Rescue of Graves Thyrotoxicosis-Induced Cholestatic Liver Disease Without Antithyroid Drugs: A Case Report

Abstract

Graves thyrotoxicosis rarely presents with painless jaundice resulting from hyperthyroidism-associated hepatotoxicity, without preexisting liver disease. Management in patients with this presentation is challenging, given that the thionamides, methimazole and propylthiouracil, have both been associated with drug-induced liver injury. Radioactive iodine ablation and thyroidectomy are well-established alternatives, but each have their associated risks and contraindications. We present an unusual case of severe hyperthyroidism-associated hepatotoxicity, in which adjuvant therapies, including glucocorticoids, saturated solution of potassium iodide, and cholestyramine, were used as a bridge to definitive therapy with thyroidectomy.
