Phototherapy is the pillar of vitiligo treatment. One of its main obstacles is noncompliance. It was noticed that patients continue to repigment even after stopping sessions, so the idea of interrupted phototherapy emerged. To evaluate the effectiveness of interrupted versus continuous NB‐UVB in nonsegmental vitiligo treatment. A prospective randomized comparative study of 23 patients with bilateral, nonsegmental vitiligo with no age or sex limits. All patients were treated with NB‐UVB phototherapy for 1 month, after which one side of the body received continuous therapy (Side A) and the other received an interrupted course (Side B) for a total of 6 months. Two more groups of 10 patients were enrolled to exclude the systemic effect of NB‐UVB. One group received continuous NB‐UVB treatment, and the other received interrupted courses for 6 months. Evaluation of the results was performed clinically, by digital photography, planimetry and Vitiligo Area Scoring Index (VASI) prior to and 3 and 6 months after treatment. There was a significant clinical improvement in Group 1 compared to baseline (p < .05). However, there was no significant difference between the sides with regards to the clinical evaluation, point counting, and VASI scores (p > .05). When comparing the other two groups, there was a significant clinical improvement in each group after 6 months of treatment compared to baseline (p < .05), while there was no significant difference between them (p > .05). The current study suggests that interrupted NB‐UVB phototherapy is a good alternative to continuous treatment with improved patient compliance, fewer side effects, and a lower cost of treatment. 相似文献

Vitiligo on extremities and/or bony prominences is very resistant to treatment. Twenty‐five patients with symmetrical and stable vitiligo on extremities and/or bony prominences were enrolled. The treatment side received fractional carbon dioxide laser followed by topical compound betamethasone solution and narrowband ultraviolet B phototherapy. The control side received laser treatment plus phototherapy. The result of treatment side showed that 44% patients achieved over 50% re‐pigmentation and patient satisfaction score was 5.12 ± 3.23, higher than those of control (p < 0.05). Adverse events were slight and tolerable. The triple combination treatment could be used as an alternative modality for refractory vitiligo. 相似文献

Narrowband ultraviolet B (NB-UVB) phototherapy, with a 308-nm xenon chloride excimer laser, and targeted UVB phototherapy have produced encouraging therapeutic results for vitiligo. However, very few studies employing broadband UVB exist. Moreover, there has been no direct comparison study between broadband UVB and NB-UVB for the treatment of vitiligo. The aims of this study were to compare the repigmenting efficacy of targeted broadband UVB phototherapy with that of NB-UVB in an equi-erythemogenic manner. Twenty identical vitiliginous lesions from 10 patients were randomly allocated to receive either targeted broadband UVB or targeted NB-UVB phototherapy. UV fluences were started at 50% of the minimal erythema dose detected within the vitiliginous patches, then increased gradually, in the same manner, to ensure equi-erythemogenic comparison. Treatments were carried out twice weekly for 12 weeks. The results show that grade 1, i.e. 1-25% repigmentation, to grade 2, 26-50% repigmentation, occurred in 6 of 10 subjects. Responses in terms of repigmentation, de-pigmentation, or lack thereof, were similar between lesions receiving broadband and NB-UVB phototherapy. Onset of repigmentation occurred as early as 4 weeks of treatment in most subjects. Treatments were well tolerated, with only minimal erythema and hyperpigmentation. LIMITATIONS: The study was carried out in a small number of patients with skin types III, IV and V. The irradiation device was a targeted UVB device and thus the results may not be applicable to other light sources, such as the excimer laser or total-body irradiation cabinets. In conclusion, targeted broadband UVB produces similar clinical responses to targeted NB-UVB in the treatment of the non-segmental type of vitiligo. 相似文献

Background Non‐ablative 1550‐nm erbium‐doped fractional photothermolysis systems (FPS) and 10 600‐nm carbon dioxide fractional laser systems (CO2 FS) have been effectively used to treat scars. Objective We compared the efficacy and safety of single‐session treatments of FPS and CO2 FS for acne scars through a randomized, split‐face, evaluator‐blinded study. Methods Eight patients with acne scars were enrolled in this study. Half of each subject’s face was treated with FPS and the other half was treated with CO2 FS. We used a quartile grading scale for evaluations. Results At 3 months after the treatment, the mean grade of improvement based on clinical assessment was 2.0 ± 0.5 for FPS and 2.5 ± 0.8 for CO2 FS. On each side treated by FPS and CO2 FS, the mean duration of post‐therapy crusting and scaling was 2.3 and 7.4 days respectively and that of post‐therapy erythema was 7.5 and 11.5 days respectively. The mean VAS pain score was 3.9 ± 2.0 with the FPS and 7.0 ± 2.0 with the CO2 FS. Conclusion We demonstrated the efficacy and safety of single‐session acne scar treatment using FPS and CO2 FS in East Asian patients. We believe that our study could be used as an essential reference when choosing laser modalities for scar treatment. 相似文献

