Background
- Candida is an important nosocomial infection that requires evaluation to identify a source: central line cathether, intravenous catheter, indwelling foley catheter, recent abdominal surgery with anastamotic leak
- Associated with candidemia with further hematogenous spread to visceral organs (heart, kidney, liver, spleen, eye, brain, skin, joints etc)
Clinical Features
- presence of biofilms on catheter
- fever and chills unresponsive to antibiotics
- chorioretinitis
- muscle abscesses
- skin lesions with satellite pustules
Differential Diagnosis
Evaluation
- positive blood culture
- positive culture of blood, tissue, urine from normally sterile sites
- biopsy of skin lesions for gram staining
- beta-D-glutan assay can be a diagnostic adjunct to blood cultures and identify systemic fungal infections weeks before positive blood cultures
Management[1]
- vascular catheter removal
- 1st line: IV Echinocandins (Caspofungin, Anidulafungin, Micafungin)
- Caspofungin 70mg IV day 1, 50mg IV Qdaily x 14 days following the last positive blood culture
- Anidulafungin 200mg IV day 1, 100mg IV Qdaily x 14 days following the last positive blood culture
- Micafungin 100mg IV Qdaily x 15 days
- Step down therapy: as early as 5 days, can step down to oral if blood stream is clear and patient can tolerate oral regime
- 2nd line: Fluconazole, Voriconazole
- Fluconazole 800mg IV loading dose, 400mg (6mg/kg) IV Qdaily for 14 days following first negative blood culture
- Voriconazole 400mg (6mg/kg) IV Q12 hours x 2 doses (loading dose), 200mg (3mg/kg) IV Q12 x 14 days following first negative blood culture (maintenance dose)
- Alternative: Amphotericin B is acceptable but carries a higher toxicity and side-effect profile
- 1mg/kg/day IV x 14 days following first negative blood culture
Disposition
- Admission
