Worldwide expert recommendations for the diagnosis and management of vitiligo: Position statement from the international Vitiligo Task Force-Part 2: Specific treatment recommendations.

BACKGROUND: The treatment of vitiligo can be challenging. Up-to-date agreed consensus recommendations on the use of topical and systemic therapies to facilitate the clinical management of vitiligo are currently lacking. OBJECTIVES: To develop internationally agreed-upon expert-based recommendations for the treatment of vitiligo. METHODS: In this consensus statement, a consortium of 42 international vitiligo experts and four patient representatives participated in different online and live meetings to develop a consensus management strategy for vitiligo. At least two vitiligo experts summarized the evidence for different topics included in the algorithms. A survey was then given to a core group of eight experts to resolve the remaining issues. Subsequently, the recommendations were finalized and validated based on further input from the entire group during two live meetings. RESULTS: The recommendations provided summarize the latest evidence regarding the use of topical therapies (steroids, calcineurin inhibitors and Jak-inhibitors) and systemic therapies, including steroids and other systemic immunomodulating or antioxidant agents. The different modalities of phototherapies (NB-UVB, photochemotherapy, excimer devices and home phototherapy), which are often combined with other therapies, are also summarized. Interventional approaches as well as depigmentation strategies are presented for specific indications. Finally, the status of innovative and targeted therapies under development is discussed. CONCLUSIONS: This international consensus statement culminated in expert-based clinical practice recommendations for the treatment of vitiligo. The development of new therapies is ongoing in vitiligo, and this will likely improve the future management of vitiligo, a disease that still has many unmet needs.

Expert opinion about laser and intense pulsed light (IPL)-induced leukoderma or vitiligo: a cross-sectional survey study.

Vitiligo patients may desire laser hair removal, skin rejuvenation, vascular treatments, and other laser or intense pulsed light (IPL) assisted treatments. However, there is a risk of inducing new depigmented patches (Koebner phenomenon). In absence of guidelines on the safe use of laser or IPL in vitiligo patients, dermatologists tend to be reluctant to administer these treatments. The aim of this survey study was to provide an estimation of the occurrence and related risk factors of laser/IPL-induced leukoderma or vitiligo. A cross-sectional survey study was performed among 15 vitiligo experts from 11 countries, with 14 questions about affected patients, involved laser/IPL treatments and the physicians' approach. In a total of 11,300 vitiligo patients, laser/IPL-induced leukoderma or vitiligo was reported in 30 patients (0.27%). Of these, 12 (40%) patients had a medical history of vitiligo and seven (58%) of these patients had stable (> 12 months) vitiligo before the treatment. Most frequently reported were hair removal procedures and localization of the face and legs. Side effects like blistering, crusting, and erosions occurred in 56.7% of the cases. These vitiligo experts based their advice on the risk of the laser treatment on stability of the vitiligo (43%) and activity signs (50%), and 50% discuss the risks before starting a laser treatment. Relevant activity signs are the Koebner phenomenon (57.1%), confetti-like lesions (57.1%) and hypochromic borders (50%). Laser-induced leukoderma or vitiligo is an uncommon phenomenon. Remarkably, a minority had a medical history of vitiligo of which 58% were stable. Consequently, most cases could not have been prevented by not treating vitiligo patients. However, a majority had laser/IPL-induced skin damage. Therefore, caution is advised with aggressive settings and test-spots prior to the treatment are recommended. This study showed significant variation in the current recommendations and approach of vitiligo experts regarding laser/IPL-induced leukoderma or vitiligo.

Using Failure Mode, Effect and Criticality Analysis to improve safety in the cancer treatment prescription and administration process.

BACKGROUND: Administering cancer drugs is a high-risk process, and mistakes can have fatal consequences. Failure Mode, Effect and Criticality Analysis (FMECA) is a widely recognized method for identifying and preventing potential risks, applied in various settings, including healthcare. The aim of this study was to recognize potential failures in cancer treatment prescription and administration, with a view to enabling the adoption of measures to prevent them. METHODS: This study consists of a FMECA. A team of resident doctors in public health at the University of Padua examined the cancer chemotherapy process with the support of a multidisciplinary team from the Veneto Institute of Oncology (an acknowledged comprehensive cancer center), and two other provincial hospitals. A diagram was drafted to illustrate 9 different phases of chemotherapy, from the adoption of a treatment plan to its administration, and to identify all possible failure modes. Criticality was ascertained by rating severity, frequency and likelihood of a failure being detected, using adapted versions of already published scales. Safety strategies were identified and summarized. RESULTS: Twenty-two failure modes came to light, distributed over the various phases of the cancer treatment process, and seven of them were classified as high risk. All phases of the cancer chemotherapy process were defined as potentially critical and at least one action was identified for a single high-risk failure mode. To reduce the likelihood of the cause, or to improve the chances of a failure mode being detected, a total of 10 recommendations have been identified. CONCLUSIONS: FMECA can be useful for identifying potential failures in a process considered to be at high risk. Safety strategies were devised for each high-risk failure mode identified.

Phototherapy for vitiligo, what's new?

