Fungal sinusitis

- In immunocompetent host, fungi in sinuses may be associated with nasal polyposis and do not routinely require antifungal therapy.

- In immunocompromised patients/diabetic ketoacidosis, a fungal infection can present as a cellulitis that may rapidly progress and be fatal. Surgical debridement is necessary.

Aspergillus spp
Rhizopus spp
Mucor spp

Immunocompetent

Empiric Therapy Dose Duration
Antifungal therapy not routinely recommended

Aspergillus

Empiric Therapy Dose Duration

Rhizopus/Mucor

Empiric Therapy Dose Duration
Amphotericin B 1-1.5mg/kg IV daily Until clinical and radiographic resolution and reversal of immunosuppression, if possible. Suppressive therapy then usually continued for at least 3-6 months, or life-long if continuing immunosuppression.
