Active clinical trials for "Vitiligo"

A randomized controlled non-inferiority trial based on split-body was planned to compare the efficacy of 308-nm excimer laser and 311-nm Ti:Sapphire laser in patients with vitiligo.

Actually the methods for melanocyte delivery are invasive and often sophisticated. The dermarolling system with needles causing tiny microinjuries in the epidermis could offer a minimally invasive and painless method of melanocyte transplantation. The purpose of the study is to develop a new and simple method for transepidermally delivering keratinocytes and melanocytes into vitiligo skin.

Vitiligo is an acquired disorder of the skin and mucous membranes characterized by well circumscribed depigmented macules and patches that occur secondary to selective destruction of melanocytes (Zhang et al., 2009). Generalized vitiligo is the most common clinical presentation and often involves the face and acral regions (Alikhan et al., 2011).

A randomized split-body pilot study was planned to confirm efficacy of intralesiona triamcinolone injection in patients with vitiligo

Although vitiligo is difficult to cure, recurrences are frequent after treatment, and many patients suffer from concerns about recurrence as well as disease. Psoriasis, another indication for ultraviolet radiation treatment, has been established that it can safely and effectively reduce the recurrence of psoriasis through monthly maintenance therapy. The aim of this study was to evaluate the efficacy of 308-nm excimer laser therapy for the prevention of relapse in vitiligo.

Vitiligo is a complex disease causing a selective, often progressive, loss of functioning melanocytes from epidermal basal layer resulting in white patches on the skin and occasionally mucosae. Worldwide prevalence of vitiligo is around 1% whereas in India it is around 3-4% ranging from 0.46% to 8.8%. Etiopathogenesis of vitiligo is multifactorial consisting of genetic, immunological and environmental factors. Environmental and genetic factors act in concert to destroy melanocytes. Reactive oxygen species (ROS) play important roles in vitiligo pathology,but the autoimmune pathogenesis has been proposed as one of the main causes of vitiligo. Surgical methods, mainly transplantation of non cultured epidermal cell suspension are effective treatment for stable vitiligo. Transplantation of autologous noncultured epidermal cell suspension and non-cultured dermal cell suspension in combination (a mode of cellular grafting technique) is a novel surgical method for the treatment of vitiligo. Cytotoxic CD8+ ( cluster of differentiation 8+) cells in vitiligo perilesions may dictate the fate of transplantation, and strategies against CD8+ T cell activation might be beneficial for patients undergoing melanocyte transplantation. Mesenchymal cells could inhibit T cell proliferation and induce T cell apoptosis. Bartsch first identified and characterized dermal mesenchymal cells (DMCs). They have a multi-lineage differentiation potential into adipocytes, osteocytes and chondrocytes.Vitiligo patients' autologous melanocytes transplantation efficiency may be predicted by perilesional skin-homing CD8+ T cell activities, and the immunoregulatory DMCs might be used as auxiliary agent to improve the efficacy. This pilot study is planned to compare transplantation of autologous noncultured epidermal cell suspension v/s its combination with non-cultured dermal cell suspension as a novel method in vitiligo surgery in stability of vitiligo with regards to extent of repigmentation, color matching of repigmented area, patient satisfaction and adverse events if any. This is the first study using transplantation of autologous noncultured epidermal cell suspension and non-cultured dermal cell suspension in combination as a new modality in vitiligo surgery.

Prospective randomized within-subject controlled feasibility study to evaluate the clinical performance of RECELL for repigmentation of stable, depigmented lesions. The trial will evaluate 50 matched, stable depigmented areas from 10 subjects.

The study to compare the outcomes of mini punch grafting in patients with resistant stable non-segmental vitiligo already on narrowband ultraviolet B and receiving either no additional medication , systemic mini pulse (high and low dose) steroids, topical superpotent steroids once every other day , or daily tacrolimus ointment .in terms of the extent of repigmentation , frequency of reactivation and side effects.

Vitiligo is a chronic disease with an unpredictable clinical course, characterized by the appearance of white macules and patches on the skin and mucous membranes due to the disappearance of melanocytes in the affected area. It affects approximately 0.5% - 2% of the population worldwide and may occur at any age. Vitiligo is caused by a dynamic interplay between genetic and environmental risks that initiates an autoimmune attack on melanocytes in the skin.

Since abnormal keratinocyte (KC) proliferation and differentiation as well as defective E cadherin expression were reported in vitiligo lesions, the investigators set to study the potential efficacy of combining Retinoids, which are known to improve KC proliferation and differentiation and increase the expression of adhesion molecules, with narrowband UVB in the treatment of vitiligo.
