1型糖尿病 (T1D) 中的心脏自主神经病变 (CAN) 与特定的代谢变化有关,包括较低的氨基酸和较高的乳酸. 这些发现突出了T1D患者中CAN的潜在生物标志物.
科学领域:
- 内分泌学 在内分泌学.
- 代谢学 代谢学 代谢学
- 心血管科学 心血管科学
背景情况:
- 性变态影响1型糖尿病 (T1D) 的心血管风险,女性经历更高的宏血管事件率,特别是绝经后.
- 心脏自主神经病变 (CAN) 是T1D的常见并发症,导致不良的心血管结果.
- 假设中间代谢异常与T1D中的CAN有关.
研究的目的:
- 调查低分子量代谢物 (LMWM) 与T1D中的CAN之间的关联.
- 探索性变态和年龄对癌症T1D患者的LMWM个人资料的影响.
- 为了确定T1D中CAN的潜在LMWM生物标志物.
主要方法:
- 对323名T1D受试者 (147名女性,176名男性) 的横截面研究.
- 通过Ewing的心血管反射测试来评估CAN.
- 通过质子核磁共振光谱 (1H-NMR) 分析的血清代谢物.
主要成果:
- 与没有CAN的患者相比,患有CAN的患者表现出较低的氨酸,单氨酸和三氨酸水平,以及较高的乳酸盐水平,独立于BMI和eGDR.
- 后勤回归确定了异黄素,年龄,A1c和微血管病变作为CAN的重要决定因素.
- 性别影响了LMWM概况,但在代谢学上没有发现CAN和性别,或性别,年龄和CAN之间的相互作用.
结论:
- LMWM水平与T1D中的CAN有关.
- 特定的氨基酸和乳酸可以作为CAN的潜在生物标志物.
- 虽然性变态影响代谢物概况,但它似乎不会与T1D中的CAN相互作用.

Diabetes Mellitus: Overview and Type I Subtype
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...
Pathophysiology of Diabetes
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility,...
Carbohydrate Metabolism
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...
