Non-Thyroidal Illness: Physiopathology and Clinical Implications
In critical illness, several abnormalities in thyroid hormone (TH) secretion, metabolism and action have been described in patients without previous diagnosis of intrinsic thyroid disease and are collectively called “Non thyroidal syndrome” (NTIS) [1]; this term is now largely employed, in the place of “euthyroid sick syndrome” [2-4] or “low-T3 syndrome”, due to the most common abnormality, a d...
متن کاملThe molecular basis of the non-thyroidal illness syndrome.
The 'sick euthyroid syndrome' or 'non-thyroidal illness syndrome' (NTIS) occurs in a large proportion of hospitalized patients and comprises a variety of alterations in the hypothalamus-pituitary-thyroid (HPT) axis that are observed during illness. One of the hallmarks of NTIS is decreased thyroid hormone (TH) serum concentrations, often viewed as an adaptive mechanism to save energy. Downregul...
متن کاملMechanisms behind the non-thyroidal illness syndrome: an update.
The mechanisms behind the changes in serum triiodothyronine (T(3)), thyroxine (T(4)) and TSH that occur in the non-thyroidal illness syndrome (NTIS) are becoming clearer. Induction of a central hypothyroidism occurs due to a diminution in hypothalamic thyrotropin-releasing hormone. This can be signalled by a decrease in leptin caused by malnutrition and possibly a localised increase in hypothal...
متن کاملNew Insights toward the Acute Non-Thyroidal Illness Syndrome
The non-thyroidal illness syndrome (NTIS) refers to changes in serum thyroid hormone levels observed in critically ill patients in the absence of hypothalamic-pituitary-thyroid primary dysfunction. Affected individuals have low T3, elevated rT3, and inappropriately normal TSH levels. The pathophysiological mechanisms are poorly understood but the acute and chronic changes in pituitary-thyroid f...
متن کاملNon-thyroidal illness syndrome and cardiopulmonary bypass in children with congenital heart disease
Abstract Background: The thyroid hormones influence on all metabolic pathways. After heart surgery using cardiopulmonary bypass (CPB), serum T3 decreases and remains low for at least 24 hours. Several studies on pediatric have reported reduction of thyroid hormones after heart surgery. This study aimed to investigate the status of thyroid function tests in children with CPB surgery. Metho...
