Acute kidney injury (AKI) involves inflammatory pathways. While biomarkers like neutrophil gelatinase-associated lipocalin and cystatin C show promise, maintaining fluid balance is key to preventing postoperative AKI.

Area of Science:

  • Nephrology
  • Biochemistry
  • Critical Care Medicine

Background:

  • Inflammatory mechanisms are increasingly recognized as key contributors to acute renal failure (ARF).
  • Understanding these pathways is crucial for identifying novel therapeutic targets.

Purpose of the Study:

  • To review inflammatory pathways implicated in acute renal failure.
  • To discuss potential new therapeutic targets for ARF.
  • To evaluate current biomarkers and preventative strategies for postoperative renal failure.

Main Methods:

  • Literature review of recent biochemical evidence on ARF.
  • Analysis of biomarker efficacy (neutrophil gelatinase-associated lipocalin, cystatin C vs. creatinine).
  • Evaluation of clinical trial data for fenoldopam and atrial natriuretic peptide.

  • Assessment of protective effects of volatile anesthetic agents.

    • Main Results:

    • Neutrophil gelatinase-associated lipocalin is a sensitive and specific biomarker of renal injury, potentially predicting perioperative renal outcomes.
    • Cystatin C is superior to creatinine for estimating glomerular filtration rate.
    • Current drugs show limited efficacy in preventing postoperative renal failure; fenoldopam and atrial natriuretic peptide trials are equivocal.
    • Volatile anesthetic agents may protect the kidney from ischemia, similar to cardiac preconditioning.

    Conclusions:

    • Maintaining adequate intravascular volume and perfusion pressure remains the most effective strategy for preventing postoperative acute renal failure.
    • Future strategies for renal regeneration involve bone marrow-derived stem cells and growth factors like insulin-like growth factor-1.
