Filter by:There are several surgical methods to treat vitiligo patches, and follicular unit extraction (FUE) is one among them. FUE, performed using punch biopsy extraction and hair follicle transplantation, has proven safe and effective in multiple studies for treatment of hair bearing (non-glabrous) skin. This technique has not yet been trialed on hairless areas (glabrous skin) affected by vitiligo, such as the lips, fingertips, knuckles, wrists, and feet, which tend to be resistant to standard treatments. We suspect this technique will be successful in patients who have responded well to other therapies in all areas except for non-hair bearing areas.
Rationale: Vitiligo is a common skin disorder that can impair a patient's quality of life. Many depigmented lesions in vitiligo patients remain therapy resistant for medical treatment. Therefore new therapeutic options in these patients are necessary. Currently, dermabrasion by conventional or fractional laser therapy in combination with NB-UVB therapy and steroids appears to be effective in therapy resistant areas. However, little literature on this combination is available. Objectives: To assess the efficacy and patient safety of (1)fractional CO2-laser treatment in combination with NB- UVB,(2) fractional CO2-laser treatment in combination with NB- UVB and topical corticosteroids versus NB-UVB treatment alone(3) Study design: Prospective observer blinded randomised intra-patient controlled study. Study population: 23 patients ≥ 18 years with non segmental vitiligo who receive NB-UVB treatment at the Netherlands Institute for Pigment Disorders (SNIP) at the Academic Medical Centre University of Amsterdam. We will include patients with 3 depigmented lesions that are resistant to NB- UVB treatment after 3 to 6 months. Methods: Three NB-UVB resistant depigmented regions on the trunk or extremities will be randomly allocated to;(1) NB-UVB treatment in combination with fractional CO2 laser abrasion, or (2) NB-UVB treatment in combination with fractional CO2 laser abrasion and topical steroids, or (3) NB-UVB treatment alone. NB-UVB treatment and topical steroids will be given according to the standard treatment protocol of the SNIP and continued for at least 6 months. Two and 6 months after the laser treatment, the percentage of repigmentation of the lesions will be assessed.
Previous studies have evaluated the transplantation of pigment cells (melanocytes)and skin cells (keratinocytes) for the treatment of vitiligo. This procedure is known as MKTP (Melanocyte Keratinocyte Transplantation Procedure). Multiple studies have found this procedure to be both safe and effective for the treatment of vitiligo. The majority of these studies utilized trypsin to help isolate melanocytes and keratinocytes. Trypsin is enzyme that helps to separate the different layers of skin. However, some cell biologists believe that the enzyme dispase (which can be used to separate the epidermis from the dermis) is less toxic to cells of the epidermis and can result in a greater number of viable melanocytes and keratinocytes for transplantation. This study will look at the repigmentation rates of MKTP using trypsin to isolate cells, versus MKTP using dispase to isolate cells.
This is a multicenter clinical trial, phase III, randomized, placebo-controlled, parallel group, enroll 94 patients, to assess the efficacy of ACH24 in the repigmentation of achromatic areas in patients with vitiligo.
Vitiligo is an acquired depigmentation disorder of great cosmetic importance, affecting 1-4% of the world's population. Phototherapy and topical agents such as corticosteroids, calcineurin inhibitors, and vitamin-D derivatives are basic treatment modalities have been used in vitiligo but there is still no effective and safe treatment for this disease. Resistance to therapy, treatment complications and recurrence after treatment are the major problems of the current treatments. There are no clinical studies of use of Bimatoprost in treatment of vitiligo, as it is supposed to cause more hyperpigmentation and hypertrichosis as compared to other topical prostaglandin analogues; hence, the investigators decided to use it in treatment of localized vitiligo.
