概括
早期患有1型糖尿病 (T1D) 的青少年比患有T1D的成年人具有更好的胰岛素敏感性 (SI). 这表明SI在1型糖尿病中随着时间的推移而恶化,影响葡萄糖代谢.
科学领域:
- 代谢研究研究 代谢研究
- 内分泌学 在内分泌学.
- 儿科糖尿病 儿科糖尿病
背景情况:
- 已知胰岛素敏感性 (SI) 在1型糖尿病 (T1D) 患者中随年龄而变化.
- 了解这些与年龄相关的差异对于在不同生命阶段有效管理T1D至关重要.
研究的目的:
- 为了比较被诊断为1型糖尿病 (T1D) 的青少年和成年人之间的食后葡萄糖代谢和胰岛素敏感性 (SI).
主要方法:
- 一项涉及三个组的横截面研究:T1D (T1D-adol) 的早期青少年,T1D (T1D-adult) 的成年人和没有糖尿病 (ND) 的年龄相匹配的成年人.
- 利用三重标志物混合食和口服葡萄糖建模技术来评估SI和葡萄糖周转.
- 吃饭后的葡萄糖,胰岛素和葡萄糖素外游,与内源性葡萄糖生产和葡萄糖消失率进行比较.
主要成果:
- 与非糖尿病对照组相比,两组T1D患者的食后葡萄糖外流量都较高,但T1D青少年和成年人之间没有显著差异.
- 在T1D青少年和成年人之间,胰岛素外流是相似的,但低于对照组.
- 在T1D青少年和非糖尿病对照人群中,胰岛素敏感性 (SI) 类似,但明显高于T1D成人.
- 与T1D成年人和对照人群相比,T1D青少年的葡萄糖水平较低.
结论:
- 在1型糖尿病 (T1D) 的青少年和成年人之间,在食后葡萄糖周转和胰岛素敏感性 (SI) 中存在显著差异.
- 观察到的差异可能部分归因于青少年糖尿病的持续时间较短.
- 研究结果支持这样的假设:随着T1D持续时间的延长,内源性葡萄糖的产生增加,胰岛素敏感性恶化.

Insulin: Dosing Regimen and Adverse Effects
161
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...

Diabetes Mellitus: Type 2 and Gestational
2.3K
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...

Diabetes Mellitus: Overview and Type I Subtype
2.5K
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...

Oral Hypoglycemic Agents: Glinides
149
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: Symptoms, Diagnosis, and Complications
520
For most patients, experiencing several weeks of polyuria, polydipsia, fatigue, and significant weight loss may indicate the presence of diabetes. Furthermore, adults displaying the phenotypic appearance of type 2 diabetes (particularly those who are obese and not initially insulin-requiring), may have islet cell autoantibodies, suggesting autoimmune-mediated β cell destruction and a diagnosis of latent autoimmune diabetes of adults (LADA). The categorization of glucose homeostasis is...

Glucose Homeostasis: Regulation of Blood Glucose
1.5K
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...
