ROSENFARB, Johanna; FAINGOLD, M. Cristina  e  BRENTA, Gabriela. Non-thyroidal illness. Rev. argent. endocrinol. metab. [online]. 2017, vol.54, n.2, pp.83-91. ISSN 1851-3034.

Non-thyroidal illness is a disorder that occurs frequently in patients that are experiencing some kind of illness, whether critical or not. It can manifest even in the absence of thyroid dysfunction, leading to changes in the thyroid axis. It is important to detect Non-Thyroidal Illness in order to establish a differential diagnosis with the true thyroid disease and to determine whether treatment is required. Currently, there is still no consensus on whether Non-Thyroidal Illness is a physiological response to a systemic disease to reduce energy requirements or whether it is an adaptive condition that induces a hypothyroid state that ultimately is harmful at the tissue level.

Palavras-chave : Non-thyroidal illness; Thyroid axis; Thyroid hormones.
