概括

在2型糖尿病患者中,血清沙科辛水平与糖尿病视网膜病变 (DR) 相反相关. 较高的萨科辛,特别是较低的HDL-C,显著降低了DR风险,这表明了新的预防目标.

科学领域:

代谢学代谢学代谢学
生物化学生物化学
眼科医生眼科眼科

背景情况:

糖尿病视网膜病变 (DR) 是导致2型糖尿病 (T2D) 视力丧失的主要原因.
确定DR风险分层的生物标志物对于有效管理至关重要.
血清代谢物可能提供对DR病原学的见解.

研究的目的:

研究2型糖尿病 (T2D) 患者的血清沙科辛水平与糖尿病视网膜病变 (DR) 的存在之间的关联.
探索萨科辛作为DR风险生物标志物的潜力.
了解萨科辛与其他因素 (如HDL-C) 在DR发育中的相互作用.

主要方法:

在69对有DR和没有DR的T2D患者中分析了血清代谢物,其关键临床参数相匹配.
使用权重基因同表达网络分析 (WGCNA) 和途径分析来确定相关的代谢物和途径.
限制立方线和条件逻辑回归模型被用来量化萨科辛和DR之间的关联.

主要成果:

血清萨科辛的四分位数间范围增加与DR几率显著降低67%有关 (AOR:0.33).
与最低三分之一相比,萨科辛的较高三分之一显示DR的几率逐渐降低.
最低的DR几率观察到的是患有较高的萨科辛和较低的HDL-C水平 (OR:0.13) 的患者.

结论:

血清沙科辛与T2D患者的糖尿病视网膜病变相反相关.
萨科辛对DR的保护作用在缺乏HDL-C的个体中更为明显.
萨科辛可能是DR的新型治疗或预防标,增强精准医学方法.

关键词:

糖尿病视网膜病变 - 糖尿病视网膜病变在WGCNA中,WGCNA是WGCNA.倾向性得分匹配的比分匹配萨尔科辛 (sarcosine) 是一种类型的氨酸.

Pathophysiology of Diabetes

Pathophysiology of Diabetes

Diabetes mellitus is a chronic metabolic disorder characterized by hyperglycemia. The four categories of diabetes are type 1 diabetes, type 2 diabetes, other specific types of diabetes, and gestational 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,...

Diabetes Mellitus: Type 2 and Gestational

Diabetes Mellitus: Type 2 and Gestational

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...
