Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
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.
