Filter by:The purpose of this study is to determine if topical ruxolitinib 1.5% will provide repigmentation in vitiligo lesions.
The purpose of this study is to investigate stress response pathways in tissues and melanocytes from patients with vitiligo. Investigators are collecting evidence of UPR and stress response activation in tissues and melanocytes from patients with vitiligo. Individuals with vitiligo will have punch biopsies to study stress response UPR activation and NF-κB signaling to test our hypothesis. In order to characterize differences between disease and normal states, a second arm of control individuals (Arm 2) will be recruited.
Principal objective: To compare the efficacy of laser-assisted dermabrasion + autologous epidermal cells suspension grafting versus dermabrasion using micro-needling technique + autologous epidermal cells suspension grafting and dermabrasion using micro-needling technique + placebo suspension grafting in stable vitiligo. A total of 10 patients with stable non-segmental vitiligo will be included in the ITT population. In each patient, three separate test areas will be selected in the same part of the body. One area will be pre-treated with dermaroller and receive the hyaluronic acid suspension alone and the two others will receive the epidermal cell suspension in hyaluronic acid after pre-treatment either with dermaroller or laser-assisted dermabrasion, each patient being his own control. Targeted phototherapy with excimer lamp (308 nMm) will be applied on all test areas 1 week after cell grafting.
Vitiligo is the most common acquired depigmented disorder of the skin characterized by destruction of melanocytes resulting in well-circumscribed achromic macules. Ultraviolet phototherapy with narrow band (UVB-NB) is currently one of the treatments of choice, because it is able to induce proliferation, differentiation, maturation and migration of melanocytes. This repigmentation has distinctive patterns such as follicular, marginal, and diffuse. The aim of this study is to observe the dynamics of migration and proliferation, in vitiligo patients under UVB radiation phototherapy treatment. The investigators will evaluate this process by measuring FAK (focal adhesion kinase ) and c-Kit by immunohistochemistry and reverse transcriptase polymerase chain reaction assay.
ORSHFS grafts yielded lower cell counts than NCECS but the M-K ratio and resultant repigmentation did not show significant difference with better healing of the donor site. Compared to cryoblebs, CO2 gave more homogenous pigmentation. The acral sites showed better results using combination of donor NCECS and recipient cryoblebs.
The objective of this study is to assess the effectiveness and safety of narrowband-ultraviolet B (NB-UVB) treatment in adult subjects with vitiligo.
Multicentric French parallel double-blind randomized versus placebo study
The purpose of this study is to assess the efficacy and safety of ReCell grafting after CO2 laser abrasion with superficial full surface ablation, fractional laser treatment and conventional (deep) full surface CO2 laser ablation, to assess the practical aspects and the patient reported outcome and to assess the cellular composition of the graft.
Condition: Non segmental and active vitiligo of adulthood. Main objective: To evaluate the efficacy of a daily treatment with atorvastatin 80mg/d combined to UVB compared to UVB alone in active vitiligo after 6 months of treatment. Methods: Prospective interventional bicentric study with evaluation blinded to the treatment received. Inclusion criteria: Patients from 18 to 75 year-old with active non segmental vitiligo. Active is defined by the apparition or the modification of vitiligo lesions with the past 3 months and under Wood's lamp examination hypochromic borders and/or spotty depigmentation. Interventions: After central randomization - Arm A : atorvastatin 40mg/d for 1 months then 80mg/d for 5 months combined with twice weekly narrowband UVB treatment for 6 months. - Arm B: with twice weekly narrowband UVB treatment for 6 months. Evaluation: Main criteria: Decrease of VASI score expressed in percentage Secondary criteria: Decrease of VETF score expressed in percentage. Variation of PGA and DLQI scores. Clinical and biological tolerance. Variation of CXCL10 levels in the serum. Length of the study: Inclusion period: 12 months. Length of treatment: 6 months. Statistical analyses and drafting the article: 6 months. Total length: 24 months.
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.
