Vitiligo is an autoimmune skin disease presenting with areas of depigmentation. Recent reports suggest that Janus kinase (JAK) inhibitors may be an effective therapy. In this case report, we show our experience with an adolescent patient with a long history of generalized and refractory vitiligo, for which treatment with topical tofacitinib, a JAK inhibitor, associated with phototherapy for 9 months, resulted in near complete repigmentation.

Vitiligo is a chronic autoimmune disease characterized by the progressive disappearance of melanocytes, causing depigmentation. The standard treatment includes topical and systemic corticosteroids, topical calcineurin inhibitors, psoralens, and phototherapy (narrow-band [NB]-UVB and UVA combined with psoralen); however, none of those treatments are reliably effective [1]. Recent reports and studies have shown benefits from both oral and topical Janus kinase (JAK) inhibitors in adults with vitiligo [2-4].

We report on the case of a 17-year-old boy with stable nonsegmental vitiligo with acrofacial involvement (Fig. 1) with a 15-year evolution. He had no other clinical or autoimmune condition and denied any family history of vitiligo. Previous treatments included oral corticosteroids for 4 years, alternating 6 months each because of unstable vitiligo, antioxidants, and oral vitamin D, topical tacrolimus for 6 months, and topical corticosteroids for another 6 months.

a At baseline, the 17-year-old boy had an evident and continuous white macule along his forehead, right and left periorbital region, nose, and lips, as well as a single macule right above his right clavicle. b After 9 months of therapy, repigmentation was near complete in both periorbital regions, around his lips, and above his clavicle, besides great improvement in the nasal area.

He had done 1 year of phototherapy (NB-UVB) with no improvement at all, as well as NB-UVB associated with topical corticosteroids and topical tacrolimus during 3 years, with little improvement. As previous reports have suggested [2], light exposure in patients using JAK inhibitors as a therapy for vitiligo may improve repigmentation; thus, considering the high cost of the treatment, the patient already started on a combined therapy: topical tofacitinib 2% + vehicle (ointment) (Chemistry Rx Compounding and Specialty Pharmacy, Folcroft, PA, USA) twice daily only on the facial lesions, combined with NB-UVB phototherapy, 3 times a week, during 9 months. The total dose for the face vitiligo was 1,000 mJ/cm2, starting with 200 mJ/cm2 and increasing by 50 mJ/cm2 each session.

Before he started on topical tofacitinib, the patient underwent a baseline laboratory evaluation. During treatment, he repeated the tests, which revealed no abnormalities. A complete review of his systems was negative. After 9 months of therapy, significant repigmentation of the forehead, nose, eyes, and lips was observed (Fig. 2). He had minor adverse events such as erythema and transient acne.

A new hypothesis about the pathogenesis of vitiligo suggests that both genetic and nongenetic factors interfere in melanocytes, resulting in their immune-mediated destruction [5]. Recent studies have shown that in the pathogenesis of vitiligo, CD8+ T cells and interferon-γ play key roles in the destruction of melanocytes [6].

Tofacitinib is a JAK inhibitor approved by the US Food and Drug Administration in 2012 and by ANVISA (National Agency of Sanitary Vigilance in Brazil) for the treatment of rheumatoid arthritis and psoriatic arthritis. Tofacitinib is a JAK1 and JAK3 inhibitor that interferes with interferon-γ signaling, which reduces CXCL10 chemokine expression, blocking the activity of vitiligo. The first case suggesting this possible mechanism of action of JAK inhibition was published by Craiglow and King [3]. The success and safety of both oral and topical tofacitinib were shown for the treatment of alopecia areata, including in adolescents [7, 8]. Additional studies and clinical trials of tofacitinib for the treatment of other dermatological and nondermatological conditions are currently underway.

Other case reports on oral and topical JAK inhibitors for vitiligo [2], as well as recently an open-label study with topical 1.5% ruxolitinib cream, showed good results for facial vitiligo [9]. However, there are only limited numbers of case reports for the pediatric and adolescent populations [10]. In our patient, all previous treatments had failed, including systemic corticosteroids, whereas with topical tofacitinib, he experienced considerable facial repigmentation; however, we are aware that longer treatments will probably be necessary for complete repigmentation.

As vitiligo has a remarkable impact on quality of life and can be emotionally devastating, some patients are at higher risk of social discrimination and stigma; therefore, new possibilities of targeted treatments are welcome. This case suggests that topical tofacitinib might be a safe and effective therapy for vitiligo, especially for pediatric and adolescent patients, for whom systemic therapies are not desired. Additional clinical trials will be needed to confirm any real advances and tofacitinib’s efficacy in the management of this complex disease.
