简要总结

Hybrid Closed Loop (HCL) systems, such as the MiniMed 780G, have significantly improved glycemic outcomes in Type 1 Diabetes (T1D) management. The MiniMed 780G, an Advanced Hybrid Closed Loop (AHCL) system, features autocorrection boluses and unique insulin adjustment technologies. While effective, the system requires user input for meal announcements. Some individuals attempt to "trick" the system by entering "fake carbs" to prompt additional insulin corrections. However, clinical evidence suggests this practice does not improve glycemic outcomes.

This study, conducted in Athens, Greece, will involve 40 children and adolescents (ages 7-18) with Type 1 Diabetes who have been using the MiniMed 780G system for over 6 months. The open-label, crossover design explores the impact of 'fake carbohydrates' on glycemic control. Participants will be split into two groups: one starts with 'fake carbohydrates' and then stops, while the other does the reverse. Over two weeks, their glycemic outcomes will be monitored and compared, with exclusions for severe diabetes complications or serious diabetic events

This study hypothesizes that using "fake carbs" does not enhance glycemic control. Findings are expected to provide evidence-based insights to optimize diabetes management and improve clinical guidance for HCL system users.

详细描述

Aim of the Study To compare glycemic control outcomes in individuals with T1D using the MiniMed™ 780G system during periods when 'fake carbohydrates' are used versus periods when this strategy is not employed.

Definition: Fake Carbohydrates As a Fake Carbs practice is defined the practice when the user enters fake quantity of carbohydrates in order to trigger the system to suggest and deliver a bolus insulin with the aim to correct hyperglycemia.

Study Design and Participants This is a prospective, open-label, randomized, crossover trial conducted at the Diabetes Center of the General Hospital "P. & A. Kyriakou" in Athens, Greece.

Sample Size

  • Total Participants: 40 children and adolescents
  • Age Range: 7-18 years Inclusion Criteria
  • Diagnosis of T1D
  • Using the MiniMed™ 780G system for ≥6 months
  • Habitual use of fake carbohydrates in daily management Exclusion Criteria
  • Severe diabetes-related complications
