Summary

In this observaltional study, 240 patients aged \>12 years old with T1DM who are on multiple daily injections or insulin pump and are scheduled to start using MiniMed 780G system will be included.We aim to compare patients' adherence to Mediterranean diet (MD) before and 12 weeks after initiation of MiniMed 780G and its association with CGM and insulin metrics, as well as anthropometric measurements, BMI, body composition, lipid levels, blood pressure and gut microbioma. Moreover, at baseline, at six and 12 months, markers of endothelial and cardiovascular function will be also assessed and associated with the use of Minimed 780G and the adherence to MD.

Detailed description

This observational study will include 240 participants (80 participants per country) from IGI region (Italy, Greece and Israel), children adolescents and young adults (12\> years old) with T1D that are on multiple daily injections or insulin pump and are scheduled to start using MiniMed 780G system. After a 7-day run-in period, participants will be evaluated with food intake log and adherence to Meditteranean Diet (MD) with PREDIMED questionnaire. One hour session on MD and healthy impact on Diabetes will be provided to all participants and will be assigned to initiate MiniMed 780G and followed for 12 weeks. HbA1c, CGM and Insulin Metrics, anthropometric measurements, body composition, blood pressure and lipid leves as well a gut microbioma will be performed at baseline and 12 weeks, after MiniMed 780G initiation. A 7-day food diary logbook will be collected to identify the amount and type of the food at baseline and at the end of the study. At baseline, at 6 and at 12 months, markers of endothelial and cardiovascular function will also be assessed. An extension phase will include additional 3 and 6, which concludes one year of follow-up.

Interventions

Type	Name	Description
DEVICE	MInimed 780G	Minimed 780G HCL system (Metronic, Northridge, Ca, USA) is ConformitèEuropëenne(CE)-marked and includes additional functionality aiming to provide further protections from high glucose levels. When the system is used in Auto Mode automatically calculate the insulin dose based on information received from CGM. Signals are converted by the transmitter to sensor glucose values. Sensor values are then transmitted to the insulin pump. Sensor glucose and insulin delivery data are stored by the pump and may be uploaded. The HCL system can be programmed to automatically calculate insulin doses (both basal insulin and correction boluses) based on information received from CGM780G and the adherence to MD.
