Vancomycin Use in Severe Sepsis with Acute Kidney Injury

Rationale for Use

The treatment of severe sepsis with an appropriate antibiotic is essential for survival and takes priority over concerns about potential nephrotoxicity, as stated by the ADQI consensus, which emphasizes that treatment of an infection with a necessary antibiotic should begin immediately to prevent or ameliorate AKI 1
The American Academy of Nephrology, as referenced in the ADQI consensus, recommends starting antibiotic treatment immediately in severe sepsis, as delaying therapy significantly increases mortality risk, which outweighs the risk of worsening kidney injury 1

The ADQI guidelines emphasize that each additional nephrotoxin increases AKI odds by 53%, and combining 3+ nephrotoxins doubles AKI risk, highlighting the importance of avoiding other nephrotoxins when using vancomycin 2, 1
The Surviving Sepsis Campaign recommends ensuring adequate resuscitation before attributing worsening renal function to vancomycin, with at least 30 mL/kg crystalloid resuscitation targeting MAP ≥65 mmHg, as volume depletion and hypoperfusion are major contributors to sepsis-associated AKI 3

The Surviving Sepsis Campaign recommends against initiating RRT for creatinine elevation alone without other definitive indications, such as severe acidosis, hyperkalemia, uremic complications, or refractory volume overload, and prefers continuous RRT over intermittent hemodialysis for fluid management in hemodynamically unstable patients 5, 6, 4
