The efficacy of pimecrolimus 1% cream plus narrow-band ultraviolet B in the treatment of vitiligo: a double-blind, placebo-controlled clinical trial

UVB phototherapy in the treatment of vitiligo: State of the art and clinical perspectives

Vitiligo is a chronic pigmentary skin disorder that results in white, hypopigmented macules and patches. It causes a considerable psychological and emotional burden on the affected individuals and their families. Several therapeutic options have been employed in vitiligo including topical and oral drugs, surgical techniques, and phototherapy which is considered the cornerstone treatment. Different wavelengths and modalities are available, but narrowband UVB (NB-UVB) is considered the safest and the most effective phototherapy alternative. NB-UVB acts on multiple steps in vitiligo pathogenesis, and it is capable of inducing stabilization and repigmentation of vitiligo lesions. Technological advances have led to the development of both new phototherapy devices and new medical and surgical therapeutic options that can be combined with phototherapy to achieve optimal results. There is no standard treatment, and individual patient and disease characteristics should be considered. We review the current evidence in what concerns UVB phototherapy for vitiligo treatment, including novel combination treatments that may help to provide the best care for these patients.

Combination of carboxytherapy with narrowband-ultraviolet B in the treatment of recalcitrant areas of vitiligo: A randomized clinical trial

Carboxytherapy has been used in the treatment of autoimmune skin diseases such as psoriasis and morphea. Carboxytherapy has antioxidant effects, and leads to better tissue oxygenation, and release of growth factors. In this article, we decided to evaluate efficacy of combined carboxytherapy and narrowband-ultraviolet B (NB-UVB) compared to NB-UVB alone in the treatment of vitiligo. This is a prospective, split-body double-blind comparative study performed in patients with generalized stable vitiligo in acral areas and extremities referred to dermatology clinic of Afzalipour hospital in Kerman University of Medical Sciences. NB-UVB was performed three times a week in non-consecutive days for 4 months. In each patient, one lesion was randomly treated with carboxytherapy (weekly sessions for total of 16 sessions). Efficacy of treatment was evaluated by percentage of repigmentation of the lesions. Chi-square test and analysis of variance test (ANOVA) were used to compare efficacy of treatment based on demographic features of the patients and clinical features of the lesions, respectively. Twenty-eight patients with mean age of 32.35 ± 7.37 years old completed the study. At the end of the treatment, 37% of the patients in combination therapy group demonstrated more than 75% improvement compared to 0% in the monotherapy group (p = 0.001). There was no significant difference between either demographic features of the patients (age, sex, and skin phototypes) or duration of disease with efficacy of the treatment in both groups. Combination of carboxytherapy with NB-UVB leads to higher percentage of repigmentation and patients' satisfaction compared to monotherapy with NB-UVB.

The scope of health insurance coverage of vitiligo treatments in the United States: Implications for health care outcomes and disparities in children of color

BACKGROUND

Patients of color are disproportionately impacted by vitiligo. Access to treatment depends greatly on insurance coverage. We, therefore, assessed current vitiligo treatment coverage policies across major United States health insurers to determine current patterns and coverage gaps for vitiligo.

METHODS

The study surveyed 15 commercial health care insurers, 50 BlueCross BlueShield (BCBS) plans, Medicare, Medicaid, and Veterans Affairs. Information on treatment coverage for vitiligo, specifically pimecrolimus and tacrolimus, excimer laser therapy, PUVA, and narrow-band (nb)UVB, was collected via an online review of insurance policy documents, confirmed with phone calls to organization representatives, or via a survey of Medicaid providers, and state Medicaid directors.

RESULTS

Of 17 organizations with regional or national coverage policies, 12% did not cover topical calcineurin inhibitors, 56% did not cover nbUVB phototherapy, 53% did not cover PUVA phototherapy, and 41% did not cover laser therapy. For BCBS, pimecrolimus and tacrolimus were not covered in 39% and 35% of states, respectively. NbUVB and PUVA therapy were not covered in 20% and 10% of states, respectively. Excimer laser therapy was not covered in 82% of states. Out of 32 states with accessible Medicaid information, 11 did not cover topicals, 5 did not cover nbUVB, 4 did not cover PUVA, and 7 did not cover laser. Two commonly cited reasons for coverage denial were that the treatment indication was considered cosmetic, and certain therapies are not FDA-approved.

CONCLUSIONS

There is inequity in the distribution of health among vitiligo patients given current patterns of insurance coverage for treatment, which may have disproportionate impact on patients of color.

Vitiligo Skin Biomarkers Associated With Favorable Therapeutic Response

Vitiligo is an acquired depigmentation skin disease caused by immune-mediated death of melanocytes. The most common treatment for vitiligo is narrow band ultraviolet B phototherapy, which often is combined with topical therapies such as tacrolimus. However, patients' responses to these treatments show large variations. To date, the mechanism for this heterogeneity is unknown, and there are no molecular indicators that can predict an individual patient's response to therapy. The goal of this study is to identify clinical parameters and gene expression biomarkers associated with vitiligo response to therapy. Six patients with segmental vitiligo and 30 patients with non-segmental vitiligo underwent transcriptome sequencing of lesional and nonlesional skin at baseline before receiving combined UBUVB and tacrolimus therapy for 6 month, and were separated into good response and bad response groups based on target lesion achieving > 10% repigmentation or not. Our study revealed that treatment-responsive vitiligo lesions had significantly shorter disease duration compared with non-responsive vitiligo lesions (2.5 years vs 11.5 years, p=0.046, t-Test), while showing no significant differences in the age, gender, ethnicity, vitiligo subtype, or disease severity. Transcriptomic analyses identified a panel of 68 genes separating the good response from bad response lesions including upregulation of immune active genes, such as CXCL10, FCRL3, and TCR, Further, compared with vitiligo lesions with long disease duration, the lesions with short duration also have much higher level of expression of immune-active genes, including some (such as FCRL3 and TCR genes) that are associated with favorable therapeutic response. In conclusion, our study has identified clinical parameters such as short disease duration and a panel of immune active and other gene expression biomarkers that are associated with favorable response to immune suppressive NBUVB + tacrolimus therapy. These markers may be useful clinically for individualized therapeutic management of vitiligo patients in the future.

