概括
在1型糖尿病 (T1D) 的自动胰岛素输送 (AID) 中,玻尿酸原始化系统 (BPS) 显示了食后葡萄糖升高的减少. 这项创新旨在实现一个"完全闭环" (FCL) 系统,减少餐时间干预.
科学领域:
- 内分泌学 在内分泌学.
- 生物医学工程 生物医学工程
- 代谢疾病 代谢疾病
背景情况:
- 自动化胰岛素输送系统 (AID) 在1型糖尿病 (T1D) 中显著改善血糖控制.
- 下一代AID系统旨在实现一个
- 完全封闭的循环循环.
- (FCL) 的方法是尽量减少用户互动,特别是在餐点周围.
- 玻尿酸原始化系统 (BPS) 是一种算法,旨在根据食概率预测提供固定的胰岛素剂量.
研究的目的:
- 评估与先进的AID系统集成的玻尿酸原始化系统 (BPS) 的食后血糖影响.
- 在随机交叉试验中,在现实环境中评估BPS的安全性和有效性.
主要方法:
- 一个随机交叉试验涉及11名T1D成年人进行了两个24小时的会议.
- 参与者体验到相同的饮食和活动水平,一个会议使用BPS,另一个没有.
- 分析了持续血糖监测 (CGM) 数据和胰岛素剂量,重点关注食后血糖游览和时间范围 (TIR).
主要成果:
- 总体而言,白天CGM指标,包括TIR和时间低于范围,在BPS和非BPS条件之间是相似的.
- 与没有BPS条件相比,BPS激活后的食用后增量曲线下面面积 (iAUC) 显著较低 (P=0.047).
- 尽管IAUC较低,但饭后4小时的TIR并没有显示这两种情况之间的统计学上显著差异 (P=0.24).
结论:
- 玻尿酸启动系统 (BPS) 通过提前提供胰岛素,显示出在完全闭环 (FCL) AID系统中改善食后血糖控制的潜力.
- 虽然整体TIR没有显著的差异,但食后葡萄糖外游的减少表明BPS是未来AID进步的一个有希望的组成部分.
- 没有报告任何严重的不良事件,这表明BPS算法在T1D群体中具有良好的安全性.

Oral Hypoglycemic Agents: Glinides
141
Repaglinide (Prandin) and Nateglinide (Starlix), known as glinides, are oral insulin secretagogues that stimulate insulin release from pancreatic β cells by closing the ATP-sensitive potassium channels (KATP channel). Repaglinide controls insulin release from pancreatic β cells by managing potassium efflux. It shares two binding sites with sulfonylureas and also has a unique site, indicating overlapping mechanisms of action. With a rapid onset and a 4-7 hour duration, it effectively...

Glucagon-like Receptor Agonists
300
Incretins include glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP), which stimulate insulin secretion post-meals. In type 2 diabetes, GIP's efficacy is reduced, making GLP-1 a viable drug target. GIP originates from preproGIP.
GLP-1, when administered in high doses intravenously, triggers insulin secretion, inhibits glucagon release, slows gastric emptying, reduces food intake, and restores normal insulin secretion. However, its rapid inactivation by...

Insulin: Dosing Regimen and Adverse Effects
146
Insulin-replacement therapy usually includes both long-acting insulin (basal) and short-acting insulin (to cater to postprandial needs). In a diverse group of type 1 diabetes patients, the average daily insulin dose is typically 0.5-0.7 units/kg body weight. However, obese patients and pubertal adolescents may need more due to insulin resistance.
The basal dose constitutes about 40%-50% of the total daily dose, with the rest as premeal insulin. The mealtime insulin dose should mirror...

Insulin Formulations: Types and Delivery
169
Insulin preparations are categorized by their duration of action into short-acting and long-acting types. Two strategies are used to modify insulin's absorption and pharmacokinetic profile: slowing the absorption post-subcutaneous injection, or altering human insulin's amino acid sequence or protein structure. These changes retain the insulin's ability to bind to the insulin receptor, but alter its behavior in solution or after injection.
Short-acting insulins are divided into...

Hypoglycemia and Glucagon
152
Without prolonged fasting, healthy individuals maintain blood glucose levels above 3.5 mM due to a well-adapted neuroendocrine counterregulatory system that effectively prevents acute hypoglycemia, a potentially life-threatening condition. The primary clinical scenarios for hypoglycemia encompass diabetes treatment, inappropriate production of endogenous insulin or insulin-like substances by tumors, and the use of glucose-lowering agents in non-diabetic individuals. Notably, hypoglycemia in the...

One-Compartment Open Model for IV Bolus Administration: General Considerations
164
The one-compartment model is a pharmacokinetic tool that models the body as a single, uniform compartment, facilitating the understanding of drug distribution and elimination. This model is particularly beneficial for intravenous (IV) bolus administration, where the drug rapidly circulates throughout the body.
The drug's presence in the body is defined by an equation representing the difference between the rates of drug entry and exit. Key parameters—elimination rate constant,...
