Summary

This study looks at whether giving more protein (over 1.2 grams per kilogram per day) to critically ill patients with acute kidney injury helps their kidneys recover faster or causes harm. Researchers will review medical records from 344 adults in five Argentine ICUs, comparing those who got standard versus higher protein. The goal is to find the safest and most effective protein dose to guide ICU nutrition.

Who is studied

The study population consists of critically ill adult patients (≥18 years) admitted to intensive care units at five tertiary hospitals in Argentina. Eligible patients are those receiving exclusive enteral or parenteral nutrition who present with acute kidney injury (AKI) or worsening chronic kidney disease according to KDIGO criteria. Patients with advanced chronic kidney disease (creatinine clearance \<30 ml/min/1.73 m²) or hemodialysis at admission, previous kidney transplant, severe liver disease, or body mass index (BMI) \>30 are excluded.

Inclusion Criteria: * Patients aged 18 years or older admitted to the ICU. * Patients receiving exclusive enteral or parenteral nutrition * Acute kidney injury or exacerbated chronic kidney disease according to KDIGO criteria (increase in creatinine greater than 0.3 mg/dL in less than 48 hours or a 1.5-fold increase in baseline creatinine in 7 days) Exclusion Criteria: * Patients diagnosed with chronic kidney disease with a creatinine clearance of less than 30 ml/min/m2 or on dialysis at admission. * Patients with a history of kidney transplantation * Patients with severe liver disease (Child-Pugh score \>7 points) * Patients with acute kidney injury undergoing renal replacement therapy at T0 * BMI\> 30
