The methoxypsoralen-ultraviolet A-light (PUVA)-induced pigmented epidermal grafting procedure appears to be a more effective treatment for vitiligo than similar treatments presently available. This finding was based on: 1) a more vigorous and completely homogeneous repigmentation was observed in the vitiliginous area and 2) that the treatment was safe, easy, inexpensive, and not time-consuming (approximately 3-4 hours), thus making it a suitable outpatient clinic treatment procedure for vitiligo patients.
Twenty-eight patients with amelanotic depigmented lesions that had been refractory to conventional therapy were treated using suction blisters from autologous epidermal sheets. These had 8-methoxypsoralen (8-MOP) solution applied and had been exposed to ultraviolet A light (topical PUVA) in order to stimulate melanogenesis.
Successful repigmentation was obtained after transplantation in all patients with segmental and localized vitiligo. The most homogeneous repigmentation was obtained within 3 months after grafting.
This novel procedure is an excellent tool by which to treat segmental and localized vitiligo lesions that have failed to respond to other therapies.
甲氧沙林-紫外线A光(PUVA)诱导的色素沉着表皮移植手术似乎是一种比目前可用的类似治疗方法更有效的白癜风治疗方法。这一发现基于:1)在白癜风区域观察到更强烈且完全均匀的色素再生;2)该治疗安全、简便、廉价且不耗时(约3-4小时),因此使其成为适合白癜风患者的门诊治疗方法。
28例对传统治疗无效的无色素脱色素性病变患者,使用自体表皮片的吸引水疱进行治疗。这些表皮片涂抹了8-甲氧沙林(8-MOP)溶液,并接受紫外线A光照射(外用PUVA)以刺激黑素生成。
所有节段性和局限性白癜风患者移植后均成功实现色素再生。移植后3个月内色素再生最为均匀。
这种新方法是治疗对其他疗法无反应的节段性和局限性白癜风病变的极佳工具。
