Thyroid antibodies (TA) are reported in five to 15% of people, with a higher prevalence in elderly females [1,2]. Thyroid peroxidase antibodies (TPO-Ab) were noted in more than 80% of cases, thyroglobulin antibodies (TGA) in >50% of cases, and thyroid-stimulating hormone receptor (TSHR) antibodies in 10% of cases with Hashimoto’s thyroiditis. Here, TSHR is linked to Takayasu arteritis.