A comparative study on the use of fractional CO2 laser with tacrolimus or calcipotriol or narrow band ultraviolet-B in treatment of stable nonsegmental vitiligo

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.

Consensus on the treatment of vitiligo - Brazilian Society of Dermatology

Background

Vitiligo is a muco-cutaneous, autoimmune, localized, or disseminated disease, which manifests through hypochromic or achromic macules, with loss in quality of life. The prevalence of vitiligo in Brazil was determined to be 0.54%. There is no on-label medication for its treatment. To date, no Brazilian consensus on the treatment of vitiligo had been written.

Objectives

The objective of this group of Brazilian dermatologists with experience in the treatment of this disease was to reach a consensus on the clinical and surgical treatment of vitiligo, based on articles with the best scientific evidence.

Methods

Seven dermatologists were invited, and each was assigned two treatment modalities to review. Each treatment (topical, systemic, and phototherapy) was reviewed by three experts. Two experts reviewed the surgical treatment. Subsequently, the coordinator compiled the different versions and drafted a text about each type of treatment. The new version was returned to all experts, who expressed their opinions and made suggestions for clarity. The final text was written by the coordinator and sent to all participants to prepare the final consensus.

Results/Conclusion

The experts defined the following as standard treatments of vitiligo: the use of topical corticosteroids and calcineurin inhibitors for localized and unstable cases; corticosteroid minipulse in progressive generalized vitiligo; narrowband UVB phototherapy for extensive forms of the disease. Surgical modalities should be indicated for segmental and stable generalized vitiligo. Topical and systemic anti-JAK drugs are being tested, with promising results.

Recent Progress and Future Directions: The Nano-Drug Delivery System for the Treatment of Vitiligo

Vitiligo is a depigmentation disease that seriously affects the physical health, mental health and quality of life of a patient. Therapeutic aim at control immunoreaction by relieving oxidative stress. Unfortunately, the cuticle barrier function and lack of specific accumulation lead to unsatisfactory therapeutic outcomes and side effects. The introduction and innovation of nanotechnology offers inspiration and clues for the development of new strategies to treat vitiligo. However, not many studies have been done to interrogate how nanotechnology can be used for vitiligo treatment. In this review, we summarize and analyze recent studies involving nano-drug delivery systems for the treatment of vitiligo, with a special emphasis on liposomes, niosomes, nanohydrogel and nanoparticles. These studies made significant progress by either increasing drug loading efficiency or enhancing penetration. Based on these studies, there are three proposed principles for topical nano-drug delivery systems treatment of vitiligo including the promotion of transdermal penetration, enhancement of drug retention and facilitation of melanin regeneration. The presentation of these ideas may provide inspirations for the future development of topical drug delivery systems that will conquer vitiligo.

Phototherapy for Vitiligo

Vitiligo is a common disorder with a severe impact on quality of life. The authors review recent advances in phototherapy for vitiligo focusing on narrowband ultraviolet B including mechanisms, treatment recommendations, and combination therapies. Phototherapy is the first-line treatment of choice for vitiligo with narrowband UVB preferred for widespread vitiligo and excimer used for localized lesions. However, unfamiliarity with prescribing phototherapy may be limiting clinicians from using it to its full potential. This article provides clinicians with the critical information needed to safely and effectively provide phototherapy for their patients with vitiligo.

Childhood Vitiligo

Vitiligo is a common acquired depigmenting skin disease characterized by a progressive loss of functional melanocytes. It may appear from the first years of life to late adulthood. Childhood vitiligo (CV), defined as vitiligo that begins before the age of 12 years, is common and may differ from post-CV in terms of epidemiology, clinical presentation, comorbidities, and treatment options. Taking into consideration the potential significant psychosocial impact of the disease on both children and their parents, all available therapeutic options must be offered to patients who desire treatment. According to the most recent guidelines, topical corticosteroids, topical calcineurin inhibitors, and narrowband ultraviolet B phototherapy are the most commonly used treatment modalities for vitiligo in children. This review presents recent data regarding the whole spectrum of CV. Differences between CV and post-CV are also discussed.

Treatment Outcomes of Topical Calcineurin Inhibitor Therapy for Patients With Vitiligo: A Systematic Review and Meta-analysis

Importance

Topical calcineurin inhibitors (TCIs), including tacrolimus and pimecrolimus, have been widely used for the treatment of vitiligo; however, the efficacy of TCI monotherapy is often underestimated.

Objectives

To estimate the treatment responses to both TCI monotherapy and TCI accompanied by phototherapy for vitiligo, based on relevant prospective studies, and to systematically review the mechanism of action of TCIs for vitiligo treatment.

Data Sources

A comprehensive search of the MEDLINE, Embase, Web of Science and Cochrane Library databases from the date of database inception to August 6, 2018, was conducted. The main key words used were vitiligo, topical calcineurin inhibitor, tacrolimus, pimecrolimus, and FK506.

Study Selection

Of 250 studies initially identified, the full texts of 102 articles were assessed for eligibility. A total of 56 studies were identified: 11 studies on the TCI mechanism, 36 studies on TCI monotherapy, 12 studies on TCI plus phototherapy, and 1 study on TCI maintenance therapy.

Data Extraction and Synthesis

Two reviewers independently extracted data on study design, patients, intervention characteristics, and outcomes. Random-effects meta-analyses using the generic inverse variance weighting were performed for the TCI monotherapy and TCI plus phototherapy groups.

Main Outcomes and Measures

The primary outcomes were the rates of at least mild (≥25%), at least moderate (≥50%), and marked (≥75%) repigmentation responses to treatment. These rates were calculated by dividing the number of participants in an individual study who showed the corresponding repigmentation by the total number of participants who completed that study.

