Advances in the treatment of atopic dermatitis with ultraviolet rays

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.
