OBJECTIVE Study of the function of the hypothalamus-pituitary-thyroid system in rheumatoid arthritis (RA) MATERIALS AND METHODS: Three hundred and fifty patients with RA of different forms, stages, and intensity were examined. The blood and synovial fluid (SF) levels of thyroid-stimulating hormone (TSH), thyroxine (T4) and triiodothyronine (T3) were measured by immunoradiometric assay. RESULTS Patients with RA were found to have higher T4 levels (in articular rheumatism, there was its negative correlation with the intensity of the process and in the presence of systemic manifestations of RA, there was a positive correlation). Blood T5 levels with higher RA intensity tended to increase in patients untreated with glucocorticosteroids. Blood TST concentrations showed an upward tendency which correlated with the intensity and stage of RA. Changes were also revealed in SF TST, T4, T3 levels. CONCLUSIONS The changes in the secretion of TSH, T4, T3 in patients with RA are caused by this pathological process and those in their SF levels affect the course of articular inflammation.

UI MeSH Term Description Entries
D007030 Hypothalamo-Hypophyseal System A collection of NEURONS, tracts of NERVE FIBERS, endocrine tissue, and blood vessels in the HYPOTHALAMUS and the PITUITARY GLAND. This hypothalamo-hypophyseal portal circulation provides the mechanism for hypothalamic neuroendocrine (HYPOTHALAMIC HORMONES) regulation of pituitary function and the release of various PITUITARY HORMONES into the systemic circulation to maintain HOMEOSTASIS.

D005938 Glucocorticoids A group of CORTICOSTEROIDS that affect carbohydrate metabolism (GLUCONEOGENESIS, liver glycogen deposition, elevation of BLOOD SUGAR), inhibit ADRENOCORTICOTROPIC HORMONE secretion, and possess pronounced anti-inflammatory activity. They also play a role in fat and protein metabolism, maintenance of arterial blood pressure, alteration of the connective tissue response to injury, reduction in the number of circulating lymphocytes, and functioning of the central nervous system.

D001172 Arthritis, Rheumatoid A chronic systemic disease, primarily of the joints, marked by inflammatory changes in the synovial membranes and articular structures, widespread fibrinoid degeneration of the collagen fibers in mesenchymal tissues, and by atrophy and rarefaction of bony structures.
