Investigating lithium clearance in patients with acute kidney injury

Endogenous Lithium Clearance in Acute Kidney Injury

Observational University Hospital of North Norway · NCT05982340

This study is testing how well the kidneys clear lithium in critically ill patients with acute kidney injury to see if their ability to process the drug is affected.

What this trial studies

This observational study aims to evaluate the endogenous clearance of lithium in critically ill patients, particularly those diagnosed with acute kidney injury (AKI) due to sepsis. The study will involve collecting blood and urine samples from 30 participants, including 10 ICU patients with AKI, 10 patients without AKI, and 10 healthy controls. By measuring renal clearance of creatinine and lithium at multiple time points throughout the day, the researchers hope to determine if lithium reabsorption is impaired in the early stages of critical illness.

Who should consider this trial

Good fit: Ideal candidates include ICU patients diagnosed with acute kidney injury, patients without AKI, and healthy controls.

Not a fit: Patients with chronic kidney disease or those not critically ill may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance the understanding of kidney function in critically ill patients and improve management strategies for acute kidney injury.

How similar studies have performed: While the approach of using lithium clearance to assess kidney function is established, this specific application in critically ill patients with AKI is relatively novel.
