Use of antifungal treatment and outcomes for Invasive Aspergillosis with a summary of notable factors in children.
(*This summary has been compiled from published data – it should not be substituted as a treatment protocol, original references should be consulted, ,not all antifungal drugs are licensed for paediatric use; no liability will be undertaken by the Aspergillus website or its staff)
|Drug||Target fungal infections||Dose per day||Pharmacokinetics||Important notes|
|Polyenes||Binds ergosterol in fungal cell membrane|
|0.7- 1.0 mg/kg daily over 2-4 h ||Similar to adult||High individual variation, renal toxicity.|
|Amph B lipid formulations:
|3-5mg/kg daily for lipid forms,
3-4 mg/kg for colloidal 
|Safety data same as adult||Less renal toxicity than Amphotericin B parent compd. Less fever, chills and rigors|
|Antimetabolites||Inhibitor of pyrimidine salvage pathway|
(in combination with Amphotericin B)
|100mg/kg (in four doses) day
Peak plasma levels for antifungal active 40-60 ug/ml 
|Insufficient data in children
|Variable drug clearance data|
|Triazoles||Inhibits lanosterol 14- a- demethylase|
|Fluconazole||Candida, Cryptococcus, Dermatophyte infection||12 mg/kg for neonates and 12 mg/kg in paediatric patients. ||See table 2 groll||Greater plasma clearance with shorter 1/2 life( not in premature) side effects include gastro intest disturbances and hepatic transaminase levels increased.|
|Oral soln >2yrs suggest starting dose 5mg/kg in 2 doses daily (to attain trough level of 0.5ug/ml 
IV data lacking
|In immunocompromised patients only here||Adverse effects vomiting, abnormal liver function, abdominal pain
*itra not approved for<18yrs so off label
|Voriconazole||Invasive Aspergillosis Fusarium
Scedosporium Candidiasis in non- neutropenics
|9 mg/kg/dose IV load day 1, then 8 mg/kg/dose or 9 mg/kg/dose PO maintainance. If >12 years, then load 6 mg/kg/dose and the 4 mg/kg/dose or give 200-300 mg PO per dose *1||Immunocompromised paediatricss with inv mycosis – has approval from FDA
Table 3 ??groll??
No data for <2 yrs so empirical .
|Ages 2-11 have higher elimination rates than adult which may result in lower non therapeutic doses.
No data <2 yrs on pharmacokinetics
|Posaconazole||Active against zygomycetes, broad spectrum.
Approved 2nd line treatment for:aspergollosis fusariosis, chrmoblastomycosis coccidioidomycosis >18yrs. Approved prophylaxis for AML , myelodysplasia, hematopoietic, GVHD and stem cell transplant
|No pharmacokinetcs <18yrs. In 12 patients less than 8yrs no basic differences in trough levels. Successful salvage reported in 5/11 and 6/10 with IF ie. similar to adult. Dosage safety and tolerance has been initiated by manufacturers for paediatrics. |
|Echinocandins||Inhibit 1,3 beta-D glucan synth in fungal cell wall|
|Anidulafungin||In adults licensed for candida||0.7-1.5mg/kg/day in children. Study of 19 granulocytopenic children w cancer similar to adults re plasma conc. ||No serious side effects in paediatric trial of cancer patients|
|50mg/m2 daily(70 mg day 1)for 3months –17yrs . In 0-3months, 25mg/m2 gave same exposure as for 3 month-17yrs. ||Very few serious side effects well tolerated, favourable safety profile. Success rates comparable to Amph B lipo.|
|Micafungin||100 mg/day <40 kg weight(2mg/kg) or 150 mg /day(4mg/kg), for oesophageal candidiasis and 50 mg/day for prevention. ||Licensed in EU for invasive candida and as prophylaxis for candida with allogeneic stem cell tr
Similar to adults
|In Neonates micafungin has a shorter half life – clearance is more rapid, so need a larger dose.
Recommend 4mg/kg in neonates with invasive candidiasis, higher dose 10 mg/kg with CNS involvement. Recommend liver monitoring (Alanine transaminase & Aspartate transaminase) during treatment
Data is mainly compiled from Groll & Tragiannidis 2010,
This website specialises in Aspergillus infections – but the lack of paediatric data has meant that we have included data for other types of fungal infections – where it may be useful.
