High vs standard protein intake in critically ill adults with acute kidney injury on CRRT
Official title: Effect of High Versus Standard Protein Intake in Critically Ill Patients With Acute Kidney Injury Requiring Continuous Renal Replacement Therapy: A Randomized Controlled Trial (PROTEIN-CRRT)
Run by Chulalongkorn University · NCT07596043 · Data updated 2026-11-12
This study tests whether a higher protein diet helps adult ICU patients with acute kidney injury who are receiving continuous renal replacement therapy.

Is this trial a fit for you?
✓Likely a good fit
Adults (18+) with AKI requiring CRRT within 7 days of ICU admission who can tolerate at least 70% of target calories (20 kcal/kg/day) via enteral feeding.
✕Probably not a fit
Patients who cannot tolerate higher protein or have conditions that preclude higher protein intake may not benefit.

What this trial studies
In critically ill patients, severe illness drives muscle breakdown and weakness, especially when kidneys are injured and undergoing CRRT. The trial compares two protein feeding strategies to see if more dietary protein supports muscle preservation and recovery. Participants must be adults with AKI on CRRT and must receive enough calories enterally within the first week of ICU stay. The study is conducted at King Chulalongkorn Memorial Hospital in Bangkok and is sponsored by Chulalongkorn University. Outcomes focus on muscle-related recovery and safety of differing protein levels during critical illness.
Why it matters
Potential benefit: If successful, higher protein intake could improve muscle strength and shorten recovery times for ICU patients on CRRT.
How similar studies have gone: Prior research suggests protein supplementation may help in critical illness, but results vary by setting and renal replacement therapy; this trial addresses a specific, high-protein approach in CRRT patients.
