[The predictive value of thyroid function in patients with respiratory tuberculosis].
Enzyme immunoassay was used to determine the levels of thyrotropric hormone (TTH), total and free fractions of thyroxine, and triiodothyronine in patients with respiratory tuberculosis. 61.8% of the patients were found to have type 3 euthyroid pathology that was characterized by the elevated levels of thyroxine and triiodothyronine with the unchanged level of TTH and by the absence of clinical manifestations of thyrotoxicosis. The levels of the total and free fractions of triiodothyronine and thyroxine were higher in patients with lung destruction, dissemination, or bacterial isolation than in those without these manifestations. The positive clinical and X-ray changes were followed up by regression of thyroid shifts in patients with the baseline high values of thyroid hormones. Antituberculous drugs did not affect thyroid function.