Results

In the 56 studies included in the analysis, 46 (1499 patients) were selected to evaluate treatment response. For TCI monotherapy, an at least mild response was achieved in 55.0% (95% CI, 42.2%-67.8%) of 560 patients in 21 studies, an at least moderate response in 38.5% (95% CI, 28.2%-48.8%) of 619 patients in 23 studies, and a marked response in 18.1% (95% CI, 13.2%-23.1%) of 520 patients in 19 studies after median treatment duration of 3 months (range, 2-7 months). In the subgroup analyses, face and neck lesions showed an at least mild response in 73.1% (95% CI, 32.6-83.5%) of patients, and a marked response in 35.4% (95% CI, 24.9-46.0%) of patients. For TCI plus phototherapy, an at least mild response to TCI plus phototherapy was achieved in 89.5% (95% CI, 81.1-97.9%) of patients, and a marked response was achieved in 47.5% (95% CI, 30.6-64.4%) of patients.

Conclusions and Relevance

The use of TCIs, both as a monotherapy and in combination with phototherapy, should be encouraged in patients with vitiligo.

Off-label Uses of Topical Pimecrolimus

Pimecrolimus is a topical calcineurin inhibitor currently approved for second-line use in the management of mild-to-moderate atopic dermatitis in patients age 2 years and older. Given the safety profile and nonsteroidal mechanism of pimecrolimus, there has been significant interest in its use in the treatment of a variety of dermatological conditions. This article reviews research that has been published on the off-label uses of topical pimecrolimus, with a focus on published RCTs. Convincing evidence exists supporting pimecrolimus' efficacy in oral lichen planus and seborrheic dermatitis. For other conditions studied to date, pimecrolimus may prove to be a useful treatment alternative when conventional agents fail. Adverse events seen with its off-label use were typically application site reactions, the most common being a transient burning sensation. In summary, pimecrolimus appears to be an effective agent in the treatment of multiple dermatological conditions and may be worth considering as a pharmacologic alternative in several conditions when first-line treatment fails, or for areas that are more susceptible to the adverse effects of topical corticosteroids.

Vitiligo-like lesions occurring in patients receiving anti-programmed cell death-1 therapies

Antibody-based therapeutics targeting programmed cell death 1 (PD-1) have shown strong efficacy in the treatment of metastatic cancers as melanoma. However, restoring the immune function with these therapies to target cancer cells leads to immune side effects including immune cutaneous events. Vitiligo-like lesions in patients receiving anti-PD-1 is one of the most common skin adverse event reported and the incidence seems to be higher than in patients receiving other immune-checkpoints therapies. Initially described in patients with metastatic melanoma, vitiligo-like lesions have now been reported in other metastatic cancers treated with anti-PD-1. Several reports suggest that this side effect could be different from spontaneously occurring vitiligo and could be associated with increased response to the therapy and patients' survival. The aim of this review is to provide an overview of the clinical presentation of vitiligo-like lesions occurring in patients receiving anti-PD-1, and the hypothesis to explain the mechanism involved in the development of these lesions.

Phototherapy and Combination Therapies for Vitiligo

Vitiligo is a disease characterized by disappearance of melanocytes from the skin. It can negatively influence the physical appearance of affected individuals, and may profoundly affect a person's psychosocial function and quality of life. Therefore, vitiligo should not be considered as merely a condition that affects a patient's appearance, but needs to be actively treated in patients who seek medical help. Phototherapy has been used as the main treatment modality for patients with vitiligo. Different forms of phototherapy for vitiligo include broadband UVB, narrowband UVB, excimer light and excimer laser, and psoralen plus UVA.

Effect of combination of fractional CO2 laser and narrow-band ultraviolet B versus narrow-band ultraviolet B in the treatment of non-segmental vitiligo

The present study was designed to evaluate the effect of combining fractional CO₂ laser with narrow-band ultraviolet B (NB-UVB) versus NB-UVB in the treatment of non-segmental vitiligo. The study included 20 patients with non-segmental stable vitiligo. They were divided into two groups. Group I received a single session of fractional CO₂ laser therapy on the right side of the body followed by NB-UVB phototherapy twice per week for 8 weeks. Group II received a second session of fractional CO₂ laser therapy after 4 weeks from starting treatment with NB-UVB. The vitiligo lesions were assessed before treatment and after 8 weeks of treatment by VASI. At the end of the study period, the vitiligo area score index (VASI) in group I decreased insignificantly on both the right (-2.6%) and left (-16.4%) sides. In group II, VASI increased insignificantly on the right (+14.4%) and left (+2.5%) sides. Using Adobe Photoshop CS6 extended program to measure the area of vitiligo lesions, group I showed a decrease of -1.02 and -6.12% in the mean area percentage change of vitiligo lesions on the right and left sides, respectively. In group II the change was +9.84 and +9.13% on the right and left sides, respectively. In conclusion, combining fractional CO₂ laser with NB-UVB for the treatment of non-segmental vitiligo did not show any significant advantage over treatment with NB-UVB alone. Further study of this combination for longer durations in the treatment of vitiligo is recommended.

Phototherapy for Vitiligo: A Systematic Review and Meta-analysis

Importance

References to the expected treatment response to phototherapy would be helpful in the management of vitiligo because phototherapy requires long treatment durations over several months.

Objective

To estimate the treatment response of vitiligo to phototherapy.

Data Sources

A comprehensive database search of MEDLINE, EMBASE, and the Cochrane library from inception to January 26, 2016, was performed for all prospective studies. The main keywords used were vitiligo, phototherapy, psoralen, PUVA, ultraviolet, NBUVB, and narrowband.

Study Selection

All prospective studies reporting phototherapy outcome for at least 10 participants with generalized vitiligo were included. Of 319 studies initially identified, the full texts of 141 studies were assessed for eligibility, and 35 were finally included in the analysis. Of these, 29 studies included 1201 patients undergoing narrowband UV-B (NBUVB) phototherapy, and 9 included 227 patients undergoing psoralen-UV-A (PUVA) phototherapy.

