Evolution of the Artificial Pancreas: Components and Integration-CGMs, Insulin, and AP Systems

Area of Science:

• Endocrinology and Metabolic Diseases
• Biomedical Engineering
• Diabetes Technology

Background:

• The Diabetes Control and Complications Trial (DCCT) established glucose control as crucial for preventing diabetes complications.
• Subsequent research focused on improving glycemic management while minimizing hypoglycemia.

Purpose of the Study:

• To review innovations in diabetes technology following the DCCT.
• To explore advancements in continuous glucose monitoring (CGM) and automated insulin delivery (AID) systems.
• To discuss future directions for fully autonomous diabetes management systems.

Main Methods:

• Review of innovations in wired enzyme technology leading to factory-calibrated CGM.
• Analysis of automated insulin delivery (AID) systems, including pump types, algorithms, and data management.
• Summary of trials for alternative insulin delivery routes and implantable systems.
• Exploration of integrating additional sensor data (ketones, lactate, insulin) for enhanced feedback.

Main Results:

• Development of continuous glucose monitoring (CGM) systems, including the first factory-calibrated version.
• Introduction and approval of automated insulin delivery (AID) systems in the United States.
• Ongoing research into implantable insulin delivery systems and multi-analyte sensing.

Conclusions:

• Technological advancements have significantly improved glucose control and reduced hypoglycemia in diabetes management.
• Automated insulin delivery (AID) systems represent a major step towards more autonomous diabetes care.
• Future research focusing on integrated sensor data and alternative delivery routes holds promise for fully autonomous systems.
