白癜风患者身体不同部位中波紫外线最小红斑量的比较

Comparison of minimal erythema dose at different body sites of vitiligo patients

目的:研究白癜风患者不同部位皮肤经中波高能紫外线照射后产生最小红斑量的差异,指导临床治疗剂量的选择。方法:采用中波高能紫外线治疗仪对52例白癜风患者的前臂、小腿、腹部及背部不同部位的皮肤分别进行照射。结果:前臂、小腿、腹部和背部照射后最小红斑量相比较,差异具有统计学意义。结论:由于白癜风患者不同部位皮肤的最小红斑量有差异,因此临床采用中波高能紫外线治疗时,应根据不同部位的最小红斑量选择适当的起始剂量,以达到最佳疗效。

Objective： To compare the difference of minimal erythema dose （MED） induced by UVB of dualight targeted phototherapy system at different body sites of vitiligo patients. Methods： MEDs on the forearm, calf, abdomen and back were assessed in 52 vitiligo patients following irradiation with UVB of Dualight targeted phototherapy system. Results： The differ- ences of the MED among the four body sites were significant. Conclusion： Because of variation of MED with the body sites in vitiligo patients, the initial therapeutic dose of dualight targeted phototherapy system should be determined according to body sites in order to obtain best therapeutic benefit.
