Commercial hybrid closed-loop systems available for a patient with type 1 diabetes in 2022.

Abstract

Technological advances offer the opportunity to improve glycemic control and reduce the risk of complications and burden of type 1 diabetes while improving patient quality of life. Closed-loop insulin delivery systems take the technology to alarger scale by integrating CGM systems with an insulin pump and an algorithm that automates insulin delivery (HCL systems). Several systems using hybrid closed loop technology are currently offered in the global marketplace: the MiniMed™ 670G and MiniMed™ 780G (SmartGuard™) system from Medtronic; the T slim x2 Control IQ from Tandem; the Omnipod5 automated mode (HypoProtect™)5 from Insulet; and the CamAPS FX DanaRS or Ypso pump. Insulet's Omnipod5 automated mode (HypoProtect™) is currently in clinical trials. As technology moves forward, advanced systems are being developed that include an elaborate algorithm with individualization of major target points, automated correction bolus functionality, and increased stability of the automated mode (Advanced Hybrid Closed-Loop - AHCL systems). The AHCL systems include: MiniMed™ 780G (SmartGuard™); Tandem's T slim x2 Control IQ; Insulet's Omnipod5-Automated mode (HypoProtect™); and CamAPS FX. The purpose of this paper is to present commercial devices using HCL and AHCL in 2022, also from ascientific point of view. It is an undeniable fact that "auto-mode" systems represent anew stage that can be confidently called arevolution in diabetology.
