Abstract

Sepsis-associated acute kidney injury (SA-AKI) is common among critically ill patients and represents a major contributor to both disease severity and mortality. The pathophysiology is multifactorial, involving systemic and microcirculatory hemodynamic disturbances, mitochondrial dysfunction, and cellular metabolic reprogramming. Recovery following AKI depends on the balance between adaptive repair mechanisms (endothelial repair, tubular epithelial regeneration) and maladaptive repair, which predisposes patients to chronic kidney disease progression.
Current therapeutic strategies focus on early recognition and timely management of sepsis, including appropriate antimicrobial therapy, fluid resuscitation, and vasopressor support when indicated. In addition, organ support plays a pivotal role, particularly renal replacement therapy (RRT) in severe AKI, although the optimal timing and dosing of RRT remain controversial.
