PREdiction of succeSSful weanING From Continuous Renal Replacement Theraphy: the Possible Role of Delta C-cistatin

IRCCS Azienda Ospedaliero-Universitaria di Bologna · NCT06714214

This study is testing if changes in a specific blood marker can help doctors know the best time to stop kidney support treatment in patients with acute kidney injury.

What this trial studies

This observational study aims to determine if changes in plasma concentration of c-cistatin can predict the optimal withdrawal time of continuous renal replacement therapy (CRRT) in patients with acute kidney injury. The study will involve patients who are naive to renal injury and are admitted to various intensive care units. By measuring c-cistatin levels from the initiation to the discontinuation of CRRT, researchers hope to identify a reliable biomarker for weaning off renal support.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 and older diagnosed with acute kidney injury who require CRRT.

Not a fit: Patients with chronic kidney disease, those requiring renal replacement therapy for reasons other than acute kidney injury, or those with certain exclusions like ongoing CRRT or neoplastic disease may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved timing for discontinuing renal support in acute kidney injury patients, potentially enhancing recovery outcomes.

How similar studies have performed: While this approach is observational and may have been explored in other contexts, the specific use of c-cistatin as a predictive marker for weaning from CRRT in acute kidney injury is relatively novel.
