Development of evidence‐based consensus on critical issues in the management of patients with vitiligo: A modified Delphi study

Combined tofacitinib citrate and 308-nm excimer laser treatment for vitiligo: a pilot study

BACKGROUND

Vitiligo is a clinically prevalent acquired skin disorder characterized by depigmentation. Currently, the therapeutic options for vitiligo are restricted, and numerous issues exist, such as a prolonged treatment course, unsatisfactory therapeutic efficacy, adverse reactions and a high propensity for recurrence after treatment cessation.

OBJECTIVES

To assess the safety and efficacy of combined treatment involving oral tofacitinib citrate (TC) and a 308-nm excimer laser (EL), with the aim of discovering a rapid and effective treatment approach to minimize the side-effects of various drugs.

METHODS

In total, 63 patients with progressive vitiligo and a Vitiligo Disease Activity Score of 4 from January 2022 to January 2024 were enrolled and divided into three groups. The three groups were: the TC combined with 308-nm EL and methylprednisolone treatment group (group 1); the TC and 308-nm EL treatment group (group 2); and the methylprednisolone alone treatment group (group 3). The treatment was continued for 24 weeks, and an assessment of therapy outcomes was performed.

RESULTS

When TC was combined with 308-nm EL and methylprednisolone treatment (group 1), the effect was more rapid than in the other two groups. When TC was combined with 308-nm EL (group 2), it had a more favourable treatment effect than that of methylprednisolone alone (group 3), despite having a slower onset of effect. After 24 weeks of treatment, there was no significant difference between group 1 and group 2 in terms of the total response rate or significant response. However, when only methylprednisolone treatment was applied, the effect was relatively slow and ineffective.

CONCLUSIONS

This study confirmed a rapid and effective treatment of vitiligo was achieved through a combination of TC and 308-nm EL. No serious adverse reactions were reported, and therefore this could potentially offer an optimal treatment plan for patients with vitiligo.

Epidemiology and Treatment Patterns of Patients with Vitiligo: A Real-World Analysis

INTRODUCTION

Vitiligo, a chronic autoimmune skin depigmentation disease with an unpredictable course, has been associated with several comorbid autoimmune and psychological conditions. Our current understanding of vitiligo burden and management in the real world is limited. This real-world analysis presents data on vitiligo epidemiology, comorbidities, and treatment of patients in Israel.

METHODS

This retrospective study analyzed data from the Maccabi Health Services database. Prevalent patients with vitiligo in 2021 were matched to patients in the general population on the basis of age group, gender, and socioeconomic status. Patient demographics, vitiligo incidence and prevalence, comorbidities, and treatment patterns are reported. Data are presented as percentages, mean, median, P values, and standard mean differences (SMD).

RESULTS

In this analysis, 11,412 patients with vitiligo were matched to patients from the general population. Incidence and prevalence rates increased over time from 2005 to 2021. Compared to the general population, patients with vitiligo were more likely to have an immune-mediated comorbidity (29.7% vs 18.4% [P < 0.001; SMD 0.27]) or psychological comorbidity (18.7% vs 15.9% [P < 0.001; SMD 0.07]). Comorbidities included atopic dermatitis (patients with vitiligo vs general population 12.5% vs 8.4%), psoriasis (5.8% vs 3.6%), Hashimoto's thyroiditis (2.9% vs 1.1%), alopecia areata (2.2% vs 0.9%), depression (10.8% vs 9.5%), and sleep disorder/insomnia (5.9% vs 4.4%). Only 74.8% of all patients with vitiligo had ever received treatment, with topical corticosteroids (51.5%) and calcineurin inhibitors (36.5%) most commonly prescribed. At the end of 2021, 83.7% of patients were untreated.

CONCLUSION

Patients with vitiligo are more likely to have various immune-related and psychological comorbidities, highlighting the significant impact of the condition on well-being. Nearly a quarter of patients had never received treatment, with many receiving only topical treatments, and medication persistence was low. This highlights the lack of adequate treatment in this population and the need for more effective management options.

A review of JAK and IL-23 inhibitors to treat vitiligo

Vitiligo is an autoimmune skin disorder resulting in the depigmentation of skin characterised by patches of varying sizes and shapes. A common disorder of pigmentation that affects 0.5%-2% of the global population. Despite its well-understood autoimmune pathogenesis, the targets for effective cytokine intervention remain unclear. Current first-line treatments include oral or topical corticosteroids, calcineurin inhibitors and phototherapy. These treatments are limited, have varying efficacies, and are associated with significant adverse events or can be time-consuming. Therefore, biologics should be explored as a potential treatment for vitiligo. There are currently limited data for the use of JAK and IL-23 inhibitors for vitiligo. A total of 25 studies were identified in the review. There is promising evidence regarding the use of JAK and IL-23 inhibitors for the treatment of vitiligo.

The long-term risk of lymphoma and skin cancer did not increase after topical calcineurin inhibitor use and phototherapy in a cohort of 25,694 patients with vitiligo

BACKGROUND

Topical calcineurin inhibitors have been used to treat vitiligo, either alone or in combination with phototherapy; however, the long-term safety of these agents remains controversial.

OBJECTIVE

To investigate the risk of lymphoma and skin cancer in vitiligo patients who received topical calcineurin inhibitors or phototherapy.

METHODS

A multicenter retrospective cohort study of 25,694 vitiligo patients who received topical calcineurin inhibitors or phototherapy for 6 weeks or more between 2001 and 2019 was performed. Cumulative doses of topical calcineurin inhibitors and total phototherapy sessions were determined. Outcomes were the development of lymphoma or skin cancer after enrollment, confirmed through chart review and pathology reports.

RESULTS

During 95,203 person-years, 13 cases of lymphoma, 22 of actinic keratosis, 15 of nonmelanoma skin cancer, and 5 of melanoma were observed. The risk of lymphoma and skin cancer was not significantly increased by topical calcineurin inhibitor dose or phototherapy sessions. The interaction between the topical calcineurin inhibitors and phototherapy was not associated with an increased risk of skin cancer.

LIMITATIONS

Retrospective study, individual follow-up duration less than 4 years, and no adjustment for comorbidities and medication history. Not generalizable to other races.

CONCLUSION

The long-term risk of skin cancer or lymphoma was not associated with the use of topical calcineurin inhibitors, phototherapy, and both treatments in combination in patients with vitiligo.
