Insights

This case report highlights a child who developed acute kidney injury (AKI) when treated with vancomycin and piperacillin/tazobactam. Renal function improved after discontinuing the antibiotics, suggesting a drug-related adverse event.

Area of Science:

  • Pediatric Nephrology
  • Clinical Pharmacology
  • Infectious Diseases

Background:

  • Concomitant use of vancomycin and piperacillin/tazobactam is increasingly reported to cause acute kidney injury (AKI) in adults.
  • Limited data exists regarding the risk of AKI associated with this antibiotic combination in pediatric populations.

Observation:

  • An 8-year-old girl in the pediatric intensive care unit developed AKI during treatment for pneumonia with vancomycin and piperacillin/tazobactam.
  • Discontinuation of both antibiotics led to the resolution of AKI, with serum creatinine returning to baseline.
  • The patient later tolerated piperacillin/tazobactam monotherapy without evidence of renal impairment.

Findings:

  • The Naranjo probability scale indicated a probable drug-related adverse event.
  • This case suggests a potential link between vancomycin and piperacillin/tazobactam combination therapy and AKI in children.

Implications:

  • Clinicians should maintain a high index of suspicion for AKI when prescribing this antibiotic combination to pediatric patients.
  • Vigilant monitoring of renal function and vancomycin drug levels is crucial.
  • Further prospective studies are warranted to determine the incidence and characteristics of AKI in children receiving vancomycin and piperacillin/tazobactam.

Acute Kidney Injury I: Introduction

Introduction:Acute Kidney Injury (AKI) describes a swift decrease in kidney function occurring over hours to days, characterized by the kidneys' failure to remove waste products from the bloodstream. This leads to dangerous complications like metabolic acidosis, fluid overload, and electrolyte imbalances, such as hyperkalemia, which can cause life-threatening arrhythmias. AKI is common in both hospital and outpatient settings, often triggered by dehydration, sepsis, or exposure to nephrotoxic...
