Aim of this study is to verify the effects of an advanced HCL (Medtronic Minimedâ„¢ 780G) compared to SAP with PLGS on metabolic outcomes and markers of early microvascular damage in a population of adults with T1D previously treated with CSII. Evaluation of endothelial disfunction and autonomic neuropathy will also be performed.
New algorithms for the automation of insulin delivery (AID) are showing great benefit on glucose control in people with type 1 diabetes. Indeed, Hybrid closed loop (HCL) systems can improve HbA1c levels, percentage of time in defined glucose range, time below range and time over range, according to RCT and observational studies results. However, scientific evidences demonstrating potential benefits on the reduction of diabetes complications are limited regarding CSII or SAP with demonstrated reduction of cardiovascular mortality, improvement of albuminuria and peripheral nerve damage.
Data on AID effects on complications of diabetes are missing. In this study intermediate damage markers will be measured to assess potential effects of AID in comparison to sensor augmented pumps.

| Endothelial disfunction | Endothelial-dependent dilation (EDD) is considered a marker of dysfunctional abnormalities involved in early phases of atherosclerosis development. Changes in EDD precede structural changes and occurs in the preclinical phase of vascular disease. In the present study endothelial dependent dilation is assessed by color Doppler evaluation of flow increase after hyperemia. | From Baseline to 26 weeks |
