Abstract

Background and aims

Maintaining glucose levels in the target range during aerobic training and athletic competition is especially difficult. The use of Automated Insulin Delivery (AID) technology is increasing, but exercise continues to be a challenge for persons with type 1 diabetes (T1D). In this case report series, we present 3 cases (C1, C2 and C3) of persons with T1D who used the MiniMed 780G during marathon races. We describe the strategies they used before, during and after the race to manage their glycaemia as well as the results of these strategies on their glycaemic control during the race.

Methods

The Medtronic CareLink platform was employed to remotely access insulin pump settings and glycaemic outcomes. Race parameters were obtained from sport watches. Supplemental data were obtained through interviews.

Results

Carelink data for Cases 1, 2, and 3 before the race were downloaded: Time in range (TIR) 70–180 mg/dL 89%, 76%, 82%; time above range (TAR) > 180 mg/dL, 9%, 20%, 16%; time below range (TBR) < 70 mg/dL, 1%, 4%, 1%, respectively. The breakfast insulin reduction percentages were −25%, 0%, and 0% for C1, C2, and C3, respectively. In all three cases, insulin dose reduction was applied to the pre-race snack at percentages of −50%, −100% and −83%. The consumption of carbohydrates during the race was 0.39 g/kg/hour, 0.42 g/kg/hour, and 0.5 g/kg/hour, respectively. The total amount of carbohydrates consumed was 101 g, 120 g, and 115 g, respectively. Throughout the race, a temporary target was used for all cases.

Conclusions

These cases provide insights for healthcare professionals who assist athletes with T1D using AID systems during prolonged physical activities. Highlighting the significance of specialised education, planning, and personalised approaches.

在马拉松比赛中使用先进的混合闭环系统:案例和临床意义
背景和目的在有氧训练和运动比赛中,将血糖水平维持在目标范围内是非常困难的。自动化胰岛素输送(AID)技术的使用正在增加,但运动仍然是1型糖尿病患者(T1D)的一个挑战。在本病例报告系列中,我们报告了3例(C1, C2和C3) T1D患者在马拉松比赛中使用MiniMed 780G的病例。我们描述了他们在比赛前、比赛中和比赛后使用的血糖控制策略,以及这些策略在比赛期间对血糖控制的效果。方法采用美敦力CareLink平台远程访问胰岛素泵设置和血糖结局。从运动手表中获得了比赛参数。通过访谈获得补充数据。结果:病例1、病例2和病例3在比赛前的Carelink数据下载:TIR范围(Time in range, TIR) 70 ~ 180 mg/dL 89%、76%、82%;超过范围时间(TAR) >;180 mg/dL, 9%, 20%, 16%;低于范围时间(TBR) <;70 mg/dL, 1%, 4%, 1%。C1、C2和C3的早餐胰岛素降低率分别为- 25%、0%和0%。在所有三种情况下,赛前零食的胰岛素剂量分别为- 50%,- 100%和- 83%。比赛期间碳水化合物的消耗量分别为0.39 g/kg/小时、0.42 g/kg/小时和0.5 g/kg/小时。摄入的碳水化合物总量分别为101克、120克和115克。在整个比赛过程中,所有情况都使用了一个临时目标。结论:这些病例为帮助T1D运动员在长时间体育活动中使用AID系统的医疗保健专业人员提供了见解。强调专业教育、规划和个性化方法的重要性。
