Amphotericin B in neonates: deoxycholate or lipid formulation as first-line therapy – is there a ‘right’ choice?

Abstract

Purpose of review 

The aim is to compare the available evidence on the efficacy and safety of deoxycholate and lipid amphotericin B formulations (AMBF) in the treatment of invasive fungal disease (IFD) in neonates. The review also aims to summarize current practices and recommendations.

Recent findings 

To date most AMBF studies on neonates consist of retrospective reports and case series. The reviewed reports show that both amphotericin B deoxycholate (DAMB) and lipid formulations appear to have equal efficacy in treating IFD in neonates. The adverse effects of DAMB in neonates are considerably less than those in older children and adults. There is a trend of more nephrotoxicity reported with DAMB than with lipid formulations; however, the range reported is very wide (0–70%). Neonates with normal baseline renal function appeared to tolerate DAMB relatively well. A sodium intake of 4 mEq/kg/day may significantly reduce DAMB nephrotoxicity.

Summary 

Deoxycholate amphotericin B is inexpensive and effective in treating neonatal IFD. It appears to be safe for use as first-line therapy if the underlying risk for nephrotoxicity is low and renal function and potassium are monitored closely.
