Abstract
Background: Vitiligo is a skin disorder characterized by the loss of melanocytes from the epidermis. Cysteine x cysteine motif chemokine ligand 10 (CXCL10) is linked to the Th1 pattern and has been suggested as one of the most relevant chemokine axes that promote T-cell migration in different autoimmune and inflammatory processes. The aim of this study was to assess the immunohistochemical (IHC) expression of CXCL 10 in skin lesions of patients with vitiligo to explore its possible role in the pathogenesis of the disease.
Methods: In this prospective, case-control study, we examined biopsies from the lesional skin of 20 patients with vitiligo for IHC expression of CXCL 10: 10 patients presented with stable nonsegmental vitiligo (group A), 10 patients presented with active nonsegmental vitiligo (group B), and 10 apparently healthy volunteers were examined as controls (group C).
Results: Nine patients in group A had mild IHC expression of CXCL 10 (+1) and 1 patient had moderate expression (+2). In group B, 8 patients had strong expression of CXCL 10 (+3), and the remaining patients had moderate expression (+2). However, there was no expression of CXCL 10 in all skin specimens in the control group.
Conclusions: CXCL10 IHC expression was increased in vitiligo lesions indicating a possible role in the pathogenesis of disease. The expression was significantly increased in active vitiligo compared with stable vitiligo.
