What is the Origin of Thyroid Resistance?

The term combines "thyroid," referring to the hormone-producing gland, with "resistance," denoting the failure to respond effectively to a stimulus. The formal syndrome name, RTH, was coined upon the discovery of the underlying genetic defects in the thyroid hormone receptor.

What is the Mechanism of Thyroid Resistance?

The primary mechanism of thyroid resistance involves a genetic mutation in the thyroid hormone receptor (TR) gene, usually TR-beta. This mutation impairs the receptor's ability to bind T3 or to properly regulate gene transcription upon binding. Consequently, despite adequate or high circulating hormone levels, the target cell cannot execute the thyroid hormone's intended metabolic and regulatory functions. The degree of resistance varies by tissue, leading to the heterogeneous clinical presentation.

Thyroid Resistance

Meaning

Thyroid Resistance, also formally known as Resistance to Thyroid Hormone (RTH), is a rare clinical syndrome characterized by a reduced responsiveness of target tissues to the circulating thyroid hormones, thyroxine (T4) and triiodothyronine (T3). This condition typically results in elevated levels of both thyroid hormones and Thyroid-Stimulating Hormone (TSH), as the pituitary gland attempts to overcome the cellular resistance. Clinically, patients may present with a mix of hypothyroid and euthyroid symptoms due to varying degrees of tissue-specific resistance. This diagnosis requires careful differentiation from common forms of hypothyroidism and is essential for appropriate therapeutic management.
