摘要
目的探讨银屑病患者皮肤屏障功能受损的实验依据,以指导临床辅助治疗银屑病。方法 60例银屑病患者运用无创性皮肤生理功能测试仪检测皮损角质层含水量、皮脂含量及经表皮水分流失(TEWL)。电镜观察皮损处细胞超微结构,同时运用免疫组化方法检测皮损处酸性神经酰胺酶的表达。结果与正常皮肤比较,银屑病皮损角质层含水量降低(P<0.01),TEWL值增加(P<0.01),皮脂含量差异无统计学意义。电镜下,皮损颗粒层角质形成细胞中板层小体数量较正常对照组减少,分布紊乱,体积大小不等;免疫组化染色显示酸性神经酰胺酶表达明显减少。结论银屑病皮肤屏障功能明显受损,因此,恢复皮肤屏障功能,加强保湿是银屑病重要的辅助治疗手段之一。
