Fractional CO2 Laser vs Dermabrasion With 5-Fluorouracil for Acquired Leukoderma

2026年9月20日 更新者:Walaa Ashraf Sayed、Al-Azhar University

Fractional Co2 Laser vs Dermabrasion 5-Flurouracil Delivery in Acquired Leukoderma: A Comparative Study

This randomized controlled prospective single-blinded comparative clinical study aims to compare the efficacy and safety of fractional carbon dioxide (CO2) laser therapy versus mechanical dermabrasion, both combined with topical 5-fluorouracil, in the treatment of acquired non-vitiligo leukoderma. The study will evaluate repigmentation, clinical improvement, patient satisfaction, and treatment-related adverse effects.

研究概览

详细说明

'Non-vitiligo leukoderma represents a heterogeneous group of acquired hypopigmentary disorders that may occur following burns, inflammatory dermatoses, trauma, or other cutaneous insults. Treatment can be challenging because of altered skin architecture, scar formation, and impaired melanocyte function or availability.

This randomized controlled prospective single-blinded comparative clinical study will include 16 patients with acquired non-vitiligo leukoderma recruited from the outpatient clinic of Al-Azhar University Hospital (Assiut). Eligible lesions will be treated using either fractional carbon dioxide (CO2) laser therapy followed by topical 5-fluorouracil or mechanical dermabrasion followed by topical 5-fluorouracil. Random allocation will be performed using a computer-generated random allocation sequence.

Fractional CO2 laser sessions will be performed at 4-6-week intervals, with a total of 3-4 sessions. Mechanical dermabrasion will be performed until pinpoint bleeding appears, followed immediately by topical 5-fluorouracil application, with a total of 3-4 sessions. Similar post-procedure care will be provided.

Treatment outcomes will be assessed using objective and subjective measures, including the Vancouver Scar Scale, Vitiligo Analysis by Computer Assisted Grid (VACAG), assessment of treatment-related adverse effects, physician assessment of clinical improvement using the Mean Improvement Score by Physician (MISP), standardized clinical photography, and patient satisfaction using a 10-point visual analogue scale. Adverse effects such as infection, scarring, Koebner phenomenon, aggravation of depigmentation, pain, burning sensation, erythema, and edema will be documented.

The study will be conducted after approval by the local Ethics Committee of the Faculty of Medicine, Al-Azhar University, Assiut. Written and verbal informed consent will be obtained from participating patients, and privacy of the collected data will be maintained.'

干预/治疗
实验性的:Fractional CO2 Laser + 5-Fluorouracil

Patients will receive fractional carbon dioxide (CO2) laser therapy followed by topical 5-fluorouracil. Laser parameters will be adjusted according to the site and size of the lesions. Treatment sessions will be performed at 4-6-week intervals for a total of 3-4 sessions. Post-procedure care will include topical antibiotic ointment and emollients.

Fractional carbon dioxide (CO2) laser therapy followed by topical 5-fluorouracil application. Laser parameters will be adjusted according to lesion size and site.

Topical 5-fluorouracil applied immediately after fractional CO2 laser or dermabrasion according to the assigned study arm.

有源比较器:Dermabrasion + 5-Fluorouracil

Patients will undergo mechanical dermabrasion using manual or motor-driven dermabrasion until the appearance of pinpoint bleeding, followed immediately by topical 5-fluorouracil application. A total of 3-4 sessions will be performed. Similar post-procedure care will be provided. �
