Özet
Objective: Evaluate the treatment outcome of vitiligo patients receiving a standard regimen of high-dose biweekly fractional 2940 nm erbium:yttrium aluminium garnet (YAG) laser applications as an add-on to various treatment modalities. Materials and methods: The authors extracted the study population’s clinical images before treatment and 3rd-month control from their clinical archive and used the medical records. The primary outcome measure was 50% repigmentation at 3rd-month follow-up. Institutional ethical committee approved the study. Results: Of the evaluated 28 patients, 18 were eligible with 31 treatment regions. All patients received at least one topical agent [steroids, calcineurin inhibitors, or 5-fluorouracil (5-FU)] and 11 patients received either targeted ultraviolet B (UVB) or narrow-band UVB. Of the 31 study regions, 88.8% (8/9) of facial; 77.7% (7/ 9) of dorsal hand; 75% (3/4) of limb; and 25% (2/8) of finger lesions achieved 50% repigmentation at 3rd-month control. The facial and dorsal hand lesions’ treatment responses were higher than finger lesions (p = 0.008 and 0.03, respectively). Upon evaluating adjuvant treatment modalities, all of the treatment regions receiving targeted UVB (n = 4) or topical 5-FU (n = 5) achieved the primary endpoint, whereas severe irritation limited the topical use of 5-FU. The most common adverse effects were mild oozing and crusting related to laser treatments. Conclusions: Even with high-energy settings, fractional erbium: YAG laser does not induce the Koebner phenomenon. Although controlled trials are required to make firm conclusions, fractional erbium: YAG laser was an effective and safe adjunctive option for stable vitiligo in a real-life setting.
