Fungi

OVERVIEW

  • Best empiric treatment for life-threatening fungal infection is amphotericin B (all fungi are susceptible)
  • fungal infection is termed mycosis

TYPES OF INFECTIONS

  • superficial, cutaneous and subcutaneous infections (e.g. oral thrush)
  • endemic mycosis (e.g. histoplasmosis, blastomycosis, coccidioidomycosis, sporotrichosis)
  • opportunistic infections (most important in ICU)

EXAMPLES OF PATHOGENIC FUNGI

Yeast

  • Candida spp
  • Cryptococcus spp
  • Pneumocystis spp (“a yeast-like fungus”)

Molds

  • Aspergillus
  • Zygomycetes (Mucor, Rhizopus)
  • Other (Scedosporium, Fusarium)

YEAST

Candida

  • C. albicans: fluconazole
  • voriconazole
  • flucytosine
  • echinocandins: caspofungin, micafungin, anidulafungin (first line for invasive candidemia)

Cryptococcus

  • triazoles: fluconazole, itraconazole
  • flucytosine

Pneumocystis

  • co-trimoxazole 10mg/kg of sulfamethoxazole
  • pentamidine isethionate
  • dapsone

MOLDS

Rhizopus (causes mucormycosis)

  • amphotericin B
  • (surgery!)

Aspergillus

  • itraconazole
  • voriconazole
  • echinocandins: caspofungin, micafungin, anidulafungin