Data Extraction and Synthesis

Two reviewers independently extracted the following data: study design, number and characteristics of the participants, phototherapy protocol, and rate of repigmentation based on the quartile scale. Single-arm meta-analyses were performed for the NBUVB and PUVA groups. Sample size-weighted means were calculated using a random-effects model for the repigmentation rates of the included studies.

Main Outcomes and Measures

The primary outcomes were at least mild (≥25%), at least moderate (≥50%), and marked (≥75%) responses on a quartile scale. Response rates were calculated as the number of participants who showed the corresponding repigmentation divided by the number of all participants enrolled in the individual studies.

Results

The meta-analysis included 35 unique studies (1428 unique patients). For NBUVB phototherapy, an at least mild response occurred in 62.1% (95% CI, 46.9%-77.3%) of 130 patients in 3 studies at 3 months, 74.2% (95% CI, 68.5%-79.8%) of 232 patients in 11 studies at 6 months, and 75.0% (95% CI, 60.9%-89.2%) of 512 patients in 8 studies at 12 months. A marked response was achieved in 13.0% (95% CI, 2.1%-23.9%) of 106 patients in 2 studies at 3 months, 19.2% (95% CI, 11.4%-27.0%) of 266 patients in 13 studies at 6 months, and 35.7% (95% CI, 21.5%-49.9%) of 540 patients in 9 studies at 12 months. For PUVA phototherapy, an at least mild response occurred in 51.4% (95% CI, 28.1%-74.7%) of 103 patients in 4 studies at 6 months and 61.6% (95% CI, 20.2%-100%) of 72 patients in 3 studies at 12 months. In the subgroup analyses, marked responses were achieved on the face and neck in 44.2% (95% CI, 24.2%-64.2%), on the trunk in 26.1% (95% CI, 8.7%-43.5%), on the extremities in 17.3% (95% CI, 8.2%-26.5%), and on the hands and feet in none after at least 6 months of NBUVB phototherapy.

Conclusions and Relevance

Long-duration phototherapy should be encouraged to enhance the treatment response in vitiligo. The greatest response is anticipated on the face and neck.

A programme of research to set priorities and reduce uncertainties for the prevention and treatment of skin disease

Background

Skin diseases are very common and can have a large impact on the quality of life of patients and caregivers. This programme addressed four diseases: (1) eczema, (2) vitiligo, (3) squamous cell skin cancer (SCC) and (4) pyoderma gangrenosum (PG).

Objective

To set priorities and reduce uncertainties for the treatment and prevention of skin disease in our four chosen diseases.

Design

Mixed methods including eight systematic reviews, three prioritisation exercises, two pilot randomised controlled trials (RCTs), three feasibility studies, two core outcome initiatives, four funding proposals for national RCTs and one completed national RCT.

Setting

Secondary care, primary care and the general population.

Participants

Patients (and their caregivers) with eczema, vitiligo, SCC and PG, plus health-care professionals with an interest in skin disease.

Interventions

Our three intervention studies included (1) barrier enhancement using emollients from birth to prevent eczema (pilot RCT); (2) handheld narrowband ultraviolet light B therapy for treating vitiligo (pilot RCT); and (3) oral ciclosporin (Neoral®, Novartis Pharmaceuticals) compared with oral prednisolone for managing PG (pragmatic national RCT).

Results

Systematic reviews included two overarching systematic reviews of RCTs of treatments for eczema and vitiligo, an umbrella review of systematic reviews of interventions for the prevention of eczema, two reviews of treatments for SCC (one included RCTs and the second included observational studies), and three reviews of outcome measures and outcome reporting. Three prioritisation partnership exercises identified 26 priority areas for future research in eczema, vitiligo and SCC. Two international consensus initiatives identified four core domains for future eczema trials and seven core domains for vitiligo trials. Two pilot RCTs and three feasibility studies critically informed development of four trial proposals for external funding, three of which are now funded and one is pending consideration by funders. Our pragmatic RCT tested the two commonly used systemic treatments for PG (prednisolone vs. ciclosporin) and found no difference in their clinical effectiveness or cost-effectiveness. Both drugs showed limited benefit. Only half of the participants’ ulcers had healed by 6 months. For those with healed ulcers, recurrence was common (30%). Different side effect profiles were noted for each drug, which can inform clinical decisions on an individual patient basis. Three researchers were trained to PhD level and a dermatology patient panel was established to ensure patient involvement in all aspects of the programme.

Conclusions

Findings from this programme of work have already informed clinical guidelines and patient information resources. Feasibility studies have ensured that large national pragmatic trials will now be conducted on important areas of treatment uncertainty that address the needs of patients and the NHS. There is scope for considerable improvement in terms of trial design, conduct and reporting for RCTs of skin disease, which can be improved through wider collaboration, registration of trial protocols and complete reporting and international consensus over core outcome sets. Three national trials have now been funded as a result of this work. Two international initiatives to establish how best to measure the core outcome domains for eczema and vitiligo are ongoing.

Effect of narrow band ultraviolet B phototherapy as monotherapy or combination therapy for vitiligo: a meta-analysis

BACKGROUND

The treatment of vitiligo is still one of the most difficult dermatological challenges, although there are many therapeutic options. Narrow band ultraviolet B (NB-UVB) phototherapy is considered to be a very important modality for generalized vitiligo.

OBJECTIVE

The aim of this study was to explore whether a combination of NB-UVB and topical agents would be superior to NB-UVB alone for treating vitiligo.

METHODS

We searched the electronic databases such as PUBMED, EMBASE, Cochrane Library, and Web of Science. The primary outcome was the proportion of ≥50% repigmentation (a clinical significance), and secondary outcome was the proportion of ≥75% repigmentation (an excellent response).

RESULTS

Seven randomized controlled trials (RCTs) involving 240 patients (413 lesions) were included in this meta-analysis. The study showed no significant difference between NB-UVB combination therapy (NB-UVB and topical calcineurin inhibitor or vitamin D analogs) and NB-UVB monotherapy in the outcomes of ≥50% repigmentation and ≥75% repigmentation. However, lesions located on the face and neck had better results in ≥50% repigmentation (RR = 1.40, 95% CI 1.08-1.81) and ≥75% repigmentation (RR = 1.88, 95% CI 1.10-3.20) with NB-UVB and topical calcineurin inhibitor combination therapy vs. NB-UVB monotherapy.

