Aspergillosis 169

■If present, have a low threshold for instituting high-dose ampho-
tericin, even in absence of conclusive data.
■Think of involving surgical services early if surgical excision for
biopsy or therapy (brain abscess, sinus disease) may be needed.

General Measures
■General supportive care, reverse neutropenia, dose reduction of cor-
ticosteroids and other immunosuppressives if possible; await bone
marrow recovery

specific therapy
Indications
■Everyone for whom invasive disease is suspected; this is a rapidly
progressive disease with a high mortality even if therapy is initiated
promptly.

Treatment Options
■Medical Therapy:
➣Voriconazole: Has replaced amphotericin as the initial agent of
choice. Start IV, can switch to PO after 7 days if improvement
seen.
➣Amphotericin:
Use at maximally tolerated doses.
Lipid-based formulations of amphotericin may be substituted
if the patient develops nephrotoxicity on therapy, or has base-
line impaired renal function.
➣Itraconazole:
Itraconazole oral therapy may be an option to initiate therapy
if the patient is not ill, for pulmonary disease, or as follow-
up therapy to amphotericin once the progression of disease is
halted.
Itraconazole cyclodextran solution may have increased
bioavailability.
➣Caspofungin:
In the echinocandin class, approved for invasive aspergillosis.
No PO form available. Commonly has been used in salvage
therapy.
➣Other agents:
New triazoles such as posaconazole and ravuconazole may be
effective alternatives for invasive disease.
