic control.

Carbohydrate counting (CHC) in combination with nutritional education has been used to optimize the insulin dose in patients with type 1 diabetes (T1D). The aim of this study was to test the impact of CHC and nutritional education on changes in dietary habits, body composition and body fat distribution in children with T1D treated with insulin pumps (CSII). Twenty-five children with T1D and CSII were recruited and valuated at baseline and after 18 months of follow-up. They were trained in CHC and following standard nutrition education program (based on American Diabetes Association and International Society of Pediatric and Adolescent Diabetes guidelines); clinical, biochemical and nutritional variables were measured. In the total population, body composition, body fat distribution and biochemical variables did not change, at follow-up; HbA1c was significantly reduced (8.50 ± 0.77 vs 7.92 ± 0.74 %; p < 0.001) without changing insulin/kg/day requirement. In the sub-group of patients with a significant HbA1c reduction (ΔHbA1c ≥ 0.5 %, n = 12), the carbohydrate (CHO) intake was significantly higher at follow-up (53.0 ± 4.0 vs 57.6 ± 2.5 %; p < 0.01); on the contrary, fat (31.3 ± 3.6 vs 28.5 ± 1.6 %; p < 0.05) and protein intake (15.4 ± 1.8 vs 13.3 ± 1.6 %; p < 0.01) significantly decreased. Patients without a significant HbA1c reduction did not show any difference. CHC, in combination with nutritional education, does not affect dietary habits, body composition and body fat distribution in children with T1D treated with CSII. Moreover, the sub-group of subjects showing a significant improvement in glycometabolic control reported an increase in CHO intake and a reduction in fat and protein intake.
