RESUMO
BACKGROUND: With increasing obesity in childhood and adolescence, weight gain, and insulin resistance become also more frequent in patients with type 1 diabetes mellitus (T1DM). Especially during puberty, insulin therapy often has to be intensified and higher insulin doses are necessary. Some studies point to a beneficial effect of metformin in addition to insulin in these patients. In order to describe current practice and possible benefits, we compared pediatric T1DM patients with insulin plus metformin (n = 525) to patients with insulin therapy only (n = 57 487) in a prospective multicenter analysis. METHODS: Auxological and treatment data from 58 012 patients aged <21 yr with T1DM in the German/Austrian Diabetes Patienten Verlaufsdokumentation (DPV) registry were analyzed by multivariable mixed regression modeling. RESULTS: Patients with additional metformin were older [median (interquartile range)]: [16.1 (14.1-17.6) vs. 15.2 (11.5-17.5) yr] with female preponderance (61.0 vs. 47.2%, p < 0.01). They had higher body mass index-standard deviation score (BMI-SDS) [+2.03 (+1.29 to +2.56) vs. +0.51 (-0.12 to +1.15); p < 0.01] and glycated hemoglobin (HbA1c) (9.0 vs. 8.6%, p < 0.01). Hypertension (43.7 vs. 24.8%) and dyslipidemia (58.4 vs. 40.6%) were significantly more prevalent. Adjusted insulin dose was significantly higher (0.98 vs. 0.93 IU/kg bodyweight). In a subgroup of 285 patients followed-up longitudinally (average treatment period 1.42 yr), addition of metformin resulted in a slight reduction of BMI-SDS [-0.01 (-2.01 to +1.40)], but did not improve HbA1c or insulin requirement. CONCLUSION: Additional metformin therapy in T1DM is primarily used in obese females. Additional therapy with metformin was associated with minor benefits.

AIMS: To analyse the association between coeliac disease (CD) and depression in children, adolescents, and young adults with type 1 diabetes (T1D). METHODS: We included 79,067 T1D patients aged 6-20 years, with at least six months of diabetes duration, and treatment data between 1995 and 2019 were documented in the diabetes patient follow-up registry. We categorized patients into four groups: T1D only (n = 73,699), T1 + CD (n = 3379), T1D + depression (n = 1877), or T1D + CD + depression (n = 112). RESULTS: CD and depression were significantly associated (adjusted OR: 1.25 [1.03-1.53]). Females were more frequent in both the depression and the CD group compared with the T1D only group. Insulin pumps were used more frequently in T1D + CD and T1D + depression compared with T1D only (both p < .001). HbA1c was higher in T1D + depression (9.0% [8.9-9.0]), T1D + CD + depression (8.9% [8.6-9.2]), both compared with T1D only (8.2% [8.2-8.2], all p < .001). We found comorbid autism, attention deficit hyperactivity disorder, anxiety, schizophrenia, and eating disorders more frequently in the T1D + CD + depression group compared with T1D only (all p < .001). CONCLUSIONS: CD and depression are associated in young T1D patients. The double load of T1D and CD may lead to an increased risk for depression. Depression was associated with additional psychological and neurological comorbidities. Aside from imperative CD screening after T1D diagnosis and regular intervals, depression screening might be helpful in routine care, especially in patients with diagnosed CD.

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.