Background Pseudocatalase cream in conjunction with narrowband ultraviolet B (NB-UVB) has previously been reported to result in repigmentation of vitiliginous skin.
Objectives The purpose of this 24-week, double-blind, placebo-controlled, randomized, single-centre trial was to assess the efficacy of pseudocatalase cream and NB-UVB vs. placebo and NB-UVB for the treatment of vitiligo.
Methods Patients with active vitiligo on their face and/or hands applied either pseudocatalase cream or placebo to their whole body, twice daily for 24 weeks. NB-UVB therapy was administered three times a week for the duration of the trial. Efficacy was assessed primarily by digital image analysis of photographs.
Results Thirty-two patients were randomized to either the pseudocatalase arm ( n = 14) or placebo ( n = 18). Between-group analysis did not show a statistically significant improvement in percentage area affected in the pseudocatalase cream group when compared with placebo. However, a statistically significant improvement was found within each group by week 12, which was maintained throughout the study.
Conclusions NB-UVB treatment is a moderately effective treatment for vitiligo. Pseudocatalase cream does not appear to add any incremental benefit to NB-UVB alone. 相似文献

BACKGROUND: Vitiligo is a common pigmentary disorder with great cosmetic and psychological morbidity and an unpredictable course. No treatment available is a definitive cure. Systemic psoralen and ultraviolet A (PUVA) has been the mainstay of treatment. Narrow-band UVB (NBUVB) was later introduced. In this study, we have compared the phototherapy modalities PUVA and NBUVB in inducing stability in vitiligo, assessed by using vitiligo disease activity score (VIDA), for the first time. AIMS: To investigate the position of NBUVB vis-à-vis PUVA in terms of stability achieved during therapy as indicated by the VIDA scores. SUBJECTS AND METHODS: It was an open, prospective study of 50 patients divided equally in PUVA and NBUVB groups. The study period was from January 2004 to June 2005. This study was done as a part of a larger project to compare the efficacy of mentioned modalities in degree of repigmentation. RESULTS: In the NBUVB group, disease activity was present in 40% patients before commencement of therapy, which was reduced to 16% at the end of therapy (statistically significant, P = 0.049). In the PUVA group, similar figures were 20% and 16%, respectively. In the NBUVB group, 50% of patients whose disease was active prior to commencement of therapy had less than 50% repigmentation, whereas an equal number of patients had repigmentation of more than 50%. Almost an equal number of stable patients had less than and more than 50% repigmentation. In the PUVA group, 4 of the 5 (80%) patients who had active disease had less than 50% repigmentation, whereas only 1 patient (20%) with active disease obtained more than 50% repigmentation. The time to attain stability was 3.6 +/- 2.1 months in the NBUVB group and 3.22 +/- 3.1 months in the PUVA group. Eight of the 10 (80%) patients with unstable disease in the NBUVB group achieved stability, whereas 2 of the 5 (40%) patients of similar pre-treatment status in the PUVA group achieved stability. CONCLUSION: NBUVB was in a more statistically advantageous position vis-à-vis PUVA, in respect to stability achieved and efficacy in both active and stable disease in a comparable time period. 相似文献

Background The treatment of vitiligo remains unsatisfactory. Objectives To assess in patients with vitiligo the effect of a laser dermabrasion in addition to the association of topical steroids and ultraviolet (UV) B in difficult‐to‐treat areas. Methods This was a single‐centre prospective randomized trial including patients with nonsegmental vitiligo who had at least two symmetrical lesions located on bony prominences and/or extremities. An erbium laser‐assisted dermabrasion was first performed on one side (randomly assigned). After 48 h, hydrocortisone 17‐butyrate cream applied daily for three periods of 3 weeks followed by a 1‐week steroid‐free interval and narrowband UVB treatment was performed on both sides twice weekly for 12 weeks. The evaluation was performed on standardized pictures by two physicians blinded to the type of treatment received. The criterion of success was a repigmentation of at least 50%, 1 month after the end of the treatment. Results Eighteen patients were included (24 paired lesions treated). Two patients dropped out for personal reasons. Almost 50% of lesions achieved at least 50% repigmentation in the dermabrasion side while only 4·2% did so with topical steroids and UVB alone (P < 10?4). Side‐effects were delayed healing, pain and two hypertrophic scars. The tolerance and patient satisfaction were 4·2 and 4/10 for the laser‐treated side and 8·4 and 3/10 in the UVB+ steroids alone group, respectively. Conclusions Laser dermabrasion significantly improves the repigmentation rate in vitiligo lesions. Despite a high rate of repigmentation in such difficult‐to‐treat areas the high rate of side‐effects and the poor tolerance strongly limit its use in current practice. 相似文献