Vitiligo is a disorder characterized by the development of depigmented macules and patches. Existing treatments include topical and systemic immunosuppressants, topical vitamin D analogues in monotherapy or in association with phototherapy, phototherapy and surgical techniques, which together may serve to halt disease progression, stabilize depigmented lesions, and encourage repigmentation. Narrow-band UVB (NB-UVB 310-315 nm) radiation is now considered as the "gold standard" for the treatment of diffuse vitiligo. This article provides a brief overview of the different phototherapy based treatments in vitiligo.

The Vitiligo Working Group recommendations for narrowband ultraviolet B light phototherapy treatment of vitiligo.

BACKGROUND: Treatment of vitiligo with narrowband ultraviolet B light (NBUVB) is an important component of the current standard of care. However, there are no consistent guidelines regarding the dosing and administration of NBUVB in vitiligo, reflected by varied treatment practices around the world. OBJECTIVE: To create phototherapy recommendations to facilitate clinical management and identify areas requiring future research. METHODS: The Vitiligo Working Group (VWG) Phototherapy Committee addressed 19 questions regarding the administration of phototherapy over 3 conference calls. Members of the Photomedicine Society and a group of phototherapy experts were surveyed regarding their phototherapy practices. RESULTS: Based on comparison and analysis of survey results, expert opinion, and discussion held during conference calls, expert recommendations for the administration of NBUVB phototherapy in vitiligo were created. LIMITATIONS: There were several areas that required further research before final recommendations could be made. In addition, no standardized methodology was used during literature review and to assess the strength of evidence during the development of these recommendations. CONCLUSION: This set of expert recommendations by the VWG is based on the prescribing practices of phototherapy experts from around the world to create a unified, broadly applicable set of recommendations on the use of NBUVB in vitiligo.

Photo(chemo)therapy for vitiligo.

Vitiligo is a common skin disease characterized by loss of normal melanin pigments in the skin and its pathogenesis is still unclear. Treatment modalities include psoralen plus ultraviolet A, narrow-band ultraviolet B (NB UVB) phototherapy, topical and systemic steroids, topical calcineurin inhibitors, topical vitamin D analogues in monotherapy or in association with phototherapy, and surgical treatment. NB UVB (310-315 nm) radiation is now considered as the 'gold standard' for the treatment of diffuse vitiligo, and treatment with two recently introduced UVB sources that emit 308 nm wavelengths, the 308 nm xenon chloride (XeCl) excimer laser and the 308 nm XeCl excimer light, has also been reported to be effective and might be the treatment of choice for localized disease: this treatment modality has been defined as 'targeted phototherapy.'

A comparative non randomized study of narrow-band (NB) (312 +/- 2 nm) UVB phototherapy versus sequential therapy with oral administration of low-dose Cyclosporin A and NB-UVB phototherapy in patients with severe psoriasis vulgaris.

Sequential therapy may improve the efficacy and safety of single treatments for severe psoriasis. We compared sequential Cyclosporin A and narrow-band UVB phototherapy versus narrow-band UVB phototherapy alone. A group of 30 patients with severe psoriasis received 3 mg/kg/day Cyclosporin A for 4 weeks. Afterwards, Cyclosporin A was rapidly tapered and phototherapy begun. An additional 30 patients received phototherapy alone. Treatments were given until psoriasis cleared or until partial improvement was achieved without further amelioration despite another week of treatment. Both treatments were highly effective and well tolerated but sequential therapy was more effective in lesions of UV-shielded body areas; itching disappeared more quickly. The cumulative narrow-band UVB dosages and number of exposures were lower. No difference was seen at follow-up extended up to 9 months. Sequential therapy was well tolerated and allowed for the reduction of narrow-band UVB dosage and exposures, quick relief of itching and improvement of UV-shielded lesions.

Profile of clinical efficacy and safety of topical tacalcitol.

Several topical treatments such as ointments, keratolytics, dithranol, tar, corticosteroids and Vitamin D3 analogues are commonly used in the treatment of mild and/or moderate psoriasis. These treatments can be associated with a variety of local and systemic side effects, as well as to very often unsatisfactory results. The purpose of this critical review of the literature is to evaluate the efficacy and tolerability of the synthesis of new analogues of the Vitamin D3 Tacalcitol, which is formulated in ointment form at a concentration of 4 microg/g, for the treatment of mild and/or moderate psoriasis (involvement of <20% of the surface of the skin) and to evaluate whether this drug can be used in the treatment of other skin conditions. Based on existing data in the literature, Tacalcitol is an effective drug for the topical treatment of psoriasis and is also able to ensure that the effects last over time, even after treatment has stopped. Tacalcitol is also well tolerated because the onset of side effects, such as local irritation, pruriginous or burning sensations, were reported in only a small percentage of the subjects who were treated. Lastly, the marked regulatory effects it has on the proliferation and differentiation of keratinocytes, as well as on the immunocompetent cells, has led to suggestions that Tacalcitol may be used in other keratinisation disorders and in some hyperproliferative skin diseases. Evaluation of the effective indications to use in these conditions still requires further data confirming its effectiveness, opening the way to wider use of this molecule in dermatology.
