Active clinical trials for "Vitiligo"

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 purpose of this study is to determine if vitiligo patients develop tolerance to ultraviolet light therapy, a type of treatment available for vitiligo.

The study series consists of three studies with the aim to assess the incidence, prevalence, risk factors, comorbidities and management of patients with alopecia areata in Czech Republic based on the patients and registry of a dermatology clinic of a metropolitan hospital.

Assessment of the level of JAK1 in both vitiligo and psoriasis patients before and after treatment with NB-UVB which is considered a gold standard therapy for both diseases.

This current three-year proposal aims to clarify the mechanisms of melanocyte destruction and regeneration in vitiligo lesions using both traditional cell culture and skin equivalent model (organotypic culture).

The skin microbiome has been implicated in several cutaneous autoimmune pathologies such as psoriasis and atopic dermatitis. However, its role in vitiligo and vitiligo lesions occuring in patients receiving anti-PD-1 for metastatic melanoma

Vitiligo is the most commonly acquired depigmentation disorder characterized by selective destruction of melanocytes resulting in well-circumscribed achromic macules. Tissue-resident memory T cells (TRM) are memory T lymphocyte subsets that reside in the skin, lack recirculation, proliferate locally, produce cytokines, and may be implicated in relapses. NB-UVB Phototherapy induces repigmentation in certain patterns. The aim of this study was to determine the levels of TRM cells on vitiligo lesions, and after phototherapy by repigmentation pattern.

This study aims to evaluate some differences in the immune system between patients with vitiligo and patients without the disease. These differences will be evaluated by the extraction of peripheral blood that will be analyzed before the treatment and after the treatment that, in the habitual way and at the discretion of the responsible dermatologist. Patients agreeing to participate in the study will be subjected to extraction of two tubes (20 ml) of peripheral blood (baseline) and after 12 weeks (+/- 5 days) of treatment. Therefore, neither treatment nor follow-up visits will be modified by participation, but will be the same whether or not participate in the study. In the case of controls, two peripheral blood tubes (20ml) will be removed in a single participation. Patients with vitiligo will also be asked to complete questionnaires to measure stress, depression and perception of disease (PSS-10, Skindex-29, HADS, Likert) before and after 12 weeks (+/- 5 days) of therapeutic intervention . This study will include 20 patients with active non-segmental vitiligo and 10 controls without the disease. The duration of participation in this study will be 12 weeks (+/- 5 days) for patients with vitiligo and a single participation (extraction of 20 ml of peripheral venous blood) for the controls.

The aim of this study is to establish whether the use of a special digital camera (SIAscopy) can provide an accurate and reliable measure of vitiligo which is at least equivalent to the current gold standard of planimetry. If so, SIAscopy could be used as an objective diagnostic and prognostic tool in the management of vitiligo patients within dermatology departments and allow a fair and accurate assessment of new potential treatments.

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.
