Suppression of the Secretion of Thyroid Stimulating Hormone by Endogenous Triiodothyronine and Thyroxine: an Observation on a Patient of Chronic Thyroiditis Treated with Corticosteroid

Abstract

Administration of prednisolone, 30mg per day, for a month followed by its alternate-day administration was very effective to restore the thyroid function and clinical symptoms in a rare case of hypothyroidism caused by chronic thyroiditis with inflammatory symptoms. Decreased serum T₃ and T₄ in this patient were increased to normal values by the administration of prednisolone and increased serum TSH became undetectable.
