To determine the effectiveness of combining laser therapy with an immunosuppressive approach, the investigators recruited 14 subjects, aged 12 to 63 years, with Fitzpatrick skin types II to IV and having had vitiligo for a minimum of three months. A total of 43 vitiliginous lesions were randomized to receive either 308-nm excimer laser monotherapy twice weekly for six weeks or the laser sessions plus topical 0.1% tacrolimus ointment applied twice daily. Treated lesions were matched with untreated lesions on the subjects' opposite side.
为了确定结合雷射治疗与免疫抑制方式的效果,研究人员徵集14位受试者,年龄从12到63岁,患有Fitzpatrick皮肤类型II到VI的、而且有白斑至少3个月以上的患者;总共有43个白斑病灶被随机分派接受每周两次的308-nm准分子雷射治疗持续六周,或是雷射治疗加上0.1%局部tacrolimus软膏每天涂抹两次;治疗后的病灶再与受试者另外一边未接受治疗的病灶相比较。
