概括
在患有新型糖尿病的年轻人中使用自动胰岛素的密集治疗改善了葡萄糖控制,但没有保持胰腺β细胞功能. 这一发现凸显了对维护1型糖尿病中的β细胞功能的进一步研究的需要.
科学领域:
- 内分泌学
- 代谢疾病
- 儿童糖尿病研究
背景情况:
- 1型糖尿病 (T1D) 的治疗旨在预防葡萄糖毒性并保持胰腺β细胞功能.
- 之前的研究在实现β细胞保存的严格血糖控制方面遇到了挑战.
- 接近葡萄糖水平的正常化是降低新诊断的T1D中葡萄糖毒性的潜在策略.
研究的目的:
- 评估密集糖尿病治疗在新诊断T1D的年轻人中维护胰腺β细胞功能的有效性.
- 确定自动化胰岛素输送系统是否可以实现葡萄糖水平接近正常化并影响β细胞功能.
- 评估密集血糖控制对儿童T1D中C分泌的长期影响.
主要方法:
- 一项随机双盲临床试验,涉及113名新诊断为T1D的年轻人 (7至17岁).
- 参与者被分配到使用自动化胰岛素输送系统或使用连续血糖监测器的标准护理的密集糖尿病管理.
- 主要测量结果是通过混合食耐受性测试在52周的C曲线下的变化 (AUC).
主要成果:
- 强化治疗组在52周内达到更长的治疗时间 (78%),而不是标准治疗 (64%).
- 在密集治疗和标准治疗组之间没有观察到CAUC下降的显著差异 (P=. 89).
- 这两组患者的严重低血糖和糖尿病酸症的发病率相似.
结论:
- 强化糖尿病管理,包括自动注射胰岛素,有效改善新诊断T1D的青少年的血糖控制.
- 这种密集的方法在52周的胰腺β细胞功能 (C-分泌) 保存方面没有显著的益处.
- 除了在儿童T1D中实现出色的葡萄糖控制之外,还需要进一步的策略来保护β细胞功能.

Diabetes Mellitus: Type 2 and Gestational
2.6K
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
2.8K
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...

Carbohydrate Metabolism

Carbohydrates are polymers composed of molecules containing atoms of carbon, hydrogen and oxygen. One gram of carbohydrate can provide four kilo-calories of energy, which makes it the most efficient instant energy source.
Starch accounts for approximately 60% of the carbohydrates consumed by humans. Since amylase enzymes cannot function in the stomach's acidic environment, starch can only be digested in the mouth and small intestine. Simple sugars are found naturally in milk and fruits in...

Glucose Homeostasis: Pancreatic Islets and Insulin Secretion
1.4K
The pancreatic islets comprising only 1%-2% of the volume are highly vascularized and innervated mini-organs. They contain five endocrine cell types, including β cells that secrete insulin, which is synthesized as a single polypeptide chain, preproinsulin, processed to proinsulin, and finally to insulin and C-peptide. This process is complex and regulated, involving the Golgi complex, the endoplasmic reticulum, and the secretory granules of the β cell.

Diabetes: Management and Pharmacotherapy
324
The therapy for diabetes aims to alleviate hyperglycemia-related symptoms, prevent acute metabolic decompensation, and reduce chronic end-organ complications. Glycemic control is evaluated through short-term (self-monitoring, continuous glucose monitoring) and long-term (A1c, fructosamine) metrics, enabling near real-time tracking of blood glucose levels and reflecting glycemic control over specific time frames.

Insulin: Dosing Regimen and Adverse Effects
223
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...