CONCLUSIONS

The meta-analysis suggested that adding neither topical calcineurin inhibitors nor topical vitamin-D3 analogs on NB-UVB can yield significantly superior outcomes than NB-UVB monotherapy for treatment of vitiligo. However, addition of topical calcineurin inhibitors to NB-UVB may increase treatment outcomes in vitiligo affecting face and neck.

The Safety and Efficacy of Narrow Band Ultraviolet B Treatment in Dermatology: A Review

Narrow-band ultraviolet B (NBUVB) phototherapy is an important treatment modality in dermatology. The most common dermatological indications for NBUVB include psoriasis, atopic dermatitis and vitiligo; however, it has been found to be an effective and well-tolerated treatment option in various other dermatoses. The efficacy of NBUVB phototherapy compares favorably with other available photo(chemo)therapy options and its efficacy is further augmented by a number of topical and systemic adjuncts. The long-term safety of NBUVB phototherapy remains to be fully elucidated; however, available data now suggest that it is safe and well-tolerated. The objective of this review was to summarize the current understanding of the safety and efficacy of NBUVB phototherapy in dermatology.

Current Management of Pediatric Vitiligo

Vitiligo is a common inflammatory disorder with worldwide prevalence of 0.4-2 % of the population, with half of cases beginning in childhood. The management of childhood vitiligo should be tailored to avoid negative effects on the overall growth and psychological development of the patient. Therapy of vitiligo in childhood is chosen based on the location of the lesions, lesion age, and extent of lesions in the context of the child's age and the developmental status of the child. There are four age categories in childhood vitiligo: [1] infantile and toddler (rare) (ages 0-3 years), [2] ages 4-8 years, [3] ages 9-12 years, and [4] 13+ years of age, based on developmental stage, psychological maturation, and ability to comply or participate in therapy. These categories are also differentiated psychologically by susceptibility to bullying, self-image development, and personal concern with lesion appearance, which increases with time. Intervention is advisable in cases with facial and leg involvement due to prominence of lesions and cosmetic defect. Medical interventions are largely the usage of topical therapies including corticosteroids and calcineurin inhibitors, some vitamin therapy (oral and topical vitamin D), and judicious introduction of phototherapy sources based on age and severity. Screening and appropriate subspecialist referral for co-morbidities (e.g., thyroid disease, celiac disease, psychological distress, and vitamin D deficiency) may enhance overall health. Cosmesis and camouflage are generally safe in childhood and have been noted to improve overall quality of life in this grouping. Genetic transmission of vitiligo is minimal at 5-6 % in first-degree relatives. This article reviews the therapeutics of pediatric vitiligo from the perspective of developmental stages and response to therapy.

Effects of a preceding fractional carbon dioxide laser on the outcome of combined local narrowband ultraviolet B and topical steroids in patients with vitiligo in difficult-to-treat areas

BACKGROUND AND OBJECTIVE

Conventional treatment of vitiligo on hands and feet often produces an unsatisfactory result. Various ablative treatment methods were tried with favorable results in facial, neck, and truncal areas. The aim of this study is to evaluate the efficacy and safety of combined fractional CO2 laser, narrowband UVB (NB-UVB) phototherapy, and topical clobetasol propionate in managing stable vitiligo in difficult-to-treat areas.

STUDY DESIGN

A prospective randomized-intraindividual study was conducted on 27 patients with 27 pair-lesions of non-segmental vitiligo on both hands. The lesions were randomized to receive treatment with fractional CO2 laser, NB-UVB phototherapy, and 0.05% clobetasol propionate cream (Group A) or NB-UVB phototherapy and 0.05% clobetasol propionate cream (Group B). Fractional CO2 laser was performed at 1-week interval for 10 sessions. NB-UVB phototherapy was administered twice weekly for 20 sessions. Patients were evaluated 12 weeks after the last treatment. Outcome was evaluated objectively based on standard digital photographs, patient satisfaction, and adverse events.

RESULTS

Twenty-six patients completed the study. Six vitiligious lesions (23.1%) in group A achieved good to excellent repigmentation compared with one lesion (3.9%) in group B (P = 0.065). The overall mean improvement score was 1.35 (± 1.38) in group A and 0.50 (± 0.95) in group B (P = 0.0004). Patients' satisfaction score was significantly higher for the lesions in group A than group B. Lesions on the dorsum of the hand showed a higher response rate than those on the fingers. No serious side-effects were noted.

CONCLUSION

This study demonstrates that adding fractional CO2 laser treatment to NB-UVB phototherapy and topical steroids improves the repigmentation rate of vitiliginous lesions on hands in some patients. This technique may be offered to vitiligo patients who are unresponsive to other treatments.

Phototherapy for the treatment of vitiligo in Asian children

Vitiligo is a common acquired progressive depigmenting condition that can have devastating psychological effects in dark-skinned patients. We performed a retrospective review of patients younger than 16 years of age with a clinical diagnosis of vitiligo treated using phototherapy at the National Skin Center, Singapore, over a 5-year period. Seventy-one Asian patients ages 5 to 15 years when they underwent phototherapy were identified. There was a higher proportion of Indian patients in our cohort than in the population. The duration of disease ranged from 2 months to 12 years. More than half of the patients had generalized vitiligo and more than one-third had segmental vitiligo. Patients with generalized vitiligo had a better response than those with segmental vitiligo. Reported response rates were highest for narrowband ultraviolet B (UVB) phototherapy, followed by targeted phototherapy combining ultraviolet A1 (UVA1) and UVB; 308-nm excimer lamp phototherapy and paint psoralen-UVA photochemotherapy had marginally lower reported response rates. The duration of treatment ranged from 3 to 40 months and the total number of treatments ranged from 20 to 209 sessions. Reported side effects were mild and included itching, scaling, erythema, pain, sunburn, blistering, and phototoxicity. We consider phototherapy to be a safe and efficacious modality for the treatment of vitiligo in Asian children.

