Comparison of Early Proton Pump Inhibitor Initiation Versus Usual Care on Acute Kidney Injury in Hemorrhagic Shock Patients

Официальное название

Comparison of Early Proton Pump Inhibitor Initiation Versus Usual Care on Acute Kidney Injury (CEPU-AKI) in Hemorrhagic Shock Patients: A Prospective Randomized Controlled Trial

Обзор

The investigators propose a single-center, randomized, controlled trial to determine whether early initiation of proton pump inhibitor (PPI), pantoprazole, will decrease acute kidney injury (AKI) for trauma patients presenting with hemorrhagic shock compared to routine timing of initiation of PPI. Kidney injury will be assessed by the urinary kidney injury biomarkers, and the incidence, severity and AKI-free days within first week and major adverse kidney events (MAKE) at day 30. The specific aims of the study will be achieved by a cohort of 100 patients to receive either early(study) or routine (control) administration of pantoprazole for 2 days after the initial injury insult.

Подробное описание

Traumatic injuries account for 10% of all deaths globally and are the leading cause of mortality for trauma patients under 46 in the United States. Hemorrhage is the primary cause of death in both civilian and military trauma scenarios worldwide. Following hemorrhage and traumatic brain injury, organ failure, including acute kidney injury (AKI), is the third leading cause of death in trauma patients. AKI occurs in up to 50% of patients with hemorrhagic shock and is linked to increased morbidity, extended hospital stays, progression to chronic kidney disease, and higher short- and long-term mortality rates. Even patients with mild AKI, as classified by the RIFLE criteria (Risk, Injury, Failure, Loss of kidney function, and End-stage kidney disease), face a 2.5 times higher risk of mortality. Battlefield conditions often delay access to definitive medical care for injured soldiers, highlighting the urgent need for effective shock treatments to minimize organ damage, such as AKI.

The investigators propose a single-center, randomized, controlled trial to determine whether early initiation of proton pump inhibitor (PPI), pantoprazole, will decrease acute kidney injury (AKI) for trauma patients presenting with hemorrhagic shock compared to routine timing of initiation of PPI.

Our study will include adults (over 18 years old) who meet the criteria for hemorrhagic shock, as these patients are more susceptible to hypoxic kidney damage due to bleeding and hypovolemia. This will allow us to assess whether early PPI initiation can better protect the kidneys during the early stages of hypoxic damage.

To evaluate this, the investigators will measure urinary kidney injury biomarkers in trauma patients to compare early pantoprazole initiation (study group) with the usual timing of PPI initiation (control group) (n=100, primary endpoint). Additionally, the investigators will assess whether early pantoprazole initiation decreases the incidence, severity, and number of AKI-free days within the first week post-hemorrhagic shock, as well as major adverse kidney events (MAKE: a composite of death, dialysis, renal hospitalization, or sustained kidney dysfunction) 30 days after the initial injury.

Вмешательства

• Препарат Protonix (Pantoprazole) 40 mg q 12 hrs for 2 days
  Within 2 hours of ED admission after inclusion criteria is met, administer 1st dose of Protonix (pantoprazole) 40mg, then followed by 40mg q12hrs for 2 additional days.
• Препарат Protonix (pantoprazole) 40 mg q 24 hrs for 2 days
  Administer 1st dose of 40mg Protonix (pantoprazole) at the usual timing (current practice: in the intensive care unit), then followed by 40mg daily for 2 additional days.
