'Low T3 syndrome' in patients chronically treated with an iodine-containing drug, amiodarone.

Cardiac patients treated with the iodine-containing drug 'amiodarone' undergo a significant iodine overload which can last for months after the drug has been withdrawn. Some patients develop hyperthyroidism and others hypothyroidism. In the hyper- or hypothyroid patients, the indices of thyroid function are modified as usually observed in these situations. In the patients remaining euthyroid while taking amiodarone or after its withdrawal, but still under its influence as shown by the iodine overload, a 'low-T3 syndrome' is observed, this state being characterized by a high total T4, a low free T4, a normal T3 resin uptake, a low total T3, a normal free T3, a high r-T3 and a relative TSH-unresponsiveness to TRH.

[Amiodarone and thyroid function].

Amiodarone is a drug which is frequently used in cardiology, and which can lead to the appearance of hyper- of hypo-thyroidism in certain cases. A study of the various parameters of thyroid function has shown that these are abnormal in every case treated by this drug, without the biochemical abnormalities necessarily being reflected clinically. The authors outline a method which will allow a distinction to be drawn between patients with a true thyroid malfunction and those whose biochemical results do not appear at first sight to be of any consequence. Regular assays of the T3RIA level are suggested as a means of early detection of thyroid malfunction in patients undergoing treatment with amiodarone.
