Non-suicidal self-injury in adolescents and young adults with type 1 diabetes: clinical characteristics from a German diabetes-patient registry (DPV).

The aim was to examine the relations between non-suicidal self-injury (NSSI) and clinical parameters as well as other psychiatric comorbidities in adolescents and young adults with type 1 diabetes mellitus (T1D). Patients aged 8-<=25 years with T1D and documented NSSI from the DPV database (n=167) were compared to a control group with T1D without NSSI or other psychiatric comorbidities (n=76,050) using multivariable regression models, adjusted for demographics. Clinical diabetes-related outcomes (haemoglobin A1c (HbA1c), daily insulin dose, diabetic ketoacidosis (DKA), hypoglycaemia, number of hospital days, number of hospital admissions) were analysed. NSSI patients had significantly higher HbA1c (%): (+1.1 [0.8; 1.4]), higher daily insulin doses: (+0.08 (U/kg), [0.02; 0.13]), more DKA events per patient year: (+1.79 [1.22; 2.37]), more hospital days per patient year: (+0.25 [0.20; 0.29]) and more frequent hospital admissions per patient year: (+0.93 [0.79; 1.06]) compared to T1D patients without NSSI or other psychiatric comorbidities (differences of adjusted estimates [confidence interval]). This is the first study to investigate the association between NSSI and T1D. We revealed that NSSI is significantly related to diabetes outcomes in adolescent T1D patients. There should be an increased awareness for NSSI in the care for adolescents and young adults with T1D.

Hyperthyroidism in 276 Children and Adolescents with Type 1 Diabetes from Germany and Austria.

BACKGROUND/AIMS: Little is known about the incidence and clinical consequences of hyperthyroidism in pediatric patients with type 1 diabetes mellitus (T1DM). METHODS: We analyzed the DPV database (Diabetes Prospective Follow-Up Registry) to investigate the rate of hyperthyroidism in pediatric T1DM patients, its impact on metabolic control, and potential associations with organ-specific autoantibodies. RESULTS: Hyperthyroidism was found in 276/60,456 patients (0.46%) and was associated with younger age, shorter diabetes duration, female sex, and reduced body mass index. Diabetic ketoacidosis (DKA) and hypoglycemia were more frequent in T1DM with comorbid hyperthyroidism, while long-term metabolic control (HbA1c) was similar in both groups. Absolute blood pressure and arterial hypertension rate were elevated in the hyperthyroid patients. Rates of microalbuminuria and diabetic retinopathy were not different. Thyroid-specific antibodies (thyroid peroxidase, thyroglobulin, thyroid receptor) were associated with hyperthyroidism. Thyroid volume and rates of cysts and nodules were higher, and echogenicity was decreased. CONCLUSION: Prevalence of hyperthyroidism is low in diabetic children with T1DM but increased compared to children <18 years without diabetes. Hyperthyroidism is primarily associated with acute diabetes complications (DKA and hypoglycemia) and affects blood pressure regulation. Long-term metabolic control or insulin requirement were not different.

Hospital admission for diabetic ketoacidosis or severe hypoglycemia in 31,330 young patients with type 1 diabetes.

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.
