Study of Thyroid Hormone Treatment With Levothyroxine in Adults on Hemodialysis to Improve Quality of Life and Heart Health

What this Trial Is About

This research aims to evaluate the effects of thyroid hormone supplementation in patients undergoing hemodialysis who have elevated thyrotropin TSH levels, a common complication in chronic kidney disease. Previous studies have shown that higher TSH levels are linked to poorer quality of life and increased cardiovascular risks in these patients. The trial seeks to clarify whether levothyroxine treatment can improve patient-centered outcomes and cardiovascular health, as well as its metabolic effects in this population. Participants will be randomly assigned to receive either levothyroxine or a matching placebo for 24 weeks. Initial doses depend on their TSH levels, with adjustments after 8 and 16 weeks based on follow-up TSH measurements, aiming to maintain TSH within a target range. Both groups undergo similar pill titration schedules to maintain study balance. The trial is double-blind and placebo-controlled to ensure unbiased results. During the study, participants will have assessments of quality of life, coronary artery calcification, physical performance, endothelial function, vascular markers, body fat, muscle strength, heart function, and energy expenditure at baseline and after 24 weeks. These evaluations help researchers determine the impact of levothyroxine on health-related quality of life and cardiovascular parameters. The total study participation spans approximately six months with regular monitoring.
