Masked hyperthyroidism in a haemodialysis patient successfully treated by potassium iodide

摘要

Hyperthyroidism should be suspected in end-stage renal disease (ESRD) patients who exhibit signs and symptoms including weight loss, tremor, palpitation or atrial fibrillation (Af) [1-5]. This report presents the case of an 82-year-old Japanese female on maintenance haemodialysis (HD) and paroxysmal Af (pAf). Although the serum thyroid hormone levels were within normal reference values for a young healthy control, she was found to have masked hyperthyroidism.
