Insights

Concurrent use of amphotericin B and pentamidine isethionate may cause acute kidney injury in patients with acquired immune deficiency syndrome. However, amphotericin B with inhaled pentamidine or trimethoprim-sulfamethoxazole did not significantly impair renal function.

Area of Science:

  • Nephrology
  • Infectious Diseases
  • Pharmacology

Background:

  • Acquired immune deficiency syndrome (AIDS) patients often require treatment for opportunistic infections like systemic mycoses and Pneumocystis carinii pneumonia.
  • Amphotericin B is a critical antifungal agent, while pentamidine isethionate is used for Pneumocystis pneumonia.
  • Renal toxicity is a known concern with certain antimicrobial agents.

Observation:

  • Four cases of acute reversible renal failure were observed in patients with AIDS.
  • These patients were concurrently receiving amphotericin B and pentamidine isethionate.
  • No significant renal impairment was noted when amphotericin B was used with inhaled pentamidine or trimethoprim-sulfamethoxazole.

Findings:

  • The combination of intravenous amphotericin B and pentamidine isethionate was associated with acute reversible renal failure in AIDS patients.
  • This specific drug combination appears to pose a higher risk for nephrotoxicity compared to other regimens.
  • Renal function recovered after discontinuation of the offending agents.

Implications:

  • Clinicians should exercise caution when prescribing concurrent amphotericin B and pentamidine isethionate to AIDS patients.
  • Monitoring renal function is crucial in patients receiving this drug combination.
  • Alternative treatment strategies or careful monitoring may be necessary to mitigate nephrotoxicity risks.
