Study of renal safety in amphotericin B lipid complex-treated patients.
To investigate the renal safety of amphotericin B lipid complex (ABLC), records from 3514 ABLC-treated patients with fungal infections were reviewed. The median change in predicted creatinine clearance (CCr) from baseline to the end of therapy was -3 mL/min (range, -119 to 118 mL/min); doubling of serum creatinine (S-Cr) level occurred in 13% of patients, and new dialysis was needed for 3% of patients. Patients with underlying renal disease who had received prior antifungal therapy demonstrated a median CCr of 0.5 mL/min (range, -107 to 52 mL/min). Despite increased risk for renal impairment in allogeneic hematopoietic stem-cell transplant recipients, only 17% of patients demonstrated end-of-therapy doubling of S-Cr levels, and the median change in CCr was -10 mL/min (range, -107 to 108 mL/min). In ABLC-treated patients, concomitant treatment with potentially nephrotoxic agents and a baseline S-Cr level of <2 mg/dL were factors predisposing for the development of nephrotoxicity. These data provide evidence that ABLC may be used safely to treat patients who are at increased risk for renal impairment.
