[Clinical and Pathophysiological Aspects of the Interactions Between the Thyroid and the Kidney].

Chronic kidney disease (CKD) is a multifactorial clinical condition consisting of a complex set of manifestations that, in addition to renal involvement, involve multiple organ systems. Endocrine disorders are particularly common in patients with CKD and require proper management given their multisystemic effects. The main endocrine disorder found in patients with kidney disease is alterations in the calcium-phosphorus (PTH) axis, which is why nephrologists often focus exclusively on managing this condition, neglecting any other endocrine alterations observed in this patient group. Thyroid involvement appears worthy of attention both in terms of its numerical frequency and therapeutic implications. The aim of this review is to enable a proper assessment of thyroid disease in patients with kidney disease and to provide the tools for appropriate assessment and treatment.