Interventions for vitiligo

BACKGROUND

Vitiligo is a chronic skin disorder characterised by patchy loss of skin colour. Some people experience itching before the appearance of a new patch. It affects people of any age or ethnicity, more than half of whom develop it before the age of 20 years. There are two main types: generalised vitiligo, the common symmetrical form, and segmental, affecting only one side of the body. Around 1% of the world's population has vitiligo, a disease causing white patches on the skin. Several treatments are available. Some can restore pigment but none can cure the disease.

OBJECTIVES

To assess the effects of all therapeutic interventions used in the management of vitiligo.

SEARCH METHODS

We updated our searches of the following databases to October 2013: the Cochrane Skin Group Specialised Register, CENTRAL in The Cochrane Library (2013, Issue 10), MEDLINE, Embase, AMED, PsycINFO, CINAHL and LILACS. We also searched five trials databases, and checked the reference lists of included studies for further references to relevant randomised controlled trials (RCTs).

SELECTION CRITERIA

Randomised controlled trials (RCTs) assessing the effects of treatments for vitiligo.

DATA COLLECTION AND ANALYSIS

At least two review authors independently assessed study eligibility and methodological quality, and extracted data.

MAIN RESULTS

This update of the 2010 review includes 96 studies, 57 from the previous update and 39 new studies, totalling 4512 participants. Most of the studies, covering a wide range of interventions, had fewer than 50 participants. All of the studies assessed repigmentation, however only five reported on all of our three primary outcomes which were quality of life, > 75% repigmentation and adverse effects. Of our secondary outcomes, six studies measured cessation of spread but none assessed long-term permanence of repigmentation resulting from treatment at two years follow-up.Most of the studies assessed combination therapies which generally reported better results. New interventions include seven new surgical interventions.We analysed the data from 25 studies which assessed our primary outcomes. We used the effect measures risk ratio (RR), and odds ratio (OR) with their 95% confidence intervals (CI) and where N is the number of participants in the study.We were only able to analyse one of nine studies assessing quality of life and this showed no statistically significant improvement between the comparators.Nine analyses from eight studies reported >75% repigmentation. In the following studies the repigmentation was better in the combination therapy group: calcipotriol plus PUVA (psoralen with UVA light) versus PUVA (paired OR 4.25, 95% CI 1.43 to 12.64, one study, N = 27); hydrocortisone-17-butyrate plus excimer laser versus excimer laser alone (RR 2.57, 95% CI 1.20 to 5.50, one study, N = 84); oral minipulse of prednisolone (OMP) plus NB-UVB (narrowband UVB) versus OMP alone (RR 7.41, 95% CI 1.03 to 53.26, one study, N = 47); azathioprine with PUVA versus PUVA alone (RR 17.77, 95% CI 1.08 to 291.82, one study, N = 58) and 8-Methoxypsoralen (8-MOP ) plus sunlight versus psoralen (RR 2.50, 95% CI 1.06 to 5.91, one study, N = 168). In these three studies ginkgo biloba was better than placebo (RR 4.40, 95% CI 1.08 to 17.95, one study, N = 47); clobetasol propionate was better than PUVAsol (PUVA with sunlight) (RR 4.70, 95% CI 1.14 to 19.39, one study, N = 45); split skin grafts with PUVAsol was better than minipunch grafts with PUVAsol (RR 1.89, 95% CI 1.25 to 2.85, one study, N = 64).We performed one meta-analysis of three studies, in which we found a non-significant 60% increase in the proportion of participants achieving >75% repigmentation in favour of NB-UVB compared to PUVA (RR 1.60, 95% CI 0.74 to 3.45; I² = 0%).Studies assessing topical preparations, in particular topical corticosteroids, reported most adverse effects. However, in combination studies it was difficult to ascertain which treatment caused these effects. We performed two analyses from a pooled analysis of three studies on adverse effects. Where NB-UVB was compared to PUVA, the NB-UVB group reported less observations of nausea in three studies (RR 0.13, 95% CI 0.02 to 0.69; I² = 0% three studies, N = 156) and erythema in two studies (RR 0.73, 95% CI 0.55 to 0.98; I² = 0%, two studies, N = 106), but not itching in two studies (RR 0.57, 95% CI 0.20 to 1.60; I² = 0%, two studies, N = 106).Very few studies only assessed children or included segmental vitiligo. We found one study of psychological interventions but we could not include the outcomes in our statistical analyses. We found no studies evaluating micropigmentation, depigmentation, or cosmetic camouflage.

AUTHORS' CONCLUSIONS

This review has found some evidence from individual studies to support existing therapies for vitiligo, but the usefulness of the findings is limited by the different designs and outcome measurements and lack of quality of life measures. There is a need for follow-up studies to assess permanence of repigmentation as well as high- quality randomised trials using standardised measures and which also address quality of life.

Vitiligo: an evidence-based update. Report of the 13th Evidence Based Update Meeting, 23 May 2013, Loughborough, U.K

The Evidence Based Update (EBU) meetings are annual one-day meetings held by the Centre of Evidence Based Dermatology at the University of Nottingham. The aim of the meeting is to discuss high-quality evidence, mainly in the form of systematic reviews and randomized controlled trials, on a different topic each year. The meetings are designed to be interactive with a panel discussion between international experts and delegates forming a key part of the meeting. The 13th EBU meeting was on vitiligo and took place on 23 May 2013 in Loughborough, U.K. The most recent research including new and unpublished studies was presented on the classification of vitiligo, the evidence behind different treatment options and current guidelines for vitiligo.

Efficacy of targeted narrowband ultraviolet B therapy in vitiligo

BACKGROUND

Phototherapy is one of the most effective treatment options in vitiligo. Targeted phototherapy devices are becoming more popular as they offer a lot of advantages over the conventional whole-body phototherapy units.

AIMS AND OBJECTIVES

The present study was conducted to assess the efficacy and safety of a targeted narrowband ultraviolet B (NBUVB) device in vitiligo.

