How liver failure, fibrosis, and low inorganic pyrophosphate contribute to artery calcification in people awaiting liver transplant
Official title: Roles of Hepatic Insufficiency, Hepatic Fibrosis, and Inorganic Pyrophosphate in the Progression of Arterial Calcifications
Run by Centre Hospitalier Universitaire de Nice · NCT07201649 · Data updated 2026-11-12
This study tests whether liver transplantation in people with chronic liver disease restores blood inorganic pyrophosphate and slows or stops arterial calcification.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults listed for liver transplantation for chronic liver disease who do not have active viral replication and have MELD scores ≤25.
✕Probably not a fit
People with MELD scores above 25, ongoing viral replication, or who are not transplant candidates are not eligible and unlikely to benefit from the transplant-related PPi restoration tested here.

What this trial studies
This interventional study enrolls people who require liver transplantation for chronic liver disease and collects blood and urine samples around the time of transplant. Investigators will measure plasma inorganic pyrophosphate (PPi) levels and monitor markers of arterial calcification before and after transplantation to determine whether PPi is restored and calcification progression is altered. Patients with very high short-term mortality risk (MELD >25) or active viral replication are excluded. The design uses transplant as a physiologic intervention to link hepatic function, PPi metabolism, and vascular calcification.
Why it matters
Potential benefit: If successful, restoring liver function with transplant could normalize PPi levels and reduce future cardiovascular risk by preventing further arterial calcification.
How similar studies have gone: Previous observational work has found low PPi in cirrhosis and links between PPi deficiency and vascular calcification, but using liver transplantation to reverse PPi loss and halt arterial calcification is a novel and largely untested approach.
