Understanding thyroid hormone action defects

Advancing Understanding, Diagnosis and Monitoring of Thyroid Hormone Action Defects (ADAM-THAD)

Istituto Auxologico Italiano · NCT06307990

This study is trying to learn more about how thyroid hormone problems affect the brain and heart in newborns and patients with unexplained symptoms, to help with early diagnosis and better monitoring.

What this trial studies

This observational study aims to investigate the neurological and cardiological features of patients with resistance to thyroid hormone syndromes, specifically focusing on the genetic variants affecting thyroid hormone receptors. It seeks to define the frequency of these syndromes, improve early diagnosis, and develop monitoring tools through biochemical and genetic investigations. Participants will include newborns and patients with unexplained neuro-cognitive or cardiovascular symptoms, and pluripotent stem cells will be generated for in vitro studies to explore the underlying molecular mechanisms. The study will correlate clinical data with laboratory findings to enhance understanding of these rare conditions.

Who should consider this trial

Good fit: Ideal candidates include newborns with biochemical signatures suggestive of thyroid hormone resistance or individuals with known diagnoses of these syndromes.

Not a fit: Patients without biochemical or symptomatic evidence of thyroid hormone resistance will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to earlier diagnosis and better management of thyroid hormone resistance syndromes, potentially reducing adverse health outcomes.

How similar studies have performed: While there have been studies on thyroid hormone action defects, this approach focusing on early diagnosis and monitoring tools is relatively novel.
