Filter by:The purpose of this study is to investigate the efficacy and safety of autologous transplantation of melanocytes in patients with vitiligo.
To assess over a 25-week period the efficacy of hand-foot narrow-band ultraviolet B light versus focal 308-nm light treatment in inducing the return of pigment in vitiligo after skin minigraft transplants to the backs of the hands in patients with light brown to black skin. Subject will undergo treatment for 13 weeks.
The effect of treatment with narrow-band UVB 311 nm after transplantation of harvested autologous epidermal cells on vitiligo lesions will be investigated.
Background Phototherapy UVB TL01 currently represents the first choice in treatment to induce the repigmentation of vitiligo spots. The problem though is that there are no systems or scales which enable an objective evaluation of the therapy, commonly known as percentage of repigmentation. Recently, a European Task Force (VETF, Vitiligo European Task Force) of experts on vitiligo, within the European Society of Pigmentation, has proposed a gravity classification on the basis of three parameters/standards - extension, progression and the level of depigmentation - and used to classify patients in ten European centres. The aim of the trial is to validate the VETF scoring system set up in relation with the therapeutic answer to the standard treatment for vitiligo and phototherapy. Leaving aside short term side effects, such as sunrush/erythema and sunburn, which are reversible and infrequent, the main problem with phototherapy is represented by the cumulative long term effects of ultraviolet rays. These can cause premature ageing of the skin (photoaging) and the appearance of skin cancer/neoplasia. Therefore the aim is to get the best results from phototherapy whilst limiting its length. Aims of the trial: 1. To validate the VETF scoring system. As phototherapy is currently the only universally accepted treatment for vitiligo, it seems logical to test the VETF scoring system first to evaluate the effectiveness of phototherapy. 2. Secondly, the target of this multicentric trial is to compare the effectiveness of two different phototherapy protocols; a first protocol foresees non-stop treatment for 6 months; a second protocol foresees periods of interruption during the treatment. This will help to verify whether interrupting a cycle of phototherapy is useful or not. This interruption might make the ultraviolet rays more effective 'stimulus on the melanocytes', and may also reduce long term damage caused by phototherapy.
The aim of this study is to survey melanocytes in the ability of self-assembly on biomaterials and functional analysis in vitro. Also, this study may provide a better way for treatment of vitiligo after understanding the functional aspects of melanocytes.
The purpose of this study is to determine wether vitiligo patients have more audiological abmnormalities, than the healthy population.
The study offers narrowband UVB light therapy to patients who have 5% of their body involved with vitiligo. The hypothesis is that Narrowband UVB promotes melanocyte proliferation in vitiligo lesions.
The purpose of this study is to determine whether bath PUVA are effective in treatment of vitiligo and what is the complication of bath PUVA in vitiligo.
Patients with vitiligo vulgaris are treated with Pimecrolimus twice a day during 6 months. After a baseline visit, patient returns for a control visit after 3 and 6 months of treatment. One reference lesion is clinically evaluated with pictures.
To determine the optimal treatment frequency of 308-nm excimer laser for vitiligo and identify the key clinical variable(s) associated with the treatment efficiency under the optimal treatment frequency. Prospective, randomized, comparative study among groups of vitiligo patients treated with 308-nm excimer laser, with the limitation of no follow-up.
