摘要
BACKGROUND. Several reports have demonstrated that grafting of autologous melanocytes from normally pigmented donor skin can be used for repigmentation of achromic macules in vitiligo. OBJECTIVE. To investigate a modified approach in which noncultured autologous melanocytes and keratinocytes are grafted on superficially laser dermabraded vitiligo lesions in a suspension enriched with hyaluronic acid. METHODS. Four patients with stable vitiligo were treated using a noncultured melanocyte-keratinocyte suspension. The cellular suspension was grafted on vitiliginous lesions previously dermabraded with a CO2 laser. To improve the viscosity and fixation of the cellular suspension hyaluronic acid was added. Three weeks after grafting, psoralen plus ultraviolet A (PUVA) or ultraviolet B (UVB) therapy was started. Residual leukodermic areas were subsequently retreated. RESULTS. Repigmentation was observed within 2-4 weeks and continued to increase for 3 months after treatment. In all patients, 85-100% repigmentation was achieved. A temporary slight color mismatch was visible in all patients. The most homogeneous repigmentation was obtained 5 months after treatment. CONCLUSION. This modified procedure seems to be a simple and promising treatment for larger vitiliginous areas.
