Blood markers that may predict cardiorenal syndrome in people with chronic heart failure
Official title: Screening and Validation of Serum Biomarkers (SLPI, Serpin E1, CXCL10, CXCL13, Properdin) for Predicting Cardiorenal Syndrome in Patients With Chronic Heart Failure: A Prospective Cohort Study
Run by Affiliated Hospital of Nantong University · NCT07139626 · Data updated 2026-11-12
This project will test whether five blood proteins (SLPI, Serpin E1, CXCL10, CXCL13, and Properdin) can predict cardiorenal syndrome in adults with stable chronic heart failure.

Is this trial a fit for you?
✓Likely a good fit
Adults aged 18–75 with stable chronic heart failure (HFrEF, HFmrEF, or HFpEF) who can provide blood samples and complete 12 months of follow-up are eligible.
✕Probably not a fit
Patients with recent AKI, long-term dialysis or kidney surgery, active infections, autoimmune disease, recent cancer treatment, severe liver dysfunction, or recent use of nephrotoxic drugs are excluded and unlikely to benefit from the results.

What this trial studies
This prospective observational cohort will screen and validate five serum biomarkers (SLPI, Serpin E1, CXCL10, CXCL13, and Properdin) as predictors of cardiorenal syndrome (CRS) in adults with stable chronic heart failure (CHF). The screening phase compares biomarker levels between 30 CHF patients without kidney dysfunction and 30 CHF patients with established CRS using Luminex-based assays, and biomarkers with significant differences will be prioritized. In the validation phase, 90 CHF patients with normal kidney function will be followed for 12 months to determine which biomarkers predict subsequent development of CRS. The work builds on prior Luminex-based findings in post-cardiac surgery acute kidney injury that linked inflammatory, complement, and endothelial pathways to kidney injury and cardiorenal interactions.
Why it matters
Potential benefit: If successful, these biomarkers could enable earlier identification of CHF patients at high risk for CRS, allowing preventive measures and closer monitoring.
How similar studies have gone: Previous Luminex-based analyses found these biomarkers were altered in patients with post-cardiac surgery acute kidney injury, providing supportive preliminary evidence, though CRS-specific validation remains limited.
