[摘要]目的:观察皮肤微针联合5-氟尿嘧啶(5-FU)诱导白癜风复色的疗效。方法:选择稳定期非节段型白癜风15例,共30片白斑皮损。随机分为两组:联合组:15片皮损,给予1.0mm的皮肤微针针刺皮肤联合外涂2.5% 5-FU溶液,局部封包,每2周1次,共6次;对照组:15片皮损,仅予1.0mm微针针刺皮肤,每2周1次,共6次。每次治疗前用透明薄膜描记点计数法(Point counting method)测量白斑面积。结果:两组白癜风皮损经3个月治疗后,联合组总有效率66.7%,明显优于单用微针组的20.0%,两组比较差异具有统计学意义(P<0.05)。结论:皮肤微针联合外用5-FU可诱导白癜风复色,是一种安全有效的治疗方法。

Abstract: Objective  To evaluate the effect of skin microneedling combined with topical 5-fluorouracil in the induction of vitiligo repigmentation. Methods  15 stable non-segmental vitiligo patients with 30 vitiliginous patches were recruited in this study. The 15 vitiliginous patches of combined treatment group were treated with 1.0-mm-depth microneedling and then topically applied with 2.5% 5-fluorouracial solution under occlusive dressing, while the other 15 vitiliginous patches were only treated with 1.0-mm-depth microneedling. This procedure was repeated every 2 weeks for 6 sessions. The area of vitiliginous patches were measured by point counting method before each session. Results   After 3 months of treatment, the effective rate was significantly better in combined treatment group (66.7%) compared with microneedling only group (20.0%) (P<0.05). Conclusion Skin microneedling combined with 5-FU is a safe and effective treatment for inducing repigmentation in vitiligo.

白癜风是一种临床常见的慢性获得性色素脱失性皮肤病,其确切的发病机制并不十分清楚。选择性自身免疫性黑素细胞破坏被认为是导致皮肤斑片状色素脱失的主要病因[1-2]。白癜风发病常见于年轻人,给患者带来沉重的精神负担且导致其生活质量下降[1]。目前临床缺乏单一有效的治疗方法。311nm NB-UVB和308nm准分子光照射等光疗是诱导白癜风复色(Repigmentation)的一线治疗选择[3-4]。然而,有部分白癜风皮损对光疗产生抵抗,又被称之为难治性白癜风(Refractory vitiligo)[5]。近年来,也有报道用点阵CO2激光[6]、磨皮术[7]和微针[8]等手段可诱导这些难治性白癜风成功复色。本研究初步观察了1.0mm皮肤微针联合外用5-氟尿嘧啶(5-FU)治疗白癜风的临床疗效,现将结果报道如下。
