Vitiligo is an acquired depigmentation disorder characterized by the loss of functional melanocytes from the epidermis. Two major theories of vitiligo pathogenesis include autoimmunity and oxidative stress‐mediated toxicity in melanocytes. The present study aimed to evaluate both the hypotheses in vitiligo patients and to investigate their role in the disease onset and progression. Antimelanocyte antibody levels and lipid peroxidation ( LPO ) levels were evaluated in 427 patients and 440 controls; antithyroid peroxidase ( TPO ) antibody levels were estimated in 102 patients and 72 controls. Patients showed a significant increase in LPO and antimelanocyte antibody levels compared to controls. Antimelanocyte antibody and LPO levels were higher in active vitiligo compared to stable. Only 9.8% of patients showed the presence of anti‐ TPO antibodies in their circulation. Oxidative stress may be the initial triggering event to precipitate vitiligo in G ujarat population, which is exacerbated by contributing autoimmune factors together with oxidative stress.
