概括
二甲酸盐 (CaD) 治疗改善了糖尿病视网膜病变 (DR) 患者的黄斑微循环,增强了表面和深层血管复合体. 即使在较先进的DR阶段,CAD也显示出有效性.
科学领域:
- 眼科医生 眼科 眼科
- 医学研究 医学研究
背景情况:
- 糖尿病视网膜病变 (DR) 是导致视力丧失的主要原因.
- 视网膜的微血管变化是DR的标志.
- 评估这些变化对于了解疾病进展和治疗疗效至关重要.
研究的目的:
- 评估二甲酸盐 (CaD) 对糖尿病视网膜病变 (DR) 患者的黄斑微血管结构的影响.
- 为了比较DR患者的微血管变化,用CaD治疗的患者与未接受治疗的患者相比.
主要方法:
- 追溯性研究比较了两组DR患者:一组接受1g/天CaD治疗 (第一组) 和一组对照 (第二组).
- 光学连贯断层扫描血管学 (OCTA) 用于评估表面血管复合体 (SVD) 和深血管复合体 (DVD) 中的血管密度.
- 患者在基线,3个月和6个月被检查;通用线性混合模型分析了随时间变化.
主要成果:
- 第1组 (接受CaD治疗) 从基线到3个月显示SVD和DVD显著增加 (分别P=0.021和P=0.007).
- 在研究期间,在第二组 (未接受治疗) 中没有观察到SVD或DVD的显著变化 (分别P=0.175和P=0.156).
- 严重程度的DR显着与SVD的变化相关,在CAD治疗组 (P=0.016).
结论:
- 二酸盐 (CaD) 的使用对DR患者的黄斑微循环产生了积极的影响.
- 在改善视网膜微血管结构方面,即使在糖尿病视网膜病变的更先进阶段,CAD也表现出有效性.

2.4K
Calcium ions are essential to contract smooth muscle cells in blood vessels. They enter these cells through voltage-dependent calcium channels, specifically L-type calcium channels in the cell membrane. These L-type calcium channels are integral to the excitation-contraction coupling process in smooth muscle. When a stimulus is received by smooth muscle cells, their membrane depolarizes. This alteration in membrane potential instigates the opening of L-type calcium channels. As a result,...

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...
