It is a study of translational research with mechanistically objectives and including biological samples of patients with chronic inflammatory disorders
This study was a single-center prospective study to collect blood and skin tissue at the time of consultation with a patient with non-segmental vitiligo, psoriasis, atopic dermatitis or alopecia areata, in order to better understand and compare blood and skin immune response in chronic inflammatory skin disorders: psoriasis, alopecia areata, atopic dermatitis and vitiligo.
343 studies on the registry are indexed under Vitiligo; 96 are open to participants now.
This study's planned enrollment of 450 is above the median of 114 across 67 observational studies indexed under Vitiligo.
