title: [Evaluation of the thyroid function in healthy aged patients residing in 2 geriatric institutions].
abstract: Thyroid function assessment in elderly inpatients. It is not well known whether normal ageing might lead to an impairment of thyroid function. We evaluated 297 elderly inmates in two geriatric institutions. After having excluded from the study those who were affected by chronic hepatic or renal disease, were under pharmacologic treatment or had suffered from acute ailments during the previous two months, we assessed thyroid function by determining circulating T4, T3, rT3, FT4, FT3 and TSH in 130 apparently healthy subjects. They could be divided into three groups composed of patients mentally competent, affected by either vascular or senile dementia, or affected by chronic psychosis. Results were also assessed with reference to three different age ranges (65-74, 75-84 and over 85 years). Two patients had subnormal thyroid hormone levels with elevated basal thyrotropin, while other two demonstrated only elevated thyrotropin levels, qualifying respectively for a diagnosis of primary hypothyroidism and subclinical hypothyroidism. In the remaining 126 patients thyroid function was normal, and no differences in thyroid hormone levels could be noticed among the various groups of patients, divided for sex, age range and mental condition. The results of our study confirm the presence of a high percentage of subclinical thyroid dysfunction in old age. They also suggest that in healthy aged subjects thyroid function parameters are not significantly different in reference to sex, age range and mental condition.
