Thyroid Hormones in ADPKD

Brief summary (registry, in English)

Autosomal dominant polycystic kidney disease (ADPKD) is a monogenic, rare and life-threatening disease, characterized by the pathological formation of multiple fluid-filled cysts that arise from renal tubules and alter kidney architecture and function. In most patients, the progressive deterioration of renal function ultimately leads to end-stage kidney disease (ESKD) and the need for dialysis or kidney transplantation. Save the conventional anti-hypertensive strategies, there are currently two disease-specific treatments for ADPKD (Tolvaptan and Octreotide-LAR). However, these drugs are only available to patients at high risk of progression to ESKD, while a remarkable number of ADPKD patients progress to ESKD despite the treatments. Cyst formation in ADPKD is determined by mutations in two genes encoding two transmembrane proteins: polycystin1 and polycystin2. The pathogenesis of the disease involves a series of phenotypic alterations, including the de-differentiation of epithelial cells, uncontrolled proliferation and abnormal secretion of fluids in the cysts, metabolic remodeling, all phenomena that lead to the progressive loss of renal structure and function . Therefore, to try to investigate the mechanisms of the disease, the investigators should go in search of pleiotropic molecules capable of simultaneously modulating structure, function and metabolism. Research done so far suggests that thyroid hormones (TH) may also act as pleiotropic modulators in the patho-biology of ADPKD. TH signals play a crucial role in the regulation of cell de-differentiation and cell cycle reactivation, as well as in the metabolism and evolution of cardiac and renal diseases. Interestingly, changes in TH levels have been detected in approximately 80% of patients with chronic renal failure (CKD), whereas patients with ADPKD show a higher incidence of clinical and subclinical hypothyroidism. Despite these evidences, the ability of TH to modulate anti-cystogenic and renoprotective processes in ADPKD has not yet been studied. The objective of this study is to determine the levels of THs in the serum of ADPKD patients with normal renal function and mild, moderate or severe renal dysfunction, and to correlate them with renal functional parameters.
