To examine the efficacy and safety of Narrowband ultraviolet B (NB-UVB) in Vietnamese vitiligo patients.
We recruited thirty-one patients (14 males, 17 females), aged from 7 to 67 years, with both segmental vitiligo (SV) and non-segmental vitiligo (NSV), treated three times weekly with NB-UVB. The starting dose for adults from 15 years old and children less than 15 years old was 200 mJ/cm and 150 mJ/cm, respectively, with 50 mJ/cm and 20 mJ/cm dose increments at each subsequent visit, respectively, until mild erythema lasting less than 24 hrs reported by patient, given for a period of 6 months. Response to therapy was assessed based on VASI score changes.
Based upon our results, 38.7% (12/31) of patients achieved a very good response of more than 50% VASI changes, 41.9% (13/31) obtained a good response (VASI changed from 25 to 50%). Total good and very good response to therapy significantly increased with prolonged treatment, increasing from 19.4% to 64.5% and 80.6% after 2, 4 and 6 months, respectively. Localised NSV patients obtained good and very good response significantly more frequently than generalised NSV (55.6% versus 18.2%). Adverse effects were minimal, of which one case developed herpes simplex, and 4 cases reported mild photo burn reaction which completely disappeared after adjusting the dose.
NB-UVB therapy is an effective and safe tool in the management of Vietnamese vitiligo patients.
探讨窄谱中波紫外线（NB-UVB）治疗越南白癜风患者的疗效和安全性。
我们招募了31例患者（14例男性，17例女性），年龄在7至67岁之间，患有节段性白癜风（SV）和非节段性白癜风（NSV），每周接受3次NB-UVB治疗。15岁及以上成人和15岁以下儿童的起始剂量分别为200 mJ/cm²和150 mJ/cm²，随后每次就诊剂量分别增加50 mJ/cm²和20 mJ/cm²，直至患者报告出现持续时间少于24小时的轻度红斑，治疗为期6个月。根据白癜风面积评分指数（VASI）变化评估治疗反应。
根据我们的结果，38.7%（12/31）的患者达到了VASI变化超过50%的非常好的反应，41.9%（13/31）的患者获得了良好的反应（VASI变化从25%至50%）。随着治疗时间的延长，治疗的总良好和非常好反应显著增加，在2、4和6个月后分别从19.4%增加到64.5%和80.6%。局限性NSV患者获得良好和非常好反应的频率明显高于泛发性NSV患者（55.6%对18.2%）。不良反应极少，其中1例发生单纯疱疹，4例报告有轻度光灼伤反应，调整剂量后完全消失。
NB-UVB疗法是治疗越南白癜风患者的一种有效且安全的方法。
