  • Risk Factors
  • Nephrotoxicity
  1. See Nephrotoxicity Risk
  2. Concurrent medications that interfere with GFR autoregulation or renal blood supply

    3. Cycosporine
    4. Non-Steroidal Antiinflammatory drugs (NSAIDs)
    5. Tacrolimus
  • Evaluation
  • Criteria to consider stopping agent due to nephrotoxicity
  1. Relative Serum Creatinine increase 50% over baseline
  2. Absolute Serum Creatinine increase
    1. Serum Creatinine baseline <2 mg/dl: Creatinine increase 0.5 mg/dl over baseline
    2. Serum Creatinine baseline >2 mg/dl: Creatinine increase 1.0 mg/dl over baseline
  • Causes
  • Medication mediated injury by renal site

    1. See Acute Prerenal Failure
    2. Duretics (volume depletion)

    5. NSAIDs inhibit cyclooxygenase
      1. Depletes renal vasodilatory eicosanoids

        1. Volume depletion
        2. Elderly
        3. Edema
    6. ACE Inhibitors (and ARBs) lower renal perfusion
      1. Result in dilated efferent arterioles
      2. Decrease Glomerular Filtration Rate

    12. Interferon
    13. Proton Pump Inhibitors (e.g. Omeprazole)

    1. Occurs in 10-20% patients on 7 day course
    2. Results in non-oliguric increased Creatinine
    3. A single dose early in septic course is usually safe
