Long-Term Effects of Amphotericin B on Renal Function

Permanent Renal Damage

• The Centers for Disease Control and Prevention recommends that permanent nephrotoxicity is the primary long-term concern and is cumulative dose-dependent 1
• The nephrotoxicity manifests as both glomerular damage and tubular damage, causing azotemia and electrolyte wasting, respectively 1, 2

Chronic Electrolyte Abnormalities

• Renal tubular acidosis can persist long-term due to permanent distal tubular damage 1, 2
• Hypokalemia occurs in up to 80% of patients during treatment and may require ongoing supplementation even after drug discontinuation 2

Formulation-Specific Considerations

• The National Comprehensive Cancer Network recommends that lipid formulations have considerably less nephrotoxicity than conventional amphotericin B deoxycholate 3, 4

Monitoring Requirements

• Patients require long-term monitoring of renal function, electrolytes, and complete blood counts even after treatment completion 1, 5, 6

Prevention Strategies

• Hydration with 0.9% saline intravenously 30 minutes before each infusion significantly ameliorates nephrotoxicity 1, 2, 5
• The use of the lowest effective dose and shortest duration of therapy necessary is recommended to minimize long-term damage 4
