Etiology

  • C. albicans (46%)
  • C. glabrata (26%)
  • C. parapsilosis (16%)
  • C. tropicalis (8%)
  • C. krusei (3%)
  • C. auris (rare): growing concern for multidrug resistance
  • Numbers based on https://doi.org/10.1086/599039

Risk Factors

  • Immune-compromised
  • Long-term and broad-spectrum antibiotic use, especially in ICU
  • Multiple or long-term IV lines, central lines, etc.
  • Total parenteral nutrition
  • Acute kidney injury, especially requiring dialysis
  • Abdominal surgery
  • Gastrointestinal perforations

Presentation

  • Positive blood culture for Candida spp.
  • Fever
  • Triad of bowel perforation, increase white cell count, and decreased platelets

Investigations

  • Blood culture
  • Blood count (increased WBCs, decreased platelets)
  • Echo to rule out endocarditis

Management

  • Never treat as a contaminant!
  • Requires ophthalmology consult to rule out endophthalmitis, ideally around 1 week after positive cultures
  • Antifungal therapy
    • First-line (stable patients): fluconazole if no risk factors for a resistant species
    • Alternative (resistance or septic): micafungin or another echinocandin
    • Alternative (last-line): amphotericin B
