Abstract

Abstract Hypoxia-inducible factor prolyl-hydroxylase inhibitors belong to a new class of orally administered drugs for treating anemia in patients with chronic kidney disease (CKD). The prevalence of hypothyroidism is disproportionately high in patients with CKD on hemodialysis. We report a rapid suppression of thyroid-stimulating hormone (TSH) and decrease in free triiodothyronine (T3) and free tetraiodothyronine levels after switching from darbepoetin alfa to roxadustat in a hemodialysis patient with hypothyroidism on levothyroxine therapy. This was reversed after stopping roxadustat. Roxadustat has structural similarity with T3 and is a selective activating ligand for thyroid hormone receptor-β possibly suppressing TSH release.
