Preventing kidney injury after heart surgery with a proton pump inhibitor

Post-Cardiac Surgery Acute Kidney Injury Prevention by Administration of Proton Pump Inhibitor (P2 Trial): A Prospective Randomized Controlled Trial

Phase 2 Interventional The University of Texas Health Science Center, Houston · NCT06706258

This study is testing if giving the heart surgery patients a medication called pantoprazole can help prevent kidney injuries after their surgery.

What this trial studies

This clinical trial investigates whether administering the proton pump inhibitor pantoprazole perioperatively can reduce the incidence of acute kidney injury (AKI) in patients undergoing cardiac surgery. The study will randomly assign 400 adult patients to receive either pantoprazole or famotidine for three days following surgery. By examining molecular pathways involved in kidney protection, the trial aims to determine if pantoprazole can mitigate the risk of AKI and related adverse kidney events. The outcomes will be assessed at 30 days post-surgery, focusing on urine biomarkers and clinical events.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 to 90 scheduled for elective cardiac surgery with a moderate to high risk of developing AKI.

Not a fit: Patients with severe preoperative kidney impairment, those requiring dialysis, or those undergoing emergency surgery may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly reduce the occurrence of acute kidney injury in patients undergoing cardiac surgery, leading to better postoperative outcomes.

How similar studies have performed: While the use of proton pump inhibitors for kidney protection is being explored, this specific approach is novel and has not been extensively tested in the context of cardiac surgery.