MATERIALS AND METHODS

A total of 40 patients of vitiligo were treated with a targeted NBUVB device twice-weekly for a maximum of 30 sessions or until 100% repigmentation, whichever was reached first. The extent of repigmentation achieved was assessed and adverse effects, if any, were also noted down.

RESULTS

There were 31 responders (77.5%) who achieved repigmentation ranging from 50% to 100%. The onset of repigmentation was seen as early as the 3(rd) dose in some cases and by the 10(th) dose in all responders. A total of 97 lesions were treated out of which 45 lesions (46.6%) achieved 90-100% repigmentation. Lesions showing 75% and 50% repigmentation were 14 and 15 in number respectively. 23 lesions failed to show any significant repigmentation at the end of 30 doses. Best response was seen on the face and neck with 20 of the 31 lesions achieving 90-100% repigmentation in this area. Duration of vitiligo was seen to have no statistically significant impact on the repigmentation achieved.

CONCLUSION

Targeted NBUVB phototherapy seems to be an effective treatment option in localized vitiligo with a rapid onset of repigmentation seen as early as 2(nd) week of treatment.

Which outcomes should we measure in vitiligo? Results of a systematic review and a survey among patients and clinicians on outcomes in vitiligo trials

BACKGROUND

Relevant and reliable outcomes play a crucial role in the correct interpretation and comparison of the results of clinical trials. There is a lack of consensus around methods of assessment and outcome measures for vitiligo, which makes it difficult to compare results of randomized controlled trials (RCTs) and perform meta-analysis.

OBJECTIVES

To describe the heterogeneity in outcome measures used in published RCTs of vitiligo treatments, and to report the most desirable outcomes from patients' and clinicians' perspectives.

METHODS

We conducted a systematic review of outcome measures used in RCTs as well as a survey of the most desirable outcomes identified by patients and clinicians as part of a Vitiligo Priority Setting Partnership.

RESULTS

Outcomes from 54 eligible trials were analysed and compared with outcomes suggested by patients and clinicians. In the systematic review, 25 different outcomes were reported. Only 22% of trials had clearly stated primary outcome measures. Repigmentation was the most frequently reported outcome in 96% of trials and was measured using 48 different scales. Only 9% of trials assessed quality of life. Thirteen per cent measured cessation of spreading of the disease and 17% of studies reported patients' opinions and satisfaction with the treatment. In contrast, out of 438 suggestions made by patients and clinicians, cosmetically acceptable repigmentation (rather than percentage of repigmentation) was the most desirable outcome (68%), followed by cessation of spread of vitiligo (15%), quality of life (8%) and maintenance of repigmentation (4%).

CONCLUSIONS

We propose that future vitiligo trials should include repigmentation, cosmetic acceptability of results, global assessment of the disease, quality of life, maintenance of repigmentation, stabilization of vitiligo and side-effects. International consensus among clinicians, researchers and patients is needed to establish an agreed core outcome set for future vitiligo trials.

Guidelines for the management of vitiligo: the European Dermatology Forum consensus

The aetiopathogenic mechanisms of vitiligo are still poorly understood, and this has held back progress in diagnosis and treatment. Up until now, treatment guidelines have existed at national levels, but no common European viewpoint has emerged. This guideline for the treatment of segmental and nonsegmental vitiligo has been developed by the members of the Vitiligo European Task Force and other colleagues. It summarizes evidence-based and expert-based recommendations (S1 level).

Evidence-based, non-surgical treatments for vitiligo: a review

Vitiligo is an acquired pigmentary disorder characterized by depigmented macules and patches secondary to the loss of functional melanocytes. It is a chronic disease that affects between 0.1% and 2% of the general population, affecting both sexes and all races. The appearance and the unpredictable course are psychologically and socially devastating. The success of current therapeutic options is limited. The objective of this review was to assess non-surgical treatments of vitiligo and to determine if comparing these studies can lead to (1) practical applications in the clinical setting and (2) recommendations for future research including study design and topics to be investigated further. Combination therapies were found to be more effective than monotherapy, and most combinations included a form of phototherapy, of which narrow-band-UVB was found to be most effective with the least adverse effects. Topical treatment with corticosteroids, immunomodulators, vitamin D analogs, and psoralens had mixed outcomes. Oral therapies including antioxidants were helpful adjuvants to treatment. Studies lacked consistent design, mechanism of disease assessment, and long-term follow-up. Sample size was also frequently limited. This review found that while several non-surgical therapies exist for the treatment of vitiligo, their usefulness, especially in the long term, is not well understood. Those studies that were able to elicit repigmentation often lacked an assessment on quality of life and/or patient satisfaction. More standardized methods of study design and assessment are needed to compare outcomes and make definitive conclusions on treatment effectiveness.

Effect of a preceding laser dermabrasion on the outcome of combined therapy with narrowband ultraviolet B and potent topical steroids for treating nonsegmental vitiligo in resistant localizations

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 3weeks followed by a 1-week steroid-free interval and narrowband UVB treatment was performed on both sides twice weekly for 12weeks. 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%, 1month 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.

Vitiligo: a comprehensive overview Part II: treatment options and approach to treatment

Vitiligo is a common skin disorder that results in depigmentation. With the appropriate management, many patients can minimize disease progression, attain repigmentation, and achieve cosmetically pleasing results. There are numerous medical and surgical treatments aimed at repigmentation; therapies for depigmentation are available for patients with recalcitrant or advanced disease. The use of cosmetics at all stages of treatment may be vital to the patient's quality of life. Understanding all the available options helps choose the appropriate treatment plan and tailor it to your patient. Part II of this two-part series on vitiligo discusses the indications for, evidence behind, and adverse effects associated with many of the therapies used for vitiligo. Both conventional medical and surgical options are discussed in addition to several alternative and promising new therapies.

