TPO and vitiligo: A recent meta-analysis of 37 studies with 78,714 vitiligo patients showed that in all patients with vitiligo, the prevalence of TD, ATD, thyroid peroxidase antibodies (TPOAbs), and thyroglobulin antibodies (TGAbs) was 15.7, 1.9, 16.8, and 11.4%, respectively, which was significantly higher than that in healthy controls (40).
