An 8-Day Initiation of Advanced Hybrid Closed Loop System In Children and Adolescents
One of the available Hybrid closed loop system is MiniMed 670G (Medtronic Diabetes, Northridge, CA, USA), which is indicated for children above 7 years old, adolescents and adults with Type 1 Diabetes. Several studies have shown improved HbA1c, time in target range, and SG variability in children, adolescents and adults with Type 1 Diabetes, where participants were experienced with using CSII therapy, assuming that the success of HCL systems depend on prior use of pump therapy. A recent study, published by diabetes team from Sidra Medicine, Doha has showed that children and adolescents with Type 1 Diabetes on MDI therapy can successfully initiate the HCL system, using a concise structured 10-day protocol, achieving better outcomes than in previous studies, where participants had previous experience with diabetes related technology and longer initiation process. The AHCL system, Minimed 780G is CE-marked includes additional functionality aiming to provide further protections from highs. The user can choose the algorithm to target a glucose level of 100 or 120 mg/dL. Like for the MiniMed 670G HCL system, users can also choose the algorithm to temporarily target a glucose value of 150 mg/dL. In addition, the AHCL system has the ability to administer correction bolus automatically, targeting 120 mg/dL. The AHCL algorithm was evaluated with a model-based algorithm design platform incorporating a virtual patient simulator, where additional changes were made (lower target ranges and automated correction boluses ( )). A recent study including 12 patients with type 1 diabetes on AHCL system, has shown no episodes of hypoglycemia or diabetic ketoacidosis, while maintaining 99% time spent in closed loop and high time in ra1]\nge ( ). AHCL decreased Auto Mode exits and alerts, and improves glycaemia without compromising safety, despite multiple food and exercise challenges ( ). Sidra Medicine is the only center for childhood diabetes in Qatar. Around 80% of type 1 diabetes patients are using a device (insulin pump/glucose sensor) and around 45% are using sensor-augmented pump (SAP)/HCL systems.
