概括
在得到良好控制的2型糖尿病 (T2DM) 患者中,血糖变异性 (GV) 高,即使HbA1c水平正常. 持续血糖监测 (CGM) 显示了血糖的波动,表明需要先进的糖尿病管理.
科学领域:
- 内分泌学 在内分泌学.
- 代谢疾病 代谢疾病
- 医疗技术 医疗技术 医学技术
背景情况:
- 传统的血糖控制指标,如HbA1c,无法捕捉短期的葡萄糖波动.
- 持续血糖监测 (CGM) 系统提供了对血糖变化 (GV) 的详细见解.
- 即使在看似控制的HbA1c水平的患者中,GV也可能导致糖尿病并发症.
研究的目的:
- 为了评估2型糖尿病 (T2DM) 患者的血糖变异性 (GV),使用闪光CGM控制HbA1c.
- 在这个患者队列中评估GV和HbA1c水平之间的相关性.
- 突出GV的临床意义,超越传统的血糖标记.
主要方法:
- 一项前性观察性研究,涉及30名T2DM患者,HbA1c在6.5%至7.5%之间.
- 使用FreeStyle® Libre ProTM闪光CGM系统进行为期7天的葡萄糖监测.
- 分析CGM数据,使用标准偏差 (SD),百分比变化系数 (%CV),上/下/范围内的时间 (TAR,TBR,TIR) 等指标,%CV量化GV.
主要成果:
- 很大一部分患者表现出高或非常高的GV (%CV>20%).
- 在HbA1c和%CV之间没有发现显著的相关性 (p=0.690).
- 在%CV和TIR (负,p<0.001) 和%CV与TAR和TBR (阳性,p<0.001) 之间观察到显著的相关性.
结论:
- 闪光CGM揭示了T2DM患者的显著血糖变异,这些患者被认为HbA1c控制得很好.
- 用%CV测量的GV是并发症的独立风险因素,不仅反映在HbA1c上.
- 来自CGM的GV指标为优化糖尿病管理和治疗决策提供了更全面的评估.

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: Management and Pharmacotherapy
266
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.

Diabetes Mellitus: Overview and Type I Subtype
2.6K
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...

Hypoglycemia and Glucagon
257
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...

Diabetes: Symptoms, Diagnosis, and Complications
526
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...

Carbohydrate Metabolism
11.0K
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...
