概括
与标准护理 (SOC) 相比,细胞矩阵 (CM) 和非细胞矩阵 (ACM) 产品没有改善糖尿病足的愈合率. 标准护理本身是有效的,并且在治疗这些不愈合的伤口方面可能更具成本效益.
科学领域:
- 再生医学是一种再生医学.
- 伤口愈合 治愈 伤口愈合
- 糖尿病并发症 糖尿病并发症
背景情况:
- 糖尿病足 (DFU) 在伤口护理中构成了重大挑战,往往导致治愈结果差.
- 细胞矩阵 (CM) 和非细胞矩阵 (ACM) 产品用于促进愈合,但它们与DFU的标准护理 (SOC) 的比较疗效需要强大的临床评估.
研究的目的:
- 为了比较细胞矩阵 (CM) 产品与非细胞矩阵 (ACM) 产品在治愈不治愈的糖尿病足的疗效.
- 评估12周内用CM,ACM或SOC治疗的DFU的愈合率和结果.
主要方法:
- 进行了一项随机,单盲,三臂受控试验 (Dermagraft 和 Oasis 纵向比较疗效研究 - - DOLCE).
- 117名患有全厚非愈合糖尿病足的患者随机分配给接受SOC,CM或ACM治疗12周.
- 主要结局是12周内愈合的伤口百分比,次要结局包括28周内愈合和伤口复发.
主要成果:
- 在12周后,CM组的49%,ACM组的69%和SOC组的57% (P = 0.16) 发生了完全的重新表皮化.
- 在28周,治愈率为CM的61%,ACM的56%,SOC的64% (P = 0.78).
- 在三个治疗手臂之间没有观察到愈合率,伤口复发率或不良事件的显著差异.
结论:
- 无论是细胞矩阵 (CM) 还是非细胞矩阵 (ACM) 产品都没有在治疗不治愈的糖尿病足方面表现出与标准护理 (SOC) 相比更高的疗效.
- 调查结果表明,标准护理本身就是DFU的有效治疗策略,并可能减少经济负担.

33
Definition A diabetic foot ulcer (DFU) is a chronic, non-healing wound that develops in individuals with diabetes. It typically occurs on pressure-bearing areas such as the heel, metatarsal heads, or hallux, and carries a high risk of infection and amputation.Pathophysiology • The development of DFUs can be explained by four interconnected mechanisms: neuropathy, ischemia, infection, and impaired wound healing. • Neuropathy is the most common factor.

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...
