Abstract
Iodine and thyroid function are closely linked, since the only known role of iodine is its participation in the synthesis of thyroid hormones. Iodine metabolism may be represented as a metabolic cycle consisting of three main pools: the Plasma Inorganic Iodine (PIl) pool into which dietary iodine goes and from where it is either taken up by the thyroid or excreted by the kidneys, the intrathyroidal iodine pool, where. thyroid hormone synthesis occurs, and finally the peripheral pool of thyroid hormones, of which about 80% are deiodinated and 20% excreted with the faeces. Endemic goitre is usually due to iodine deficiency. There is no renal homeostatic mechanism to keep the PII level constant, and so adaptation to iodine deficiency occurs by increasing the thyroidal iodide clearance rate. Stable iodine measurements are necessary for a complete study of iodine metabolism. Estimates of the serum Protein-Bound Iodine (PBl) are the best index of thyroid function, estimates of the PII and of the urinary iodine are the best indices of iodine nutrition. (author)