Conventional methods of treatment for vitiligo are often unsatisfactory to the patients and time consuming, new treatment modalities are needed. This study was conducted to evaluate the efficacy and safety of fractional carbon dioxide (CO2) laser therapy followed by narrow band ultraviolet‐B (NB‐UVB) phototherapy, topical tacrolimus or topical calcipotriol on stable nonsegmental vitiligo. Thirty patients with stable nonsegmental vitiligo were evaluated. All patients were subjected to three sessions of fractional CO2 laser 1 month apart. Patients were divided into three groups (each group 10 patients). Group (A) treated with tacrolimus ointment twice daily for 3 months, group (B) treated with calcipotriol ointment twice daily for 3 months, and group (C) treated with NB‐UVB twice weekly for 3 months. Outcomes were evaluated by calculating vitiligo area scoring index (VASI) score change, percentage of repigmentation, patient satisfaction, and adverse effects. There was a statistical significant decrease in VASI score after treatment in the three groups. The VASI change and % of regimentation was higher in group (C) treated by laser and NB‐UVB and this was significantly higher than group (B) treated with laser and calcipotriol. Otherwise, there was no statistical significant difference between other treatment groups. In concluion, NB‐UVB phototherapy, topical tacrolimus, or topical calcipotriol in combination with fractional CO2 laser could be used effectively and safely as an alternative modality for treatment of vitiligo. The combination of fractional CO2 laser and NB‐UVB was found to be more effective. 相似文献

Vitiligo is an acquired depigmenting disorder having disfiguring consequences. Many treatments have been attempted with varying reports of success. A parallel‐group, assessor blinded, randomized, controlled trial was designed to compare the efficacy and adverse effects of narrowband UVB (NBUVB) with oral psoralen UVA (PUVA) therapy in the treatment of vitiligo. Patients aged 13–70 years with vitiliginous lesions involving more than 5% body surface area were eligible for the study. In total, 56 patients were randomized in a 1 : 1 ratio to oral PUVA or NBUVB phototherapy groups. Patients were assessed for the percentage of repigmentation over the depigmented areas as the primary outcome measure at each visit during the first three months and then monthly within the next three months. The incidence of adverse effects was also noted during the study period as the secondary outcome measure. The median repigmentation achieved at the end of the six‐month therapy course was 45% in the NBUVB group and 40% in the oral PUVA group. Focal vitiligo had the best response in both treatment groups. There were lesser adverse effects within the NBUVB (7.4%) than in the PUVA (57.2%) group. Two PUVA patients discontinued therapy due to severe dizziness. There was no significant difference in the mean degree of repigmentation; however, NBUVB carried a greater response rate and might be superior to oral PUVA with better tolerance and color match with the surrounding normal skin, as well as fewer side effects in the treatment of vitiligo. 相似文献

Vitiligo is a difficult disease to treat, socially stigmatizing its patients. Monochromatic excimer light (MEL) was developed for use in dermatology and adapted for the treatment of vitiligo. Comparing the efficacy of MEL versus topical combination therapy of vitamin D3 analogue and steroid in the treatment of nonsegmental vitiligo. Forty‐four patients with localized and stable nonsegmental vitiligo participated in the present study. In each patient, two lesions were selected and divided randomly into two groups, group A was treated with daily topical combination of calcipotriol and betamethasone and group B was treated with biweekly sessions of MEL for 3 months. Efficacy based on repigmentation percentages were blindly evaluated by two independent physicians and patient's satisfaction. There was significant improvement in both treatment modalities at the end of the study, but without significant differences in both groups. There was a significant difference between both groups regarding the onset of repigmentation (p‐value < 0.05), whereas group B showed early sign of repigmentation in first 4 weeks of treatment in 16 patients versus 7 patients in group A. Both treatment modalities offered encouraging results and both are promising lines for the treatment of vitiligo. 相似文献
