The value of adding platelet‐rich plasma (PRP) to noncultured epidermal cell suspension (NCECS) in surgical treatment of stable resistant vitiligo: A self‐controlled randomised double‐blinded study.

Background: Noncultured epidermal cell suspension (NCECS) is a commonly used surgical treatment for resistant stable acral vitiligo and vitiligo overlying joints. Platelet‐rich plasma (PRP) has been reported to enhance the repigmentation response of different therapeutic modalities for vitiligo, including vitiligo surgery. Objective: To assess the value of adding of PRP to NCECS in the surgical treatment of acral vitiligo and vitiligo overlying joints. Patients and Methods: This self‐controlled randomised trial included 15 patients with 30 lesions in which NCECS suspended in PRP was performed for one lesion and NCECS in ringer's lactate for another comparable lesion. Following NCECS, patients underwent thrice weekly excimer light sessions for 3 months. After 8 weeks, patients underwent preliminary assessment. By the end of the 3 months, both lesions were compared as regards improvement in surface area and pigmentation. Additionally, physician global assessment was made by a blinded investigator. Results: Significant improvement was reported in both lesional extent and pigmentation (after PRP and lactated ringer NCECS) with no statistical difference between them. Conclusion: Despite previous promising results, suspending NCECS in PRP offered no privilege in surgical treatment of acral vitiligo and vitiligo overlying joints, which are quite resistant to treat.
