In another study, associations between vitiligo and anti-TPO (25.6%), anti-thyroglobulin (23.4%), antinuclear (16.8%), and anti-parietal cell (7.8%) antibodies were identified, noting that a total of 74 of the patients had autoimmune comorbidities (41.5%), mainly autoimmune thyroiditis [28]. Here, TPO is linked to autoimmune thyroid disease.
