紫外线治疗特应性皮炎的进展
Advances in the treatment of atopic dermatitis with ultraviolet rays
特应性皮炎是一种慢性复发性炎症性疾病,紫外线通过调节T细胞功能及相关炎症介质而取得良好疗效.不同波段紫外线因其特性而应用于不同类型的特应性皮炎:窄谱中波紫外线治疗儿童期特应性皮炎显示出良好疗效及安全性,认为是慢性患者的首选治疗;急性患者首选长波紫外线照射;局限性皮损选择308 nm准分子激光为佳.紫外线治疗特应性皮炎临床尚处于初级阶段,在照射剂量和照射疗程方面,各家报道不一.
更多Atopic dermatitis is a chronic recurrent inflammatory disease.By regulating the function of T cells and related inflammation factors,ultraviolet rays (UV) exert a satisfactory therapeutic effect on atopic dermatitis.Because of distinct characteristics,different spectrum of UV is applicable to specific types of atopic dermatitis.Narrow-band UVB shows good efficacy and safety in the treatment of atopic dermatitis in childhood,and is considered to be the best choice for patients with chronic atopic dermatitis; UVA is the preferred choice for patients with acute atopic dermatitis,and 308-nm excimer laser is suitable for local lesions of atopic dermatitis.However,there has been no uniform standard for the dose and duration of UV irradiation in the treatment of atopic dermatitis.
