Thyroid and Pseudothyroid Dysfunction as a Cause That is Promoting the Relapse of Benign Focal Thyroid Pathology.

Several studies deal with learning causes stipulating nodular formations in the thyroid tissue, including those occurring against the ground of metabolic disorders of thyroid hormones. Our study's objective was to determine the peculiarities of thyroid homeostasis disorders in patients suffering from benign nodular thyroid pathology with relapses of the disease and its relapse-free course. For this purpose, 96 female patients suffering from nodular thyroid pathology and 20 without thyroid pathology were examined. In the course of the study, the following were found in patients with benign focal thyroid pathology: disorders of the peripheral conversion of the thyroid hormones, compensatory activation of the hypothalamic-pituitary system evident in increased levels of the thyroid-stimulating hormone, ТSH/fT3 and ТSH/fT4 ratios, increasing titers of the anti-thyroid antibodies which can be hazardous for the risk of development of nodules or reflects the process of thyroid tissue damage; high level of thyroglobulin caused by an increased probability of relapse and rate of nodule growth, an increase of the thyroid gland volume associated with activation of the hypothalamic-pituitary system, increased antibodies titer and thyroid gland damage. Thus, changes of the examined indices in the blood can be used as prognostic markers concerning the relapse of nodule formation in the thyroid tissue.