Vitiligo treatment in childhood: a state of the art review

Vitiligo is a common depigmenting disorder affecting about 1-2% of the world population. Approximately half of the affected individuals develop the disease before adulthood. Etiologic hypotheses for vitiligo include biochemical, neural and autoimmune mechanisms. The most compelling of these suggests a combination of genetic and immunologic factors that result in an autoimmune melanocyte destruction. We reviewed studies carried out on various treatment modalities used in childhood vitiligo. Topical corticosteroids were found to have excellent repigmentation rates, whereas calcineurin inhibitors have comparable efficacy and a better safety profile compared with topical corticosteroids. These two groups of topical medications are good first-line treatment modalities for localized vitiligo. For the treatment of generalized vitiligo, phototherapy has excellent efficacy. Narrow-band ultraviolet B (UVB) has better overall repigmentation rates and safety profile than either topical or oral psoralens and ultraviolet A (PUVA). Other treatment modalities may be considered depending on a patient's specific condition, such as surgical options and depigmentation. With adequate sun protection, the option of no treatment with or without corrective camouflage, is an innocuous alternative to any of these treatment modalities.

Innovative use of topical calcineurin inhibitors

Topical tacrolimus and pimecrolimus are indicated for treatment of atopic dermatitis, but they have been studied in many off-label uses. Double-blind and open studies have shown favorable results with topical tacrolimus and pimecrolimus in oral lichen planus. In 1 study of oral lichen planus, blood tacrolimus was detected in 54% of patients, but there were no signs of systemic toxicity. Double-blind and open studies of vitiligo have shown favorable results with tacrolimus in combination with excimer laser, especially for lesions over bony prominences and on extremities. Similarly, double-blind studies of vitiligo have shown favorable results when pimecrolimus is combined with narrow-band UVB, especially for facial lesions. Double-blind and open studies of psoriasis have shown favorable results for tacrolimus and pimecrolimus, especially for inverse psoriasis. Topical calcineurin inhibitors have been effective in many other cutaneous disorders, and further studies would help clarify their roles.

Update on childhood vitiligo

PURPOSE OF REVIEW

This review addresses recent changes in the understanding and the treatment of vitiligo vulgaris.

RECENT FINDINGS

Two target genes for vitiligo have been identified, NACHT-leucine-rich-repeat protein-1 (NALP1), part of the inflammasome cascade, and tyrosinase, the enzyme that produces melanin. Identification of reactive oxidation species has furthered the understanding of melanocyte destruction. Comorbid autoimmune disease, including thyroid autoimmunity seen in 25%, is genetically linked to generalized vitiligo and is noted in both childhood vitiligo patients and their families. Screening for vitamin deficiencies and concurrent autoimmunity can be beneficial to the overall health of the child with vitiligo. About half of all vitiligo vulgaris patients have onset of their illness during childhood, causing increased psychological stress during the formative years. Fortunately, therapy has improved as well, with the development of newer topical agents for vitiligo, including topical calcineurin inhibitors; new topical combinations such as topical corticosteroids and calcipotriene; and new technological advances including narrowband ultraviolet B and excimer laser.

SUMMARY

A cyclic approach to therapy should be used wherein topical agents are altered every 6-8 months and technology is used as an alternative after achievement of maximal topical response. With cyclic therapy and early disease intervention, good cosmetic outcomes may be achievable, particularly in localized cases.

Interventions for vitiligo

BACKGROUND

Around one per cent of the world's population has vitiligo, a disease which causes white patches on the skin. There are a variety of treatments available, most of which are unsatisfactory.

OBJECTIVES

To assess all interventions used to manage vitiligo.

SEARCH STRATEGY

In November 2009 we updated searches of the Cochrane Skin Group Specialised Register, the Cochrane Central Register of Controlled Trials in The Cochrane Library (Issue 4, 2009), MEDLINE, EMBASE, AMED, PsycINFO, LILACS and ongoing trials databases.

SELECTION CRITERIA

Randomised controlled trials (RCTs).

DATA COLLECTION AND ANALYSIS

At least 2 review authors independently assessed study eligibility and methodological quality, and carried out data extraction. Two of the 57 included studies could be combined for meta-analysis.

MAIN RESULTS

In this update, 57 trials, including 19 from the original review, were assessed with 3139 participants. Most of the RCTs, which covered a wide range of interventions, had fewer than 50 participants. All of the studies assessed repigmentation, 6 measured cessation of spread, and 5 investigated the effect of treatment on quality of life.Most of the studies assessed combination therapies which generally reported better results. New interventions include monochromatic excimer light (MEL), Polypodium leucotomos, melanocyte transplantation, oral antioxidants, Chinese zengse pill, and pimecrolimus. We analysed the data from 28 studies that met our outcome criteria of improvement in quality of life and greater than 75% repigmentation.Fifteen analyses from studies comparing various interventions showed a statistically significant difference between the proportions of participants achieving more than 75% repigmentation. The majority of analyses showing statistically significant differences were from studies that assessed combination interventions which generally included some form of light treatment.Topical preparations, in particular corticosteroids, reported most adverse effects. However, in the combination studies it was difficult to ascertain which treatment caused these effects. None of the studies was able to demonstrate long-term benefits. Very few studies were conducted on children or included segmental vitiligo. We found one study of psychological interventions and none evaluating micropigmentation, depigmentation, or cosmetic camouflage.

AUTHORS' CONCLUSIONS

This review has found some evidence from individual studies to support existing therapies for vitiligo, but the usefulness of the findings is limited by the different designs and outcome measurements and lack of quality of life measures. There is a need for follow-up studies to assess permanence of repigmentation as well as high quality randomised trials using standardised measures and which also address quality of life.

Pigmentary disorders

A large number of pigmentary disorders exist and although not all dermatologic entities are covered in this article, some of the pigmentary disorders that an internist or general practitioner is likely to encounter are reviewed. The clinician must be able to recognize pigmentary changes that suggest a serious underlying disease. In a situation where a malignancy or other serious illness may exist, an extensive evaluation to detect the disorder is required. This approach can allow for early treatment and referral to an appropriate specialist if necessary. The clinician must also recognize that pigmentary disorders that are essentially cosmetic still cause concern for the patient and can be emotionally distressing. These patients need emotional support and in some cases referral to a mental health specialist.
