Thyroid hormones play an essential part in human metabolism.1 Thyroid hormones support anabolism, intricate in cardiovascular system function (increase heart contractility and cardiac output), and reduce triiodothyronine/reverse triiodothyronine (T3/rT3) ratio, which frequently relates to normal or low thyroid stimulating hormone (TSH) and thyroxine (T4) levels.2 Euthyroid sick syndrome (ESS) is considered when patients with non-thyroidal illness (NTI) demonstrate abnormal thyroid function.2 Among intensive care unit (ICU) patients, ESS or low-T3 syndrome is more common than true hypothyroidism.3,4 A variety of changes in critically ill patients have been observed, including low T3 levels, followed by low T4 and TSH levels.

ESS can be described as abnormal thyroid function test results that occur in the setting of a non-thyroidal illness and in the absence of pre-existing hypothalamo-pituitary and thyroid gland dysfunction.
Non-thyroidal illness syndrome is a manifestation of hypothalamicpituitary dysfunction, and in view of current evidence, should be treated with appropriate replacement therapies.

"The main problem is to differentiate between dogs with primary hypothyroidism and dogs with non-thyroidal illness," says Dr.
TSH concentrations within the reference range, we have shown that our new test completely differentiates between the two groups--otherwise proven primary hypothyroidism or non-thyroidal illness."

Physiological changes in thyroid function associated with ageing (7) and effects of non-thyroidal illness and drugs make interpretation of thyroid function tests in elderly people difficult (8).
These include resistance to thyroid hormone [30], change in the dopamine regulation of TSH secondary to ageing [31], use of drugs [32], pituitary dysfunction in severe non-thyroidal illnesses [33], or undernutrition.
Heterogeneity of populations, differences in incidence of lymphocytic thyroiditis, the influence of non-thyroidal illnesses, the use of drugs that alter thyroid hormone metabolism and the level of iodine content of the diet may explain the wide range of [TABULAR DATA FOR TABLE IV OMITTED] prevalence of increased TSH levels in the elderly populations [37].
However, in routine clinical practice there are more cases with border line elevations of TSH with normal T4 and T3, where the etiology could not be explained alone by non-thyroidal illnesses (NTI), medications, age or simply a variation of normality.3,4
