title: [Pathology of thyroid hormone receptors].
abstract: The syndrome of resistance to thyroid hormones may affect overall or only some tissues. The generalized resistance associates a familial eu or hypometabolic goiter, increased free thyroid hormones with normal or elevated plasma TSH levels. The inheritance of the disease is autosomal dominant in most of the patients. In vivo or in vitro tests may be used to assess the diagnosis. Therapy refers to high doses of T3 or T4. Pituitary resistance to thyroid hormones leads to hyperthyroidism with normal or high TSH levels. The treatment uses different TSH suppressive drugs. Peripheral resistance associates hypometabolism with normal T4-T3 secretion and needs high T3 doses for therapy. An inherited abnormality of T3 nuclear receptor seems to be the consequence of a mutant gene. Hypersensitivity to thyroid hormones associates hypermetabolism with low or normal free thyroid hormone levels and increased T3 nuclear receptors.
