Salt sensitivity in kidney disease: a new clue from uromodulin?
NCT ID NCT06363097
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looked at how salt in the diet affects blood pressure in 130 adults with chronic kidney disease. Researchers measured a protein called uromodulin in urine to see if it predicts salt sensitivity. The goal was to understand why some patients' blood pressure rises more with salt, which could lead to better dietary advice.
