Overview

Acute kidney injury (AKI) is an abrupt, potentially reversible decline in renal function occurring over hours to days, defined by a rise in serum creatinine, a fall in urine output, or both, with consequent retention of nitrogenous waste and disturbances of fluid, electrolyte, and acid-base balance. It is conventionally classified by mechanism into prerenal azotaemia (renal hypoperfusion from hypovolaemia, sepsis, or cardiac failure), intrinsic renal injury (most often acute tubular necrosis, but also interstitial nephritis and glomerular disease), and postrenal obstruction. Staging systems such as RIFLE, AKIN, and KDIGO grade severity by creatinine increment and oliguria. In the setting of severe viral respiratory illness, AKI may arise through haemodynamic instability, cytokine-mediated injury, direct tubular involvement, and microvascular thrombosis; nephrotoxic exposures including iodinated contrast media and certain drugs compound the risk. Cardiorenal interactions, delayed graft function after transplantation, and chronic kidney disease as a predisposing substrate are recurring clinical themes. The condition is associated with increased morbidity, prolonged hospitalisation, and progression to chronic kidney disease. Research published in this area examines pathophysiology, biomarkers, contrast nephropathy, transplant haemodynamics, and renal outcomes in critically ill and infected patients.
