Summary

Vitiligo is an acquired pigmentation disorder due to loss of melanocytes characterized by depigmentation macules or patches. One type of this disease is nonsegmental vitiligo (NSV). Until now, there is no satisfactory treatment for vitiligo. Vitiligo therapies are medical therapy include topical and systemic therapy, phototherapy as well as surgery. Surgical treatment is indicated in stable vitiligo, which is not responding to medical treatment. This procedure consists of tissue grafting and cellular transplantation. Mini punch graft (MPG) is the most frequently performed tissue transplantation technique, while cellular transplantation from autologous noncultured extracted hair follicle outer root sheath cell suspension (NCEHFORSCS) containing melanocyte stem cells, is currently a promising option.

Detailed description

Current NSV treatments can be considered suboptimal and leading to decreased patient's quality of life due to the emotional burden of therapy dissatisfaction. When a stable NSV is not responding to medical therapy, surgery may be a useful treatment approach. All surgical techniques in vitiligo treatment share the same principle: transferring autologous melanocytes from a donor to repopulate melanocytes in the depigmented area that lacks a reservoir or fails to activate melanocytes in the outer root sheath (ORS) of hair follicles. MPG as the most frequently performed tissue transplantation technique transferred the epidermal melanocyte to vitiligo lesion, while NCEHFORSCS provides melanocytes with better properties and contains melanocyte stem cells. The advantages of melanocytes from ORS compared to epidermal are the follicular melanocyte:keratinocyte ratio consists of one melanocyte for every five keratinocytes or 1:5 in the hair bulb, melanocytes are more dendritic, have larger melanosomes, and have the potential to produce more melanin pigment. Due to these properties, hair follicles can be a better source of melanocytes than epidermis in the delivery of cellular transplantation-based therapy for vitiligo therapy. Research comparing the effectiveness of the two procedures has never been conducted in Indonesia, even though the incidence of vitiligo is quite high and the success of therapy is still not optimal. So the purpose of this study is to compare the effectiveness of the two procedures in NSV patient.

Conditions

• Non Segmental Vitiligo

Interventions

Type	Name	Description
PROCEDURE	NCEHFORSCS transplantation	One vitiligo lesion of participans treated with NCEHFORSCS transplantation including follicle unit extraction (FUE) procedure from the occipital area, laboratory procedure for preparation of cell suspension, and transplantation of NCEHFORSCS.
PROCEDURE	MPG procedure	Another vitiligo lesion treated with MPG procedure Follow up The dressing was removed by the researcher on day 8 The participants were asked to attend for follow-up at the clinic on week 2, 4, 8, 12, and 16 after the two procedure were done. At 2, 4, 8, 12 and 16 weeks of follow-up visits, any possible complications were evaluated and digital photographs of the lesions were taken for evaluating the two procedure efficacy using its parameter: appearance of repigmentation (AOR), total number of repigmentation NSV lesions, extent area of repigmentation, and color match
