Background: Vitiligo is a chronic immune-mediated inflammatory skin disease, it is a disorder of both the innate and adaptive immune system. Objectives: The aim of this work was to evaluate serum level of granulysin in vitiligo patients. Methods: This case control study included 30 patients suffering from vitiligo. In addition, 20 apparently healthy individuals. Measurement of serum granulysin using enzyme-linked immunosorbent assay was performed in all subjects. Results: When compared to the control group, the vitiligo group had significantly higher serum granulysin levels (P< 0.02). Conclusions: Granulysin levels in the blood may contribute to the pathogenesis of vitiligo.
