外用糖皮质激素对老年性干皮症患者皮肤屏障功能的影响

目的 评价外用糖皮质激素对老年性干皮症患者皮肤屏障的影响.方法 32例老年性干皮症患者一侧前臂外用0.1％氢化可的松乳膏(实验组),每日1次,持续8周,于第O、2、4、8周进行随访评价,并以用药前后另一侧手臂作为对照(对照组).皮肤屏障功能评价内容包括检测角质层含水量及经表皮水分丢失(TEWL)值.结果 实验后2周,实验组角质层含水量最高,而TEWL值最低.实验后8周,实验组角质层含水量高于对照组(P＜0.01),且TEWL值低于对照组(P＜0.01).结论 外用糖皮质激素对于老年性干皮症患者用药8周时,未观察到皮肤屏障功能破坏;用药2周时对皮肤屏障功能有暂时改善作用.

Effect of topical glucocorticoid on skin barrier function of patients with senile xerosis

Objective To evaluate the effect of topical glucocorticoid on skin barrier function of patients with senile xerosis. Methods A total of 32 patients were treated with 0.1% topical hydrocortisone cream on one side of the forearms (topical hydrocortisone group), once a day for 8 weeks, and the other forearms were taken as control (control group). Skin barrier function was evaluated at 0, 2, 4 and 8 weeks after experiment using Corneometer and Tewameter. Results The water content of stratum corneum in the topical hydrocortisone group peaked at 2 weeks, while the transepidemal water loss (TEWL) value was the lowest. Compared with the control group, topical hydrocortisone significantly increased the water content of the stratum corneum (P<0.01) and decreased the TEWL value of stratum corneum (P<0.01) after an 8-week treatment. Conclusion The application of topical glucocorticoid in patients with senile xerosis results in no impairment of skin barrier function after an 8-week treatment, and it can temporarily improve the skin barrier function after 2-week treatment.
