Investigating the role of pyrophosphate in arterial calcification for chronic kidney disease patients

Pyrophosphate: a New Biomarker to Predict Arterial Calcification in Chronic Kidney Disease

Not applicable Interventional Centre Hospitalier Universitaire de Nice · NCT04950439

This study is testing if low levels of a substance called pyrophosphate are linked to the buildup of calcium in the arteries of people with chronic kidney disease to help find better ways to manage heart risks.

What this trial studies

This study aims to explore the relationship between low levels of pyrophosphate (PPi) and the development of arterial calcifications in patients with chronic kidney disease (CKD) stages 3 and 4. A total of 252 participants with an estimated glomerular filtration rate (eGFR) between 20 and 59 ml/min/1.73 m² will be recruited and monitored over a three-year period. The study will involve collecting blood samples to assess PPi levels and their correlation with arterial calcification. The findings could provide insights into potential therapeutic strategies for managing cardiovascular risks in CKD patients.

Who should consider this trial

Good fit: Ideal candidates for this study are patients with chronic kidney disease stages 3 or 4 and an eGFR between 20 and 59 ml/min/1.73 m².

Not a fit: Patients who have undergone kidney transplantation or have acute inflammatory diseases or active cancer may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to new treatments that reduce arterial calcification and improve cardiovascular health in patients with chronic kidney disease.

How similar studies have performed: While the specific approach of using pyrophosphate in this context may be novel, previous studies have indicated a link between low PPi levels and arterial calcification in similar patient populations.
