A COMPARATIVE STUDY BETWEEN RECEPIENT SITE PREPARATION USING DERMABRASION, LIQUID NITROGEN INDUCED BLISTER AND DERMAROLLING SYSTEM IN AUTOLOGOUS NON CULTURED EPIDERMAL CELL SUSPENSION PROCEDURE IN STABLE VITILIGO PATIENTS

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

With a sample size of 36, 3 patches of a single stable vitiligo patient will be prepared using dermabrasion,dermaroller system and liquid nitrogen induced blister. The autologous non cultured epidermal cell suspension will be prepared using cold trypsinization from the skin graft taken from patient.After preparation of the recipient site,the suspension is applied and dressing is done.The patient is followed up for 3 months and extent of repigmentation,colour match,pattern of repigmentation,patient satisfaction score, vitiligo quality of life index before and after surgery and effect on acral vs non acral regions are studied for all the 3 methods.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Dermabrasion with NCES

Intervention-Dermabrasion with autologous non cultured epidermal cell suspension Recipient site preparation using dermabrasion followed by autologous non cultured epidermal cell suspension technique of 1 stable vitiligo patch of each of the 36 patients.

Group Type ACTIVE_COMPARATOR

Dermabrasion with NCES

Intervention Type PROCEDURE

1. The recipient site will be shaved, cleaned with betadine and surgical spirit and anaesthetized with mixture of 2% lignocaine and NS (1:1).
2. Dermabrasion will be done using Manekshaw's dermabrader until tiny pinpoint bleeding spots are seen and extended 5mm beyond margins to prevent halo phenomenon.
3. The denuded area will be washed with PBS and covered with a PBS moistened gauze piece.
4. With 18 G needle attached to tuberculine syringe, few small drops of non cultured epidermal cell suspension will be placed over the denuded surface and spread evenly.
5. Dressing is done in 4 layers in order-collagen(Neuskin F), bactigras, cutisoft(sterile gauze) and dynaplast (elastic plaster).

Dermaroller with NCES

Intervention-Dermaroller with autologous non cultured epidermal cell suspension Recipient site preparation using dermaroller system followed by autologous non cultured epidermal cell suspension technique of 1 stable vitiligo patch of each of the 36 patients.

Group Type ACTIVE_COMPARATOR

Dermaroller with NCES

Intervention Type PROCEDURE

1. The recipient site will be shaved, cleaned with betadine and surgical spirit.
2. Microneedling will be done with a device containing 540 microneedles in 8 rows, each 0.25 mm in length. Microneedling will be extended 5 mm beyond margins to prevent halo phenomenon.
3. The roller will be passed repeatedly over the skin in a star-shaped way for about 10 minutes
4. The noncultured epidermal cell suspension will be carefully transferred to a tuberculin syringe.
5. NCES will be applied to the skin surface with a tuberculin syringe with an 18G needle and spread evenly after dermarolling treatment.
6. Dressing is done in 4 layers in order-collagen(Neuskin F), bactigras, cutisoft(sterile gauze) and dynaplast (elastic plaster).

Liquid nitrogen induced blister with NCES

Liquid nitrogen induced blister with autologous non cultured epidermal cell suspension Recipient site preparation using liquid nitrogen induced blister followed by autologous non cultured epidermal cell suspension technique of 1 stable vitiligo patch of each of the 36 patients.

Group Type ACTIVE_COMPARATOR

Liquid nitrogen induced blister with NCES

Intervention Type PROCEDURE

1. The recipient site will be shaved, cleaned with betadine and surgical spirit and anaesthetized with mixture of 2% lignocaine and NS (1:1).
2. The site to be grafted is outlined with a surgical marking pen.
3. To induce blisters on the achromic areas, freezing with liquid nitrogen spray was performed during 10 to 20 seconds inside round circles previously drawn on the skin.
4. The patient is asked to visit 24 hours later.
5. The blister fluid is aspirated and NCES taken in tuberculin syringe with 18 G needle is injected into it such that the blister roof is preserved.
6. Dressing is done in 4 layers in order-collagen(Neuskin F), bactigras, cutisoft(sterile gauze) and dynaplast (elastic plaster).
