Liposomal amphotericin B in critically ill paediatric patients.

WHAT IS KNOWN AND OBJECTIVE: Literature provides much evidence regarding liposomal amphotericin B treatment for fungal infections in neonates and infants. Relevant data regarding critically ill paediatric patients of older age are scarce. We aimed to present our experience regarding liposomal amphotericin B use in critically ill paediatric patients from a tertiary-care paediatric hospital in Athens, Greece.

METHODS: We prospectively identified all paediatric patients who received treatment with liposomal amphotericin B in the intensive care unit of a tertiary-care paediatric hospital during a 3-year period (2005-2008). Data were retrieved from the evaluation of the available medical records.

RESULTS AND DISCUSSION: Twenty-three (nine females, mean age: 26·4 months, range: 5-39 months) critically ill paediatric patients were included; 12 had malignancy. In 16 of the 23 included children, liposomal amphotericin B was administered for the treatment of confirmed fungal infections (all but one were invasive), whereas in seven patients, it was used as pre-emptive treatment. One patient received voriconazole concomitantly. Eleven of the 16 children with documented infections were cured; five improved. Six of the seven children who received pre-emptive treatment also showed clinical improvement. Nine deaths were noted, all attributed to underlying diseases. Two cases of hepatotoxicity and one case of nephrotoxicity (all leading to drug-discontinuation) occurred. Seven and five cases of mild reversible hypokalaemia and hyponatraemia, respectively, were also noted.

WHAT IS NEW AND CONCLUSION: According to the findings of our small case series, liposomal amphotericin B may provide a useful treatment option for fungal infections of vulnerable critically ill paediatric patients with considerable comorbidity.
