慢性溃疡的修复往往由于局部组织的缺乏和不良的总体条件而受到阻碍。保守性的清创方法和先进的药物,如聚氨酯泡沫,作为主要手段。然而,愈合过程往往很慢,从而增加了感染或其他并发症的风险。既往研究报道,猪真皮(PD)和添加多核苷酸的透明质酸(PAHA)可以加速慢性溃疡的愈合。近日,发表于Int Wound J的一项随机试验比较了PD、PAHA和聚氨酯泡沫对慢性溃疡的疗效。

研究纳入30名患者,随机分为3组:第1组使用高级药物治疗,第2组使用PD,第3组使用PAHA。在治疗前和30天的随访中,进行了标准化的照片和活检。对照片进行处理以计算出伤口面积。标本用苏木精/伊红、马松三色染色,并对CD34、α-平滑肌肌动蛋白(α-SMA)、I型和III型胶原蛋白、Ki67进行免疫组化。

 

结果显示,与使用聚氨酯泡沫治疗的患者相比,使用PD和PAHA治疗的患者的再上皮化面积更大(分别为P < .05和P < .01)。使用PD和PAHA治疗的患者标本显示出更多的肌成纤维细胞(α-SMA+,P < .01)、新血管生成(CD34+,P < .01)、增殖的真皮细胞(Ki67+,P < .01)、增殖的角质细胞(Ki67+,P < .01)和1型胶原蛋白沉积(P < .05)。PD和PAHA之间没有发现差异。

综上所述,该研究结果表明,PD和PAHA在治疗慢性溃疡方面比聚氨酯泡沫更有效。这些方法是解决这类疾病的一种有效手段。
