本研究为英国13家NHS儿科糖尿病中心参与的多中心回顾性队列研究,纳入220名年龄≤19岁、病程>1年、起始时HbA1c≥69 mmol/mol的1型糖尿病儿童及青少年。结果显示,启动混合闭环胰岛素泵治疗后,HbA1c显著下降,且在高基线HbA1c(>100 mmol/mol)及从每日多次注射转换的患者中改善更明显,糖尿病相关住院率也总体降低。

要点

  • 混合闭环胰岛素泵可显著降低高HbA1c患儿的糖化血红蛋白。
  • 基线HbA1c>100 mmol/mol者降幅更大。
  • 糖尿病相关住院次数总体减少。

核心结论

  • 在HbA1c偏高的儿童及年轻人中,启动混合闭环疗法与血糖控制的持续改善及更少的糖尿病相关住院相关,支持在这一高危人群中使用该疗法。

研究设计与样本

  • 多中心回顾性观察性队列研究,共纳入220名参与者。
  • 研究在英国英格兰一个区域糖尿病网络内的13个国家卫生服务儿科糖尿病中心开展。
  • 纳入标准:年龄≤19岁,1型糖尿病病程超过1年,启动HCL时及至少3个月前HbA1c≥69 mmol/mol。

主要发现

  • 启动HCL后HbA1c显著下降。
  • 基线HbA1c较高(>100 mmol/mol)者和从每日多次注射转换者改善更显著。
  • 不同HCL泵系统间的结果相似。
  • 启动HCL后,糖尿病相关住院总体减少。

关键数值与推荐

  • 纳入标准:年龄≤19岁,HbA1c≥69 mmol/mol(启动时及之前至少3个月)。
  • 主要结局指标:启动HCL后HbA1c的变化。

临床怎么用

  • 支持在HbA1c偏高(≥69 mmol/mol)的儿童及青少年中优先考虑使用混合闭环胰岛素泵治疗。
  • 尤其对于基线HbA1c>100 mmol/mol或原用每日多次注射的患者,获益可能更明显。
  • 不同HCL系统间疗效相似,可根据临床情况选择。

局限性

  • 本研究为观察性研究,可能存在混杂因素和选择偏倚。
  • 未报告具体的随访时长和住院率的具体数值。
  • 未提供不同亚组的详细分层数据和泵系统比较的详细统计结果。

Objective To evaluate changes in glycated haemoglobin (HbA1c) following initiation of hybrid closed-loop (HCL) insulin pump therapy in children and young people (CYP) with previously elevated HbA1c in a real-world multicentre setting. Design Retrospective multicentre observational cohort study. Setting 13 National Health Service paediatric diabetes units within a regional diabetes network in England, UK. Patients CYP aged ≤19 years with type 1 diabetes of more than 1 year’s duration and HbA1c ≥69 mmol/mol at the time of HCL initiation and at least 3 months prior. Interventions Initiation of HCL insulin pump therapy. Main outcome measures Primary outcome was change in HbA1c following HCL initiation. Secondary outcomes included subgroup and pump system comparisons and changes in diabetes-related hospital admissions. Results A total of 220 participants were included. HbA1c decreased significantly following HCL initiation (p100 mmol/mol) and in participants transitioning from multiple daily injections. Outcomes were similar across HCL pump systems, and diabetes-related hospital admissions decreased overall following HCL initiation. Conclusions In this large, real-world cohort of CYP with high HbA1c, initiation of HCL therapy was associated with sustained improvements in glycaemic control and fewer diabetes-related hospital admissions, supporting its use in this high-risk population.
