概括
与葡萄糖问题相关的小纤维神经病变 (SFN) 显示出较高的角膜树突细胞密度 (DCD). 这种DCD增加的葡萄糖耐受性损害 (IGT) 可能是早期神经损伤的信号.
科学领域:
- 神经学 神经学
- 眼科医生 眼科 眼科
- 代谢障碍 代谢障碍 代谢障碍
背景情况:
- 小纤维神经病变 (SFN) 经常与葡萄糖失调有关,包括葡萄糖耐受性损害 (IGT) 和2型糖尿病 (T2D).
- 角膜共聚焦显微镜 (CCM) 是一种有价值的非侵入性技术,用于评估角膜神经完整性和量化角膜树突细胞密度 (DCD).
研究的目的:
- 在被诊断为小纤维神经病变 (SFN) 和不同程度的葡萄糖失调 (IGT或T2D) 的患者中调查和比较角膜树突细胞密度 (DCD).
主要方法:
- 该研究涉及38名患有SFN和葡萄糖失调的患者,51名患有SFN但没有葡萄糖失调的患者,20名健康对照.
- 所有参与者都接受了全面的神经学检查,神经生理学评估和角膜共聚焦显微镜 (CCM).
主要成果:
- 与健康对照组相比,患有SFN和葡萄糖失调的患者表现出明显更高的角膜DCD (p=0.01).
- 与T2D和SFN患者相比,IGT和SFN患者的成熟树突细胞密度更高.
结论:
- 与对照组和已确诊T2D患者相比,IGT患者的角膜DCD升高表明,DCD可以作为葡萄糖失调中神经病变的早期生物标志物.

Diabetic Retinopathy
DefinitionDiabetic retinopathy is a microvascular complication of diabetes affecting the retinal blood vessels.Risk FactorsDiabetic retinopathy is present in almost all individuals with type 1 diabetes and more than 60% of those with type 2 diabetes after two decades of disease.The risk increases with poor glycemic control, hypertension, dyslipidemia, smoking, pregnancy, and puberty.Although cataracts and glaucoma are also more frequent in people with diabetes, retinopathy remains the leading...
Diabetic Neuropathy
DefinitionDiabetic neuropathy is nerve damage caused by long-standing diabetes mellitus. It results directly from prolonged high blood sugar levels.PathophysiologyThe pathophysiology of diabetic neuropathy involves both metabolic and vascular disturbances triggered by chronic hyperglycemia.Metabolic injury: Elevated glucose levels activate the polyol pathway within nerve cells, leading to the accumulation of sorbitol and fructose. This increases oxidative stress, disrupts normal nerve...
