Filter by:Vitiligo affects 0.5 to 2% of worldwide population and has a demonstrated impact on the quality of life. Optimal treatment of vitiligo requires to target the auto-immune inflammatory response (to halt the depigmentation process), but also to induce the differentiation of melanocyte stem cells (to induce repigmentation). There is a well demonstrated discrepancy in the repigmentation response between anatomical areas of the body. Face and neck are the best responder with complete or almost complete repigmentation achieved in most cases under treatment. Trunk and limbs could have a complete or almost complete repigmentation in approximately half of the cases. The repigmentation is much more difficult in wrists, elbows, knees, proximal part of the hands. Finally, some areas such as the extremities of hands and feet, palms, soles, are almost impossible to repigment. The investigator hypothesize that there are some factors that are produced in the skin that prevent (or at least decrease) the differentiation but also probably the migration and proliferation of melanocytes. Primary objective To compare the mRNA expression of each types of cells in the skin of vitiligo patients compared to healthy volunteers according to body locations
Vitiligo is a auto immune that impact 2% of the global population, regardless from the phototype. Even though it affects patients in a physical way through loss of pigmentation, it is also impacting them on a mental/emotional way.11-12 Current treatments offer a symptomatic solution to patients, however the response rate can be low and results can be slow. Pediatric patients in vitiligo deserves special care as frequently (50%), the disease onset is before 20 years of age and, in 25% of the cases, it starts before the age of 10 years.13 Also, the current treatments for children are limited since it can involve pain and claustrophobia. The combination therapy of the study could offer a painless and easy treatment to follow. If the combination of those two therapies can fasten and improve the response rate, this could be a good option to treat this condition not only in children, but also for adults patients.
The goal of this pilot clinical trial is to assess the effectiveness of psychodramatic psychotherapy in reducing the psychological distress and/or the skin condition in patients with vitiligo. The main questions it aims to answer are: 1. Is there any improvement in terms of psychological distress in patients with vitiligo participating in a psychodramatic psychotherapy, compared to a control group? 2. Is there any improvement in terms of skin condition in patients with vitiligo participating in a psychodramatic psychotherapy, compared to a control group? Participants in the experimental group will receive the dermatological drug treatment usually recommended for vitiligo, and in addition they will participate in a 6 months psychodramatic psychotherapy. Researchers will compare the results of the experimental group with the results of a control group including vitiligo patients who will receive the dermatological pharmacological treatment usually recommended for vitiligo and participate in a 6 months program of self-help activities.
Vitiligo is characterized by the selective loss of melanocytes, which in turn leads to totally amelanotic, non-scaly, chalky-white macule with distinct margins Vitiligo is the most common depigmenting skin disorder, with an estimated prevalence of 0.5-2% of the population in both adults and children worldwide Tumor necrosis factor (TNF-α), a pro-inflammatory cytokine is necessary for Th1 mediated response and immune homeostasis and the up-regulation of TNF-α can result in chronic inflammatory and autoimmune diseases . previous studies revealed a rise in transcript and protein levels of TNF-α in vitiligo patients The prime location of melanocytes, keratinocytes and fibroblasts is the epidermal microenvironment and these cells are capable of TNF-α expression and secretion TNF-α acts as an autocrine as well as a paracrine manner to suppress the melanocyte growth and proliferation ( Tristetraprolin (TTP) zinc finger protein 36 (ZFP36) is Ribonucleic acid (RNA) binding protein that preferentially binds to Adenylate-uridylate-rich (AU-rich) regions in the 3' untranslated regions (3'UTR) of target genes . Additionally, Tristetraprolin functions by destabilizing mRNAs encoding for oncogenes, cytokines (as TNFα), and chemokines involved in the inflammatory processes, by favoring their degradation and/or preventing their efficient translation The expression of proinflammatory mediator genes is tightly controlled by post-transcriptional regulation, which is mediated by a set of immune-related RNA binding proteins, such as tristetraprolin, Roquin, and Regnase
The aim of this observational study is to evaluate the level of the IL-35 protein in tissue biopsy from patients with active & stable vitiligo.
To evaluate repigmentation and quality of life after treatment of stable vitiligo lesions using the RECELL Device.
The goal of this observational study is to compare serum glucose and lipid metabolism levels between health volunteers and vitiligo patients. The main question it aims to answer is whether vitiligo is related to glucose and lipid metabolism disorders. Participants will complete a vitiligo questionnaire and test serum levels of indicators related to glucose and lipid metabolism. Researchers will compare vitiligo patients with healthy volunteers to see if there is a correlation between vitiligo and disorders of glucose and lipid metabolism.
The study aims to evaluate the safety and efficacy of the combination of topical baricitinib and 308-nm monochromatic excimer light versus 308-nm monochromatic excimer light alone in treatment of non-segmental vitiligo.
The purpose of this study is to perform an in-depth analysis of the molecular pathways involved in lesions responding to current treatment and lesions not responding to current treatment
The purpose of this phase 2 study is to evaluate the effect and the safety of the combination of ANIFROLUMAB in combination with phototherapy in adult participants with non-segmental progressive vitiligo
