概括
晚间低血糖虽然较少,但持续时间较长,对糖尿病患者的第二天血糖控制的影响更大. 需要改进预防策略来控制这些长时间的夜间低血糖水平.
科学领域:
- 内分泌学
- 代谢疾病
- 糖尿病管理
背景情况:
- 夜间低血糖是糖尿病治疗的常见并发症.
- 持续血糖监测 (CGM) 的数据往往低于夜间低血糖,特别是在2型糖尿病 (T2D) 中.
- 与白天低血糖相比,夜间低血糖的持续时间和白天影响的了解有限.
研究的目的:
- 在1型糖尿病 (T1D) 和2型糖尿病患者中,比较夜间低血糖的频率和持续时间.
- 评估夜间低血糖对随后白天血糖的影响.
- 强调需要加强夜间低血糖的预防策略.
主要方法:
- 对3696名T1D患者和441名T2D患者每天多次注射胰岛素的CGM数据进行了回顾性分析.
- 低血糖事件定义为CGM读数<70 mg/dL或<54 mg/dL长达≥15分钟.
- 夜间低血糖与白天低血糖的发生率,持续时间和第二天的血糖影响的比较.
主要成果:
- 与白天发生的事件相比,夜间低血糖发生的频率较低,但平均持续时间较长 (T1D 65分钟,T2D 57分钟).
- 在夜间低血糖后,观察到白天血糖指标的显著变化,这表明早晨低血糖的风险增加.
- 这些发现在T1D和T2D群体中一致.
结论:
- 夜间低血糖症的特征是持续时间较长,恢复速度较慢.
- 夜间低血糖明显影响第二天的血糖控制,增加了早晨低血糖的风险.
- 在糖尿病治疗中,急需改进预防和管理夜间低血糖的策略.

Hypoglycemia and Glucagon
334
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...

Glucose Homeostasis: Regulation of Blood Glucose
2.5K
Carbohydrates consumed through foods are converted into glucose, a crucial energy source for the body. In the prandial state, high blood glucose levels stimulate the secretion of insulin from the pancreas. Insulin inhibits hepatic glucose production and stimulates glucose uptake and metabolism by muscle and adipose tissue. The excess glucose is converted into glycogen and stored in the liver and muscles.
During fasting, when blood glucose levels are low, the pancreas secretes glucagon. it...

Hormones Regulating Blood Glucose
4.0K
Insulin is released by beta cells of the pancreas when blood glucose levels are high. It facilitates glucose absorption and utilization in insulin-dependent cells with insulin receptors on their plasma membranes. Insulin promotes glucose uptake by increasing the number of glucose transport proteins in the cell membrane, allowing glucose to enter the cell. As a result, glucose utilization and ATP production are enhanced.
In addition to accelerating glucose uptake and utilization, insulin has...

Diabetes Mellitus: Type 2 and Gestational
2.9K
Type 2 diabetes, characterized by insulin resistance, arises when the insulin receptors on cells lose responsiveness to insulin, diminishing the cell's capacity to take up glucose, resulting in elevated blood glucose levels. To receive a diagnosis of Type 2 diabetes, a series of blood glucose tests are necessary to assess whether the blood glucose falls within normal parameters. If the result is out of the normal range, a patient may be diagnosed as prediabetic or diabetic, depending on the...

Oral Hypoglycemic Agents: Glinides
257
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...

Diabetes Mellitus: Overview and Type I Subtype
3.2K
Diabetes mellitus is a chronic metabolic disorder characterized by high blood glucose levels due to inadequate insulin production, insulin resistance, or both. The condition affects millions worldwide and can significantly impact their health and quality of life.
Type 1 diabetes is an autoimmune disease in which the immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. As a result, the body is unable to produce sufficient insulin, and individuals with...
