Recipient site preparation is a crucial step in non-cultured epidermal cell suspension (NCES) as it facilitates proper uptake of the grafted melanocytes.
To compare the repigmentation rate of recipient sites prepared with manual dermabrasion (MD) versus electrofulguration-assisted dermabrasion (EF) in patients undergoing NCES for treatment of stable vitiligo.
This was a prospective randomized study including 26 patients of stable vitiligo (VIDA 0 or -1), each having two patches of size greater than 3 × 3 cm located symmetrically or at the same site or a single patch of 6 × 6 cm or larger. After randomization of patches in the given patient, MD and EF were performed on recipient areas followed by NCES. The patients were followed up at 4 weekly intervals up to 24 weeks and assessed for extent of repigmentation and adverse effects if any.
Greater than 75% repigmentation was observed in 69.3% of the patches prepared by MD as compared to 73.1% patches prepared by EF at the end of 24 weeks (p = 0.791). The mean improvement in target VASI was 64.0% in the MD group as compared to 68.8% in the EF group (p = 0.21). Patches prepared by EF achieved successful repigmentation earlier as compared to patches prepared by MD (9.4 weeks vs 11.4 weeks, p = 0.12).
Both MD and EF have comparable outcomes with respect to all parameters.
受区准备是无细胞表皮细胞悬浮液(NCES)移植的关键步骤,因为它有利于移植黑素细胞的适当摄取。
比较手工磨皮(MD)和电灼辅助磨皮(EF)在接受 NCES 治疗稳定型白癜风患者中的受区再色素沉着率。
这是一项前瞻性随机研究,包括 26 例稳定型白癜风患者(VIDA0 或-1),每位患者有两个大于 3×3cm 的斑块,位于对称或同一部位,或一个 6×6cm 或更大的斑块。在给定患者的斑块随机分组后,对受区进行 MD 和 EF 处理,然后进行 NCES。患者每 4 周随访一次,随访 24 周,评估再色素沉着程度和任何不良反应。
在 24 周结束时,MD 制备的斑块中有 69.3%观察到超过 75%的再色素沉着,而 EF 制备的斑块中有 73.1%(p=0.791)。MD 组的目标 VASI 平均改善率为 64.0%,而 EF 组为 68.8%(p=0.21)。与 MD 制备的斑块相比,EF 制备的斑块更早获得成功再色素沉着(9.4 周与 11.4 周,p=0.12)。
MD 和 EF 在所有参数方面的结果都具有可比性。
