Evaluation of thyroid functions in leprosy. I. Thyroid function tests.

Twenty six patients of different types of leprosy were studied for radio active iodine uptake (I131) and serum levels of triiodothyronine (T3), thyroxine (T4) and thyroid stimulating hormone (TSH). None of the patients had clinical evidence of thyroid involvement. No significant difference was found between the values obtained in patients and normals and in different varieties of leprosy.

Thyroid disease and abnormal thyroid function tests in women with eating disorders and depression.

Forty-two female patients with an eating disorder and major depression were compared with 48 female patients with major depression in a retrospective chart study for the prevalence of thyroid disease and laboratory thyroid function abnormalities in the absence of thyroid disease. Eating disorder patients, aged 30-80 years, had a significantly higher incidence in thyroid diseases (53%) then those with major depression alone (17%). The incidence of thyroid disease did not differ between the two groups among patients aged 11-29 years. Abnormal thyroid screening values occurred in 40% of euthyroid eating disorder patients and 34% of those with major depression. While the overall prevalence of thyroid disease in depressed females (15%) was similar to that in the general population (10.5%), thyroid disease in the eating disordered/depressed patients was twice the rate expected (24%) in the general population. Female patients who require psychiatric hospitalization should be routinely evaluated for thyroid function, especially those diagnosed with an eating disorder and depression.

Effect of antidepressant medication on morning and evening thyroid function tests during a major depressive episode.

BACKGROUND: This study sought to determine whether changes in thyroid function that may occur during antidepressant treatment are related to a direct effect of the drug on the thyroid axis or to a change in clinical state. METHODS: Morning and evening thyroid function was evaluated in 30 euthyroid inpatients who met DSM-IV criteria for major depressive episode, by determination of free triiodothyronine, free thyroxine, and thyrotropin levels before and after 8 AM and 11 PM protirelin challenges (200 micrograms intravenously), on the same day. Results at baseline were compared with those after 1 month of antidepressant treatment with either amitriptyline hydrochloride, fluoxetine hydrochloride, or toloxatone. RESULTS: Clinical efficacy and effects on thyroid function did not differ across the 3 antidepressant drugs. Compared with pretreatment values, significant reductions in basal serum 8 AM free thyroxine, 11 PM free thyroxine, and 8 AM free triiodothyronine levels and increases in 11 PM maximum increment in plasma thyrotropin level and the difference between 11 PM and 8 AM maximum increment in plasma thyrotropin values were observed in responders (n = 11) but not in partial responders (n = 6) or nonresponders (n = 13). Moreover, nonresponders exhibited lower pretreatment 11 PM thyrotropin values (basal and maximal increment above basal) than responders. CONCLUSIONS: The results suggest that (1) changes in thyroid function are related to clinical recovery rather than to a direct effect of the antidepressant drug and (2) patients with the lowest pretreatment evening thyrotropin secretion have the lowest rate of antidepressant response, and this may contribute to treatment resistance.
