Abstract
Background: Advanced hybrid closed loop (AHCL) systems are the newest tool to improve metabolic control in type 1 diabetes (T1D). Long-term glycemic control of children and adolescents with T1D switching to MiniMed™ 780G in a real clinical setting was evaluated.
Methods: Time in range (TIR) and in different glucose ranges, glycemic variability indexes, HbA1c and basal-bolus insulin distribution were evaluated in 44 subjects (mean age 14.2 ± 4.0 years, 22 males) during manual mode period, first 14 days (A14d) and first month after auto-mode activation (A1M), first 14 days after 3 months (A3M) and 6 months (A6M) in auto-mode.
Results: Mean TIR at A14d was 76.3 ± 9.6% versus 69.3 ± 12.6% in manual mode (p < 0.001), and this improvement was maintained over 6 months. Subjects with TIR >70% and >80% in manual mode were 45% and 23%, respectively, and increased to 80% (p = 0.041) and 41% (p = 0.007) at A14d. Basal-bolus distribution changed in favor of bolus, and auto-correction boluses inversely correlated with TIR. HbA1c was 7.2 ± 0.7% (55 mmol/mol) at baseline and significantly improved after 3 months (6.7 ± 0.5%, 50 mmol/mol, p < 0.001) and 6 months (6.6 ± 0.5%, 49 mmol/mol, p < 0.001). TIR was higher in individuals >13 years at all time periods (p < 0.001). Glycemic target <120 mg/dl was associated with better TIR.
Conclusions: AHCL MiniMed™ 780G allowed rapid and sustained improvement of glycemic control in young T1D patients, reaching recommended TIR. Teenagers showed good technology adherence with optimal TIR, maintained better over time compared to younger children. Stricter settings were associated with better metabolic control, without increase in severe hypoglycemia occurrence.
期刊介绍：
Pediatric Diabetes is a bi-monthly journal devoted to disseminating new knowledge relating to the epidemiology, etiology, pathogenesis, management, complications and prevention of diabetes in childhood and adolescence. The aim of the journal is to become the leading vehicle for international dissemination of research and practice relating to diabetes in youth. Papers are considered for publication based on the rigor of scientific approach, novelty, and importance for understanding mechanisms involved in the epidemiology and etiology of this disease, especially its molecular, biochemical and physiological aspects. Work relating to the clinical presentation, course, management and outcome of diabetes, including its physical and emotional sequelae, is considered. In vitro studies using animal or human tissues, whole animal and clinical studies in humans are also considered. The journal reviews full-length papers, preliminary communications with important new information, clinical reports, and reviews of major topics. Invited editorials, commentaries, and perspectives are a regular feature. The editors, based in the USA, Europe, and Australasia, maintain regular communications to assure rapid turnaround time of submitted manuscripts.
