Importance: New targeted therapies for cancer have been released in recent years, opening new horizons in the treatment of patients with cancer. However, their related adverse events (AE) are not fully characterized. Hair repigmentation (HR) is a nondescribed effect secondary to anti-programmed cell death 1 (anti-PD-1) and anti-programmed cell death ligand 1 (anti-PD-L1 ) therapy for treatment of lung cancer (LC), in opposition to the vitiligo reactions that develop during melanoma treatment...

<p>BACKGROUND: Treatment of vitiligo is aimed at repigmentation and often consists of multiple modalities, none of which are universally or rapidly successful. Extensive cases are most often treated with ultraviolet light therapy, which can be both costly and time-consuming. Though vitiligo is an autoimmune disease, there is no current data to support systemic immunosuppressive monotherapy.</p> <p>CASE SUMMARY: Here we present a case series of 3 patients with vitiligo treated for 11-16 months with low-dose methotrexate (12...

Vitiligo is a disorder characterized by the development of depigmented macules and patches. Narrowband ultraviolet B phototherapy is a standard of care treatment and is used both as monotherapy and in combination with other treatment modalities to induce repigmentation. Although phototherapy is safe and effective, its use is limited due to the significant time commitment required and associated costs. Home phototherapy is a safe and effective alternative to make phototherapy more accessible to patients. However, it is often underutilized due to lack of physician experience and comfort as well as misconceptions regarding its safety and efficacy...

Clinicians should be aware that vitiligo is not merely a cosmetic disease and that there are safe and effective treatments available for vitiligo. It is important to recognize common and uncommon presentations and those with active disease, as well as their implications for clinical management; these were discussed in the first article in this continuing medical education series. Existing treatments include topical and systemic immunosuppressants, phototherapy, and surgical techniques, which together may serve to halt disease progression, stabilize depigmented lesions, and encourage repigmentation...

Vitiligo is a common acquired depigmentation disorder for which many treatments have previously been used with varying effects. The aim of the present study was to evaluate the efficacy and safety of targeted high-intensity (TH) and narrow band (NB) ultraviolet B light (UVB) for vitiligo treatment. A total of 33 patients with vitiligo were enrolled in the present study. Patients with a symmetrical or near-symmetrical distribution of lesions on their bodies were selected for the present study. For each patient, half of the body was treated with TH-UVB and the other with NB-UVB twice weekly over a period of 12 weeks (24 times total)...

The pathophysiology of vitiligo is becoming increasingly clarified. In non-segmental vitiligo, early factors include activation of innate immunity, inflammasome activation, oxidative stress, and loss of melanocyte adhesion. Nonetheless, the main mechanism leading to non-segmental vitiligo involves an immune-mediated destruction of melanocytes. Anti-melanocyte-specific cytotoxic T cells exert a central role in the final effector stage. Genetic research revealed a multi-genetic inheritance displaying an overlap with other autoimmune disorders...

The current methods for melanocyte delivery to depigmented skin are invasive and often require sophisticated approaches. Here we describe a promising simple and minimally invasive technique based on the dermarolling system. The technique involves preparation of a keratinocyte/melanocyte suspension prepared by trypsinization from a non-lesioned part of a patient's scalp skin and transepidermal delivery using a dermaroller equipped with 0.2 mm needles. Dermarolling leads to epidermal microinjuries without, however, causing pain or inflammation...

BACKGROUND & AIMS: Vitiligo is a pigmentary disorder and autoimmune pathogenesis seems most likely. Decreased vitamin D levels have been related to several autoimmune diseases. Little is known about the association of vitiligo and vitamin D. We aimed to evaluate serum 25-hydroxyvitamin D [25(OH)D] levels in children with vitiligo and to determine the efficacy of oral vitamin D therapy on the repigmentation of vitamin D deficient patients. METHODS: Thirty patients aged 6-17 years with vitiligo and 30 sex- and age-matched apparently healthy controls were included in this prospective study...

Phenytoin is normally used in epilepsy treatment. One of the side effect affecting a significative part of the treated patients is the gingival overgrowth. It could surely be a correlation between this stimulatory effect and the assessment of phenytoin in wound healing. In fact, some studies of the literature have shown that topical phenytoin promotes healing of traumatic wounds, burns and ulcers by decubitus or stasis (diabetic or venous) and we emphasize, in vitiligo, a particular attention into repigmentation...

Vitiligo is an intriguing depigmentary disorder and is notoriously difficult to be treated. The ultimate goal of vitiligo treatment is to replenish the lost melanocytes by immigration from hair follicle and to restore the normal function of melanogenesis by residual melanocytes. There are two types of topical calcineurin inhibitors called tacrolimus and pimecrolimus, and are recommended as the first-line treatments in vitiligo. Although pimecrolimus is efficacious for the repigmentation of vitiligo, its intrinsic mechanisms have never been investigated in vitro...

BACKGROUND: Though vitiligo is a common depigmentary disorder, it still represents a substantial therapeutic challenge. Therapeutic options are limited in part due to its uncertain etiology. OBJECTIVE: Because recent studies suggest that histamine stimulates melanogenesis in vitro, we determined here whether topical histamine stimulates repigmentation in patients with stable, nonsegmental vitiligo. METHODS: A total of 23 otherwise normal volunteers with vitiligo, including 14 males and 9 females aged 6-59 years (mean age 29...

BACKGROUND: Autologous non-cultured cell suspension transplantation is an effective treatment for repigmentation in segmental vitiligo and piebaldism. Full surface laser ablation is frequently used to prepare the recipient site before cell suspension transplantation, even though optimal laser settings and ablation depth are unknown. OBJECTIVES: To assess the efficacy and safety of less invasive recipient site preparations. METHODS: In a randomised, observer-blinded, controlled trial we compared different recipient site preparations before cell suspension transplantation in segmental vitiligo and piebaldism...
