Brief Summary

The aims of this study are to:- Compare the effect of fractional Erbium: YAG laser assisted delivery of platelet- rich plasma versus microneedling with platelet-rich plasma in the induction of skin repigmentation in localized stable vitiligo patients.

Detailed Description

Vitiligo is a depigmentation disease characterised by epidermal melanocyte death and melanin loss. It affects less than 0.1% to greater than 8% of the world's population. It is caused by a dynamic interplay between genetic and environmental risks that initiates an autoimmune attack on melanocytes in the skin. There are some treatment modalities, such as topical steroids, topical calcineurin inhibitors, excimer laser, narrowband-ultraviolet B therapy (NB-UVB), vitamin D,and non-cultured epidermal cell suspension (NCES).

One of the representative autogenous regenerative biomaterials is platelet-rich plasma (PRP) which contains moderate to high concentrations of platelets together with multiple biomolecules and moderate concentrations of leucocytes. Activated platelets can release autogenous growth factors that may initiate a signalling cascades and lead to numerous intracellular changes, promoting the proliferation, migration, and differentiation of stem cells and regulating local inflammation and immune responses.

Laser- assisted drug delivery (LADD) functions by creating focused zones of selective epidermal damage thereby rendering the dermis more accessible to topical medication.

Multiple lasers have been applied for the purpose of LADD, including ablative fractional carbon dioxide (CO2) and erbium-doped yttrium-aluminum-garnet (Er: YAG) lasers.

Microneedling (Mn) is a minimally invasive process in which many tiny needles penetrate the skin. It augments transdermal drug delivery (TDD) through the creation of pores in the stratum corneum. This technique is also believed to induce pigmentation by physically moving melanocytes with the needles into the vitiligo areas from the pigmented areas, so that they may serve as reservoirs for melanogenesis, also it induces microinflammation which stimulates the migration of keratinocytes and melanocytes that induces the release of cytokines and growth factors stimulating melanocytes at the periphery of vitiligo patches and their migration from pigmented to unpigmented areas.

Conditions

Study Design

• Allocation Method: RANDOMIZED
• Intervention Model: PARALLEL
• Primary Study Purpose: TREATMENT
• Blinding Strategy: NONE

Study Groups

fractional(Er: YAG) laser with platelet-rich plasma

Subjected to fractional erbium: yttrium-aluminum-garnet (Er: YAG) laser (FotonaXs

• Dynamis, Slovenia) with the energy of 1400 mJ in short pulse mode (SP) with spot size of 7 mm diameter, frequency of 3 Hz, and pixel 1. PRP is applied over the treated areas.This procedure will be repeated every two weeks for six months

Group Type: EXPERIMENTAL

Microneedling with platelet-rich plasma

Subjected to microneedling using electronic dermapen device (Dr Pen Derma Pen Ultima A6®) which has a disposable head that personalized for each patient and sterilized after each session. The derma pen will penetrate the skin with variable depths ranging from 0.25 to 0.5 mm (not more than the depth of the epidermis). It will pass vertically over the vitiligo area in a circular pattern from the perilesional areas toward the depigmented center until pinpoint bleeding appears then the PRP is applied over the treated areas.

• This procedure will be repeated every two weeks for six months.
