To assess the safety and efficacy of topical 0.1% tacrolimus vs 0.05% clobetasol propionate.
Randomized double-blind trial.
Department of Dermatology, Hospital Central Dr Ignacio Morones Prieto, San Luis Potosí, México.
From 20 children with vitiligo, 2 symmetrical lesions of about the same size and evolution time were selected. They were devoid of any topical or systemic therapy for 2 months prior to inclusion. Interventions Treatment with topical tacrolimus and clobetasol for a 2-month period.
The grade of repigmentation was evaluated by color slides at baseline and again at every 2-week visit. The slides were analyzed by 2 clinicians unrelated to the study and by a morphometric digitalized computer program. Characteristics of pigment, time of response, symptoms, telangiectasias, and atrophy were evaluated every 2 weeks.
Eighteen (90%) of the 20 patients experienced some repigmentation. The mean percentage of repigmentation was 49.3% for clobetasol and 41.3% for tacrolimus. Lesions in 3 patients using clobetasol presented atrophy, and 2 lesions incurred telangiectasias; tacrolimus caused a burning sensation in 2 lesions.
Tacrolimus proved almost as effective as clobetasol propionate to restore skin color in lesions of vitiligo in children. Because it does not produce atrophy or other adverse effects, tacrolimus may be very useful for younger patients and for sensitive areas of the skin such as eyelids, and it should be considered in other skin disorders currently treated with topical steroids for prolonged periods.
评估外用0.1%他克莫司与0.05%丙酸氯倍他索的安全性和有效性。
随机双盲试验。
墨西哥圣路易斯波托西市伊格纳西奥·莫罗内斯·普列托中央医院皮肤科。
从20名白癜风患儿中,选取2处大小和病程相近的对称皮损。入选前2个月内未接受任何局部或全身治疗。干预措施外用他克莫司和丙酸氯倍他索治疗2个月。
在基线时以及每2周复诊时通过彩色幻灯片评估色素沉着程度。由2名与研究无关的临床医生以及一个形态计量数字化计算机程序对幻灯片进行分析。每2周评估色素特征、反应时间、症状、毛细血管扩张和萎缩情况。
20例患者中有18例(90%)出现了一定程度的色素沉着。丙酸氯倍他索组的色素沉着平均百分比为49.3%,他克莫司组为41.3%。使用丙酸氯倍他索的3例患者的皮损出现萎缩,2处皮损出现毛细血管扩张;他克莫司导致2处皮损有烧灼感。
他克莫司在恢复儿童白癜风皮损肤色方面几乎与丙酸氯倍他索同样有效。由于它不会产生萎缩或其他不良反应,他克莫司可能对较年轻患者以及眼睑等皮肤敏感部位非常有用,并且在目前长期使用外用类固醇治疗的其他皮肤疾病中也应予以考虑。
